Description
Technical field
The present invention relates to a kind of operation analysis apparatus, related charge book data gather, analyze in the production of the product that it is made the flow chart implementing simultaneously to be shared, demonstration or export its analysis result to the outside.
Background technology
For example, making in the factory, generally dividing and make flow chart, sharing by a plurality of operators and respectively make flow chart, operation sewing machine and implement to make operation for the parts of each quilt.
Make that operation is divided into a plurality of flow charts and under the situation about sharing that product is related, preferred All Jobs operation is carried out simultaneously, produce delay etc. with the flow chart that a part of operator is shared, in order to make the operation high efficiency, must reduce the fluctuation of each operator's operation required time.
Therefore, existing operation analysis apparatus, for example such as in the patent documentation 1 record, according to the operator's customizing messages that is used for determining the operating personnel, the operation customizing messages that is used for definite flow chart and the operation required time of each flow chart, certain flow chart that each operating personnel is carried out and needed time of each flow chart is record one by one, collects this data, passes through operation analysis apparatus, they are gathered, analyze, the display analysis result.
As shown in figure 16, in the manufacturing of sofa, show, separately the flow chart of the parts shared is made the example of operation by five operators.
In Figure 17, the combined data that shows following data with form, promptly, the actual job time that the operation ID of the operation that each operator distributed (operation customizing messages), each operation are once made the needed productive temp time of operation (operation required time) and at each operator productive temp time of each operation added up to, data D1 represents to carry out process distribution and adjusts preceding state, and data D2 represents the adjusted state of process distribution.
In addition, Figure 18 represents operator and the relation of actual job between the time, and broken line L1 is based on that data D1 makes, and broken line L2 is based on that data D2 makes.
Here, so-called " actual job time ", be meant and sharing by a plurality of operators under the situation of the flow chart that belongs to a certain product, the value that productive temp time of each operation is added up to.Promptly, the actual job time, being expression, needed to make operation all for product, the value of each operator's working time, by so that the mode that is evenly distributed of practical operation time is distributed each operation to each operator, thereby eliminate the delay that the delay owing to a part of operation causes product to be finished, can realize obtaining the high efficiency common operation of line balancing.
By broken line L1 as can be known, in all operations person, the operator's of operator ID1113 the actual job time is longer, and the operator's of operator ID1106 the actual job time is shorter, and line balancing is relatively poor.In this case, will distribute to operator (1106) and adjust a part of flow chart, for example operation 71 that operator (1113) distributes.Thus, shown in broken line L2, each operator's actual job lead time descends significantly, and it is good that line balancing becomes.
Existing operation analysis apparatus, in order successfully to carry out above-mentioned analysis and adjustment, it has following function, promptly, the charge book data of collecting from each sewing machine are gathered, carry out generation and the demonstration of above-mentioned data D1, the editing operating of the line data of going forward side by side.In addition, in the handled combined data of operation analysis apparatus, productive temp time of each operation, be with carried out many working times of making operation divided by number of packages calculating mean value, carry out the generation of data D1, and on average calculate the average productive temp time of this moment by addition.
But, at the scene of making operation, produce under the situation about postponing in a part of operation that certain operator distributed, there is not the operator of work temporarily to help at hand to a part of making predetermined number of packages that postpones in the operation.In this case, the operator who helps imports by the operation ID of help operation, and the part that will help counts in the charge book data.
With form the example of operation analysis apparatus to the combined data D3 of this charge book data sink General Logistics Department is shown among Figure 19.As the operation benchmark, that is, the content of the charge book data after gathering gathers at each operation this combined data D3 with above-mentioned data D1.
The regional A1 of this combined data D3, the example that operation is carried out to operation (45) in expression operator (1106), (1067), (1105).In addition, in combined data D3, " average productive temp time (1) " is the average productive temp time (the average productive temp time that also can be called operator's benchmark) of each operator each operation of carrying out, " average productive temp time (2) " is the average productive temp time (the average productive temp time that also can be called the operation benchmark) of each operation, two average productive temp times (1) and (2), is identical value in each operation under by the situation of single operation person operation, but shown in operation (45), being divided the work situation that operation carries out by a plurality of operators under, an operation is different values.
