Statistical Process Control for the Food Industry

10Case Studies

This chapter disclosed the case studies gathered from research and literature. Each case study is described in brief, focusing on the application of the specific expediting process control approach it illustrates, including the approach to choose pilot projects, the control of key quality of the process attributes, and the application of various type of control charts served for different types of data. This chapter displays how SPC has been successfully applied in several different situations.

The details and situation of the cases are varied, however in general each will provide the background of the cases, the data and suitable type of charts. The charts are interpreted, and interesting points are discussed in the case study. It is not necessarily to understand the calculation and detail calculations to benefit from this book. Implementing SPC in the organisation, it only requires a few number staff to understand the theory and formulae on the calculations of control charts.

10.1 Application of the Control Charts in the Industries

Control charts are typically taught in the classes and mostly when teaching the theory of SPC it is understandable to find the data for the control chart are the easiest to be understood. Theoretically, normality is expected in the food processing data; however, this is rarely the case in the food industry. In the real‐world data, neither SPC nor any other technique is the solution for all problems, where other quality tools may ...
