Supply chain management including integrated decision making process during supply chain from row material supplier to product consumption by final customer. This process includes three kind of main decision of supply, production and distribution in strategic, tactical and operational levels. Supplier selection is one of the most important decision making problems including both qualitative and quantitative factors to identify suppliers with the highest potential for meeting a firm’s needs consistently and at an acceptable cost. In this paper supplier problem in Pars Neopan Company was studied and fuzzy AHP methodology was used for this work. For designing hierarchical structure, after definition of criteria and index, pair-wise comparison questionnaire is designed and distributed among the company experts. After gathering questionnaires, weight of criteria, index and alternatives are calculated and supplier with highest weight is selected as the best supplier. Results show that supplier criteria is most important criteria for supplier selection and product price, capacity and product quality are most important index in supplier selection respectively.

Knowing useful life of equipment is important for support sections, especially in military organizations. Because early replacement has extra cost and delay in replacement reduce mission efficiency and increase repairmen costs. Thus calculating operational life of equipment can be used to facilitate the management of equipment. The main purpose of this study is providing a model for determining the standard life, operational life, remaining life, equipment replacement time of capital equipment in the organization. This model is considered a useful tool for managing the equipment.It was designed a comprehensive model. This model has three main parts that in each section offered suitable method based on organization conditions. In the first part, standard life calculated based on existing standards, manufacturer advice and expertise. In the second part, environmental conditions, affecting factors on life and their impact is determined with the Delphi method. In the third section, the remaining life of equipment calculated based on previous and future usage of equipment and coefficients were calculated in the second section. The model was implemented in the organization and its results show the model accuracy is above 80 percent.

Forecasting is one of the most important and complicated steps of logistical patronage in organizations, especially in military and disciplinary ones. The vital role of this process in optimum accomplishment of logistical functions has increasingly proposed the necessity of forecasting system development. So optimum use of organization’s sources, in addition using the developed potentials in this field, has brought serious attention to correct forecasting and estimation and suitable use of it’s results in decision making and planning processes. Regarding the importance of the subject, development of forecasting system would be the best indicator in practical methods in this field to reduce damages and inaccuracy costs in logistical activities. This paper has attempted to show the importance of forecasting and estimation in logistical functions and to discuss and survey the practical methods to launch this system. This paper is obtained through study in library and internet surfing. It was found in these surveys that for system pitching and improvement in forecasting and estimation accuracy, total logistical informative systems should be integrated and act as a solid standard system

The purpose of this study is determination of current systems of produce and distribute of hand-woven carpet based of push and pull theories in Kurdistan province. For achievement to this purpose 100 people whom active in this industry was selected as sample. The current study base of objective is a played research and based of data collecting is descriptive research.The results of this study indicated that in Kurdistan province both of produce and distributive systems of hand-woven carpet is based of push system. In the other word in produce of hand-woven carpet has not been attention to customer style in selection of raw material, kind of spin in raw material, kind of dyeing, kind of design, size of hand-woven carpet row-count and kind of applied. Also in distribute system don’t attention to issue such as size of certify, prepare of service after sales, private delivery, take care of wet, shredding and decay of hand-woven carpet. Also based idea of people who they active in this industry with emphasize of customer style in produce and distribute, there are possible change the current supply of hand-woven carpet.

In this research we approach to select most appropriate suppliers utilizing qualitative and quantitative factors and order them lot size of product to supply and distribute them in several period of time. to meet the objective of this research, a supplier selection multi-criteria decision making model is developed using QFD, AHP and mathematical programming methods. this proposed model consist of two phases: qualitative and quantitative. in qualitative phase, the potential suppliers are evaluated by means of qualitative criterion and the result is the numerical weight of each supplier. These normalized weights are deployed in purchase value function in quantitative phase. The ultimate goal of this research is not reducing the cost alone, but to reduce the cost to the level that customer satisfaction is provided.

By passing the traditional economy and importance of competition in new dimensions, customer is the main part of all activities in organization. From the competitive point of view, surviving of all organizations is depended to identifying and attracting new customers and keeping the current customers. Since the distribution companies are somehow service organizations and their main activities are also related directly to retailers, therefore Satisfaction and loyalty of customers are terms which are very important for these companies. Thus the purpose of this research is identifying the affecting factors on loyalty of distribution companies, and then evaluating these factors in the PAKNAM distribution company by using various models in the field of customer satisfaction and loyalty. At the end we will present a model for customer loyalty for this company. The results of this research show “The ways of making good and friendly relationships with customers” has the high effect on loyalty. In addition “incentive methods” and “The process of recording order for goods” are two factors which have effect on customer loyalty from one side and on the other side “increasing the satisfaction” has indirect effect on “increasing the loyalty”. Also some factors such as “The ways of making friendly relationships with customers” and “competitors actions” are just effective on customer loyalty and there is no relationship with customer satisfaction. On the other hand two components of “pricing portfolio of goods” and “the delivery process” are indirectly effective on creating customer satisfaction and lead loyalty but they don’t have direct with loyalty.
