Abstract: The present invention generally relates to systems and methods for visual process analysis. The disclosed techniques can include: obtaining a theoretical and an empirical process model, generating a theoretical process layout corresponding to the theoretical process model, where the theoretical process layout is generated using a layout algorithm, generating an empirical process layout corresponding to the empirical process model, where the empirical process layout is generated using the layout algorithm, superposing the empirical process layout onto the theoretical process layout, such that a superposition layout is generated, annotating the superposition layout based on ugliness indicators, such that an annotated superposition layout is generated, and causing the annotated superposition layout to be displayed.

Abstract: The present invention generally relates to systems and methods for checking the conformance of a process behavior against a theoretical process model, and for further providing a detailed diagnostic regarding the process behavior's expectedness and frequency. The provision of this detailed diagnostic includes discovering the empirical models generated by the system's business processes, and matching the defined process model to its corresponding empirical model.

Abstract: Disclosed is a method and system for optimizing a workflow planning via the selection of service providers and data centers according to various QoS (Quality of Service) metrics. The algorithm handles multiple QoS parameters and does not require an a priori weighting of their importance, a typical requirement of other approaches to this problem. This is accomplished by using an algorithm that will guarantee that no alternative solution will be strictly better in all QoS criteria than the chosen solution. A variant of the algorithm to specify the preference order among the QoS parameters is also disclosed.
