Expert System Software for Production Planning and Quality Control in Bleaching Dyeing and Finishing Process of Textiles Industry

Abstract

The objective of this research is to develop the expert software to use for planning the production process and quality control. Starting from collecting the data of knowledge, and expertise experiences, to analyze, design, tests and record in systematic ways. By using the forward chaining inference and knowledge acquisition subsystem, writing with SQL and developing by Oracle to work on Unix server and exporting through Microsoft Excel for the convenient working. Process and decision procedures show after feeding the data into the system, for estimation and sending the results to program page. According to the set up pattern, experts spend 60 minutes for a piece of work manually. After introducing this system, experts are able to reduce time consumption by 98.33 %. Previously they spend 45 minutes/120 yards to check of fabric. Time consumption is reduced 55.55%, this means the increasing production result of 3,072 yards/day and the average cost is 61,440 baht/day. The investment is paid back within 26 days. This system can be used without experts who have estimation experiences. It does not need any specialized persons. This is the way to preserve the knowledge and solve the problems which may occur at the workplace. It is the foundation for managing the value added production system to be stable and sustainable.
