Abstract-Hot rolling is the key process that convert cast or semi finished steel into finished products. Since the rolling operation is very costly, hence quality control of rolling process is essential. The raw material of leaf spring i.e. strip of SUP 11 is manufactured with hot rolling process. Any defect in the material may result rejection of final product that leads to major loss in terms of money and sometimes major accidents also. In this paper, the concept or voice of customer of India has been developed and shown the internal customer relationship among the various flow processes to achieve the full satisfaction of internal customer that leads to the satisfaction of external customer. Internal customer's job is to look after proper functioning of the process and minimization of the defects in the final process which leads to minimization of defects in the final product. Different defects have been taken into consideration by using Juran seven quality tools & New Seven quality tools, like Brain Storming, Cause and Effect diagram, Pareto analysis, problem solving session etc. to diagnose the root cause of the defect and accordingly corrective measures have been suggested.Index Terms-Hot rolling, internal and external customer, juran quality tools, leaf spring, SUP 11.
This paper develops a technique by using Jaya algorithm and feed-forward neural network to determine the quality of object-oriented software by using Chidamber & Kemerer (CK) along with Li & Henry metrics. The technique basically focuses on the maintainability factor of software quality which in turn depends upon the software complexity. The software complexity is directly proportional to the number of changes done per class which is determined by the technique. The analysis has been done on UIMS (User Interface Management System) and QUES (Quality Evaluation System) datasets by using the mean absolute error as the analysis parameter. The reduction in the mean absolute error as compared to the existing state of art techniques along with the individual component of proposed technique proves the significance of the technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
