Abstract

<P>PROBLEM TO BE SOLVED: To manage progress circumstances under the consideration of the difficulty of a design in each phase of a design operation. <P>SOLUTION: A graph 100 represents a correlation between the operation time of a design operation and the progress rate. In the graph 100, a CAD operation is not much advanced with respect to the operation time since layout or a new mechanism are considered in a phase 1, and the CAD operation is advanced at a stretch, and the progress rate is sharply increased according to this in a phase 2, and since check or correction prior to drafting is time-consuming, the speed of the CAD operation is slowed down, and the increase of the number of features is relaxed in a phase 3. Thus, the progress rate of the design operation is not simply increased according to the lapse of the operation time but increased according to the difficulty of design in each phase. Therefore, it is possible to manage the progress circumstances under the consideration of the difficulty of design in each phase of the design operation by changing the gradient of the progress rate with respect to the operation time in each phase. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a technique for managing the progress of work, and more particularly to a technique for managing the progress of design work related to CAD (Computer Aided Design) drawings.

  In product development, in order to prevent rework of the design, the manager's management terminal grasps the progress of the design work by each designer and gives appropriate advice to the designer so that design problems can be addressed early. It is important to solve. For this reason, a technique for quantitatively grasping the progress of design work from the outside has been desired.

  Therefore, conventionally, a management terminal that manages the progress of design work acquires drawing data and its image data at predetermined time intervals, calculates the degree of progress until completion, and then combines the image data and the degree of progress. The technique of displaying is displayed (for example, refer patent document 1 below).

JP 2006-190199 A

  However, the above-described conventional technology has a problem that it is difficult to determine the progress status with respect to the work time in consideration of the difficulty of design in each phase of the design work. For example, in the initial phase, since the product layout and new mechanism are considered, the CAD operation does not progress much with respect to the work time. Therefore, it is necessary for the administrator to understand the actual situation of such design work and judge the appropriateness of the progress.

  This determination of validity not only requires knowledge of design, but it is also necessary to understand the difficulty of design in each phase and to grasp the details of the design work of each designer. This increases the burden on the administrator for progress management, and sometimes makes it difficult to grasp the progress. For this reason, there is still a problem that rework of the design cannot be prevented and the design period is prolonged.

  In order to eliminate the above-described problems caused by the conventional technology, the present invention manages the progress in consideration of the design difficulty in each phase of the design work, thereby preventing the rework of the design and reducing the design period. It is an object to provide a progress management program, a progress management apparatus, and a progress management method that can be shortened.

  In order to solve the above-described problems and achieve the purpose, the progress management program, the progress management apparatus, and the progress management method are configured to determine a confirmed work man-hour and a confirmed work in a series of work man-hours to be managed. The cumulative work time required for man-hours and the actual work time required for the series of work man-hours are obtained, the ratio of the obtained confirmed work man-hours to the series of work man-hours is calculated, and the entire work is represented by the progress rate. For each phase to be divided, the current phase gradient specified from the calculated ratio is extracted from the table storing the progress rate gradient with respect to the working time of the phase, and the extracted current phase gradient and The target work time for the ratio is calculated based on the actual work time for the series of work man-hours, and the calculated target work time and the acquired cumulative work Comparing the between, and requirements to output the result of comparison.

  According to the progress management program, the progress management device, and the progress management method, the progress of the design work can be determined by changing the gradient of the progress rate with respect to the work time for each phase.

  According to the progress management program, the progress management device, and the progress management method, the progress status is managed in consideration of the difficulty of design in each phase of the design work, thereby preventing the rework of the design and the design period. There is an effect that it can be shortened.

  Exemplary embodiments of a progress management program, a progress management device, and a progress management method will be described below in detail with reference to the accompanying drawings. In this progress management program, progress management device, and progress management method, by changing the slope of the progress rate with respect to the work time for each phase, the progress can be determined according to the difficulty of design in each phase. Appropriate progress management can be performed according to the actual situation of work.

  In this specification, the progress management device is a progress management server, and the progress management program is a program installed in the progress management server. However, the progress management program may be installed in the management terminal or the CAD terminal.

