(författare) Learning factories for future oriented research and education in manufacturing 2017 Ingår i: CIRP annals. - : ELSEVIER SCIENCE BV. - 0007-8506 .- 1726-0604. ; 66:2, s. 803-826 Tidskriftsartikel (refereegranskat)abstract Learning factories present a promising environment for education, training and research, especially in manufacturing related areas which are a main driver for wealth creation in any nation. While numerous learning factories have been built in industry and academia in the last decades, a comprehensive scientific overview of the topic is still missing. This paper intends to close this gap by establishing the state of the art of learning factories. The motivations, historic background, and the didactic foundations of learning factories are outlined. Definitions of the term learning factory and the corresponding morphological model are provided. An overview of existing learning factory approaches in industry and academia is provided, showing the broad range of different applications and varying contents. The state of the art of learning factories curricula design and their use to enhance learning and research as well as potentials and limitations are presented. Conclusions and an outlook on further research priorities are offered. (C) 2017 Published by Elsevier Ltd on behalf of CIRP.

(författare) Cross-disciplinary Design Based on the Digital Factory as a Boundary Object 2016 Ingår i: Procedia CIRP. - : Elsevier. - 2212-8271. ; , s. 565-570 Konferensbidrag (refereegranskat)abstract In the domain of developing production systems, the design of a good factory is typically distributed over many disciplines and organizations to cover all involved technologies and levels of detail (process, logistics, machinery etc.). Modelling and simulation used to support the design process within each of the disciplines typically represent different contexts and perspectives. To cross the discipline borders and share experiences, to encourage innovation and make holistic decisions, one challenge is to interrelate various digital models and to reach a mutual system understanding between stakeholders. This paper presents a study based on principles from Social Science, Production Engineering, Computer Science and Information Design to address cross-disciplinary collaboration. Principles concerning visual communication and theories in regard to tangible boundary objects are used to clarify how to describe production system interdependencies in a digital factory context. Work in process of implementing a digital factory framework based on the principles is described, with a use case demonstrating the development of a digital factory for a new type of automotive vehicle.

