Truck drayage is essential to link locations and logistics nodes in the port and hinterland. In the Port of Hamburg, for example, about 90% of inter-terminal transports are handled by truck and severely contribute to the road traffic volumes, carbon emissions and situation at gates. An intelligent and automated optimization of truck drayage operations can be the basis for a more efficient appointment booking and facilitates an eco-efficient utilization of trucking capacities, as well as for coordinating available truckers based on real-time information and the use of mobile trucker apps.

Previous research and a prototype called port-IO encouraged and impulsed the collaboration with EUROGATE Intermodal (EGIM), a leading drayage and intermodal transport provider in the Port of Hamburg (Germany), to develop an innovative decision support system for providing timely port-related truck operations. Besides developing efficient solution methods for solving rich vehicle routing problems, the dispatching system considered trailer swaps, truck appointment scheduling and multi-objective optimizations for covering emission-related objectives.

The practical project paved the way for the start-up driveMybox, which was founded in mid 2019. The cloud-based digital platform fully organizes containerized truck transports by establishing fully digital processes and by using AI at its core.

Since January 2020, container transports are fully managed by the platform, from the booking over the planning, optimization and execution to automated settlement. The platform is the first of its kind in the container logistics industry and transformed mainly paper-based processes into fully digital, transparent and optimized processes, where mathematical optimization, (meta-)heuristics and predictive analytics are used to further improve planing and operations. After a seven month beta phase and the final go-live in August 2020 (DVZ, 2020), the company transported thousands of containers and generated a multi-million turnover for 2021 (Hafen Hamburg, 2021). This year, new offices were opened in Milan (Italy) and Rotterdam to drive the expansion of the platform in Europe.

Libra is the European platform for the activation and exchange of electricity reserves. The platform is used to select reserve offers for activation on replacement reserve (RR) and manual frequency restoration reserve markets (mFRR). At the center of the platform, an optimization algorithm is used to optimize the set of bids to activate in order to satisfy demands, maximize social welfare and compute the market clearing price while abiding by numerous market rules and taking into account many complex dimensions such as market coupling, time coupling, complex offers, etc.

Because of the criticality of the process, the market clearing algorithm has a very short time to run and must return a solution in all circumstances. Therefore, the optimization system must achieve very high performance and robustness.

After an introduction to the platform and its purpose, we will discuss the approach used to tackle this problem in practice and ensure meeting the performance and resilience goals.

This seminar presents ongoing work on a joint project to develop a multimodal schedule-based routing application. This application is motivated by the necessity of transport policymakers to evaluate the potential impact of public transport investments at the national and European levels. In the first part of the seminar, we illustrate accessibility metrics that permit to evaluate the performance of a public transport system by combining the spatial distribution of the population of the region of interest with the average travel time between any pair of possible origin-destinations within that region. In the second part of the talk, we present Veloci-RAPTOR, the algorithm at the core of our multimodal schedule-based routing application that solves an all-pairs constrained path problem. We conclude with a perspective on ongoing activities.

The Geospatial Planning & Budgeting Platform is being developed by researchers and practitioners from Analytics for a Better World Institute in close collaboration with World Bank.

These digital decision-support interfaces focus on promoting inclusive and resilient access to social and economic infrastructure services, including for health. The Geospatial Planning and Budgeting Platform (GPBP) provides users with online, interactive, and collaboration-friendly interfaces for powerful descriptive and prescriptive decision support. The GPBP user interfaces for any given problem statements (or “use-cases”) are presented in two forms:

(i) an interactive website for non-technical end-users,

(ii) a Jupyter Notebook environment that allows for exploratory and background analytics and visualization to be made more transparent and accessible.

In this talk, the overview of two GPBP use cases – Health Facility Location Optimisation in Timor Leste and Stroke Case Accessibility Optimization in Vietnam – will be explained. The challenges and opportunities of this platform along with potential extensions and the plans for the way forward will also be discussed.

In this talk, I will make a comparison between call centers and hospitals, from the point of view of operations management.

I will show how advanced prediction and optimization techniques impact call center operations and how academia and industry interact to move the field forward. We will compare this with the current state of our health care system, identify similarities and differences, and discuss what blocks further improvements in quality and efficiency.

