Prosimos: Discovering and Simulating Business Processes with Differentiated Resources.

AbstractProsimos is an open-source tool that discovers business process simulation models from execution data (event logs) and that enables users to perform what-if analysis using the resulting models. Prosimos distinguishes itself from other data-driven business process simulation approaches in the way it models resources. Existing data-driven simulation approaches treat resources as undifferentiated entities, grouped into resource pools, and assume that all resources in a pool have the same performance and availability calendars. In contrast, Prosimos allows resources (within a pool) to have different performance and availability profiles. For example, instead of treating all claims officers in an insurance claims handling process as having the same performance and availability, Prosimos may capture scenarios where senior resources perform some tasks faster than junior ones, or scenarios where some resources work part-time. To this end, Prosimos integrates algorithms for discovering differentiated resource profiles from event logs.
