Quality
The quality rate can be expressed as the production input into the process or equipment minus the volume or number of quality defects then divided by the production input. The quality rate can be expressed in a formula as
Quality rate = ((production input – quality defects)/ Production input)* 100 (4)
The production input mean that the unit of product being feed into the production process. The quality defects mean the amount of products which are below the quality standards i.e. the rejected items after the production process. This formula is very helpful to calculate the quality problems in the production process [9].
