Considering of the shortage of the limits of the ordinary GM (1, 1) model, a metabolic GM (1, 1) model is established to predict the amount of the outstanding debt of local government and GDP (Gross Domestic Product) throughout the years. And then debt ratio is used to evaluate whether Chinese government's financial position is healthy, revealing the balance of government debt at the end of 2015 accounts...
Facility layout problem (FLP) which deals with the placement of facilities in the plant area is one of the most critical problems in manufacturing systems design. This paper presents a novel facility layout approach based on differential evolution (DE) algorithm. Firstly, mathematical model with constraints for the FLP is established. Then, a new facility layout algorithm based on DE is proposed,...
Facility layout problem which deals with the placement of facilities in the plant area is one of the most critical problems in manufacturing systems design. However the facility layout problem is one of the combinatorial optimization and nondeterministic polynomial complete problems, and obtaining an optimal solution for the large-sized facility layout problem in reasonable computational time using...
According to the limitations of Three ratio method in Gas chromatographic analysis of transformer, uses radar chart to show the relative content of gases dissolved in oil intuitively, sets up the typical radar chart modeles of fault type. Calculates the similarity of binary images of the radar chartes prepared to be tested and typical modeles of fault type, to export the probability of some failures,...
