Decision support system in management of concrete demolition waste
Concrete waste stream can be measured by the amount of waste produced per unit of time, i.e. the efficiency of demolition works. To model the average value of concrete waste stream ( Φ o , m 3 / h , the labour intensity of demolition works is used: (1.4) Φ o = W e = 1 N c , where W e is the operating efficiency of the works, m 3 /h, which is determined from the working time standard [h/m 3 ]) .
