Vulnerability of production systems with multi-supplier network: a case study

摘要

Despite management capability and innovative production techniques, uncer- tainty and variability that affect production systems cannot be completely controlled or eliminated. Thus, it is important to evaluate the intrinsic system characteristics that are susceptible to the negative impact of unexpected or un- avoidable disruptions on system performance. In this paper, we apply the concept of vulnerability to production systems in order to provide some insight into the effect of uncerainty and variability on system performance. In particular, a model of a production system with a multi-supply network that is subject to process uncertainty and product mix variability is used to analyse the effects of system vulnerability.
