Description

Method and device for setting buffering threshold for accounting

Technical Field

The present disclosure relates to the internet field, and in particular, to a method and an apparatus for setting a buffer threshold for billing.

Background

In the process of processing accounting for a financial account, either transferring funds out of the account or transferring funds into the account requires accounting. The accounting processing process mainly comprises two parts, namely transaction detail recording and balance updating. Common billing methods include buffered billing and real-time billing.

The buffering accounting refers to accumulating transaction details in the accounting request, and then updating the balance (for example, updating the balance once per minute) according to the accumulated transaction details in a uniform time period. And the real-time accounting refers to accounting processing of the accounting request in real time.

The accounting service for transferring funds from one account belongs to a fund flow-out type accounting service, and the corresponding account can also be called a flow-out type account. Currently, for the fund flow-out service, a billing mode switching threshold value needs to be set. Specifically, when the balance of the account is greater than the threshold, it is indicated that the balance of the account is sufficient, and a buffered accounting mode may be selected for accounting, and when the balance is less than the threshold, it is indicated that the balance is at risk of overdraft, and a real-time accounting mode needs to be selected for accounting. However, a threshold setting that is too high may result in some outbound billing services failing in real time, and a threshold setting that is too low may risk an outbound account being overdrawn.

In processing accounts for a financial account, either transferring funds out of the account or transferring funds into the account requires accounting. The accounting processing process mainly comprises two parts, namely recording transaction details and updating balance. Common billing methods include buffered billing and real-time billing.

The buffering accounting refers to accumulating the transaction details in the accounting request, and then uniformly updating the balance according to the accumulated transaction details in a fixed time. And the real-time accounting refers to accounting processing of the accounting request in real time.

In view of the above problems, embodiments of the present specification provide a method for setting a buffering threshold for accounting, and a device for setting a buffering threshold for accounting, which is used for executing the method.

The following is a detailed description of the buffering threshold setting method for accounting according to this embodiment, and referring to fig. 1, the method may include the following steps:

s101, determining at least one buffer threshold influence factor of a period to be set from a factor set;

the buffering threshold value is the lowest critical value for enabling the buffering accounting mode to take effect, when the balance of the hotspot account is larger than the buffering threshold value, the account balance is sufficient, the buffering accounting mode can be selected for accounting, and when the balance is smaller than the buffering threshold value, the balance is at risk of being overdrawn, and the real-time accounting mode needs to be selected for accounting.

The buffer threshold impact factor is a predefined traffic element that affects the buffer threshold. The factor set may be a set of elements of multiple dimensions, and these elements affecting the buffer threshold may also be referred to as buffer threshold impact factors, and a user may set a required buffer threshold impact factor in the factor set according to different application scenarios. The following illustrates factors and possible dimensions and buffer threshold impact factors that the corresponding dimensions have:

basic factor dimension: the basic elements influencing the threshold analysis in the common accounting system are mainly summarized and collected, and the basic elements mainly comprise the accounting date end balance of an account, and the amount of funds flowing in, the amount of money flowing out and the like in unit time.

The periodicity factor dimension: the method mainly covers the elements of common statistical period dimensions, such as expressing data by time, day, week, month and the like.

Scene factor dimension: the set of business elements that affect the threshold change of an account, such as whether there is a repayment date, whether there is a marketing campaign, overdue rate, etc., is mainly covered.

Guest group factor dimension: the factor of the participant influencing the threshold value change of a certain account is mainly covered, and the type of the participant is mainly expressed, such as a guest group is an individual, an enterprise, a same industry and the like. In the process of carrying out concrete analysis, the actual system business scene can be combined to carry out finer-grained division, for example, an enterprise customer group can be divided into industry information engaged in by the enterprise, and the like.

The factor set is a set of predefined buffer threshold influence factors, and in practical application, a plurality of buffer threshold influence factors of each dimension influencing fund change of an account in a certain period need to be analyzed, and an acceptable account buffer threshold in a unit period to be set is determined according to the buffer threshold.

Wherein, the predefined factor combination of different dimensions can be expressed as follows:

selecting a basic factor set f1= { a1, a2, a3, a4}, wherein the basic factor set f1= { fund inflow stroke number, fund inflow amount, fund outflow stroke number, fund outflow amount };

selecting a period factor set f2= { t1, t2, t3}, which means that the period factor set f2= { timekeeping, day counting, week counting };

selecting a scene factor set f3= { s1, s2}, which means that the scene factor set f3= { repayment date, marketing activity };

the guest group factor set f4= { p1, p2, p3}, which means that the guest group factor set f4= { personal, business, industry }.

And analyzing based on the service scene of the period to be set, and selecting a buffering threshold influence factor set of the period to be set from the factor sets of the dimensions, wherein if the buffering threshold influence factor set F = { s1, t1, a1, a2, a4, p3} of the period to be set is selected, the set F represents that the buffering threshold influence factor set F = { repayment date, timekeeping, number of funds inflowing strokes, amount of funds inflowing, amount of funds outflowing amount, same industry }, of the period to be set.

S102, determining a buffer threshold influence factor of at least one history period;

determining a buffer threshold impact factor for the historical period from the existing historical transaction data. To get more samples, multiple history periods may be extracted and the buffer threshold impact factors for these history periods may be obtained separately.

In general, the period length of the history period and the period to be set should be consistent, for example, if the period to be set is the first week of the next month, the history period may be selected as the first week of at least one history month, or the history period may be selected as the previous weeks of the period to be set, etc.

