Study on the Model of Fuzzy Optimization and Its Application for Variant Projects in Railway Location

The conventional method of optimal selection of variant projects of railway location is based on lowest investment costs and operating expenses. An optimal project is usually proposed after analyzing qualitative factors of variant projects. However, it is difficult to select the optimal project if the differences of economic indices of variant projects are not big enough and the qualitative factors of variant projects have alternative advantages over one another. This paper considers the optimal selection of variant projects in railway location as a process of multi-objective fuzzy optimization. A decision making model of multi-objective fuzzy optimization is established and an application software for an engineering project is developed.
