Multi-objective Process and Production Planning Integration in Reconfigurable Manufacturing Environment: Augmented E-constraint Based Approach
Résumé
Nowadays, manufacturing systems should be cost-effective and environmentally friendly to cope with various challenges in today's competitive markets. Furthermore, being cost-effective needs to optimize the behaviour and functionality of the production system and being environmentally friendly requires to reduce the amount of harmful gasses emitted in the working area. In this context, reconfigurable manufacturing systems (RMSs) have emerged to fulfil these requirements. RMS is one of the latest manufacturing paradigms, where machines components, software or material handling units can be added, removed, modified or interchanged as needed and when imposed by the necessity to react and respond rapidly and cost-effectively to changing. In this paper, a multi-objective multi-product process and production planning problem in a sustainable reconfigurable manufacturing environment is considered. The cost function and three pillars of sustainability functions such as social, environmental, and economical are introduced and optimized. Moreover, an augmented ε-constraint method is proposed to solve the problem. Finally, an illustrative numerical example is presented to show the validity of the approach.
