Abstract This thesis presents a web-based enactment tool for workflows built using a WIFA tool or a resource-constrained WIFA tool. WIFA is an intutiive yet formal workflow formalism introduced to satisfy the workflow management needs of incident command systems. Resource-constrained WIFA extends WIFA by taking resources into account when modeling and enacting workflows. The existing stand-alone tools developed by WIFA or resource-constrained WIFA are good for workflow editing and verification....
