The recommended usage time of the module to be replaced is used as a standard replacement time, and can be calculated as a comparison replacement time with a target replacement time of the module to be replaced.
106, calculating target replacement time according to the equipment parameters and the module parameters;
the target replacement time refers to the replacement time of a module which is predicted to possibly need to be replaced in the self-service equipment, namely the replacement time of the module to be replaced. The target replacement time can be calculated according to the equipment parameters of the self-service equipment and the module parameters of the self-service equipment module. Since the target replacement time is related to the device parameter and the module parameter, the target replacement time can be calculated from the device parameter and the module parameter.

The target replacement time can be calculated according to the equipment parameters of the self-service equipment and the module parameters of the self-service equipment module. And replacing the module to be replaced at regular time according to the calculated target replacement time. For example, assuming that the calculated target replacement time of each module is 44 days and 40 days, the module to be replaced should be replaced at 44 days and 40 days. The target replacement time obtained through calculation is the optimal replacement time of the module to be replaced, the module to be replaced is replaced according to the target replacement time, the replacement cost of the self-service equipment module is the lowest, meanwhile, the module to be replaced is replaced in time in the optimal replacement time, sustainable normal work of the self-service equipment can be guaranteed, the module is replaced before the self-service equipment module breaks down, and the experience feeling of a user is improved.

for example, the shutdown time T of a certain self-service device is set to be 1 day, the total operation time W is set to be 200 days, the failure times of each module are respectively 1 time and 3 times, and the recommended service life of the corresponding module is set to be 40 days and 40 days. Thus, the standard replacement time of each module to be replaced is 40 days and 40 days respectively; then, the failure rate is calculated, and the failure rate of each module to be replaced is a1：1×1/200＝0.5％、a21.5% for 1 × 3/200. The failure rate of each module to be replaced is a1＝0.5％、a21.5%. Calculating the failure rate a of each module according to the formulaiThe fault degree of each module of the self-service equipment can be reflected, and meanwhile, the target replacement time of the module to be replaced can be calculated, and the target replacement time is the optimal replacement time of the module to be replaced.
And 204, calculating the target replacement time of each module to be replaced according to the fault rate of each module to be replaced and the standard replacement time of each module to be replaced.
The failure rate of each module to be replaced refers to the probability of failure corresponding to each module which is predicted to possibly need to be replaced in the self-service equipment, and the standard replacement time of each module to be replaced refers to the recommended service time of the module corresponding to each module which is predicted to possibly need to be replaced. In one embodiment, the target replacement time may be calculated according to the failure rate and the standard replacement time, for example: calculating to obtain the failure rate a of each moduleiThen, the failure rate a of each module can be determinediAnd calculating the module parameters of the self-service equipment module to obtain target replacement time, for example, setting N as the standard replacement time (unit: day) of the module, and setting M as the template replacement time (unit: day) of the module, and calculating according to the following formula:
(1-ai)N＝P
if the obtained number P is not more than 80%, the target replacement time of the module is M-N days, namely the target replacement time is equal to the standard replacement time; if P is more than 80%, the next calculation is carried out:
(1-ai)M＝80％
solving the equation, rounding down M obtained by calculation, and obtaining the target replacement time of the module by the obtained integer. According to the equipment parameters and the module parameters of the self-service equipment and in combination with standard replacement time calculation, the target replacement time of the module to be replaced, namely the optimal replacement time of the module to be replaced can be obtained. According to the target replacement time which is obtained by the calculation method and corresponds to the modules to be replaced one by one, the replacement cost of the modules to be replaced can be reduced in a targeted manner.
As shown in fig. 3, in an embodiment, calculating a target replacement time of each module to be replaced according to the failure rate of each module to be replaced and the standard replacement time of each module to be replaced includes:
and 302, calculating a target replacement rate corresponding to each module to be replaced according to the failure rate of each module to be replaced and the standard replacement time of each module to be replaced.
