closed-loop supply chain network design is a critical issue due to its impact on both economic and environmental performances of the supply chain. in this paper, we address the problem of designing a multi-echelon, multi-product and capacitated closed-loop supply chain network. first, a mixed-integer linear programming formulation is developed to maximize the total profit. the main contribution...
In the current design of reverse supply chain, several performance indicators must be considered and treated attentively. At this strategic level of the conception and to ensure a sustainable closed loop green supply chain, many qualitative as well quantitative criteria are taken into consideration with an environmental respect. Since the location allocation study persists as one of the most im...
In this study, a bi-objective model for integrated planning of production-distribution in a multi-level supply chain network with multiple product types and multi time periods is presented. The supply chain network including manufacturers, distribution centers, retailers and final customers is proposed. The proposed model minimizes the total supply chain costs and transforming time of products ...
Background and objective After a large-scale natural disaster, the lack of supply and unfair distribution of relief items can cause high human casualties and hinder the function of the humanitarian supply chain. Therefore, this study aims to present a framework based on mathematical modeling for the proper distribution of relief items among the affected areas in Tehran Method In this study, mat...
In this paper, a multi-objective multi-period multi-product supply chain network design problem is introduced. This problem is modeled using a multi-objective mixed integer mathematical programming. The objectives are maximizing the total profit of logistics, maximizing service level, and minimizing inconsistency of operations. Several sets of constraints are considered to handle the real situa...
Supply Chain Operations Reference (SCOR) model is developed and maintained by the Supply Chain Council (SCC). The model is a reference model which can be utilized to map benchmark and improve the supply chain operations. SCOR model provides companies with a basic process modeling tool, an extensive benchmark database by defining a set of supply chain metrics. This paper explains the process and...
Decentralized supply chain management is found to be significantly relevant in today’s competitive markets. Production and distribution planning is posed as an important optimization problem in supply chain networks. Here, we propose a multi-period decentralized supply chain network model with uncertainty. The imprecision related to uncertain parameters like demand and price of the final produc...
In this study, tactical decisions considering the material and financial flows in a supply chain have been made. To achieve these aims and some effective solutions, a multi-objective mathematical model proposed for an integrated supply chain master planning problem. The multi-product, multi-period and capacitated supply chain network has three objective functions. Two first objective functions ...
چکیده در این مقاله، برای افزایش کارایی شبکه زنجیره تأمین پیشنهادی، مدل چنددورهای و چندمحصولی را با اهداف چندگانه به طور هم زمان درنظر گرفته ایم. برای طراحی شبکه، از مدل برنامهریزی ریاضی چندهدفه عدد صحیح مختلط استفاده کردیم و اهداف مسئله شامل حداقل کردن هزینه تولید، کاهش زمان ارسال محصولات و افزایش قابلیت اطمینان زنجیره تأمین است. برای حل مدل و ارائه جوابهای نامغلوب، از روش اپسیلون محدو...
