The Informationssystemarchitekur CIM-OSA (open of system Architecture for computer Integrated Manufacturing) developed under the research project No. 688 "AMICE "of the ESPRIT (European Strategic Program for Research and development in information Technology) program of the European community (today European union) and under the line of a consortium of prominent enterprises (among other things HP, Siemens, IBM, DaimlerChrysler) was developed. AMICE stands for European computer Integrated Manufacturing Architecture and pursues the goal of an open CIM architecture. In the center the process orientated modelling of production enterprises is located.

Dimensions of CIM-OSA

CIM-OSA differentiates between three dimensions:

1. stepwise derivation (gradual derivative)
2. stepwise instantiation (gradual rewriting)
3. stepwise generation (gradual generation)

These dimensions pursue a gradual refinement of the degree of abstraction of the model. The dimension stepwise derivation differentiates thereby three description levels of a phase conception (requirement definition, Design specification and implementation description). They describe the implementation process of the definition of the requirements up to the implementation.

In the context of the dimension stepwise instantiation a refinement is pursued industry-referred by general (towards Eric requirement) over (partial requirements) up to enterprise-individual (particular requirements) requirements.

As is the case for ARIS one introduced different sighting also with CIM-OSA. Also here the sighting partitioning is to increase the transparency of the model by the dismantling of the general context. It is differentiated between four sighting (Function View, information View, resources View and Organization View).

The function view, the most detailed view, contains a hierarchical breakdown of enterprise processes. Within this view the description of the structure and the behavior of these business processes take place. With the Konstrukten Domain Process, Businesses Process and Enterprise Activity the business processes on different degrees of detail are described. A Domain Process consists of a quantity of Enterprise Activities. There the Hilfskonstrukt Business Process is to group Enterprise Activities and structure their behavior.

If one joins the individual modules of the three dimensions, then the CIM-OSA cube with that, oft-quoted in this connection, develops the CIM-OSA architecture is plotted.

Problems

Due to the high complexity of the CIM-OSA of system and existing more powerful architectures CIM-OSA could never really become generally accepted. Appear problematic in particular the strict conceptional top down proceeding of the model production on the basis of generic components and the restriction of the solution on the range of application of the integrated industriellen production (CIM).

The model production effected in a structured, textuellen form under too the Templates placed from CIM-OSA to the order (English collecting mains). The extent of the Templates is enormous due to the complexity of the topic and becomes unclear thereby. Also the possibility of a graphic description is planned, but puts to CIM-OSA no graphic modelling method at the disposal.

Differently than with ARIS is missing also one level, which unites individual sighting again. In ARIS this is converted by the control view. From the absence of this layer laps in the descriptions result to that sighting. The description of resources contains for example also the allocation of resources to functions.
