Research On Schedule Planning Of S Company Vehicle Glass Tempering Furnace Project

With the progress of present age and the development of science and technology,Customer and market requirements for project delivery are increasing.In order to adapt to these new requirements,enterprises also require more and more accurate control of the project schedule.There are many problems in the traditional critical path method when managing project progress,Dr.Goldratt proposed Critical Chain Project Management method,which proposed new ideas for resource-constrained project schedule planning,which can effectively shorten the construction period,improve project execution efficiency,and save project time cost.This paper studies the problems of project schedule planning in work,Mainly for the unreasonable project planning and other problems.First,in order to avoid project delays due to mistake planning,it is common to increase the safety time for each task to offset the risk of delays.This causes redundancy in the entire project duration,which is disconnected from the actual duration,and the project duration is increased to increase project costs It also reduces customer satisfaction.Second,there is no good action plan when there are delays in the project process.There is no emergency plan for the bottleneck tasks.When there is a conflict between tasks,there will be effect the project planning.By researching these two issues,the aim is improving the reliability of the project delivery cycle,increasing the control of the project and find a simple and effective way of project planning.This paper solves the problem of resource conflicts and path slacks in a large-scale equipment manufacturing project by using Critical Chain Project Management method.By Using Microsoft Project software to compile project plans based on critical path theory,automatically generating Gantt charts and critical paths,make project planning clear and standardized,adjust resource conflicts based on critical path plans,and make plans meet actual resource constraints.Then use Critical Chain method to optimize the project schedule,collect the project uncertainty evaluation index,use the TOPSIS method to process the evaluation index,and obtain the uncertainty coefficient of each process.Calculate the safety time and the project buffer.In terms of control progress,the project buffer is proportionally distributed to each process,which improves the monitoring sensitivity.This paper optimizes the progress of large-scale equipment manufacturing projects and provides a reference template for manufacturing projects with complex structures,processes,and long cycle.By applying the critical chain method to the practice of equipment procurement projects,good results have been achieved.The enlightenment for subsequent projects is that using the critical chain method to manage project progress can effectively solve the problem of slack paths and shorten the construction period,then save costs and improve economic benefits.The preparation of the schedule is forward-looking.By using the critical chain method to compile the project plan,the project manager can clearly determine the bottleneck resources and key tasks of the project,then improve management efficiency.By distinguishing critical chains from non-critical chains,project managers can focus more on the management of critical chains and project buffers.Safety time and buffer calculations are more scientific,rational,and objective.When calculating task safety time and buffer size,when determining uncertain factors that affect project progress,consider both factors that are based on link characteristics and the influencing factors of project characteristics make the evaluation system more comprehensive and accurate,and closer to the actual situation.It has a good reference significance for small and medium-sized manufacturing companies to optimize the project schedule of key chain technologies at a lower cost.
