Design And Implementation Of Workflow In The Network Sharing Platform Of Near-infrared Analysis

The technology of workflow is the key technology for the process automation, and it has become the most one of the essential component in enterprise informationization construction.It plays an very important role in the field of improving enterprise management efficiency,optimizing and adjusting the business process of the enterprise.Some processes of the network sharing platform of near-infrared analysis has the typical characteristics of the business process, such as the collection,processing,detection,transmission,upload,storage and release of the imformation. In order to complete these process,a lots of professional staff and managers need to cooperate with each other,and during this procedure,some problem would come up inevitable,so, all of the revevant people must coordinate to resolve these problems over and over,Then,the time of mission completed was increased,the efficiency of the task execution was decreased.Thus, To achieve optimize enterprise structure and improve the efficiency of the processes execution,it is necessary to take workflow technology into the platform,and design a function module with task control,task management and task monitor for the platform.and because of this,the platform structure was become more clearly,the respond to the changes of business processes was more rapidly.This paper focused on the analysis of the Activiti workflow engine,such as system architecture,functional service components,etc.and apply it to the network sharing platform of near-infrared analysis. But we found that the Activiti workflow engine can not meet the requirement of the network sharing platform of near-infrared analysis in the aspect of task control completely,like process jump.then,In order to meet the requirement of the platform mostly,we present an algorithm of the task execution priority,and create a tree of the task execution priority for every business process,and record all of information of the task execution, strengthen the function of workflow engine,which can minitor the process execution dynamicly, trace the node which was executing,adjust and intervene the state of task execution artificial,also provide statistical information and optimization information of the process,and save the whole log,realize the cancle and rollback of process task correctly.The module of workflow which was designed and implemented by taking Struts,Spring,Hiberate,Activiti which are open source components in this paper,that was proved run well in the network sharing platform of near-infared analysis,the result of the system testing showed that the system was stable and efficiency,especially,the workflow module can meet the requirement of the flexible jump of the collection and detection task.
