No-centralize Newsvendor Model with Re-distributed Decision-making Power

In this paper, we study a no-centralize newsvendor model with re-distributed decision-making power. It is different from classical model that sale process is distinguished normal sale and promotion stages. Vendor own to the right of promotion policy selected to management promotion action for increasing their return when real demand is lacking. We get two mathematical expressions of traditional optimization order quantity q* and new optimization market size N*. At the some degree, we also discuss the sensitivity of (q*,N*) as some parameter changes.
