物资调运系统中模糊条件的量化及其网络解法

<正> 在湖南邵阳市“工业企业集团规划”研究中,我们看到,化工企业的化肥调运是经常的、大量的、牵涉的数据、报表和计算是非常多的。过去,这些工作一直靠人工来处理,并常常靠决策者的主观经验办事,缺乏科学依据。因此,工作效率低、出错率高。如何实现物资调运和管理决策的的科

A Study on the Algorithms of Interpretive Structural Modeling

This paper discusses some aspects of the algorithms in the interpretive structural modeling process. First, it clarifies the mistake and paradox existed in a previous algorithm. Based upon the above analysis, the paper presents a new algorithm named as algorithm 1, by which the identification of cycle subsets can be made without the level partition. Then a theorem about cycle subsets and its corollary are proofed and the other algorithm named as algorithm 2 is put forward, which has many advantages to identify cycle subsets. The example shows that complexity in ISM can be reduced greatly by utilizing the proposed algorithms. Finally, some useful conclusions are reached.
