Development of Web Interface, Server and Database for Intelligent Process Surveillance with focus on Geometry variations : Thesis for the degree of Bachelor of Science with a Major in Computer Science

Abstract: A car body part is assembled by different metal parts. These metal parts are always unique. The deviation affects the assembled component. When a body component has been assembled random samples are measured to validate that the deviation of the assembled component is within a certain tolerance level. If the component is outside the tolerance level an adjustment has to be done.   How to make an adjustment is knowledge based on experience. This kind of knowledge is named tacit knowledge and is difficult to be transferred or documented. A Case Based Reasoning system solves a target issue with a similar previous solution, similar to humans tacit knowledge. This system will, once it has enough knowledge, give an engineer a suggestion of how to adjust.   This thesis report describes the process to create a Case Based Reasoning system for Volvo Cars Body Components (VCBC) located in Olofström, Sweden. This thesis work is a part of an ongoing research project about how to make the body components production more effective in the future, a collaboration between Mälardalens University and VCBC. The main requirement of the thesis work was to develop a system that can be used to validate the research project.   A system was developed and installed, designed to operate on different production lines. The system consists of a website as a GUI and a Microsoft SQL Server for storing data. The main requirement is achieved.   Keywords: case based reasoning, production line, measurement data, adjustment data, database design, software engineering, Matlab deployment, .NET
