Analysis Of Business Process Efficiency Based On Task Assignments

The purpose of the present research is to analyze Business Process (BP) efficiency, which are managed by the Business Process Management System (BPMS). In Business Process Management (BPM) environments, BP efficiency is influenced by task assignment methods. Currently, Dynamic Task Assignment (DTA) method, by which a task is not assigned to a specific user but to a role at build-time, is commonly used for commercial BPMS's. In DTA, the exact user is bound to each task at run-time. On the other hand, Static Task Assignment (STA) assigns task to a specific performer directly when a BP is designed. And to manage role hierarchy in enterprise and overcome the complexity of BP, Role Based Access Control (RBAC) model and Analytic Process Model (APM) are introduced.In order to analyze the BP efficiency of the two types of task assignment, the thesis developed mathematical models for DTA and STA, and select the optimal method of DTA and STA from these task assignment methods through Arena 10.0 and ILOG CPLEX 10.2, which named DHTA and MMW. And then compared the result of the two models by Qualitative and quantitative analysis.The value of the thesis is designed the Dynamic Hybrid Task Assignment model and three STA models, and compare the two typical task assignment methods which selected from these models through comparing. From which proved that the STA is more succinct, independent, easy to control but Narrow Range of Application,weak Flexibility and Failure tolerance, the DTA is more Flexible and wide Range of Application, which is provided assistance to the designer for designing the BPMS.
