高可用度运行是关键设备系统运营企业产生收益的根本保障。为了减小因小概率突发故障造成的严重收益损失以及可能地继发资金流风险，既要设计合理的服务合同增强对服务供应商的激励，又要同时考虑收益损失减缓策略。基于性能合同（PBC）是根据服务结果给予补偿的新兴激励合同，而购买营业中断保险（BI）是减缓关键设备故障继发资金流风险的有效策略。本文以委托-代理理论为建模框架，研究BI保险与PBC合同集成设计模型，探讨购买保险与否两种情景下的PBC合同最优设计和供应商的最优服务能力决策，分析BI保险决策对PBC合同设计方案的影响规律，调查运营商购买BI保险的决策条件。该成果是维修服务运作与金融保险领域跨界研究的首次尝试，其理论分析结果有助于为关键设备运营企业跨部门决策提供指导。

Maintaining a high level of system availability is the fundamental gurantee of the profitability of firms operating mission-critical equipment in an environment characterized by low-frequency, high-impact events such as equipment failures. Once an operational disruption occurs, the firm hardly affords significant operational downtime and often causes financial distress. To mitigate the severe impact of the unexpected disruptions, a proper incentive mechanism has to be in place so that the service supplier would commit the necessary capacity for recovery. Meanwhile, the financial distress risk can be mitigated by transferring the financial liability away to a third party insurer. Performance-based contracting (PBC) is an emerging incentive mechanism where the supplier receives compensation based on realized availability. Business interruption insurance (BI) can protect against the potentially financial risk for the firms. In the paper, the principal-agent contracting models are proposed for an outsourcing setting in which the firm cannot write the supplier's service capacity decision directly into the contract but instead must incentivize the supplier using the PBC and where the firm makes decision on purchasing the BI to eliminate the downtime loss and transfer financial distress. The service performance of the PBC between the firm and the supplier is measured by not only the cumulative downtime but also the individual service experience. The PBC contract design model is presented firstly as the benchmark, in which the firm has to choose the optimal pair of contract terms consisting of the fixed payment and the penalty rate to maximize profit composing the expected production profit of the equipment uptime, the payment to the supplier, production downtime loss, financial distress loss and the goodwill loss, while the supplier chooses optimal service capacity to maximize his utility composing the payment from the firm and the capacity cost. Secondly, the PBC contract model with the BI is proposed, where the insurance premium term is added and the downtime loss and financial distress loss are eliminated in the firm's objective function. Finally, it is explored how the BI impacts on the optimal PBC contract terms and whether the BI need be purchased. The major insights from our analysis are followed: (1) the frequency of disruptions is an important factor in determining contract terms and the supplier's capacity investment decision. (2) The BI and the performance incentive of the PBC contract are partly substitutable. (3) The BI can reduce the sensibility of which the frequency of disruptions influences on the the supplier's capacity, contract terms and the firm's profit. The study is a first attempt on the understanding of the interplay between operation and insurance in the maintenance service of the mission-critical equipment. The theoretical results contribute to the decision-making of the operation-finance interface in the firm operating mission-critical equipment.
