A logistical process tries to find the best solution for manufacturing and distributing goods by considering how the market uses these products. This PFD shows the grain logistics process. Though its concepts are sometimes applied to other processes, it is most commonly employed in chemical engineering and process engineering. It can be used to document, improve, or model a new process. A Process Flow Diagram can be used for a variety of reasons. 1. To document a process for better comprehension, quality control, and employee training. 2. To make a process more efficient and repeatable by standardizing it. 3. To examine a process in order to increase its efficiency. It aids in the identification of redundant stages, bottlenecks, and other inefficiencies. Download EdrawMax and start creating PFD diagrams.