(författare) The machine tool model-A core part of the digital factory 2009 Ingår i: CIRP annals. - : Elsevier BV. - 0007-8506 .- 1726-0604. ; 58:1, s. 425-428 Tidskriftsartikel (refereegranskat)abstract Machine tool models - the core parts of manufacturing systems - are important for many purposes during development of new or existing systems, from investment, through process planning, NC, layout design, usage, to end of life. Today a lot of important machine tool information is not managed and stored for easy reuse. A machine tool modelling approach is presented and structured in line with principles for generic standards utilizing a manufacturing system ontology for modelling machine tool concepts. It forms a contribution to management of information and knowledge in manufacturing.
6.	Li, Yujiang (författare) Architecting model driven system integration in production engineering 2017 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract System integration is a key enabler to maximize information value in an engineering context. The valuable information is normally represented by information models which play a decisive role in the implementation of system integration. The information models are designed to efficiently and effectively capture, process and communicate information among different functional and business units. However, use of the information models in implementing system integration is challenged by insufficient support from current settings of modeling architectures. This situation calls for new strategies to ease the use of information models.To address this challenge, this study presents a new twofold solution: Model driven system integration. It includes 1) a modeling architecture to guide the development of information models and 2) an integrated implementation process to guide the use of information models. Thus, this work improves practical applicability of an information model in its entire modeling lifecycle.The results contribute not only to the performance of modeling practices but also to improved understanding of information modeling in system integration. Implementation contexts and implementation models are introduced to develop an implementation-oriented modeling architecture. Further, the potential of information models as a knowledge base to sup-port implementation practices is identified.To concretely discuss behaviors and structures of information models, this study adopts ISO 10303 and the related standards as major references of existing information models.Case studies on model driven system integration validate this research in scenarios concerning kinematic modeling, kinematic error modeling, cutting tools classification and product catalogue modeling. Model driven system integration exhibits high efficiency in implementation, enhanced interoperability and increased value of information models.
7.	Li, Yujiang, 1985-, et al. (författare) Cutting Tool Data Representation and Implementation Based on STEP AP242 2013 Ingår i: Smart Product Engineering. - Berlin/Heidelberg : Springer Berlin/Heidelberg. - 9783642308161 - 9783642308178 ; , s. 483-492 Konferensbidrag (refereegranskat)abstract For cutting tool data exchange in manufacturing CAx (Computer-Aided technologies), standardized representation and classification of items and properties is important. ISO 13399 (Cutting tool data representation and exchange) provides a solution to represent cutting tool data classified with an ISO 13584 (Parts Library, PLib) based dictionary. However, ISO 13399 does not support classification of shape geometry directly, which limits its use. Another limitation is representing GD&T (Geometric Dimensioning and Tolerancing) as simplified general properties, which does not fulfill high semantic precision and validation rules. This research provides a unified solution to represent cutting tool parameters integrated with geometry and dedicated properties based on STEP AP242 (ISO 10303-242 Managed model-based 3D engineering). Standardized libraries such as the ISO 13399 dictionary can be reused with the modeling approach for AP242 cutting tool representation. Software is developed to validate and demonstrate how this solution facilitates the data integration process to support CAx applications.
8.	Li, Yujiang, 1985- (författare) Development architecture for industrial data management 2013 Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract Standardized information modeling is important for interoperability of CAx systems. Existing information standards such as ISO 10303 STEP have been proposed and developed for decades for this purpose. Comprehensive data structure and various implementation methodologies make such standards strong in support of different industry domains, information types, and technical requirements. However, this fact also leads to increased implementation complexity and workloads for CAx system developers.This licentiate proposes the development architecture, STEP Toolbox, to help users implement standards with a simplified development process and minimal knowledge requirements on standards. Implementation difficulties for individuals are identified with analysis on implementation of the information standards in three aspects: tasks, users, and technology. Then the toolbox is introduced with an illustration of design of behavior and structure. Case studies are performed to validate the toolbox with prototypes. Internal and external observation has shown the around two-month learning process skipped and a great amount of workload reduction in implementation with the utilization of this architecture.
9.	Li, Yujiang, 1985-, et al. (författare) Representation and exchange of digital catalogues of cutting tools 2014 Ingår i: ASME 2014 International Manufacturing Science and Engineering Conference, MSEC 2014 Collocated with the JSME 2014 International Conference on Materials and Processing and the 42nd North American Manufacturing Research Conference. - 9780791845806 ; , s. V001T04A027- Konferensbidrag (refereegranskat)abstract Information management for manufacturing resources such as cutting tools is an important research topic in the context of cloud manufacturing. Vendors and customers usually use catalogues to communicate information for such manufacturing resource. Incompatibilities of information in syntax, semantics, and structure among supply chains often result in inefficient manual sharing and management of the catalogue information. It is difficult for cloud based applications to pool information from various sources. This communication failure calls for a system neutral solution for data modeling and exchange to enhance interoperability of the cutting tool catalogue information. Previous studies has present solutions for representation of the cutting tool information with STEP AP242 (ISO/DIS 10303-242) with semantic classification referring to a PLib (ISO 13584, Part Library) based dictionary. This approach can be extended for the catalogue modeling, due to functionalities for specification and configuration control of general product variants in the same standard. With a modeling approach with standardized information schemas, system architecture to guide implementation is proposed to enhance the communication in practice. Relative elements to represent vendors' catalogues and customers' requirements are modeled. Associations to the PLib-based dictionary complete semantics and enable information mapping between vendors and customers. Principles of the mapping are identified to facilitate implementation of related software systems. Prototypes are developed to verify the proposed system architecture. The proposed solution is promising to migrate to other types of products than cutting tools, because the data models are based on the general product models defined in AP242.

