There is a growing need for the integration of environmental management into Human Resource Management (HRM) practices; such effort is known as Green HRM initiatives. The aim of this study is to identify barriers of green human resource management in Iran & apos; s oil industry. For this purpose, mixed method has been used. In the article, existing literature was examined and questions were designed and 12 experts of international oil industry were interviewed. The aim of these interviews was to design questionnaire and collects the necessary information. To examine the reliability of the questionnaires, Cronbach alpha coefficient was equal to 0.732, which validated the reliability of the questionnaire. Finally, the questionnaires were shared among 31 members of oil & apos; s experts and HR managers. The results of the study have shown that the lack of comprehensive plan to implement green HRM and ambiguous of green values were in the highest level and they were considered as the most important barriers. Furthermore, staff resistance had the lowest importance.

Optimization of a multi-response dynamic system aims at finding out a setting combination of input controllable factors that would result in optimum values for all response variables at all signal levels. In real life situation, often the multiple responses are found to be correlated. The main advantage of PCA-based approaches is that it takes into account the correlation among the multiple responses. Two PCA-based approaches that are commonly used for optimization of multiple responses in dynamic system are PCA-based technique for order preference by similarity to ideal solution (TOPSIS) and PCA-based multiple criteria evaluation of the grey relational model (MCE-GRM). This paper presents a new PCA-based approach, called PCA-based utility theory (UT) approach, for optimization of multiple dynamic responses and compares its optimization performance with other existing PCA-based approaches. The results show that the proposed PCA-based UT method is superior to the other PCA-based approaches.

Enterprise architecture, with detailed descriptions of the functions of information technology in the organization, tries to reduce the complexity of technology applications resulting in tools with greater efficiency in achieving the objectives of the organization. Enterprise architecture consists of a set of models describing this technology in different components performance as well as various aspects of the applications in any organization. Therefore, information technology development and maintenance management can perform well within organizations. This study aims to suggest a method to identify different types of services in service-oriented architecture analysis step that applies some previous approaches in an integrated form and, based on the principles of software engineering, to provide a simpler and more transparent approach through the expression of analysis details. Advantages and disadvantages of proposals should be evaluated before the implementation and costs allocation. Evaluation methods can better identify strengths and weaknesses of the current situation apart from selecting appropriate model out of several suggestions, and clarify this technology development solution for organizations in the future. We will be able to simulate data and processes flow within the organization by converting the output of the model to colored Petri nets and evaluate and test it by examining various inputs to enterprise architecture before implemented in terms of reliability and response time. A model of application has been studied for the proposed model and the results can describe and design architecture for data.

This research aims to offer a fuzzy approach for calculating Tehran & apos; s air pollution index. The method is based on fuzzy analysis model, and uses the information about air quality index (AQI), included on the website of Tehran’s Air Quality Monitoring And Supervision Bureau. The contrived fuzzy logic is considered a powerful tool for demonstrating the information associated with uncertainty. In the end, several graphs visualize this inferential system in various levels of pollution.

This paper deals with the problem of grouping a set of objects into clusters. The objective is to minimize the sum of squared distances between objects and centroids. This problem is important because of its applications in different areas. In prior literature on this problem, attributes of objects have often been assumed to be crisp numbers. However, since in many realistic situations object attributes may be vague and should better be represented by fuzzy numbers, we are interested in the generalization of the minimum sum-of-squares clustering problem with the attributes being fuzzy numbers. Specifically, we consider the case where an object attribute is a triangular fuzzy number. The problem is first formulated as a fuzzy nonlinear binary integer programming problem based on a newly proposed dissimilarity measure, and then solved by developing and demonstrating a problem-specific ant colony optimization algorithm. The proposed algorithm is evaluated by computational experiments.

This paper presents an empirical investigation to study the effects of different factors for regional market entrance. The population of this survey includes all producers who are involved in export of industrial goods in city of Tehran, Iran. The study designs a questionnaire in Likert scale and distributes it among some randomly selected experts who were involved in production and export of different products. Cronbach alpha was calculated as 0.856, which is well above the minimum acceptable level. Using principal component analysis, the study has detected seven factors including product development, government support, strategic orientation, customer satisfaction, competitive pressure, organizational capabilities and distribution strategies influencing on product development. In addition, the implementation of structural equation modeling has determined that product development, government support, strategic orientation and competitive pressure maintained the highest effects on product development.

In many quality control applications, the quality of a process or product is explained by the relationship between response variable and one or more explanatory variables, called a profile. In this paper, a new fuzzy EWMA control chart for phase II fuzzy profile monitoring is proposed. To this end, we extend EWMA control charts to its equivalent Fuzzy type and then implement fuzzy ranking methods to determine whether the process fuzzy profile is under or out of control. The proposed method is capable of identifying small changes in process under condition of process profile explaining parameters vagueness, roughness and uncertainty. Determining the source of changes, this method provides us with the possibility of recognizing the causes of process transition from stable mode, removing these causes and restoring the process stable mode.

Medical tourism is an international phenomenon where some tourists travel long to reach treatment-therapeutic services because of high expenses, long waits, lacking in insurance, and applying services and insufficient access to health services in the destination. This industry, now, by making 60 billion dollars annually in international level, has been considered as one the most profitable markets and the number of countries to provide facilities and treatment services for foreign tourists tend to increase. Many countries provide applicable and legal plans for development of this industry. This paper aims at planning and improving medical tourism in megalopolis Shiraz. The dominating approach in the present study is developmental-applied and the method is descriptive, analytical and survey study. To analyze the data and to test the research hypothesis, the linear Pearson correlation and ANOVA were used. The results of the present study have indicated that all quality factors of treatment and tourism services, culture, facilities, medical and tourist equipment and ICT, had positive and direct correlation with developing medical tourism and the factor of price had negative and reverse correlation with it. In other words, the higher the price is, the less the medical tourism development is and vice versa. Also, the ANOVA showed that among medical tourists from various countries regarding satisfaction with the price of treatment and tourist services, the quality of treatment and tourist services, culture, facilities, medical and tourist equipment and ICT, there are significant differences and Kuwaiti tourists were the most satisfied tourists and Afghani ones were the least satisfied.

In this paper, we explored an economic production quantity model (EPQ) model for finite production rate and deteriorating items with time-dependent trapezoidal demand. The objective of the model under study is to determine the optimal production run-time as well as the number of production cycle in order to maximize the profit. Numerical example is also given to illustrate the model and sensitivity analyses regarding various parameters are performed to study their effects on the optimal policy.
