JPH0374790A - Fuzzy controller for medium supply of automatic transaction machine - Google Patents

Abstract

PURPOSE:To control the supply of media with high efficiency and in response to the transaction situation by outputting the most appropriate correction value out of a fuzzy rule storing the proper number of remaining media and the correction value of a specific data period and applying the fuzzy inference control to a discharging amount limiting means and a small remaining amount informing means. CONSTITUTION:When a small remaining note sensor S detects a small number of remaining media stored in an automatic transaction machine in its transaction process, a fuzzy inference control means 25 outputs the most proper supply correction value based on a fuzzy rule in order to obtain an optimum consequent part with the detection element of the sensor S defined as an antecedent part. Then the fuzzy inference control is applied to a discharging amount control means 23 and the sensor S with output of the supply correction value so that a discharge amount of the automatic transaction machine is controlled and a clerk in charge supplies the media. As a result, a discharge amount of the automatic transaction machine is limited by such an extent that causes no down of the machine when the number of remaining media of the machine is decreased. At the same time, an instruction is given to the clerk to supply the media for prevention of shortage of media. Thus it is possible to always maintain the working of an automatic transaction machine having the high control ability.

Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to automatic transaction machines for deposit and withdrawal processing, such as those used in banking, and more specifically to automatic transaction machines that handle media such as banknotes, coins, and slips. The present invention relates to a media replenishment fuzzy control device for an automatic transaction machine that efficiently manages replenishment.

(b) Conventional technology In general, this type of automatic transaction machine is capable of depositing, withdrawing, transferring money,
It has various transaction functions such as passbook entry and balance inquiry, and customers select one of these functions to execute automatic transactions.

By the way, in certain time zones such as certain time zones and days of the week, there is a tendency for withdrawal transactions to be concentrated, resulting in a shortage of banknotes, for example.

Therefore, the staff predicts the amount of replenishment in advance and replenishes it sufficiently during specific days and times when usage frequency increases, but the estimated amount of replenishment is inaccurate, such as the amount released from each automatic transaction machine varies greatly. Another problem was that the automatic transaction machines were often down, reducing the operating rate.

(C) Problems to be Solved by the Invention The present invention aims to provide a fuzzy media replenishment control device for an automatic transaction machine that is capable of efficiently managing replenishment according to the transaction status of the automatic transaction machine and has high replenishment management performance. purpose.

(d) Means for Solving Problems This invention provides a discharge amount limiting means for limiting the amount of media stored in an automatic transaction machine and a remaining amount of media stored in a media storage section. a detection means for detecting the remaining amount of media in the automatic transaction machine and a specific date and time when the frequency of use of the automatic transaction machine is temporarily concentrated; In response to the input of the media remaining amount and the specific date and time period of the automatic transaction machine, the most appropriate correction amount is output from the fuzzy rule containing the appropriate media remaining amount and correction amount for the specific date and time period, and the above-mentioned release amount limiting means and This is a medium replenishment fuzzy control device for an automatic transaction machine, which is equipped with a fuzzy inference control means that performs fuzzy inference control of a remaining quantity notification means.

(e) Effect of the Invention According to this invention, during the transaction process of an automatic transaction machine, when the detection means detects the remaining amount of media stored in the automatic transaction machine, fuzzy inference is performed using this detection element as an antecedent part. The control means outputs the most appropriate replenishment correction amount based on fuzzy rules in order to find the optimal consequent, and uses this output to limit the amount of one discharge from the automatic transaction machine, and also allows the clerk to replenish the medium. The emission amount limiting means and the remaining amount detecting means are controlled by fuzzy inference so as to achieve the following.

(f) Effects of the invention For this reason, when the amount of media in automatic transaction machines tends to be low,
It is used as an automatic transaction machine with high management ability to always keep the automatic transaction machine in operation by limiting the amount released at one time to the extent that the automatic transaction machine does not go down and notifying the staff to replenish the medium to eliminate media shortages. be able to.

(g) Examples An embodiment of the present invention will be described in detail below based on the drawings.

