An integrated method for ranking of risk in BOT projects

In BOT approach, the private sector is granted a concession to plan, design, construct, operate and maintain a project in a certain period of time and after that it should be transferred to the government. In this paper, at first the risks of the BOT projects are identified, then we rank the risks based on their severity and effect on project objectives (time, cost, quality, safety and environmental) by two methods, namely FTOPSIS and FSAW. In the next stage, obtained results by NGT method are integrated. Afterward, the occurrence and detection values of each risk are determined by experts and ultimately the risks are evaluated according to risk priority number (RPN) of failure mode and effect analysis (FMEA) technique. Finally, an example is shown to highlight the procedure of the proposed method at the end of this paper

A Fuzzy AHP Model in Risk Ranking

The signification risks associated with construction projects need special attention from contractors to analyze and mange the risks. Risk management is the art and science of identifying, analyzing and responding to risk factors throughout the life cycle of the project and in the best interest of its objectives. In proposed model, we firstly identify risks in the construction projects and suitable criteria for evaluate risks and then structure the proposed AHP model. Finally we measure the significant risks in construction projects (SRCP) based on the project’s objectives by using fuzzy analytical hierarchy process (FAHP) technique.

Investigating the effective factors on electronic trade by viral marketing

This paper performs an investigation to explore a number of strategies underpinning virtual marketing. The study also provides several suggestions for marketers seeking to use viral marketing to position brands or to change a brand’s image, to encourage new product trials and to increase product uptake rates. In this article, we investigate the effect of external factors such as capturing the imagination, targeting credible sources, leveraging combinations of technology and easy to use product on virtual marketing. In addition, the study considers internal factors such as inclusion (the need to be part of a group, the need to be different) and affection on viral marketing. The survey has been accomplished among 140 Iranian people, who were familiar with virtual marketing and they are selected, randomly. Using Pearson correlation as well as regression analysis, the study provides some evidences that there were some positive and meaningful relationship between some internal/external factors and virtual marketing
