Designing optimal structure of road construction machines kits

Abstract

The article presents modernized mathematical model for optimizing the structure of road sets of machines, taking into account the technical and organizational downtimes of mechanization facilities employed in technological construction processes. In the process of operation, technical downtimes are caused by the wear of parts, assemblies and units of transport and technological machines, the removal of which takes more time each year. This circumstance causes an adequate decrease in the annual output of the mechanization facilities. The organizational kind of downtimes is caused by internal and external factors. The internal factors lead to the under-exploitation of the potential capabilities of individual pieces of the equipment of the kit. External factors are characterized by late supply of construction materials, caused by the irregularity of their production and delivery. Dependencies between productivity and the operating period of transport-technological machines, obtained using this mathematical model, will allow determining the real time of work, the output of machines, taking into account their age.
