In turbulent environments, the urgent need of the organization is developing and improving flexibility and responsiveness to them. Therefore, the agility, the ability to sense environmental changes and responsiveness to changes in time and learning experiences, is an important index for improving the competitive activities. Regarding high importance of agility and its different aspects, just a few researches are conducted concerning the formation of agility aspects in organization. Based on dynamic view in competitive environments, the tools for achieving agility in organization are dynamic capabilities, so in this study is tried to present and test the model of agility aspects formation based on the most important dynamic capability, IT competency, in order to optimize competitive activities in IT industry of Iran. The result of this study show that IT knowledge based competency, knowledge reach and richness, improve sense and learning aspects of agility and IT process based competency, process reach and richness, improve responsiveness aspect of agility. Also improving the agility aspects of the organization promote competitive activity.
Annual medics is more noteworthy than other annual legumes in this type of cropping system due to its specific self-regeneration resulting from the gradual softening of its hard seed coat. Seed coat hardening is the main reason for seed dormancy in leguminous plants. Hardseededness of more than 90% prevents seeds from germination at the cropping stage in cereal-legume rotation systems. In the conditions and system status that the purpose cultivation is necessary that the seed with pods can be used without such rotational system of annual medic and wheat or barley (ley- farming) or similar cases and in a condition that can or should be compulsorily placed in the soil seed with pods like the end of first year rotational system of annual medics - wheat or barley (ley- farming) should be that of wheat, seed with pods in the soil should be deferred

In this paper, a gas pressure regulating station is mentioned. In order to generate power, the throttling valve system has been replaced with turbo expanders. Also, heat exchangers are utilized after expansion process with the purpose of producing refrigeration. Furthermore, a computer code has been developed based on Matlab software and an exergy analysis of this system has been conducted. To have a better insight of this study, the effects of key parameters such as 1st turbine pressure ratio (R), 1st turbine inlet temperature (T2), 2nd turbine inlet temperature (T4), turbine isentropic efficiency, and heat exchanger efficiency on the total exergy destruction and total exergy efficiency have been performed. The exergy analysis revealed that the preheater is the most exergy destructor in comparison to other components. This is due to the high temperature difference between working fluid and combustion temperature. In addition, it was found that an increase in T2 causes a reduction in the total exergy efficiency of the system, while an increase in T4 has a converse effect. Variation of R shows that for a specific value the system exergy efficiency has a maximum amount. Also, an optimization using a genetic algorithm has been conducted to find the optimal solution of the system. Due to the optimization results, the mean exergetic efficiency of the system is 78%. The optimized decision variables are R≈2, T4 ≈ 2-5 ºC and T2=T1. After optimization procedure for the mentioned cases, because of inappropriate effects of preheater utilization, expressed above, the turbines pressure ratio are set to values which finally lead to preheater omitting by the genetic algorithm.
In many developing countries including Iran, the presence of women in the labor market has not been increased with regard to their level of education. Similarly, there are plenty of obstacles hindering women economic activities outside their houses. The main purpose of this study was to analyze some Legal-Governmental barriers of rural women entrepreneurship in Ilam province. The research was an applied study type and due to the lack of control variables, it was considered as a semi-empirical and a casual–relative kind of research. Population of the study consisted of all entrepreneur women located at various rural areas of Ilam. A proportional stratified random sampling method was applied. The sample size was chosen up to 310 numbers of the target group to be able to use Cochrane formula. The main tool of the research was questionnaire which was developed in three main sections. Analysis and data processing was done at two steps. The descriptive statistics (central and dispersion parameters) and analysis (Spearman correlation coefficient) were used. Results of this study showed that government intervention in pricing, obstacles in the political and economic relations with other countries, Lack of coordination between agencies and organizations involved in entrepreneurship, Lack of encouragement of Entrepreneurs by the government, Lack of appropriate programs of entrepreneurship by the government, paying direct and indirect of governmental subsidies to the producers and existence of some obstacles to the import and export of products were the main Legal- Governmental barriers affecting rural women's entrepreneurship. Correlation analysis between variables indicated that there is a significant relationship between Legal- Governmental variables with the rural women's entrepreneurship.
Evaluation and selection of distributors are important issues in Supply Chain Management (SCM) and play an important role in making new market development. This paper provides a new method to categorize and select distributors. After determining criteria according to the service quality dimensions as a novel innovation, the fuzzy Adaptive Resonance Theory (ART) algorithm is utilized to categorize distributors according to their similarity. Then, two Multi-Criteria Decision Making (MCDM) techniques (i.e., AHP and FTOPSIS) are utilized to arrange distributors in their relative category. Finally, a numerical example is illustrated to examine the validity of the proposed algorithm. Results show that integrating MCDM techniques and neural networks can remove their deficiencies and provide comprehensive approach for partner selection in supply chain.
