Adapting Forecasting Algorithms to Accommodate Disruptions

In many industries supply chain disruptions have always been a part of business and recent tumultuous times emphasized the importance of the right way of handling them. Frequently occurring minor disruptions are often ignored in operational planning, likely because these are not expected to cause serious issues as long as they are not widespread. Most modern Machine Learning methods can indeed mitigate the risk caused by randomly spread minor data anomalies. However, even the best forecasting models are susceptible to invalid data points caused by large and persistent supply chain disruptions. We present a forecasting approach combining Machine Learning and traditional timeseries based techniques. This flexible approach ornamented with outlier detection and lost sales estimation allows us to build forecasting systems that are robust against supply chain disruptions. Machine Learning provides the ability to estimate the impact of various causal factors from a holistic viewpoint, while traditional methods ensure the lower-level characteristics are not lost in the process. Moreover, these systems provide critical input needed in making pricing, promotional and markdown decisions.