And in existing operation analysis apparatus, a plurality of operators divide the work the calculating of average productive temp time (2) of the operation benchmark under the situation of operation to an operation, calculate by the addition average treatment.Specifically, shown in the regional A1 of combined data D3, the average productive temp time (1) three operators is respectively 85[s], 103[s], 69[s] situation under, average productive temp time (2)=(the 85+103+69)/3=86[s of operation benchmark], by will take on divide the work operation the operator separately " average productive temp time (1) phase adduction calculates divided by number.
In addition, existing operation analysis apparatus, as shown in figure 20, also carrying out with operator is the calculating of the combined data D4 of benchmark.This combined data D4 is at each operator, the data that average productive temp time (2) of the production quantity of the operation ID of operation distribution, each operation, each operation, each operator's the actual job time is gathered.
The regional A2 of this combined data D4, expression is divided the work average productive temp time (2) of operation (45) of operation by operator (1106), (1067), (1105) three people, here also is to adopt three operators' average productive temp time (1) addition is average and average productive temp time (2) of obtaining (=86[s]).
And, shown in combined data D4, in existing operation analysis apparatus, calculating actual job during the time at each operator, for operation (45), also be with and average productive temp time (2)=86[s that obtain average by above-mentioned addition by operation that a plurality of operator divides the work] as take on divide the work operation each operator the shared average productive temp time and use.
Patent documentation 1: the spy of Japan opens flat 04-13546 communique
Summary of the invention
But, as mentioned above, whenever for dividing the work the operation of operation by a plurality of people, during the average productive temp time (2) of calculation process benchmark, only be that to carry out everyone addition of productive temp time average, can't obtain correct mean value.That is, described here correct mean value is meant to have a plurality of operators' the operator of average ability of operation is divided the work in same operation operation, finish this operation required in case of necessity between.
The productive temp time with described operator (1106), (1067), (1105) is that example describes.If the unit of the average productive temp time (1) shown in the combined data D3 is second ([s]), then the processing speed [part/s] of each individual operation (45) is respectively (1/85) [part/s], (1/103) [part/s], (1/69) [part/s], if so carry out operation (45) jointly, then this required time is ((1/85)+(1/103)+(1/69))
-1=27.8[s].Thus,, then need 3 times time if carry out operation (45) by people of the operator with average ability, thus the correct average productive temp time (2) should for
But above-mentioned addition mean value is 86[s], with correct required time 83[s] inconsistent.
Thus, there is following problem, promptly, an operation is being divided the work under the situation of operation, can't correctly calculate the actual job time that is used to estimate line balancing,, also can not enhance productivity actual job time even adjust operator's process distribution based on this.
And, in the computing method of existing actual job time, an operation is being divided the work under the situation of operation, do not consider each operator's operation ratio.If dividing the work the situation of operation with described operator (1106), (1067), (1105) is that example describes, then for example shown in the combined data D4, operator (1105) has carried out 30 making for operation (41), (42), (44), but has only made 5 for operation (45).That is, although carried out other operation sixth make quantity, when the calculating of actual job time conduct and other operation equal number make thing, obtain the average productive temp time (2) by additive operation.
Also, can't correctly calculate the actual job time, thereby can't realize enhancing productivity by the process distribution of adjusting the operator owing to this reason.
The objective of the invention is, correctly adjust operator's process distribution, realize the raising of production efficiency.
The invention of technical scheme 1 record, be that the charge book data relevant with the production of following product are gathered, analyze on this basis, and its analysis result is shown or export to the outside, described product is produced by the operation that a plurality of operators carry out the flow chart of sharing separately simultaneously, it is characterized in that, have: data capture unit, it obtains the charge book data, and these charge book data comprise operator's customizing messages, the flow chart customizing messages of bearing described each flow chart, the operation required time customizing messages that reaches each flow chart; Operation required time computing unit, it for each flow chart, obtains each operator's operation required time in all or a part of scope of described each charge book data; And actual job time calculating unit, it is for each described operator, the operation required time of the flow chart that this operator is carried out adds up to, calculate the actual job time, described actual job time calculating unit, when in described each charge book data, existing a flow chart to divide the work operation required time customizing messages under the situation of operation by a plurality of operators, utilize harmonic average to make it equalization by operation required time with these operators' described flow chart, based on the operation required time of obtaining by this equalization, calculate each described operator's the actual job time.
