(An) interactive multiple objective decision making in production planning with three participants

Abstract

Up to the present, the evaluation measure to appreciate the production planning alternatives has been built by estimating the cost for each major factor although it may be a difficult task. And the different viewpoints between participants, especially between stockiest and supplier, which may be occurred frequently in production management, have not been considered. This study suggests a production planning model with multiple objectives and an interactive MODM algorithm by creating each major factor as an objective. Doing so, makes up for the weakness of existing ways and gives a more flexible decision. The suggested model provides with the individual consideration of the conflicting multiple objectives without resorting to a priory trade-off decision through subjective cost estimation. The problem can be solved through the weighting vectors generated by the preference structures of stockiest and supplier interactively. The concept of equity is used in order to guarantee the reasonable distribution of group utility in determining the individual relative weight of stockiest and supplier. Top decision maker participates in generating a weighting vector as an arbitrator. This study encompasses the reality of the model and the decision process in production planning problem.
