Based on the fuzzy analysis in government purchase and bidding,a new weigh vector has been defined with knowledge of fuzzy synthetic evaluation and superiority chart.

The method is very efficient to the system with multiple levels and index,use superiority chart to decide the importance of each factor.

This Paper briefly introduces the decision of multiple inPut weighted Precedence chart and Fibonacci's optimum:method of determining the optimum blasting Parameter for the striP mining Project according to author's research.

Precedence Chart is a math-statistics analysis method, which is used for analyzing the importance of each factor to the target by matrixes chart, and offering basis for management decision-making.

guidance time,distance to enemy fighters,energy,adaptive degree to object type and adaptive degree to object maneuver,then studies priority order,and at last establishes math model of guidance law decision based on optimum order method.

This paper establishes missiles attacking efficiency evaluation system of vessels formation, then describes a new method of missiles attacking efficiency evaluation of vessels formation—optimum order method, which is simple to determine the nature and quantification, at last an instance is presented.

Precedence order method was used in optimum selection for sewage treatment works, Analysis showed that the method possessed sample operation, reasonable results and good practicality.

An application of order method in software quality assessment;

Based on the analysis of order method,this paper proposes new method to the air attack target threat-order method of multi-objective decision problem,for in command of automation under the condition of modern war of judgment,make policy to provide the new basis.

The new order method which adopts the rank of sequential statistics to determine the value of prior-order is adopted to rank and classify service contact.
