For a problem with performance functions which include random variables with fuzzy distribution parameters (FDP), it is important to evaluate their reliability accurately and rapidly.

Reordering newsboy problem with stochastic-fuzzy parameters;

Based on analysis of the optimization tools of ANSYS programmer,a set of methods for back analysis of fuzzy parameters for the hydraulic structure were proposed,in which secondary development of ANSYS programmer was the core,and probability analysis was the foundation.

This paper proposes a fuzzy concept lattice model, and suggests a method in which a select window is adopted for cutting the membership degrees in fuzzy formal context, two fuzzy parameters, σ and λ, are defined.

A new fault location algorithm for hybrid transmission line based on distributed parameter model

From basic thermophysical laws,a steady distributed parameter model of an air-conditioning condenser was constructed,in which R22 was taken as working fluid.

In order to reveal the flow and heat transfer mechanism in the air-conditioning evaporator,a steady distributed parameter model of an air-conditioning evaporator is established based on basic thermophysical laws,while R22 is the working fluid.

The distributed model of transmission line is applied and the effect of capacitance on it is precisely considered, its precision is hence greatly enhanced.
