Mathematical approach for determining the optimal size of a logistic unit in case of high transport risk.

There are various freights that are transported at increased risk under certain conditions. An example of such logistics is military supplies passing by air, water or land through the territory of the enemy. One approach to increasing the ability to reach delivery to its final destination is the dividing and transporting them into separate parts. Thus allows, in case when one part of the delivery is destroyed to be repeated only the destroyed one in order to obtain the full volume of the initial delivery for the intended purpose. The task, however, could be considered as ambivalent character: the bigger number of consignments to which delivery is divided increases security, but on the other hand increases costs significantly. The current article presents a mathematical approach that determines the effective level of division of delivery into separate transport units in regards of reaching the final intended destination. It has been proven that for a certain risk and size of delivery there is an optimal number of logistic transport units. [ABSTRACT FROM AUTHOR]
