Fig. 4 is the diagram of circuit of the flow process of the parts that are used to the to illustrate elevator processing that improves planning system.
At first, if the maintenance personnel is via input part 18 designated analysis object parts (following is called " object parts "), then the parts information extraction portion 17A that improves plan auxiliary process portion 17 is by extracting the project data of object parts from Shipping Information data bank 11, the delivery information extraction 20a of object parts is stored in extracts result database 20 (step S1).
One example of the data structure that is stored in the delivery information extraction 20a that extracts result database 20 has been shown among Fig. 2.
In this delivery information extraction 20a, include the component identification information (component names), building name (customer identification information), project number, maintenance job number, number machine of order number (ccasual number), object parts, roughly specification, running beginning date etc.In addition, also can be that the project data that appends number of element types replaces component identification information, determines the object parts according to this number of element types.
In addition, information extraction portion 17A is according to the project data of mantenance data storehouse 12 extraction object parts, and the maintenance information extraction 20b with the object parts is stored in extraction result database 20 (step S2) thus.
Fig. 3 shows an example of the data structure that is stored in the maintenance information extraction 20b that extracts result database 20.
In this maintenance information extraction 20b, include building name (the building name N that official puts on record), order number (ccasual number), component identification information (component names), maintenance job number (number of setting), roughly specification, running beginning date, fault take place, are used a year number date, the moment, fault number take place fault, take on the CD of business quarters, fault is accepted the date etc.In addition, under the situation of the project of deleting component identification information, also can find component form, determine the object parts according to " order number ".
That is, in this maintenance information extraction 20b, include the fault generation information (for example more than any one in fault generation date, the fault generation moment, the fault number) that fault has taken place the indicated object parts.In addition, fault generation information is for example with representing fault year number by (fault take place date-running begins the date) * 24 times that calculate.
Female operational part 17B of group obtains shipping table number (female number) Ni to the object parts of same client's delivery based on the delivery information extraction 20a of the object parts of store management in extracting result database 20.And the female operational part 17B of group extracts female information 20c of group of shipping table number (female number) Ni that includes client's title, delivery opportunity, object parts, and is stored in and extracts result database 20 (step S3).
Then, the 17C of analyzing and processing portion extracts the shipping table that fault generation information that the maintenance information extraction 20b in the result database 20 contained and female information 20c of group contained and counts information based on being stored in, calculate that shipping table is counted in the middle of the shipping table number of the object parts shown in the information, the generation shown in the fault generation information platform number (CCS casual clearing station number) (step S4) of object parts of fault.
Thus, the 17C of analyzing and processing portion counts the CCS casual clearing station number of obtaining among Ni and the above-mentioned steps S4 according to the shipping table of obtaining among the above-mentioned steps S3, calculates the platform number of the object parts of regular event at the scene.That is to say, count Ni, can implement to accumulate hazard analysis, can correctly calculate fault rate according to the ratio that the CCS casual clearing station number is counted Ni with respect to shipping table by correctly grasping by delivery to the shipping table of on-the-spot object parts.
The 17C of analyzing and processing portion utilizes accumulation dangerous function H (t), reliability function R (t), unreliability function F (t) and fault probability of occurrence density function f (t) etc., carries out the generation of fail-safe analysis information and handles (step S5).
At this, the formula (1) below accumulation dangerous function H (t) utilizes is represented.
H (t)=∑ σ i/Ni ... formula (1)
In above-mentioned formula (1), Ni represents the shipping table number of the object parts that calculated by female operational part 17B of group, and σ i represents whether each object parts fault has taken place.For example, do not have at the object parts to be expressed as σ i=0 under the situation of et out of order, under the situation of the positive et out of order of object parts, be expressed as σ i=1.
Formula (2) below reliability function R (t) utilizes is represented.
R (t)=exp (H (t)) ... formula (2)
Formula (3) below unreliability function F (t) utilizes is represented.
F (t)=1-R (t) ... formula (3)
Therefore, the 17C of analyzing and processing portion carries out the Weibull analyzing and processing.That is, the 17C of analyzing and processing portion derives following formula (4) according to above-mentioned formula (2), formula (3).
