Abstract

PROBLEM TO BE SOLVED: To automate the management of designing operation by determining a document data amount-generation time curve (master curve), gathering the amount of data on documents in operation and comparing the curve showing the data amount and generation time with the master curve, and calculating and displaying progress. SOLUTION: A CAD terminal 102 is equipped with a keyboard and a CRT and a designer performs plotting operation on the CAD terminal 102. A processor 101 derives the skillfulness of the designer in a skillfulness database 104 according to a design code that the designer inputs. The processor selects the master curve showing the CAD data amount and plotting time of a drawing that the designer will plot in a master curve database 103 according to the skillfulness, drawing size, drawing kind, and difficulty. While the plotting is carried on, the processor 101 monitors the CAD data amount to decide whether the progress is fast or slow, calculate a delay or leading time, displays measures against delay, correct the difficulty, and improve the precision of the master curve.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work progress management method in a design work in which a computer is used to perform work such as drawing and technical data preparation. The progress management and load management and schedule management developed based on the data It can be used for

[0002]

2. Description of the Related Art In the conventional design work, the creator estimates the progress of the work by himself, applies for the completion time, and reports the progress status at his own discretion. Therefore, the margin for the target becomes large and the accuracy of the data is limited because the criteria for evaluating the results are not constant. For this reason, the management standard is a comprehensive one obtained from the actual results, for example, the required man-hour is half a day / sheet in A3 conversion, and the progress is proportional to the elapsed time.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to quantitatively and sequentially automate the progress of design work, which is the basis of design work management, that is, design load management and schedule management. The objective is to accurately capture without the designer's hand.

[0004]

First, a master curve of a document data amount-creation time curve corresponding to the size and type of a document, the difficulty of preparation, and the proficiency of the creator is created. here,
The creator inputs only the document size, type, and difficulty level, and the master curve corresponding to the four conditions is automatically selected by adding the proficiency level of the creator. During the work, the slow speed judgment, calculation of the slow speed time, and presentation of the delay recovery measure are always performed by collating the document data amount corresponding to the elapsed time with the master curve.
Here, as the document data amount, physically measurable data such as the number of input characters, the number of pixels, the number of graphic objects, and the capacity of a file when stored is used. Then, a master curve that matches the current document data amount is searched, presented as a new master curve, replaced, and the difficulty level is corrected.
At the end of creation, the amount of document data is selected and stored, the master curve correction calculation is performed, the actual value of the document data amount-creation time curve is stored, and the master curve is corrected according to the actual result. In this way, the master curve is constantly rewritten during the design work, so the accuracy of the master curve can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A drawing operation by CAD will be described as an embodiment of the present invention with reference to the drawings. FIG. 1 is a block diagram showing an embodiment for managing the progress of design work according to the present invention.

The embodiment shown in FIG. 1 comprises a processor 101, a CAD terminal 102, a master curve database 103, and a proficiency level database 104. The CAD terminal 102 has a keyboard and a CRT, and the designer draws with the CAD terminal 102. Processor 101 from the designer code entered by the designer
Thus, the proficiency level of the designer of the proficiency level database 104 is derived. Based on this proficiency level and the drawing size, drawing type, and difficulty level input by the designer, the processor can use the master curve database 103 to determine the drawing to be drawn from the master curve database 103.
A master curve showing the amount of CAD data-drawing time is selected. While the drawing is in progress, the amount of CAD data is monitored by the processing device 101, and slow speed judgment, slow speed calculation, delay recovery measures are presented, difficulty is corrected, master curve accuracy is improved, and so on.

In this embodiment, the master curve database 103
The master curve data shown in FIG. here,
The master curve refers to the reference curve that is the target of comparison with the curve showing the relationship between the work time of the worker and the work data amount.This reference curve is registered in multiples and any master curve can be selected for comparison. You can select and compare. Drawing type 20
1 indicates the type of drawing created on the CAD terminal,
The master curve data is created corresponding to the drawing type 201. The pattern 202 shows a pattern of a graph showing the relationship between the CAD data amount-working time of the plotting time curve and the CAD data amount, and the data of the CAD data amount 205 for each of the difficulty level 203 and the drawing size 204 corresponding to these patterns. Is recorded. As a result, a CAD data amount-drawing time curve having a specific pattern is determined for each drawing type, difficulty level, and drawing size.

