Research On Modeling And System Of Intelligent Decision-making Process For Aquaculture Based On Workflow And Rule Engine

In recent years,the popularization of mechanical equipment in aquaculture has realized mechanized operation in some aquaculture links,such as oxygenation and bait feeding.With the rapid development of information technology,the level of intelligent management of aquaculture has been improved,the industrial structure reconstructed and optimized,and partial aquaculture has realized intelligent and informationalized management.However,the existing information management platforms for aquaculture are lack of scientific and effective process management and guidance,which make the aquaculture operation much complicated.Moreover,traditional aquaculture personnel have low acceptance of the new systems and still need to rely on experience judgement and manual operation control.Therefore,there still exist many problems in aquaculture,such as unclear farming business rules,high error rate,low decision-making efficiency and error-prone.In addition,current researches on aquaculture processes tend to focus on single factor,such as environmental monitoring on water quality,feeding equipment developing,disease prediction,etc.And there is rare research on aquaculture business processes and intelligent decision-making.Based on the situation,this paper designs and develops a set of aquaculture monitoring system which can conduct process management and intelligent decision-making using workflow technology and rule engine technology.It can provide more professional information-based aquaculture process guidance and standardize the information management of aquaculture process for relevant personnel.At the same time,it can clarify the business rules of aquaculture,improve the efficiency of decision-making and provide aquacultural experience for personnel.To summarize,this paper carries out the following research:Firstly,a combined management mechanism of workflow and rule engine is proposed.It analyzes and summarizes that the aquaculture business process has the characteristics of cumbersome and unclear steps,timeliness,circulation,concurrency and a large number of aquacultural business decisions.According to these characteristics,integrated with the respective principles and functions of workflow engine and rules engine,a combined management mechanism of workflow and rule engine suitable for aquaculture is proposed,and the operational principle of two-way driving between them is described in detail.Secondly,a modeling solution aiming at realizing intelligent decision-making process for aquaculture is proposed.According to the characteristics of aquaculture process and the abovementioned combined management mechanism,the special workflow patterns in aquacultural process are extracted,such as task rollback,cycle,asynchronous concurrency,timely prompting and selection.Further,the Activiti solutions of these patterns are formulated.This study puts forward a method of using rule engine to drive process causing condition transfer to execute business rule decision.And on this basis,a flexible workflow modeling method with rules is formulated to make the steps of modeling more agile.Thirdly,a process management model of intelligent decision-making for aquaculture is constructed.Taking Penaeus vannamei as the research object,the various stages of its breeding business process are analyzed to lay a foundation for modeling.According to the key technology solutions of aquaculture process,Activiti workflow engine plug-in and Drools rule engine plug-in are incorporated simultaneously in Eclipse integrated development environment.Then,the workflow model of Penaeus vannamei breeding process is built by Activiti workflow designer,the function of each node in the model is described in detail,and the abnormal control method of asynchronous concurrent process in the model is given.Through Drools rule engine,the analysis,definition,design,writing and triggering of the breeding business rules are established.Finally,all the processes and rules of the model are tested.The test results have demonstrated that the model can provide scientific and professional process guidance and efficient business decision-making management for aquacultural process.Finally,a process management system of intelligent decision-making for aquaculture is designed.On the basis of the above research findings,this paper completed the framework and function designing of the intelligent decision-making process management system for aquaculture based on the SSH framework.The main functions of the system are realized,including aquacultural workflow deployment management,aquaculture process execution,rule decision-making management and aquacultural rule management,which provides a professional and scientific guidance tool for aquaculture process supervision.In conclusion,through the combination of workflow and rule engine in aquaculture process management,the process management model and system of intelligent decision-making for aquaculture are developed,which provide a feasible new method for the field of intelligent process management of aquaculture and are of great significance for promoting the development of modern aquaculture industry.