The failure rate of each module to be replaced refers to the probability of failure corresponding to each module which is predicted to be replaced possibly in the self-service equipment; the standard replacement time of each module to be replaced refers to the recommended service time of the module corresponding to each module which is predicted to possibly need to be replaced; the target replacement rate corresponding to each module to be replaced refers to the probability that each module which is predicted to possibly need to be replaced needs to be replaced, based on the failure rate, and the target replacement rate can be obtained by calculation according to the failure rate and the standard replacement time, for example: setting the target replacement rate as P and the failure rate of each module to be replaced as aiAnd setting N as the standard replacement time (unit: day) of the module, and calculating according to the following formula to obtain a target replacement rate P:
P＝(1-ai)N
according to the fault rate of each module to be replaced and the standard replacement time of each module to be replaced, the probability of the module to be replaced corresponding to the module to be replaced needing to be replaced can be calculated, and the value P calculated by the formula serves as the target replacement rate.
And step 304, acquiring a preset replacement rate.
The preset replacement rate refers to a preset probability that each module which is predicted to possibly need to be replaced needs to be replaced and corresponds to the module which needs to be replaced. The preset replacement rate can be used as a theoretical replacement rate and compared with the target replacement rate, so that whether the target replacement rate meets the requirement or not is judged. That is, the magnitude of the preset replacement rate and the target replacement rate is compared: when the target replacement rate is not greater than the preset replacement rate, judging that the target replacement rate meets the requirement, and thus obtaining that the target replacement time is equal to the standard replacement time; and when the target replacement rate is greater than the preset replacement rate, judging that the target replacement rate does not meet the requirement, and further calculating to obtain the target replacement time. In one embodiment, assume that the obtained preset replacement rate is 80%, and the target replacement rate is P. When P is less than or equal to 80%, judging that the target replacement time is equal to the standard replacement time; when P is greater than 80, the next calculation of the target replacement time is performed. The preset replacement rate is obtained and can be used as a comparison value of the target replacement rate, so that the target replacement time can be more accurately judged and calculated.
And step 306, calculating the target replacement time of each module to be replaced according to the preset replacement rate and the target replacement rate.
The preset replacement rate refers to a preset probability that each module which is predicted to possibly need to be replaced corresponds to and needs to be replaced, and the target replacement rate refers to a probability that each module which is predicted to possibly need to be replaced corresponds to and needs to be replaced. In one embodiment, the target replacement time may be calculated by comparing the preset replacement rate and the target replacement rate, for example: if the failure rate of the module to be replaced is 1.5 percent, the preset replacement rate is 80 percent, and the standard replacement time of the module to be replaced is 40 days, the corresponding target replacement rate is calculated to be P (1-1.5 percent)40≈0.5463<80%, if the target replacement rate is smaller than the preset replacement rate, the target replacement time of the module to be replaced is equal to the standard replacement time, that is, M is equal to N is equal to 40 days; when the failure rate of the module to be replaced is 0.5%, the preset replacement rate is 80%, and the standard replacement time of the module to be replaced is N40 days, calculating to obtain the failure rate of the module to be replaced which is 0.5%, and the standard replacement time of the module to be replaced which is N40 daysUntil the corresponding target substitution rate is P ═ 0.5%)40≈0.8183>80%, if the target replacement rate is greater than the preset replacement rate, performing the next calculation, which may be according to a formula:
(1-ai)M＝80％
solving the above equation, rounding down the calculated M, and obtaining the target replacement time of the module as the integer, such as: (1-0.5%)M80%, M ≈ 44 days are calculated, and the target replacement time is 44 days. And predictably processing the target replacement time of each module to be replaced according to the target replacement rate and the preset replacement rate, and accurately obtaining the target replacement time of each module to be replaced according to the actual condition of each module to be replaced.
In one embodiment, as shown in fig. 4, the module parameters further include: the replacement cost of each module to be replaced; the replacing the module to be replaced according to the target replacing time comprises the following steps:
the replacement cost of each module to be replaced refers to the sum of various expenses required to be spent when the self-service equipment module is replaced, such as: the replacement cost is traffic expense, staff wages and other expenses; the failure rate of each module to be replaced refers to the probability of failure corresponding to each module predicted to be possibly replaced; the failure probability accumulated sum corresponding to each interval refers to the sum obtained by accumulating the failure rates of all the modules to be replaced in a single interval. According to the replacement cost and the failure rate, the module to be replaced is divided into intervals, so that the failure probability corresponding to each interval is accumulated and equal, and the method can be as follows: and sequencing the replacement cost of each module to be replaced from small to large, and dividing intervals according to the sequencing of the replacement cost, so that the accumulated sum of the fault rates of a plurality of groups of modules to be replaced in each interval and sequenced according to the replacement cost is equal. By dividing the interval to carry out interval planning, the efficiency of the module to be replaced can be optimized.