The invention of technical scheme 2 records, it is characterized in that, has the identical formation of invention with technical scheme 1 record, simultaneously, in described each charge book data, comprise the production quantity information of each operator in each flow chart, described actual job time calculating unit, when in described each charge book data, existing a flow chart to divide the work operation required time customizing messages under the situation of operation by a plurality of operators, on the operation required time that calculates utilizing described averaging of harmonic average, multiply by each operator's the production quantity production quantity shared ratio all with respect to the flow chart of described division of labor operation, on this basis, add up to the operation required time of other flow chart, thus the actual job time of calculating described each operator.
In addition, " operation required time customizing messages " and " the production quantity information " of " charge book data ", its content is not limited to directly show required time or production quantity, also can be by carrying out computing, as a result of obtaining the indirect consequence of required time and production quantity.For example be the expression sewing machine make beginning or the information of the finish time etc. at every turn, obtain required time according to these differences constantly, perhaps also can for once make must the record some information, obtain production quantity by the number of this information in specified time limit is counted.
In addition, above-mentioned " flow chart customizing messages ", the identifying information (identifying information so long as ID and other information that can discern by the device that carries out data processing get final product) of for example representing all classification of making flow chart etc. of sewing machine, for example, in various identifications of making batch to be under the situation of unit management operation, as long as comprise the information that can discern each batch.
The effect of invention
The operation analysis apparatus of the invention of technical scheme 1 record, by obtaining the charge book data, and, which operator needing in which flow chart and this flow chart to carry out how many operation required times to gather to by operator's customizing messages, flow chart customizing messages and operation required time customizing messages that the utilization of operation required time computing unit comprises in the charge book data.
And, the actual job time calculating unit, for each operator, the operation required time that this operator is carried out the flow chart of operation adds up to, and carries out the calculating of actual job time.
Then, in a plurality of charge book data that gather, exist by a plurality of operators and divide the work under the situation of the flow chart that operation carries out, for this flow chart, with each operator's operation required time based on harmonic average and equalization.
For example, be that t1, t2, t3 carry out under the situation of same flow chart with the operation required time respectively at operator A, B, C, according to the notion of harmonic average, its mean value is calculated by ta=3/ ((1/t1)+(1/t2)+(1/t3)).Because this value just in time is equivalent to carry out 3 times of required time under the situation of described flow chart jointly at operator A, B, C, carries out the needed operation required time of this flow chart so can become the operator of the average ability with operator A, B, C.
As mentioned above, even share by a plurality of operators making whole flow charts, wherein Yi Bufen flow chart contains under the situation of common operation, owing to make operation required time equalization by the method that reflects each operator's work capacity, so in order to make under the situation that each operator's actual job time and work capacity are impartial as far as possible accordingly and adjust, can more meet the destination and calculate the actual job time, by using as operation analysis apparatus of the present invention, can correctly adjust operator's process distribution, realize the raising of production efficiency.
The invention of technical scheme 2 records, be the information of production quantity information that in the charge book data, comprises each flow chart of each operator, a flow chart is divided the work the situation of operation by a plurality of operators under, the actual job time calculating unit, when the calculating of actual job time of each operator, operation required time for the flow chart that carries out jointly, be not with the value of equalization by harmonic average directly and the operation required time of other flow chart add up to, but on the operation required time after harmonic averageization, multiply by an operator's the production quantity production quantity proportion all with respect to common operation, on this basis, the operation required time of flow chart with other adds up to and the computational tasks required time.
The notion of actual job time is, in all required whole required times of the operation of being made up of whole flow charts, the time scale that each individual of operator is shared quantizes.
On the other hand, for the flow chart that carries out operation jointly,, do not carry out operation with other operation equal number owing to be not to carry out an operation integral body by independent operator, so in the calculating of actual job, can not carry out additive operation in the same manner with other operation.Thus, shown in above-mentioned actual job time calculating unit, multiply by the operation required time by the production quantity of the operator being carried out operation separately with respect to all quantity proportions, can reflect the time scale that operator individual shared in all whole required times of operation more reliably.
