Oil and gas pipes project construction operation is a huge engineering, and the various aspects such as time, length, investment, trend of different pipe-line construction are not quite similar.Therefore, objective, just in order to ensure the evaluation result done by oil and gas pipes engineering project to be evaluated, need the second evaluation index factor of the first evaluation index Summing Factor contrast oil and gas pipes engineering project of oil and gas pipes engineering project to be evaluated to carry out sameization process.
Specifically, the factor of impact construction and operation link can be divided into two classes: controllable factor and uncontrollable factor.Sameization process is carried out to the second evaluation index factor of the first evaluation index Summing Factor contrast oil and gas pipes engineering project by oil and gas pipes engineering project to be evaluated, also namely by distinguishing and identifying this two classes factor, the uncontrollable factor affecting oil and gas pipes project operation effect is weeded out, remaining controllable factor, different oil and gas pipes is made to be compare in identical project external condition i.e. " sameization " environment, the comparability of oil and gas pipes project is improved, the result of lateral comparison is more objective, just, the actual conditions of project operation of more fitting.
In actual applications, the controlled evaluation index factor in macroscopic view exactly by people the evaluation index factor variable that can control, constantly can adjust in the process of social change the evaluation index factor.As the term suggests uncontrollable evaluation index factor be namely " people " can not and variable, condition can not be waited by experiment to carry out changing the factor.Then be present in microcosmic point for oil and gas pipes project or oil and gas pipes Project business, the controlled evaluation index factor is exactly the variable that can be taken on a new look by enterprise's self-condition and control.Because enterprise is present in microcosmic point, its existence can be subject to the impact of higher level department or national strategy after all, uncontrollable evaluation index factor of enterprise level then contains some controlled evaluation index factor macroscopically, such as " policy ", " price " etc.
Certainly, it is to be noted: one is that some controlled evaluation index factor macroscopically becomes uncontrollable evaluation index factor in the microcosmic point of enterprise, even if two is that we have marked off the controlled uncontrollable evaluation index factor of evaluation index Summing Factor in microcosmic point, but along with the transformation of national policy or economic situation, some the evaluation index factor may controlled and uncontrollable between occur " conversion ", such as " price ", it is uncontrollable evaluation index factor at present, it is the result of government macro-control, along with deepening continuously of China market process, market will play decisive role, when accounting for leading role in future market, price is possible just forward controlled evaluation index to because of sub-queue by uncontrollable evaluation index factor.
Please refer to table 2, table 2 is the controllability sorted tables of the evaluation index factor that the embodiment of the present invention provides.

Price factor is carried out to the process of sameization process: two are mainly contained to the price index relevant with petroleum gas, one is fixed assets devaluation preparation, one is PPI (petroleum industry price index), cost standardised theory is used to set up the benchmark of across comparison, the price index of nineteen ninety-five is set to 100, wherein convert according to chain rate ratio, derive each year price index, please refer to table 3, table 3 is price index tables that the embodiment of the present invention provides, convert according to the price factor of the price index table shown in table 3 to oil and gas pipes engineering project to be evaluated, namely complete and sameization of this evaluation index factor of price is processed.
Table 3 price index table
Other factors are carried out to the process of sameization process:
By the method for econometrics, find the explanation variable and explained variable, some needs dummy variable.Select suitable sample to carry out regretional analysis, its regression model (being main in linear form) can be:
Y＝α 0+α 1X 1+α 2X 2+α 3X 3+…+u
Y is explained variable, and X is explanatory variable, and u is Disturbance, α 0constant term, α i(i=1,2,3 ...) be regression coefficient.
Certainly, it should be noted that, above-mentioned regression model is an example, the concrete building process of regression model please refer to Fig. 3, Fig. 3 is the process flow diagram of the structure regression model that the embodiment of the present invention provides, and as shown in Figure 3, the building process of regression model can comprise: first, choose variable, variable here comprises explained variable and explanatory variable; Then, regression model is set; Then, carry out model estimation, if model is estimated not pass through, then model is adjusted, reset model; Secondly, if model is estimated to pass through, then carry out model testing, also substitute into by sample data, if model testing is not passed through, then model is re-started and estimate or reset regression model, until model testing is passed through.
When selecting econometric model, be analyze a certain explained variable, finding out the several explanatory variables relevant to explained variable, is the investigation of single index or object, is not the analysis to project entirety.Like this, just need from regression coefficient in the influence factor (explanatory variable rejecting) to single index.
Carry out according to model form returning the regression forms obtaining model:
Y ‾ = α 0 + α 1 X ‾ 1 + α 2 X ‾ 2 + α 3 X ‾ 3 + α 4 X ‾ 4 + · · · + u ‾ ;
Wherein, α i(i=1,2,3 ...) then illustrate relation between Y and X.
As: α 1 = dY dX , Being write as difference form is then: α 1 = dY dX = Y 2 - Y 1 X 2 - X 1
That is: Y 2-Y 1=α 1(X 2-X 1), Y 2=α 1(X 2-X 1)+Y 1
After recurrence then: Y ‾ 2 = α ‾ 1 ( X 2 - X 1 ) + Y 1
Explained variable Y original like this 2just " sameization " is
When next step contrasts, contrast according to the data after " sameization " exactly.
Of course, in specific implementation process, objective and just in order to what ensure the evaluation result done by oil and gas pipes engineering project to be evaluated further, when carrying out across comparison postevaluation to oil and gas pipes engineering project to be evaluated and contrast oil and gas pipes engineering project, the across comparison Post-assessment Method of the oil and gas pipes engineering project that the embodiment of the present invention provides also comprises:
