A finite time horizon inventory problem for a deteriorating item having two separate warehouses, one with an own warehouse (OW) of finite dimension and the other with a rented warehouse (RW), is developed in fuzzy environment. Due to different preserving facilities and storage environment, inventory holding cost is considered to be different in different warehouses. The demand rate of item depends on the selling price and is displayed stocked level in own warehouse. Shortages are allowed and backlogged them partially, which depends on the duration of stock out. The stocks of RW are transported to OW in continuous release pattern. Due to impreciseness in nature, total revenue and shortage cost are assumed to be imprecise in nature too. By using the fuzzy goal programming method, multi-objective problem is converted into single objective function. The model is illustrated numerically and the results are presented in tabular form.

In this paper, an inventory model of two-warehouse is considered, which evaluates the impact of a reduction rate in the selling price with volume flexibility. In real life, there are many products, which may decay or deteriorate or become obsolete. Therefore, one alternative is to clear the stock by selling a large amount of items at reduced prices. Taking this concept into account, this paper considers a fixed demand rate at the beginning of planning until the certain time point occurs, while demand is assumed to follow the pattern of nonlinear and non-decreasing power function of the reduction rate. The total cost function includes warehouse and rented warehouse holding costs, set up cost and the production cost. Numerical illustrations are given to exemplify the model and the proposed model is solved using a Genetic Algorithm (GA) with sensitivity analysis.

This paper examines the effect of the service brand on the customer value–loyalty process. The study includes the traditional effect of brand image plus three additional influences, which reflects the broader service perspective including company image, employee trust, and company trust. Using survey data of a sample of 385 bank customers, the analysis indicates there is a direct influence of some of the perspectives of the brand on customers & apos; perceptions of value. The results indicate that brand image, organization image, trust to firm influence positively on quality of services. In addition, brand image, organization image, quality of services and trust to firm influence on customer’s perspective where quality of services maintains the lowest impact and corporate image has the highest impact on customer’s perspective.

This paper investigates consumer involvement profile among people who intend to purchase mobile devises. The study considers the effects of various factors influencing on purchase intention including consumers’ personal characteristics such as age, gender, income as well as some external factors including advertisement. The study uses a questionnaire in Likert scale, originally developed by O’Cass (2000) [O’Cass, A. (2000). An assessment of consumers & apos; product, purchase decision, advertising and consumption involvement in fashion clothing. Journal of Economic Psychology, 21, 545-576.]. The questionnaire has been distributed among 385 people, randomly who purchased mobile devices from a mall in city of Tehran, Iran. Using Pearson correlation test, the study has concluded that oral advertisement as well as consumer purchase involvement have positive and strong relationship with consumer’s purchase intention. In terms of age, people aged 20-30 maintained the highest purchase intention. In addition, in terms of gender, men had more purchase involvement than women did.

This paper investigates the role of export competitive advantage on export performance in food industry. The proposed study designs a questionnaire in Likert scale and distributes it among 280 randomly selected experts in food industry and Cronbach alpha has been calculated as 0.827. The study has applied factor analysis to find important factors influencing export performance. Kaiser-Meyer-Olkin Measure of Sampling Adequacy and Bartlett & apos; s Test of Sphericity have been performed to validate the results and they both validated the questionnaire. The results of the survey have determined six effective groups including product development, e-commerce, marketing planning, organizational performance, competitiveness and supply chain management.

This paper investigates the effects of three components of organizational justice on development e-banking in one of Iranian banks. The proposed study uses two questionnaires, one for measuring the effects of organizational justice and the other for e-banking in Likert scale. Cronbach alphas for organizational justice and e-banking are calculated as 0.831 and 0.749, respectively. The study has been implemented among 385 regular customers of an Iranian bank. Using Spearman correlation ratio as well as stepwise regression analysis, the study has detected that two components of organizational justice including distributive justice and procedural justice influence on e-banking, positively.

This paper presents an empirical investigation to study different factors influencing auto parts in different regions of Iran. The study has asked some experts who worked for the biggest auto parts supplier named SaipaYadak to express their insights about important factors influencing demand for auto parts in different region and their insights have grouped into four categories of parts related issues, weather conditions, regional as well as cultural factors. The study has been applied in five different regions of country including central, south, north, west and east. The study has used analytical network process (ANP) to rank different factors and the results indicate that regional factors is the most important item followed by cultural issues, auto parts and weather conditions.

This paper presents an empirical investigation to study the effects of macro-economic factors on the performance of stocks listed on Tehran Stock Exchange (TSE). The proposed study considers the effects of money supply, inflation rate, oil price, unforeseen changes in the course structure of interest rates as well as unanticipated changes in industrial production on stock price. Using seasonal information of stock price over the period 1997-2007 as well as regression analysis, the study has determined that risk premium of unforeseen changes in the course structure of interest rates, money supply, inflation rate and unanticipated changes in industrial production are meaningful when the level of significance is five percent. In other words, Arbitrage pricing theory model describing the expected return per share is reasonable and macro-level variables explain systematic risk on TSE.

The new era introduced as a technology era, is important as promising of a new world with modern methods in better and more useful teaching, which result in progress in qualitative teaching of students in education. The aim of the present study is to learn more about the effect of electronic courses in mathematics on students’ social growth, cognitive growth and the quality of learning. Statistical population includes 55 teachers of junior high school in city of Khash located in south part of Iran, selected randomly based on Morgan Tables. To gather data, social growth, cognitive growth and learning quality questionnaires were used. To analyze data one-way analysis of covariance (ANOCOVA) test was used. The results reveal that electronic educational courses were effective on social growth and cognitive growth but not on learning quality.

This paper investigates the effects of different marketing strategies including basic marketing, reactive marketing, accountable marketing, proactive marketing and partnership marketing on brand equity. The proposed study uses two questionnaires, one for measuring the effects of different marketing strategies and the other for brand equity in Likert scale. Cronbach alphas for brand equity and marketing strategies are calculated as 0.71 and 0.86, respectively. The study has been implemented among 385 regular customers of a Picnic Gas distributer in city of Karaj, Iran. Using Spearman correlation ratio as well as stepwise regression analysis, the study has detected that there were positive and meaningful relationship between marketing strategies and brand equity.
