What is the relationship between process control and quality?
In production, the quality of measuring acceptable final products in the fulfillment of specific goals that could include low -rejected products, minimal waste materials or a lower raw material rate. In order to set these objectives, processes management and quality must be interconnected in order for production facilities to operate in an acceptable limit. Process control must also include software or devices that can determine when the process is outside the limits or is directed in this way to make appropriate repairs.
The term “statistical process control” is often used for computer control systems developed since the end of the 20th century. Statistical control easily maintains the production process within the limits designed to provide the best statistical chance of a good finished product. Mathematical statistics can be used to determine the range of limits for different process control. The operation of a number of laboratory experiments and small -scale operations can then confirm the best control limits. Once statistical limits areSimilarly, control engineers can propose electronic equipment to provide the correct control and quality of the process.
Interest in processes in the 50th years increased because production with high volume during World War II showed the need for better quality and at the same time increased the production rate. In addition, countries with lower production costs could export more worldwide and replace local suppliers, which would lead to interest and quality control to reduce production costs. Smaller electronic components have become cost -effective for use in control systems in a later 20th century. This has led to the development of "intelligent" control systems that could analyze production variables and make independent adjustments.
Process and quality management was highly connected to the end of the 20th century and the larva of that time was developed by the number of statistical methods, including Six Sigma, Lean Manufacturing, CustomsQuality (TQM) and others. They all tried to create consistent methods for determining the quality and ways of controlling it, including raw materials, energy consumption and process safety costs. These systems were created to find ways to control quality during the process, rather than to change the procedural variables without understanding the effect on the final product.
As the cost of energy and carbon fuel increased at the end of the 20th century, the control and quality of the processes developed in the use of inspections to create good products and to minimize the impact of rising oil costs. At that time, many countries were strongly relying on oil, gas and coal on raw materials and energy production, resulting in a closely linked carbon -based product. Together with increased interest in energy efficiency, manufacturers continued to refine processes and quality Softrare and instrumentation to maximize the efficiency of all raw materials created from oil, fromof an emotional gas or coal.
