Occurrence of equipment failure etc.), that still can not resist natural cause (mud-rock flow, hail, earthquake etc.) or the artificial origin that can not resist
The failure that (attack of terrorism, construction accident, traffic accident etc.) generates.
The statistic algorithm include average algorithm, ask weighted average value-based algorithm, value the method for weighting and linear regression therefore
Hinder prediction technique, specifically:
1, it averages algorithm, calculates the failure rate of every kind of goods and materials of each manufacturer in all valid intervals.Have
Effect section refers to the sections such as the time of user's selection.
2, weighted average value-based algorithm is sought, exponent-weighted average (EMA) is mobile for smoothly inputting, flat by exponential weighting
It moves, it is possible to reduce the influence of historical data excessively remote for present data, i.e., remoter data are to present influence
Minimum, the mobile formula of exponent-weighted average are as follows:
The described a kind of definition mobile for exponent-weighted average of above-mentioned formula, wherein x is scalar input, subscript table
Show i-th of input, the 0th input is to initialize ema0, to iteration update ema value, ema is output valve for subsequent input,
Subscript indicates i-th of output, and decay indicates mobile amplitude, and decay is between 0 and 1, and the value of decay is bigger, for the past
The weight of data is also bigger.Generally, for bigger data are fluctuated, the value of decay is also the bigger the better.
3, it is worth the method for weighting, since the importance of every kind of goods and materials is different, for more important goods and materials, failure rate wishes to get over
It is small better, therefore the average unit price that goods and materials can be used describes importance multiplied by the result of failure rate, at this point, failure rate becomes
At the amount of money of breakdown loss, the risk amount of money can be referred to as, it is assumed that certain goods and materials failure rate of certain manufacturer is q, average unit price
For p, then the risk amount of money is q × p.
4, linear regression prediction algorithm
It is obtained except failure rate except through statistic algorithm, it can also be according to historical failure rate data, to following failure
Rate is predicted, in the case where sample size is less, simple linear regression has good generalization ability, wherein simple
Linear regression formula are as follows:
Wherein,Indicate that the variable of the output of estimation, x indicate the variable vector of input, w is weight vectors, and b is scalar
Indicate biasing.In order to measure the gap between estimated value and true value, need to measure it with loss function, it is assumed that
The x vector of input has n dimension, a shared sample m data, then loss function is.
By derivation, the equation of satisfaction when can be in the hope of the smallest loss:
W=(XTX)-1XTY
Wherein, the matrix form of x and y when X and Y is m sample.
At this point it is possible to weight w be acquired by historical data, so as to predict following failure rate.
