Balancing Bicycle Sharing Systems

Mon, 01 Jan 2024 00:00:00 +0000

Public bicycle sharing systems are booming worldwide in many major
cities. Such systems augment public transport very well, are green
alternatives to motorized individual traffic, may decrease traffic jams
and parking problems in cities to a certain extent, and last but not
least are an incentive for sports and a significant contribution to
public health. Modern systems have automated rental stations
distributed over the (inner) districts of the city, and users can easily
rent bicycles and bring them back at any other stations.

For user acceptance it is essential to provide enough bicycles as well
as parking slots for returning them at any station at almost all time.
As the usage pattern typically is not symmetric, e.g., people tend to
rent bikes at topographically higher stations and return them to lower
stations, an active maintenance by regularly transporting bikes from
some stations to others is crucial.

Project partners:

Problem Definition

The balancing bike sharing systems (BBSS) problem consists of finding an optimal rebalancing plan for the operator that consists of

a route for each vehicle on duty and
loading instructions for each station on the route

so that the system is in a balanced condition afterwards, i.e., no station is overly full or empty.

Two basic problem variants are considered:

Static case: The rebalancing process is done when the system is not used (e.g., overnight). Initial and target station fill levels are given as constants.
Dynamic case: The system is rebalanced while in use. Station fill levels are time-dependent and estimated by empirical data.

Approaches

Exact approaches based on mixed integer programming:

Hop index model
Time index model

Construction heuristics:

Greedy heuristic
PILOT heuristic

Metaheuristic approaches:

Variable neighborhood search approach
GRASP approach
Hybrid of GRASP with Path Relinking

Problem instances which we are using for our work can be found here.

Complete Solution Archives for Evolutionary Combinatorial Optimization

Mon, 01 Jan 2024 00:00:00 +0000

Benjamin Biesinger
Bin Hu
Günther Raidl

A common drawback of metaheuristic approaches, especially evolutionary algorithms (EAs) is that they usually do not keep track of the search history, and already evaluated solutions are often revisited. This leads to premature convergence, wasting resources for re-evaluations, and other malicious effects.

The solution archive (SA) is a concept for dealing with this problem. By attaching it to a classical EA, it enables detecting already evaluated candidate solutions and efficiently transforming them into similar but yet unvisited solutions, i.e., performing an “intelligent mutation”. The figure above illustrates the cooperation between the EA and the archive.

Application

Since this concept causes additional overhead for inserting and transforming solutions in the SA data structure, following conditions should hold in order to maximize the efficiency:

A compact solution representation keeps memory consumption for the archive low.
Problems with expensive solution evaluations benefit most from avoiding re-evaluations.
Problems with few feasibility constraints so that the transformation procedure can be kept simple.

Following combinatorial optimization problems were particularly successful with this approach:

Royal road functions
NK landscapes
Generalized minimum spanning tree problem
(r|p)-centroid problem and other competitive facility location problem

Cooperative Optimization Approaches for Distributing Service Points

Mon, 01 Jan 2024 00:00:00 +0000

Topic

For many business models an optimal distribution of service points in a customer community is needed. Examples are charging/battery swapping stations of electric vehicles, bicycle/car sharing stations, and repair stations. When planning such systems, estimating under which conditions which customer demand can be fulfilled is fundamental in order to design and evaluate possible solutions. To this end, demographic data is usually interlinked with geographic information, data on public transport, the street network, knowledge on manifold special locations etc. Usually, the whole process is challenging and error-prone. Customer demand information determined in such ways typically is vague, and not uncommonly a system built on such assumptions is not as effective as originally hoped for due to major deviations in reality.

To possibly improve this situation, we propose a cooperative optimization approach that incorporates potential users on a large scale and more tightly into the data acquisition as well as the optimization process. We confront the potential customers with certain location scenarios and ask them how these would suit his needs and how possibly these scenarios can be improved to fulfill more of his demand. This feedback is used to incrementally gain more knowledge about how much demand may be fulfilled under which conditions. New, more promising candidate location scenarios can then be derived and again be presented to the users. The process is iterated on a large scale with many potential users and many rounds until a satisfactory solution is reached.

The figure below depicts the components of the framework of our cooperative optimization approach and their interaction. The general framework consists of the following components: an evaluation component (EC), an optimization component (OC), a feedback component (FC), and a solution management component (SMC).

