Computer-implemented methods, computer program products and data processing systems for presenting dynamic data pertaining to a process. In one aspect, region information identifying a plurality of user-selected regions of the process, switching information identifying criteria for switching among the user-selected regions, and dynamic data pertaining to the process, are used to generate a dynamic visual representation of the process which emphasizes, at any given time, only one of the user-selected regions. The user-selected region emphasized at any given time is automatically determined according to the criteria for switching. In another aspect, region information identifying at least one user-selected region of the process and dynamic data pertaining to the process are used to generate a dynamic visual representation of at least a portion of the process containing the at least one user-selected region. The visual representation emphasizes each user-selected region within the context of the portion of the process.

Process data presentation based on process regions

A computer-implemented process for managing configurable resource policies executes a resource expression associated with a received user selection to extract information from an executing simulation. Responsive to a determination that there are no more user selections to process, a set of rules is selected using the user selections and resource expression to populate a resource template using extracted information and selected rules. A resource policy is generated using the populated template. The generated resource policy is applied to the executing simulation, wherein behavior of the executing simulation is modified.

Configurable resource policies

Resource usage calculation for process simulation (such as business process simulation). For each resource used by a simulated process, a usage counter object (or similar data structure) is used. In one embodiment, the usage counter object for each resource includes a list of time slots sorted by start times, and another list of time slots sorted by end times, to keep track of currently-scheduled time slots for this particular resource. In another embodiment, the usage counter object for each resource includes a list of time slots, sorted by start times and having associated end times, to keep track of the currently-scheduled time slots for this particular resource. The usage counter objects also store a count of how many units of this resource are currently in use, and a count of how many users are currently using the resource. These counters are updated using the sorted time slot lists.

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.

Linked decision nodes in a business process model

The illustrative embodiments described herein provide a computer implemented method, apparatus, and computer program product for managing a flow model simulation. In an illustrative embodiment, annotated simulation settings are associated with a source model in response to receiving the source model. The annotated simulation settings are derived from at least one of a set of user-defined simulation settings and default simulation settings. The annotated source model is transformed into an internal domain model using a set of links that are generated using a set of link rules. The set of links maps a set of source model elements to a set of internal domain model elements of the internal domain model. Results from a simulation of the internal domain model are mapped back to the source model to identify a context for the results. Thereafter, a target view model is generated from the internal domain model. The target view model includes the results presented in the context of the source model.

Embodiments of the present invention address deficiencies of the art with respect to modeling a process having a visual representation and provide a method, system and computer program product for importing a visual representation of a process for use in an application. In one embodiment, a computer-implemented visual process model importation method can include identifying an arrangement of one or more visual objects in a visual process model, selecting associations between the visual objects and corresponding representative elements for a target process model, mapping the visual objects in the source model into the selected corresponding representative elements for the target process model, and producing the target process model for the visual process model using the mapping. The method subsequently can include providing the target process model as input to an application such as a simulation engine, a workflow engine or a visual collaboration and documentation system.

Embodiments of the present invention provide a method, system and computer program product for duration estimation of simulating a process model embodied in a directed graph. In an embodiment of the invention, a method for estimating a duration of simulation for a process model embodied in a directed graph can include loading a directed graph for traversal in a simulation engine, identifying nodes in the directed graph, estimating a duration of simulation by the simulation engine for individual ones of the nodes, summing a duration of simulation for the individual ones of the nodes to produce an estimate of a duration of traversal of the directed graph, and presenting the estimate in association with the traversal of the directed graph by the simulation engine.

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.

A computer implemented method and a computer system implementing the method of a business process transformation wizard leads a business analyst through a series of steps to invoke business transformation patterns, in order to analyze the results of those processes. The wizard first prompts the business analyst to specify business objectives of process transformation. Required parameters are added to the business process model guided by the business process transformation wizard until the business process model is completed. Once the model is completed, the wizard prompts the business analyst to select transformation techniques or patterns for optimizing process parameters and, for each selected transformation pattern, optimizes process parameters using a selected optimization technique. The wizard also prompts the business analyst to select transformation patterns for optimizing topology of the business process and, for each selected transformation pattern, optimizes topology for the business process using a selected optimization technique.

The present invention provides a method, system, and program product for modeling processes such as business processes. Specifically, under the present invention, a process having multiple variations is modeled as a placeholder process, and is associated with an annotation that maps the multiple variations to different contexts of the placeholder process. Thereafter, process variations can be generated based on the different contexts of the placeholder process. Integrity checks can also be performed to determine if any of the process variations has an error so that the generation of any corresponding process will be prevented.
