Utility Function Applied in Cost Optimization of Oil Gas Pipeline Integrity Maintenance;

Spotbeam handover scheme for LEO satellite mobile communication systems by using utility function;

Worst-Case Index based on Utility Function;

First, a new kind of effective function is proposed, by which the decision making matrix with different dimensions and different kinds of indexes is changed uniformly into effective matrix.

In order to get the synthetical estimate value of ship-to-air battle channels,we use three effect functions to calculate the value of index of the project-layer.

The paper uses linear and exponential function as the effect function of transporters to analyze,and to compare the ex- pected effects of three strategies(checking,seizing and fining)of managing exceeing limit and overload transportation in the transporters with different preferences and shows an example.

When the effectiveness function is obtained through conjoint analysis, the forecast of product sales can be made to determine the best combination of product features.

In this paper, the set pair analysis is applied to build effectiveness function for multiple objective decision-making.

First,an index system of C4ISR is founded in the paper;Second,through the hierarchical configuration uses AHP in order to get power of the index;Third,uses effectiveness function to get effectiveness value and uses integration evaluation model to get effectiveness value;Finally,a practical example is given to confirm the method.
