Subproject D1: Support for shaping PSS innovation processes through diagnosis and resolution of inconsistencies be-tween models from different domains

Goal of the integrative subproject D1 is to improve the management of cycles – especially development and change cycles – by identifying and resolving faults early during PSS innovation cycles. Therefore, sub-project D1 develops an approach, which on the one hand integrates the different heterogeneous models that are involved in the PSS innovation process and on the other hand enables a diagnosis and resolution of inconsistencies between these models through appropriate processing mechanisms. Thus, unnecessary iterations during the PSS innovation process can be avoided and, by that, time and money during PSS development can be saved.

Motivation

  • Heterogeneous views on PSS within the innovation process
    • Aspects: Product, service, production, sociotechnical environment, etc.
    • Levels of abstraction: e. g. during requirements elicitation, idea generation
    • Formalisms: e. g. textual specifications (informal), graphical models during development (semi-formal), simulation models for verification (formal)
  • Semantic relations between models
  • Cyclic changes in heterogeneous model landscapes of PSS innovation processes
  • Potential inconsistencies between views
    • Logical contradictions: e. g. as a result of redundant specifications, mathematical contradictions
    • Over- and under specifications: e. g. as a result of logical contradictions
    • Theories and (physical) laws: e. g. mass and energy conservation
    • Standards and norms: e. g. violations of guidelines
    • Heuristics and company-/project-specific agreements: e. g. violation of naming conventions
  • Result: Potentially labor-intensive errors during PSS innovation process

Results of funding period 2

  • Start-up funding within CRC 768 based on the cooperation of subprojects A4, A6 and C2 together with Prof. C.J.J. Paredis (Georgia Institute of Technology)
    • Basis: PSS integration framework
    • Models of interest: Structural models of mechatronic manufacturing systems
    • Aim: Identification of inconsistencies
  • Central results of the start-up funding
    • Graph-based representation of models using the Resource Description Framework
    • Specification of inconsistencies as graph patterns using the SPARQL Protocol and RDF Query Language
    • Specification of semantic relations through semantic mediation of domain-specific models
  • Basis for inconsistency management in funding period 3

Prospective results of funding period 3

  • Knowledge-based system for managing inconsistencies
    • Representation of domain knowledge in a central knowledge base
    • Processing of the modeled knowledge by means of reasoning mechansisms
  • Key aspects of subproject D1
    • Representational formalism: Domain-spanning representation of the modeled knowledge
    • Reasoning mechanisms: Diagnosis and resolution of inconsistencies
    • Supporting methodology: Recommended actions, design guidelinges and visualization concept