S103, calculating the buffer threshold value influence factor of the historical period by using a preset algorithm, and calculating the factor similarity of the buffer threshold value influence factor of the historical period and the buffer threshold value influence factor of the period to be set;

and calculating factor similarity, namely determining the factor similarity of the historical period and the period to be set, and if the condition factors in the factor combination range influencing the threshold value are similar or similar in the historical period and the period to be set, obtaining a reasonable target threshold value set of the period to be set according to the existing buffer threshold value of the historical period.

For example, the factor similarity may be calculated from different dimensions, taking the dimension as a service scene as an example, the scene factors of the historical period are combined into { no marketing activity, no customer repayment date, and 0.12 of the historical period, the scene factors of the period to be set are combined into { no marketing activity, no customer repayment date, and 0.11 of the historical period }, and the comparison result of the two is that no marketing activity exists in the period, no customer repayment date exists in the period, and the historical period is similar, and it can be known from the comparison result that the factor similarity in the dimension of the customer base is higher in the two periods.

S104, determine whether the factor similarity is higher than a preset threshold? If the factor similarity is higher than the preset threshold, executing step S105, and if the factor similarity is not higher than the preset threshold, not operating;

and S105, determining the corresponding historical period as a sampling period, and determining target thresholds of different time points of the period to be set according to the buffer thresholds of different time points of the sampling period.

If the factor similarity between the historical period and the period to be set is higher than the preset threshold, the historical period can be used as a sampling period for predicting a target threshold of the period to be set, and then the target thresholds of different time points of the period to be set are determined according to the buffer thresholds of the different time points of the sampling period. And if the factor similarity between the historical period and the period to be set is not higher than a preset threshold, indicating that the historical period cannot be used as a sampling period for predicting a target threshold of the period to be set, and discarding the historical period.

Further, the buffer threshold data of different time points of the sampling period can be determined according to the inflow amount and the outflow amount of the sampling period at each time point in the account historical transaction data, the optimal buffer threshold to be set at each time point of the sampling period is determined according to the actual service amount, and the optimal buffer threshold is determined as the sampling threshold used for predicting the period threshold to be set.

After the corresponding history period is determined as the sampling period, referring to fig. 2, the specific steps of determining the target threshold values at different time points of the period to be set according to the buffer threshold values at different time points of the sampling period are as follows:

s201, generating a corresponding sampling threshold curve according to the buffer thresholds at different time points of the sampling period;

s202, extracting discrete points of the wave crest and the wave trough of the sampling threshold curve, and connecting the discrete points to obtain a reference threshold curve.

S203, carrying out deviation calculation on the reference threshold value curve according to a predefined reference deviation amount, and determining a target threshold value curve corresponding to the period to be set according to the calculation result, wherein the target threshold value curve comprises a set of target threshold values at different time points of the period to be set.

The curves in this embodiment can be seen in particular in fig. 3 and 4.

Fig. 3 includes a corresponding sampling threshold curve L1 generated according to the buffer thresholds at different time points in the sampling period, and a reference threshold curve L1' obtained by connecting discrete points after extracting the discrete points of the peak and the trough of the sampling threshold curve.

Since the sampling threshold values at a plurality of time points of the sampling period (history period) can be directly derived from the known inflow/outflow amount of the history transaction data for the period, the corresponding sampling threshold value curve L1 can be directly generated from the acquired plurality of sampling threshold values. After a sampling threshold curve is determined, discrete points of the wave crest and the wave trough of the sampling threshold curve are taken, and then the discrete points are connected to obtain a reference threshold curve describing the basic trend of the sampling threshold curve.

As shown in fig. 4, fig. 4 includes the reference threshold value curve L1 'obtained as described above and the target threshold value curve L2 obtained by performing offset calculation on the reference threshold value curve L1'. The offset calculation usually needs to introduce an offset amount, and the offset amount is introduced to obtain a more accurate target threshold curve of the period to be set. The offset calculation can generally be set to offset the target threshold curve upward to leave some margin to avoid the risk of an account being overdrawn. By way of example: the threshold value set of different time points in the reference threshold value curve L1' is [10,20 ], the offset is calculated to be adjusted up by 10%, and after the offset calculation, the calculation results [11,22 ] are the target threshold value set.

Further, after the period to be set is ended, the reference offset may be corrected according to the actual service data of the period to be set.

Further, a plurality of historical periods with factor similarity higher than a preset threshold with the period to be set can be determined as sampling periods, and the target threshold of the period to be set can be predicted according to the plurality of sampling periods.

Specifically, after a plurality of different sampling periods are determined, the buffer threshold values at the same time interval point are extracted in different sampling periods, the maximum buffer threshold value at each time point is determined as the sampling threshold value, and a sampling threshold value curve is generated according to each sampling threshold value.

For example, the following steps are carried out: determining two history periods with similarity higher than a preset threshold value with a period factor to be set as a sampling period, determining that each set of buffer threshold points of the two sampling periods is s1= {100,50,112,30}, and s2= {90,48,120,28}, respectively, according to a sampling threshold curve, taking the maximum value of the buffer threshold values of the same time point in the two sets, namely, taking 100 in s1, 50 in s1, 120 in s2, and 30 in s1 as sampling thresholds, respectively, and performing offset calculation on the sampling threshold of each point to obtain a final target threshold value of the period to be set, taking 0.1 as an example in the case of an offset amount, and taking s3= {110,55,132,33}, respectively.
