Abstract

Service supply chains make our economy and daily lives possible. These supply chains span many industries, including transportation, computing, telecommunications, healthcare, defense, construction, agriculture, building, factory equipment, and more. The complexity of these supply chains is staggering, with each consisting of hundreds or thousands of intricately interconnected locations with inventory investments ranging from $200M-$2B for major equipment manufacturers and operators. When equipment requires service, the service parts are needed within minutes/hours of the failure, an impossible feat made possible through advanced technology. Servigistics, the leading service supply chain optimization solution, helps ensure service parts are available in the right place, quantity, and price. With sophisticated algorithms and advanced data science, Servigistics recommends what parts to buy, repair, and move around the supply chain, tuned to maximize equipment availability and readiness. These data science methodologies include statistics, machine learning, and operations research. Servigistics is a pioneer of industrial AI enabling autonomous optimization of complex service supply chains involving millions of decisions every day without user intervention. This talk describes the mission of AI-driven autonomous planning, explains how Servigistics is at the cutting edge of innovation, offers an overview of data science applications used, and explains the success factors and challenges in Industrial AI.