The drawing shows a banknote replenishment fuzzy control device for an automatic transaction machine,
This automated teller machine 11 has a CRT 12 that also serves as a touch panel for displaying and guiding customers through transaction operations, a speaker 13 that provides voice guidance for transaction operations, a bankbook insertion slot 14, a bill slot 15, and a coin slot. 16, a card insertion slot 17, a handling display 18, and a call button 19 for the customer to call an attendant, allowing transactions such as deposits, withdrawals, transfers, bankbook entries, and balance inquiries.

Figure 2 shows the fuzzy inference control circuit when replenishing banknotes, and C
The PU 21 controls the payout number limiting device 23 and the remaining amount alarm according to a detection signal inputted from a banknote remaining amount detection sensor S that detects the remaining amount of banknotes and a specific date and time when customers intensively use the banknotes, and a program stored in the ROM 22. The device 24 is caused to output the remaining amount control operation via the fuzzy inference engine (hereinafter referred to as FIE) 25, and the necessary control data at this time is stored in the RAM 26.

The above-mentioned FIE 25 converts the current detection element determined by the detection signal from the automatic transaction machine 11 into antecedent parts X1-X3 (
Condition part), and the replenishment operation set corresponding to this current detection element is the consequent part Yl.

A fuzzy rule is set as Y2 (conclusion part), and the most appropriate replenishment processing operations Zl and Z2 are output based on the fuzzy rule from the above-mentioned detection elements, and these outputs Z1.
At Z2, the number-of-dispensing device 23 and the remaining amount informing device 24 are controlled by fuzzy reasoning so that the current number of bills dispensed by the automatic transaction machine 11 is limited and the clerk replenishes a predetermined amount of bills.

The above-mentioned fuzzy rule is set according to a predetermined fuzzy rule table 27, and this is based on the amount xl of banknotes remaining in the automatic transaction machine 11,
The appropriate values corresponding to the usage level x2 by day of the week and the usage level x3 by hour are determined in advance, and by comparing these appropriate values with the detected facts, the most reasonable conclusion for these facts is drawn. It is set by membership functions using fuzzy variables as shown in FIGS. 3(a) to 3(c) (antecedent part) and FIG. 4 (consequent part) (a) and (b).

In this membership function, the fuzzy set degree (
Each label (fuzzy value) indicating the grade) is combined with the direction display group of (positive direction P/reference Z) and (large L/
The membership function that is set to display in combination with the degree display group of medium M and small S) and indicates the degree of banknote remaining amount Xl in Figure 3 (a) is as follows: 2: No amount remaining PS: Very little amount remaining PM: Remaining amount is slightly low PL: Remaining amount is sufficient.

The membership function showing the degree of use Xl for each day of the week in Figure 3 (b) is as follows: Z; day of the week with no use PS: day of the week with low use frequency PM: day of the week with normal use frequency PL: day of the week with high use frequency ing.

The membership function showing the degree of use X3 by time in Figure 3 (c) is as follows: 2: Time of no use PS: Time of low use PM: Time of normal use PL: Time of high use ing.

The membership function indicating the output degree of the maximum number of sheets to be fed out Yl in Figure 4 (a) is: Z: does not limit the maximum number of sheets to be fed PS: slightly limits the maximum number of sheets to be fed PM: PL limits the maximum number of sheets to be fed to some extent : Indicates that the maximum number of sheets that can be fed out is considerably limited.

The membership functions showing the degree of output of the replenishment notification value Y2 to the staff in FIG. : Indicates that a considerable number of replenishment sheets will be announced.

