Study of the Optimal Designing System in Resources Development Projects

资源开发项目规划需要对资金、材料、人力、条件等进行优化。本研究工作开发了一个支持项目规划的专家系统，该专家系统不仅具有依赖于知识库的推理机制，而且能够并行执行从属程序，以保证推理的正确性。其附属程序包括各种随机处理、模型模拟、数据库搜索和专家系统中的子系统等，其处理时间比常规推理过程的计算时间长得多，这些子程序在计算操作中负荷很大，并在联网的另多台计算机上同时执行，该系统是由一台局域网连接的个人计算机在DOS操作系统下构成的，因此可以以较低的成本实现。专家系统、知识调节方法、模糊理论和神经网络的模拟方法、软件语言和网络，等进行了评价和讨论。已成功地开发了一个用于解耦处理的通信系统和一个解耦处理型专家系统。

The optimization is needed for capitals, materials, human abilities and terms in planning a resources development project. In this research work an expert system has been developed to support the planning of the project.The expert system is not only having a reasoning mechanism depending on the knowledge base but also is able to parallel execute subordinate programs in order to make sure the reasoning. The subordinate programs include a various kinds of stochastic treatments, simulations by models, data base searches and subsystems in the expert system, etc. It takes a much longer treatment time in the execution than the calculation time in a conventional reasoning process.These subprograms are heavily loaded in the calculating operation and are simultaneously executed in another multiple computers connected in a network, whilst the demanded results are returned to the main program.The system is possible to be realized relatively cheaply because it is constructed by a LAN-connected personal computer working with the operation system of DOS.Expert systems, knowledge regulation methods, simulation methods using the fuzzy theory and neural networks, software languages and networks, etc.have been evaluated and discussed in this research work. A communication system to be realized for a decoupled treatment and a decoupled treatment type expert system have been successfully developed.
