Solving Multi-Objective Production Scheduling Problems Using a New Approach

Abstract

Most companies use a proactive approach to schedule production orders and jobs at shop floor level. To make a near-optimal schedule for a shop with different types of machines and many operations is a very important but complicated task because of the very large number of alternative solution in the searching space. Advanced scheduling models, good heuristics and fast improving algorithms are required to satisfy constraints and to optimize production performances. The aim of the paper is to outline a new modelling and solving approach connected to discrete production scheduling and rescheduling.
