This study aims to investigate the different management policies of multi-reservoir systems and their impact on the demand supply and hydropower generation in Great Karun River basin. For this purpose, the semi-distributed simulation-optimization  model of the Great Karun River basin is developed. Also, the multi-objective particle swarm optimization algorithm is applied to optimize the develop...

The importance of drug as a valuable export product in the global economy becomes more clear every day. Understanding the problems of exports and factors affecting it, can be an important step to keep Iran’s position in the world markets and further export development of this product.In this study, Iranian pharmaceutical exports’ supply and demand functions were calculated using co-integration ...

Supply chain management is taken into account as an inseparable component in satisfying customers' requirements. This paper deals with the distribution network design (DND) problem which is a critical issue in achieving supply chain accomplishments. A capable DND can guarantee the success of the entire network performance. However, there are many factors that can cause fluctuations in input dat...

Background & Aim: Physicians as human capital and resources are one of the main components of health production. The imbalance of physician supply and demand affects the health and economics. Therefore, this study aimed to estimate and forecast the supply and demand of physician working in Iranian medical universities. Materials and Methods: This a descriptive-analytical and applied study was ...

Decision support tools are increasingly used in operations where key decision inputs such as demand, quality, or costs are uncertain. Often such uncertainties are modeled with probability distributions, but very little attention is given to the shape of the distributions. For example, state-of-the-art planning systems have weak, if any, capabilities to account for the distribution shape. We con...

Pakistan's population welfare program was established with the assumption that many people in Pakistan did not use contraception because they had no access to an available supply of contraceptive methods. Were they provided contraceptives, widespread latent demand would translate into effective demand, and the contraceptive supplies would be used. The population welfare program since its ince...

(2012): Agent-based simulations for advanced supply chain planning and scheduling: The FAMASS methodological framework for requirements analysis, This article may be used for research, teaching, and private study purposes. Any substantial or systematic reproduction, redistribution, reselling, loan, sub-licensing, systematic supply, or distribution in any form to anyone is expressly forbidden. T...

A design and planning approach is proposed for addressing general multi-period, multi-product closedloop supply chains (CLSCs), structured as a 10-layer network (5 forward plus 5 reverse flows), with uncertain levels in the amount of raw material supplies and customer demands. The consideration of a multi-period setting leads to a multi-stage stochastic programming problem, which is handled by ...

As a review of game theoretic approach to optimize the logistic costs with the objective of modeling interactions among players in a basic supply chain, this paper focuses on a single channel, two-echelon supply chain with a retailer and his supplier of a one-product where careful attention is given to information sharing in general and demand forecasting in particular. Therefore, in the indust...
