Over the years, supply chain reconfiguration decisions have been solely based on operational risk. Simplification strategies, such as horizontal mergers, and networking strategies, such as risk pooling, are conflicting paradigms that have been shown to improve financial performance of supply partners. The implication of this to disruption risk is not fully known, especially as it concerns information security breach (ISB). Analysts have rated ISB as a huge disruption risk, costing businesses millions of dollars. Using a credible and well-established agent-based simulation approach and statistical analysis, we examine the impact of ISB on the simplification and risk pooling strategies respectively under three different order replenishment systems. The effect of reconfiguring the supply chain is first examined in a non-security breach scenario and then in a breached scenario. We find that reconfiguration has no benefit to a supply chain using a parameter based replenishment policy (option I), in both breach and non-breach situations, but leads to significant advantage when batch ordering model (option II) or a combined batch-and-parameter based ordering policy (option III) is used. We also established that batch ordering system favours the risk pooling strategy whereas a combined batch-and-parameter ordering system favours the simplification counterpart especially when the simplification is at the wholesaler tier. This study has significant implications for supply chain design as well as information security priorities. This is one of the first papers to look at how ISB impacts supply chain configuration and the role of ordering decision context.

供应链重新设计对信息中断影响的影响

多年来，供应链重新配置决策完全基于运营风险。横向合并等简化策略和风险分担等网络策略是相互冲突的范式，已被证明可以提高供应合作伙伴的财务绩效。这对中断风险的影响尚不完全清楚，尤其是当它涉及信息安全漏洞 (ISB) 时。分析师将 ISB 评为巨大的破坏风险，使企业损失数百万美元。使用可靠且完善的基于代理的模拟方法和统计分析，我们分别检查了 ISB 对三种不同订单补货系统下的简化和风险分担策略的影响。首先在非安全漏洞场景中检查重新配置供应链的效果，然后在漏洞场景中检查。我们发现，在违约和非违约情况下，重新配置对使用基于参数的补货策略（选项 I）的供应链没有好处，但在批量订购模型（选项 II）或组合批量和非违约情况下会带来显着优势。使用基于参数的排序策略（选项 III）。我们还确定批量订购系统有利于风险分担策略，而组合批量和参数订购系统有利于简化对应物，尤其是当简化在批发商层时。这项研究对供应链设计以及信息安全优先事项具有重要意义。
