The research method of the present study is a combination (qualitative-quantitative) with an exploratory approach. In the quantitative part of the statistical society, there were 655 cooperative companies with 19,901 thousand cooperative members in Zahedan city, out of which 8 cooperative companies with 300 members were randomly selected as a sample. Then, based on Morgan's table, 169 questionnaires were completed randomly and with proportional assignment in all eight companies. In order to analyze the data in the qualitative part, the meta-combination method was used through the seven-step method of Sandelowski and Barroso. Based on this, 47 articles in the field of cooperatives were analyzed and research indicators were identified. In the second stage of the research, in order to validate the research model, structural equation modeling technique was used with Smart PLS software version 2, and AHP method was used with Expert Choice software version 11 to prioritize the identified indicators. In this research, the data collection tool is a researcher-made questionnaire. The validity of the questionnaire was confirmed through exploratory factor analysis. The reliability of the questionnaires was calculated using Cronbach's alpha test of 0.91, which indicates the appropriate reliability of the research tool. The results of the research data analysis indicated that the marketing index with a weight of 0.88 has the highest priority in the empowerment of cooperatives,

Despite the fact that student cooperatives are setup with the aim of promoting entrepreneurial competencies among students; however, due to not following the indigenous model, they have not been able to take appropriate action to promote entrepreneurial and business activities among students. In this way, the purpose of this study was to design a model for the extension of entrepreneurial activities in student’s cooperatives, for which the qualitative paradigm and grounded theory was used. The study participators consisted of all members of agricultural student cooperatives in the universities (Razi, Kurdistan, Bouali, Lorestan and Ilam universities) of the west of Iran. The studied samples were first selected purposefully and then theoretically. Theoretical saturation was obtained after 25 in-depth one-on-one interviews. In order to analyze the data, open, axial and selective coding was used. Findings showed that environmental support, social capital, psychological characteristics, human capital, economic motivations and role models as causal factors; Administrative bureaucracy, financial barriers, cultural barriers, structural barriers and environmental opportunities as underlying factors; and climate change, market fluctuations and environmental turbulence were identified as intervention factors that affect the extension of entrepreneurial activities in agricultural student cooperatives in the west of Iran. Strategies for promoting entrepreneurial activities in student cooperatives in the west of Iran included educational-extension, modeling, reducing administrative bureaucracy, support-motivation and financial facilities strategies, which ultimately resulted in entrepreneurial activities extension among agricultural students such as developing entrepreneurial competencies, development Social, agricultural development and economic development.

The aim of this study was to investigate the impact of environmental values, attitudes and ethics with environmental behaviors among ranchers’ members of rangeland cooperatives in Gonbad Kavous. The statistical population was 644 operators who were members of rangeland cooperatives in 17 conventional systems, of which 240 were selected by stratified random sampling using Krejcie and Morgan table. A questionnaire was used to collect information. The content and appearance validity of the questionnaire were confirmed by experts, and its reliability was confirmed using Cronbach's alpha method. Data were analyzed using mean comparison, correlation and regression tests. The results of the mean comparison test showed that there is a significant difference between different groups of respondents according to the level of education regarding the component of environmental ethics, based on the history of animal husbandry, regarding the component of environmental value, based on the second job, regarding the components of attitude, ethics and environmental behavior, and based on the frequency of participation in training courses on value components and environmental behavior. The results of correlation test showed that there is a positive and significant relationship between the variables of attitude, and environmental ethics, and the environmental behavior of the respondents. The results of regression analysis showed that having ethics and environmental attitude has a positive effect on environmental behavior, and ethics has a greater effect. This study recommended increasing the use of cooperative capacity of ranchers by creating and supporting environmental organizations of ranchers to protect the environment.

Cooperative governance mechanisms play an important role in the organization's strategic decisions. Post-crisis studies of any cooperative have shown that the board's inadequacy is one of the most important causes of the crisis, as the board can affect the quality of risk management and risk disclosure. This study examines the impact of cooperative governance mechanisms on cooperative risk-taking. This study is a survey and library research and is an applied, descriptive and correlational research that has been done by selecting information of agricultural production cooperatives in Guilan province. The model used in this study consisted of panel regression model and the tests used were Lemar test, Fisher test and t test. Eviews software was used to fit the model. Co-operative governance mechanisms include board size, board independence, and CEO duality, and risk indices include three indicators, including special risk, survival risk, and activity risk. The results showed that the specific risk was significantly correlated with the coefficients of board size, managerial dichotomy, and board independence. Survival risk was significantly correlated with board duality variables and board independence. There is a significant relationship between activity risk and board duality and board independence.

