Abstract [en]

Design automation systems are implemented by many manufacturing companies to automate the repetitive and time-consuming design tasks. By automating such tasks, the designers have more time to focus on creativity and offer more customized solutions to the customers.

To automate a design task, first, the design knowledge should be captured from designers. This type of knowledge which is usually understandable by humans should be structured and formalized. Next, computer codes and scripts (that are mostly understandable by computers/expert persons) are created to execute the knowledge and provide the desired output.

To support maintenance of computer codes and scripts in a design automation system, it is necessary to know what, how and why about that piece of code/script. In order to support maintenance of the systems, we represent the system’s knowledge in form of knowledge objects. Knowledge objects are executed in run time and consist of two parts: computer readable and human readable. The focus in this paper is on the human readable which we call it “design description”. A MOKA-based framework is provided to create design descriptions for the computer readable parts. The design descriptions help engineers to understand and if needed update the computer readable parts, which in a wider aspect support maintenance of the whole system. E-books were used as a way to represent the design descriptions and a case study is provided to explore the results of the research.

Abstract [en]

Knowledge objects are used to automate engineering processes in a flexible and scalable way. The focus of knowledge objects has been the automation of engineering design. However, in this paper we present a way to integrate knowledge objects into e-books so that formalized engineering knowledge can be read by any stakeholder and still be automatically applied by the system from the same file. The paper shows how different stakeholders throughout the life-cycle of a design automation system benefit from the knowledge object and e-book integration, how the integration is done and an example where the integration was applied. The example is a real example from industry.

Abstract [en]

As the markets’ needs change rapidly, developing a variety of products that meet customers’ diverse needs is a competitive factor for many manufacturing companies. Development of highly customized products requires following an engineer-to-order business process to allow the products to be modified or adapted to new customers’ specifications, which brings more value to the customer and profit to the company.

The design of a new product variant involves a large amount of repetitive and time-consuming tasks but also information handling activities that are sometimes beyond human capabilities. Such work that does not rely so much on creativity can be carried out more efficiently by applying design automation systems. Design automation stands out as an effective means of cutting costs and lead time for a range of well-defined design activities and is mainly considered as a computer-based tool that processes and manipulates the design information.

Variant design usually concern generating a new variant of a basic design, that has been developed and proved previously, according to new customer’s demands. To efficiently generate a new variant, a deep understanding of the intention and fundamentals of the design is essential and can be achieved through access to design rationale—the explanation of the reasons and justifications behind the design.

The maintenance of product families and their corresponding design automation systems is essential to retaining their usefulness over time and adapting them to new circumstances. Examples of new circumstances can include the introduction of new variants of existing products, changes in design rules to meet new standards or legislations, or changes in technology. To maintain a design automation system, updating the design knowledge (e.g. design rules) is required. The use of design rationale will normally become a necessity for allowing a better understanding of the knowledge. Consequently, there is a need for principles and methods that enable the capture and structure of the design rationale and sharing them with the users.

This study presents methods and tools for modeling design knowledge and managing design rationale in order to support the utilization and maintenance of design automation systems. Managing design rationale concerns enabling the capturing, structuring, and sharing of design rationale. The results have been evaluated through design automation systems in two case companies.

Abstract [sv]

Att kunna erbjuda kundanpassade produkter har blivit allt viktigare för många tillverkande företag. Utformningen av en ny produktvariant involverar en stor mängd repetitiva och tidskrävande uppgifter men även informationshanteringsaktiviteter som ibland är bortom mänskliga möjligheter. Sådant arbete som inte förlitar sig så mycket på kreativitet kan genomföras mer effektivt genom att använda designautomatiseringssystem. Designautomatisering framstår som ett effektivt sätt att minska kostnader och ledtid för en rad väldefinierade designaktiviteter och betraktas huvudsakligen som ett datorbaserat verktyg som analyserar och syntetiserar designinformationen.

Variantdesign handlar vanligtvis om att skapa en ny variant av en grundläggande design, som har utvecklats och bevisats tidigare enligt nya kunders krav. För att effektivt skapa en ny variant är en djup förståelse för designens avsikt och grundläggande uppbyggnad avgörande och kan uppnås genom tillgång till ”design rationale”- förklaringen av skälen och motiveringarna bakom designen.

