Influence Model
An influence model is a formal design-stage artifact that treats system response properties as functions of multiple interacting factors. It explicitly annotates each piece of knowledge with confidence levels and applicability preconditions, making it particularly suited to expressing the complex relationships in CPS scenarios where heterogeneous factors jointly determine system behavior.
Timeline (last 90 days)
An Influence Model is a design-phase artifact used to represent how design elements and environmental factors jointly affect the response properties of a system.
The research demonstrates that simulation evidence can enrich the Influence Model along four dimensions: pruning decisions on participating elements, characterization of interaction features, abstraction of influence functions, and valid scope information.
Pruning decisions on participating elements involve using simulation evidence to determine which design elements have no significant actual impact on system response, thereby simplifying the model.
Valid scope information is used to annotate under what conditions a piece of design knowledge holds, in order to prevent out-of-bounds misuse.
Compared with traditional causal graphs or decision trees, the Influence Model places greater emphasis on multi-factor interactions under uncertainty and explicitly annotates each piece of knowledge with its confidence level and applicable preconditions.
