Researcher Portfolio

Chua Tay Jin (Mr)
Principal Research Engineer I
Planning and Operations Management
Introduction:Mr Chua Tay Jin has more than 22 years of working experiences in the area of manufacturing operations management related technologies. Since joining SIMTech, he has led several industrial and research projects in the areas of advanced planning and scheduling and enterprise resource planning and conducted several Technology Infusion Programme and Graduate Diploma courses in Advanced Planning and Scheduling for the past few years. He was appointed as the Manager for the Planning and Scheduling Application Centre (PSAC) on Oct 1998. The Centre has successfully completed several industrial projects for the Electronics and Precision Engineering industries. He is the chief inventor of the SIMTech's flagship advanced planning and scheduling software, the Gintic Scheduling System (GSS). The software has been successfully licensed to a local software company and the system has been implemented in several Semiconductor Backend Assembly companies in the region. He is currently spearheading an industry-wide effort on helping companies in the Precision Engineering industry by developing dynamic production scheduling software for high-mix low-volume manufacturing environment. To date, he had filed three USA patents and one Singapore patent in the area of production planning and scheduling. Out of these patent applications, three have already been granted. He is also the Course Leader for the Graduate Diploma in Manufacturing Operations Management (MOM) course and the Module Leader for the Advanced Planning and Scheduling (APS) module.
