Aggregate planning is an important method in supply chain management to increase competition and customer services in the market. Supply chain management information systems are the information systems between companies that employ information and communication technology to arrange information inside and among the participator of a supply chain such as clients, sellers, providers, and distributors. The goal of this research is to designing and developing an information system, for implementing aggregate planning methodology; to make decision about production, outsourcing, inventory, and...

The purpose of this study is to investigate the effects of an external heat flux applied to a bifurcated artery which surrounded by the human tissue during thermal therapy. Two different 2D models have simulated, first the bifurcated artery, and second the stenosed bifurcated artery with two symmetrical stenosis. This study helps a lot to determinate the principal data for achieving the goal of experimental simulation. Three different external heat fluxes, three different durations and different physical properties have been investigated. Non-dimensional blood and tissue temperatures were...

In this book, a mixed integer programming (MIP) model formulation has been proposed to find out the optimum order quantity, optimum order time, and the minimum total cost of purchasing, ordering, and holding over the predefined planning horizon. Several forecasting techniques have been used to determine future demands. As in reality the price is not always stable, the prices of the parts were estimated. The companies also need an adequate amount of safety stock on hand to avoid stock-outs due to the uncertainty in demand; therefore, optimal safety stock for each part was calculated based on...
