Abstract
Sustainability has become of great interest in many fields, especially in production systems due to the continual increase in the scarcity of raw materials and environmental awareness. Recent literature has given significant attention to considering the three sustainability pillars (i.e., environmental, economic, and social sustainability) in solving production planning problems. Therefore, the present study conducts a review of the literature on sustainable production planning to analyze the relationships among different production planning problems (e.g., scheduling, lot sizing, aggregate planning, etc.) and the three sustainability pillars. In addition, we analyze the identified studies based on the indicators that define each pillar. The results show that the literature most frequently addresses production scheduling problems while it lacks studies on aggregate production planning problems that consider the sustainability pillars. In addition, there is a growing trend towards obtaining integrated solutions of different planning problems, e.g., combining production planning problems with maintenance planning or energy planning. Additionally, around 45% of the identified studies considered the integration of the economic and the environmental pillars in different production planning problems. In addition, energy consumption and greenhouse gas emissions are the most frequent sustainability indicators considered in the literature, while less attention has been given to social indicators. Another issue is the low number of studies that have considered all three sustainability pillars simultaneously. The finidings highlight the need for more future research towards holistic sustainable production planning approaches.
Highlights
Production planning is the process of making a set of decisions or a plan to ensure the correct and efficient flow of production processes according to specific objectives
The remainder of this paper is organized as follows: In Section 2, we present an overview of the different production planning problems and explain the sustainability pillars used to classify the relevant studies; in Section 3, we discuss the review methodology; in Section 4, we present the results; in Section 5, we suggest implications for future research; in Section 6, we present the conclusions
Each article is assigned to its corresponding sustainability indicator and production planning problem used
Summary
Production planning is the process of making a set of decisions or a plan to ensure the correct and efficient flow of production processes according to specific objectives. Due to increasing the world population and production capacities, the resources of our planet are excessively consumed Methods to safeguard these resources from vanishing are necessarily required [6,7]. Et al [18] covered the period from 2008 to 2014 and considered only one production planning problem, i.e., scheduling They found that the link between tactical and operational levels wasvery neglected and further studies areneeded, especially for planning activities. They reported an increase in the research of energy-oriented production planning approaches They concluded that most articles mainly focused on job allocation and sequencing more than any other planning problem. The existing literature lacks a holistic review study that analyzes the relationships among different production planning problems (e.g., scheduling, lot sizing, aggregate planning, etc.) and 3Ps of sustainability. The present review study focuses on all production planning problems and considers all pillars of sustainability, i.e., economic, environmental, and social sustainability
