This research examines coordinated decisions in a decentralized supply chain, consisting of one supplier and one retailer, which face random demand of a single product with a short life cycle. This paper considers a setting where the retailer has accurate demand information while the supplier does not. Such a problem with asymmetric demand information can be viewed as an extension of the newsboy problem in which both the supplier and the retailer possess the same demand information. Combining the mechanism of quantity discount and return policy will enable us to develop one coordinated model in contrast with the basic and uncoordinated model. Then, optimal order quantities of retailer and profits of supply chain are calculated and compared in each models. Analytical and numerical results show that performance of coordinated model is better than basic and uncoordinated model. This article also shows that coordinated mechanism increases profits of retailer, supplier, and total supply chain.

One of the forms of safety analysis is to examine the events. Several goals are followed in this process. The first goal is to prevent future accidents and the second goal is to identify factors that cause accidents and injuries. Approximately, fourteen thousands occupational accidents occur for industrial workers in Iran annually while the main cause is the human factor. Occurrence of such events effect economic indicators, as well as human wastes. So, the effect of individual factors on the occurrence of occupational accidents in Yazd province is considered. This descriptive study is a cross-sectional survey investigating those incidents occurred in period between 1383 to1385. Results of Spearman correlation analysis show that there is a high correlation between such variables as “age”, “occupational accidents”, as well as the variables like “work experience” and “occupational accidents”. The most traumatic accidents occur for workers between 20 to 30 years old whose work experience level is under 5 years. Besides, the correlation between education level and occupational accidents is low. Finally, using AHP method, these factors were ranked to obtain the necessary and appropriate solutions based on the results.

The purpose of this paper is to study the relationship between employees knowledge management and construction projects performance in Iran. The purpose of the study and collecting data determined the methodology of the research as a survey. Data were collected with a questioner and confirmatory and exploratory analysis methods were used to analyze the obtained data by using SPSS 17 and Lisrel 8.5. The construction consultant companies whose names are listed in their association website have been considered as the society of the research. Using the sampling formula, the number of samples was extracted to 246 samples from which 192 responses were received. The results of the research show that there is a positive relationship between employees’ knowledge and construction projects performance. Therefore, knowledge management can lead to construction projects success.

One of the current issues of industrial investments in the world is advent of various problems which the environmental catastrophe is one of the most common one triggering negative consequences and outcomes in the performance of industrial units' activities. Presenting the model of green industrial clusters, in this research, we immersed to survey the combination of green marketing with industrial cluster to demonstrate techniques of overcoming the environmental crises of country. Since qualitative approach seemed suitable for various questions and objectives of the research, we utilized it for selecting samples, collecting and analyzing data, reaching a conclusion and answering the research questions. The methods for collecting data were limited to discussions, documents and interviews. Since the method of sampling was purposeful, saturation theory was utilized for defining the size of sample. Experts from ministry of industries, mines and commerce, small industrial organization and firms in industrial towns of Iran were interviewed. Therefore, the results demonstrated that all three factors, namely, green productivity, technology of clean production, and green management, can provide a way to approach towards the green industrial cluster.

This research assesses the impact of sales promotional tools, namely coupon, price discount, free sample, bonus pack and in-store display, on product trial and repurchase behavior of consumers. The study aims at investigating the effect of these tools as an element of marketing mix with consumer's decision. The results are supposed to help manufacturer and retailers to improve sales percentage, as well as production. Questionnaire used as a suitable method of research to conduct data collection. Data analysis of this research has been done in two levels: descriptive statistics and inferential statistics. Frequency, percentage, mean and standard deviation are used in descriptive statistics, and Pearson coefficient of correlation is used in inferential statistics. The sample points for the research were foodstuffs buyer in Refah chain stores in Isfahan. A total of 330 randomly selected customers were surveyed using structured questionnaire, out of which, 303 usable responses were received. Then, using SPSS and coefficient of correlation, the relationship between independent and dependent variable was examined and hypotheses were tested. The results show that using free sample and in-store display are proper means for encouraging consumers to product trial, while price discount and coupon can boost repurchasing behavior. Considering the shelf life of product and the type of advertising it needs, manufacturers and retailers can use the above tools to promote their product and sale and also to get the best return.

