Organizations are considered to be Pillars of the community. Senior Management performance is the result of proper and timely mix of human resources. The concept of culture is an important factor that determines management practices. IT influences on management performance. Therefore Human Resource Management (HRM) procedureslead to higher firm performance and act as a source of long-lasting competitive advantage. This study attempted to test the relationship between organizational culture values and effectiveness of HRM procedures. The study population consisted of all employees of “Yazd Pich Chehre” (60 cases), which 38 sample were selected as a random sample. Data were collected using questionnaires ant its validity and reliability tested through factor analysis and Cronbach's alpha respectively and both has been approved. Spearman correlation coefficients applied for analyzing data. Results show that there is a significant and positive correlation between organizational culture values and HRM procedureseffectiveness.

A Production system with push control system uses materials requirements planning (MRP) to plan purchasing and manufacturing physical resources. Therefore a material planning system provides a basis for scheduling production and purchasing materials. Firms are looking for a way to deal with fluctuations causes by environmental uncertainty, which include fluctuations in demand and supply of raw materials. Using safety stock which is a certain amount of goods or materials kept as inventory to deal with uncertainty is one way to deal with fluctuation issue. Despite the safety stock importance, there is no comprehensive framework for decision making about this issue. The aim of this paper is to provide a dynamic model for MRP system. By applying this model, a suitable policy of safety stock is achieved. Then, the appropriate amount of safety stock can be obtained and total inventory cost can be reduced. A system dynamics approach is used to simulate the model and demand and lead time are considered probabilistic. After designing the model, different scenarios of safety stock have been proposed. Used criteria for selecting an appropriate scenario is total inventory cost, and finally a scenario in which the total inventory cost is at its lowest amount would be chosen as the best scenario.

Performance evaluation is prerequisite for many domains of human resource, which precise implementation of which will result in efficiency and effectiveness of performance feedbacking, training and development, promotion of employees, human resource planning, etc. Accurate weighting of evaluation indicators alongside with considering synergy and interaction force of indicators can affect evaluation results. Also differences of different levels of an indicator importance should be considered according to its great significance. This paper tries to realistically weight indicators using Taguchi experimental design method and considering two aforementioned points. An eight-stage model is presented and performance evaluation indicators for a bank cash register are specified. A questionnaire is designed based on proposed Taguchi orthogonal tables. Experts in banking sector are asked to answer the questions of each dimension to determine the weight of indicators. Results of implementing proposed model as ANOVA table show that Taguchi experimental design method can be a proper method in weighting indicators and taking into account the amount of error factor and decisions can be made according to stability of obtained results.

In today's dynamic environment, having a proper strategy is not enough for companies to be able to adjust themselves with their environments. Companies through choosing a suitable organizational structure can benefit innovation to achieve sustainable competitive advantage. The aim of this study is testing the mediating role of organizational structure (formalization, centralization, complexity) between environmental uncertainty and organizational innovation. The questionnaire was used to collect data with high reliability and Structural Equation Modeling and Partial least squares were used for analyzing data. Data collected from medium and large manufacturing firms in the Mashhad city. The results showed that the theoretical model was good fitted and the relationship between environmental uncertainty and dimensions of Organizational structure (complexity, formalization and centralization) is meaningful. Also the relationship between complexity and formalization with organizational innovation were significant. Organizational formalization and complexity mediated between environmental uncertainty and organizational innovation was meaningful but mediating role of centralization was not meaningful.

Leadership is one of the most important concepts in management literature. Organizations cannot achieve their predetermined goals without an efficient leadership. This study tries to identify the most effective factors on leadership intention and demonstrate them as a conceptual model. Leadership intention means persons’ scheduling for self-individuals future and whether he or she is willing to be responsible for leaderships roles. The conceptual model of this study is created according to subject literature. Questionnaires distributed among management students of Tehran universities using convenience sampling and 845 were collected. Data analyzed using structural equation modeling. The results showed that fame-seeking, social networks, leadership motivation and person’s leadership efficiency have positive and significant Influence on his/her leadership intent. Dream, risk taking, independence, confidence, curiosity and emotional intelligence were among other variables that their effects on leadership intent was not confirmed.

Present a model for analyzing agents’ behaviors and determining their efficiency factor, while responding to calls in call centers is the main goal of this study. The aim of this model is to identify the strengths and weaknesses of the agents providing these services to customers. The proposed process defines three criteria namely F, U and Q which represent the number of responding, duration of responding to a unit call and the quality of responding to calls. After obtaining experts’ opinions, parameters were weighted. Then, based on the number of optimum clusters provided by Davis we tried to cluster the factors using K-Means. In the next stage criterion to measure the efficiency of agents were defined, and results were analyzed. The use case carried out on 3401535 records of 158 answering agents in the call center for one of the companies affiliated to automobile industry. The results show that efficiency of agents is not relation to gender. The company does not use enough “best agents” for answering customer calls; whereas one of the highlights of Human Resource Management is the efficient use of an expert. On the other hand the results show that company should pay attention to the education and skills of hired agents who answer customer calls.

This study is aimed to design and examine a model for situational antecedents of IS/IT user satisfaction in Galougah and bandargaz’s administrative organizations. In this regard, questionnaires related to research variables were prepared and after ensuring the reliability and the content validity, were distributed among 379 employees as a sample. In order to test the hypotheses, first of all, measurement models were estimated and tested. Then, the data were fitted to structural equation. Results showed that all of situational factors, except IT Infrastructure of IS/IT, had positive meaningful effects on perceived ease of use in %99 confidence level. Moreover, perceived ease of use had a significant positive effect on user satisfaction. Among the situational factors examined, only task-technology fitted and technical support had a significant positive effect on perceived usefulness of information technology; however the significant effect of perceived usefulness on user satisfaction was not confirmed. Finally it was revealed that among mentioned situational factors, it is user involvement that has a direct positive effect on user satisfaction. Also, based on the result of the side-study, perceived usefulness of IT/IS has a moderating effect on the impact of IS/IT ease of use on user satisfaction.
