Purpose: To reduce the subjective prejudice and uncertainty in evaluating product quality. Design/methodology/approach: AHP method is used to analyze the structure of product quality evaluation problem and determine weights for evaluation criteria. After structure judge matrix, sequencing calculation and concordance examination, evaluation methods such as fuzzy synthesis evaluation are used to ...

Neicu et al. observed experimentally spontaneous formation of the long-range orientational order and large-scale vortices in a system of vibrated macroscopic rods. We propose a phenomenological theory of this phenomenon based on a coupled system of equations for local rods density and tilt. The density evolution is described by the modified Cahn-Hilliard equation, while the tilt is described by...

In evaluating housing projects, developers often have several sites as alternatives for development. Assessing each site so as to identify the best for implementation is their most important decision in the project planning stage. The traditional net present worth method has difficulty in including intangible benefits and risks, so the result of it may not represent the overall value of an alte...
