TOP is an international Journal of Operations Research created and supported by the Spanish Society of Statistics, Operations Research and Data Science. TOP publishes original papers that significantly contribute to the theory and methodology of Operations Research, or the practice of Data-Driven Decision Making through innovative applications of Operations Research. TOP considers the following types of papers for publication: • Invited Reviews written by leading scholars and invited by the Editors-in-Chief, describing the state of the art as well as future lines of research for a broad and timely Operations Research (OR) topic. Multiple discussants with leading expertise in the topic are invited to write a short piece with comments on the review, which are published alongside a rejoinder written by the authors. • Theory and Methodology Papers, presenting original research results contributing to the methodology of OR and its theoretical foundations. • Innovative Applications Papers, presenting novel ways to solve real-world problems with state-of-the-art OR techniques. TOP does not accept proposals for guest-edited issues. When submitting a paper for consideration, the authors will need to choose from a comprehensive list of Keywords: Bioinformatics Combinatorial Optimization Conic programming and interior point methods Continuous Optimization Cutting and Packing Data Science and Machine Learning Decision Theory Dynamic Programming Efficiency and Productivity Analysis Forecasting Fuzzy sets Game Theory: cooperative games Game Theory: non cooperative games Global Optimization Graphs and Networks Heuristics Large Scale Optimization Location Logistics, Transportation and Distribution Planning Manufacturing, Production and Retail Operations Planning Metaheuristics Mixed Integer (Linear and Nonlinear) Optimization Multiple Criteria Analysis and Multiobjective Optimization Nonlinear Optimization OR and Education OR in Energy OR in Finance OR in Health Services OR in Humanitarian Operations OR in Natural Resources, Agriculture and Forest Management OR in Sports Parallel Computing, Distributed Computing, and Vector Processing Pricing and Revenue Management Project Management Queueing and Stochastic Models Reliability and Maintenance Risk Management Robust Optimization Routing Semi-infinite programming Sequencing and Scheduling Simulation Software, Benchmarks, Numerical Experimentation and Comparisons Stochastic Optimization Supply Chain Management Sustainable OR Officially cited as: TOP .
