Abstract: The present invention relates to a real-time workflow management system with distributed processing applied thereto. As the Internet speed increases and the development of information technology accelerates, a company handles all resource management and decision-making with the workflow management system. However, as the size of user groups, the number of decisions, and the complexity of business processing increase, the overload and system malfunction of the workflow management system increase. To solve this problem, an external connection system is separated, and distributed processing using a plurality of servers is applied to perform smooth workflow management. The distributed processing is applied only to a workflow processing server, so that there is no effect on systems such as electronic payment and ERP which perform external connection. As a load balancing function is applied to a connected server and the distributed processing is applied through the multiple servers, construction time/costs can be minimized. The inconvenience of restarting a task can be resolved through a real-time change function capable of modifying and processing a previously processed task, when the task needs to be changed.