(Overview of progress management)
First, an overview of progress management according to the present embodiment will be described. Here, the progress management of a three-dimensional CAD design work is taken as an example. FIG. 1 is an explanatory diagram showing a fluctuation graph of the progress rate with respect to the working time. The graph 100 represents the correlation between the work time of the design work and the progress rate. The horizontal axis of the graph 100 is the work time [H] of the design work, and the vertical axis is the progress rate [%].

  Here, the progress rate is an index obtained by using the number of CAD features (the number of histories) required for completion of the design target and the number of designed features. A feature is a model that is expressed by a basic shape and parameters (such as dimensions) and is created by executing a predetermined operation on a specific shape.

  Examples of features include fillets, shells, chamfered holes, bosses, and ribs. The final shape to be designed is composed of a plurality of features. In FIG. 1, H1 and H2 represent inflection points at which the slope of the graph 100 changes. Further, in FIG. 1, T represents a target work time for the design work.

  In the graph 100, first, in phase 1 (progress rate: 0 to 20%), the CAD operation does not progress much with respect to the work time in order to consider the layout and the new mechanism. The phase is a work stage in which the entire design work is classified by the progress rate. In phase 1, the shape of an important part that determines the structure of the product is determined.

  In phase 2 (progress rate: 20 to 80 [%]), the CAD operation proceeds at a stroke, and the progress rate increases at a stroke. In phase 2, the CAD operation proceeds at a stroke because a simple operation of creating a bracket to be added incidentally or a notch for escape is performed on the shape determined in phase 1.

  In phase 3 (progress rate: 80 to 100 [%]), since it takes time to check and correct before drawing, the speed of the CAD operation slows down and the number of features increases gradually. Thus, the progress rate of the design work does not simply increase as the work time elapses, but increases according to the design difficulty in each of the phases 1 to 3.

  Therefore, in this progress management, the progress is managed in consideration of the difficulty of design in each phase of the design work by changing the gradient of the progress rate with respect to the work time for each phase. As a result, the progress of the design work can be appropriately determined, the progress management suitable for the actual situation of the design work can be performed, and the efficiency of the design work can be improved.

  Further, the progress rate of each phase that classifies the entire design work changes according to the difficulty level of the design target. Here, the difficulty level is an index determined by the number of CAD features required until the design target is completed. Here, the greater the number of features, the higher the difficulty level. FIG. 2 is an explanatory diagram showing a variation graph of design objects with different difficulty levels.

  In FIG. 2, a graph 210 represents a correlation between the work time of the design work related to the design object having a low difficulty level and the progress rate. In FIG. 2, H3 and H4 represent the inflection points of the graph 210. Further, in FIG. 2, T1 represents a target work time for the design work.

  The graph 220 represents the correlation between the work time of the design work related to the design object having a high difficulty level and the progress rate. In FIG. 2, H5 and H6 represent inflection points of the graph 220. Further, in FIG. 2, T2 represents a target work time for the design work (where T1 <T2).

  As shown in the graphs 210 and 220, the progress rates of the respective phases 1 to 3 for classifying the entire design work change in accordance with the difficulty level of the design target. For example, in the phase 1 in which the CAD operation does not progress much with respect to the work time, 0 to 10 [%] of the design object with a low difficulty level is 0 to 30 [%] in the design object with a high difficulty level. Yes. Therefore, the trajectories of the graphs 210 and 220 are greatly different.

  Therefore, in this progress management, the progress is managed in consideration of the difficulty of the design object by changing the gradient of the progress rate with respect to the work time of the phase for each difficulty representing the difficulty of the design work. Thereby, the progress of the design work can be appropriately determined according to the difficulty level of the design target.

  The increase in the progress rate with respect to the work time of the design work changes according to the skill level of the designer. FIG. 3 is an explanatory diagram showing a variation graph of designers with different skill levels. In FIG. 3, a graph 310 represents the correlation between the work time of a veteran with a high skill level and its progress rate. In FIG. 3, H7 and H8 represent inflection points of the graph 310. Further, in FIG. 3, T3 represents a target work time for the design work.

  The graph 320 represents the correlation between the work time of a new face with a low skill level and the progress rate. In FIG. 3, H9 and H10 represent the inflection points of the graph 320. Further, in FIG. 3, T4 represents a target work time for the design work (where T3 <T4).

