Since the supply chain of the closed loop is not only a forward flow but also a reverse one; therefore, companies creating integrity between direct and reverse supply chain are successful. The purpose of this study is to develop a new mathematical model for closed loop supply chain network. In the real world the demand and the maximum capacity offered by the supplier are uncertain which in this model; the fuzzy theory discussion was used to cover the uncertainty of the mentioned variables. The objective functions of the model include minimizing costs, increasing revenues of recycling products, increasing cost saving from recycling and environmental impacts. According to the NP-hard, an efficient algorithm was suggested based on the genetic Meta heuristic algorithm to solve it. Twelve numerical problems were defined and solved using the NSGA-II algorithm to validate...

On the other hand, in classic scheduling case, the focus is on balance between time and cost of carrying out projects, which in such a situation, one of possible solutions to shorten time of implementing project is to accelerate activities. This acceleration can affect the quality of conducting projects and environmental impacts, in addition to impose more costs. Hence, in such studies, environmental impacts and quality of activities were also considered as new indicators in case of project time-cost balance. There has been proposed a new mathematical model with four indicators: cost, time, quali-ty and environmental impacts. The provided model is a multi-objective mathematical model of zero-and-one programming type that despite traditional models, in which there is only considered an implementation mode for carrying out activitie...

It helps banks determine customer loyalty, which yields profit making for bank. On the other hand, it is important to know about credit risk of customers with the goal of decreasing loss and better allocation of bank resources to applicants of receiving loan. According to nature of customer loyalty discussion and credit risk, these two issues are separately studied. The present article deals with studying customer loyalty and prioritizing based one private bank in Kurdistan province. The proposed model of this paper studies customer loyalty by using Recency Frequency Monetary (RFM) factor for prioritizing customer based on loyalty properties and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). In addition, in order to calculate the relative importance coefficient or weight of loyalty properties in RFM method, the pair wise comparison matrix based on analytical hierarchy process (AHP) is used. Results show that in the present study, necessarily customers having higher average monetary value during a specified time period does not have much higher priority compared with other customers.

An intrusion detection system (IDS) can limit the access of user to the computer by implementation of some specific rules. These rules are based on the knowledge of the expert. In this research a model is suggested that is based on data analysis with the aim of increasing accuracy. This model consists of two layers. At the first one, the clustering algorithm is used with the aim of simplifying input space and decreasing calculations. At the second layer, classification algorithm is used to classify available samples in the cluster. The results show that this method has a better performance on “KDD CUP” data set in comparison with previous methods. .

Earned Value Management is considered as a technique for answering two following questions: how long does it take to complete a project? How much does the project cost? Project Performance Evaluation can only be predicated based on previous data and knowledge in the present dealings of earned value and its future conditions and prospects would not be categorically realized. Although there are many proposed methods to solve these boundaries, there is not a method encompassing all uncertainties and future conditions. This paper aims at introducing a new method using time limits, costs and project performance in fuzzy logic to determine the earned value indexes. Risk factors are added to the Fuzzy logics in order to obtaining the precise estimation in predicting the final outcomes of the project. This paper provides a brief introduction regarding the current methods followed by investigation on ...

At the same time, social networks have widely been used for commercial purposes. As a result, in order to sell the products, social networks have been equipped with various recommender systems that provide the users with commercial offers that are appropriate for their behavior. The accuracy of the recommender systems in providing offers to the users and the number of offers accepted by the users are crucial issues. In the present study, a recommender system was designed that operates based on the users ' behavior on Facebook and in two phases offers the users to buy their favorite products. In the first phase, the users ' behavior is investigated and based on their interest they are offered to buy some products. In the second phase, the recommender system uses data mining techniques and provides the users with offers that are relevant to their previous purchase. The data of the study are fact...

Given the importance of the chemical industry as a strategic industry around the world, especially in Iran, and its effect on upstream and downstream industries, determining the optimal export diversification strategy in this sector is critical. In this regard, the theory of economic complexity will be used as a basis for identifying high-potential opportunities for export diversity and the theory of product space will be applied which is a powerful tool for identifying strategies. Using export data of chemical products (2014-2018) in 128 countries, we drew product space for Iran. Based on revealed comparative advantages of more than one, results for Iran show that out of 921 six-digit chemical products of the harmonized system, 295 product codes has potential to be activated. Subsequently, by adding two new constraints to the model, potentially activate...

There is a noticeable lack of empirical findings in the literature on the impact of FDI on the accumulation of human capital in developing countries. In this paper, we investigate the relationship between accumulation of human capital and FDI inflows for three ASEAN countries (Malaysia, Thailand and Indonesia) during period 1985 to 2005. We use a new human capital indicator and an econometric method which is based on a panel dynamic method [System generalized method of moments (GMM)], the empirical finding shows FDI inflows has a positive and statistically significant impact on accumulation of human capital in Malaysia, Thailand and Indonesia. Key words: Foreign direct investment (FDI), Human Capital, dynamic panel data.
