Aiming at current water resources utilization situation of Nanjing, the main indicators that would have an impact on the sustainable utilization of water resources of Nanjing is analyzed in this paper. According to the contribution of the indicators to the system, three-index method is used to determine influence degree of each indicator to the evaluation object and the weight of each indicator, and...
According to theories of Poisson process, compound Poisson process, fuzzy random and product R&D, the fuzzy random forecasting problems on capacity and successful time of enterprise product R&D have been studied, a series of fuzzy random forecasting formulas have been obtained, theories and methods have been put forward to the study of capacity and statistical rule of enterprise product R&D.
The conventional tiers analysis seems to be insufficient and imprecise to capture the importance of building materials' optimization. This paper aims at applying the comprehensive evaluation system in new economic village building materials, and makes the influence factors which are neither clear defined nor easily quantitative being quantification, then make a fuzzy comprehensive evaluation to get...
In this paper, the characteristic index vectors, positive and negative ideal characteristic index vector of fuzzy numbers are defined, based on the characteristic quantity of fuzzy number.Then, the ranking index is proposed according to the given fuzzy numberpsilas linear weighted distance between characteristic index vector and positive /negative ideal characteristic index vector, respectively.Finally,...
