“…Dominguez et al (2019) state that investing in technologies to process product returns helps managers to absorb the uncertainty in terms of quality and reduce the bullwhip effect. Recent technological innovations, such as radio-frequency identification (RFID), distributed systems and cloud computing have been investigated as to whether they can reduce information distortion through data acquisition, data analytics, and real-time communication systems (Lindner et al 2010;Zhigang 2012;Gowda and Subramanya 2017).…”

Closed-loop supply chains are complex systems as they involve the seamless backward and forward flow of products and information. With the advent of e-commerce and online shopping, there has been a growing interest in product returns and the associated impact on inventory variance and the bullwhip effect. In this paper, a novel four-echelon closed-loop supply chain model is presented, where base-stock replenishment policies are modelled by means of a proportional controller. A stochastic state-space model is implemented, initially to capture the supply chain dynamics while the model is analysed under stationarity conditions with the aid of a covariance matrix. This allows the bullwhip effect to be expressed as a function of replenishment policies and product return rates. Next, an optimisation method is introduced to study the impact of the Internet of Things on inventory variance and the bullwhip effect. The results show that the Internet of Things can reduce costs associated with inventory fluctuations and eliminate the bullwhip effect in closed-loop supply chains.
