A DEA-TOPSIS approach for ranking credit institutions Pages 2071-2076 Download PDF

Authors: Mohammad Ehsani, Abolfazl Danaei

Keywords: Data envelopment analysis, Credit institution, dea, TOPSIS

Abstract:

Measuring the relative efficiency of financial units plays essential role for making strategic decisions such as business development, downsizing, etc. This paper presents an empirical investigation to rank different branches of a credit institution named Samen in city of Semnan, Iran. The proposed study uses data envelopment analysis (DEA) for measuring the relative efficiency of 17 units. The results indicate that five units were efficient and using Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), the efficient units are ranked based on some inputs/outputs. The results of this study indicate that most branches of this financial unit performed poorly and a restructure in their businesses is necessary. In addition, the study has provided some evidences that considering employee wage, bank deposit and administration expenses as inputs for DEA implementation seems to provide better results than using total assets and equities.

A mathematical model for facility location in banking industry Pages 2097-2100 Download PDF

Authors: Amir Ehsani, Abolfazl Danaei, Mohammad Hemmati

Keywords: Banking industry, ATM, Facility location

Abstract:

This paper presents an empirical investigation to determine the efficient locations of bank branch as well as automated banking machine. The study develops a mathematical model to minimize the cost of facility establishment subject to some constraints, which are associated with the population, accessibility of facilities, etc. All input parameters are considered in terms of triangular fuzzy numbers and using some methods, they numbers are converted into crisp values. The method has been applied for four cities in province of Seman, Iran and using WinQSB, the efficient locations of the facilities for a private bank named Samen have been determined.

An application of fuzzy AHP for ranking human resources development indices Pages 993-996 Download PDF

Authors: Mehdi Paktinat, Abolfazl Danaei

DOI: 10.5267/j.msl.2014.3.013

Keywords: Fuzzy AHP, HDI, Human development index

Abstract:

The Human Development Index (HDI) is a composite statistic of life expectancy, education, and income indices, which is implemented to rank countries into different items of human development including life expectancy, education, living standards. This paper uses fuzzy analytical hierarchy process (AHP) to rank five influencing factors including income, culture, healthcare, knowledge and civil rights in Iran. Using a questionnaire in linguistic form, the study asks some experts to make judgment about the relative importance of each pair of five items and it ranks them based on fuzzy AHP technique. The results indicate that income is number priority followed by knowledge, culture, civil rights and healthcare affairs.

Performance measurement of administration services using balance scorecard and Kano model Pages 703-706 Download PDF

Authors: Abolfazl Danaei, Mohammad Hemmati, Marziye Mardani

DOI: 10.5267/j.msl.2014.2.022

Keywords: Administration offices, Balance scorecard, BSC, Kano model

Abstract:

This paper performs a survey to measure the performance of an administration unit in Iran based on a popular technique of balance scorecard. The study also uses Kano model to prioritize various factors and to provide necessary recommendation to improve the performance of different units. The survey has indicated that while these offices do well in terms of financial figures as well as customer perspective, they perform poorly in terms of learning and growth. According to our survey, it is essential to use information technology in general service offices, properly. In addition, these administrative agencies need to use hardware and software packages, more efficiently and these two basic items have received much attraction.

A fuzzy mixed integer programming for marketing planning Pages 493-496 Download PDF

Authors: Abolfazl Danaei, Mohammad Hemmati, Ghazaleh Naseri Kohneshahri

Keywords: IPHONE, GIS system, Marketing planning, Mixed integer programming

Abstract:

One of the primary concerns to market a product is to find appropriate channel to target customers. The recent advances on information technology have created new products with tremendous opportunities. This paper presents a mixed integer programming technique based on McCarthy & apos; s 4PS to locate suitable billboards for marketing newly introduced IPHONE product. The paper considers two types of information including age and income and tries to find the best places such that potential consumers aged 25-35 with high income visit the billboards and the cost of advertisement is minimized. The model is formulated in terms of mixed integer programming and it has been applied for potential customers who live in city of Tabriz, Iran. Using a typical software package, the model detects appropriate places in various parts of the city.

Keywords: Investor behavior, Mutual fund, Tehran Stock Exchange

Abstract:

There are many evidences to believe that investors’ personal characteristics influence on their financial decisions when they purchase stocks, bounds, etc. In this paper, we present an empirical investigation to study the effects of 20 personal characteristics on 52 managers of mutual funds in Iran. Using Pearson correlation test, the study has detected that seven factors including anchoring & adjustment, framing, over confidence, illusion of control, hindsight, recency and self-attribution positively influence on investors’ behaviors. In addition, five factors including consistency, self-control, loss aversion, regret aversion and availability negatively influence on investors’ behaviors. However, the study did not find any evidence to confirm any kind of relationship of representativeness, conservatism, ambiguity aversion, optimism, mental accounting, confirmation and status quo on investors’ behaviors.

Knowledge plays an essential role on creating value added business units in today’s competitive environment. In this paper, we perform a study to investigate the relationship between knowledge management and organization culture in an Iranian PVC industry. The proposed study selects a sample of 65 people and distributes a questionnaire among them. The study investigates the relationship between knowledge management and four organizational cultures’ components including mission, consistency, involvement and adaptability. Using Denison model and implementation of Pearson correlation ratio as well as stepwise regression techniques, we analyze four hypotheses of the survey. The results of the study confirm that there are strong relationships between knowledge management from one side and mission, consistency, involvement and adaptability.

Selecting an optimal mixed products using grey relationship model Pages 1825-1832 Download PDF

Authors: Farshad Faezy Razi, Abolfazl Danaei, Amir Ehsani, Changiz Dolati

Keywords: GRM, Mixed product, MOLP, Supply chain management

Abstract:

This paper presents an integrated supplier selection and inventory management using grey relationship model (GRM) as well as multi-objective decision making process. The proposed model of this paper first ranks different suppliers based on GRM technique and then determines the optimum level of inventory by considering different objectives. To show the implementation of the proposed model, we use some benchmark data presented by Talluri and Baker [Talluri, S., & Baker, R. C. (2002). A multi-phase mathematical programming approach for effective supply chain design. European Journal of Operational Research, 141(3), 544-558.]. The preliminary results indicate that the proposed model of this paper is capable of handling different criteria for supplier selection.
