3.1.3 EEML (Extended Enterprise Modeling Language)
EEML is originally developed in EXTERNAL project [59] to support development
and use of interactive models 1 . The technological approach in EXTERNAL involves
integration of several business process technologies, such as process-centric enterprise
modeling, computational simulation models, hypermedia collaboration tools and emergent
workflow tools. EEML is the research result of process-centric enterprise modeling.
EEML is created to support process modeling across the four layers of process models:
• Generic Task Type. Identifying the constituent tasks of generic, repetitive
processes and the logical dependencies between these tasks (so-called reference
processes).
• Specific Task Type. Expanding and elaborating process models to facilitate
business solutions. Elaboration includes concretization, decomposition, and specialization.
• Manage Task Instances. Detail planning, co-ordination and preparation for
resource allocation concerning actual work environment and process instance.
• Perform Task Instances. The actual execution of tasks according to the determined
granularity of work breakdown, which in practice is coupled to issues
of empowerment and decentralization. At this layer resources are utilized or
consumed, in an exclusive or shared manner.
EEML can be used for process and enterprise modeling on different levels (both
type and instance level). Type level related to generic task type and specific task type
layers are our interests. The language vocabulary of EEML is grouped into several
domains. In this work, we only concern two domains: EEML process domain and EEML
1 Interactive model: prescribed aspects of the model are automatically interpreted and ambiguous
parts are left to the users to resolve, with tool support [65].