Cooperative Personnel Scheduling

Project Team

Topic

In classical personnel scheduling, the employees of a company are assigned their schedules, which determine at which times they work to fulfill some kind of demand. Our setting is slightly different. Each employee also referred to as a user, has some jobs to complete that need a specific resource. Only a limited amount of resources is available and only one job can use a resource at a time. Each job has to be assigned to a resource and a timespan in which the job is carried out. Furthermore, users will have preferences on when their jobs should be executed. These preferences have to be collected in some way. One possibility would be to let the employees specify their full preferences in the beginning. But this is tedious for the employees, error-prone and only allows for preferences that were explicitly considered when designing the algorithm.

In this project, we will develop and investigate a framework that learns these preferences over time through a limited amount of user interactions. The framework aims to construct schedules that respect employees’ preferences and are feasible with the given restrictions. While constructing the schedules it is allowed to ask the employees a limited number of questions regarding their preferences. The responses to these questions are used to model the employees’ preferences. The framework may also consider fairness, e.g. by balancing the number of user interactions among the employees. Research questions to answer include which algorithms work well for the occurring problems, how to model the employees’ preferences, and which kind of user interaction gives sufficient information on the preferences, without overwhelming the employees.

Cutting and Packing Problems

Mon, 01 Jan 2024 00:00:00 +0000

Frederico Dusberger
Günther Raidl

Cutting and packing problems occur in a multitude of industrial or other real-world applications such as

glass, paper and steel cutting,
container or pallet loading,
VLSI design,
and many other applications.

Usually items have to be cut from raw material and waste should be minimized, or the number of bins/containers needed to pack given items has to be minimized. In our research we dealt (until now) with two-dimensional bin packing problems where only guillotineable cutting/packing patterns are allowed.

Another kind of packing problems are the so called Knapsack Problems. Where items with an associated profit have to be packed into one or more knapsacks, and the profit has to be maximized. There are several variants of knapsack problems, such as the classical knapsack problem, multiconstrained knapsack problems, multiple knapsack problems, and many others. In our research we mainly deal with multiconstrained knapsack problems.

Solving cutting and packing problems can be done in various ways, we developed metaheuristics and exact algorithms for dealing with those problems. Especially the combination of evolutionary algorithms with problem specific heuristics, local and global optimization techniques are considered. Please see also our page on metaheuristics and evolutionary computation and the page on hybrid optimization techniques.

Large-Scale Radio Therapy Scheduling

Mon, 01 Jan 2024 00:00:00 +0000

One of the most advanced medical centers for Ion Beam Therapy and Research in Europe is currently being built in Wiener Neustadt: MedAustron. The radiation therapies applied will use protons and carbon ions for cancer treatment. The first patient treatments are planned in 2016. In the full operational phase up to 1,200 people per year are expected to benefit from the international first class medicine offered by MedAustron.

Scheduling patient treatments with their large number of individual tasks and specific requirements in order to best utilize the available resources and treat patients as soon and smoothly as possible is a huge challenge. The Algorithms and Complexity Group collaborates with MedAustron in the development of advanced scheduling algorithms and their software implementation to fulfill these needs and to give as many cancer patients as possible a new opportunity.

Within the Algorithms and Complexity Group, Günther Raidl is leading this research effort.

Learning to Solve Dynamic Vehicle Routing Problems

a joined research project from the Algorithms and Complexity Group, TU Wien, Austria, and Honda Research Institute, Germany

Project Team

Topic

Vehicle routing - i.e., planning an optimal set of routes for a fleet of vehicles - is an intensely studied research area with enormous practical and raising relevance due to increasing mobility and transportation demand and new challenges coming, e.g., from increasing interest in shared mobility services and electric vehicles. The dial-a-ride problem (DARP), for example, is the problem of finding optimal tours of vehicles through different pickup and drop-off locations in order to serve a number of transportation requests, allowing different customers to share a vehicle. The electric autonomous dial-a-ride problem (E-ADARP) represents a challenging and practically relevant extension to the DARP, where electric autonomous vehicles are employed and their charging requirements have to be taken into consideration. Furthermore, not only classical objectives like total travel time have to be optimized, but user inconvenience also plays an important role. Thus, factors such as user excess ride time, which is due to detours because of the ride-sharing, have to be taken into account.

For such problems, heuristic optimization approaches are considered to be the means of choice due to a better scalability compared to exact approaches. In this project, we propose a heuristic framework based on large neighborhood search (LNS) to solve the E-ADARP, and we plan to tackle the issue of scalability by automatically designing, i.e., learning, efficient heuristics that either guide or possibly replace classical optimization techniques. We will investigate the usage of reinforcement learning with different machine learning models to dynamically select operators for the LNS from a set of possible operators during the optimization process. We intend to experimentally compare this approach to other learning techniques such as classical supervised learning, imitation learning, and Q learning.