(författare) System integration for kinematic data exchange 2014 Ingår i: International journal of computer integrated manufacturing (Print). - : Taylor & Francis. - 0951-192X .- 1362-3052. Tidskriftsartikel (refereegranskat)abstract Industry needs a system neutral solution for exchange of kinematic models. In this article, the first known valid implementation of kinematic mechanisms based on ISO 10303 Standard for the Exchange of Product (STEP) is presented. The result includes an implementation framework and two developed prototypes. Two major challenges of standard-based development are identified and generalised: data integration and system integration, which are solved by the framework. The two prototypes are implemented to establish kinematic data exchange between Siemens NX® and STEP-NC MachineTM via STEP AP214 files. Experiences of design and development of the applications are presented, and a validated case study of data exchange using the developed applications is shown. There are other attempts of using STEP as basis for modelling, but as the first valid STEP implementation on kinematics, this approach demonstrates the feasibility of pure STEP-based data exchange for kinematic mechanisms. The prototypes also show potential of utilising the framework for general standard implementations. The research is expected to motivate deeper understanding and extensive applications of the STEP standard in industry and academia.
11.	Li, Yujiang, 1985-, et al. (författare) User friendly development architecture for standardised modelling : STEP Toolbox 2014 Ingår i: International Journal of Manufacturing Research. - : Inderscience Enterprises Ltd.. - 1750-0591. ; 9:4, s. 429-447 Tidskriftsartikel (refereegranskat)abstract Standardised information modelling is currently an important solution of enhancing the interoperability of computer-aided technology (CAx) systems in the manufacturing industry. The success of this solution is critically dependent on the complexity of data structure and implementation methodology. This study presents development architecture, STEP toolbox, which enables users to implement information standards via a simplified process with minimised knowledge requirements. This study starts with an analysis of relevant user groups for different types of tasks and knowledge requirements. Then STEP toolbox is presented as the simplified development architecture that consists of conceptual modelling and an object-oriented application programming interface (API). It is more convenient for typical developers than the conventional implementation methodology. Based on results from test cases for implementing three prototypes, a two-month learning process required for average developers of the information standards is expected to be eliminated.

(författare) The K3P Knowledge Protection Model : To Separate Know-Why from Know-How in Engineering Contexts 2013 Ingår i: Section I - Privacy Modelling and System Engineering. - Barcelos, Portugal : Polytechnic Institute of Cávado and Ave. - 9789899824133 ; , s. 28-35 Konferensbidrag (refereegranskat)abstract Today, much emphasis is put on globalization, collaboration, integration, and standardization in the engineering world. While this generally is both necessary and desirable, it does raise one important question: How does a company protect its key competence against imitators, copycats, and plagiarisms? In a project we have studied this question from a product data perspective, i.e., we leave out legal-, commercial-, and IT-aspects. The traditional approach has been to rely on the physical protection of the drawing archive combined with simple security classification on the documents themselves. We found this to be too simplistic, and instead we have developed a more elaborate, but still tentative model to identify the data to be protected. This model starts with product characteristics, e.g., product type, product concept maturity, expected life, and degree of customization. Further, the business strategy, e.g., customer focus vs. technical leadership vs. operational excellence is described. These product and business properties are mapped to the relevant processes and methods within the company, e.g., product development or order handling, as well as to the supporting systems and information structures. Finally, mapping is made to the individual data elements which are to be protected. In this model we do not only identify the data elements themselves, but also the context within which they need protection. This context can thus be a customer order, a development project, or a certain time frame. We illustrate the use of our model with industrial test cases and conclude with a proposal for future work.

Konferensbidrag (refereegranskat)abstract Process planning is the activity of determining the manufacturing operations needed to produce a product. The knowledge work of process planning has been thoroughly investigated. Several ideas to automate process planning have been proposed but their success in practice has not yet been realized. Little attention has been given to design as an inevitable element in process planning and the role of human expertise in process design. From the premise that competent planners are a primary source of productivity this paper discusses process design, the role of human expertise and how CAPP systems could support human decision making.
14.	Shariat Zadeh, Navid, et al. (författare) An approach for manufacturing process representation in product lifecycle management 2013 Ingår i: Key Engineering Materials (Volume 572). Konferensbidrag (refereegranskat)abstract Current Product Lifecycle Management systems (PLM) have concentrated on product design, not on manufacturing engineering with its development of e.g. Material flows and layouts. This paper proposes an approach to describe how to represent the main required manufacturing process data using ontologies together with generic data standards. This approach makes it possible to develop translations between different software, and also providing users with the meaning of different concepts. It contributes to an efficient management of manufacturing information, with a focus on the material flow information as used in Discrete Event Simulation – DES.
15.	Shariat Zadeh, Navid, 1978-, et al. (författare) Integration of Digital Factory with Smart Factory Based on Internet of Things 2016 Ingår i: Procedia CIRP. - : Elsevier. ; , s. 512-517 Konferensbidrag (refereegranskat)abstract Internet of things (IoT) in manufacturing can be defined as a future where every day physical objects in the shop floor, people and systems (things) are connected by the Internet to build services critical to the manufacturing. Smart factory is a way towards a factory-of-things, which is very much aligned with IoT. IoT not only deals with smart connections between physical objects but also with the interaction with different IT tools used within the digital factory. Data and information come from heterogeneous IT systems and from different domains, viewpoints, levels of granularity and life cycle phases causing potential inconsistencies in the data sharing, preventing interoperability. Hence, our aim is to investigate approaches and principles when integrating the digital factory, IT tools and IoT in manufacturing in a heterogeneous IT environment to ensure data consistency. In particular this paper suggests an approach to identify what, when and how information should be integrated. Secondly it suggests integration between IoT and PLM platforms using semantic web technologies and Open Services for Lifecycle Collaboration (OSLC) standard on tool interoperability.

