In today’s business world, human resource is concerned as fundamental capital of organizations. In fact, human resource is the chief organizational tool to achieve the strategies and goals. According to the significance of human resource, the present research aimed to develop a framework, by which the human resource strategies can be developed on the basis of the knowledge dimension, which is one of the most important resources for generating competitive advantage. Previous models and approaches did not concern to the knowledge aspect of the employees in human resource strategy process, which is a significant lack in these models. The main difference of the framework of this research and that of previous study is paying due attention in work to the knowledge in human resource strategy development process as a determinant factor, especially for the knowledge based organizations. Indeed, the main finding of this study is development of a human resource strategy framework that emphasizes to the knowledge aspect, which is applicable in new businesses of the present era of transferring to the knowledge based organizations. For validating the suggested framework, the expert opinion, one of the research methods for conceptual studies, was used.

Selecting appropriate suppliers can significantly reduce costs and increase the competitiveness of organizations. On the other hand, in today’s competitive environments, high speed of changes increases uncertainty and ambiguity in decision making. Considering these two important issues, in this research, fuzzy-robust approach was is used to increase certainty and remove ambiguity in planning of the supply parts for two products of Iran Khodro Company (Tehran, Iran). Due to high number of parts were in any product, only the important parts were selected for this survey. Model of supply of these parts (was designed) in the form of a multi-objective linear programming model. Because of the uncertainty of some parameters of the model, these parameters are considered as random variables but there is no exact value for them. In order to remove concern and ambiguity about these parameters regarding the length (half-length) of their intervals, with help new approach (fuzzy-robust), the model was converted into fuzzy-robust model to achieve dependable solutions. Finally, the quality of solutions was analyzed by simulation technique.

This paper seeks to investigate the initial aftermarket performance of 142 Iranian IPOs listed on Tehran Stock Exchange for the period 1997-2005 to contribute to the growing body of international evidence on the anomalous performance of IPOs in the short run. The results suggest that Iranian IPOs are underpriced on the initial trading window of 1 through 4-weeks on average of 14.85%, as are almost all IPOs in different countries. In terms of industry sub-sectors, the adjusted initial underpricing is 70.24% for minerals, 62.31% for oil and nuclear fuel, and 1.12% for multimedia industries. Finally, the investigation of possible factors influencing the high initial positive returns in TSE (the size of the issue, age of the issuing firm, financial risk of the issuing firm, gross proceeds from the issue, market sentiment, offer rate and the institutional ownership of the issue) indicates that the offer rate and financial risk of the issuing firm are significant determinants of the initial underpricing of Iranian IPOs. As such, the results yield strong support for the signaling hypothesis as possible explanation for the underpricing phenomenon on the Iranian IPO market.

Calculation of Derivations from every objective of the project is very important for both contractors and employers. Time overrun is the function of all project risks. A tool that can assess the risk levels and estimate the derivations from the planed duration is very useful for contractors. This research tries to propose a new methodology to determine the schedule risk of construction projects and the total time overrun. This methodology uses influence diagram to construct the risk model and fuzzy risk assessment system to estimate time overrun for every activity. Then the information of fuzzy risk assessment model is used by scheduling the softwares such as MSP or Primavera to calculate the time overrun of the project. This model has been used in one of the track renewal projects of Iran Railway Administration.
The model was validated by using the estimated data produced by model and the real data of the activities’ duration. Then the mean absolute percentage error (MAPE) was calculated for the activities and the project. MAPE of the activities was equal to 10.75% and the estimated duration of project was equal to 105.24 time unit. In comparison with the real duration of project (which was equal to 113 time units and MAPE for the whole project was equal to 6.7%), it can be concluded that fuzzy risk assessment model has remarkable accuracy to be used in construction projects.

The need for designing and implementing performance assessment systems at R&D centers is one of the urgent issues of all industries. Assessment of R&D projects has become one of the most challenging decision making issues for the managers of R&D centers. Multi-criteria decision making methods have so far been used for the assessment of R&D projects in different stages of their lifecycle. Our approach is to develop Data Envelopment Analysis by combining Balanced Scorecard and Data Envelopment Analysis. Inputs and outputs for the integrated DEA-BSC model have been extracted from “Balanced Scorecard for R&D projects”. The major goals of the integrated DEA-BSC approach are as follows: increasing the reliability of inputs and outputs criteria, improving the calculated efficiency of all sections and striking a balance between the efficiency and the effectiveness of different sections. This model has been implemented in an industrial research laboratory for R&D projects as a case study. The results showed that synergizing between BSC and DEA in R&D projects causes the: achieving of the expected objectives of each project and balancing and optimizing the usage of resources to meet the desired outputs.

In spite of the growing attention to employee empowerment, there exists little understanding of how the process of employee empowerment occurs?, what are the psychological processes underlying employee empowerment? and What important organizational variables reliably predict employee empowerment? Although many authors have emphasized the critical role of leadership in the empowerment process, there are few scientific studies that have examined the effects of leadership behaviors on employee empowerment. Using the existing literature and theories, the focus of the current study is to answer the following question: How do transformational leaders empower employees? Using data collected, results of analyses suggest that transformational leadership has much impact on employee empowerment. Follow- up analyses indicated that there is significance relation between transformational leadership and meaning, choice, competence, and impact.

In this article, we examined the policy makers’ attitude by the budget statistical data of the education section and it's sub-plans during 1353-through 1388 to find the evidence of punctuated equilibrium and incremental modals.
For this propose, we used Kolomogrov, Kurtosis and Skewness tests for analyzing the fifteen plans of the education section in the annual countrywide budget.
The results suggest that the model of core plans in education section is punctuated, but the sub-and specialized plans can be defined as incremental model. It seem that in addition to oil plans, cultural preferences and policy makers beliefs, the relation of type of plan with the main mission is effective in the fluctuations in the education section’s annual budgeting process.

Financial Service Providers (FSPs) like other organizations can use Customer Lifetime Value (CLV) as an instrument to achieve their targets in Customer Relationship Management (CRM). Although various studies have been done about this concept, CLV case studies are scarce in banking industry. In this research, in order to present a model to determine CLV in banking industry, customers with current account in a bank in Iran were studied. Determining the relative importance of R, F and M variables that are used to cluster customers, ranking the clusters of customers according to their CLV and understanding the best strategies for bank to treat with each cluster are among the other goals of this study. Three main variables were used to apply the model; a) Recency: the length of time since the last transaction (in days), b) Frequency: number of positive transactions and c) Monetary: balance of account (in Rials). Also wR , wF and wM were used as the relative importance of R,F and M variables. We used the ideas of experts and marketing managers and the data of transactions from the random samples of 382 corporate customers and 5113 individual customers, who had current account in 33 branches of a bank in Tehran. The analytical Hierarchy Process (AHP) was applied to determine wR , wF and wM in evaluating CLV. Then WRFM model was used to cluster the customers and rank them based on their CLV for two groups of corporate and individual clients Clustering and Discriminant Analysis techniques were implemented for this section. Finally, the best strategies for bank to treat with each cluster of the customers was determined.