Cooperation is undoubtedly a great tool to deploy Chilean foreign policy, since it creates long-term ties with the beneficiary countries. This generates small-scale retributions in bilateral relations and in specific technical areas, as well at the multilateral level. Chile's cooperation flows have undergone important changes since the creation of the International Cooperation Agency in the 90s, to the present, since Chile has gone from being a net recipient, to being a participant in international cooperation through the South-South modality or horizontal. In spite of this, it is not possible to clearly establish the benefits that cooperation generates for the country because there is no clear evaluation methodology. Finally, Chilean cooperation does not have a priority budget, and its programs are affected by short-term issues in the absence of a more leading role in the formulation of Chilean foreign policy.

The grey uncertainty is a new methodology focusing on the study of problems involving small samples and poor information. It deals with uncertain systems with partially known information through generating, excavating, and extracting useful information from what is available. This paper focuses some division solutions for cooperative games, called the equal surplus sharing solutions. A situation, in which a finite set of players can obtain certain grey payoffs by cooperation can be described by a cooperative grey game. In this paper, we consider some grey division rules, namely the equal surplus sharing grey solutions. Further, we focus on a class of equal surplus sharing grey solutions consisting of all convex combinations of these solutions. An application from Operations Research (OR) situations is also given.

In this paper, we develop an integrated bi-objective model of two-stage supply chain composed of a vendor and a buyer under an imperfect production process. The stochastic inflationary condition wherein the first objective is minimizing the expected costs of the proposed supply chain model and the second objective is minimizing buyer’s shortage variance. We assume lead time and ordering cost are controllable parameters and lead time crashing cost is considered as a function of both order quantity and reduced lead time. An effective solution procedure is developed to determine the optimal policy of the proposed model. Finally, a numerical example and sensitivity analysis are proposed to show the performance of the model.

Natural disasters, accidents, and crises, that cause widespread destruction and inflict heavy casualties, accentuate the importance of a careful planning to deal with the aftermath and mitigate their impacts responsively. Thus, the logistics of disaster relief is one of the main activities in disaster management. In this paper, the response phase of the disaster management cycle is considered and a multi-objective model for location and routing of vehicles is presented. Uncertainties in transfer time, demands of regional warehouses in the damaged areas and inventories at supply centers in different periods are taken into account. Three objectives are considered in this model. Two objectives consist of minimizing total time required to reach the damaged areas and maximizing satisfaction of the damaged areas. The third objective, which is of secondary importance, attempts to minimize total costs, including startup costs, transfer costs, and shortage costs. In order to convert the proposed multi-objective formulation to a single objective one, Global Criterion approach is applied. Afterwards, the obtained single objective model is solved using an efficient genetic algorithm and simulated annealing. Finally, a case study in Southern Khorasan is conducted and the applicability of the proposed model is examined.

Recently, Kharazmi and Saadatinik (2016) introduced a new family of lifetime distributions called hyperbolic cosine – F (HCF) distribution. In the present paper, it is focused on a special case of HCF family with exponentiated exponential distribution as a baseline distribution (HCEE). Various properties of the proposed distribution including explicit expressions for the moments, quantiles, mode, moment generating function, failure rate function, mean residual lifetime, order statistics and expression of the entropy are derived. Estimating parameters of HCEE distribution are obtained by eight estimation methods: maximum likelihood, Bayesian, maximum product of spacings, parametric bootstrap, non-parametric bootstrap, percentile, least-squares and weighted least-squares. A simulation study is conducted to examine the bias, mean square error of the maximum likelihood estimators. Finally, one real data set has been analyzed for illustrative purposes and it is observed that the proposed model fits better than Weibull, gamma and generalized exponential distributions.

