- This process is actually a process of prompting data transmission of the corresponding net processing time T2 and receiving data by designating the process code and the manufacturing number to the progress server 30.
- the progress server 30 may notify the support tool execution server 50 that the net processing time T2 does not exist.
- the process of step S112 constitutes an input result acquisition unit in the present embodiment. The situation in which the net processing time T2 does not exist occurs when at least one of the input associated with the completion of the setup corresponding to the designated process code and manufacturing number and the input associated with the completion of the processing are not performed.
- the threshold value Tth2 is set to be equal to or longer than the minimum time assumed as the machining time (for example, “1 minute”). This process is for judging whether or not the input accompanying the completion of the setup and the input accompanying the completion of the machining have been performed as expected. That is, when an input to that effect is made upon completion of the setup and an input to that effect is made upon completion of the machining operation, the time interval between these two inputs is the time required for the machining operation.
- the time required for the machining work is considered to be within a certain range even if individual differences among workers are taken into account, if the above time interval is excessively short, it is made at the timing when the input should be made. It is not considered. Specifically, for example, the case where the input made upon completion of the machining is made after the input made upon completion of the setup, and the actual machining work is performed thereafter, and the like.
- step S114 If an affirmative determination is made in step S114, the symbol O is added to the input result for the setup completion and processing completion in the designated process code and manufacturing number in step S116.
- step S118 the symbol I is given to the input result regarding the setup completion and processing completion related to the designated process code and manufacturing number.
- the symbol I is given when an expected input is made, and the symbol O is given when an expected input is not made.
- the processing in steps S114 to S118 constitutes a determination unit in the present embodiment. Incidentally, if the net processing time T2 cannot be acquired in step S112, an affirmative determination may be made in step S114, and the symbol O may be given to the input result for the setup completion and processing completion for the designated process code and manufacturing number.
- step S120 With respect to the process code specified in step S100, it is determined whether or not the processes in steps S104 to S118 have been completed for all manufacturing numbers. If a negative determination is made in step S120, the process returns to step S102. On the other hand, when a positive determination is made in step S120, the process proceeds to step S122. In step S122, it is determined whether or not the processing in steps S102 to S120 has been completed for all process codes. If a negative determination is made in step S122, the process returns to step S100, assuming that there is still a process for determining whether or not the input has been performed as expected.

- This process constitutes a collection calculation means in the present embodiment.
- step S126 the calculation processing result is visually notified (displayed) using the display 52 shown in FIG. This processing constitutes notification means in the present embodiment.
- the judgment result of whether each of the input set accompanying the start of setup and the input accompanying the completion of the setup and the input set accompanying the completion of the setup and the input accompanying the completion of the processing has been made as expected is As a comprehensive judgment (setup processing pattern) that combines the two, a vector notation composed of two components is used as illustrated in FIG.
- the net setup mark indicates the judgment result regarding the input (net setup time) associated with the input at the start of setup and the setup completion (net setup time), and the net process mark indicates the input and process at the completion of setup.
- the judgment result regarding the set (net processing time) of the input accompanying completion is shown.
- Each of the net setup mark and the net processing mark is the first component and the second component of the vector in the notation of the setup processing pattern.
- FIG. 10 shows a display example of the display 52.
- the above ratio is indicated for each department (A ** 1, A ** 2) that performs several processes.
- the process code ⁇ *** 1, ⁇ *** 2,... ⁇ ** 11 is executed by the department A ** 1, and the process codes ⁇ *** 2,.
- the department A ** 2 executes *** 9.
- FIG. 11 shows a procedure of processing executed by the support tool execution server 50 in the present embodiment. This process is repeatedly executed, for example, every predetermined period (for example, 24 hours).
- step S130 the symbols representing the process codes are appropriately ranked and arranged in order from the highest order, and then the corresponding manufacturing numbers are ordered in order from the earliest setup start date and time. Execute the process of arranging. For each serial number, the process codes are the same if they are arranged in order from the earliest setup start date and time and the same setup start date and time and different process codes.
