Capacity research is a field of study that focuses on understanding the maximum amount of resources, such as time, money, or energy, that an individual or organization can effectively utilize to achieve a specific goal or perform a certain task. This research area aims to identify the limitations and constraints that may impact an entity's ability to function optimally, and seeks to develop strategies and techniques to enhance capacity utilization and efficiency. Capacity research is often applied in various disciplines, such as business management, economics, operations research, and engineering, to inform decision-making and optimize resource allocation.
