MODEL CATEGORY: Models come in different forms and shapes. These include:
- Graphical.
- Descriptive.
- Mathematical.
- Symbolical.
Each of the above or a combination of them can be used to represent an abstraction of real world entities in light of properties (structures), states, and interactions (events) within a context or domain of discourse.
Graphical
IDEF0, IDEF1X, and UML are the primary graphical modelling languages used in the "Prototype Edition" of EARN. Read an article on the account of evolution of graphical modelling language. BPMN and other graphical modelling languages will be incorporated over time.
Descriptive
Models of this nature are narrative or sentential formal logic.
Mathematical
An example of this model category is EVM formulae.
Symbolical
Chemical formula (e.g. H2O) is an example of symbolic model.
GENERIC DECOMPOSITION MODEL
Product
A product can be decomposed into components; each component consists of modules; and each module contains parts as shown in the following diagram.
Work
Work can be decomposed into processes. Each process can be partitioned into activities. An activity consists of one or more tasks as shown in the diagram below.