  As shown in the graphs 310 and 320, the increase in the progress rate with respect to the work time of the design work changes according to the skill level of the designer. For example, the work time ta that is the first inflection point in the graph 310 is shorter than the work time tb that is the first inflection point in the graph 320. This indicates that the experienced designer is more efficient than the new designer.

  Therefore, in this progress management, the progress is managed in consideration of the skill level of the designer. Thereby, the progress of the design work can be appropriately determined according to the skill level of the designer.

(System configuration of CAD system)
Next, the system configuration of the CAD system according to the present embodiment will be described. FIG. 4 is a system configuration diagram of the CAD system. In FIG. 4, a CAD system 400 includes a progress management server 401, a management terminal 402, and CAD terminals 403-1 to 403-N, such as a network 410 such as the Internet, a LAN (Local Area Network), and a WAN (Wide Area Network).

  In the CAD system 400, the administrator accesses the progress management server 401 using the management terminal 402, so that the progress of design work can be performed without going to the CAD terminals 403-1 to 403-N used by each designer. The situation can be confirmed from the outside.

(Hardware configuration of computer device)
Next, a hardware configuration of the computer apparatus according to the embodiment (the progress management server 401, the management terminal 402, and the CAD terminals 403-1 to 403-N illustrated in FIG. 4) will be described. FIG. 5 is a block diagram of a hardware configuration of the computer apparatus according to the embodiment. In FIG. 5, the computer apparatus includes a CPU (Central Processing Unit) 501, a ROM (Read-Only Memory) 502, a RAM (Random Access Memory) 503, a magnetic disk drive 504, a magnetic disk 505, and an optical disk drive 506.

The magnetic disk drive 504 controls reading / writing of data with respect to the magnetic disk 505 according to the control of the CPU 501. The magnetic disk 505 stores data written under the control of the magnetic disk drive 504.

  The optical disk drive 506 controls the reading / writing of the data with respect to the optical disk 507 according to control of CPU501. The optical disk 507 stores data written under the control of the optical disk drive 506, or causes the computer to read data stored on the optical disk 507.

  The display 508 displays data such as a document, an image, and function information as well as a cursor, an icon, or a tool box. As the display 508, for example, a CRT, a TFT liquid crystal display, a plasma display, or the like can be adopted.

  An interface (hereinafter abbreviated as “I / F”) 509 is connected to a network 410 such as a LAN, a WAN, or the Internet through a communication line, and is connected to another device via the network 410. The I / F 509 manages an internal interface with the network 410 and controls data input / output from an external device. For example, a modem or a LAN adapter may be employed as the I / F 509.

  The keyboard 510 includes keys for inputting characters, numbers, various instructions, and the like, and inputs data. Moreover, a touch panel type input pad or a numeric keypad may be used. The mouse 511 moves the cursor, selects a range, moves the window, changes the size, and the like. A trackball or a joystick may be used as long as they have the same function as a pointing device.

  The scanner 512 optically reads an image and takes in the image data into the computer apparatus. The scanner 512 may have an OCR (Optical Character Reader) function. The printer 513 prints image data and document data. As the printer 513, for example, a laser printer or an ink jet printer can be employed.

(Memory contents such as various databases)
Next, various databases will be described. Functions of various databases and the like are realized by storage devices such as the ROM 502, the RAM 503, the magnetic disk 505, and the optical disk 507 of the progress management server 401 shown in FIG.

  FIG. 6 is an explanatory diagram showing an example of the contents stored in the component DB (database). In FIG. 6, the part DB 600 has fields such as part ID, part name, number of features, difficulty, designer name, skill level, actual work time, and data file name. By setting information in each field, component information 600-1 to 600-n regarding each component is stored as a record.

  Here, the component ID is an identifier for identifying a designed component. The part name is the name of the part. The number of features is the number of CAD features required to complete a part. The difficulty level is an index representing the difficulty in designing a part. Here, the numerical value of difficulty becomes large, so that design becomes difficult. This difficulty level is determined by, for example, the number of CAD features required to complete a part.

  The designer name is the name of the designer of the part. The skill level is an index representing the skill level of the designer. Here, as the skill level of the designer increases, the numerical value of the skill level decreases. The actual work time is the work time taken from the start to the end of the part design work. The data file name is the file name of the part image data.

