摘要

本文所研究比較的模擬策略包括事件導向、活動導向、過程導向和三階法四種策略。本主首先對每一種策略的基本概念和運算法則做文獻上的整理和說明，然後再依據效率性、易讀性、易寫性、表達能力和內聚力、耦合力這五個層面有系統地去此較這四種模擬策略的特性。本主之主要創見在以軟體工程上對良好程式品質所要求的高內聚力、低耦合力兩個特性，比較不同模擬策略之間的差異，任何一個模擬策略只能在時間、條件或實體三者之一符合高內聚合力、低耦合力的要求。

並列摘要

Four simulation strategies including Event Scheduling, Activity Scanning Process Interaction and Three-Phase Approach are studied in this paper. First, this paper makes a literature survey of each strategy's concepts and algorithm, and then makes systematic comparisions in the aspects of Efficiency, Readability, Writeability, Expressive Power, Cohesion and Coupling. The main contribution of this paper is to find a new way to explain the difference among these four strategies from the standing points of High Cohesion and Low Coupling, two mostly desired criteria for a good quality of program modules. With the three possibilities of time, condition and object, each strategy can only satisfy both high cohesion and low coupling from one of them, but fails in the other two.
