Quantifying the Bullwhip Effect in a Simple Supply Chain: The Impact of Forecasting, Lead Times, and Information
Chen, Frank; Drezner, Zvi; Ryan, Jennifer K.; … - In: Management Science 46 (2000) 3, pp. 436-443
An important observation in supply chain management, known as the bullwhip effect, suggests that demand variability increases as one moves up a supply chain. In this paper we quantify this effect for simple, two-stage supply chains consisting of a single retailer and a single manufacturer. Our...

Returns and the bullwhip effect
Chatfield, Dean C.; Pritchard, Alan M. - In: Transportation Research Part E: Logistics and … 49 (2013) 1, pp. 159-175
An almost universal assumption in the bullwhip effect modeling literature is that excess goods may be returned without restriction. We seek to determine if returns impact the level of bullwhip effect observed in a multi-stage supply chain. We build a hybrid agent/discrete-event simulation model...

Last time buy and repair decisions for spare parts
Behfard, S.; van der Heijden, M.C.; Al Hanbali, A.; … - In: European Journal of Operational Research 244 (2015) 2, pp. 498-510
Original Equipment Manufacturers (OEM's) of advanced capital goods often offer service contracts for system support to their customers, for which spare parts are needed. Due to technological changes, suppliers of spare parts may stop production at some point in time. As a reaction to that...

Supply chain scheduling at the manufacturer to minimize inventory holding and delivery costs
Selvarajah, Esaignani; Zhang, Rui - In: International Journal of Production Economics 147 (2014) PA, pp. 117-124
In a supply chain, a manufacturer receives jobs from suppliers at distinct time points, and produces and delivers final products to customers in batches. The manufacturer can be modeled as a single machine in the supply chain and the problem can thus be modelled as minimizing the sum of weighted...