Thus, the operation analysis apparatus of the application of the invention can be obtained the actual job time more reliably, correctly adjusts operator's process distribution, can realize the raising of production efficiency.

(key frame)
In operation analysis apparatus 101, make operation data D constantly if obtain from each production management sewing machine 10, then, key frame M1 is presented on the display 103 by the predetermined process program.In Fig. 5, key frame M1 is the demonstration of complete list form, it is illustrated in from making the operation moment data D that each production management sewing machine 10 obtains, and whether the data of (time on date) exist during belonging to certain identifying information (operator ID and operation ID) and being in certain.In this key frame M1, the identifying information of guide look display operation person ID and operation ID on the longitudinal axis, they become the selector switch of ID simultaneously, during showing according to time series on the transverse axis, the selector switch during they become simultaneously.In addition, the Show Color of the cell that exists at the cell that begins from ID arbitrarily to arrange with horizontal row, with position that the cell that beginning during is arbitrarily arranged with vertical row is reported to the leadship after accomplishing a task mutually, whether expression exists data in ID arbitrarily is during any.
In addition,, can be chosen among longitudinal axis display operation person ID and the operation ID which, by assigned switch M12 during showing being operated the operation of the indication range during can carrying out by mouse by change-over switch M11 being operated by mouse.
And key frame M1 works as " selected cell ", that is, and and in order to be selected to the data of the object that the demonstration of carrying out recorded content or form show, during some in selecting during identifying information and the data recording (time on date).Promptly, as mentioned above, show that the longitudinal axis represents that ID, transverse axis represent the chequer on date, because grid cell separately becomes selector switch, so by respectively they being selected by mouse action, thereby, specify and be extracted in the data that the selected time on date obtained for selecteed ID.
Based on Fig. 6, the processing that CPU 105 carries out in above-mentioned key frame M1 is described.Here, be that example describes with the situation of on the longitudinal axis, having selected operator ID.
At first, illustrate when key frame M1 shows, to the processing of carrying out color differentiating and showing that has or not of each ID and the data during each.
This processing, at first, with make operation constantly data D begin to read in (step S21) from the prostatitis of data ordering, whether the record of judging first operator ID exists (step S22), under the situation of the record of finding operator ID, the nearest operation time information (step S23) of making that is positioned at its rear is compared in search with this operator ID, make the time on date (step S24) of sense data record the operation time information from this.By in the gamut of respectively making operation moment data D, carrying out this operation (step S25), can obtain whole record dates and the time of first operator ID.By the operator ID after it is carried out identical processing, can determine whether to exist the charge book data to each operator ID, each time on date, thus, the color differentiating of carrying out each cell shows control.
In addition, selecting in the processing of above-mentioned steps S22, to judge whether to exist operation ID under the situation of operation ID on the longitudinal axis by change-over switch M11.
Below, based on Fig. 7, the processing that CPU 105 is carried out is described under the situation that key frame M1 works as selected cell.Here, be that example describes with the situation of on the longitudinal axis, having selected operator ID.
In the show state of key frame M1, CPU 105 has judged whether to select the some operator ID (step S31) on the longitudinal axis, has judged whether then to select (step S32) during some on the transverse axis.And, judge whether to have selected operator ID and during the two (step S33).
Its result, under the situation that both all select, CPU 105 is for the data (step S34) of making operation data D constantly, extracting the person ID that belongs to the selection operation.The method of extracting is, begins to carry out reading of data, search operaqtion person ID in the prostatitis of data D constantly from making operation.If detect operator ID, judge then whether this operator ID is selecteed operator ID, only under the situation of its person ID that is the selection operation, extract data and record till next operator ID.In the gamut of rotary speed data D1, carry out detection, judgement, the data extract of operator ID, all data that extract are stored among the RAM 106 as temporary transient extraction data.
Then, if carried out the extraction of temporary transient extraction data, then for these temporary transient data of extracting, CPU 105 belongs to the extraction (step S35) of the extraction data during the selection.
The method of extracting is, begin to read from this temporary transient prostatitis of extracting data and respectively make operation data constantly, judge the represented moment of each data whether be in selected during in, extract under the situation in only during being in, be recorded among the RAM 106, carry out this operation for the gamut of temporary transient extraction data.Thus, for making operation data D constantly, extract with selected operator ID and suitable extraction data during selecting.
