Decision making over the production system life cycle: MOORA method

Abstract

Decisions in robust and flexible production systems are made in an environment often characterized by complexity, need for flexibility, and inclusion of a decision-maker's subjectivity. Typically in production system life cycle, decisions on the product design, facility location, facility layout, supplier, material, technology, and so forth has to be made in an efficient and timely manner. These decisions are more complex as the decision makers have to assess a wide range of alternatives based on a set of conflicting criteria. In this paper, application of multi-objective optimization on the basis of ratio analysis approach is explored to solve such type of decision making problems. Moreover performance of the reference point approach is also tested for the considered decision making problems. © 2013 The Society for Reliability Engineering, Quality and Operations Management (SREQOM), India and The Division of Operation and Maintenance, Lulea University of Technology, Sweden.
