A reverse logistics chain mathematical model for a sustainable production system of perishable goods based on demand optimization

Abstract

Sustainability in the supply chain means pushing the supply chain to focus on social, economic and environmental aspects, and addressing the existing problems in the traditional supply chain. Considering the importance of evaluating supply chain networks, especially in the field of perishable commodities, this paper aimed to design a mathematical model for the reverse supply chain of perishable goods, taking into account the sustainable production system. In this research, four objective functions were considered to maximize profitability and the level of satisfaction with the use of technology, minimize costs and measure environmental impacts. The results of the implementation of the proposed model for a manufacturing company show that objective functions are sensitive to demand, so the change in demand changes the objective functions, in particular the profitability function.

An Insight into Reverse Logistics with a Focus on Collection Systems

“…Moreover, different techniques and methods have been implemented to investigate RLs, including mathematical modeling, case studies, qualitative and quantitative methods, and decision support systems [113,118,[173][174][175]. The upcoming research is mostly focused on including uncertain factors in models.…”

Sustainability assessment in circular inter-firm networks: An integrated framework of industrial ecology and circular supply chain management approaches

“…While these two papers seek to minimise costs and environmental effects (mainly CO 2 emissions) and maximise positive social impacts (mainly jobs created) simultaneously, Metta and Badurdeen (2011) developed a hierarchical MILP model, where the most important objective is the economic one, followed by the environmental and social one in this order. In contrast, some (fuzzy) optimisation models only consider the environmental and economic objectives (Jiao et al, 2018;Mohajeri and Fallah, 2016;Tavakkoli Moghaddam et al, 2019), while one paper adds the analytical hierarchy process (AHP) method for supplier selection to the MILP (Govindan et al, 2017).…”

Sustainable Supply Chain Design for Perishable Products: A Literature Review

“…Patidar et al [33] proposed a mathematical model for the sustainable supply chain structure of the Indian ago-food food supply chain the proposed model is to attain maximum efficiency in the vehicle routing for the collection of products and products flow from farmers to the nearest food hub (market). Tavakkoli-Moghaddam et al [10] developed a mathematical model for the reverse supply chain of perishable products. They implement the model on production company of ready-made foods of meat products.…”

“…Sabouhi et al [27] seeks at maximizing the efficiency of the supplier under consideration. Tavakkoli-Moghaddam et al [10] considered in their function product freshness, product quality. They try to maximize satisfaction in aid of the usage of technology.…”

“…Inventory management of perishable is complex because of customers' demand variability, distribution, lifetime [8,9]. Food, dairy products, pharmaceutical products and blood are main examples for perishable products [10]. The limitation of the shelf life, overproduction, and storage are the main features of perishable products [11].…”
