FORPRO² Subproject 5

(finished) Process-oriented Requirements in Simulation Management

Field of Study


Simulation-oriented requirements engineering, explicit and tacit requirements, reutilization concept


When applied correctly, the simulation of product features and production processes provides significant potential for increasing development efficiency due to early insights and utilization of solely virtual prototypes. However, the individual product developer normally does not have a holistic overview regarding the applied simulation tools' performance. In many cases, he does not conduct simulations himself on a regular basis and is therefore dependent on expert knowledge. This expert knowledge largely exists in the organization itself, however, its preparation, provision and utilization provides significant room for improvement. Consequently, simulations are often used late, too seldom, not at the deal time, or incorrectly which can cause unnecessary iterations or waste of resources.


Reutilizing product requirements and reducing redundant process steps in product development, which come along with repeatedly identifying requirements, provide great potential savings. Subproject 5 therefore aims at supporting the elicitation, documentation and provision of context and process knowledge in the simulation phases. Therefore, explicit as well as tacit requirements between the construction and simulation department are to be systematically identified, structured and implemented in a knowledge base. Moreover, know-how and competences and their relation to technical requirements will be depicted. Finally, those simulation requirements will be made available for future reutilization in other development projects. This way, iterations caused by undefined requirements, lacking communication and/or deficient documentation can be reduced and thus development time can be shortened.


In order to identify needs and potential for improvement when dealing with simulation requirements, first, the current situation regarding simulation-oriented requirements engineering in industry will be surveyed with the help of semi-structured interviews. Topics such as requirements elicitation and documentation, reutilization of requirements, associated simulation know-how, and communication between the construction and simulation department will be addressed. Based on these findings, critical domains will be identified and prioritized by comparing current problem areas, which could be determined by interviewing partner companies, with the corresponding improvement potential within simulation-oriented system will be characterized by determining those elements which shall be documented in the course of the requirements elicitation. Finally, the target system, consisting of a reutilization concept at its heart, will be developed. Here, version control will be implemented and selection of requirements which are needed for a specific development situation out of a set of data will be enabled.
