Purpose

To be able to continuously provide affordable services to consumers, managers of critical infrastructure (CI) maintenance supply networks have to balance investments in resilience with costs. At the same time, CI providers need to consider factors that influence resilience such as the geographical spread or the location of the network. This study aims to contextualize supply chain resilience knowledge by exploring how maintenance resource configurations impact resilience and costs in CI supply networks.

Design/methodology/approach

An in-depth longitudinal single case study of a representative CI provider that has centralized its maintenance supply network is used. Data were collected before and after the change to evaluate the effect of the changes on the maintenance supply network.

Findings

This study shows that in this specific CI maintenance context, structural resource choices such as the quantity or location of spare parts and tools, the creation and exploitation of tacit knowledge and staff motivation impact both resilience and costs due to geographical spread, network location and other network properties.

Originality/value

This study extends general supply chain resilience knowledge to a new setting (i.e. CI) and shows how existing insights apply in this context. More specifically, it is shown that even in engineered supply networks there is a need to consider the effect of human agency on resilience as the creation and exploitation of tacit knowledge are of immense importance in managing the network. In addition, the relationship between normal accidents theory and high reliability theory (HRT) is revisited as findings indicate that HRT is also important after a disruption has taken place.

将弹性与关键基础设施维护供应网络联系起来

目的

为了能够持续向消费者提供负担得起的服务，关键基础设施 (CI) 维护供应网络的管理者必须平衡弹性投资与成本。同时，CI 提供商需要考虑影响弹性的因素，例如地理分布或网络位置。本研究旨在通过探索维护资源配置如何影响 CI 供应网络的弹性和成本，将供应链弹性知识背景化。

设计/方法/途径

使用了对已集中其维护供应网络的代表性 CI 提供商的深入纵向单个案例研究。收集变更前后的数据，以评估变更对维护供应网络的影响。

发现

本研究表明，在这种特定的 CI 维护环境中，结构性资源选择（例如备件和工具的数量或位置、隐性知识的创建和利用以及员工积极性）会因地理分布、网络位置和其他因素而影响弹性和成本。网络属性。

原创性/价值

本研究将一般供应链弹性知识扩展到新环境（即 CI），并展示了现有见解如何适用于这种情况。更具体地说，表明即使在工程供应网络中，也需要考虑人类能动性对弹性的影响，因为隐性知识的创造和利用在管理网络中非常重要。此外，重新审视正常事故理论与高可靠性理论 (HRT) 之间的关系，因为研究结果表明 HRT 在发生中断后也很重要。
