Learning to Approximate Industrial Problems by Operations Research Classic Problems

open access: yesOperational Research, 2021
Operations research (OR) practitioners are accustomed to dealing with variants of classic OR problems. Indeed, an industrial problem often looks like a traveling salesman problem, a vehicle routing problem, a shortest path problem, etc., but has an ...

An Imitation and Heuristic Method for Scheduling with Subcontracted Resources

open access: yesMathematics, 2021
A scheduling problem with subcontracted resources is widely spread and is associated with the distribution of limited renewable and non-renewable resources, both own and subcontracted ones based on the work’s due dates and the earliest start time ...

Inventory Routing Analysis for Maritime LNG Supply of German Ports

open access: yesTransport and Telecommunication, 2021
After the implementation of Emission Control Areas (ECA) in Northern Europe in 2015, ship operators have to decide for new compliance methods. Among different abatement technologies, also the use of LNG as maritime fuel is one option.

Operations research games: A survey [PDF]

open access: yesTop, 2001
This paper surveys the research area of cooperative games associated with several types of operations research problems in which various decision makers (players) are involved.Cooperating players not only face a joint optimisation problem in trying, e.g., to minimise total joint costs, but also face an additional allocation problem in how to distribute

Machine Learning-Guided Dual Heuristics and New Lower Bounds for the Refueling and Maintenance Planning Problem of Nuclear Power Plants

open access: yesAlgorithms, 2020
This paper studies the hybridization of Mixed Integer Programming (MIP) with dual heuristics and machine learning techniques, to provide dual bounds for a large scale optimization problem from an industrial application.

Synchromodality in the Physical Internet – dual sourcing and real-time switching between transport modes

open access: yesEuropean Transport Research Review, 2019
Synchromodality, also referred to as “synchronized intermodality”, employs multiple transport modes in a flexible, dynamic way in order to induce a modal shift towards more environmentally friendly transport modes like rail or inland waterways, without ...
