design of a logistics network in proper way provides a proper platform for efficient and effective supply chain management. this paper studies a multi-period, multi echelon and multi-product integrated forward-reverse logistics network under uncertainty. first, an efficient complex mixed-integer linear programming (milp) model by considering some real-world assumptions is developed for the inte...

Assessment and selection of suppliers are two most important tasks in the purchasing part in supply chain management. Supplier selection can be considered to be a single or multi-objective problem. From another point of view, it can be a single or multi-sourcing problem. In this paper, an integrated AHP and Fuzzy TOPSIS model is proposed to solve the supplier selection problem. This model makes...

This article uses seasonal integration and co integration techniques to test the hypothesis of neutrality of money, using data from the Iranian economy. Seasonal data for the three variables of money supply, output and prices show that (increase in) money supply and the price level are co integrated at zero frequency, but one does not see such a relationship between (increase in) money supply a...

A new class of integrated power devices has been developed to simplify embedded dc-dc power supply designs. The paper includes comparison with existing discrete/co-package solutions and a new methodology that has been developed in how integrated devices are being designed, specified, tested and qualified. The paper also details how treating integrated devices as power supply modules instead of ...

The latter part of the 20 Century saw the lean production paradigm positively impact many market sectors ranging from automotive through to construction. In particular there is much evidence to suggest that level scheduling combined with the elimination of muda has successfully delivered a wide range of products to those markets where cost is the primary order winning criteria. However, there a...

--In this paper, we consider an integrated inventory model with one vendor and multiple retailers. In this three-tier supply chain system, the vendor purchases raw material produces into finished products, and delivers finished products to the retailers. We assume that the production (at the vendor) and the replenishment (at all the retailers) of the finished products share the common cycle tim...

We present an analytical tool to identify the optimal supply chain design and resource allocation that integrates supply chain planning with information from management accounting. Using costing data based on Time-Driven Activity Based Costing techniques, an optimization model determines the most beneficial route to market (i.e., with the lowest cost-to-serve) given the resource constraints in ...