  FIG. 7 is an explanatory diagram of an example of the contents stored in the progress management DB. In FIG. 7, the progress management DB 700 has fields such as management ID, part name, target feature number, target work time, difficulty level, designer name, skill level, cumulative feature number, cumulative work time, and data file name. By setting information in each field, the progress management information 700-1 to 700-m regarding each part is stored as a record.

  Here, the management ID is an identifier for identifying a management target. The target feature number is the number of CAD features required to complete a part. The target work time is a target work time required to complete a part. The cumulative number of features is the number of features at the current time. The cumulative work time is the work time at the present time.

  FIG. 8 is an explanatory diagram showing an example of the stored contents of the inflection point table. In FIG. 8, the inflection point table 800 has the difficulty level, the inflection point 1, the inflection point 2, and the work time index for each skill level 1 to 3 as fields. Inflection point information 800-1 to 800-15 of the fluctuation graph of the progress rate is stored.

  Here, the inflection point 1 is a progress rate that is the first inflection point in the progress rate fluctuation graph with respect to the work time. The inflection point 2 is a progress rate that is the second inflection point in the progress rate variation graph with respect to the work time. The work time index is an index set according to the skill level of the designer and the difficulty level of the design target. Here, the work time index when a designer with skill level 1 designs a design object with difficulty level 1 is set to “1”. This work time index increases as the skill level or difficulty increases.

  FIG. 9 is an explanatory diagram showing an example of the contents stored in the work efficiency coefficient table. In FIG. 9, the work efficiency coefficient table 900 has the difficulty level, phase 1, phase 2, and phase 3 as fields for the work efficiency coefficients of each skill level 1 to 3, and each phase 1 to 1 for each record. The work efficiency coefficient information 900-1 to 900-15 related to the work efficiency 3 is stored.

  Here, the work efficiency coefficient is a coefficient representing the work efficiency of the design work. The work efficiency coefficient increases as the work efficiency decreases, and decreases as the work efficiency increases. The work efficiency coefficient increases as the difficulty level increases.

  FIG. 10 is an explanatory diagram showing an example of the contents stored in the schedule management DB. In FIG. 10, the schedule management DB 1000 has fields such as management ID, part name, designer name, start date, scheduled end date, update date, accumulated work time, progress rate, and warning flag. By setting information in each field, schedule management information 1000-1 to 1000-m regarding each part is stored as a record.

  Here, the start date is the start date of the design work. The scheduled end date is the scheduled end date of the design work. The update date is an update date when the progress status of the design work is updated. The progress rate is the current progress rate of the design work. The warning flag is a flag indicating a delay in the progress of design work. Although illustration is omitted, warning information is stored in association with a record whose warning flag is “ON”.

(Outline of the CAD system)
Next, an outline of the CAD system 400 will be described. FIG. 11 is an explanatory diagram showing an outline of a CAD system. In the following, CAD terminals 403-1 to 403-N are simply referred to as “CAD terminal 403”.

  In FIG. 11, first, (1) the CAD terminal 403 inputs the part name, the work start date, and the scheduled end date of the part to be designed by the designer's operation input. Various types of input information are transmitted from the CAD terminal 403 to the progress management server 401 via the network 410, and are registered in the schedule management DB 1000 as new records.

  Thereafter, (2) the CAD terminal 403 searches the component DB 600 for a component having a similar shape to the design object. Specifically, for example, the progress management server 401 is accessed, and a record of a part with a similar shape is searched from the part DB 600 using the name of the part to be designed, and the search result is acquired.

  Next, (3) the CAD terminal 403 sets the number of CAD features required to complete the searched similar-shaped part as the target feature number to be designed. Specifically, for example, when a part Bi is searched from the part DB 600, the target feature number to be designed is set to “200”.

  Thereafter, (4) the CAD terminal 403 performs modeling of the design target. Then, (5) the CAD terminal 403 stores drawing data related to the design object and executes an approval process. Here, the approval process is a process in which an administrator or the like receives an approval for completion of the design work using a CAD function.