LnH (t)=-ln (ln (1-F (t)) ... formula (4)
And, be applicable to have transverse axis X, on the dangerous paper of the Weibull of the system of axes of longitudinal axis Y, generate following approximant (5) and (6) by linear approximation, determine η, m.η is the parameter of decision yardstick, and m is as the form parameter of the slope of straight line (Weibull modulus).
H (t)=(t/ η) m ... formula (5)
Ln H (t)=m lnt-m ln η ... formula (6)
The 17C of analyzing and processing portion generates fail-safe analysis information (step S51) shown in Figure 5 by implementing above-mentioned analyzing and processing.
In addition, the 17C of analyzing and processing portion obtains the necessary Functional Analysis result (step S52) of the analysis result (with reference to Fig. 6) of unreliability function F (t) and the analysis result (with reference to Fig. 7) of fault probability of occurrence density function f (t) etc., and, importing by the Weibull analysis obtains Weibull analysis result (with reference to Fig. 8) (step S53), and then calculate replacing opportunity (with reference to Fig. 9) (step S54) of the object parts of having considered risk, and these results are stored in the fail-safe analysis data bank 21 manage.
Particularly Fig. 5 to Fig. 9 is described.
Fig. 5 is the data structure example that is stored in the fail-safe analysis information in the fail-safe analysis data bank 21.
In fail-safe analysis information, each object parts includes time, Ln (t) (the transverse axis value of the Weibull analysis chart of Fig. 8), σ i, dangerous values h (t), H (t), F (t) and LnH (t) etc.In addition, though illustrate, but in fail-safe analysis information, also include client's title (customer identification information), the component identification information that is used for the identifying object parts and the fault probability of occurrence density function f (t) etc. that are used for the client that the identifying object parts are sent to.
In addition.With the situation of corresponding σ i=0 of time under the object parts do not have fault, so normal operating time of indicated object parts.Fault has taken place in the object parts under the situation of σ i=1, so the fault of indicated object parts (time of origin).
Ln (t) is and this Ln Napier's logarithm of (t) corresponding time, corresponding to the transverse axis of the Weibull analysis chart of Fig. 8.LnH (t) is the Napier's logarithm of H (t), corresponding to the longitudinal axis of the Weibull analysis chart of Fig. 8.
Fig. 6 is the coordinate diagram of analysis result that is illustrated in the unreliability function F (t) of the object parts that comprise in the fail-safe analysis information.In this coordinate diagram, show and the cooresponding unreliability F of the time of run of object parts (t) according to each product (type of elevator).
According to this coordinate diagram, confirm passing according to the CCS casual clearing station number of the object parts of each time of run, thereby can calculate as the time of run (replacing opportunity) in life-span of the object parts that constitute first and second elevator etc. with adding up.
Fig. 7 is the coordinate diagram of analysis result that is illustrated in the fault probability of occurrence density function f (t) of the object parts that contain in the fail-safe analysis information.In this coordinate diagram, the same with the coordinate diagram of Fig. 6, show value with the cooresponding fault probability of occurrence of the time of run of object parts density function f (t) according to each product (type of elevator).
The value of the fault probability of occurrence density function f (t) of the object parts of broken line 41 expression formations first elevator.The value of the fault probability of occurrence density function f (t) of the object parts of second elevator that broken line 42 expression formations are other.
The calculating of this fault probability of occurrence density function f (t) utilizes downtime and unreliability function F (t) to carry out.For example, obtain maxim F (nT) Max (n is a positive integer) of F (t) according to each time of failure interval T, the value that fault probability of occurrence density function f (t) obtains for the maxim in the interval of the maxim from current interval before deducting, i.e. f (t)=F (nT)-F ((n-1) T).Wherein, set F (0)=0.
In addition, in the example shown in the coordinate diagram of Fig. 7, the mean down time MTBF till the object parts et out of order (Mean Time Between Failure) as aviation value be 140400 (hour).
Therefore,, confirm to constitute mean down time etc. of the object parts of first, second elevator, can calculate replacing opportunity of these object parts etc. thus according to this coordinate diagram.
Fig. 8 is illustrated in that the accumulation dangerous function H (t) to the object parts that contains in the fail-safe analysis information carries out the Weibull analysis and the figure of the analysis result that obtains.In the figure, show drawing (plot) value with the cooresponding LnH of Napier's logarithm Ln (t) (t) of the time of run of object parts.
