Types of control diagrams and their use in quality management

摘要

Statistical control charts (SPCs) are part of the preventive tools of quality management. Shewhart control charts, which have many limitations, are often applied to evaluate statistical processes. Conventional diagnostics of the manufacturing process can simply fail using this method. For this reason, other procedures must also be used to enable efficient process control in the existing production conditions. The paper presents an overview of the types and properties of the control charts with the focus on their applicability. In addition, the current issues in the field of standardization based on the applicability of different types of control diagrams are mentioned as well.
