Abstract:

Purpose.Economical implementation of competitive strengths of haul trucks by the generalization of scientific thoughts, tenets and principles forming a high level of competitiveness of the trucks.

Methodology. Results are received through the application of several methods: critical analysis and systematization were used in order to determine the notion of competitiveness and indexes of quality evaluation; ABC-analysis and mathematical statistics were exploited in order to rank the indexes of competitive strength evaluation depending on technical characteristics of a vehicle; economical and mathematical modeling were applied in order to determine the expenditures concerning the transportation of rocks; finally, the method of network modeling assisted to the optimization of staffing and interrelated projects.

Findings.Special aspects regarding competitive strengths of the haul trucks which are designated for exploitation in open-pit mines were revealed. This identifies technical characteristics of the trucks which are adjusted to special conditions and rules of roach transportation according to the requirements of mining enterprises.

It is demonstrated that practicality concerning the substitution of certain haul truck models and means of developing their competitive strengths should be determined according to the integrated index of competitiveness which is supposed to be calculated as a ratio between group economical indexes and group technical indexes. The economical index is substantiated regarding the positive and negative influence of automobile technical options on its singular economical indexes.

Unit costs of establishing new technological work conditions in an open-pit mine connected with putting new models of haul trucks into operation were set up. Direct expenses are taken into account as well as indirect fuel consumption required for open-pit work connected with haul trucks being put into service. The structure of the innovative project based on certain types of work is offered which can be independently performed either by an enterprise, business coalition or outsourcing principles. The structure of innovative activity management was developed owing to innovative department is being added to the automobile factory.

Originality. Is embodied in the development of the concepts concerning economical evaluation of competitiveness of haul trucks and methods for improving competitive strengths of haul trucks which are bond with innovations.

Practical value.Methods for improving competitive strengths of haul trucks concerning their exploitation in the conditions of open-pit mine are identified. Additionally, research and methodology tools of innovative project implementation to improve haul trucks are substantiated.
