“…Few researchers in the discipline of industrial engineering have applied classical thermodynamics reasoning to analyzing management systems. For example, the thermodynamic entropy concept has been applied to analyzing decision trees (Drechsler, 1968), manpower systems (Tyler, 1989), logistics management (Whewell, 1997), business process management (Chen, 1999), product life cycle (Tseng, 2004), inventory management (Jaber, Nuwayhid, & Rosen, 2004, price-quality relationship (Nuwayhid, Jaber, Rosen, & Sassine, 2006), and coordinating orders in a supply chain . This paper incorporates the concept of entropy cost developed in Jaber et al (2004) into the EOQ problem with permissible delay in payments, i.e., into the model of Goyal (1985).…”
