There are many characteristics in hightechnology project investment, such as needing a lot of capital, having so many unsure factors and so on. There are full of risks in the investment process. Some corporations were disastrous in investment because of ignoring the risk evaluation or using the inapposite valuation methods. So it is necessary to use a scientific evaluation method in the investm...

Joint Admission Control (JAC) handles the admis-sion of all new or handoff service requests in the mod-ern heterogeneous networks and allocates the required resources and guarantees the QoS constraints for the service. JAC is a multicriteria problem in nature, and the usage of MCDM system is mandatory to decrease the influence of the dissimilar, imprecise, and contra-dictory measurements for th...

The extended TOPSIS method is proposed to solve multi-attribute group decision-making problems which the attribute values take the form of interval grey linguistic variables and attribute weight is unknown. To begin with, the relative concepts of interval grey linguistic variables are defined; the operation rules, the properties, and the distance between the two interval grey linguistic variabl...

This paper describes an application of multi-criteria decision making (MCDM) for multi-modal fusion of features in a 3D face recognition system. A decision making process is outlined that is based on the performance of multi-modal features in a face recognition task involving a set of 3D face databases. In particular, the fuzzy interval valued MCDM technique called TOPSIS is applied for ranking...

An Expert System for aid in material selection process is proposed, which in conjunction with TOPSIS(Technique for Order Preference by Similiarity to Ideal Situation) method[l] provides a very effective and efficient technique of material selection for a component. TOPSIS is a highly advanced optimization technique, which requires that user provides relative importance to different properties b...

Due to green legislations, industries track the used products through reverse logistics contractors. A reverse logistics programme offers significant cost savings in procurement, transportation, disposal and inventory carrying. Since reverse logistics operations and the supply chains they support are considerably more complex than traditional manufacturing supply chains, it can be offered to th...

Hesitant fuzzy linguistic decision making is a focus point in linguistic decision making, in which the main method is based on preference ordering. This paper develops a new hesitant fuzzy linguistic TOPSIS method for group multi-criteria linguistic decision making; the method is inspired by the TOPSIS method and the preference degree between two hesitant fuzzy linguistic term sets (HFLTSs). To...

A new approach to the complex problem of objectively evaluating the edge of a professional baseball starting pitcher is proposed to avoid judgments resulting from subjective opinions. The method not only ameliorates the subjectivity of the topic but also provides the means to rank starting pitchers in Taiwan. Entropy and the Technique for Order Performance by Similarity to the Ideal Solution (T...

Properly evaluating the overall performance of tubular scraper conveyors (TSCs) can increase their overall efficiency and reduce economic investments, but such methods have rarely been studied. This study evaluated the overall performance of TSCs based on the technique for order of preference by similarity to ideal solution (TOPSIS). Three conveyors of the same type produced in the same factory...
