Multi-constrained Packing Optimization Model Of Research And System Development

The thesis is based on automatic loading system .At first it introduces the traditional performance in this field,then it has designed a new scheme with studing practical loading operation. The scheme is a three-step optimizing algorithm,its purposes are loading capacity optimization and efficiency of.operationg.With the practical loading restriction, it integrates heuristic algorithms and genetic algorithms, adopts layer loading idea and space partition and combining rule.The Optimizing algorithm is composed of combination pretreatment,bottom space optimize and up space optimize.It can satisfy the loading restriction and has practicability.At first,the thesis introduces the research background and the research actual state.Secondly, it analyzes the character of combinatorial optimization,and introduces the principles and processes of heuristic algorithms and genetic algorithms.Thirdly,it has built the optimization model. According to the model ,it designes Optimizing algorithm,and put forward three-step Optimizing algorithm. then introduces the algorithm flow chart in detail.At last,it designes the automatic loading system based on the three-step optimizing strategy.The system has perfect function,it can provide dispatch guidance and loadong guidance.it has practicability and is worth of spreading.