- This is a process for ensuring that things are in an adjacent arrangement. This process is performed by designating a process code to the factory performance collection PC 20 via the progress server 30 to prompt data transmission of the setup start date and serial number corresponding to each process code and receiving the data. Is called. In this embodiment, this process constitutes an input result acquisition unit.
- step S132 two adjacent production numbers having the same process code in the arrangement are selected.
- step S134 setup start dates and times t1 and t2 relating to the pair of serial numbers selected in step S132 are acquired.
- step S136 it is determined whether or not the absolute value of the time difference between the pair of setup start dates and times t1 and t2 is less than the threshold value tth.
- This process is for determining whether or not the input accompanying the start of setup has been made as expected. That is, with respect to a processing object or a processing object group (lot) specified by a certain manufacturing number, after performing an adjustment operation, a processing operation is performed, and when this is completed, the processing object specified by another manufacturing number or It is assumed that an adjustment operation and a processing operation are performed on the processing object group (lot).
- step S136 If an affirmative determination is made in step S136, the symbol O is added to the input result for the start of setup for the designated process code and pair of manufacturing numbers in step S138.
- step S140 the symbol I is given to the input result associated with the start of setup for the designated process code and the pair of manufacturing numbers.
- the symbol I is given when an expected input is made, and the symbol O is given when an expected input is not made. Note that the processing in steps S136 to S140 constitutes determination means in the present embodiment.
- step S142 it is determined whether or not the processing in steps S134 to S140 has been completed for all pairs of adjacent manufacturing numbers in the array in step S130. If a negative determination is made in step S142, the process returns to step S132. On the other hand, when a positive determination is made in step S142, the process proceeds to step S144.

- This process constitutes a collection calculation means in the present embodiment.
- the calculation processing result is visually notified (displayed) using the display 52 shown in FIG.
- the number of symbols O may be described for each process code.

- an input result associated with the start of the adjustment work, an input result associated with the completion of the adjustment work, an input result associated with the start of the work to be processed, and an input result associated with the completion of the work to be processed may be included.
- the symbol O may be given as an unexpected input even when the net setup time T1 and the net processing time T2 are excessively long.
- the time outside the work time should be deducted. This is because, for example, in the progress server 30 or the like, information on the work time is stored as data, and a determination process for determining whether or not the dates are different between the setup start date and time and the setup completion date and time. This can be realized by performing the above deduction processing.
- the symbol I is used when the input is performed as expected, and the symbol O is used when the input is not performed as expected. Absent.
- the determination result of the determination means may be ternary. This can be realized, for example, based on a comparison between the net processing time and two threshold values that are different from each other, with the judgment of unexpected, gray, as expected in order from the shortest time. .
- the ratio of what was performed as expected to the population (the sum of what was performed as expected and what was not performed as expected)
- the ratio of each type (IIO, IOI, etc.) for (III, II) and those not performed as expected was calculated, this is not restrictive. For example, you may calculate only the ratio of what was performed as expected. Further, for example, only the ratio for each type of items that are not performed as expected may be calculated. Further, for example, in the first embodiment (FIG. 7), the ratio of “IIO”, “IOI”, “IOO”, “OII”, “OIO”, “OOI” with respect to all parameters is calculated. It may be. However, the processing is not limited to the processing for calculating the ratio.

