Modelling the Impact of Cyber-Attacks on Web Based Sales

2019, Unpublished

Abstract

Performance Modelling to predict the quality of service (QoS) of computer systems and networks is widely applied. Similarly there is an abundant literature on the analysis and optimisation of supply chains and inventory control. This paper addresses some problems at the interface between these two areas, since computer systems and networks are widely used to control supply chains and E-Commerce systems. We develop an analytical modelling approach using queueing theory to study the impact of cyber-attacks on the economic performance of warehouse that sells perishable goods such as food that has a limited shelf life. We derive expressions to predict the loss of income that results from cyber-attacks on a web site used to order goods, and illustrate them with numerical examples.
