The Analytic Hierarchical Process (AHP) determines the relativeimportance of a set of alternatives in a multi-criteria decision problem.AHP has a hierarchial structure and based on pairwise comparisons ofthe project alternatives as well as pairwise comparisons of the multicriteria. Two separate algorithms have been presented for measuringthe inconsistency ratioes of pairwise comparisons matrix andhierarchical structure. In this paper these algorithms and one of theapproximation methods, have been extended for measuring theinconsistency ratioes and alternatives’ weights in fuzzy AHP. Anumerical example is used to illustrate these methods.

Traveling salesman problem (TSP) is one of the most well-known combinational optimization problems which recently has been a suitable base to validate different heuristic and Meta heuristic algorithms. Multiple application of this problem in both theoretical and operational field is remarkable to researches. Mate heuristic Optimization algorithm by ant colony is a kind of successful methods which has been used to solve discrete combinational optimization problems recent years. An algorithm based on ant colony optimization is presented in this paper to solve fuzzy traveling salesman problem. Presented algorithm has been programmed and run at C++ environment and results of each run were compared with coded results of Branch and Bound algorithm by Lingo 8.0. Suggested algorithm has resulted successfully in small scale and in the case of large scale has resulted to feasible solution at short time.

In optimizing an investment portfolio, the aim is to determine optimal value of per security, where prepares the minimum risk and the maximum return. One of the methods to measure risk of portfolio is Value at Risk (VaR). In the VaR method, risk of securities portfolio is estimated for a time horizon in future. In recent years, volatilities of exchange rate have been led to bankruptcy of many important industries of Iran. Hence in this paper, the investment risk in an exchange portfolio concluding five main exchange in the trades market of Iran is measured by using the VaR method and will be determined the weight optimal value of per security in exchange portfolio through to minimize the risk of investment portfolio.

The methodology of six-sigma is one of process improvement’s approaches that its aim is efficiency improvement of process, stability, customers’ satisfaction and cutting deviations such as wastage, reworking and costs. Heretofore different techniques have been introduced for achieving to this aims, so that one of their most efficient is Design of Experiments (DOE). The DOE technique is a scientific method for introducing the main parameters related to a process, where specifies the optimal application of this parameters for increasing the performance and the capacity of process. In this paper, application of the DOE is illustrated in the six-sigma methodology to decrease process time of outsourcing contracts adopting of industrial services engineering of Iran khodro corporation (ISEIKCO) and will be determined the principle parameters which affect on time of this process. Also, statistical analysis will be used for specifying the counteract affect of effective parameters and are proposed an improvement approaches to decrease processing time, where finally the obtained results will confirm the time efficiency improvement of outsourcing process.

The researches show that the implementation of Just-In-Time isn't unique in all situations. The implementation of this system may be differed in different companies, regions or countries and the some components that are needed to situations may be isn't vital in other situations. The purpose of this study is to identify elements and components that are critical to lust-In-Time success. This articles goal is proposing a method for this notification in lust-In-Time implementation by using antropy, TOPSIS and Pareto techniques. In this method we use TOPSIS and Pareto techniques for setting a priority and then selection of component and use entropy method for giving coefficient to TOPSIS matrix. At the end, in this case 5 components from 11 possible components in this system to implement in these companies have extracted.

The purpose of this article is about soft computing and its different methods for modeling phenomena. Soft Computing refers to the evolving collection of methodologies used to build intelligent systems exhibiting human-like reasoning and capable of tackling uncertainty.
In this paper, we describe the neural networks approach in soft computing at first. Then, other approaches such as genetic algorithm and machine learning will be described. Since the main goal of building the model is knowledge extraction, finally, we will describe the various methods of knowledge and rule extraction from neural networks.

In recent years 360 degree feedback have been in a growing number of leading firms and it has become a tool for assessing manager competencies and providing feedback them about how they are viewed by direct subordinates peers and in order to changing their behaviors. Its popularity is of problems of traditional assessment systems and advantages of 360 degree feedback. Indeed the 360 degree feedback is designed to enable all the stakeholders in a person’s performance to comment and give feedback: their boss or indirect reports peers and internal or external customers and so on. This empirical research data was collected through specific questionnaire eight competencies including communicating planning organizing controlling leadership decision making & teamwork from four self, boss, direct subordinates and customers. Analyzing data by ANOVA technique shows that there are a significant difference self, boss subordinates and customers perception in managers’ competency assessment. Then assessment results of each source have been grouped by LSD technique: firs group is self-assessment is subordinates and customers assessment and finally third group is assessment.

Customer relationship management and business to business model are two major factors in success of modern trade. It is that for development of electronic business in Iran entering to purpose. CRM is a point of view that emphasizes on the cooperation order to create value. This view point which is the result of recent improvement of information technology wants to improve the relationship between the stakeholders to satisfy the requirements of the customer collecting data. Therefore it is important to satisfy the available customer and have a long range relationship with them.
Electronic business helps management to keep to relationship customers in the new century which new methods are available distribution in the extended geography and support the distribution marketing. Although these two have different sections but they have sections. Integration of these two elements have very benefits on sale service to the customers and informational support of business process.

Modern and new technologies have changed the management view and the methods of problem solving and management of organizations. For effectively managing the organizations at todays changing environment managers should view different global economic, social, political and legal conditions and must pay attention to factors such as developing deformation and communication technologies and changing customers expectations. For with respect to each condition and factor they needs appropriate information to increase their knowledge and decrease their uncertainty to have effective performance. In this way it seems necessary to consider information technologies and total quality management and understand their impact on efficiency and effectiveness.
In this article through citing the relationships between information technology and total quality management we attempt to examine their impact on organizations efficiency and effectiveness. Therefore we study the concepts of effectiveness efficiency and productivity and then point to the relationships between information technology and total quality management and to the impact of these relationships on organizations efficiency and effectiveness. Because, today managers' attitudes and views to quality in firms is new. Production with desired quality requires not only clear definition of goals, specific policies and procedures for each part of work and each stage of process but also real time inspection, measurement and documentation systems.
