| With the gradual deepening of China's informatization,the combination of informationization and performance assessment has also entered a new era.The slowness of assessment information transmission and the slow efficiency of performance appraisal have become an obstacle to the current performance appraisal system.The traditional performance appraisal system introduces workflow technology to solve the above problems,but the development of the workflow in the system is achieved through a hard coded process.As the demand changes,the cost of maintaining the traditional performance appraisal system will increase substantially.When a business needs change in many of the company's businesses,system developers need to make significant code changes and system debugging.This will cause system maintenance difficulties.This thesis focuses on the inefficiency of workflow development and code size for traditional hard-coded implementations,requiring developers to change and deploy processes.Through the development of the hospital scientific research performance appraisal system,the Activiti workflow engine is used to achieve soft coding of business processes.For the traditional workflow assessment system,the online process editor is designed in the system for the business staff and developers to communicate with the business process.The process editor is implemented through the AngularJS package oryx.debug.js.The process editor uses the standard BPMN2.0 process modeling language for business process design.Because AngularJS has the characteristics of bidirectional data binding,it can make model data more efficient to modify and save.The model is driven by the PVM process virtual machine in the system.In the PVM,each task node and each node activity of the model is designed as an object,and the flow of the task process is completed through the call between the objects.Through the analysis of requirements,the three-tier structure of the system presentation layer,business logic layer,and data access layer was obtained.This system has also developed a workflow management system module that is open to system administrators for workflow management and maintenance issues,and has implemented an online process designer in the system.Process Designer implements online design of business process models,deployment of business processes,and business process management.Transfer the work originally done by the developer to the system administrator.It solves the problems that the monitoring,deployment and other functions of the traditional workflow need to be maintained by the developers,thereby improving the operating efficiency of the system.The system implements functions such as user management,rights management,log management,process deployment,process design,performance form approval,and performance rating,and meets the basic needs of scientific research performance assessment. |
