First , three kinds of analytical methods including netting theory , compound theory and nonlinear fem were performed to obtain the stresses and deformations of srmcs 首先,采用网格理论、复合理论和非线性有限元方法对发动机壳体的应力和变形情况进行分析与计算。
The principal research results and contents are composed by two interdependent parts , namely , the petri net theory part and the supervisory control part , where the latter is based on the former 本论文主要内容是由petri网理论和监控理论两大部分有机组成的,其中后者以前者为基础。
This paper studies the application of petri net theory in marketing and mainly focuses on systematically model construction and analysis concerning the problems occurred during marketing procession 本文研究petri网理论在市场营销中的应用,主要针对市场营销方面的问题进行系统建模和分析。
The basic principle of petri net theory and queue theory can be found in this dissertation . then , we analyze the disadvantage of the combination of wavelength - and spatial - division multiplexing technique 介绍了petrinet理论和排队论的原理,并分析了传统空分/波分光纤光栅传感复用技术的不足。
The research work of this paper not only provides reliable theoretical and technological basis for the following research work on the marketing field , but also enlarge the room for the application of petri net theory 本论文的研究工作不仅为我们今后在市场营销领域中的研究工作提供了可靠的理论、技术依据,而且也开辟了petri网理论应用研究的新天地。
Second , the developing of the petri net theory is introduced , and the theory of the petri net , the theory of color petri net is introduced . lay the foundation for the establishment of the machine shop based on petri net 其次,分析了petri网理论的发展历程,介绍了petri网的基本理论和赋色petri网理论,为进一步建立机加工车间的petri网模型打下基础。
The establishment of cpn model proves the reliable data transfer service which based on the mces in petri nets theory for the first time , the simulation model ’ s design and validate is a helpful reference for our later task to validate the protocol in theory 因此本文的模型实现起来简单易理解。仿真模型的建立从网论的角度验证了服务元系统构架下的可靠传输服务,并为从理论角度论证协议的正确性提供了较好的参考。
The performance of tcp networks and its relative problems are important researching subjects . this dissertation presents our outcomes of performance analysis of the operation mechanism of tcp networks based on petri nets theory . in the meanwhile , we further study the performance of interworking unit between tcp / ip lans and atm trunk Tcp网络的性能及其相关问题是目前计算机网络研究的重要方面,我们从全面、深入的分析tcp网络的运行机制出发,抓住tcp网络既随机又相关的特点,提出了新的分析观点,采用了petri网作为建模求解工具,揭示了tcp网络的实质。
The paper not only used the sequence diagrams to descript the cooperation of pda and server in communications , but only adopt petri net , a kind of fdt , to built four different models on protocol ' s dynamic actions . we proposed the constrict expressions : 1 . finding out and fixing the errors , we validated the protocol with petri net theories 在通用的时序图描述通信协议动态交互的基础上,用一种形式化描述技术? ? petri网抽象通信协议的动态行为规范为一种链路层半双工停止-等待协议,从简单到复杂建立4个不同侧重点的petri网模型,分别描述通信协议的不同动态行为:交互,超时,出错处理。