The CAD data amount-drafting time curve referred to here is a curve showing a pattern in which the vertical axis represents the CAD data amount and the horizontal axis represents the plotting time, and the curve shows the time transition of the CAD data amount.

FIG. 3 shows data stored in the proficiency level database 104. As in the example, the proficiency level 301 and the proficiency level 302 are stored for each designer. Based on this data, a master curve according to the operator is selected.

Next, the processing procedure of the present invention will be described with reference to the flowchart of FIG.

When the designer inputs a designer code at the start of drawing, the processor 101 extracts the designer's proficiency from the proficiency database 104 (step 1001). The designer has the drawing size,
When the drawing type and the degree of difficulty are entered, the processor 101 selects the corresponding master curve, multiplies the drawing time on the horizontal axis of the curve by the proficiency coefficient, and indicates the relationship between the CAD data amount and the drawing time, which is the standard of the progress. Identify the reference curve (steps 1002, 10
03). FIG. 4 shows the relationship between the master curve and the progress standard curve.
The master curve obtained from FIG.
The progress reference curve (1) or (2) is obtained by adding the proficiency counts, and this progress reference curve is used as a curve when actually comparing the progresses.

During the drawing of the CAD drawing by the designer, the processing device 1
By 01, the CAD data amount of the progress reference curve corresponding to the elapsed time is compared with the actual data amount, the slow speed is judged and the slow time is calculated (steps 1004, 1005). FIG. 5 is a diagram showing this relationship, in which the progress standard curve is the curve obtained in FIG.
The actual data amount is a curve indicating the work that the work is performing.
Here, the actual data amount is the curve when the work is ahead of the reference, and the actual data amount is the case when the work is behind.

When the work is delayed, as shown in FIG. 6, the completion time is calculated from the current data amount according to the master curve, and the progress degree 601 (advance time, delay time, completion time delay time), The delay recovery measure 602 (required remaining time, drawing speed-up ratio, etc.) is displayed (step 1007).

When the current data amount is different from the value of the progress standard curve, it is searched whether or not there is another progress standard curve with which the current data amount matches under the same drawing size, drawing type and proficiency level (step 1008). ). In this case, the master curve is used to search for master curves with different difficulty levels. However, for each curve of difficulty level, the width specified before and after is set. The curve of is used. FIG. 7 shows the relationship between curves having different degrees of difficulty. here,
If the curve of the actual data amount falls within the "defined width" in the figure, the curve of the actual data is set as the standard curve of the progress using the curve of the difficulty level C as the master curve. Similarly, if a predetermined width is provided for the difficulty levels A and B, the curve of the difficulty level to be used can be selected.

As a result, as shown in FIG. 8, there is a new master curve indicating the presence / absence of another progress reference curve, and whether there is a new master curve or not is displayed as a new master curve. (Step 1009). When the designer gives a replacement instruction, similar comparison and monitoring is continued thereafter by the newness degree standard curve obtained from the new master curve (step 1010). It is displayed that there is no new master curve (step 1012).

If the CAD data at the time of completion of drawing and the time value are within a certain variation range with respect to the progress standard curve, this data is stored for correcting the master curve data, excluding the learning coefficient. When a fixed number of correction data are collected, a representative value is calculated from the occurrence frequency distribution, and this is used as a new master curve (step 1011). FIG. 9 shows the relationship between the master curve and the actual data curve stored as correction data.

When the work is completed, a message asking whether to save the data is displayed (step 101
4) If so, save the data (step 101)
Five). Then, an inquiry is made as to whether or not the master curve is to be corrected (step 1016). When the master curve is to be corrected, the master curve is corrected and the CAD is completed (step 1017).

In the present embodiment, the case of the CAD drawing work is explained. However, if the drawing is replaced with a general material and the drawing work is replaced with the material creating work, the present invention is not limited to the CAD drawing work. It is clear that it is also effective in preparing various materials.

[0019]

According to the present invention, the progress of design can be quantitatively grasped in real time without human sense, and the progress can be controlled by displaying it on the screen during drawing or on various progress management charts. , Load management, schedule management, etc. can be performed quantitatively and with high accuracy. Also, as the master curve is updated and changed as the actual work is repeated,
There is an effect that a more accurate master curve can be obtained.