The spare part module is a spare module for replacing the module to be replaced, the regional spare part library is a warehouse for storing the spare part module, and the normal service life of the spare part module is the maximum normal working time of the spare part module. The normal service life of each spare part module is obtained, and the spare part modules can be in one-to-one correspondence with the to-be-replaced modules in each interval, so that the spare part modules corresponding to the spare part modules can be selected to replace the to-be-replaced modules.
And 406, determining an interval corresponding to each spare part module according to the normal service life of the spare part module.
The normal service life duration of the spare part module refers to the maximum normal working time of the spare part module, the interval corresponding to each spare part module refers to the interval of the to-be-replaced module corresponding to each spare part module, and the number of the intervals of the to-be-replaced modules is equal to the number of the spare part modules. In one embodiment, the normal life durations of the spare part modules may be sorted in the order from small to large, and the intervals of the modules to be replaced, which are divided according to the replacement cost of the modules to be replaced and the failure rate of the modules to be replaced, correspond one to one, so that the interval corresponding to each spare part module may be determined. According to the normal service life duration of the spare part module, the interval corresponding to the spare part module is determined, and the replacement requirement of the module to be replaced can be met.
And 408, obtaining a target spare part module corresponding to each module to be replaced according to the matching of the interval corresponding to the module to be replaced and the interval corresponding to the spare part module.
The target spare part module is a spare module corresponding to the module to be replaced and used for replacing the module to be replaced, the section corresponding to the module to be replaced is a section of the module to be replaced which is divided according to the replacement cost of the module to be replaced and the fault rate of the module to be replaced, the section corresponding to the spare part module is a section of the module to be replaced which corresponds to each spare part module, and the number of the sections of the module to be replaced is equal to the number of the spare part modules. Because the number of the intervals of the modules to be replaced is equal to the number of the spare part modules, the intervals corresponding to the spare part modules can be matched with the intervals corresponding to the modules to be replaced one by one, and the target spare part modules corresponding to each module to be replaced can be obtained according to the matched interval relation. By obtaining the target spare part module corresponding to each module to be replaced, the most appropriate spare part module of each module to be replaced can be obtained.
And step 410, replacing the module to be replaced with the target spare part module according to the target replacement time.
The target replacement time refers to the replacement time of a module which is predicted to be replaced possibly in the self-service equipment, namely the replacement time of the module to be replaced; the module to be replaced refers to a module which is predicted to be possibly replaced; the target spare part module is a spare module corresponding to the module to be replaced and used for replacing the module to be replaced. Because of the one-to-one correspondence between each module to be replaced and the target spare part module, the module to be replaced can be replaced with the target spare part module at the time point of the target replacement time according to the one-to-one correspondence. And replacing the module to be replaced with the target spare part module according to the target replacement time, so that the module to be replaced can be replaced with the most appropriate spare part module at the optimal replacement time, and the replacement method of the self-service equipment module is optimized.
As shown in fig. 5, in an embodiment, dividing the modules to be replaced into sections according to the replacement cost of each module to be replaced and the failure rate of each module to be replaced, so that the sum of the failure probabilities corresponding to each section is equal, includes:
The preset interval number refers to the number of preset intervals of the modules to be replaced, which are divided according to the replacement cost of the modules to be replaced and the fault rate of the modules to be replaced. Because the sum of the payment probabilities corresponding to each interval needs to be equal, the number of the divided intervals needs to be obtained, and the average replacement probability of each preset interval can be obtained through calculation.
