In this paper we present an economic model for analyzing enterprise IT service downtime cost, first on a standalone basis and then in a supply chain setting. With a baseline probability model of Poisson arrival frequency with random downtime duration, we analyze optimal production of a firm’s investments in reducing frequency and duration of downtime, and corresponding premiums for insuring against downtime cost. We also present a model for the spillover effect of downtime for interconnected firms in a supply chain, and discuss how third-party insurance coverage can help enterprises to internalize the externalities of spillover effects on the supply chain.

企业IT服务停机成本和供应链中的风险转移

在本文中，我们提出了一种经济模型，用于分析企业IT服务的停机成本，首先是在独立基础上，然后是在供应链环境中。使用具有随机停机时间的Poisson到达频率的基线概率模型，我们分析了企业在减少停机频率和停机时间方面的最佳投资生产，以及相应的保费以确保停机成本。我们还为供应链中相互联系的公司提供了停机时间的溢出效应的模型，并讨论了第三方保险如何帮助企业内部化供应链溢出效应的外部性。
