Research And Development Of Laboratory Information Management System Based On Workflow

With the development of the microbiological testing industry,the form of manual data processing and paper-saving data have been unable to meet the needs of the business development of enterprise laboratories.Not only the information between departments can't be quickly shared,but also customers can't quickly and accurately know the progress of project.Most importantly,the existing distribution methods in workflows make it difficult to achieve reasonable distribution tasks in complex situations.Therefore,this paper designed and developed a set of laboratory information management system based on workflow in combination with the business needs of microbiology testing laboratory.The system relies on modern computer network technology to break the limitations of manual management and existing assignment methods.It can enhance management level,improve work efficiency and accuracy,maintain close communication between enterprises and customers,and enhance the competitiveness of enterprises.The main contents of this paper are as follows:(1)Based on the research of domestic and foreign relevant literature,the existing problems in our country's information management system was summarized,and the main contents of the dissertation was determined.(2)In order to solve the problem that the existing task assignment methods in current workflow can't meet the needs of complicated,complicated and complex testing types,considering the capacity and load factors of task executors.In this paper,we considered the capacity and load factors of the task executor,the task allocation method based on the number of tasks and the algorithm implementation process are proposed.However,due to the fact that the number of tasks does not replace the actual working time,so we used the historical record to predict the task completion time that can be used to measure the workload of the executor.The task allocation based on time balance and the algorithm implementation process are proposed.In fact,there is no historical record of the newly recruited staff.In fact,there is no historical record of new recruits.In this paper,historical records are obtained through the simulation of tasks,and the proficiency of recruits is also improved.(3)In order to test the performance of several algorithms,we compared the standard deviation of load balancing and the total time of completion under different algorithms through simulation experiment,the simulation experiments are used to compare the standard deviation of the load balancing degree and the completion time under different algorithms.The experimental results showed that the time-based task assignment algorithm is significantly better than other algorithms in terms of load balancing and overall work efficiency.(4)The system requirements are analyzed,and the overall structure,the function of each module and the database structure are designed in detail.(5)The system is completed and is tested in many aspects,the test results showed that the various functions are operating normally.Since the system was put into operation,it has run well and has been affirmed by the enterprises.The system can comprehensively manage the laboratory business,improve the efficiency of testing experiments,enhance the communication between enterprise customers,ensure the users to know progress of projects in real time,facilitate the users to quickly obtain sample reports and accurately and efficiently analyze experimental data.
