Agv ( automated guided vehicle ) optimization is a typical np problem, in the course of initial group generation, this article applied accumulator process, crossover operator based continuous insertion heuristic mode, and push - connect - exclude method. according to stacker running process and characteristics, stacker optimization was devided into two parts, the first one was shelves number optimization, the second one was travel scheduling problem. finally, this article written genetic algorithm program based on c
Agv的優化調度屬于典型的np問題，在初始群體的產生中，採用聚加過程，並建立了可行插入的條件；提出了基於連續插入啟發式的交叉運算元；採用了推?銜接?排除過程來使任務的滿意度達到最佳；針對堆垛機的運行過程，建立了數學模型，並依據其運行特點，把堆垛機的優化分為兩部分，一是針對庫位號的優化，改變傳統的庫位號排列方式，利用遺傳演算法建立起比較合理的庫位號排列順序；二是把堆垛機的運行線路簡化為旅行商問題，並做了適當的修改。The control strategy of hoist system of stacker crane is studied. through reliability analysing of control system of hoist, comparison of running and fork movement system, the weakness of controlling methodology of hoist system is found and then creates the improving model and the proposal of controlling system of hoist, in which use ac vvvf speed regulation instead of variable speed regulation, so as to get the stacker crane with better orientation precision and running speed
通過對堆垛機的提升控制系統進行可靠性分析，對比行駛和伸叉控制系統，找出提升控制系統中控制方法最薄弱的環節，建立了提升控制系統的改進模型，提出了提升控制系統的改進方案，對堆垛機的升降電機控制採用交流變頻調速方法，代替原系統中提升電機的變級調速控制，以使堆垛機在升降時獲得更高的定位精度和運行速度。
