Quality of Products and Process Control...

Quality of Products and Process Control A product is said to be of desired quality when it complies with the specification as well as customer’s requirements and expectations and when it displays basic, performance and excitement functionalities. Products are produced by manufacturing processes. Also, quality cannot be tested into the product. It is to be built in the product by the manufacturing process during its manufacturing. One of the main factors which affect the quality of the product is the quality of the manufacturing process which produces the product. Sound and reliable processes produce quality products. Hence improving the quality of the manufacturing processes is a precondition for better product quality at an acceptable cost. Process as used in the terms process control and process industry, refers to the methods of changing or refining raw materials to create end products. Process control refers to the methods that are used to control process variables when manufacturing a product. Organization controls the production process for three reasons namely (i) reduce variability, (ii) increase efficiency, and (iii) ensure safety. Process control can reduce variability in the end product, which ensures a consistently high-quality product. Manufacturing processes have the many features which fall into one of the following categories Procedures – These are a series of steps followed in a regular, definite order. Methods – These are an orderly arrangement of a series of tasks, activities, or procedures. Equipment and supplies – These are physical devices and other hard goods which are needed to perform the process Materials – These are tangible elements, data, facts, figures, or information needed which along with equipment and supplies make up inputs required. People – They are numbers of individuals, skills they require, goals, and tasks they perform. Training – It is...

Process Control System...

Process Control System A process is broadly defined as an operation that uses resources to transform inputs into outputs. It is the resource that provides the needed energy to the process for the transformation to occur. In the context of an industry the term ‘process’ as used in the term ‘process control’ refers to the methods of changing and refining of raw materials that remain in a solid, liquid, gaseous, fluid or slurry state  to create end products of specified properties. The raw materials during the process are transferred, measured, mixed, heated or cooled, filtered, stored or handled in a way so that the desired output is obtained. During the process the raw materials undergo physical and chemical changes for their conversion into the end products. Normally an industry operates a number of processes where each process exhibits a particular dynamic (time varying) behaviour that governs the transformation. The dynamic behaviour is determined by the physical and chemical properties of the inputs, the resource and the process itself. Process control refers to the methods that are employed for controlling the variables of the process or processes used in the manufacturing of a product. It is the act of controlling a final control element to change manipulated variable to maintain the process variable at a desired set point. These variables can be in process inputs, in process parameters and in process output. Control of the process is done to reduce its variability for getting aimed product quality, improving the production rates, increasing the efficiency of the process, facilitating protection of the environment and ensuring safety of the men and equipment employed for the process. A corollary to the process control is that a controllable process must behave in a predictable manner. For a given change...

Managerial Process Control...

Managerial Process Control A process is broadly defined as an operation that uses resources to transform inputs into outputs. It is the resource that provides the needed energy to the process for the transformation to occur. In an organization there are two types of processes. One are those processes that create, produce, and delivers products and services while the second type of processes are those which do not produce outputs bur are still necessary in the functioning of the organization. The first group of the processes can be called work processes while the second type of the processes can be called administrative processes. Both the types of the processes are important for the functioning of the organization and need adequate process control activities for their successful implementation. In process control, two types of variable exist. They are manipulated variables which can be adjusted and the controlled variables which are affected by the adjustments. Process control is an important function of the management of an organization. Through process control it is ensured that the activities are under control and are giving the desired results. Process control determines that all the management processes are controllable processes that behave in a predictable manner. It shows that for a given change in the manipulated variable, the process variable responds in a predictable and consistent manner. Process control refers to the methods that are employed for controlling the variables of the management process. It is the control process through which managers assure that actual activities conform to the planned activities. Process control finds out the deviations between the actual performance and the standard performance for taking the necessary steps to prevent such variances in future. It also measures the current performance and guides it towards some predetermined objectives. It...
