For example, an electronic file store inventory can be a relational database file . A task can either retrieve or update a file store. They are represented by a set of actors, A. To represent resource management, actors are classified into different roles, R . R 2 A is designed to captured the skill sets of actors. To analyze performance issues such as throughput and utilization, time elements are attached to places, tasks, and servers.
Time attached to places represents the delivery time from one task to the next.
Time elements attached to servers identify service rates and priority assignments among tasks. Analysis of a DFM Representation DFM clearly identifies document manipulation and circulation in an organization. Evaluate document management options For a given workflow system, let r be the ratio of document processing and distribution time over total task time. The efficiency of document management is hence a decreasing function of r. Evaluate workflow design options DFM has an added advantage of offering mathematical analysis for document flow design.
