P Diagram Example

Visualized in a simplistic manner.

P diagram example. What does a p diagram look like. Approved for public release. System elements und their functions are described and.

It is the ideal starting point of the fmea. A p diagram can also be used when preparing for a component fmea if the fmea team believes there is sufficient value in visually representing inputs ideal response and noise control factors. Input signals are a description of the energy sources required for fulfilling the system functionality such as speed acceleration input torque etc.

The parameter diagram p diagram takes the inputs from a system customer and relates those inputs to desired outputs of a design that the engineer is creating also considering non controllable outside influences. 3 aarx 304l s s 1 f 3 aarx 304l s s. Signal factor s response variable or ideal function control factors.

The p diagram can also prove valuable during transfer function determination chapter 13 in terms of initializing the identification of control and noise factors to use in an experimental design approach. It is most useful when the item being analyzed is a complex system with many system interactions operating conditions and design parameters as it helps the fmea team to visually see these elements. The parameter diagram p diagram is a block diagram which shows the connections between different parameters of a system.

The p diagram is a useful tool in brainstorming and documenting. Spec breaks a line code changes every time any element in the code changes ie 3 aarx 304l s s 1 f 3 aarx 304l s s at the point where the fluid has cooled enough to eliminate the insulation. The following is an example of a p diagram with an explanation for each of the elements.

Creating a p diagram is an optional step when preparing a system or subsystem fmea. The following is an example of a p diagram with an explanation for each of the elements. The p diagram will also prove valuable during optimization chapter 14 for evaluating and optimizing robustness against the noises.
