An optimization model is proposed to redesign the supply chain of spare part delivery under demand uncertainty in a specified planning horizon. Long term decisions involve new installations, expansions and elimination of warehouses handling multiple products. It is considered which warehouses should be used as repair work-shops to store, repair and deliver used units to customers. Tactical plan...

Capacity planning is a major challenge for service providers facing volatile demand. Inefficiencies result from idle capacity or lost revenue caused by peak loads. Concerning IT-driven services, recent technological developments offering dynamic integration and information capabilities may help. They enable an on-demand exchange of excess capacity between business partners and create value thro...

The manufacturing of the automobile industry is highly dependent on market demand. Therefore, impact changes in demand supply chain worthy attention. This article considers application flexible production management to industry. Simulation analysis research analyzes overall differences behavior different entities chain. By examining possible consequences these impacts, it provides targeted opti...

In this article, the design of a Supply Chain Network (SCN) consisting of several suppliers, production plants, distribution centers and retailers, is considered. Demands of retailers are considered stochastic parameters, so we generate amounts of data via simulation to extract a few demand scenarios. Then a mixed integer two-stage programming model is developed to optimize simultaneously two o...

In supply chains, forecasting is an important determinant of operational performance, although there have been few studies that have selected forecasting methods on that basis. This paper is a case study of forecasting method selection for a global manufacturer of lubricants and fuel additives, products usually classified as specialty chemicals. We model the supply chain using actual demand dat...

The major problems that manufacturers and marketers face when using the Internet to manage the global value chain are (1) cannibalization of normal traditional channels sales by Internet based sales; (2) overselling supply, production, and distribution capacities due to the lack of salesperson involvement to apply knowledge about these capacities; (3) misinterpretation of the permanency of the ...

Blood banking systems in the United States over the past decade have been faced with a volatile demand for blood, specifically, a decrease in demand for red blood cells, for a variety of reasons. This change in the blood supply chain landscape, accompanied by an increasing emphasis on cost efficiency, is a driver of Mergers & Acquisitions between blood banks. In this paper, we first present sup...

Supply chain managers are trying to maximize the profitable operation of their manufacturing and distribution supply chain, but due to global competition in process industries and complexities of the supply chain processes together with large computational times, it has made optimization of supply chain management (SCM) quite difficult. Recently, Knowledge management (KM) is a new important inf...
