Cyber Physical Systems for Life Cycle Continuous Technical Documentation of Manufacturing Facilities

Abstract

Continuous rising of requirements to create technical documentation results in high effort in terms of time and costs to create a complete and up to date documentation for manufacturers. In case of any technical modifications of machines the technical documentation also has to be updated. In fact these updates are lacking in most cases.

In this paper, the authors propose a methodology for a self-organized creation of technical documentation to enable an up to date state throughout the Product Life Cycle. A complete and up to date technical documentation provides benefits to customers as well as suppliers of manufacturing facilities. The new approach is based on integration and communication of all components and modules such as machine tool, transportation and handling technology etc. via “Cyber Physical Systems”.

۱ Introduction

The accelerating global economy demands increasing product variety and shortened Product Life Cycles (PLC) for all kinds of consumption goods. To cope with these challenges, manufacturers need to reduce the production costs and the time to market by creating an adaptable and flexible production. Products in machinery and plant engineering need to become more flexible, while their complexity rises continuously.

In course of this the requirements to create technical documentation rise continuously. For manufacturers, this results in high effort in terms of time and costs to create a complete and up to date state on delivery. After delivery and initial startup of manufacturing facilities the technical documentation often cannot be kept up to date. Updates in consequence of technical modifications or upgrades arising from product change, optimization or production volume adjustment are lacking. In most cases, these modifications are undocumented or, in best case, added as separate documentation. While arising in particular during the critical phase close to delivery of manufacturing facilities additional personnel capacity required for preparing the technical documentation has a large impact on total costs. In addition the planning and performing of maintenance and service tasks based on an up to date and accurate documentation is an important factor for staying competitive for suppliers. To satisfy manufacturer´s and customer´s needs in engineering, new approaches for creating and using technical documentation are required.

In this paper, the authors propose a methodology for a selforganized creation of technical documentation to enable an up to date state throughout the PLC. The new approach is based on networking of all components or modules via Cyber Physical Systems (CPS).
