ONE MORE STEP TOWARDS ENTERPRISE INTEGRATION
Model Driven Shop Floor Operation Control and Monitoring based on CIMOSA - Open Systems Architecture for CIM
RWTH Aachen, February, 1994: Integration in manufacturing becomes a reality at the shop floor of the Aachen Teaching Factory. Driven by a model of the order process for small batch size production, mechanical parts are produced according to priorities of incoming orders and the current capabilities of the shop floor. The CIMOSA-based model is engineered for ease of use providing high flexibility in order execution.
The ESPRIT Project AMICE presented its final results on CIMOSA in an open workshop held at the Teaching Factory (ADITEC) in Aachen, describing the use of the AMICE Project in enterprise engineering and enterprise operation control and monitoring. CIMOSA implementations at FIAT and WZL were presented and demonstrated. Pre-product versions of modelling tool developments were also presented by several Consortium members.
CIMOSA was used to optimize a FIAT gearbox production and assembly operation including both material and logistics flow. Different production strategies were simulated in the same model showing the benefits of a mixed push-pull production strategy compared with a pure Kanban implementation. CIMOSA demonstrated excellent business benefits compared with other state of the art business modelling approaches. These benefits were quantified in significant reduction in the time to model these strategies and simulate their effects of the business.
WZL used CIMOSA to model and simulate the complete order cycle for small batch size product families. This included order entry, product planning, production, distribution, and invoicing. Again, CIMOSA demonstrated its abilities to test out different solutions and its flexibility to handle different application areas like business process re-engineering, lean organization, total quality management, and control.
CIMOSA has been used at WZL also for model-driven shop floor operation control and monitoring. The CIMOSA Integrated Infrastructure (IIS) enabled business process control in a heterogeneous IT environment. The IIS implementation used OSF/DCE (Open System Foundation/ Distributed Computing Environment) as a common platform on hardware and software from different IT vendors, including Hewlett Packard, IBM, and Siemens Nixdorf. The integration of order processing, MRP-II based production planning, shop floor production planning refinement and manufacturing process control and monitoring was the major part of the demonstration. The order flow between the different operation steps was shown in a presentation via large screen projection. Following this presentation, the order was actually executed on the shop floor. This involved manufacturing the parts with milling, drilling, turning processes as well as the use of automated guided vehicles for transportation between process stations.
The CIMOSA specification will be maintained in the future by the CIMOSA Association: a newly formed group that was announced at the Aachen Workshop. Founding members of this group are industry and research organizations from ESPRIT Consortium AMICE. The CIMOSA Association will engage itself in the controlled evolution of the CIMOSA specification and information dissemination to the general public and to national, European, and international standards bodies. Application for membership is encouraged for any organization involved or interested in CIMOSA.