In addition, selecting on the longitudinal axis under the situation of operation ID by change-over switch M11, CPU 105 judges whether selected operation ID in the processing of above-mentioned steps S31, extracts to belong to the temporary transient extraction data of selecting operation ID in the processing of step S34.
And, operator ID or operation ID and during selection certainly be a plurality of.And in this case, the extraction of temporarily extracting data and extracting data is selected to carry out respectively during ID and each for each.
(operation complete list [1])
In each display frame, have and carry out tag switches M13～M16 that display category is switched,, can switch display category by they are carried out mouse action.In addition, here, below the shown operational situation monitor of the M14 relevant with the present invention is described.Display category is being switched under the situation of operational situation monitor by above-mentioned tag switches M14, on display 103, can show operation complete list picture M2 shown in Figure 8.
This operation complete list picture M2 is to be the picture of benchmark with operation ID, show operation ID at left column, adjacent right row display operation person ID at this operation ID, the adjacent right average productive temp time (1) that is listed as demonstration as the operation required time at this operator ID, be listed as the average productive temp time (2) that shows as the operation required time on the adjacent right side of this average productive temp time (1).In addition, in this operation complete list picture M2, projects are arranged explicitly along horizontal row and are shown, promptly, the ID that shows the operator who carries out the represented flow chart of this operation ID at the adjacent right row of each operation ID, the average productive temp time (1) when the right side of this operator ID shows that this operator carries out this flow chart is in the average productive temp time (2) of the right side of this average productive temp time (1) demonstration based on the average productive temp time (1).
Here, the so-called average productive temp time (1), be with second [s] be unit, represent that each operator makes mean value of making the productive temp time (operation required time) of thing of production in the operation at each.This average productive temp time (1), make operation constantly in the scope of the extraction data of data D above-mentioned, calculate according to the operation mistiming constantly of making of front and back.
That is, the CPU 105 of operation analysis apparatus 101 averages the calculating of productive temp time (1) by utilizing said method, thereby works as " operation required time computing unit ".
And, as by same operator to so many situations of making of same flow chart, in extracting data, there be identical a plurality of the making under the operation situation constantly of operator and flow chart, by all make operation total constantly divided by making number of times with these, equalization averages the calculating of productive temp time (1) by addition is average.
The average productive temp time (2) calculated based on the average productive temp time (1), was used for the calculating of actual job time described later.
This average productive temp time (2) is unit representation with second [s] also, it is in the scope of extracting data, the division of labor operation determination processing that utilization is undertaken by CPU 105, whether judgement carries out operation by a plurality of operators for a flow chart, be judged as negative, judge that promptly a flow chart is only undertaken under the situation of operation by an operator, according to the average productive temp time (1)=on average the productive temp time (2) calculates, be judged as certainly, judge that promptly a flow chart divided the work under the situation of operation by a plurality of operators, each operator's the average productive temp time (1) is continued by harmonic average equalization, calculate.
Specifically, operation (45) in operation complete list picture M2 is by operator (1067), (1105), (1106) division of labor operation, in this case, with each individual's the average productive temp time (1) is 85[s], 103[s], 69[s] equalization according to the notion of harmonic average, calculate this mean value and be
Because this value just in time is equivalent to 3 times of required time 1/ ((1/85)+(1/103)+(1/69)) [s] under the situation of being carried out described flow chart by operator (1067), (1105), (1106) jointly, carries out the required operation required time of this flow chart so this value can be called the operator of the average ability with operator (1067), (1105), (1106).
That is, the CPU 105 of operation analysis apparatus 101 averages the calculating of productive temp time (2) by said method, thereby acts on as " the operation required time computing unit " of this operation analysis apparatus 101.
In Fig. 9, during CPU 105 selects at each selection operation person ID and each, for from making the extraction data that operation is extracted the data D constantly, begin to read in (step S41) from prostatitis.
And, the process that begins to read in from the prostatitis of extracting data, carry out the detection of operation ID and operator ID, and, poor according to the surrounding time of making operation moment data related with it, calculating in order and making required time is productive temp time (step S42).