The failure rate of each module to be replaced refers to the probability that each self-service equipment module which is predicted to be possibly replaced possibly fails; the preset number of intervals refers to the number of preset intervals of the modules to be replaced, which are divided according to the replacement cost of the modules to be replaced and the fault rate of the modules to be replaced; the replacement cost of each module to be replaced is the sum of various expenses required to be spent in replacing the self-service equipment module; the average replacement probability refers to the probability that the module to be replaced in each section is likely to be replaced. The average replacement probability corresponding to each interval can be calculated according to the failure rate of each module to be replaced, the number of preset intervals and the replacement cost of each module to be replaced. For example: sequencing the replacement cost of each module to be replaced from small to large, so as to obtain the sequencing of the modules to be replaced according to the sequencing of the replacement cost; accumulating the fault rate of each module to be replaced according to the sequence of the modules to be replaced, and obtaining the total fault rate of all the modules to be replaced; and calculating a quotient of the total failure rate and the number of the preset intervals, wherein the obtained quotient is the average replacement probability corresponding to each interval.
The average replacement probability refers to the probability that the module to be replaced in each section is likely to be replaced, and the replacement cost of each module to be replaced refers to the sum of various expenses required to be spent in replacing the self-service equipment module. In one embodiment, each module to be replaced is sequenced according to the sequence of the replacement cost from small to large, and all the modules to be replaced are divided into intervals, so that the cumulative sum of the failure rates of the modules to be replaced in each interval is equal to the average replacement probability, and the obtained interval is the interval corresponding to the module to be replaced. The module to be replaced is subjected to interval division, and then area overall configuration is carried out according to the divided intervals, so that the interval operation cost is the lowest, and the requirement of benefit maximization is met.
As shown in fig. 6, in an embodiment, the step of determining the interval corresponding to each module to be replaced by dividing the module to be replaced according to the average replacement probability and the replacement cost of each module to be replaced includes:
and step 602, sorting according to the replacement cost of each module to be replaced from small to large.
The replacement cost of each module to be replaced refers to the sum of various expenses required to be spent in replacing the self-service equipment module. And sequencing each module to be replaced according to the sequence of the replacement cost from small to large, so that the sequencing of the modules to be replaced can be obtained, the replacement of the self-service equipment modules can be arranged comprehensively, and the expected value of the replacement cost of the modules is minimum.
And step 604, sequentially accumulating the fault rates of the modules to be replaced according to the sequence to obtain a probability accumulated sum, and dividing the modules to be replaced which participate in accumulation into the same interval when the probability accumulated sum is equal to the average replacement probability.
The sequence is obtained by sequencing the modules to be replaced according to the replacement cost of each module to be replaced from small to large, the average replacement probability is the probability that the modules to be replaced in each interval are likely to be replaced, and the failure rate of each module to be replaced is the probability that each self-service equipment module which is predicted to be likely to need to be replaced is likely to fail. Since the probability that the modules to be replaced in each section are likely to be replaced is the same, the sum of the failure rates of the modules to be replaced in each section is equal to the average replacement probability. Namely, sequencing is performed according to the replacement cost of each module to be replaced from small to large, the failure rates of the modules to be replaced are accumulated in sequence until the sum of the failure rates is equal to the average replacement probability, the obtained probability that the modules to be replaced in each interval are possibly replaced is the same, and the modules to be replaced participating in accumulation are divided into the same interval. The interval of the module to be replaced is limited and divided through the sequencing of the average replacement probability and the replacement cost, and the requirement of the module to be replaced with the lowest replacement cost can be met.
And 606, accumulating the fault rates of the modules to be replaced which do not participate in accumulation again according to the sequence, dividing the modules to be replaced which participate in accumulation into the same interval when the sum of the probability is equal to the average replacement probability, and determining the interval corresponding to each module to be replaced by analogy.
The sequence is obtained by sequencing the modules to be replaced according to the replacement cost of each module to be replaced from small to large, the average replacement probability is the probability that the modules to be replaced in each interval are likely to be replaced, and the failure rate of each module to be replaced is the probability that each self-service equipment module which is predicted to be likely to need to be replaced is likely to fail. Since the probability that the modules to be replaced in each section are likely to be replaced is the same, the sum of the failure rates of the modules to be replaced in each section is equal to the average replacement probability.
