Speaker: Alex Tschan, Project Manager, ALDI SE & Co. KG Murr
ALDI SÜD Germany launched the ‘Data-Driven Special Buys’ project in response to pandemic-related supply chain disruptions, market shifts, and increasing competition. This initiative combines advanced analytics and operations research with employee engagement to optimize product lifecycles. Ensuring practical relevance and applicability in business, including the satisfaction of all stakeholders involved (stores, national buying, project management, German board), was a high priority.
Methods used include: (1) multi-period optimization models (MIPs) for product allocation optimization, considering product demand and stock-keeping costs; (2) machine learning classification methods for store product allocation (“SAM”); (3) a proprietary algorithm (“ANA”) for just-in-time reallocations between stores; (4) a multi-period dynamic programming model (“DAVE”) for nationwide inventory control; (5) a sophisticated version of DAVE (“DAVE SDP”); (6) multivariate regression analyses for budget allocations of small product quantities for stores; and (7) a smartphone application (“Market-Whispering”) to engage 50,000 employees in product selection.
The project faced coordination challenges and required a strategic shift from decentralized to centralized inventory control. Proprietary software for the special buys product range improved operational efficiency, impacting the daily operations of 40,000 employees, and led to annual savings of several million euros in Germany.

Speaker: Ryan O’Neil, CTO and Co-Founder of Nextmv
More and more, data science and decision science practitioners are seeking to combine machine learning forecasts with actionable and optimized decisions. This can include anything from predicting traffic patterns for delivery scheduling to consumer buying behavior for inventory management. But bridging these two disciplines can be challenging.
In the on-demand logistics space, these worlds are colliding more frequently with practitioners generating demand forecasts that feed into shift scheduling models that feed into vehicle routing models. Getting to an 80% good solution for the optimization side is not hard. What is hard is the remaining 20% where people tend to over-optimize their models using fixed inputs (which makes the model more brittle in the face of uncertainty). What if, instead, we could take those 80% solutions and use horizontal compute to scale them up in the face of uncertainty?
In this talk, we will explore what has made blending ML and OR outputs challenging, the roles of deterministic and stochastic optimization in relation to ML, and how scenario testing techniques via horizontal computing provide an expedient and more accessible path for combining these worlds.
Ryan O’Neil is CTO and cofounder of Nextmv (nextmv.io). Previously, he led the Decision Engineering department at Grubhub and Zoomer, which owned forecasting, scheduling, routing, and simulation. Ryan worked as an Operations Research Analyst at MITRE, and led software teams at The Washington Post, Yhat, and Polimetrix. During this, he earned a PhD in Operations Research at George Mason University, and wrote his dissertation on real time routing for pickup and delivery problems.

The presentation discusses optimization solutions for strategic financial decision-making and enterprise-wide risk management in financial institutions. The software is a sophisticated prescriptive analytics solution based on a stochastic dynamic optimization approach and solves highly complex real-world financial planning problems under uncertainty. The application is an integrated platform for banking, insurance, pension funds, wealth management and multinational financial groups.
The software computes dynamic, multi-period financial strategies with concrete action plans that fulfill diverse management goals, priorities and regulatory requirements. The strategies help institutions to prepare simultaneously for multiple economic and financial market scenarios in uncertain operating environments. The computed forward-looking strategies lead to considerable improvements in performance when compared with more traditional approaches. This improvement in performance becomes particularly noticeable in exceptionally difficult and turbulent operating environments.

Demand response programs play a key role in the energy transition, offering potential benefits to multiple players: grid operators (alleviating congestion in networks), retailers (enabling to manage wholesale buying and retail selling prices) and consumers (reducing the energy bill without jeopardizing comfort). This work presents a modular set of mixed-integer linear programming models of appliance operation aimed at being incorporated in autonomous Home Energy Management Systems allowing for the integrated optimization of all energy resources. The models consider different cost objective function components (energy and power costs, monetized discomfort) as well as dealing with the user’s discomfort derived from operating appliances out of the habitual periods, settings, and temperature ranges. The models are developed in a building block manner to be used with different objectives of economic and comfort nature.