The drawing value becomes linear approximation as above-mentioned formula (4)～formula (6) is illustrated, draw according to its slope, and the value of m is 1.6327.
Analyze by this Weibull, the lifetime data that can access with wider range is the result of object.In addition, according to the value of m, the failure mode of incipient failure type (m＜1) that can the object-aware parts, chance failure type (m=1), wear out failure type (m＞1).
For example, therefore the form parameter m=1.6327 of object parts shown in Figure 8, is the failure mode of wear out failure type as can be known.The form parameter m of object parts also can be stored in fail-safe analysis data bank 21.
In addition, can expect, according to the environment for use of parts promptly for example the installation site of parts, the time of starting with, change the difference of production time etc., can have influence on time of failure.Therefore, the 17C of analyzing and processing portion obtains environment for use information that is stored in environment for use information database 13 or the crisis management information that is stored in risk management data bank 14, and the value that the unreliability function F (t) that utilizes the object parts or accumulation dangerous function H (t) are calculated is weighted.
Fig. 9 implements risk management and determines the replacing figure on opportunity the value of the unreliability function F (t) of the object parts that comprise in fail-safe analysis information.
This figure is the figure that has appended risk curve 51 in the coordinate diagram of Fig. 6.Risk curve 51 expression is multiplied by the cost of the related substrate of object parts or maintenance personnel's unit price etc., the cost that replacing spent of expression and the cooresponding object parts of each time of run.
By appending such risk curve 51, compare with the coordinate diagram of Fig. 6, can remove and calculate the more suitably replacing opportunity (step S54) of object parts, can realize the optimization on the opportunity of changing.
On the replacing opportunity that the 17C of analyzing and processing portion goes out temperature, humidity, number of starts or the aforementioned calculation that contains in the specification environmental information (replacing Best Times) etc., in fail-safe analysis data bank 21, apply flexibly the seat limit data as the fail-safe analysis information storage.Judge the replacing opportunity of object parts etc. based on this limit data (fail-safe analysis information).
That is, by a series of processing of above-mentioned steps S5, can determine the object parts that constitute elevator with the year number et out of order of what degree, be fault year number.
But, even calculate year number that is out of order, this in fault year number be the data after the fault.Therefore, the analytic target parts are why to plant reason fault has taken place, if change these object parts before fault, just can elevator device not brought influence and it is turned round safely.
Therefore, the 17C of analyzing and processing portion is extracted in problematic part in environment for use or the using method according to repair message and environment for use analyzing failure cause (1).And the 17C of analyzing and processing portion is that the basis is shown in display part 19 with the improvement method with this extraction result, and feeds back to elevator setting scene (step S6).
Promptly, the 17C of analyzing and processing portion obtains maintenance information extraction 20b that is stored in the object parts that extract result database 20 and the environment for use information that is stored in the object parts of environment for use information database 13, utilize MT (Mahalanobis-Taguchi) method or analysis software etc., analyze the fault cause that brings influence to the fault of object parts.Thus, extract the fault cause of the stronger reason of degree of influence, find out the long-term improvement method that is used to realize the object parts, and should the improvement method feed back to maker as the object parts.
In addition, in the analysis of fault cause, also can use certain in MT method or the analysis software.
And then the 17C of analyzing and processing portion comes analyzing failure cause (2) (step S7) according to delivery test figures and manufacturing record information.
Promptly, the 17C of analyzing and processing portion obtains the delivery test figures (inputoutput data of circuit, the characteristic data of parts etc.) of the object parts that are stored in delivery experimental data base 15 and is stored in the manufacturing record information (device information, manufacturing environment, Fabrication procedure etc.) of the object parts of making record information data bank 16, by utilizing MT method or analysis software etc., analyze the causal relationship between delivery test figures and the manufacturing record information, and with its analysis result as the fail-safe analysis information storage in fail-safe analysis data bank 21.