Underhållet av produktfamiljer och deras motsvarande designautomatiseringssystem är viktigt för att behålla användbarheten över tid och anpassa dem till nya omständigheter. Exempel på nya omständigheter kan innefatta införande av nya varianter av befintliga produkter, ändringar av designregler för att uppfylla nya standarder, lagstiftningar eller tekniska ändringar. För att upprätthålla ett designautomatiseringssystem krävs uppdatering av designkunskapen (t ex designregler). Användningen av design rationale kommer normalt att bli en nödvändighet för att ge en bättre förståelse av kunskapen. Följaktligen finns det ett behov av principer och metoder som möjliggör fångande och strukturering av design rationale och dela dem med användarna.

Denna studie presenterar metoder och verktyg för modellering av designkunskap och hantering av design rationale för att stödja utnyttjande och underhåll av designautomatiseringssystem. Vid hantering av design rationale gäller det att göra det möjligt att fånga, strukturera och dela med sig av design rationale. Resultaten har utvärderats genom att undersöka effekterna av dem i designautomationssystem i två företag.

Implementing design automation systems to automate repetitive and time consuming design tasks enables engineer-to-order manufacturers to perform custom engineering in minimum time. To maintain a design automation system, regular updating of design information and knowledge is necessary. Consequently, there is a need of principles and methods to support capturing and structuring associated knowledge, specially, design rationale. In this paper a method for capturing, structuring, and accessing to design rationale in order to support maintenance of design automation systems is presented. The method is tested through a design automation system that develops FEA (finite element analysis) models automatically. The results are evaluated in a case company which is a supplier to the automotive industry serving many brands and car models which each more or less requires a unique solution.

Abstract [en]

Developing customized products is the business case for many manufacturing companies striving to fulfill the customers’ specific needs. When manufacturing customized products it is often necessary to also develop corresponding customized manufacturing tooling. There is a need to support concurrent development of new product variants along with their manufacturing toolsets. The communication between design engineers and manufacturing engineers is hence a key issue that if solved would enable design engineers to foresee how changes in product design affect tooling design and vice versa. To understand the correlation between the design of a product and its corresponding manufacturing tools, access to design rationale of the product and the developed tooling is required. Design rationale provides an explanation of why an artifact is designed in the way it is, including statements (textual, numerical or geometrical), argumentations, and decisions. Since design rationale is composed of information scattered all across the company's repositories in different formats (e.g. in type of a geometry, picture, table, and textual document), representing the design rationale is a challenge for many enterprises. In this paper a method is introduced that enables capture, structure and access to design rationale across product design and tooling design. The system enables representing design rationale in formats such as CAD models, spreadsheets, textual formats, and web pages. The method has been examined by developing a prototype system tested in a case company which develops and manufactures customized car accessories, such as roof racks and bike carriers, for different car models. The company develops and manufactures the products as well as the required tooling equipment. The prototype system includes different software commonly used by engineers during designing a product, for the purpose of making it applicable for other companies.

Abstract [en]

Individualized products, resource-smart design and production, and afocus on customer value have been pointed out as three opportunities for Swedishindustry to stay competitive on a globalized market. All these three opportunitiescan be gained by efficient design and manufacture of highly customized products.However, this requires the development and integration of the knowledge-basedenabling technologies of the future as pointed out by The European Factories ofthe Future Research Association (EFFRA). Highly custom engineered productsrequire an exercising of a very rich and diverse knowledge base about the products,their production and the required resources for design and manufacture. Thedevelopment and implementation of systems for automated design and productionpreparation of customized products is a significant investment in time and money.However, our experience from industry indicates that significant efforts arerequired to introduce and align these kinds of systems with existing operations,legacy systems and overall state of practice. In this paper, support for systemdevelopment in literature has been reviewed in combination with a survey on thestate of practice in four companies regarding implementation and management ofautomated systems for custom engineered products. A gap has been identified anda set of areas for further research are outlined.
