This paper investigates recent techniques that have been developed for optimization of linear programming problems. In practice, there are many problems in which all decision parameters are fuzzy numbers, and such problems are usually solved by either probabilistic programming or multi objective programming methods. Unfortunately all these methods have shortcomings. In this paper, using the concept of comparison of fuzzy numbers, it is introduced a very effective method for solving these problems. With the problem assumptions, the optimal solution can still be theoretically solved using the simplex based method. To handle the fuzzy decision variables can be initially generated and then solved and improved sequentially using the fuzzy decision approach by introducing Robust’s ranking technique. The model is illustrated with a case study application. The proposed procedure was programmed and through MATLAB (R2009a) version software, the four dimensional slice diagram is represented to the application. Finally, the real case problem is presented to illustrate the effectiveness of the theoretical results, and to gain additional managerial insights for decision making.

An Empirical Study of Consumer Ethics: A Comparative Study of Two Firms of Faisalabad, Pakistan

by Khaliq Ur Rehman Cheema, Nasir Imtiaz and Yasir Shafiq

Original Research

Ethics are very important factor in today business. We have conducted this study to identify consumer ethics and their buying behavior in Particular two Organizations of Faisalabad, to study the consumer ethics we used four different dimensions. The purpose of this paper to find the situation in which consumer behaves unethically in Pakistan. And the result compares with previous consumer ethics researches. It is an exploratory research for the purpose of seeing the consumer ethics. The study shows that different consumers behave differently in term of ethical point of view. Our study shows that customers similar in terms of Machiavellianism they display. Limitation in this paper is that the study was conducted only in Faisalabad. Another problem is that time; willingness and mood of the customers also affect the responses. This is an exploratory research and the results are not claimed to be generalized. So the further research should be made on social and political problems which affect the ethical behaviors and try to generalize the results.
