Research On Schedule And Control Of HY Project Of Group

Information technology is mainly responsible under the railway statistical information system of G Company,which is responsible for information technology project development and management.every year there are a lot of big or small system development project duration is generally up to more than one year.Project in the development process always has this or that kind of problem,and rarely a detailed analysis of a problem.Information technology to undertake projects tend to be on time on the achievement of planned delivery delay for the most part,cargo list marshalling statistical information system development project development cycle is long,also a wide range of aspects,in the information technology is one of the more typical and representative significance project.I first read a lot about IT system development project,information system development project,project management,project progress management,project schedule,project progress control and so on related literature and G group of peers in information technology development projects on the basis of related research,a detailed analysis of freight train marshalling statistical information system development project in the problems that exist in the implementation process,it improves the development schedule of freight train marshalling statistical information system project.The fishbone diagram is used to analyze and classify the factors of the lag of the information system development project.The method of the PERT is used to improve the project duration estimation method.Then,the improvement project network diagram and the key route of the project are determined.The development schedule of the project is improved.Finally,the comparison is made before and after the improvement of the development schedule of the development of the system.Gantt chart and S-curve comparison method are applied to analyze the progress of the project schedule improvement before and after the deviation,and the project was modified according to the plan to meet the basic requirements of the project schedule.A feasibility study about the optimized development plan is also done based on the passenger train information system development which is similar with freight train information system.It is hoped that this paper will provide a theoretical basis for the continuous improvement of information system project planning and control,and also reduce the development cost of similar projects in the future,and provide some experience and reference for future relevant project planning and control.
