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.

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.

This research is an attempt to suggest a new financial statement analysis method. In this method, the value of accounting information in balance sheet is measured by information theory. Henry Thiel (1969), applying the information theory in accounting; offered a new thought in financial statement analysis. He measured the value of financial statement information by using entropy. Entropy is a logarithmic measure of the rate of transfer of information in a particular message or language. In this research, we attempted to measure the value of information in alimentary corporations’ balance sheet by using entropy and suggested a new method for optimizing fixed assets classification, which increases the information value of those balance sheets. The results showed that if firms present fixed assets information by detail in the balance sheet, the entropy of information will increase and the high value of transmitted information will improve decision making by users of financial statements.

At the age of continuous advances, the times of value added, the age of numerous activities with limited facilities, and finally, the times of productivity enhancement, an improper system of performance appraisal could be an important deficiency. In this article, in order to prevent the cosequences of the unfavorable appraisal system in East Azerbaijan Branches of Islamic Azad University, we have tried to present a model of fuzzy tree to investigate the methods of the performance appraisal of the employees and to select, on the basis of this model, the right performance appraisal method for each branch. To do this, first the researchers recognized the effective factors in identifying the method of the performance appraisal, and then, by using these factors, the performance appraisal methods of employees was investigated. In this regard, the viewpoints of professors and the experts of human resources management have been used. By using the knowledge obtained from the experts of human resources management, a knowledge base was created, and through the use of the knowledge base and algorithm and fuzzy sets, the model of fuzzy tree was offered. Then by distributing the questionnaire, the values of each variable (the effective factors in identifying the performance appraisal method) for each branch were identified. Ultimately, by using these obtained values, the priority of the methods of performance appraisal for each branch were specified. Later, by applying the fuzzy multi-criterion decision making, the researchers identified the priority of selecting the appraisal methods for each of these branches on the basis of decision value.

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.

This paper extends a kind of evaluation process based on fuzzy TOPS IS approach. By focusing on determining the importance and weights of criteria which are effective on decision making, then selecting by lean on Anthropy and eigenvector methods in which comparison between criteria are linguistic and by achieving the weights we try to show the importance for criteria. The application and the mix of several methods in this paper are used to choose the best tickicide and to rank the available alternatives.
