Structuring a corresponding performance assessment index system by dividing the responsibility main body,and selecting a performance assessment index according to the principal component analysis. Then basing on a comprehensive performance assessment which is obtained by fuzzy comprehensive evaluation method, to structure a performance assessment model of supervising public projects that is perfect...
A global optimal mathematical model of increasing pressure for large-scale territorial gas pipeline network is established, and it takes maximum annual benefits of pipeline network system as objective function after comprehensively considered the upstream gas producing conditions, the downstream gas utilizing conditions, the balance equation of nodal flow capacity, and the power, amount, position...
Under the limit of engineering investment, the aseismic optimum design of pipeline system is used to minimize the sum of aseismic cost. Since optimal problem is an nonlinear hybrid model which involves dual "curse of dimensionality" during the mathematical programming and system reliability calculation, traditional optimal techniques can hardly solve the problems of distribution of aseismic...
Diversified electronic money products are emerging recently with the rapid growth of e-commerce in China. A hot research topic now is to identify the dynamic impact arising from various uncertainties of e-money evolution, which is essential for an effective regulation. This paper gives e-money a formal definition, and puts it into two categories according to legal tender dependency. Detailed discussion...
