最近,最大乘积模糊关系不等式被应用于描述无线通信站系统。然而,当发射基站和信号测试点之间出现任意线路故障时,经典的最大乘积系统不再有效。针对无线通信基站系统中的任意线路故障,引入并研究了任意项缺失(ATA)最大乘积模糊关系不等式。为了减少由来自基站的电磁辐射引起的损害,通常期望最小的解决方案。然而,ATA最大积模糊关系不等式的解集结构表明,在大多数情况下,最小解是不唯一的。因此,我们进一步引入了字典序,并定义了字典序最小解的相关概念。字典序最小解实际上是一个最优调度,它按字典序最小化电磁辐射。本文提出了一个多项式复杂度的有效算法,用于求ATA最大积系统的唯一字典序最小解。最后,我们提出的分辨率算法与现有的一个比较,并通过一个数值例子说明。
Recently the max-product fuzzy relation inequalities were applied to describe the wireless communication station system. However, when an arbitrary line fault appears between the emission basic station and the signal testing point, the classical max-product system is no longer effective. Considering an arbitrary line fault in the wireless communication station system, we introduce and investigate the so-called arbitrary-term-absent (ATA) max-product fuzzy relation inequalities in this paper. In order to reduce the damage caused by the electromagnetic radiation from the basic stations, a minimal solution is usually desired. However, the structure of solution set to the ATA max-product fuzzy relation inequalities shows that the minimal solutions are not unique in most cases. Hence, we further introduce the lexicographic order and define the relevant concept of lexicographic minimal solution. A lexicographic minimal solution is indeed an optimal scheduling, minimizing the electromagnetic radiations in a lexicographic order. An efficient algorithm with polynomial complexity is developed for obtaining the unique lexicographic minimal solution of the ATA max-product system. At last, our proposed resolution algorithm is compared to the existing one and illustrated by a numerical example.
