Green Scheduling of Jobs and Flexible Periods of Maintenance in a Two-Machine Flowshop to Minimize Makespan, a Measure of Service Level and Total Energy Consumption

الملخص EN

The success of an industry today depends on its ability to innovate.

In terms of energy performance, this innovation is reflected in the ability of manufacturers to implement new solutions or technologies that enable better energy management.

In this regard, this paper aims to address this gap by incorporating energy consumption as an explicit criterion in flowshop scheduling of jobs and flexible preventive maintenance.

Leveraging the variable speed of machining operations leading to different energy consumption levels, we explore the potential for energy saving in manufacturing.

We develop a mixed integer linear multiobjective optimization model for minimizing the makespan and the total energy consumption.

In the literature, no papers considering both production scheduling and flexible periods of maintenance with minimizing both objective the total of energy consumption in flowshop and makespan.

The performance of the proposed mixed binary integer programming model is evaluated based on the exact method of branch and bound algorithm.

A study of the results proved the performance of the model developed.
