Women Just Wanna Have OR: Young Researchers Interview Expert Researchers
Operations Research Forum - Tập 2 - Trang 1-14 - 2021
Is the gender gap still a topic in the academic world and in particular in Science, Technology, Engineering, and Mathematics (STEM)? What difficulties did women who pursue a career in academia have to overcome? What are the differences among countries and what has changed compared to the past? As women and members of a community of young researchers in Operations Research (OR), we have tried to fi......
An R Package for Generating Covariance Matrices for Maximum-Entropy Sampling from Precipitation Chemistry Data
Operations Research Forum - Tập 1 - Trang 1-21 - 2020
We present an open-source R package (MESgenCov v 0.1.0) for temporally fitting multivariate precipitation chemistry data and extracting a covariance matrix for use in the MESP (maximum-entropy sampling problem). We provide multiple functionalities for modeling and model assessment. The package is tightly coupled with NADP/NTN (National Atmospheric Deposition Program/National Trends Network) data f......
Scoring a Goal Optimally in a Soccer Game Under Liouville-Like Quantum Gravity Action
Operations Research Forum - Tập 4 - Trang 1-39 - 2023
In this paper, we present a new stochastic differential game-theoretic model of optimizing strategic behavior associated with a soccer player under the presence of stochastic goal dynamics by using a Feynman-type path integral approach, where the action of a player is on a
$$\sqrt{8/3}$$

Analytical Solution to the Radiotherapy Fractionation Problem Including Dose Bound Constraints
Operations Research Forum - Tập 3 - Trang 1-30 - 2022
This paper deals with the classic radiotherapy dose fractionation problem for cancer tumors concerning the following goals:
We will assume the linear-quadratic model to characterize the radiation effect without considering the tumor repopul......
Exploring Teacher Perceptions and Influencing Factors in the Inclusive Education of Students with Autism: A Comprehensive Analysis
Operations Research Forum - Tập 5 - Trang 1-25 - 2024
Emphasizing the critical need to recognize distinctive learning requirements, the study investigates practical applications of inclusiveness within mainstream classrooms. The objective is to explore, observe, and analyze Greek teachers’ perceptions and attitudes regarding inclusive education for children with ASD. Using a quantitative approach, the study employed questionnaires distributed across ......
A Basic Time Series Forecasting Course with Python
Operations Research Forum - Tập 4 - Trang 1-43 - 2022
The aim of this paper is to present a set of Python-based tools to develop forecasts using time series data sets. The material is based on a 4-week course that the author has taught for 7 years to students on operations research, management science, analytics, and statistics 1-year MSc programmes. However, it can easily be adapted to various other audiences, including executive management or some ......
Teaching Mathematical Modelling and Programming with GAMS in Dual Management Master Curricula Using Flipped Classrooms and Open Book Exams
Operations Research Forum - - 2022
In this article, we present a flipped classroom based teaching concept and related open book exam for Master’s courses in the field of Operational Research while paying particular attention to dual curricula management students. The characteristics of dual curricula include that students study part-time complemented by practical stages in cooperating firms. As a consequence, there is a limited num......
Finding a Portfolio of Near-Optimal Aggregated Solutions to Capacity Expansion Energy System Models

An Optimization-Based Decision Support Tool for Incremental Train Timetabling
Operations Research Forum - Tập 4 - Trang 1-20 - 2023
We consider the typical workflow of a route planner in the context of short-term train timetabling, that is, the incremental process of adjusting a timetable for the next day or up to the next year. This process usually alternates between (1) making rough modifications to an existing timetable (e.g., shifting the departure of a train by half an hour) and then (2) making small adjustments to regain......
Management of Wind Power Variations in Electricity System Investment Models
Operations Research Forum - Tập 2 - Trang 1-30 - 2021
Accounting for variability in generation and load and strategies to tackle variability cost-efficiently are key components of investment models for modern electricity systems. This work presents and evaluates the Hours-to-Decades (H2D) model, which builds upon a novel approach to account for strategies to manage variations in the electricity system covering several days, the variation management w......
