Global economic competition has spurred the manufacturing sector to improve and invest in modern equipment to satisfy the needs of the market. In particular, machine tool selection is the most important problem; it plays a primary role in the improvement of productivity and flexibility in the manufacturing environment and involves the imprecise, vague and uncertain information. This paper prese...

Nondestructive evaluation of the prevailing compressive residual stress in the shallow subsurface layer of surface-treated metals is greatly complicated by the accompanying surface roughness and cold work. A high-precision laser-ultrasonic technique has been developed to study the feasibility of SAW dispersion spectroscopy for residual stress assessment on surface-treated metals in a wide frequ...

Generally, in real world multiple criteria decision making (MCDM) problems, we concern with inaccurate data. This paper transforms a fuzzy (FMCDM) problem into two linear programming models based on simple additive weighting method (SAW). The new calculate scores for each alternative optimistic and pessimistic viewpoints. To rank the alternatives, numerical value of arithmetic mean good score b...

Surface Acoustic Wave (SAW) devices, using interdigital electrodes, play a key role in today’s telecommunication systems and are widely used as electronic filters, resonators, delay lines, convolvers or wireless identification systems (ID tags). During the last three decades, demands set by the expansion of the telecommunication industry and many applications in sensor have resulted in the intr...

In the paper is presented Neuro-Fuzzy System as a decision-making support in selection of construction machines (the example selecting loader provided). Construction characteristics make basis for selection, but also other elements importance. The data modeling are prepared using Multi-Criteria Decision Making (MCDM) methods: Logarithm Methodology Additive Weights (LMAW), VIKOR, TOPSIS, MOORA a...