Further, the capability of integrating this data structure with other types of information such as geometry, e.g. for sizes of products or distances of transports, is of vital interest.
17.	Shariatzadeh, Navid, et al. (författare) Material flow data representation and integration based on STEP 2013 Ingår i: Internetworking Indonesia Journal. - 1942-9703. ; 5:1, s. 11-19 Tidskriftsartikel (refereegranskat)abstract A fundamental requirement for executing Discrete Event Simulation (DES) is incorporating a data structure that represents process, product and resource information, and their interrelations. Further, the capability of integrating this data structure with other types of information such as geometry (e.g. for sizes of products or distances of transports) is of vital interest. Manufacturing information is normally not integrated but is heterogeneous and stored in different Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) applications in the factory plant. Therefore this paper aims to describe how to represent the main required operational data of a manufacturing system for DES by using ISO 10303 Application Protocol 214 (STEP AP214) in order to fulfill the mentioned characteristics of data and information. Stochastic properties of manufacturing resources and corresponding processes such as measured cycle time and disturbances information are represented using application module 1274 (ISO 10303-1274) that defines a particular schema for probability distribution representation. A test implementation of the mentioned data including a graphical user interface has been carried out to show the feasibility of the research approach.
18.	Shariatzadeh, Navid, et al. (författare) Rapid Production Changes through the Coordination of Factory Layout Models and Activities 2013 Ingår i: Journal of Applied Mechanical Engineering. - : OMICS Publishing Group. - 2168-9873. Tidskriftsartikel (refereegranskat)abstract Changing the design of a factory in practice involves the change of a number of parallel and interdependent systems such as the machining resources and robot cells, the supply systems for electricity, water, air, heat and cooling, pneumatics and hydraulics, the systems for chip and waste handling, process fluid, communication networks, sprinkler systems, as well as the building construction. Thus the coordination of information and models, as well as of the design work activities, is of utmost importance to achieve a fast and flexible development process. This paper presents the results from a research project focusing on computer aided work processes and the communication of models between various stake holders in layout design. The primary objective was to provide methods for a coordinated factory development process with a facilitated information exchange and reuse of knowledge and models. Results concerning required layout and PLM (Product Lifecycle Management) functionalities, as well as modelling and communication principles, tested in an industrial case, are presented.

