There are factors in any system that may act contrary to system order, causing disorder, disrupting behavior, disrupting system stability or entropy, and will significantly reduce employee and organization performance. To explain behavioral entropy and identify the dimensions, indices, and the relationship between them, and finally to present a behavioral entropy model. The research method was exploratory and the data analysis method was mixed (qualitative and quantitative). The qualitative part of the Delphi method consisted of 20 experts including 10 human resources professors and 10 extension managers. Snowball method was used to select both groups. At first, using a qualitative approach, semi-structured interviews were conducted with experts in the conceptual model of research and then to test the model from each of the standard questionnaires, a questionnaire with validity and reliability of 0.814 and 0.74 was set up and in a statistical population of about 1000 managers and 470 staff managers. The Iranian industries were distributed by random stratified method and 441 questionnaires were obtained using quantitative research methods and structural equations of Venice using SPSS and LISREL software. In the qualitative section, 81 components were identified which, according to Kendall's coefficient of 0.811 after four Delphi panel formats, remained 15 components, including three behavioral entropy dimensions triplicates including three individual, organizational and environmental categories. In section: The influence of independent environmental and organizational factors on individual factors mediated by 0.788 and 0.715, respectively, and the effect of environmental and organizational structures on behavioral entropy dependent constructs is greater than the critical values of 1.96 and 2.58, respectively. Direct and meaningful support. The findings indicate that organizational and environmental factors influence individual factors and individual factors have a faster and longer lasting effect on behavioral entropy retention. The implications of behavioral entropy for each of the variables are summarized as disorder, confusion, an atmosphere of instability, abnormal behaviors, reduced productivity, and organization.

The purpose of this study is to provide a behavioral entropy pattern in the organization. This research has been carried out in the framework of qualitative approach and using the research methodology of the Foundation. Data collection tools were semi-structured interviews and interviews were conducted using a targeted sampling method with 23 senior and middle managers of Isfahan municipality and academic experts familiar with organizational issues and organizational behaviors. Data analysis was performed in three stages: open coding, axial coding and selective coding. Based on this, a qualitative research model was designed. In this model, the most important causative factors were individual, organizational and environmental factors. The main phenomenon in entropy was the behavior of organizational injustice. The underlying factors included lack of organizational transparency, inappropriate socialization, lack of comparative leadership and organizational culture. The results showed that the weakness of communication systems, the silence of managers against the hackers and the hypocritical behaviors of managers and employees are the most important factors in intervention. Based on the results of the justification, the escape rule and the non-emotional-mental conflicts are the strategies of individuals in behavioral entropy. Finally, the entropy consequences of behavior were categorized in the form of five individual, organizational, group, family, and environmental consequences.

The purpose of this study is to develop a method and a structure which enable us to evaluate security in e-commerce in different companies by various experts. In this study, Shannon entropy was placed along with Dempster- Shafer theory so that the ultimate level of security could be measured. Considering the fact that in the present study collecting data is based on the decision of a team of experts, data collection procedures were conducted in two phases; in the first phase, data related to determining the weight of measures were collected and in the second phase, the data about the security level of criteria were collected through interview and using a decision team in four commercial companies in Mashhad who were willing to cooperate. Then, the importance of security measures in relation to each other, security level of each measure and the overall level of security in this commercial company were determined. The final results showed that the overall level of security for the three companies is high and one is medium.

Strategic control can provide performance support from decision and strategy. Now, appropriate and role of operations research (OR) for strategic support is proved and model is useful tool for fulfill this role. New field of performance and strategy linkage have suitable capacity for this type of modeling. This paper is tried with using case study Research method in the fields of performance measurement (productivity / financial approach) and relation between performance and strategy and also using DEA and entropy and particular heir combination method (Developed by j. Michael Velayas,1992) and modification of that method, explain theoretical basics of designing S.D.S.M process-functional model that results of its implementation provide ability for top managers of business organizations to support from strategies and strategic decisions.

