Abstract
The paper presents a novel approach to solve problem of stairs shape assessment for two-story individual dwelling houses. Selection among available shapes and construction of stairs is a multi-criteria decision-making problem in nature. It depends on a set of different conflicting criteria, that have different optimisation direction, different measurement units. There is determined the set of the main criteria to assess the alternatives is as follows: Stairwell Area, The Total Area of Climbing, “Climbing Lane” Area, The Cost of Stairs, and Ergonomics. A novel original hybrid MCDM (multi-criteria decision-making) model, which based on ten different multi-criteria decision-making methods: Game Theory, AHP, and SAW, Multiplicative Exponential Weighting, TOPSIS, and EDAS, ARAS, Full Multiplicative form, Laplace Rule, and Bayes Rule, is presented.
Highlights
Construction activity is one of the most resource consuming sectors in EU
High consumption of natural sources, high amount production of industrial wastes and environmental pollution are some of the factors, which have a major impact on the environment and is a major consumer of a wide range of naturally occurring and synthesized resources
There does not exist a single solution for a multi-criteria decision-making problem that simultaneously optimizes each criterion
Summary
Everybody knows that on the one hand, human behaviour and wellbeing is influenced by building’s architecture It has a big interaction with the building forms and their organization on the land area. On the other hand, building’ characteristics have a major impact on the environmental and energy performance of buildings. Few of research papers present studies about stairs design in public buildings. Several of research papers deals with stairs in singlefamily houses They examines the problems related to medicine (impact on human movement apparatus) (Peng et al 2016) and aging (Huang et al 2014; Alcock et al 2015). In the study choice of the stairs geometric parameters should be related to multi-criteria such as aesthetics, surface area, climbing convenience, and construction technology
