Object -Oriented Simulation Approach for AGV Systems

AGV 시스템에 대한 객체지향 시뮬레이션

This paper presents an object -oriented simulation approach. AgvTalk, to design and analze AGV system configuration and control. Smalltalk-80 is used as an implementation language in AgvTalk. AgvTalk includes 25 object classes and more than 300 object methods in its library. Compared to general purpose simulation languages. AgvTalk provides several important benefits. First, the hierarchical features and modularity create possibilities for the extension and reuse of simulation object components. This extensibility and reusability provide more flexible modeling capabilities for simulation of many alternative AGV systems. Second, detailed behavior of each object in the AGV system can be modeled easily and exactly in AgvTalk because there are no limiting modeling constructs. Third, AgvTalk provides a user -friendly simulation modeling environment through the MVC -triad of Smalltalk-80.
