Abstract: Coordination and optimization for an operational system aims to improve the operational efficiency of the system and its ability to cope with uncertain environments. This kind of research problem is characterized by nonlinearity, multiple objectives, variable structures and uncertain information, and has always been a hot and difficult topic in operations management. By taking the theoretical and practical problems in operations systems as the research subject, in-depth research was conducted from the perspectives of demand forecasting, system design, operations and risk control. Specifically, focus was laid on non-stationary demand forecasting and decision-making, supply chain coordination and integrated design, as well as risk prediction and control for operations systems. Some original results have been obtained, which to some extent promote the development of the research in corresponding directions.

Key words: operations system, demand forecasting, coordination and optimization, integrated design, risk control
