查询词典 total

The mathematical model by which the forming time can be precisely calculated is ratiocinated. This model shows that in SLS the scanning "delay" phenomenon can make the actual forming time greatly exceed the theoretical time, and the total number, total length of the scanning lines and the scanning speed have different effects on the scanning "delay".

A model is initially developed based on the in the integer programming, whose objective function is subject to the minimization of the total re-shuffle containers. To reduce the total number of reshuffles for retrieving the containers, a hybrid algorithm, which combines heuristic rule and distributed genetic algorithm, is employed to solve the model. The heuristic rule is to reduce the range of feasible solution and distributed genetic algorithm is to solve the optimization.
