“…This 58 assumption is supported: For example, Hewlett-Packard totally re- 59 placed DeskJet 500 printers with DeskJet 510 printers (Lim & Tang,60 2006); Microsoft stops selling older software versions as soon as a new 61 version is released; Google stopped selling Nexus 4 when launching 62 Nexus 5 in September 2013, and so on. Consequently, the assump- 63 tion of a complete replacement strategy is widely used in the liter-64 ature (e.g., Arslan, Kachani, & Shmatov, 2009;Carrillo, 2005;Cohen, 65 Eliashberg, & Ho, 1996& Ho, , 2000. 66 We consider a firm that adopts a complete replacement strategy to 67 introduce multiple generations of a product at regular time intervals 68 within a given planning horizon.…”
