A Daily Production Planning Model Considering Flexibility of the Production Line Under Uncertainty: A Case Study

Abstract

Due to the change of production processes from mass production mode to mass customization mode, increasing customer knowledge, and the rapid development of communication technology, manufacturing organizations are under increasing pressure from dynamic changes in the business environment. For example, continuous product changes and unexpected changes in demand patterns; therefore, organizations do their best to be more responsive to their customers by having a flexible production plan and taking into account the latest changes and fluctuations in demand. In this paper, using the mathematical model presented and minimizing the company’s costs, we try to obtain the appropriate time and the appropriate amount of production for each product. The presented model considers production capacity constraints, maximum production variety, as well as maintenance and setup times. The problem has been implemented in general algebraic modelling system software according to the home appliance industry’s conditions and information. Finally, the analysis of change in production line flexibility, change in the minimum allowable production of each product, and change in production capacity are examined and appropriate suggestions for improving the situation are presented and reviewed.
