A meta-heuristic approach supported by NSGA-II for the design and plan of supply chain networks considering new product development

Abstract

There are many reasons for the growing interest in developing new product projects for any firm. The most embossed reason is surviving in a highly competitive industry which the customer tastes are changing rapidly. A well-managed supply chain network can provide the most profit for firms due to considering new product development. Along with profit, customer satisfaction and production of new products are goals which lead to a more efficient supply chain. As new products appear in the market, the old products could become obsolete, and then phased out. The most important parameter in a supply chain which considers new and developed products is the time that developed and new products are introduced and old products are phased out. With consideration of the factors noted above, this study proposes to design a tri-objective multi-echelon multiproduct multi-period supply chain model, which incorporates product development and new product production and their effects on supply chain configuration. The supply chain under consideration is assumed to consist of suppliers, manufacturers, distributors and customer groups. In terms of overcoming NP-hardness of the proposed model and in order to solve the complicated problem, a non-dominated sorting genetic algorithm is employed. As there is no benchmark available in the literature, the non-dominated ranking genetic algorithm is developed to validate the results obtained and some test problems are provided to show the applicability of the proposed methodology and evaluate the performance of the algorithms.

Optimization of End-to-end Supply Chain Costs to Maximize Revenue and Profits From Supply Chain Operations

“…The various parameters selected for the purpose of Optimization are pro t, revenue, total operating costs, logistics & transportation costs, information sharing costs. The costs of establishing information sharing system and information security system, manufacturing the nal product (a tire ring), transportation between the supply chain members, opening manufacturing, distribution, collection, and recycling centers, and nally, purchasing the nal product from different members are other costs of the supply chain network [22]. The Pro t in SC operations refers to the overall e ciency of the supply chain.…”

“…Supply chain comprises elements of the business processes, including people, rms, resource, and activities of management and planning. Depending on the features considered for the supply chain, each element has different costs [22]These elements work in synergy in making the product or service from the manufacturer to the nal customer with the help of important stack holders like suppliers, logistics partners, distributors and wholesalers [10] 1.2 End-to-End Supply Chain: End-to-End supply chain encompasses an entire integrated process across the supply chain that include procurement of resources, scheduling, production, and delivery of nal product to the customer zones. Sometimes, End-to-End supply chain also takes care of after-sales services, reverse logistics, etc., depending on the need of the business.…”

Decentralized supply chain network design: monopoly, duopoly and oligopoly competitions under uncertainty

“…In supply chain network design (SCND) physical structure of a network is shaped and has a great impact on SC's overall performance, Simchi-Levi et al (2003) consider SCND as the primary and most important step for decreasing (increasing) the whole cost (profit) of chains. According to SCND literature (e.g., Shen 2007;Meixell and Gargeya 2005;Beamon 1998), great deal of work has been done on monopoly assumption (Altiparmak et al 2006;Torabi and Hassini 2008;Pishvaee and Rabbani 2011;Babazadeh et al 2012;Rao et al 2013;Tavakkoli-Moghaddam et al 2013;Shankar et al 2013;Badri et al 2013;Ö zceylan et al 2014;Vahdani and Mohamadi 2015;Yang et al 2015;Sherafati and Bashiri 2016;Ardalan et al 2016;Keyvanshokooh et al 2016;Ö zceylan et al 2016; Alizadeh Afrouzy et al 2017;Chiadamrong and Piyathanavong 2017;Jeihoonian et al 2017, Varsei andPolyakovskiy 2017). Although there are many examples of SC competition in real world including maritime shipping, automotive industry, online bookstores, pharmaceutical SC and retail industry Farahani et al (2014), it is highly ignored in the literature.…”
