MULTI-OBJECTIVE PRODUCTION PLANNING PROBLEM FOR A LOCK INDUSTRY: A CASE STUDY AND MATHEMATICAL ANALYSIS

Abstract

This case study develops a multi-objective production planning for a lock industry. The specific lock industry,i.e. Mezia lock industry produces various types of locks during the production run. The main objective of the firm is to minimize the production cost as well as profit maximization with consideration of the realistic constraints. This type of model formulated by considering the input information collected from the decision-maker. However, in many cases, it has been seen that the input information provided by the manufacturer is not precisely known. Formulation of the model has been solved by the Lingo 16.0 under a certain limitation, which can be further explored.
