Operational Research is the science of better decision making. Aviation is a complex industry where existing and emerging threats need to be considered carefully when balancing the need for improved safety with the need to maximise passenger throughput, minimise the space taken up by security measures, and minimise unnecessary costs. How can we, as Operational Researchers, help the aviation industry to design ‘optimal’ security solutions?

The European gas infrastructure is being disruptively transformed into a future decarbonized energy system, a process that needs to be accelerated, given the current political and economic situation. On the one hand, there is a growing hydrogen market; thus, pipeline-based transport using the existing natural gas infrastructure becomes economically viable. Further, using existing infrastructure helps to increase public acceptance and accelerates the transition process. On the other hand, due to Russia’s aggressive invasion of Ukraine, gas supply and transportation have changed significantly in Europe and particularly in Germany by moving sources of supply from east to west in 2022.

In this talk, the maximum technically feasible feed-in of hydrogen into the existing German natural gas transport network is analyzed with respect to regulatory limits of gas quality. The basis is a transient tracking model that builds on the general pooling problem including linepack. We investigate the impact of the new supply situation on the hydrogen distribution by comparing historical gas flow data from 2020/21 to more recent data from 2022. It is shown that even with strict limits, the gas grid offers sufficient capacity to serve as a guaranteed customer for a large part of the green hydrogen generation capacity planned until 2030 for both periods. A higher hydrogen feed-in is possible in the current gas supply scenario, as the provided gas quality is higher, and existing and potential locations of hydrogen production are more likely to be found in the northwest of the network. With our presented method, it is possible to evaluate unexpected situations in the gas networks quickly and increase the system’s resilience.

Gary holds a PhD in systems thinking from Aston Business School and is a Fellow of the Operational Research Society.

Biodiversity loss and climate change continue to raise the stakes for environmental, agricultural and food policy across the globe. Issues in these policy areas can cascade across countries and across different sectors of the economy. The social-ecological systems within the policy remit of the UK Government’s Department for Environment, Food and Rural Affairs (Defra) often behave in ways that are complex and unpredictable. The policy challenges can be wicked and intractable, with potential solutions contested by actors with conflicting goals.

Systems thinking can help us understand complex issues by encouraging us to examine inter-relationships and account for wider factors, perspectives and influences within the problem-solving process. The Systems Research Programme at Defra has been running since 2019, providing a dedicated team to support Defra undertake systems thinking analysis to tackle some of its most complex and intractable issues. In this talk, I will introduce Defra’s approach to systems thinking analysis, highlight different techniques used and provide reflections on how systems thinking can be used to support policy and decision making in complex areas.

In this talk, we draw lessons from a leading automotive supplier who adapted its manufacturing scheduling approaches to leverage optimization to effectively schedule and synchronize its injection and paint lines. The supplier’s production model involves a combination of make-to-order and just-in-time to fulfill the needs of its automotive customers. Using optimization techniques has led to improved service level and capacity usage. The presentation will concentrate on the challenges faced, as well as the methods and approaches used to address them.

Presented by Deeksha Sinha, Research Scientist at Meta

What tech lies behind the social media giants’ attempts to keep content ”within the rules”? At Meta, we have both hand-crafted and learned risk models to flag questionable content, for humans to review. To operationalize these, we aggregate the different models to give a single ranking score, calibrating them to prioritize more reliable risk models. But violation trends change over time, affecting which risk models are most reliable; risk models change; and novel models are introduced. To continuously update the system in response to such trends, we use a contextual bandit. Our approach increases Meta’s top-line metric for measuring the effectiveness of its content moderation strategy by 13%.

In the Python open-source eco-system, many packages are available that cater to:

– the building of great algorithms

– the visualization of data

– back-end functions

Despite this, over 85% of Data Science Pilots remain pilots and do not make it to the production stage.

In this tutorial talk, we will demonstrate the usage of the Taipy, a new open-source offering we developed. With Taipy, Data Scientists will be able to build great pilots as well as stunning production-ready applications for end-users.

Taipy provides two independent modules: Taipy GUI and Taipy Core.

1. Taipy-GUI goes way beyond the capabilities of the standard graphical stack.

2. Taipy Core provides a simple yet very powerful execution framework for Optimization execution pipelines.

We hope that this contribution will support an easier and faster adoption of the data science and operations research solutions by end users.

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.
