چکیده:
In this research, a real case study of the natural gas supply chain has been investi-gated. Using concepts related to natural gas industry and the relations among the components of gas and oil wells, refineries, storage tanks, dispatching, transmission and distribution network, a seven-level supply chain has been offered and presented schematically. The aim of this paper is to optimize a case study using a multi-objective and multi-period model considering maximize the total revenue, minimize the economic and environmental costs, minimize the penalty per underutilized capac-ity and maximize the service level. A small-sized model was verified and solved using an improved augmented ε-constraint algorithm to generate Pareto optimal solutions and assessed trade-offs among objectives in order to help decision makers make an optimal decision. To the best of our knowledge, this is the first study that presents a multi-objective optimization model for the resilience and sustainable supply chain.

com A Multi-Objective Optimization Model for the Resilience and Sustainable Supply Chain: A Case Study Mohammad Reza Zamanian a, Ehsan Sadeh a,*, Zeinolabedin Amini Sabegh a and Reza Ehtesham Rasi b a Department of management, college of human science, Saveh Branch, Islamic Azad University, Saveh, Iran b Department of Industrial Management, Qazvin Branch, Islamic Azad University, Qazvin, Iran Abstract In this research, a real case study of the natural gas supply chain has been investigated.
Given that a number of researches conducted in recent years on the dimensions of sustainability and r esilience in some levels of the supply chain, some dimensions of resilience such as the service level, or adequate inventory on the network and facilities and decreasing penalty per underutilized capacity, or recovery, and some dimensions of sustainability such as the environmental or social costs of greenhouse gas emissions, economic or supply chain costs, and total revenue earned in the consumption nodes at all levels and components of the natural gas supply chain are investigated in the present study and provided as the contribution of this research while considering the trade-offs among them.
Proposed Multi-Objective Model This natural gas supply chain is formulated in terms of the dimensions of sustainability such as the environmental and economic costs and revenue and resilience such as the service level and penalty per underutilized capacity, or recovery.
This study presents a multi-objective optimization model for the resilience and sustainable natural gas supply chain in the Iranian gas industry, including maximizing the total revenue and service level and minimizing the economic costs, environmental costs and penalty per underutilized capacity in the consumption nodes at all levels and components of the natural gas supply chain in a one-year time horizon, in order to assess trade-offs among them and advise decision makers on the natural gas supply chain management.
