Abstract: Embodiments of the present invention address deficiencies of the art in respect to decision node processing in a business process model and provide a method, system and computer program product for linked decision nodes in business process models. In an embodiment of the invention, a business process model simulation method can be provided. The method can include loading a business process model for simulation, designating a decision node in the business process model as a master decision node and linking another decision node in the business process model as a slave decision node to the master decision node. The method further can include simulating the master decision node to select an output pin and storing the selected output pin in association with the master decision node, and applying the selected output pin in the slave decision node when arriving at the slave decision node during the simulation without simulating the slave decision node.

Abstract: An apparatus, method, and computer program product to simulate a business process model wherein a decision node may be modeled using a fair selection process or a random selection process, as selected by an end user. The fair selection process may provide a distribution of invocations among the outgoing paths of a decision node that substantially matches the probabilities assigned to those paths. A fair selection process may do this independent of the number of invocations of the decision node. A random selection process may provide random invocations among the outgoing paths of a decision node according the probabilities assigned to those paths.
