Deciding Between Independence and Coalition, in an Three Echelon Supply Chain
By considering the role and importance of supply chain management, this concept faced with many challenges and problems. Although there is no explanation of a comprehensive model for supply chain issues, a review of theoretical issues in this field, indicates that information systems, marketing, financial management, logistical and organizational relations, matters of interest to researchers in this field. The objective of supply chain management is improvement of various activities and components of a supply chain to increase overall supply chain system. Many contradictions between the components and different levels in order to achieve the overall objectives of the supply chain have been observed, and these disorders may result by decreased strength and competitiveness of supply chain. The main contradictions that are considered in this paper are related to inventory, pricing and also marketing costs in an unlimited three echelon supply chain. The basics of game theory make it a suitable and reliable tool for solving contradiction situations by considering all levels and players goal. In this paper, finding equilibrium of inventory, pricing and marketing cost of an unlimited three echelon supply chain(SC), consisting of supplier, manufacturer and retailer is considered. K retailer, M manufacturer and S supplier are acting, and different leadership of each level are examined to find the highest payoff for the supply chain.

Optimizing Supplier’s Replenishment Strategy in a Two-Echelon Supply Chain under Stochastic Lead Time
All decisions made by each Supply Chain (SC) member can affect other members’ profitability. Replenishment decisions are among critical decisions within SC. inconsistency between SC members about replenishment decisions leads to a low SC service level. In this paper, a coordination mechanism for coordinating supplier’s replenishment decisions in a two-stage SC is developed. By modeling the ‘aggregate lead time’, the impact of supplier’s lead time uncertainty on SC service level is examined. In the next step, an incentive scheme based on ‘supply participation’ is developed in order to optimize supplier’s replenishment decisions. Based on the proposed model, supplier can benefit from financial assistance from the retailer for purchasing raw material, by re-setting its reorder point and also replenishment size on the optimal values. Numerical experiments show that: (1) In presence of uncertain supplier lead time, coordinating supplier replenishment decisions is beneficial, and (2) The proposed coordination model is capable of achieving channel coordination. Previous literature in this field have focused on coordinating downstream replenishment decisions while in this paper coordinating upstream replenishment decisions are investigated.

The Concept of World-Class Manufacturing from Modernistic and Postmodernistic Prespective
In recent years٫ world class manufacturing concept is considered as a phenomenon that leading organizations are required to implement and use its criteria. On the other hand, with the transition from the era of modernism٫ the contemporary world get affected on the new thoughts and ideas that are presented in the form of postmodernism. In this vicissitudinous path, reviewing phenomenon that pass through both the thoughts is very important. Therefore٫ the purpose of this paper is to examine the concept of world class manufacturing from the prespective of modernism and post-modernism. The research method is descriptive٫ and to gather information library study method was used, and also to collect the required data a questionnaire is utilized. This paper٫ first reviews the concepts of modernism٫ post-modernism and world class manufacturing. The phenomenon of world class manufacturing is discussed from the both perspective. Finally modernistic and postmodernistic indicators and suggestions of WCM concept are offered.

Analysis of University-Industry Relation in Higher Education Policies of the Fifth Development Plan using System Dynamics
Recently, In Spite of the tremendous progress of Iran, the Scientific outputs of a variety of disciplines has not so extended to application; a subject that affected by the role of Government as principal role player in the public sector. Higher Education Policies are among important artifacts of government roles in this field, which perception of their Causal relation and loops is prerequisite for their Implementation. This paper is going to analyze the University-Industry relation in the Fifth Development Plan Using System Dynamics. So the Modeling Process has based on Expert consensus through Delphi Method. The Results show that regarding Time Delays, Reinforcing and Balancing loops has so influence on plans cohesion. Finally based on simulation of critical variables, some suggestions have been presented to Improvement of policies.

A Model for the Identification and Evaluation of Locations of Agencies and Branches of Service – Industrial Companies
One of the factors affecting the efficiency and effectiveness of a bank is its location. An optimal location for the establishment of a branch can pave the way to meet other bank objectives. The study investigates the location of bank branches in terms of both subjective and objective factors. The research community is the third supervision departemnt of Saderat Bank in south Tehran. The study tries to answer three questions. The subjective factors of 8 and 4 were used to assess the location of the existing branches. To obtain the location weights, The AHP paired comparison was applied. Subjective criteria were assessed through geometric mean of the sample by integrating member comments. The medal Brown-Jason branches was applied to prioritize the integration and combination of subjective and objective factors. The study concluded that the bank image will determine the quality and quantity of bank branches .So it can be stated that a branch which is located in the right and optimal place is more profitable.

The Analysis of Iran Cell Phone Market by Using System Dynamics Approach
phone) market due to the activation of more than one operator. Before 2006, with the appearance of “Iran cell”, Iran mobile telephone had a complete monopoly but after the entrance of the second operator, the competition was formed in this market and the result was the increase of variety in the service of the products, the improvement of network quality, the attempt to keep the users and attracting more share of the market.Here, Iran cell phone market was simulated during 2001 to 2025 by System Dynamics approach. The current study aimed to make an operational model and determine various scenarios for "Hamrah Aval" based on the existing competition market to 2025. In the current study four key variables, number of users, income, costs and capital were simulated. The overall results of the study showed that by continuing the present trend of Cell phone market in Iran, "Hamrah Aval" company is going to lose 10% of market share by 2025. But the change in this trend is possible via various scenarios as creating new infrastructures and increasing the covered regions or the change in the service price.

A Model for Forecasting the Product Demand in Tile and Ceramic Industry
Forecasting the product demand is one of the most important activities of every organization for planning the sale and finally making a comprehensive plan. It in fact determines the amount of the activities an organization carries out in the future and also provides the managers with a clear understanding of the amount and quality of the respected activities. In this article, a model based on Artificial Intelligence and Data Mining algorithms is proposed for predicting the amount of sale in tile and ceramic industry. The proposed model is a hybrid model consisting of dimensionality reduction, clustering and forecasting. In order to construct the model, this research uses independent component analysis, Manifold learning, K-means clustering and support vector regression. The present research studies 50 cases of Irana Tile Company's past 3 years of monthly sales. Because of the decrease in generic and sampling errors, the results obtained from this model show a superior precision compared to other traditional forecasting methods.
