Mathematical Methods and Operation Research in Logistics, Project Planning, and Scheduling, 2nd Edition

The present Special Issue of the MDPI journal Mathematics, titled "Mathematical Methods and Operation Research in Logistics, Project Planning, and Scheduling, 2nd Edition", contains a total of eight articles that cover a wide range of topics related to the theory, models, and applications of project planning, project scheduling, and operation research problems in logistics. These topics include, among others, scheduling problems, research allocation problems in project planning, routing and warehousing problems in logistics, and risk aggregation problems in risk assessments. It is hoped that the reprint will be interesting and useful for those working in the area of project planning, scheduling, routing, and other operation research and risk management problems in logistics. It is designed with people with mathematical backgrounds in mind, who are open to become familiar with recent advances of operation research and optimization problems. Each article reflects on novel challenges, such as pandemic situations and flexible, fast-changing environments.