At this moment, the 17C of analyzing and processing portion is if extract abnormal data when fabrication phase and delivery, then unusual object parts have taken place refusal, and, extract the causal relationship between delivery test figures and the manufacturing record information, analyze unusual reason (fault cause) takes place.For example, at fault cause is to have occurred under the situation of problem in the batch of object parts or manufacturing environment, using method, the manufacturing record information of fault cause that will become these object parts as the fail-safe analysis information storage in fail-safe analysis data bank 21, and, above-mentioned manufacturing record information is fed back to the maker of object parts, impel maker that the undesirable condition that takes place when the object parts are delivered is implemented to improve.
In addition, even be not the stage of delivery test but in the object parts, found equally in object parts delivery back under the unusual situation also be, the 17C of analyzing and processing portion extracts the causal relationship between delivery test figures and the manufacturing record information, implement to take place the analysis of unusual reason (fault cause), with its analysis result as the fail-safe analysis information storage in fail-safe analysis data bank 21, and, above-mentioned manufacturing record information is fed back to the maker of object parts, impel maker that the undesirable condition that takes place when the object parts are delivered is implemented to improve.
Like this, by analyzing failure cause, as shown in Figure 12, the 17C of analyzing and processing portion can calculate before fault and change prediction opportunity (step S8).
Figure 10 to Figure 12 is the figure that is used to illustrate the result who utilizes MT method or analysis software.
Figure 10 is the figure that expression utilizes the result's that the MT method analyzes a example.In the example of Figure 10, illustrated by the Reference data of the 17C of analyzing and processing portion making and the relation between object components A～D.These objects components A～D is the same parts that constitute different respectively elevators, is the current parts that turning round.
What on the other hand, the middle section of Figure 10 was represented is the Reference data (reference space) of being made by the 17C of analyzing and processing portion.That is to say that the MT method is according to the position of object components A～D and judges the method for each object components A～D undesirable condition separately as the distance relation between the Reference data at center.
Particularly, for example the position of object components A is in position away from Reference data.This expression with the benchmark that does not have et out of order away from, can be judged to be the generation undesirable condition the possibility height.On the other hand, the position of object parts C is in the position near Reference data.Therefore, can be judged to be among the object parts C undesirable condition does not take place, and in running normally.
Thus, the environment (environment for use) that the object parts of undesirable condition are used understand to take place or make record information etc., can analyzing failure cause (1), (2).
Figure 11 is the figure of visual example that expression utilizes the result of analysis software.2 coordinate Figure 61,62 have been shown in this Figure 11.
The distribution of time of run according to each type of the elevator that coordinate Figure 61 indicated object parts are constituted (year number) and number of starts.The distribution according to the time of run of delivery year number of coordinate Figure 62 indicated object parts.Thus, the environment that the object parts of lacking by understanding running year number are used etc. can analyzing failure cause.
Figure 12 is the analysis result based on above-mentioned Figure 11, the figure of the influence that brings according to the time of run of reason indicated object parts (year number), to satisfaction.The content of this Figure 12 is shown in display part 19, is prompted to the maintenance personnel.
Illustrated under X=2000 hour the situation of time of run according to each product (fault is changed opportunity) among Figure 12, given value that the time of run of object parts brings each reason of influence, be worth cooresponding time of run and satisfaction with this at the object parts.At this, bring the reason of influence as the time of run of giving the object parts, include till check day during, average number of starts (moon), accumulate number of starts, travel distance (monthly average), stop floor etc.

In addition, the time of run of these object parts can change, and for example under the time of run of these object parts is set to 3000 hours situation, the value with cooresponding each reason of this time of run will be shown.
According to the example of this Figure 12 as can be known, the few degree of satisfaction De Minus be sharply to reduce under the situation that the accumulation cranking time reduces, and, the slope between greatly time the in the running, compare the influence that the time of run to the object parts brings with travel distance bigger.That is, we can say under the situation that the value that makes each reason changes that when the variation of satisfaction or time of run was fierce, the influence that its reason brings for the time of run of object parts was big.On the contrary, we can say under the situation that the value that makes reason changes that if the variation of this satisfaction or time of run is more slow, then the influence of bringing for the time of run of object parts of this reason is little.
In addition, investigate the influence that the time of run to the object parts brings, then can find out several reasons with considerable influence if for example increase the reason project of specification, temperature, humidity, manufacturing resume etc. roughly.
