Research On Project Application System Based On Workflow

With the popularity of computers and the advent of the information age,component technology and workflow technology have gradually become research hotspots in the computer field.Component technology solves the drawbacks of system development from scratch.Developers can call the required components from the already established component library according to the specific needs of the system to quickly build the system,which improves the reusability of the software and the efficiency of software development,greatly reduces the cost of software system development,and also Make system maintenance easier.Workflow technology is a core technology of process modeling and management.The concepts such as collaborative office and task flow processing proposed by it can enhance the personal working ability,improve the efficiency of teamwork and accelerate the efficiency of work.Taking the application of scientific research project as an example,applying the idea of component technology to the scientific research project workflow management system is of great significance to improving the operational efficiency and management ability of relevant departments of project application.The main research work of this paper is as follows:Component description and matching: Before performing component retrieval,we must first establish a component library.When components are stored in the library,the facet classification method is mainly used for description.Each component is divided into four main facets,there are several sub-facets under each main facet,and then each sub-facet is divided in detail and represented by keywords,so that the representation of the component is transformed into component keywords set.Then according to the word2 vec method,the component represented by the keyword is converted into a component vector.The components under the sub-facets are clustered by the K-means clustering algorithm based on the maximum and minimum distance.Finally,according to the keywords that users describe the retrieval conditions,they are transformed into retrieval component vectors,and the matching of components is realized by calculating the cosine similarity between the two component vectors of the components.Custom workflow: Integrate the Activiti Modeler into the project declaration system,then encapsulate the Modeler process modeling function,and customize the workflow according to requirements.After defining the workflow,analyze the tasks to be performed by the workflow,and then match the corresponding functional components from the component library.Finally,take the project declaration system as an example.In the system design process,the use of custom workflows shortens the system development cycle and simplifies the subsequent maintenance work.The system architecture is clear and concise.The relevant business logic can be adjusted,added or deleted at any time to improve the system.Flexibility and scalability.And the application of component technology in the workflow system also greatly reduces the cycle of software development and reduces the difficulty of subsequent maintenance.
