Event Graphs for Modeling and Evaluating Modern Production Systems
Very few Mathematical Tools are available to study the dynamics of discrete manufacturing systems. Petri Nets, and in particular a special type of Petri Nets called Timed Event Graphs, seem to be of special interest for ...
A Class of Conflict Free Petri Nets Used for Controlling Manufacturing Systems
This paper is devoted to the behavior, evaluation and management of non-cyclic discrete systems in general and manufacturing systems in particular. We introduce a special type of Petri nets called CFIOs (Conflict-Free nets ...
Performance Evaluation of a Hierarchical Production Scheduling Policy for a Single Machine with Earliness and Tardiness
This paper considers the problem of scheduling a given set of jobs on a single machine in order to minimize the total earliness and tardiness costs. The scheduling horizon is divided into elementary periods; jobs have ...
Hierarchical Modeling Approach for Production Planning
Production management problems are complex owing to large dimensionality, wide variety of decisions of varying scope, focus and time-horizon, and disturbances. A hierarchical approach to these problems is a way to address ...
Manufacturing Cell Design Using Simulated Annealing: an Industrial Application
In this paper, we give a brief summary of simulated annealing procedures used to solve combinatorial optimization problems. We then present the manufacturing cell design problem which consists of designing cells of limited ...
