Role of Data in Solving Capacity and Efficiency Problems in Real-time Logistics

In the world of real-time Logistics, every minute counts. It shows up not just as customer experience (SLA-Compliance & NPS), but also as the overall ability to accept N orders (Capacity) and deliver them in optimal time using minimum resources (efficiency). Such systems need to react fast to on-ground changes such as traffic, weather, availability of delivery-executives and their proximity to demand areas, availability of shipment at the source (in Swiggy’s case, prepared food at restaurants) etc. Both, real-time and historical data play a significant role in choosing “what” to optimize for and “how”. In this talk we discuss some of these challenges at Swiggy, the nature of historical and real-time data, and our journey of using these inputs in designing optimal solutions for Capacity (when exactly should we stop accepting orders) and Efficiency (orders/delivery-executive/unit-time). We also discuss challenges with data accuracy, high-variance and the necessary trade-offs in designing an optimial system.
