HIGHLIGHTS
- Statistical analysis was used to estimate the operational parameters of the vehicles.
- A multi-criteria method of selecting a fleet of vehicles for the tasks was developed.
- Reliability and cost of use evaluate the selection of a fleet for the tasks.
- A new decision model for selecting a fleet of vehicles for the tasks was presented.

ABSTRACT
The article presents a method of selecting a fleet of vehicles with a homogeneous structure
for tasks based on the statistical characteristics of their operational parameters. The selection of a vehicle fleet for tasks is one of the stages of vehicle fleet management in transport
companies. The selection of a vehicle fleet for tasks has been defined as the allocation of a
vehicle model to a given company, which is associated with the unification of the vehicle
fleet to one specific type. The problem of selecting a fleet of vehicles has been presented in
a multi-criteria approach. The operational parameters assessing the selection of vehicles for
the tasks are mileage and the number of days to the first and subsequent failure, and vehicle
maintenance costs. The developed method of selecting a fleet of vehicles for the tasks consists of two stages. In the first stage, the average operating parameter values are determined
using statistical inference. In the second stage, using the MAJA method, a unified model of
the fleet of vehicles operating in the enterprise is established.
