- A growing number of manufacturing industries are initiating efforts to address sustainability issues. A study by the National Association of Manufacturers indicated that the manufacturing sector currently accounts for over a third of all energy consumed in the United States. There are many areas and opportunities to reduce energy costs and pollution emissions within a manufacturing facility. One way to achieve an energy efficient manufacturing system is to measure and evaluate the combined impact of process energy from manufacturing operations, their resources (e.g., plant floor equipment), and facility energy from building services (e.g., ventilation, lighting). In this paper, issues associated with integrating production system, process energy, and facility energy to improve manufacturing sustainability are explored. A modeling and simulation case study of analyzing energy consumption in a precision casting operation is discussed.

A Case Study for Modeling Machine Tool Systems Using Standard Representations

Konferensbidrag (refereegranskat)abstract
- Machine models play an important role to support decision making for purchasing, scheduling, and routing in manufacturing. However, it is challenging to share a machine model that is developed using proprietary formats. A model of a fully assembled machining system in a neutral format can help overcome this challenge. Standard-based machine tool models will not only facilitate information reuse but also enable model exchange between systems. In this paper a case study is discussed to demonstrate the initial effort of a standard representation for a machining system including both component geometric and kinematics information. This standard-based machine model will be easily imported to another tool.

Digital Twin for Smart Manufacturing: the Practitioner's Perspective
- 2020

Konferensbidrag (refereegranskat)abstract
- The manufacturing sector is experiencing a technological paradigm shift, where new information technology (IT) concepts can help digitize product design, production systems, and manufacturing processes. One of such concepts is Digital Twin and researchers have made some advancement on both its conceptual development and technological implementations. However, in practice, there are many different definitions of the digital-twin concept. These different definitions have created a lot of confusion for practitioners, especially small- and medium-sized enterprises (SMEs). Therefore, the adoption and implementation of the digital-twin concept in manufacturing have been difficult and slow. In this paper, we report our findings from a survey of companies (both large and small) regarding their understanding and acceptance of the digital-twin concept. Five supply-chain companies from discrete manufacturing and one trade organization representing suppliers in the automotive business were interviewed. Their operations have been studied to understand their current digital maturity levels and articulate their needs for digital solutions to stay competitive. This paper presents the results of the research including the viewpoints of these companies in terms of opportunities and challenges for implementing digital twins.

A TEST IMPLEMENTATION OF THE CORE MANUFACTURING SIMULATION DATA SPECIFICATION

- This paper describes an effort of testing the Core Manufacturing Simulation Data (CMSD) information model as a neutral data interface for a discrete event simulation model developed using Enterprise Dynamics. The implementation is based upon a model of a paint shop at a Volvo Car Corporation plant in Sweden. The model is built for a Swedish research project (FACTS), which focuses on the work procedure of developing new and modified production systems. FACTS has found standardized simulation data structures to be of high interest to achieve efficient data collection in conceptual stages of production development programs. For the CMSD-development team, implementations serve as an approach to validate the structures in CMSD and to gather requirements for future enhancements. CMSD was originally developed to support job shops, but the results of this implementation indicate a good possibility to extend CMSD to also support flow shops.

Implementation of Core Manufacturing Simulation Data in Aerospace Industry
- 2008
-
Ingår i: Winter simulation conference.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This presentation will describe how Boeing implements the Core Manufacturing Simulation Data (CMSD) information model. The presentation will include visualization of manufacturing data for parts and tooling visibility in manufacturing industry. Simulation analyses are prepared by extracting and formatting data from real world production databases. This includes automatic data processing, automatic curve fitting for distribution functions, automatic CMSD file generation, and finally data is automatically fed to simulations.

Interoperability for Simulation of Sustainable Manufacturing
- 2010

Konferensbidrag (refereegranskat)abstract
- Sustainability has become a very significant research topic, it impacts many different manufacturing industries. To achieve sustainable manufacturing, designing manufacturing systems that have less negative impact on the environment is critical. Modeling and Simulation (M&S) is an essential ingredient for success of sustainable manufacturing through its ability to predict the effect of implementing certain facility, process, and product actions. M&S for sustainable manufacturing requires the exchange of information with a variety of manufacturing systems, applications, and databases. M&S also provides appropriate models and methods to tailor algorithms for performing accurate transformations of the data. This paper introduces a methodology to support interoperability among simulation tools and other manufacturing systems that support sustainability. The methodology describes how to collect and process the identified data in order to make it reusable for M&S stud-ies to achieve sustainable manufacturing. Three potential case studies are identified and discussed as a scope for future work.
