Research Of Plan Management About Engine Development Project Of G Company

At present,China has become the largest new car market in the world.With the increasing domestic market,the country attaches more and more importance to environmental protection,and the regulations are more and more strict on fuel consumption,emissions and other requirements,and vigorously develop new energy vehicles.In the market environment of fierce competition,if the development products of traditional power want to occupy the existing market,it is necessary to shorten the development cycle and strictly control the schedule.For the engine development project,due to its high technical complexity,once there are major problems in the development process,it is likely to lead to project delay.Therefore,how to prevent major quality problems in the project development process and how to solve them quickly and effectively becomes the key to project management.First of all,this paper studies and analyzes the current situation of engine development project schedule delay in G company,and makes clear the stages of project schedule delay.In the process of analysis,firstly,WBS decomposition is carried out for the design verification stage which is generally delayed,and the critical path and the work package which is delayed in the critical path are found out in the projects with serious delay.Subsequently,for the delayed work package,further reason analysis is carried out to clarify the problem points of the project process and quality problem decision-making.First of all,this paper classifies the quality problems into four levels: L1 to L4 according to the length of solving time.Through the correlation analysis of the number of delayed months of work package with the quantity of L4 level key problems and the cumulative solving time of L4 level key problems,it is found that the more L4 level key problems are,the more likely the work package will be delayed,and there is a positive correlation between the cumulative solving time of L4 level key problems and the work package delay time.For this feature,on the one hand,it analyzes the causes of the design process through the axiomatic design theory to find out the reasons which are the unreasonable design process of the system and parts and the lack of control in the process of the supplier's process design;on the other hand,the research group finds that the long time to solve the L4 level key quality problems was caused by many ineffective countermeasures,and the root cause was that the influencing factors were not identified in the process of problem solving and the problem decision authority allocation was unreasonable.In view of the root cause of the above analysis,this paper aims to prevent the occurrence of L4 level key problems by optimizing the design process and establishing the supplier process design management process.In addition,by establishing the process and method to identify the influencing factors of key parts,adding single part verification before verification and optimizing the decision authority of key problems,the purpose of shortening the time of solving key problems is achieved.Finally,the regression equation between the number of work package delay months and the cumulative solving time of L4 level key problems is obtained by using regression analysis method,and the optimization effect of various measures on the project schedule is predicted.On the one hand,each measure can reduce the quantity of key problems,on the other hand,it can also shorten the cumulative solving time of key problems.Through this equation,it can be predicted and found that the number of months of development cycle delay of the original G company engine project can be effectively reduced after optimization.
