This paper presents a new model for determining vehicle routes that
takes into account the parameters of the environment, health, use of
space and logistics operating costs. The advantage of the TSDSM can
be seen in its potential for designing routes for the EFV and EUF vehicles
of logistics operators in urban zones. The model takes into account the
real state of the fleets of logistics operators and the fact that they have
a limited number of EFVs. TSDSMis based on the integration of the modified
WLC method and the modified Dijkstra algorithm within the
framework of a GIS. In the first phase of the TSDSM using the modified
WLC method and GIS, the parameters and criteria that affect the vehicle
routes are processed. In the TSDSM four parameters are identified (the
environment, health, use of space and logistics operating costs) that
are broken down into a total of 21 criteria. The weight coefficients of
the parameters/criteria are obtained by surveying experts who have a
minimum of ten years' experience of managing transport processes. A
final map of the benefits of the transport network is obtained as a result
of the first phase. In the second phase the routes of the EFV and EUF
vehicles are determined using the modified Dijkstra algorithm. The traditional
Dijkstra algorithm does not provide the opportunity for simultaneously
making the routes for EFV and EUF vehicles, which is why in
this research the traditional Dijkstra algorithm was modified.
