The Logistics Management System (LMS) is a realtime imbedded transaction-based integrated decision and knowledge based expert support (RITIDES) system which serves as a "dispatcher" (monitor I and control) for the manufacturing flow or logistics of IBM’s semiconductor facility in Essex Junction, Vermont. Its purpose is to help improve manufacturing performance in tool utilization, serviceability, and cycle time. Significant success has been achieved in all areas. LMS is now a critical component in running major areas of the manufacturing facility. LMS was developed by the Advanced Industrial Engineering department as part of its mission to improve decision making through improved decision support.
