Research On Model And Methodology For Mutil-Factor Performance Assesment Of Project Management

In order to achieve project multi-factors performance evaluation, constructed aproject performance evaluation model of multi-factors, realized the analysis forproject performance of multi-factors, and enhanced the scientificalness,systematization and accuracy of project performance analysis. In addition, we madespecific analysis in terms of different types of projects for the constraints of cost,time and scope, and put forward a set of more scientific and effective performancemeasurement methods.Research project earned value management theory based on literatures, in-depthanalysis of the problems of the existing Earned Value Management in terms of cost,time, and other factors. The analysis results show that, there are two main reasons forresulting in the existing shortcomings and deficiencies of earned value managementapproach for two main reasons. First of all, the developers and users admit thatsimplifying multi-factor performance of the project into the performance of the twoelements of cost and time. resulting in not be able to understand and master the otherelements of the project performance through the existing earned Value Management;the second is unable to clearly distinguish the relationship between the factorsthrough using the existing earned value method because of the inadequate researchabout the relationship between project factors, which leads to a lack of basic supportin the process of integrated evaluation of the project multi-factor performance.Based on drawing on the existing earned value management principle andin-depth analysis of the relationship between factors, the author introduced statisticalmulti-factors index method, improved and developed the existing project earnedvalue method, and constructed the performance evaluation model for projectmulti-factors, achieved the integration analysis for project cost, schedule, scope andprice. In the aspect of cost, the author has done the research on the characteristics ofcost-constrained projects and the key factors which affect this kind of project, anddivided these key factors into controllable factors and uncontrollable factors. The comprehensive cost deviation index equation is built through using the performanceindex of project performance evaluation of multi-factors, and established a balancedand harmonious relationship between the multi-factors. In the aspect of time element,this dissertation analyzed the characteristics of the time-constrained project, anddivided project into scope determined time-constrained project and scopeundetermined time-constrained project. Using project multi-factors performanceevaluation model to analyze time-constrained project, thus identify the timeperformance deviation which caused by scope change. In the aspect of scope element,this dissertation provided scope evaluation method. Based on the specific conditionsof project resources configuration relationship, set up four basic variables, such asresource planning usage, resource actual usage, planning usage proportion ofresource, actual usage proportion of resource, and also set up a intermediatevariables of actual amount of resource investment. Through considering therelationship between variables, we can measure the performance level of projectscope effectively.The main innovation points of this dissertation are as follows:Firstly, the author has done the research and constructed the projectmulti-factors performance evaluation model. This dissertation based on projectearned value management theory and method, and introduced intermediate variableto analyze performance deviation, revealed the basic principle of two factors indexanalysis method in its application of social statistics index system. And throughusing statistics multi-factors index analysis and the coupling of priority sequence ofproject factor step by step integration, constructed the evaluation model of projectmulti-factors, avoided analyzing factor from single factor perspective, hence we cananalyze performance from two angels of parsing and geometric. The construction ofthis model for the Earned Value Management System in an existing project on thebasis of intuitive and effective to carry out the project multi-factors performanceanalysis opened up the idea.Secondly, the author has done the research and constructed the performanceevaluation model for cost-constrained project. This dissertation analyzed the basiccharacteristics of cost-constrained project and the key factors which affect performance, and carry out cost estimate and management strategies analysisthrough using project multi-factors performance evaluation model. Then, the authordivided cost management elements into controllable influencing factors anduncontrollable influencing factors, through integrating controllable elements ofscope, schedule and cost, constructed the controllable elements comprehensive costdeviation index equation, and thus put forward through using controllable elementscomprehensive cost deviation index equation to geometric proportion control projectelements costs and implement management strategy of critical control point based onthe priority sequence.Thirdly, the author has done the research and constructed the performanceevaluation model for time-constrained project. In this thesis, the author used earnedvalue time method based on project key path to analyze the performance of scopedetermined and scope undetermined, facing unspecified discussing scopeundetermined project of the existing project earned value method, using projectmulti-factors performance evaluation model to separate schedule deviation whichcaused by scope change, making project schedule performance analysis moreaccurate.Fourthly, the author has done the research and constructed the performanceevaluation model for scope-sonstrained project. Some basic variables were designedin this thesis, such as the Resources Ration for Schedul, the Resources Ratio forActual Performace and the Actual Resources Under Schedule Ratio, the variable ofthe Actual Resources Under Schedule Ratio which constituted the concept of projectscope earned value. We can measure project scope performance deviation effectivelythrough using project scope earned value, not only can meet the cross-computingneeds of scope indicators, cost indicators and schedule indicators, and also canachieve a good convergence with the traditional earned value management method,and can eliminate uncontrollable factors and measure project scope performancemore accurate through using configuration ratio to analyze deviation.
