Workflow system for rearrangement of a workflow according to the progress of a work and its workflow management method

摘要

A workflow system comprises a workflow definition unit, a workflow operation/control unit, and a workflow estimation/prediction unit, the workflow definition unit further includes, as the definition items, rearrangement definition description that is a list of workflow rearrangement algorithms, the workflow estimation/prediction unit further includes a task finish time inquiry unit for examining the finish prediction time of each task, a completion time prediction unit for predicting the completion time of the workflow operation, a definition analytical unit for analyzing the rearrangement definition description, so to supply the analyzed description of rearrangement definition, a rearrangement algorithm library for providing rearrangement algorithms, and a rearrangement unit for, according to the analyzed description of rearrangement definition, taking out a necessary rearrangement algorithm from the rearrangement algorithm library to execute the same.
