A New Approach to Reducing Search Space and Increasing Efficiency in Simulation Optimization Problems via the Fuzzy-DEA-BCC

Abstract EN

The development of discrete-event simulation software was one of the most successful interfaces in operational research with computation.

As a result, research has been focused on the development of new methods and algorithms with the purpose of increasing simulation optimization efficiency and reliability.

This study aims to define optimum variation intervals for each decision variable through a proposed approach which combines the data envelopment analysis with the Fuzzy logic (Fuzzy-DEA-BCC), seeking to improve the decision-making units’ distinction in the face of uncertainty.

In this study, Taguchi’s orthogonal arrays were used to generate the necessary quantity of DMUs, and the output variables were generated by the simulation.

Two study objects were utilized as examples of mono- and multiobjective problems.

Results confirmed the reliability and applicability of the proposed method, as it enabled a significant reduction in search space and computational demand when compared to conventional simulation optimization techniques.
