Scheduling Problem Of Several Studies

Scheduling problem is a fruitful area of research that has profound practical background and broad application prospects. Its research on the social and economic development played an invaluable role.And with more profound sense; we can say that, to solve the scheduling problem has a great meaning for the promotion of our economic development now.To solve the fixed job scheduling problem is to solve many problems with limited resources and production scheduling, such as industrial production in the processing of the workpiece priority issues, port unloading of vessels, loading problem, even the location of the bus station car parking arrangements is allocated to the hair line occupancy problems. To solve this problem can speed up the development of China's current pace of market economy.In the classical scheduling problems, the machine can be usually assumed that it can work all the time without failure. But in practical, it may not. Therefore, it's more meaningful to consider the failure in the scheduling problem of the machineIn this paper, it will talk about the topics scheduling of random failure; Pieces with degradation is the sorting problems; the classical machine scheduling problem; Scheduling problem of network flow model, and so on. Through the adoption and comparison of the single machine scheduling problem we can see that there is no solution for the multi-server solution to server problems so far, so the purpose of this paper is to find a kind of approach that can handle or analysis the server failure and to use this method. The expected results after the handled data is treated as a machine which can be seen as a twice failure in the normal operation of the server, so we can continue to use the network flow model, or to maximize profits for its discussion. And we will the server and queuing system of customer classification and obey the law into the scheduling problem.
