- Operation sequences are central in the interaction between product and manufacturing development. This is because the sequences create an understanding of how a product is manufactured. The high degree of complexity in managing and planning manufacturing operations during the development of a configurable product and manufacturing platform requires a new and more flexible sequence planning approach. By integrating configurable product and manufacturing system platform descriptions, product variance, manufacturing system flexibility, and product and manufacturing system complexity can all be efficiently adapted to each other by considering interrelated constraints. Such an integrated platform system also provides the information required to describe the operations needed to manufacture an instantiated product variant. This paper proposes an approach in which sequences are viewed based on the relations among self-contained operations, thus saving engineers from manually constructing sequences for each product variant. The sequences of operations related to, for example, the part flow for a specific platform configuration, robot operations or operator tasks can be automatically visualized through the use of different perspectives.

Conference paper (peer-reviewed)abstract
- Not all investments in PLM (Product Lifecycle Management) are successful. Measuring the business effects of a PLM solution is essential, but can only be applied subsequent to solution deployment. It could be more powerful to make an early evaluation of the PLM solution, resulting in the business benefits, making corrections possible prior to deployment.In this paper, a method to identify risks associated with a PLM solution is proposed based on an architecture model of a PLM solution and available PLM solution guidelines. Its use is demonstrated in an industry case and evaluated as compared to its intended use. The intention is that identified risks can help identify change proposals to the PLM solution or to obtain a better understanding of the consequences for solution deployment.The findings indicate that the method is a useful support for identifying risks associated with a PLM solution. However, additional testing of the method in real settings is necessary to strengthen that indication.

On the Interplay between Platform Concept Development and Production Maintenance
- 2017
-
In: Proceedings of the International Conference on Engineering Design, ICED. - 2220-4334 .- 2220-4342. ; Vol. 3: Product, Services and Systems Design

Conference paper (peer-reviewed)abstract
- To meet a broad customer-base, platforms can be used to achieve commonality and distinctiveness among a family of products. However, producibility of product variants are typically not ensured until late in the platform development phases. This may lead to increased production disturbances. To understand challenges in ensuring producibility of a product family in the early phases of platform development, this paper adopts the concept of lifecycle meetings to describe the interplay between platform concept development and production maintenance. Based on this description, we reason that to make early and credible cross product-production decisions, production system capabilities ought to be regarded as dynamic rather than static. While static implies as designed, dynamic implies change over time. In this paper, maintenance is regarded as one dynamic aspect of production. This reasoning is supported by a theoretical perspective and an illustrating case from the aerospace industry. The contribution of this paper may form the basis for future research on platform development and the effect of product variety on production systems.

Evaluating software security maturity using OWASP SAMM : Different approaches and stakeholders perceptions
- 2024
-
In: Journal of Systems and Software. - : Elsevier. - 0164-1212 .- 1873-1228. ; 214
-
Journal article (peer-reviewed)abstract
- Background: Recent years have seen a surge in cyber-attacks, which can be prevented or mitigated using software security activities. OWASP SAMM is a maturity model providing a versatile way for companies to assess their security posture and plan for improvements. Objective: We perform an initial SAMM assessment in collaboration with a company in the financial domain. Our objective is to assess a holistic inventory of the company security-related activities, focusing on how different roles perform the assessment and how they perceive the instrument used in the process. Methodology: We perform a case study to collect data using SAMM in a lightweight and novel manner through assessment using an online survey with 17 participants and a focus group with seven participants. Results: We show that different roles perceive maturity differently and that the two assessments deviate only for specific practices making the lightweight approach a viable and efficient solution in industrial practice. Our results indicate that the questions included in the SAMM assessment tool are answered easily and confidently across most roles. Discussion: Our results suggest that companies can productively use a lightweight SAMM assessment. We provide nine lessons learned for guiding industrial practitioners in the evaluation of their current security posture as well as for academics wanting to utilize SAMM as a research tool in industrial settings. Editor's note: Open Science material was validated by the Journal of Systems and Software Open Science Board. © 2024 The Author(s)

Development of product platforms: Theory and methodology
- 2017

In: Concurrent Engineering Research and Applications. - : Sage Publications. - 1063-293X .- 1531-2003. ; 25:3, s. 195-211

Journal article (peer-reviewed)abstract
- There is a trend toward increased customization of goods to satisfy a wide range of customers using product platforms. However, there is an erroneous notion that product platforms can only be used to provide economic viability in production thanks to the reuse of physical components among a family of products. Yet, this is a limited perception of the potential of a product platform. In this article, an object-oriented approach to support the development of product platforms is proposed to increase efficiency through reuse and flexibility of designs among a family of products. Two modes of the platform development process are addressed: platform preparation and platform execution. Platform preparation prescribes the methods needed to model platform objects, using enhanced function-means models and set-based concurrent engineering processes. During the platform execution process, sets of design alternatives can be configured concurrently throughout the conceptual, system, and detailed phases of the platform development. Three cases illustrate how the same approach may be used in different design scenarios: design space exploration and extension, supply-chain collaboration, and configure-to-order. The approach supports system architects and design engineers in making design decisions that propel the platform development work by enabling analysis in stages where designs are immature and evaluating the goodness of the alternatives early. Ultimately, product platforms can be efficiently developed for modularity and scalability to find feasible product variants and meet the needs of a multitude of customers.

