Abstract

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.

Highlights

In industrial sectors, energy efficiency is the ratio between the energy required to produce and the total energy consumed by the plant
We focus on research that considers energy in terms of consumption, especially the 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
Conclusion and Perspective is paper aims to address this gap by incorporating energy consumption as an explicit criterion in shop floor scheduling

Summary

Introduction

Energy efficiency is the ratio between the energy required to produce and the total energy consumed by the plant. Increasing energy efficiency is a very important avenue for financial savings in industry. This energy is responsible for almost 80% of greenhouse gas emissions. Is is the basis for the 20/20/20 strategy, which provides for a 20% reduction in greenhouse gases, an increase in the share of renewable energies to 20%, and a 20% reduction in energy consumption by 2020 [1]. It potentially becomes a vital necessity for the well being of our communities and our economy. In parallel with the process of energy production and consumption, an enormous amount of greenhouse gases have been and will be emitted into the atmosphere
