Obsolescence Management with MCDM Case Study

The decision to refresh design of a sustainment dominated systems such as military, nuclear, transportation system is not purely a cost minimization single objective problem, instead, multiple objectives such as maximizing efficiency and security must also be considered. Multiple objectives create a pareto optimal solution set which constitutes non-dominated solutions for decision makers to select one based on his/her priorities. The research hypothesis is that the quality of pareto optimal solutions sets deteriorates over time and the point where the quality reaches a minimum point that reflects the risk appetite of an organization or decision-maker, is the point to refresh the design of a sustainment dominated system. We have demonstrated the validity of this hypothesis in a case study. This data set belongs to a case study.
