A cumulative flow diagram is a tool used in queuing theory. It is an area graph that depicts the quantity of work in a given state, showing arrivals, time in queue, quantity in queue, and departure. According to the Project Management Body of Knowledge (7th edition) by the Project Management Institute (PMI), Cumulative Flow Diagram (CFD) is a ...
Traffic flow. In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement ...

Standard normal table. In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution. It is used to find the probability that a statistic is observed below, above, or between values on the standard normal ...
Control charts are classified into Shewhart individuals control chart (ISO 7870-2) [2] and CUSUM(CUsUM)(or cumulative sum control chart)(ISO 7870-4). [ 3 ] Control charts, also known as Shewhart charts (after Walter A. Shewhart ) or process-behavior charts , are a statistical process control tool used to determine if a manufacturing or business ...
In statistics, a moving average ( rolling average or running average or moving mean [1] or rolling mean) is a calculation to analyze data points by creating a series of averages of different selections of the full data set. Variations include: simple, cumulative, or weighted forms. Mathematically, a moving average is a type of convolution.
