Operations scheduling for waste minimization: A review

This article proposes a review on waste minimization at the operational level of production planning. After defining the research scope and the concept of waste minimization through scheduling, the state-of-the-art is presented. A classification based on environmental and scheduling criteria is proposed, which details the various types of scheduling problems encountered and groups them into different categories. Results show that despite having developed in the recent years, literature on waste minimizing scheduling remains scarce and lacks a unified terminology. While research on energy efficient scheduling has garnered a lot of attention, improving resource efficiency and reducing waste generation is also an important step towards a greener production. Thus, research perspectives for the inclusion of waste reduction concerns in scheduling are proposed based on the analysis of the literature classification. (C) 2018 Elsevier Ltd. All rights reserved.
