  • Improvement of the algorithm for automated formation of solutions for the production of construction works based

    The work is aimed at improving the algorithm of automated formation of solutions for the production of construction works based on the combinatorial approach. The essence of the approach is to form all feasible solutions for the production of construction works, taking into account the specified resources and constraints, and choosing the best option according to the specified criteria. At the same time, at some stages of the generation of altenatives, it is advisable to eliminate obviously losing options, in particular, it is proposed to take into account the losses from downtime of workers and construction machines formed due to some difference in the total productivity of workers and construction machines when forming the composition of resources for performing mechanized construction work. The proposed algorithm assumes the choice of the composition of resources for performing a mechanized technological process with minimal losses from idle resources.

    Keywords: organizational and technological design, simulation model, algorithm, logical and mathematical model, combinatorial approach, multivariate design, automated control system in construction

  • Methodology of determination routes for transportation dangerous goods.

    The article is devoted to study proposals for determination of transportation of dangerous goods. Methodology of selection of the most optimal route for transportation dangerous goods is presented and consists of 11 steps, and also includes factors influencing movement goods throughout the roads. The methods allow to decrease subjectivity factors of assessments of transportation risk and, thereby, to reduce probability of choosing a wrong way to move dangerous goods.

    Keywords: transportation of dangerouse goods, methodology of movement goods throughout roads, safety, factors of safety moving by roads.
