Abstract:
A
collaborative product design decision-making method based on the
sensitivity analysis and knowledge reasoning techniques is proposed. The
decision making model and dependence among design tasks and parameters
are described, and three sensitivity analysis scenarios for continuous
design problems and knowledge reasoning and sensitivity analysis
combined method for discrete design problems are detailed presented. The
collaborative decision-making procedure is elaborated. An agent system
that incorporates the working mechanism of expert system and realizes
sensitivity analysis functions is put forward. The method and system are
tested with the design of feed servo system of numerically controlled
machine and coaxial gear reducer, which illustrates that the method is
sensitive to detect and resolve the conflict among design parameters and
tasks, reduce design iterations and improve design decision-making and
collaboration efficiencies.
