斐氏網路 (Petri nets) 可以做為系統分析的工具 【1,6】，以表示、瞭解及分析一系統的結構、流程及狀態。但由於缺少邏輯閘門 (logicgates)，斐氏網路對如電路系統、管理資訊系統等則無法進行完整的描述或系統分析【1，3，4】。本論文則擴大斐氏網路使其包含邏輯閘門，即亦以斐氏網路來表示邏輯閘門，此擴大後之斐氏網路則能做為系統分析之工具。
本論文的第一章中介紹斐氏網路，第二章中討論如何將各種邏輯閘門表示為斐氏網路形式，第三章中研究此含有邏輯閘門的斐氏網路其狀態方程式的型式，第四章則以應用於真空抽氣系統的例子做為說明，第五章是為本論文的結論。

The Petri nets have been used in system analysis for describing, understanding and analyzing the structure, procedures and states of a system. Lacking the logic gates, systems such as electronic circuit system, management information system(M.I.S.) are unabled to be completely described or analyzed by Petri nets.
In this thesis, the Petri nets are extended to contain logic gates. That is, logic gates are represented by Petri nets. The extended Petri nets can be used as a tool for system analysis.
Chapter 1 in this thesis briefly introduces Petri nets. Chapter 2 discusses the ways to represent kinds of logic gates by Petri nets. In chapter 3, the state equation of this logic-gates-containing Petri net is studied. Chapter 4 applied this extended Petri net to vacuum pumping system. Chapter 5 is the conclusion.
