Subproject C2: Future oriented development of PSS with respect to external cycles

In subproject C2 a methodical approach to forecasting of external cycles affecting the product development is drawn up. So, companies and their functional unit development are enabled to react to trends and carry out the design of future robust PSS. For this, existing approaches of scenario planning and strategy definition will be adapted to match the cyclic nature of relevant factors. In addition, methods of control technology are applied to create cyclic future images describing expected cycles. Based on these cyclic visions scenarios and the functional strategy can be defined.

• Decision-making process for PSS planning: Methods for supporting decisions
  • Identifying and weighting decision criteria: checklist for decision criteria, block model for weighting criteria and decisions
  • Compatibility analysis: Checking the compatibility between PSS element within a PSS concept
  • Quantifying uncertainties: Determining uncertainties of PSS elements based on the decision criteria, enables early identification of measures for changes
  • Evaluating quality features: Determining the degree of performance for quality features based on the customer perception
• PSS-Planungsmodell
  • Knowledge basis for the decision process of PSS planning
  • Covers the entire PSS portfolio (requirements, functions, structure of components…)
  • Modularization and support for variant management
  • Consideration of multiple planning horizons (short-term, medium-term, long-term planning)

• Procedure for defining a cycle-aware development strategy
  • Ontology of external influences as a reasonable tool for identifying relevant influences
  • Method for creating future projections of external cycles
  • Defining future images of external cycles as a basis for the development strategy
