Abstract
Supply chain disruptions pose significant risks to production systems. Unfortunately, the number of publications that study the real-life impacts of supply chain disruptions on production systems is extremely small, and the question of how these disruptions affect production systems has not been fully investigated. This research seeks to fill this gap using assembly-line data from a vehicle manufacturer in China. With these data, the authors estimated econometric models to assess the impacts of minor disruptions on production using two different metrics: daily output in terms of number of vehicles manufactured, and the disruption duration in minutes. Time-dependent effects were also considered to assess the extent to which the effects of disruptions on daily output and disruption duration change over time. The resulting models were analysed to identify which disruption factors are the most impactful in terms of daily output and disruption duration.