Assessing Producibility of Product Platforms Using Set-Based Concurrent Engineering
- 2016
-
In: Advances in Transdisciplinary Engineering. - 2352-751X .- 2352-7528. - 9781614997030 ; 4, s. 35-44

Conference paper (peer-reviewed)abstract
- This paper presents a method to facilitate model-based producibility assessments of product variants in the early phases of platform development. The approach uses set-based concurrent engineering principles to explore and narrow down a design space towards feasible alternatives. A case including tool accessibility and assembly robustness of an aerospace sub-system platform is used to demonstrate the approach. The assessment activities can be prepared in parallel, and support the concurrency needed, across design and manufacturing, to serve improved process efficiency. Ultimately, the approach may reduce late design modifications thanks to increased reuse of manufacturing knowledge, as well as reduce cost thanks to less physical prototyping and testing.

Mediating constraints across design and manufacturing using platform-based manufacturing operations
- 2017
-
In: Proceedings of the International Conference on Engineering Design, ICED. - 2220-4334 .- 2220-4342. ; 6:DS87-6, s. 179-188
-
Conference paper (peer-reviewed)abstract
- To meet the needs of an array of customers, platforms can provide means to achieve commonality and distinctiveness among a family of products. However, typically the producibility of product variants are not ensured until the late platform development phases. This may lead to increased development lead-time, due to lack of integration across design and manufacturing. To be better suited in making early producibility assessments, a model to improve the integration across product platforms and manufacturing platforms is presented. The model is embodying manufacturing operations and marries platform models of two technical systems – products and manufacturing equipment. To serve the concurrency needed to explore cross product-manufacturing alternatives during the early phases of platform development, manufacturing operations can be modeled to serve improved integration of product platforms and manufacturing platforms. By modeling functions, control parameters, and key characteristics, the constraints across design and manufacturing can be mediated.

Using product and manufacturing system platforms to generate producible product variants
- 2016
-
In: Procedia CIRP. - : Elsevier BV. - 2212-8271. ; 44, s. 61-66
-
Conference paper (peer-reviewed)abstract
- Product platforms have proven efficient as a means to reduce lead-time and increase product quality simultaneously. When using platforms to generate a family of products, the number of variants that need to be managed in manufacturing increases. To succeed with this, the manufacturing system needs to be maintained in a similar level of flexibility as the product platform. However, there is seldom a joint decision behind each and every conceptual product variant during development, regarding capability in manufacturing. For example, when considering producibility, some product variants require better tolerances than what the manufacturing processes can deliver. This uncertainty can be reduced, by making producibility analyses of a set of conceptual product variants. By performing several different analyses, knowledge can be gained, and joint decisions can be made about cross product-manufacturing aspects. The activities can be systematically arranged to gradually eliminate unfeasible conceptual product variants. In this paper we show how an integrated PLM architecture can be used to create sufficient knowledge as a basis for joint product and manufacturing decisions. The utmost company benefit of this is to reduce lead-time by taking manufacturing capability into account when developing product families.

A Two-Stage Model of Adaptable Product Platform for Engineering-to-Order Configuration Design
- 2015
-
In: Journal of Engineering Design. - : Informa UK Limited. - 1466-1837 .- 0954-4828. ; 26:7-9, s. 220-235

Journal article (peer-reviewed)abstract
- Product platforms are used to enable mass-customization to serve a large number of different market segments. The products are configured-to-order, meaning they are compiled using a variety of pre-developed building blocks. However, the building blocks that make up a traditional platform can only serve customer requirements that are known. Engineering-to-order development serves companies where customer requirements vary frequently. Here, designs are tailored to fit specific customer requirements upon request, an approach which is time consuming if serving a large number of different customers. This paper presents an approach for engineering-to-order configuration design. It comprises a two-stage model that enables design reuse while simultaneously keeping flexibility to manage changes in customer requirements. The proposed artifact model is configured modularly to progress the design work and to create an architecture to work with, and scalable flexibility is maintained until the customer requirements are considered stable enough to optimize the final design. An illustrative case shows the approach’s feasibility to two-stage configuration of a rear frame of a jet engine. While using over-all design considerations to select modules, trade-off curves are used for final scalable configuration. A change in customer requirements is accommodated by scalable flexibility, thereby creating an adaptable product platform.
