Applying version management of object-oriented database technology in reactive scheduling

The focal points of reactive scheduling are to resolve the impact of emergent and unexpected situations under a time constraint. This study proposes a reactive scheduling architecture based on version management technology of object-oriented database technology. In this architecture, three independent workspaces are used to generate schedule plans while five function managers interact with one another to support version management functions. This study will demonstrate the different types of strategies for reactive scheduling by considering two types of unexpected events: machine breakdown and lack of materials.
