We present in this paper a real world application for the elicitation of decision parameters used in the evaluation of thermal comfort in high speed trains. The model representing the thermal comfort is a hierarchical one and we propose to use different aggregation methods for different levels of the model. The methods used are rule-based aggregation, Electre Tri and 2-additive Choquet. We show...

The influence of dyeing and spinning on the characteristics of cotton fibers and its impact on the properties of cotton mélange yarn has been investigated. Grey cotton fibers with mean fiber length and fineness of 29 mm and 4.2 micronair were pre-treated and dyed. Three ring yarns were spun from 100 % grey cotton (R.R.Y), 50-50 % blend of dyed and grey cotton (M.R.Y) and 100 % dyed cotton fiber...

Concrete with gangue which made with ordinary Portland cement at different water binder ratio (0.35, 0.40 and 0.45) or ordinary Portland cement at water binder ratio of 0.35 incorporating 10% fly ash or 20% fly ash; 20% fly ash and 1% early strength agent, slag with the replacement of 15% or 30%, or 15% fly ash and 15% slag were made and exposed to a wetting–drying sulfate environment. The comp...

Based on grey language multi-attribute group decision making, a kernel and grey scale scoring function is put forward according to the definition of grey language and the meaning of the kernel and grey scale. The function introduces grey scale into the decision-making method to avoid information distortion. This method is applied to the grey language hesitant fuzzy group decision making, and th...

Imagining, thinking, producing, developing and changing what you produce are among the main traits that make human beings human. Human question their raison d’être, life, quality of lives; in other words, they ask why how. All these inquiries result production information, a flow information produced, sometimes product. Today, world where takes place at an unprecedented pace, one needs to posse...
