Tightly unifying scheduling into critical MES functions in Microsoft-based operations management system, cmNavigo v4.0 improves on-time delivery and shortens total cycle time. Integrated scheduling models plant floor resources and defines role of each in fulfilling mix of orders in optimal near-term time frame, driven by customer demand. It also avoids duplication of master data, allows real-time updates across different areas of plant floor, and eliminates need to maintain separate interfaces.