Time and uncertainty in the strategic planning process play an important role. In today''s changing world، having a commensurate strategy with changing environmental conditions is very important and Classical approaches in strategy fomulation can’t to respond appropriate and quickly to needs of organizations In such a dynamic and uncertain environment. Fuzzy decision tree that is result of combining ID3 algorithm and fuzzy sets theory، provides a systematic model that Organizations can use it to response appropriate and quickly against changes in turbulent environments. Another advantage of this approach is Its ability to work with liguistic variables that resulted knowledge from it، has High understanding for human. This approach due to be fuzzy can to repel with uncertainty and by considering different states in database has appropriate reaction in dealing with environmental changes. this research، At first identify involved main attribute in the strategy fomulation and acts to creat the date base and decision tree with use of entropy calculating to be achieved rules base. Finally، to be fuzzy making inputs and outputs، fuzzy inference system offers precedences strategies.

In IRI Vision 2025 document, achieving economic outlook is pressed, but it requires establishing necessary infrastructures regarding to particular economic condition of the world in present age. One of these important infrastructures in order to achieve economic growth and development is Doing Business. In this paper, by using annual data of Doing Business -of an Institute affiliated to the World Bank- and the TAPSIS Technique as well, we have initially drawn ideal point of Doing Business in the present region of IRI Vision 2025, and have determined the gaps between present situation and ideal situation within all sub-indexes. Then, through Entropy Technique and based on the importance of each index of Doing Business in the region, we have prioritized the indexes to be encountered with senior operators of the state as an action guide, and to make strides toward conquering the region's economic summit by improving Doing Business indices in order to achieve the objectives contained in the IRI Vision 2025.

National competitiveness as a platform for economic prosperity, attaining higher levels of welfare and living standards has attracted ample attention of both governors and scholars during the past decade. As a result of this attention, Global Competitiveness Index (GCI) of the World Economic Forum consists of twelve pillars, each of which addresses a certain (hardware or software) aspect of national competitiveness. This study aims at investigating the relationship between the pillars of GCI and economic prosperity in order to use that information for presenting a model to improve national competitiveness in Iran. We used the canonical correlation analysis (CCA) to identify the pillars that have more relevance in establishing the particular relationship between national competitiveness and economic prosperity, then we prioritized them by Entropy technique. Canonical correlation analysis on data from 139 countries shows that Technological readiness,Infrastructure and Higher education and training are respectively the most important pillars that affect Iran’s economic prosperity.

The main purpose of this research is review and analysis of spatial equilibrium degree in East Azerbaijan urban system based on entropy index and class difference limit model underlying of statistics and information of 6 periods of census.

Method of research performance is the form of quantity-analytical parallel with presenting of practical models. Mentioned statistical society in this research is the cities of case study province that formally enunciate as a city in census.

In 1385 reducing of share of Tabriz population has reached to 58.19 percent. Also share of province great cities population have faced with reduction but because of number of province cities have reached from 39 cities to 57 cities and also the number of small cities and low population have raised more. Therefore because of rising number of small cities the reduction of Tabriz population share comparison with whole of province population renews exaggerate and entropy degree has reduced to .502.

The conclusions of this research reveal that settling of population in centers and city classes have distributed with equilibrium form and concentration process of Tabriz metropolis is streaming with noted speed and have directed city network from semi equilibrium situation to crisis conduction.

Surveying the supplying market, as well as choosing the most proper supplier, is one of the most important activities in every organization and company. Neglecting the conditions of parts and raw material supply or disregarding cooperation with the suppliers would lead to an increase in purchase costs, quality control costs, and quality guarantee costs. All the mentioned costs would eventually make the customer dissatisfied with the final goods and services. In ranking the suppliers and choosing them as suppliers, several criteria and factors should be considered.
In this paper, in order to rank and evaluate the suppliers of Iran Tractor Manufacturing Company (ITMCo), we have studied the methods and models of multiple attribute decision making, and eventually, have chosen the proper model. The research population consists of the experts of parts-supplying department of ITMCo.
First, the important criteria evaluating and ranking the suppliers of ITMCo. Were determined based on library Study and interviewing the experts. Then, by using a questionnaire and based on the Shanon Enteropy Method the importance rate of each criterion was specified.
Studying the multiple attribute decision making models showed that TOPSIS model is the most suitable model for ranking the suppliers of ITMCo.
The parts needed in ITMCo in 2005 (1384) are divided in to 6 main categories: 1) Completed forged and cast parts
2) Completed parts
3) Completed machined parts
4) half-completed forged and cast parts
5) half-completed sheeted parts
6) half-completed machined parts.
Since studying all the mentioned groups is not feasible in this paper, we have confined our study only to the ranking of the suppliers of the first category, the completed forged and cast parts.
