Optimization of Multi-tool Cutting Modes in Multi-item Batch Manufacturing System

Multi-echelon Exchangeable-item Repair System Optimization

We consider an M/G/∞ exchangeable-item repair system with spares and ample servers to which arriving customers bring failed items for repair. The system comprises a multi-item-type, multiechelon system in which failed items may be either repaired at the first echelon or sent for repair in higher echelons. To decrease the average waiting time of a random customer, managers can invest in multiple...

OPTIMIZATION OF MULTI PERIOD - MULTI LOCATION CONSTRUCTION PROJECTS CONSIDERING RESOURCE POOL AND BATCH ORDERING

During the past two decades, some industries have been moving towards project-centered systems in many modern countries. Therefore, managing simultaneous projects with considering the limitations in resources, equipment and manpower is very crucial. In the real world, project-based organizations are always facing with two main important features. First, the construction projects are decentraliz...

Role of batch size in scheduling optimization of flexible manufacturing system using genetic algorithm

Flexible manufacturing system (FMS) readily addresses the dynamic needs of the customers in terms of variety and quality. At present, there is a need to produce a wide range of quality products in limited time span. On-time delivery of customers’ orders is critical in make-to-order (MTO) manufacturing systems. The completion time of the orders depends on several factors including arrival rate, ...
