Study on Double ETV Task Scheduling of Airport Cargo Terminal Based on Expert System

摘要

Double ETV (Elevating Transfer Vehicle) task scheduling of airport cargo terminal involves task priority, in-out warehouse task ratio, equally distributing task, ETV mutual avoidance, double containers task and other problems. Task scheduling is very complex and the task scheduling method has strongly affects on efficiency of ETV. To solve this problem,, the paper builds up the knowledge base of expert system by summarizing double ETV task scheduling problems. Then the relative inference engine is formed in accordance with the features of the knowledge base and double ETV task scheduling characteristics of airport cargo terminal. Finally, a simple example is realized by computer simulation. It is proved the feasibility of applying expert system in double ETV task scheduling of airport cargo terminal.
