Abstract
A workflow generated from a declarative model of a real world process represents the procedural steps to accomplish the process. In one embodiment, the declarative model may include a first number of state nodes and a second number of task nodes interconnected with the state nodes. In such cases, generating a workflow may be accomplished by choosing one of a number of paths through the model, each of the paths comprising an alternating series of one or more of the state nodes and one or more of the task nodes with any predecessor state node in one of the paths representing a precondition for a subsequent task node along the one of the paths and any following state node of the subsequent task node along the one of the paths representing a result of applying one or more actions that correspond to that task node. As part of a computer assisted scheduling system, the model may be configured to receive updates reflecting changes in the real-world manufacturing environment. Such changes may represent completed tasks, and/or a change in the availability of one or more resources represented in the model.
