In this article we present an industrial application of our mathematical model that integrates
planning and scheduling. Our main objective is to concretize our model and compare the
reel results with the theoretical ones. Our application is realized on a conditioning line of
pharmaceutical products at the ECAM EPMI production laboratory. For this reason and to
save time, we used Witness simulation tool. It gives an overall idea of how the line works,
the Makespan of each simulation and it highlights areas for improvement. We looked for
the best resulting sequence which corresponds to the minest Makespan and total production
cost. Then this sequence is applied on the conditioning line of pharmaceutical products for
simulation. On the other hand, we program our mathematical model with the parameters of
the conditioning line under python in version 3.6 and we adopt a simulation/optimization
coupling approach to verify our model.
This paper reports a new multi-item planning and scheduling problem in a job-shop production
system with the consideration of energy consumption. A mixed integer linear programming
is proposed to integrate planning and scheduling with the consideration of energy
aspect. In this study a new operational constraint is considered in the tactical level because
of the huge interest given to energy consumption and its strong link existing with production
system. To evaluate the performance of this model, computational experiments are
presented, and numerical results are given using the software CPLEX and then discussed.
