The vector stencils library "Process annotations" contains 22 symbols of interface points, slope, off-sheet labels, callouts and textboxes.
Use these shapes for setting automatic labels to display a datasheet field for a pipeline shape, labels, captions, outlines, off-sheet labels, text balloons, annotations, outlines, tags, and descriptions.
"In engineering a process is a set of interrelated tasks that, together, transform inputs into outputs. These tasks may be carried out by people, nature, or machines using resources; so an engineering process must be considered in the context of the agents carrying out the tasks, and the resource attributes involved. Systems Engineering normative documents and those related to Maturity Models are typically based on processes. For example, System Engineering processes of the EIA-632 and processes involved in the Capability Maturity Model Integration (CMMI) institutionalization and improvement approach. Constraints imposed on the tasks and resources required to implement them are essential for executing the tasks mentioned.
A chemical process is a series of unit operations used to produce a material in large quantities.
In the chemical industry, chemical engineers will use the following to define or illustrate a process:
Process Flow Diagram (PFD),
Piping and instrumentation diagram
(P&ID),
Simplified process description,
Detailed process description,
Project management,
Process simulation." [Process (engineering). Wikipedia]
The example "Design elements - Process annotations" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Chemical and Process Engineering solution from the Engineering area of ConceptDraw Solution Park.