以下、第2の実施形態について、先の第1の実施形態との相違点を中心に図面を参照しつつ説明する。なお、第2の実施形態において、第1の実施形態と同一の構成については、同一の符号を付してその説明を省略する。
以下、第3の実施形態について、先の第1の実施形態との相違点を中心に図面を参照しつつ説明する。なお、第3の実施形態において、第1の実施形態と同一の構成については、同一の符号を付してその説明を省略する。
<その他の実施形態>
以上、実施の形態に基づき本発明を説明したが、本発明は上記実施の形態に何ら限定されるものではなく、本発明の趣旨を逸脱しない範囲内で種々の改良変形が可能であることは容易に推察できるものである。以下、変形例を例示列挙する。
調整作業の開始に伴う入力結果、調整作業の完了に伴う入力結果、および加工する作業の完了に伴う入力結果からなるものに限らない。たとえば、調整作業の開始に伴う入力結果、調整作業の完了に伴う入力結果、加工する作業の開始に伴う入力結果、および加工する作業の完了に伴う入力結果からなるものであってもよい。
たとえば、上記第1の実施形態(図5)の処理と、第2の実施形態(図8)の処理とを併せ行ってもよく、また、さらに第3の実施形態(図11)の処理を併せ行ってもよい。
上記第1の実施形態(図7)や第2の実施形態(図10)では、母数(想定通り行われたもの、および想定通り行われなかったものの和)に対する想定通り行われたものの割合(III、II)や、想定通り行われなかったものについての種類毎(IIO,IOI等)の割合を算出したが、これに限らない。例えば、想定通り行われたものの割合のみを算出してもよい。また、例えば、想定通り行われなかったものについての種類毎の割合のみを算出してもよい。さらに、例えば、上記第1の実施形態(図7)において、「IIO」,「IOI」,「IOO」,「OII」,「OIO」,「OOI」の全ての母数に対する割合を算出するものであってもよい。もっとも割合を算出する処理を行うものにも限らない。たとえば、想定通り行われなかったものの所定期間における総数を算出する処理を行うものであってもよい。
上記実施形態では、支援ツール実行サーバ50を入力結果の取得手段としたが、これに限らない。たとえば、進捗サーバ30および支援ツール実行サーバ50を1つのハードウェア手段とし、これによって取得手段を構成してもよい。また、たとえば、工場実績収集PC20、進捗サーバ30および支援ツール実行サーバ50を1つのハードウェア手段とし、これによって取得手段を構成してもよい。もっとも、支援ツール実行サーバ50の機能を備えるハードウェア手段が取得手段を構成すること自体必須ではない。たとえば、先の図1に示した構成において、工場実績収集PC20を取得手段とみなすこともできる。
異種類の作業に関する判断結果を合わせて表示しないものとしては、上記第3の実施形態において例示したものに限らない。たとえば、先の図7に示した表示に代えて、段取開始に関する判断結果、段取完了に関する判断結果、および加工完了に関する判断結果のそれぞれを、各別の表に表現して表示してもよい。この際、たとえば、段取開始に関する判断結果の表示を希望するか、段取完了に関する判断結果の表示を希望するか、加工完了に関する判断結果の表示を希望するかをユーザが指示可能とすることで、指示に応じて画面を切り替えることができるようにすれば、全ての情報を通知することができる。
上記実施形態(図2)では、段取開始に伴う入力に限って、工程コードを読み込んだがこれに限らない。たとえば段取完了に伴う入力および加工完了に伴う入力についても製造番号のみならず工程コードを読み込むようにしてもよい。この場合、入力処理後にエラー通知に基づき人が入力データを一部手作業で修正することがなくても、段取開始に伴う入力のみが抜けたデータ(OII,OIO,OOI)が生じうる。
入力情報を有する手段としては、1次元コードに限らず、たとえば2次元コードであってもよい。
たとえば、ハンディターミナル10に、段取開始に伴う入力がなされてから段取完了に伴う入力がなされるまでの時間と閾値との大小比較をする手段と、閾値の方が大きい場合、入力が適切でない旨を警報音等によって通知する手段とを搭載してもよい。この場合、大小比較する手段が判断手段を構成し、警報音等を発する手段が通知手段を構成する。
入力データについて不整合にかかわらず、それらを人が手作業で修正することが可能な設定としなくてもよい。また、不整合については、自動的に推論補正する演算処理手段を搭載してもよい。
