The process of multiple criteria decision making (MCDM) is of determining the best choice among all of the probable alternatives. The problem of supplier selection on which decision maker has usually vague and imprecise knowledge is a typical example of multi criteria group decision-making problem. The conventional crisp techniques has not much effective for solving MCDM problems because of imp...

Machine tool selection is a very complex procedure. It involves deep analysis of various factors affecting functioning and performance. CNC machine tool selection is also a such kind of problem[5]. Objective of this study is to perform various MCDM methods for selecting most appropriate machine tool. AHP method is used to calculate the weights of various criteria[10] . The numerical problem con...

Research puts forward perception-based cognitive workload evaluation methods to help VR developers and users measuring their when playing with a application. Approaches measure based on biosensors have progressed significantly, while subjective still rely standard questionnaires such as the NASA-TLX table, Subjective Workload Assessment Technique Modified Cooper Harper scale. The pre-defined qu...

Abstract: With the globalization of online shopping, deterioration of the ecological environment and the increasing pressure of urban transportation, a novel logistics service mode—joint distribution (JD)—was developed. Selecting the optimal partner combination is important to ensure the joint distribution alliance (JDA) is sustainable and stable, taking into consideration conflicting criteria....

There are usually more requirements than feasible given valuable ones for implementation in order to ensure the delivery of a high value system. Simple prioritization approaches like 110 ranking or MoSCoW lead to numerous ties requiring one to repeat the process for the tied items. In a previous study [1] we analyzed 17 different prioritization frameworks that could be used to perform value-bas...
