**Preface to "Applications of Operational Research and Mathematical Models in Management"**

During World War I and World War II, many mathematical models were developed and used to solve various optimization problems related to the ongoing war operations. At the end of these wars, these models were applied to industry and business. Nowadays, operational research is a key tool of modern management that is used to solve a wide range of business problems.

The aim of this Special Issue was to discuss new theoretical insights into the applications of operational research and mathematical models in management.

Published papers explore operational research and mathematical models in business management, finance, decision support systems, tourism management, information technology, and artificial intelligence.