Scheduling problem for the hybrid flow shop scheduling problem (HFSP) followed by an assembly stage considering aging effects additional preventive and maintenance activities is studied in this paper. In this production system, a number of products of different kinds are produced. Each product is assembled with a set of several parts. The first stage is a hybrid flow shop to produce parts. All machines can process all kinds of parts in this stage but each machine can process only one part at the same time. The second stage is a single assembly machine or a single assembly team of workers. The aim is to schedule the parts on the machines and assembly sequence and also determine when the preventive maintenance activities get done in order to minimize the completion time of all products (makespan). A mathematical modeling is presented and its validation is shown by solving an example in small scale. Since this problem has been proved strongly NP-hard, in order to solve the problem in medium and large scale, four heuristic algorithms is proposed based on the Johnson’s algorithm. The numerical experiments are used to run the mathematical model and evaluate the performance of the proposed algorithms.

The main purpose of this study was to assess the factors that influence the success of rural production cooperatives in the South of Kerman province using descriptive-correlational design with the participation of 120 members of two Rural Production Cooperatives (RPCs) in the region (one successful and one failed RPCs). Therefore, participants were interviewed with the aid of a questionnaire containing both open and closed-ended questions. Face validity was confirmed by experts, and the questionnaire was subjected to reliability testing by using data collection in the pilot study with Cronbach’s Alpha value of 0.50 to 0.97. Comparative analysis revealed that suitable environmental and socio-culture condition were the key determinants for the establishing stage. Findings also showed that the desirable economic, personal, structural, environmental, and socio-cultural situations were important in stabling stage. This is while; the village’s environment, social capital, trust and cooperative structure were key determinants in the durability stage. Discriminate analysis showed that trust and cooperative structure were the most important significant factors to discriminate cooperatives. So, based on these findings, it is suggested that  for empowering members in team working, some workshops and training courses need to be held. Also, it is essential to expand cooperative activities according to the needs of the members.

This paper investigates an EPQ model with the increasing demand and demand dependent production rate involving the trade credit financing policy, which is seldom reported in the literatures. The model considers the manufacturer was offered by the supplier a delayed payment time. It is assumed that the demand is a linear increasing function of the time and the production rate is proportional to the demand. That is, the production rate is also a linear function of time. This study attempts to offer a best policy for the replenishment cycle and the order quantity for the manufacturer to maximum its profit per cycle. First, the inventory model is developed under the above situation. Second, some useful theoretical results have been derived to characterize the optimal solutions for the inventory system. The Algorithm is proposed to obtain the optimal solutions of the manufacturer. Finally, the numerical examples are carried out to illustrate the theorems, and the sensitivity analysis of the optimal solutions with respect to the parameters of the inventory system is performed. Some important management insights are obtained based on the analysis.

In the field of health losses resulting from failure to establish the facilities in a suitable location and the required number, beyond the cost and quality of service will result in an increase in mortality and the spread of diseases. So the facility location models have special importance in this area. In this paper, a successively inclusive hierarchical model for location of health centers in term of the transfer of patients from a lower level to a higher level of health centers has been developed. Since determination the exact number of demand for health care in the future is difficult and in order to make the model close to the real conditions of demand uncertainty, a fuzzy programming model based on credibility theory is considered. To evaluate the proposed model, several numerical examples are solved in small size. In order to solve large scale problems, a meta-heuristic algorithm based on harmony search algorithm was developed in conjunction with the GAMS software which indicants the performance of the proposed algorithm.

The study addresses Performance Control Matrix (PCM) to determine service quality items of priority for improvement. Most businesses focus on customer satisfaction when undertaking surveys of satisfaction and dissatisfaction, while generally neglecting employee satisfaction. Therefore, this study develops an integrated model to improve service quality in Taiwanese finance industry employees. A questionnaire is designed to determine the priority of improvement objectives derived from certain questionnaire items that fall into the improvement zone of the PCM. Ten items are found to fall into the improvement zone of the PCM. The present results show that the finance industry employees surveyed in Taiwan were dissatisfied with their job security, salaries, annual bonus, and fair distribution of operational profits. The ten improvement items mostly belong to two dimensions - ‘Pay and Benefits’ and ‘Motivation’. The managers of the financial institutions should seek to improve these quality attributes by devoting more resources to these items, thus promoting employee satisfaction.
