Purpose – The production dice game is a powerful learning exercise focusing on the impact of variability and dependency on throughput and work‐in‐process inventory of flow lines. This paper seeks to extend the basic dice game along the following lines. First, it will allow operations to...

An important supply chain research problem is the bullwhip effect: demand fluctuations increase as one moves up the supply chain from retailer to manufacturer. It has been recognized that demand forecasting and ordering policies are two of the key causes of the bullwhip effect. In this paper we...

Supply chain collaboration creates a gain (a surplus) compared to uncoordinated or disconnected supply chain policies. In this paper we review policies to allocate the “gain” to supply chain members so that each firm’s objective becomes aligned with the supply chain’s objective. In other...

Capital assets, such as manufacturing equipment, require maintenance to remain functioning. Maintenance can be performed when a component breaks down and needs replacement (i.e., corrective maintenance), or the maintenance and part replacement can be performed preventively. Preventive...

In this paper, we describe a link between Markovian binary trees (MBT) and tree-like quasi-birth-and-death processes (TLQBD) by associating a specific TLQBD to each MBT. The algorithms to compute the matrices Gk in the TLQBD then correspond to the algorithms calculating the extinction...

In this paper we introduce the adaptive MMAP[K] arrival process and analyze the adaptive MMAP[K]/PH[K]/1 queue. In such a queueing system, customers of K different types with Markovian inter-arrival times and possibly correlated customer types, are fed to a single server queue that makes use of...
