A process flow diagram (PFD) is a visual representation of the steps, inputs, outputs, and resources involved in a process. It can help you identify inefficiencies, bottlenecks, risks, and ...

In this paper, we propose a cumulative flow diagram (CFD) estimation and prediction method using sampled vehicle trajectories. It can be used to calculate multiple performance measures—traffic volume, ...

This paper describes a diagramming methodology, referred to as an Object Flow Diagram (OFD), that is intended to be a key component in the conceptual design of a discrete-event simulation model. It ...