  In addition, when the drawing data is saved, modeling information related to the design target (see FIG. 13 described later) is transmitted from the CAD terminal 403 to the progress management server 401 via the network 410 and stored in the progress management DB 700. At the time of the first transmission, the progress management server 401 assigns a management ID to the modeling information and registers it as a new record in the progress management DB 700. Further, after the first time, a record is specified with the name as a clue, and the contents of the record are updated.

  (6) If the approval process is unapproved, the progress management server 401 executes a progress management process for managing the progress of the design work related to the design target. If there is a progress delay (“NG” in FIG. 11), (7) warning information indicating the progress delay is created, and (8) the record contents of the schedule management DB 1000 are updated. On the other hand, when there is no progress delay (“OK” in FIG. 11), (8) the record content of the schedule management DB 1000 is updated.

  Further, (9) as a result of the approval process being executed, in the case of approval, the progress management server 401 registers drawing data related to the design object in the component DB 600. Then, (10) the corresponding record is deleted from the progress management DB 700. Finally, (11) the record contents of the schedule management DB 1000 are updated.

(Functional configuration of progress management server)
Next, a functional configuration of the progress management server 401 will be described. FIG. 12 is a block diagram illustrating a functional configuration of the progress management server. In FIG. 12, the progress management server 401 includes an acquisition unit 1201, a first calculation unit 1202, an extraction unit 1203, a second calculation unit 1204, a comparison unit 1205, a determination unit 1206, and a creation unit 1207. The correction unit 1208 and the output unit 1209 are included.

  Specifically, the functions (acquisition unit 1201 to output unit 1209) serving as the control unit are, for example, CPU 501 that stores a program stored in a storage device such as the ROM 502, RAM 503, magnetic disk 505, and optical disk 507 shown in FIG. The function is realized by executing the function or by the I / F 509.

  The acquisition unit 1201 has a function of acquiring a confirmed work man-hour among a series of work man-hours to be managed, a cumulative work time for the confirmed work man-hour, and an actual work time for the series of work man-hours. Have Here, the work is a work performed on a computer, and includes, for example, parts design of industrial products and industrial machines, building design, character design, creation of electronic documents, and the like.

  Moreover, a series of work man-hours is a work man-hour required until all work is completed. The determined work man-hour is a work man-hour that has been completed among all work. The cumulative work time is the work time at the current time taken for the confirmed work man-hours. The actual work time is a target work time taken until the same or similar work as the management target is completed.

  In the following, a work is a CAD drawing design work, a series of work man-hours is a CAD target feature number (history number) required to complete a CAD drawing, and a confirmed work man-hour is This is the cumulative feature number of CAD. Here, the information including the target feature number, the cumulative feature number, the cumulative work time, and the target (actual) work time is referred to as “modeling information”.

  Specifically, for example, the CPU 501 may receive modeling information transmitted from the CAD terminal 403 via the I / F 509. Further, the CPU 501 may accept modeling information by a user operation input using the keyboard 510 and the mouse 511 shown in FIG. 5, or may be obtained by extraction from a database or a library. The acquired modeling information is stored in, for example, the progress management DB 700 shown in FIG.

  Here, a specific example of modeling information will be described. FIG. 13 is an explanatory diagram showing a specific example of modeling information. In FIG. 13, modeling information 1300 has fields such as part name, target feature number, difficulty level, designer name, skill level, cumulative feature number, cumulative work time, target work time, and data file name. Information is set.

  In this case, the CPU 501 receives the modeling information 1300 transmitted from the CAD terminal 403 via the I / F 509 and stores it in the progress management DB 700. At this time, the CPU 501 assigns a management ID to the modeling information 1300 and stores it in the progress management DB 700 (only the first time). From the first time onward, the corresponding record in the progress management DB 700 is specified using the part name and the like as a clue, and the cumulative feature number, cumulative work time, and target work time of the record are updated. Although not shown in the figure, the modeling information 1300 is given an update date as a time stamp for updating the progress status of the design work. Furthermore, although illustration is omitted, the modeling information 1300 may include the skill level of the worker when the target work time is measured and the difficulty level of the part to be measured.

  The first calculation unit 1202 has a function of calculating the current progress rate of the design work based on the acquired modeling information. Specifically, for example, the CPU 501 calculates the current progress rate by obtaining the ratio of the cumulative feature number to the target feature number. The calculated result is stored in a storage device such as the ROM 502, RAM 503, magnetic disk 505, and optical disk 507 shown in FIG.

