Management model for the construction`s waste use in walls manufacturing

Abstract

The mathematical model, which could be represented as a fuzzy inference tree for project man-agement aimed at waste usage in wall manufacturing, is proposed in the article. The factors classification that affect production`s environmental and economic efficiency is presented. The proposed ecological and economic efficiency criterion and influence factors are lin- guistic variables consisting of fuzzy terms on the corresponding universal sets. The proposed hierarchical system of math- ematical models allows the intelligent choice of proper building material, depending on the influence of environmental para- meters, socio-economic parameters, and engineering and technological parameters of a building object, based on fuzzy log- ical expressions “IF-THEN”. The proposed model could be used as a support system model in the decision-making process at the early feasibility stage. Estimating pros and cons based on the results of a virtual experiment in terms of proposed cri- terion value for specific construction waste allows proper planning of construction waste usage in the construction sector. The proposed model can be used as a design and engineering tool in the decision-making process for forecasting the eco- logical and economic efficiency of the use of waste in the manufacture of walls.
