Considering synthetically the stochastic factors like processing time,arrival rate and due date of the job,combination performance of dispatching rules and routing rules was analyzed under different breakdown rates by simulation and the most optimized combination of dispatching rules and routing rules were given under each performance measure.

The article introduces flood forecast plan, flood control criterion, dispatching rule, system structure and function, boundary design of the dispatch system of the Longtouqiao reservoir.

This paper proposes Colored Petri Net-based modeling method according to the automatic material handling systems of the tobacco trade cigarette-packing product workshop, and designs an effective expert system of optimized-dispatching rules of AGVS, to increase the product efficiency of the material handling.

Modeling of priority scheduling rules;

A combination decision model of scheduling rules based on simulation is presented for multi-objective problems of job shop scheduling.

The algorithm combines the merits of scheduling rules and the tabu search algorithm,uses the scheduling rules to construct good initial solutions,speeds up the tabu search algorithm\'s convergence rate,and also reduces the entire algorithm\'s operations,and enables the algorithm to have better project utility.
