There are several scheduling procedures in use. We take the following scheduling example: 1. Shortest Processing Time (SPT) Procedure: A schedule obtained by sequencing jobs for production in non-decreasing order of processing times is called a shortest processing time (SPT) schedule. This schedule minimizes mean flow time F̅. In addition, the SPT rule also minimizes mean lateness and means waiting [...]
In this article we will discuss about the meaning and quality requirements of integrated quality assurance. Meaning of Integrated Quality Assurance (QA): The success of computer-integrated manufacturing (CIM) to a great extent depends on integrated quality assurance (QA) into the process. It is being realised that QA has to be an intimate element of every step in the design/ manufacturing/distribution [...]
In this article we will discuss about the independent input and dependent variables used in Production System. Independent Input Variables: Workpiece Material: It is selected to meet the functional design criteria. While some metals like cast iron, aluminium machine easily; others like stainless steel, titanium are difficult to machine. Part Geometry: The size and shape of workpiece is decided by [...]