About the speaker:

Ger Koole is full professor of business analytics and optimization at Vrije Universiteit Amsterdam. He is also founder and lead scientist of the call center workforce management company CCmath. He obtained his PhD at Leiden University in 1992 with theoretical work on the control of queueing systems.

Before moving to Amsterdam he held the postdoc positions at CWI and INRIA. Over the years, his interests moved to applications of optimization under uncertainty, especially in call centers, health care and revenue management.

Dr Jason Atkin is a member of the Computational Optimisation and Learning lab in the School of Computer Science at the University of Nottingham. He has been working with NATS and Heathrow airport since he started his PhD on the topic in late 2003. Although he has also worked on various other airport optimisation and modelling problems, his work has primarily been focusing on real-world runway sequencing at the airport, considering the ‘often messy’ real world constraints and characteristics of the problems. Having previously been a software engineer in industry, he applied various software engineering techniques to the challenge, which gives a somewhat different perspective to the usual academic approaches.

This talk will discuss the work with NATS and Heathrow, which contributed to Heathrow being able to predict take-off times accurately enough to gaining CDM compliance. Various versions of the problem will be discussed, introducing both the real world situation at Heathrow and considering the various academic simplifications that have sometimes been used for similar problems, and their implications in the real world. Ongoing work with Heathrow is still providing further enhancements and improvements over time.

In the face of the climate emergency, several measures are being taken to move to more sustainable sources of energy. The transport sector has increasingly adopted Electric Vehicles (EVs) in order to cut down on greenhouse gas emissions. This has led to the necessity of accounting for these technologies in the area of field services delivery. In particular BT Research have been developing technical solutions to support the introduction of EV into their large fleet operations. This led to new models to plan for new EV chargers deployment minimising the energy risk, and then to schedule jobs and charge activities of electric vehicles in the feasible operational manner for field engineers while minimising the productivity impact.

By optimising the infrastructure, the required investment can be determined as well as minimising the disruption to the operations caused by the rollout of the new VE fleet and infrastructure can be minimised. As usual in operational research applied to decision-making support, the measuring of the impact on real-case trials is key to make sure changes adoption is going smoothly.

When trying to solve puzzles, practitioners train themselves on OR techniques (and other techniques). Puzzles are good ways for large and small companies to have OR practitioners from academia and consulting take a look at their specific issues (ROADEF / Euro challenges). Puzzles can support challenging students to show motivation and skills.

Why puzzles are very interesting with regards to equivalent computational challenges? We need to map real world concepts to mathematical concepts and that’s useful! They also tell a story, so they’re very easy to share and explain.

Kaggle challenges are part of the buzz around data science. During the presentation, I’ll mention other public challenges with examples: The IBM Ponder this challenge, the Decision Management challenge, and, not to forget, the “Comité International des Jeux Mathématiques”, and I will request the audience’s feedback with regard to deciding if challenges are good training paths for OR consulting and, also, if real-world business OR helps practitioners get better at challenge

Traditional last-mile delivery planning purely based on optimization methods often lacks important real-life aspects and thus does not satisfy relevant operational requirements. Only experienced couriers have tacit knowledge about the delivery area and its customers, forcing them to deviate from planned routes. They know where to find good parking spots, when to best approach certain business customers, and which neighbors to approach at what times when the actual recipient is not at home. This tacit knowledge is almost impossible to collect and maintain, let alone to incorporate in optimization algorithms.

Thus, we at Deutsche Post DHL developed an algorithm following a different approach: We aim at implicitly learning about this tacit knowledge from historical tours and combine this with optimization algorithms to plan routes that an experienced courier would choose. In this talk we will present details of our algorithm, which incorporates machine learning, statistics, and optimization in a novel way. Furthermore, we show how it impacted last-mile delivery planning at Deutsche Post after its rollout across Germany.

Embedding OR functionalities in operational tools to address a large class of problems requires designing the software architecture to provide the required modularity.

In this talk we will present comparative design of component primitives (Nodes Arcs Boxes) in Python and Julia. A particular exploration question is how to use Julia for the design of object oriented software.
