1. An apparatus comprising: at least one processing platform comprising at least one processing device having a processor coupled to a memory, wherein the processing platform implements a plurality of modules for integration of dynamic recognition of complex events with case-based processing, the modules comprising: a complex event processing module; a case-based processing module coupled to the complex event processing module; and a proactive risk assessment and forecasting module coupled to at least one of the complex event processing module and the case-based processing module; wherein complex event recognition in the complex event processing module triggers one or more case-based activities in the case-based processing module; wherein a given complex event comprises one or more component events, the one or more case-based activities triggered for the given complex event being based at least in part on an analysis of arrival and non-arrival of the one or more component events associated with the given complex event; and wherein the proactive risk assessment and forecasting module generates one or more alerts based on process metadata of the case-based processing module.
