Based on analysis of Pawlak’s rough set model in the view of single equivalence relation and the theory of fuzzy set, associated with multi-granulation rough set models proposed by Qian, two types of new rough set models are constructed, which are multi-granulation fuzzy rough sets. It follows the research on the properties of the lower and upper approximations of the new multi-granulation fuzz...

The subject of the study was hardware implementations of fuzzy controllers as CMOS analog devices on the base of implementation of fuzzy inference rules as multi-valued logic functions using summing amplifiers as building blocks. Earlier a functional completeness of summing amplifier with saturation in an arbitrary-valued logic was proven that gave a theoretical background for analog implementa...

This research was conducted because of complaints from several parents at Elementary School regarding recipients the Poor Student Assistance (PSA) who were still less objective. XY regularly conduct screening activities every year to select prospective PSA recipients. selection is made so that this assistance are students entitled it. Some should be accepted as a committee but do not mistake ch...

Abstract. In this article, a study on multi-objective optimization of the milling process is presented. CNC machine, cutting tool as TiAlN, experimental material SCM400 steel and coolant Caltex Aquatex 3180 oil have been used in experiment. The objective to simultaneously ensure minimum surface roughness maximum removal rate (MRR). Taguchi method has applied design an matrix with five input par...

an orthogonal approach to the fuzzification of both multisets and hybridsets is presented. in particular, we introduce $l$-multi-fuzzy and$l$-fuzzy hybrid sets, which are general enough and in spirit with thebasic concepts of fuzzy set theory. in addition, we study the properties ofthese structures. also, the usefulness of these structures is examined inthe framework of mechanical multiset proc...

In recent years, hesitant fuzzy sets and neutrosophic sets have aroused the interest of researchers and have been widely applied to multi-criteria decisionmaking problems. The operations of multi-valued neutrosophic sets are introduced and a comparison method is developed based on related research of hesitant fuzzy sets and intuitionistic fuzzy sets in this paper. Furthermore, some multi-valued...

In a high-tech society, the main factor of economic development are activities related to research and (R&D). The purpose paper is rank all 27 countries European Union (EU) according selected indicators innovation potential. author singled out five relevant from Eurostat database (section innovation) in assessment conditions for EU using MOORA (Multi-Objective Optimization on basis Ratio An...

HLP (hub location problem) tries to find locations of hub facilities and assignment of nodes to extended facilities. Hubs are facilities to collect, arrange, and distribute commodities in telecommunication networks, cargo delivery systems, etc. Hubs are very crucial and their inaccessibility impresses on network whole levels. In this paper, first, total reliability of the network is defined bas...
