“…Several studies used numerical simulation for investigating the impact of modular design on costs (Ben-Arieh, Easton, & Choubey, 2009;Bhandare & Allada, 2009) or on sales revenues (Kang, Hong, & Huh, 2012). A few case studies have developed approaches for modular designs and tried these out in real companies (Cao, Luo, Kwong, & Tang, 2014;Hauser, 2001;Krishnan, Singh, & Tirupati, 1999;Luo, Kwong, Tang, Deng, & Gong, 2011;Moore, Louviere, & Verma, 1999;Muffatto, 1999).…”
