Conclusion

PML, an Object Oriented Process Modeling Language 155

instantiated or enhanced without losing compatibility to the approved generic process.

To document the instantiation of processes use case diagrams can be used to describe reference instantiations and interactions of projects and sub projects without actual instantiation of a project.

This paper has shown the concepts of the new process modeling language PML.

Deriving PML mathematically from UML led to a process model that supports object oriented process modeling capabilities. Thus the requirements for a modern process description language have been fulfilled, such as modularization, exchangeability, cross enterprise collaboration, easy maintenance, enhance ability and many more.

This paper has introduced and discussed many new diagram types that are known from UML. The usage of PML has been shown with a complex example that illustrates the strength of this process modeling language. Thus the basic work for the usage of PML in productivity has been done.

Abstract: To achieve different assembly operations on the aircraft structure, the aeronautic OEM needs to create and manage various fixture tools. To cope with these needs, the OEM begun to adopt the supplier integration into the tooling de-velopment process. This paper presents a conceptual PLM-based approach to sup-port new business partnership of different suppliers. The new business partnership aims to improve the role of supplier in the different tasks of design, configuration and fabrication of the tooling. The use of the PLM concepts is proposed to en-hance the collaboration between OEM and the equipment's suppliers. UML mod-els are proposed to specify the structure of the PLM solution. These modmod-els de-scribe the relation between the aircraft assembly project, and the tooling design process.

1. Introduction

The role of supplier in a successful assembly process of aircraft component is very important. Because of the specific aircraft structure, assembly department needs to constantly design new fixture tools used for new assembly operations. It obviously happens when the aeronautic OEM creates new aircraft model, and also when this OEM modifies the existing models to satisfy a particular customer requirement.

To deal with assembly tool costs and time to market optimization challenges, the collaboration between OEM and suppliers should rather go into strategic

part-nership, covering the whole tool’s lifecycle. The purpose of our research is to de-velop a new business partnership that enables efficient collaboration between OEM and suppliers. This partnership would enhance the suppliers’ role in the de-sign process of assembly tools. The case study concerns the tooling dede-sign activi-ties and manufacturing process in the aeronautic industry. The construction of this business partnership is obtained according the following perspectives:

• Definition of its mission and organization,

• Identification of new methodologies to optimize it's operating processes,

• Realization of a collaborative IT framework to support its activities.

The paper focuses on the last perspective and describes a conceptual framework to specify an innovative PLM-based approach. The originality of our approach comes from the high abstraction level of the proposed models based on the situa-tion concept. These concepts are useful to describe different organizasitua-tion forms. It mainly provides specification of IT system that can gives innovation aided by en-hancing the project organization in the context of extended enterprise and by fa-vouring interoperability between heterogeneous information shared between OEM and supplier systems (for instance, between SAP system to capture Aircraft infor-mation at the OEM level and DELMIA system to identify the tooling behaviour in the assembly process, at the supplier level).

First, we present an overview of the context study and the interest of PLM ap-proach to solve this problematic. Second, a literature review is presented concern-ing the use of PLM methodologies to support the OEM supplier partnership.

Third, we develop our conceptual models of the IT structure. The specification of the PLM-based approach is defined according to a unified modelling that de-scribes, at the same abstraction level, the product (assembly tools or equipment) data and process data. Fourth, the concept of project view is presented. Using the UML activity diagram, we detailed some functionalities of the future collaborative system to manage the equipment design project.