Then, carry out removing the time processing (step S43) of deviation value from the productive temp that calculates in order.
Be described in detail the above-mentioned deviation value of removal that CPU 105 carries out and an example of the processing of calculating mean value here.
At first, in extracting the scope of data, at the set of identical a plurality of productive temp time of each operator ID and operation ID and basis of calculation deviation S.Standard deviation S is calculated based on following formula (1)～(3).That is,, calculate the mean value of productive temp time to each above-mentioned scope.Here, symbol x represents to become each productive temp time of object range, and the x that has line represents its mean value.In addition, symbol n is the sample number that becomes the productive temp time of object range.
And,, from the mean value of obtaining, calculate square deviation s based on following formula (2)
2, based on following formula (3), by its square root basis of calculation deviation s.
[several 1]
Then, calculate the mean value of 3 σ scopes according to standard deviation s.
That is, obtain+3 σ=(mean value of x)+(s * 3) and-3 σ=(mean value of x)-(s * 3), only extract the productive temp time in ± 3 σ scopes (more than or equal to-3 σ and be less than or equal to+3 σ), remove deviation value.
Then, average by addition, to each productive temp time the averaging processing once more in each scope behind the removal deviation value, to each range computation average productive temp time (1) (step S44).
Then, calculate the processing (step S45) of average productive temp time (2).
This equalization is handled shown in the process flow diagram of Figure 10, at first, judges whether to divide the work operation (division of labor operation determination processing) (step S451) by a plurality of operators for certain flow chart.
That is, will extract data, judge whether there are a plurality of operators that belong to each operation according to each operation classification.Only exist under an operator's the situation for an operation, the value that belongs to the average productive temp time (1) of this operation directly becomes the average productive temp time (2) (step S452).
In addition, exist under a plurality of operators' the situation for an operation, will belong to each operator's of this operation the value of average productive temp time (1), the equalization by harmonic average is calculated the average productive temp time (2) (step S453).
If obtain the average productive temp time (2) for all process steps that extracts data, then CPU 105 calculates the addition mean value of the average productive temp time (2) in all process steps.And, multiply by the regulation ratio by this compound average, calculating upper limit value (=mean value ÷ 0.85) and lower limit (=mean value * 2-higher limit) (step S46).
Then, carry out the demonstration of described operation complete list picture M2, perhaps carry out the demonstration (step S47) of graphic presentation picture M3.Under the situation of the demonstration of carrying out graphic presentation picture M3, as shown in figure 11, mark and draw the value of the average productive temp time (2) of each operation, carry out broken line graphic presentation, simultaneously, the mean value line M31 and the higher limit line M32 of higher limit, the lower limit line M33 of lower limit that in this graphics display area, show comprehensive mean value.Thus, by when showing the figure of average productive temp time (2), each line M31 and M32 of showing higher limit and lower limit simultaneously, the supvr who makes operation as standard, can easily judge the degree of fluctuation of the average productive temp time (2) of each operation with each line M31 of this higher limit and lower limit and M32.
The switching of table and figure is undertaken by the Shape Display Toggle M22 in the picture is carried out mouse action.
(operation complete list [2])
Operation complete list picture M2 is to be the picture of benchmark with operation ID as mentioned above, and change-over switch M21 is set, and it will be that to switch to operator ID be benchmark to benchmark with operation ID.That is, if this change-over switch of mouse action M21, then as shown in figure 12, it is the operation complete list picture M4 of benchmark that demonstration is switched to operator ID.
In this operation complete list picture M4, at left column display operation person ID, show operation ID in the right side of this operator ID adjacent column, show production quantity in the right side of this operation ID adjacent column, show the average productive temp time (2) in the right side of this production quantity adjacent column, show the actual job time in the right side of this average productive temp time (2) adjacent column.And, in operation complete list picture M4, projects are arranged demonstration explicitly along horizontal row, promptly, right side at each operator ID, show that this operator carries out the operation ID of the flow chart of operation, right side at this operation ID, show that this operator carries out the production quantity of this flow chart, right side in this production quantity, show the average productive temp time (2) when this operator carries out this flow chart,, show the actual job time based on the average productive temp time (2) on the right side of this average productive temp time (2).
