提出了网络压缩的算法。该算法适用于所有肯定型和非肯定型网络的压缩。在压缩过程中充分考虑了非关键工序的总时差使网络压缩的费用尽量减小。在考虑了建筑施工过程中运用知识的方法后,本文设计实现了反向推理机,并根据建筑施工中许多因素的不确定性设计了相应的不确定推理程序。本文对网络资源均衡优化方法作了改进,用一种启发式的方法进行资源均衡优化,较好的解决了以往用线性规划解这类问题时所遇到的对计算机内存要求很高的问题。最后,给出了利用CPICS对宝钢3号高炉热风炉系统进行跟踪控制的实际情况。 Proposed a network compression algorithm. The algorithm is suitable for all positive and non-positive network compression. In the compression process to fully consider the non-critical processes of the total time difference so that the network to reduce the cost of compression. After considering the method of using knowledge in the process of building construction, this paper designs and realizes the reverse reasoning machine, and designs the corresponding uncertain reasoning procedure according to the uncertainty of many factors in the construction. This paper improves the method of network resource balance optimization, and uses a heuristic method to optimize resource balance, which solves the problem of high memory requirement for computers in the past with linear programming. Finally, the actual situation of using CPICS to track and control the blast furnace system of No.3 blast furnace in Baosteel is given.
