 The network extension theory and its applications for analysis of circuits are introduced. Developed just in recent years, the theory deals chiefly with the properties of networks when some changes in their construction take place, providing a new approach for circuit analysis. The approach is efficient especially for the treatment of modifications and connections of networks and for the generation of symbolic network functions of large scale networks. Some practical techniques are discussed in detail.... The network extension theory and its applications for analysis of circuits are introduced.

Network analysis is a method for studying interactions between the elementsin a system and how to make the system attain optimum performance fromthe overall point of view. Same as system analysis, network analysis has tosolve modeling and optimization problems. In recent papers discussing network theory and its applications, manyauthors concern themselves with computer algorithms. Obviously computers havebecome useful tools in network analysis. Considering the fact that graphicalcharacteristics of various network systems are almost the same, the author suggests the use of display units, which should allow manmachine interaction, tomake network analysis more effective. The author aims at offering a more effective tool for solving various problems in this field. Taking shortest path,which is one of the most basic problems in graph theory, as a numericalexample, the author develops a program for use with display units and uses itsuccessfully on PRC Type 751 display unit operating with PRC Type DJS6computer. This piece of research work appears to be a meaningful attempt atexploring new areas of application for display units. This piece of researchwork also appears to have laid some groundwork for using network analysis tosolve problems such as: maximal flow, minimum cost flow, critical path method, program evaluation and review technique, decision analysis, interpretivestructural modeling, etc. This paper begins with briefly explaining the storage of graphs in a computer, network calculations, and the algorithm of Dijkstra for the shortest pathproblem. Next the numerical results for G={15, 34} obtained from RumanianType Felix C256 computer are presented. Then this paper dwells on explaining the essentials of and steps for the analysis of the shortest path with PRCType 751 display unit. Since full advantage is taken of the rapidity of computer calculation anddisplay in the case of computer graphics, the user will very likely find thispaper's method intuitive and convenient. The piece of research presented inthis paper further indicates that computer graphics with manmachine interaction feasible can be applied to a wide range of problems.  近年来在讨论网络图论的一些专著中,很多都涉及到了计算机算法问题[1][2][3],显然,计算机已成为网络分析的一种有效工具。考虑到各种网络系统的图形特征是基本相同的,因此作者提出了用人机交互功能较强的光笔图象仪系统辅助分析的设想,目的是为解决该领域中不同类型的问题提供更为有效的工具。作者通过图论中最基本的问题之一——最短路问题计算的实例,编制了图象仪系统的应用软件,并在国产计算机DJS6和751图象仪系统上联机调试成功,从而为探索图象仪应用的新领域作了有益的尝试,并为今后解决诸如最大流问题(Maximal Flow)、最小费用流问题(MinCost Flow)、关键路径法(Critical Path Method)、计划评审技术(Program Evaluation and Review Technique)、决策分析(DecisionAnalysis)、结构模型解析(Interpretive Structural Modeling)等问题打下了基础。   << 更多相关文摘