(författare) Software Evaluation Criteria for Rapid Factory Layout Planning, Design and Simulation 2012 Ingår i: 45th CIRP Conference on Manufacturing Systems 2012. - : Elsevier. ; , s. 299-304 Konferensbidrag (refereegranskat)abstract The objective of this paper is to specify functional requirements on software for rapid factory planning and design in a digital factory context. In comparison with other studies that focus on particular aspects of layout development, this work deploys a comprehensive approach, based on industrial needs, to determine main functionalities for factory layout software. The research considers integration of different layouts where original equipment manufacturer and other stakeholders involved in factory layout design collaborate with each other to develop, or extend a factory. Therefore; engineering change management and data exchange in a system neutral format are taken into account as main pillars.
20.	Shariatzadeh, Navid, et al. (författare) Using Linked Data with Information Standards for Interoperability in Production Engineering 2015 Ingår i: RESEARCH AND INNOVATION IN MANUFACTURING: KEY ENABLING TECHNOLOGIES FOR THE FACTORIES OF THE FUTURE. - : Elsevier BV. ; , s. 502-507 Konferensbidrag (refereegranskat)abstract Design and verification of factory layout and material flow is a multidisciplinary, knowledge-intensive task which requires a collaborative framework where all specialists involved can communicate, interact, manage and visualize different models. However, the communication of digital models comes with challenges. First of all the information resides in various systems and applications, in different formats and with various levels of detail and viewpoints. Moreover, models share common properties and it is common that these properties influence each other. Hence modification of one model should be propagated to other models, which need to be coordinated.To deal with the data exchange and integration problem, information standards such as ISO 10303 have been developed. ISO 10303 (STEP) has shown a strong capability to represent rich information models in a wide variety of industrial domains for the purpose of exchanging data. However, STEP is intrinsically complex and sometimes adds unnecessary level of detail to information to be shared. On the other hand, the Open Services for Lifecycle Collaboration (OSLC) initiative provides a minimalistic set of standardized information models, focusing on the most common concepts within a particular domain. Assuming a loosely-coupled distributed architecture of tools and services, OSLC adopts the Linked Data approach to ensure data consistency across the data resources.How can we combine STEP’s rich information model for data exchange, with OSLC’s minimalistic approach for data integration?The aim of this work is to show the applicability of using these two complementary paradigms – and their corresponding standards - to support interoperability and data integration in a heterogeneous IT environment for material flow analysis and layout design. To this end, an industrial case study was implemented through the information standard STEP and the OSLC specifications to verify the suggested approach.
21.	Sivard, Gunilla (författare) A generic information platform for product families 2001 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract The research work detailed in this dissertation relates to the computer representation of information which concerns product families and product platforms. Common to competitive companies today, is the quest of designing products and processes to meet a large variety of customer needs, in short time, and based on few resources. One way to succeed with this endeavor is to plan for the variety and design a modular, or adaptive, product family based on a common platform of resources. To further increase the efficiency in delivering customized products in time, a computer processible model of the family is created, which is used to realize a customer specific product variant during the order phase. The objective of this research is to define a generally applicable model of product family information for the purpose of supporting various applications, and for achieving an efficient utilization of information. The approach is to define a model of the product family according to the theory of Axiomatic Design, which reflects the trace from various requirements to functions and different properties and components of the product. By representing information from design in a generally applicable format, this information can be reused when building the configuration models of the order phase. By adapting the model to an existing standard, information exchange between systems is supported, and access is provided to information concerning detailed physical parts as well as constructs addressing various use and version management. Contributions include a description of a model architecture with reusable functional solutions, interfaces, structures and interrelations between platform solutions and product family. Further, it is described how to extend and model the domains and interrelations of axiomatic design in an information model, which is adapted to the product modeling standard of ISO10303-214.

In this article, some basic concepts concerning model driven development are put forward, and a generic model driven work process is described, which covers the manufacturing development activities on a comprehensive level. Further, a case study of the development of a new motor line at the truck company Scania is presented to exemplify the concepts. The model driven approach is described on a more detailed level in the context of process planning.
23.	Sivard, Gunilla (författare) AN INTEGRATED ARCHITECTURE FOR FUNCTIONAL PRODUCTS 2003 Ingår i: INTERNATIONAL CONFERENCE ON ENGINEERING DESIGNICED 03 STOCKHOLM, AUGUST 19-21, 2003. - 1904670008 Konferensbidrag (refereegranskat)abstract There is an increasing trend in industry of selling services in addition to physical products. Infunctional sales, companies sell the service of delivering the function of the product asopposed to selling the product itself. While there is a long tradition of structured developmentand management of purely physical goods, there is a lack of such methods for services, andfor the mixture of service and goods - so called functional products.This paper describes an effort of defining a formal model of services, contributing to theefforts of structuring, visualizing and managing functional products in analogue with purelyphysical products.A modular architecture for services is presented, based on the paradigm of defining servicesas discrete, decomposable activities. Sub activities, so called service modules, are described interms of the activity’s properties and interfaces to other service modules. Since the method isbased on principles for uncoupled design, it provides support for creating transparent andflexible architectures with a minimum of built in dependencies between functions and theirphysical implementation.The service module aggregation and representation principles are described in relation to anindustrial distribution case.

