Oilfields must increase their production due to the current price of oil barrels. The sale these oilfields by big companies enabled new enter exploration and segment brownfields gas through subsea intervention projects. However, projects require specific product development that involves technical requirements engineering department analyze. This research aims apply SWARA-MOORA-3NAG multicriter...

In the construction industry, materials that are used for producing concrete and their mixture proportions an important decision-making optimization problem manufacturers. Amounts (mixture proportions) of materials, which in order to obtain a high strength functional concrete, can positively or negatively affect performance criteria individually determined each customer. Furthermore, effect sig...

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...

This paper investigates the selection of best suitable eco-friendly organic and in-organic refrigerants for heating, ventilation, air conditioning (HVAC) renewable energy devices. Inorganic are used to cool devices, such as solar cells, photovoltaics, electronic Owing community’s importance, development in this area has rapidly improved over past few years. R134a, R404, R717 have become most HV...

Abstract: Education is one of the most important aspects in world. continues to change and develop an orderly logical manner. The world education cannot be separated from role a teacher. teacher process teaching learning activities classroom shape character students. Therefore, expected able create human resources who have knowledge abilities. Based on this, selection best teachers needs done s...

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...
