Abstract:In the existing work in the literature, the addition-min fuzzy relation inequalities was applied to describe a peer-to-peer (P2P) network system. In such a model, the total download traffic of a terminal was considered. However, it is more reasonable to consider the largest download traffic in some cases. It is found that max-min fuzzy relation inequalities are more suitable for the P2P network system in such cases. The objective of this work is to reduce the network congestion under some fixed priority grade … Show more
“…As a consequence, the maximum solution of system (81) is x = (44,50,46,47,50,44). Therefore, we have (44,42,40,35,34,39). That is, the quality levels of T 1 , T 2 , • • • , T 6 are 35Mbps, 42Mbps, 40Mbps, 0Mbps, 0Mbps, 39Mbps, respectively.…”

“…To decrease network congestion, a minimal solution is usually required. Considering the fixed priority grade of all terminals in a P2P network system, Y. Ma et al [40] studied the lexicographic minimum solution to the corresponding maxmin FRIs. The authors proposed a detailed round-robin algorithm for computing the lexicographic minimum solution.…”
Resolution of the minimal solutions plays an important role in the research on fuzzy relation equations or inequality systems. Most of the existing works focused on the general minimal solutions or some specific minimal solutions that optimize particular objective functions. In a recently published work [43], the restricted minimal solution of fuzzy relation inequalities with addition-min composition was studied by M. Li et al. Motivated by the idea presented in [43], we investigate the so-called upper bounded minimal solution of fuzzy relation inequalities with max-min composition in this work.The upper bounded minimal solution is defined as the minimal solution that is no more than a given vector. Here, the given vector can be viewed as the upper bound. The major content in this work consists of two components: the existence and the resolution of the upper bounded minimal solution. First, we provide some necessary and sufficient conditions to determine whether the upper bounded minimal solution exists with respect to a given vector. Second, when it exists, we further develop two algorithms to search for the upper bounded minimal solution in a step-by-step approach. The validity of our proposed Algorithms I and II is formally proved in theory. The computational complexities of Algorithms I and II are O (mn) and O (mn 2 ), respectively. Moreover, our proposed algorithms are illustrated by some numerical examples.
