Analysis of the appropriate model of the system of technological motor transport

Abstract

Open-pit truck technical operation is an essential component of the industrial transport operation. The organization level of the system of maintenance and repair of technological automotive transport specify the effectiveness of mined bulk transportation and play a role of vehicles long-term service condition. The optimal organization of maintenance and repair is probable in case of system analysis providing, technological automotive transport system development, algorithm and technique of control of scheduled actions on every vehicle. The analysis of current models showed the number of shortcomings from which designed a complex mathematical model of technological automotive transport maintenance and repair system is free that determine position and state of every open-pit truck in space of loss of function, maintenance and recovery, permit a description of vehicles operation considering technological and resourceful states of equipment, state transitions there between, at the same time finding a way of minimization of industrial transport service costs. Before the design of an optimal control algorithm and technique of its implementation, the verification of complex mathematical model adequacy and its availability in the real world has required. The parametric identification of the model is carried out during which the convergence of specified values of technological automotive transport system parameters with values calculated by statistical and numerical methods was obtained. It arrived at the conclusion that adequacy model of technological automotive transport system technical operation was produced which can be used for its functioning optimization.

The calculated optimal controlling actions in terms of the degree of scheduled actions of maintenance and repair on the open-pit trucks and level of transitions from preventive maintenance states to operation state allow developing an algorithm and technique for dynamic adjustment of parameters of maintenance and repair of every open-pit truck that will become the reliable basis for adaptive open-pit truck operation system design.
