Impact of Dynamic Characteristics of Supply Chain on Own-account Fleet Size in the Optimal Transport Sourcing Mix

Abstract In this paper, we explored the impact of time demand characteristics in supply chain on role of own-account fleet in the optimal transport sourcing mix. For that purpose, we used the multiple regression analysis to evaluate the simulation and optimization results, and the historical database of a real trade company. The regression analysis reveals that the certain indicators of demand variability and uncertainty directly impact on the optimal number of vehicles in own-account fleet. Further, the intercept in regression equation for the dependent variable number of own-account vehicles can be expressed as the function of daily demands and fleet characteristics.