Furthermore, as an example of the setting of the fuzzy rule table 27 mentioned above, as shown in FIG.
(XI = PM), the day of the week where the usage level Xl by day of the week is very high (Xl = PL), and the usage level by time Xl is very high.
If 3 is used with the normal frequency of use (X3 = PM), transactions can be allowed to some extent until the automatic transaction machine 11 stops trading, and at that time, the FIE 25 will not restrict the withdrawal (Yl = Z) and will not limit the remaining amount. The output is set to replenish a small amount to the staff via the small quantity notification device 24 (Y2 = PS)
.

i f Xi = PM Xl = PLX3
=PM then YI=Z Y2=PS (Rule 2) If the amount of banknotes remaining in the automated teller machine, Xl, is a little low (XI = PM), the degree of usage by day of the week, Xl, is normal usage frequency (Xl = PM), usage level by time x
If 3 is a normal usage frequency (X3 = PM) and the amount of emissions is small, there is considerable trading capacity until the automatic transaction machine 11 stops trading, so at that time FIE25
sets the output to maintain the current status without limiting the feed or notifying the remaining amount (Y1=Z) (Y2=Z).

i f XI = PM Xl = PMX3
=PM then Yl =Z Y2 =
Z (Rule 3) If the amount of banknotes remaining in the automated teller machine is sufficient (X
i = PL), if the usage status by day of the week Xl is the normal usage frequency (Xl - PM), and the usage level by hour x3 is the normal usage frequency (X3 = PM), then
Since the automatic transaction machine 11 can accept transactions without requiring replenishment operations for a considerable period of time, at that time the FIE 25 does not restrict the payout or notify the balance, and sets the output to maintain the status quo (Y
l = Z) (Y2 = Z').

i f Xi = PL Xl = PMX3
=I'M then Yl =Z Y2 =
Z (Rule 4) If it is detected that the amount of banknotes remaining in the automated teller machine Xl is very low (XI = PS), on the day of the week where the usage level X2 by day of the week is extremely low (X2 = PS), Even if another usage degree X3 is a usage situation with a small amount of emissions, such as a normal usage frequency (X3 = PM), the automatic transaction machine 1
There is only a short time until 1 stops trading, so at that time FI
The E25 outputs an output to the dispensed number limiting device 23 to considerably limit the number of dispensed sheets (Yl = PL), and a device to notify the staff of the remaining amount! 24, the output is set to indicate immediate large-scale replenishment (Y2 = PL).

if XI =PS X2 =PSX3 =
PM then Yl=PL Y2=PL Thus,
(Rules 1 to 4) As shown in..., in response to the input of the antecedent part of if..., the consequent of then... Rules are set by corresponding departments.

The control operation of the banknote replenishment fuzzy control device of the automatic transaction machine 11 configured as described above will be explained with reference to the flowchart of FIG. 5.

In the transaction process of the automatic teller machine 11, the banknote remaining amount detection sensor S detects the degree of remaining banknotes, and from the detected remaining amount of banknotes, the FIE 25 infers the number of transactions until the transaction is stopped (first to second 2 steps 51-52).

As a result, if it is inferred that replenishment is necessary, the remaining quantity notification device 24
Please notify the staff that replenishment will be made immediately via the 3rd to
Fourth step 53-54), the FIE 25 also determines the allowable number of transactions that can be handled until the clerk replenishes the banknotes.
If it is inferred that the automatic teller machine 11 is down due to running out of banknotes before this replenishment operation is performed, the payout number limiting device 23 is set to limit the maximum payout limit number at the time of transaction.
(5th to 7th steps 55 to 57).

As mentioned above, when the automatic teller machine tends to be running low on banknotes, the staff is notified to replenish the banknotes, and the maximum number of bills that can be dispensed at one time is limited to the extent that the automatic teller machine does not go down. The automatic transaction machine can be used as an automatic transaction machine that has a high management ability to constantly maintain operation.

In the correspondence between this invention and the structure of the above-mentioned embodiment, the ejection amount limiting means of the present invention corresponds to the dispensed sheet number limiting device 123 of the embodiment, and similarly, the remaining quantity informing means corresponds to the remaining quantity informing device. 24, the detection means corresponds to the banknote remaining detection sensor S, and the fuzzy inference control means corresponds to the fuzzy inference engine (FIE) 25, but the present invention is limited only to the configuration of the above-described embodiment. It is not something that will be done.
