Application of GMDH-type neural network to stock price prediction of Iran's auto industry

There are many backward and forward linkages between automotive industry and other industries because of technical and structural properties of that. After the oil industry, the automotive industry is one of the largest and most profitable industries in Iran. Also, this industry has received government extensive attention in order to become competitive. Thus, development of Iranian economy is closely related to the competitive advantage of Iranian automotive industry. So, owing to the importance of this matter, we have tried to develop a Group Method of Data Handling (GMDH) type neural network for stock price prediction of automotive industry. For stock price prediction by the GMDH-type neural network, we are using earnings per share, prediction earnings per share, dividend per share, price-earnings ratio, earnings-price ratio as input data and stock price as output data. For this work, data of eight automotive companies are gathered from Tehran Stock Exchange. The GMDH-type neural network is designed by 80% of the experimental data. For testing the appropriateness of the modelling, reminders of primary data were entered into the GMDH network. The results are very encouraging and congruent with the experimental results.

Optimal design of adaptive neuro-fuzzy inference system using genetic algorithm for electricity demand forecasting in Iranian industry

Demand planning for industrial's electricity consumption is an important factor to efficiently plan the generation and distribution of power utilities. However, this can only be possible if the demand is predicted accurately. Recent advancement in adaptive neuro-fuzzy inference system aimed at mapping input to output for highly non-linear processes such as energy management field, provide reliable approach to forecast energy demand. Despite the wide range of applications and flexibility of adaptive neuro-fuzzy inference system, complexity of the rule base is featured with certain limitations associated with combinatorial explosion of rules, parameters and data. This paper proposes a hybrid procedure, subtractive clustering technique coupled with genetic algorithm, to develop adaptive neuro-fuzzy inference system. Genetic algorithm finds the optimum value of cluster radius which guaranteed the minimum number of rules and error. The empirical data regarding the industrial's electricity demand in Iran from 1967 to 2011 are investigated to demonstrate the applicability and merits of the present method. The performance of hybrid approach is found to be better than that of conventional adaptive neuro-fuzzy inference system based on gird partitioning, fuzzy c-means, and subtractive clustering in terms of both accuracy and the number of rules.

The strategies and the factors that influence technology acquisition channels. Case study: Iranian die-making industries

In recent years, technology has played a significant role in the development of many countries and in the creation of wealth for individuals as well as corporations. Literature shows that, in normal conditions, several factors influence the acquisition, the implementation and the success of a certain technology. Those factors may differ depending on the country acquiring the technology or the acquired technology itself. Understanding the optimum match between a country or an industrial firm operating in that country and a particular technology is very useful for investment decisions. This paper presents the factors that influence the selection of an appropriate technology acquisition channel. To illustrate this process a case study of Iranian small and medium die–making industries is investigated using the grounded theory. The data used in the analysis is collected through in–depth interviews with many S&M Iranian industries. The results of the investigation indicate that there are new factors that have not been mentioned before in the literature. Furthermore, the complex interrelationships between those factors are outlined. The proposed model has been validated by those who participated in the interviews and the experts consulted herewith.

The relationship between organizational ethical culture, loyalty and customer service quality with mediating role of job satisfaction in Iranian insurance industry environment

Insurance organizations have experienced many changes in competition within the past few years. With the passing of the Gramm-Leach-Bliley Act (GLBA) in 1999, the number of institutions providing insurance has increased and competitors are much larger and stronger (Hogan, 2 001). The Internet has also brought about new competition and concerns. In today's competitive and ever-changing environment, it is essential for organizations to maximize efficiency and provide excellent customer service. This is especially true for insurance organizations with the many challenges they are facing. The insurance industry is experiencing new and changed competition, evolving technology, increased concern and skepticism when selling a non-tangible product, and major regulatory changes.

A New Two-phase Approach for Holding the Strict Positivity Restriction of Weights in DEA Models

Abstract Data Envelopment Analysis (DEA) is a well-known non-parametric management science approach for measuring relative efficiency of decision making units (DMUs) performing similar tasks in a production system that consumes multiple inputs to produce multiple outputs. This approach evaluates efficiency score of a DMU as the maximum ratio of the weighted sum of outputs to the weighted sum of inputs subject to the condition that corresponding ratios for each DMU be less than or equal to one. From the theoretical and the computational points of view, strict positivity of the weights is an important and controversial condition to identify an efficient DMU. One significant method to achieve this condition is considering a positive lower bound on weights, known as non-Archimedean infinitesimal epsilon, nevertheless under some conditions the selected value for epsilon is quite small (sometimes even smaller than the zero tolerance of the computer). There is a two-phase approach which evaluates the efficiency of DMUs in envelopment model without determining a suitable value for epsilon, however it fails to give us a set of positive weights. In fact, finding a set of positive weights among all alternative solutions of multiplier model is a technical challenge in DEA. To meet the challenge, we propose a new two-phase approach which deals with multiplier model and determines positive weights, if there are. A case study of Iranian banking industry is taken as an example to illustrate the potential application of the suggested approach.