Here, as the actual job time, in principle, be by with described make operation constantly the represented whole flow chart of operation ID in the extraction data area of data D distribute to each operator, the average productive temp time (2) that will belong to each operator's flow chart adds up to and calculates.
But, divide the work by a plurality of operators under the situation of flow chart of operation existing, shown in area B, for dividing the work the operator of operation, with the production number of packages with this operator on duty of average productive temp time (2) ratio with respect to whole production numbers of packages of this flow chart, on this basis, add up to, calculate the actual job time with other average productive temp time (2) of each flow chart.
As mentioned above, operation (45) is by operator (1067), (1105), (1106) division of labor operation, if with operator (1105) is that example describes, then this operator (1105) is approximately 83[s the average productive temp time (2) in operation (45)] (with reference to Fig. 8), but whole production quantities of operation (45) are 5+15+10=30, wherein, because operator's (1105) production quantity is 5, so at 83[s] on multiply by 5/30, become
Thus, operator's (1105) the actual job time, add up to by the average productive temp time (2) the flow chart of above-mentioned value and other, calculate be 88+194+72+14=368[s].
That is, the CPU 105 of operation analysis apparatus 101 by carrying out the calculating of actual job time by said method, works as " actual job time calculating unit ".
In Figure 13, CPU 105, at each selection operation person ID and during selecting, to from making the extraction data that operation is extracted the data D constantly, begin to read in (step S51) from prostatitis.
Then, the process that begins to read in from the prostatitis of extracting data, carry out the detection of operation ID and operator ID, and, make operation the surrounding time of data is poor constantly according to related with it, calculating in order and making required time is the productive temp time.And, the number of making operation moment data that operation is consistent with the operator is counted, calculate production quantity (step S52).
Then, carry out the processing (step S53) of removing deviation value the time from the productive temp of calculating in order.The method of removing deviation value is identical with described step S43.
Then, average by addition on the basis of having removed deviation value, with each productive temp time averaging processing once more of each scope of operator and operation unanimity, for each range computation average productive temp time (1) (step S54).
Then, average the computing (step S55) of productive temp time (2) and actual job time.
This is handled, shown in the process flow diagram of Figure 14, with step S451 in the same manner, judge whether to be divided the work operation (division of labor operation determination processing) (step S551) for some operations by a plurality of operators.
And, not divide the work under the situation of operation, the value of average productive temp time (1) that will belong to this operation is directly as the average productive temp time (2) (step S552).
In addition,,, will belong to each operator's of this operation the value equalization of average productive temp time (1), calculate the average productive temp time (2) (step S553) by harmonic averageization dividing the work under the situation of operation.
And,, on the value of the average productive temp time (2) that calculates, multiply by each operator's production quantity ratio (production quantity that production quantity/operation of operator individual is all) (step S554) for dividing the work each operator of operation.
And at each operator, the average productive temp time (2) of each operator being carried out the operation of operation adds up to calculating.At this moment, for dividing the work average productive temp time (2) of operation of operation, as mentioned above, add up to (step S555) with multiply by the value that obtains after the production quantity ratio.Handle the actual job time of calculating each operator by this.
If the whole operators for extracting data obtain the actual job time, then CPU105 calculates the addition mean value of whole operators' actual job time.And, multiply by the regulation ratio by this compound average, calculating upper limit value (=mean value ÷ 0.85) and lower limit (=mean value * 2-higher limit) (step S56).
Then, carry out the demonstration of described operation complete list picture M4, perhaps carry out the demonstration (step S57) of graphic presentation picture M5.Under the situation of display graphics display frame M5, as shown in figure 15, mark and draw the value of each operator's actual job time, carry out broken line graphic presentation, simultaneously, the mean value line M51 and the higher limit line M52 of higher limit, the lower limit line M53 of lower limit that in this graphics display area, show comprehensive mean value.As mentioned above, by when the graphic presentation of actual job time, each line M51 and M52 of showing higher limit and lower limit simultaneously, the supvr who makes operation is a standard with each the line M51 and the M52 of this higher limit and lower limit, can easily judge the degree of fluctuation of actual job time.
In this case, also can show switching by the Shape Display Toggle M22 in the picture is carried out mouse action with figure.
