REA ontology, Production planning, Process modeling, Value chains, Business semantics
The paper focuses on the enterprise production plan at operational level modeling using the Resource-Event-Agent (REA) modeling framework. The REA modeling framework belongs to value oriented perspective modeling tools rather than to process oriented perspective modeling tools. Its prevailing application area has been accountancy domain. The aim of the paper is to utilize this framework also to other standard domains. Enterprise production planning at operational level is an important part of business process modeling. The paper gradually utilizes value chain oriented approach to the issue. The results are illustrated on the included figures. Then the basic concepts and relationships of the REA modeling framework are described and illustrated. The REA modeling framework distinguishes between two elementary processes. They are the exchange process, mostly used in the areas of sales and purchases and the conversion process meaning creation of some new materials or goods. The most important part of the paper is a creation of simple enterprise production planning model. The production planning model is based on the resource reservations. That is why the extended REA ontology had to be introduced with commitments and reservations. In the conclusion the main advantages of the REA model approach are emphasized.
