In addition,by the mechanics of introducing Lagrange mutiplicity and mean-value theory,we prove the existence of constraint optimal policies, moreover prove that the constraint optimal policies may be markovian or the convex conbination of two markovian policies.

Based on the concepts and features associated with security object in DaMeng ORDBMS,the policy of labelling objects and filtering objects in MAC is presented,and the constraints policy of filtering objects is discussed emphatically.

Study on mine fire comprehensive prevention of genetic algorithms optimal strategy;

Realization of optimal strategy for power system low-frequency and low-voltage load reduction;

Aim at the countermeasure between missiles and targets in space,the space simulation model based on differential games for SAM was established and its optimal strategy of resistance was deduced Moreover the adaptive critic neural networks arithmetic method was presented and used to calculated the simulation model.

In this paper we discuss the optimal problem on a discrete-time,single item, periodic review inventory system with yield and demand uncertainty, the main objective is to analyze how the uncertainty of yield rate and demand affect the optimal policy and cost in the system.

By using the dynamic programming method the optimal policy is obtained.

Revise the value coefficient of linear programming about production plan problem whose optimum solution had been obtained,and build mathematical model of cost minimization,give optimal policy that total revene increase the fixed value under the condition of unchangeable optimum base of original linear programming.
