Embodiment Construction

[0050] figure 1 Shows the position of the proposed event-based reaction production order optimization method at the intersection of supply management according to EPCIS standard [4] and production operation management according to ISA95 / 88 [1], [2]. The proposed architecture seamlessly integrates cross-company tracking & tracking functions with the company's manufacturing operations management. In order to be able to respond to critical interruptions in the short term, the EPCIS-compatible event handling mechanism is used to extend the manufacturing execution system. The EPCIS-compatible event handling mechanism extension supports the identification of critical situations in the supply chain and triggers appropriate production schedule rescheduling.

Abstract

First inter-organizational tracking & tracing systems facilitate timely identification and handling of disruptions along the supply chain. However, these systems typically operate at Supply Chain Management (SCM) and Enterprise Resource Planning System (ERP) level and therefore lack knowledge and control over production processes. The invention bridges the gap between logistics and production IT by proposing a novel architecture for coupling the manufacturing operations as defined in IEC 62264 with an EPCIS-compliant real-time tracking & tracing system. The system leverages logic-based complex event processing for detecting critical disruptions in the supply chain and initiates rescheduling of production. It is shown that in the presence of unexpected events the rescheduling algorithm minimizes delays and inventory costs while avoiding «nervous schedules» caused by frequent changes.

Description

Technical field [0001] The present invention relates to a production management method in a manufacturing execution system (MES) according to claim 1 and a system for executing the method according to claim 9. Background technique [0002] In recent years, the trend of outsourcing and globalization in the automotive and other industries has led to increasingly fragmented production processes. These processes usually rely on long and complex logistics networks involving a large number of companies geographically distributed around the world. The increasing complexity of these processes leads to error-proneness, and therefore the uncertainty of suppliers’ goods arriving at the production facility in time. This uncertainty can be reduced by monitoring and recording the shipment of goods in real time along the supply chain. Recent developments in RFID and other Auto-ID technologies have promoted this tracking & tracking system. Since the logistics process usually involves several ...
