To be described further each module below.

The index processing module is handled various types of indexs, and polytype index is arranged in the index system, and the processing of dissimilar desired values has specific method separately, and all indexs are divided into Weighted Guidelines in the present invention and non-Weighted Guidelines is handled for two types.

(1) processing of non-weighting class index:

Index system has 56 non-Weighted Guidelines, comprises 29 rate indexs and 27 absolute indexs, and they roughly can be divided three classes: more little good more type index, the type that is the bigger the better index, type index in the reasonable scope.

For more little good more index.For example unusual fortune side rate, invalid interruption duration etc., the processing formula of index is:

(formula 1), min x in the formula _iBe the minimum value in the scope of statistics.

For the index that is the bigger the better.For example cable rate, the average connectivity number of circuit etc., the processing formula of index is:

(formula 2), max x in the formula _iBe the maximum in the scope of statistics.

For the index that should be in the zone of reasonableness, amount etc. when charging construction rate, execution outside the plan for example, the processing formula of index is:

${x^{\&prime;}}_k=\left\{\begin{array}{cc}\frac{M_k-M_{k1}}{U_1-M_{k1}}& (M_{k1}<M_k<U_1)\\ 1& U_1\&le;M_k\&le;U_2\\ \frac{M_{k2}-M_k}{M_{k2}-U_2}& U_2<M_k<M_{k2}\end{array}\right.$ (formula 3)

[U1, U2] is the zone of reasonableness of index in the formula, M _K1And M _K2Be theoretic minimum and maximum.

The processing of (2) weighting class index

There are 16 indexs self not have concrete computing formula in the index system, need obtain by subordinate's index weighted calculation.For example mains supply ability, equipment operation management ability etc., the processing formula of index is:

$x_i^{\&prime;}=\underset{i=1}{\overset{m}{\mathrm{\&Sigma;}}}{w}_i{x}_i$ (formula 4)

X in the formula _iBe the subordinate's desired value after handling, w _iBe the weight of subordinate's index, w _i>=0 (i=1,2,3 ... m), and

For the index after handling, also need estimate, evaluation method is following: evaluation result will compare with desired value and standard value.

(1),, can think that this index has reached the reliability standard requirement when desired value during more than or equal to standard value for the index that is the bigger the better.It is many more that desired value is lower than standard value, and expression should need improved place many more.

(2),, can think that this index has reached the reliability standard requirement when desired value during less than standard value for more little good more index.It is many more that index is higher than standard value, and expression needs improved place many more.

(3), when desired value belongs to reasonable interval, can think that this index has reached the reliability standard requirement for the index that should be in the zone of reasonableness.Index is many more apart from reasonable interval, and expression needs improved place many more.

(4), when calculating desired value more than or equal to standard value after handling through index, can think that this index has reached the reliability standard requirement for subordinate's weighted calculation index.It is many more that desired value is lower than standard value, and expression should need improved place many more.

Index monitoring module index is monitored, wherein:

The become rate index of 0 type of target.Directly " record " that cause molecule event writing system monitored, for example " repetition outage rate ", as long as molecule takes place once, promptly molecule is greater than 0, system proposes to report to the police.The relevant people of being responsible for " repetition outage rate " draws attention, and looks for reason to the next stage of this index: industry expands and electricity power engineering is misfitted; Foundry/electricity power engineering is misfitted; Electricity power engineering is misfitted.Find corresponding director to draw attention according to the next stage reason.

The become rate index of 1 type of target.Require " record " of index of correlation director for all incident writing systems that constitute denominator; For example " scarce completion rate disappears ", " remote control implementation rate ", " engineering zero-fault transfer rate "; And " record " accomplished according to standard marked; If there is not the record of mark, system reported to the police above certain time limit.

Target is tending towards the rate index of zone of reasonableness.Require dynamically recording molecule, denominator, and the parameter true value, true value surpasses the zone of reasonableness of setting, and system carries out the first time and reports to the police; If index surpasses the tolerance interval of setting, system reports to the police for the second time.

In the absolute type index:

Time type.The time type index all requires minimum best, for example permitted hours.The time that each incident is taken place is dynamically included " record " of system in, and " standard max " of setting-up time and " upper limit basically ", if the time of certain incident above " standard max ", system will mark automatically; If surpass " the basic upper limit ", system will report to the police, and require to analyze bad point.

The anomalous event frequency.Target is made as " 0 ", as long as anomalous event takes place, system reports to the police, and requires the responsible person concerned to analyze reason.

Scalar type.For example, amount, actual figure outside the plan etc. when average radius of electricity supply, execution outside the plan." zone of reasonableness " is set as standard, if go beyond the scope, system's mark is also reported to the police.

Index contrast module comprises index vertically contrasted and laterally contrast,

1, index vertically contrasts

(1) rate index

For the index of 0 type that becomes and the index of 1 type that becomes, directly adopt P figure to control.P figure is the control chart of fraction defective in the control chart, and the mean value that can accumulate the P of certain hour comes the centering control line to reach control line up and down, and its relevant formula is formula as follows:

$\mathrm{CL}=\stackrel{\&OverBar;}{P}$

$\mathrm{U\; C\; L}=\stackrel{\&OverBar;}{P}+3\sqrt{\frac{\stackrel{\&OverBar;}{P}(1-\stackrel{\&OverBar;}{P})}{n}}$

$\mathrm{L\; C\; L}=\stackrel{\&OverBar;}{P}-3\sqrt{\frac{\stackrel{\&OverBar;}{P}(1-\stackrel{\&OverBar;}{P})}{n}}$

According to the trend graph P for trend indicators and trends type 0 type 1 indicators, the trend is more down the better, prompting the centerline that is

value can be gradually decreased.When the upper control line that this tendency is touched or surpassed, perhaps there are 7 or continuously greater than 7 ascendant trend, go wrong in the flow process of correspondence with regard to explanation rate index, need in time adjust.

For the rate index of zone of reasonableness type, upper control line can confirm that the control chart that can draw equally carries out trend analysis according to zone of reasonableness with following control line.

(2) absolute type index

Time type or scalar type can be collected continuous basic data, confirm the bound of control chart according to these basic datas.The I-MR that draws then figure is according to the index trend analysis.

2, index laterally contrasts

But the difference master of same index blames people's associated transverse relatively; The difference master of same index is blamed the corresponding desired value ordering of people; Computation of mean values with it as benchmark; If index have " reasonable range " also with it as the datum line of reaching the standard grade; Different according to main duty people on same axle, do block diagram, and identify datum line or the datum line of reaching the standard grade; Each main duty people can see its horizontal status like this, supervises it to improve self work.

Index sensitivity is analyzed and prediction module, according to vertical comparison diagram of index, can carry out sensitivity analysis.

For example, certain index is a1 and a2 in the value of two different times, and the reliability of corresponding these two different times is b1 and b2, and reliability is C to the sensitivity of this index so:

C＝((b2-b1)/b1)/((a2-a1)/a1)

Simultaneously, can probably predict the change degree of reliability according to the absolute type index: suppose that this index rate of change is d, the possible rate of change of reliability is C * d so.

More than combine embodiment that the present invention is described in detail, those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute qualification of the present invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
