Abstract

A computer-implemented method for managing a worksite is described. The method involves generating event objects comprising event information with respect to the worksite, processing said event objects to generate state objects describing states with respect to the worksite, processing said state objects to generate situation objects defining situations in the worksite; and process said situation objects to generate worksite impact objects estimating impacts on the worksite.
