Advanced multi-objective searching method to solve rescheduling problems of discrete production processes

Abstract

The paper summarizes the features of rescheduling problems of the discrete production processes and describes a new extended solving method. The purpose of the rescheduling is to manage the unexpected events occurred during the manufacturing. The rescheduling process creates a modified version of the predictive schedule for a given time horizon. It is required that the performance indicators take up suitable values and the deviation from the original schedule should be as small as possible. To solve this problem, we propose an advanced multi-objective searching method by using locking techniques.
