Supply contracts are designed to minimize inventory costs or to hedge against undesirable events (e.g., shortages) in the face of demand or supply uncertainty. In particular, replenishment terms stipulated by supply contracts need to be optimized with respect to overall costs, profits, service levels, etc. In this paper, we shall be primarily interested in minimizing an inventory cost function ...

Recent papers have shown that, in contrast to ―the Long Tail‖ theory, movie sales remain concentrated in a small number of hits. These papers have argued that concentrated sales can be explained, in part, by heterogeneity in quality and increasing returns from social effects. Our research analyzes an additional explanation: how incomplete information may skew sales patterns. We use the movie br...

Micro, Small and Medium Enterprises (MSMEs) have an important role in economic development order to achieve thq quality of growth. Intense competition among MSMEs requires a good inventory control that can help them minimize costs maximize profits. One the often experiences problems is Sabun Bening Official. To solve Official, Holt-Winter Exponential Additive forecasting method used as guide pr...

The complexity of managing a category assortment has grown tremendously in recent years due to the increased product turn-over and proliferation rates in most categories. It is an increasingly di±cult task for managers to ̄nd an e®ective assortment due to uncertain consumer preferences and the exponential number of possible assortments. This paper presents an empirically-based modeling framewor...

For the (S − 1, S) lost sales inventory model with several demand classes that have different lost sale penalty cost, three accurate and efficient heuristic algorithms are presented that, at a given base stock level, aim to find optimal values for the critical levels, i.e., values that minimize inventory holding and penalty cost.

Online retailers have maintained a price advantage over brick-and-mortar retailers since they were not required to collect sales tax. Recently, several states have required that the online retailer Amazon collect sales tax during checkout. Using transaction-level data, we document that households living in these states reduce Amazon purchases by 8% after sales taxes were implemented, implying a...

Abstract We consider a single-item production–inventory system under base stock policy for inventory control. model the as closed Gordon–Newell network. The population size of network is equal to level, which sum finished goods and work-in-process inventory. Each exogenous demand, follows Poisson process, releases production order new unit increases amount When there are no items in available, ...
