Data models for service failure prediction in supply-chain networks
This addresses service reliability issues for supply-chain operators, but it is incremental as it applies existing methods to a specific domain.
The paper tackled predicting and explaining service failures in last-mile supply-chain networks by analyzing 500,000 services using Random Forests and Association Rules, achieving an average sensitivity and specificity of 0.7 for five failure types.
We aim to predict and explain service failures in supply-chain networks, more precisely among last-mile pickup and delivery services to customers. We analyze a dataset of 500,000 services using (1) supervised classification with Random Forests, and (2) Association Rules. Our classifier reaches an average sensitivity of 0.7 and an average specificity of 0.7 for the 5 studied types of failure. Association Rules reassert the importance of confirmation calls to prevent failures due to customers not at home, show the importance of the time window size, slack time, and geographical location of the customer for the other failure types, and highlight the effect of the retailer company on several failure types. To reduce the occurrence of service failures, our data models could be coupled to optimizers, or used to define counter-measures to be taken by human dispatchers.
