Modular product evaluation is one of key technologies in modular design. Three kinds of evaluation methods, which based on three modular design styles, were proposed in this paper. These methods integrated customer satisfaction index (CSI), product customization index (PCI) or modularity degree index (MDI). Then several modularization customized products can be evaluated. Some customer satisfaction...
A approach is suggested for designing and developing a trade surplus influence factors correlation analysis application where GMDH principle is used for generating it more easily. This approach uses self-organizing data mining importing the concept of evolution based on principle of GMDH and enables the knowledge extraction process on a highly automated level and generates optimal complex model in...
This paper proposes a new method to deal with directional technology distance function. We propose a new concept: partial directional distance function, which describe the distance of one element (including inputs, outputs, desirable and undesirable) in their direction given the partial distance of the other elements. Based on this, we present the multi-goals programming problem and its solution arithmetic...