In this type of design. technical prerequisites and the range of customer requirements are typically the same over time. From time to time there are larger changes in manufacturing methods and customer needs though. Thus the degree of aiutomation in a design support system can be fairly large, but it still needs to be interactive and flexible for changes. The testcase presented is based on an industrial application, implemented using a commercial CAD system and a CLP (Constraint Logic Programming) system. Special emphasis is put on interactivity - the collaboration between a designer and automated design system.

This has led to an increased demand on innovations concerning new materials and product- and process technologies, as well as on new business models for a better utilization of products and materials.Most innovations occur through a learning process where various actors, individuals as well as organizations, take part. Breakthroughs do not necessarily occur within the research or development departments, they are equally likely to occur during production or utilization. The challenge thus lies in providing platforms and tools for cross-divisional, collaborative innovation and for sharing Best Practices.This paper describes an initiative at KTH Royal Institute of Technology for supporting the integration of various company disciplines and external expertise through a collaborative framework where industry and academy can collaborate, supported by modeling, simulation and visualization during the innovation process. The approach combines theories and methods concerning innovation and digital factories and emphasizes aspects concerning learning, communication and collaboration.
26.	Sivard, Gunilla, et al. (författare) Modules Information Modelling in Evolvable Production Systems 2012 Konferensbidrag (refereegranskat)abstract The objective of this paper is to study the modeling of information concerning modules of highly adaptable reconfigurable production systems used by various stakeholders in a supply chain. Evolvable Production Systems (EPS) are taken as underlying paradigm for this study. EPS targets highly adaptable mechanical and control solutions that can enhance reusability and interoperability of modules, enabling lifetime extension of the modules and short deployment times at the shop floor level. Implementation of such a system requires suitable methods to capture structure and to represent information for easy access and sharing of information. Therefore this paper aims to analyze and discuss the possibility to represent the required information in module modeling based on generic information standards together with the ontology of the modules.

In this paper we propose a new approach BIC, Business Information Context, to define contexts for accessing, viewing, and managing this complex information. BIC structures information based on key domains: business drivers, business processes, information entities, product characteristics, and information systems. We compare BIC with other and simpler approaches, like views and contexts used in the ISO 10303 (STEP) standards, design methodologies, and PLM systems. We illustrate the definition and use of BIC with an implementation of an application forprotecting a company’s intellectual property.

Konferensbidrag (refereegranskat)abstract This paper presents a model for describing machine tools based on the STEP standard AP239 as a neutral format for communicating information throughout production development and operation. The machine model is further defined at a reference data level, where concepts regarding machine tools are defined from four main viewpoints: process planning, investment process, factory planning and operation/improvement. The concept models extend the standard and define the specific machine tool information. The utilization of the machine model is exemplified in a use case.

(författare) Service Oriented Integration of Distributed Heterogeneous IT Systems in Production Engineering Using Information Standards and Linked Data 2017 Ingår i: Modelling and Simulation in Engineering. - : Hindawi Publishing Corporation. - 1687-5591 .- 1687-5605. Tidskriftsartikel (refereegranskat)abstract While design of production systems based on digital models brings benefits, the communication of models comes with challenges since models typically reside in a heterogeneous IT environment using different syntax and semantics. Coping with heterogeneity requires a smart integration strategy. One main paradigm to integrate data and IT systems is to deploy information standards. In particular, ISO 10303 STEP has been endorsed as a suitable standard to exchange a wide variety of product manufacturing data. One the other hand, service-oriented tool integration solutions are progressively adopted for the integration of data and IT-tools, especially with the emergence of Open Services for Lifecycle Collaboration whose focus is on the linking of data from heterogeneous software tools. In practice, there should be a combination of these approaches to facilitate the integration process. Hence, the aim of this paper is to investigate the applications of the approaches and the principles behind them and try to find criteria for where to use which approach. In addition, we explore the synergy between them and consequently suggest an approach based on combination of them. In addition, a systematic approach is suggested to identify required level of integrations and their corresponding approaches exemplified in a typical IT system architecture in Production Engineering.
