Modeling for Logistics System

The modeling methods available can not describe impacts of adjustment ability of logistics system on payoff and cost of logistics system. In view of such a fact, theorem of adjustment ability of logistics system in supply chain circumstance on condition that payoff of supply chain is a unique increasing process was proposed. A sequence of MGF (moment generating function) of out-of-goods risk process for logistics system is a martingale. The model we proposed can overcome shortcomings of previous ones which can´t describe characteristics of adjustment ability of logistics system. At last, Simulations results coincide with theoretical analysis.
