Methodology for Certification-Compliant Effect-Chain Modeling

The success of engineering complex technical systems is determined by meeting customer requirements and institutional regulations. One example relevant to the automobile industry United Nations Economic Commission Europe (UN ECE), which specifies homologation series requires proof traceability. required traceability can be achieved modeling system artifacts their relations in a consistent, seamless model—an effect-chain model. Currently, no in-depth methodology exists support engineers developing certification-compliant models. For this purpose, new for was developed, includes extensions an existing method, suitable models, tools process. evaluation purposes, applicability proven based on experience more than 300 workshops at automotive OEM supplier. following case chosen demonstrate applicability: development window lifter that has meet demands UN ECE Regulations R156 R21. Results indicate multiple benefits supporting with effect chains. Three are goal-oriented reduce necessary capacity, increasing model quality applying information criteria, potential costs through automatable analyses changes. Further, companies other industries will benefit from increased capabilities used architecture comply regulations such as ASPICE or ISO 26262.