Control Objectives for information and related technology (COBIT) has become one of the most important guidelines for ITG, which provides organizations with a useful tool to start evaluating their own ITG systems. Since COBIT is a generic framework for any organization, it is crucial to prioritize the domains and processes of the framework based on the organization requirements.The COBIT framework was used to verify if IT processes are correctly managed in Sazehgostar Saipa Co. This research aims at identifying the situation of IT processes through evaluation of processes gap into optimum level based on COBIT Framework. Research questions were as follows: 1.what are the levels of COBIT processes maturity and domains maturity? 2. The processes gap into optimum level. 3. The weights of COBIT processes and domains based on IT strategies. 4. The prioritization of processes gap. The research steps were done based on research model using IT experts’ view and MCDM methods.The results of research show that the corporation is powerful in “Acquire and Implement” and “Delivery and Support” domains more than other domains and the overall maturity level is 1.66. Besides, the results of gaps and prioritization of them in domains show that the most gaps are in “Manage Quality”, “Enable Operation and Use”, “Manage Problems” and “Provide IT Governance” Processes.

Human capitals are the key to success in the knowledge based economies where competitive advantages are the only distinction of the organizations. In fact, among all the three prominent elements of knowledge management (i.e. Human, Process, Technology), knowledge based human resources are invaluable in any organization. Hence, human resources, knowledge and experience should be handled appropriately in a way to have a competitive economy and industry. The present study is aimed at the identification of different prospects of knowledge based human resources in the Iran Khodro company. Using the Estovart elements including: creativity, self-confidence, need to achievement, learning, thinking, self-motivating, flexibility, job mobility and independency, conceptual models were extracted to study the Iran Khodro company systematically. Collecting all the data via questionnaires, the implemented method was based on a survey research. Expert staff in a unit of Iran Khodro Company called Gataat Peresi Production were selected and considered as the statistical set. The entire major and minor hypothesizes were confirmed except independency. In the end, some suggestions for identification, recruitment, maintenance and actuation of the efficient knowledge based human capitals were presented to the authorities of the company.

This research aims at conducting a survey about necessity of organizations' attention to their concerns in the society. To exit from the semantics uncondensed and structural framework of the organizational social area, this research tries to define the basis to solve the problems and actions in the applicative, strategic and fundamental ways. Among these, the expression of corporate social responsiveness is counted as an escape to exit from this confusion. The purpose of the research which is based on developmental application and the determined method is correlation via factor analysis. Sampling done by using Delphi technique was collected the data from elites and by questionnaire not necessarily based on randomly selecting.Recounting growth and genetic way of the expression of corporate social responsiveness, the research pays attention to the conceptual expansion with the triple factor analysis using LISREL software. In the first place the relation of indexes is tested, while in the second and third stages the relationship between components with the dimensions and the relation between the dimensions with the concept of corporate social responsiveness were tested respectively. This research provides a model for Iranian organizations in order to have an operational system in our country. This model identifies dimension, component and index too.

The main objective of this research is to investigate the relationship between cash conversion cycle and liquidity ratios in Iranian companies' context. The study indicates that there is a positive correlation between cash conversion cycle and quick and current ratios. Cash conversion cycle can be defined as a technique to evaluate the working capital indicating the average of liquidity situation of a company. Therefore, statistical population of companies listed on Tehran Stock Exchange (TSE) was examined in this research. Using randomly sampling, 180 companies were selected as the research sample. The research hypotheses were tested by correlation and regression methods. The findings demonstrated a positive strong significant correlation between cash conversion cycle and quick ratio; however, there is no significant correlation between cash conversion cycle and current ratio. There is, also, a negative significant correlation between cash conversion cycle and inventory conversion period. These results imply that quick ratio is a strong indicator for company liquidity; nonetheless, inventory has a negative effect on liquidity.

We could probably consider providing change as the most significant and troublesome issue in an organization. This is because organizations have to keep up with the constantly changing environment of the present market in order not to be dragged to abolition. Due to the importance of change in an organization, business-related ones in particular, considering theoretical and practical preparations seems necessary. This paper aims to bring the influence of change management on IT and business into heed. In order to do so, first we will define what change management is, and provide the corresponding paradigms, and then take a look at the reasons why change is resisted. Finally, the relationship between change management, business and IT will be discussed and deliberated with the provision of a pattern.
