In the present day scenario of industrial competition, supply chain management seeks to synchronize a firm’s processes and those of its suppliers to match the flow of materials, services and information with customer demand. It involves the coordination of key processes in the firm such as order placement, order fulfillment and purchasing which are supported by marketing, finance, engineering, ...

in the present study, water allocation of latian dam between agricultural products was evaluated by using inexact two-stage optimization model and the final results were compared to a fuzzy interval. data were collected from the regional water and agricultural organization of tehran province for 1991 to 2009 years. the results showed that by using interval fuzzy programming, 63%, 69%, 49% and 3...

In the first part of the dissertation, we focus on the retailer's problem of forecasting demand for products in a category (including those that they have never carried before), optimizing the selected assortment, and customizing the assortment by store to maximize chain-wide revenues or profits. We develop algorithms for demand forecasting and assortment optimization, and demonstrate their use...

Argument for Interdisciplinarity in economic education: society, as a whole, needs education to know whether the “social products” are good. We may discuss about a lot of social needs or problems. Solving those means the development and implementation of educational programs. Therefore, a program of education, which includes, among other, the economic education, irrespective of its level, can b...

Coordination is very important in supply chain management and it is one of the main factors in supply chain profitability. Bullwhip effect is one of the basic obstacles to achieve coordination in supply chains and reduction of this phenomenon has an important role in supply chain harmony. The other side, costs of supply chain can be mitigated and customer service level can be increased by reduc...

the revenue management concept and techniques are applied to model the coordination of supply chain elements. the fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. the output of the supply chain can be various products and thus it is measured in terms of ...

We propose a general methodology based on robust optimization to address the problem of optimally controlling a supply chain subject to stochastic demand in discrete time. This problem has been studied in the past using dynamic programming, which suffers from dimensionality problems and assumes full knowledge of the demand distribution. The proposed approach takes into account the uncertainty o...

C often face nonstationary demand due to product life cycles and seasonality, and nonstationary demand complicates supply chain managers’ inventory decisions. This paper proposes a simple heuristic for determining stocking levels in a serial inventory system. Unlike the exact optimization algorithm, the heuristic generates a near-optimal solution by solving a series of independent single-stage ...

this paper describes a new method for the evaluation of non-utility generation impacts on preventive-corrective control of power systems. the proposed method relies on a mixed integer nonlinear optimization and is capable of recognizing the effectiveness of demand side preventive-corrective actions. a number of cases are presented to illustrate the consequences of introducing demand side action...

Most real-world projects require material supplies at various stages. Project-driven supply chains (PDSCs) are the combinations of project activities and their supporting material supply chains where the demand for the latter is driven by the material requirement of the former. Material supply decisions (e.g., inventory positioning) and project decisions (e.g., resource planning, project schedu...
