| An occurrence is in its widest sense anything that happens. This includes human activities, but also physical and (bio)chemical processes, control processes, events and physical phenomena. Processes includes both discrete processes and continuous processes. A discrete process consists of a sequence of discrete process steps or actions. Examples of discrete processes are business processes in which various persons provide a contribution in the process, mechanical production processes in the mechanical industry and batch processes in the chemical industry. A continuous process is a process that is an operation on a continuous stream of raw material to produce one or more continuous streams of product materials. Examples of continuous processes are the flowing of water in a river, the operation of an electric power generation plant and the various refinery processes. An occurrence in fact always happens over time, but in some cases, such as events, the duration can be neglected. All these kinds of occurrences can be modeled in Gellish in a similar way. | An occurrence is in its widest sense anything that happens.