  Here, the calculation processing by the first calculation unit 1202 will be described using the modeling information 1300 as an example. In this case, the CPU 501 refers to the target feature number and the cumulative feature number of the modeling information 1300, and calculates the ratio (= 20/200) of the cumulative feature number to the target feature number. Here, the current progress rate is 10 [%].

  For each phase that classifies the entire design work by the progress rate, the extraction unit 1203 stores the current phase identified from the calculated current progress rate from the table that stores the gradient of the progress rate with respect to the work time of the phase. It has a function of extracting the gradient. Here, the table is, for example, the work efficiency coefficient table 900 shown in FIG.

  Further, the gradient of the progress rate with respect to the work time is an index representing an increase in the progress rate per unit work time. This gradient may be, for example, a gradient for each phase in a variation graph representing the progress rate with respect to the working time, or may be a work efficiency coefficient representing a relative work efficiency between phases.

  Here, the extraction process by the extraction unit 1203 will be described using the above-described “current progress rate: 10 [%]” as an example. In this case, first, the CPU 501 specifies the inflection point information 800-2 from the inflection point table 800 shown in FIG. 8 with reference to the difficulty level and skill level of the modeling information 1300.

  Then, the CPU 501 specifies the current phase from the current progress rate. Here, since the first inflection point is 10 [%], the current phase is phase 1 (0 to 10 [%]). Next, the CPU 501 refers to the difficulty level and skill level of the modeling information 1300, and specifies the work efficiency coefficient information 900-2 from the work efficiency coefficient table 900.

  Then, the CPU 501 specifies a work efficiency coefficient from the current phase, and extracts the work efficiency coefficient from the work efficiency coefficient table 900. Here, since the current phase is phase 1, the work efficiency coefficient is 1.22. Note that the extracted extraction results are stored in a storage device such as the ROM 502, the RAM 503, the magnetic disk 505, and the optical disk 507, for example.

  The second calculation unit 1204 has a function of calculating the target work time with respect to the current progress rate based on the extracted current phase gradient and the target work time for the design work. Hereinafter, an example of specific processing contents for calculating the target work time with respect to the current progress rate will be described. The calculated result is stored in a storage device such as the ROM 502, RAM 503, magnetic disk 505, and optical disk 507, for example.

  Specifically, for example, first, the CPU 501 extracts the gradient for each phase before the current phase. Then, the CPU 501 calculates the target work time with respect to the current progress rate based on the extracted gradient for each phase before the current phase and the target work time for the design work.

More specifically, for example, the CPU 501 can calculate the target work time with respect to the current progress rate using the following formulas (1) and (2). However, RTa is the target work time for the current progress rate, RT (k-1) is the target work time for the design work in phase (k-1), and Ta is the target work time for the design work. , RP is the current progress rate, CP _k-1 is the progress rate of the inflection point where the previous phase is switched to the current phase, EC _k is the work efficiency factor of the current phase, and EC _k-1 Is the work efficiency factor of phase (k-1). Also, RT (0) = 0.

RT (k−1) = Ta × CP _k−1 × EC _k−1 (2)

  In the example described above, since the current phase is phase 1, when k = 1 and the values of the respective parameters are substituted into the above equation (1), the target work time RTa with respect to the current progress rate is “RTa = 0 + {120 × (0.1-0) × 1.22} = 14.64 [H] ”.

  The comparison unit 1205 has a function of comparing the target work time with respect to the current progress rate calculated by the second calculation unit 1204 and the accumulated work time acquired by the acquisition unit 1201. In the example described above, the target work time “14.64 [H]” with respect to the current progress rate is compared with the accumulated work time “14 [H]”. The compared result of comparison is stored in a storage device such as the ROM 502, RAM 503, magnetic disk 505, and optical disk 507, for example.

  The output unit 1209 has a function of outputting the compared result of comparison. Specifically, for example, the CPU 501 outputs the target work time with respect to the current progress rate and the accumulated work time in association with each other to the I / F 509. Examples of the output format include display on the display 508, print output to the printer 513, and transmission to an external device via the I / F 509. Alternatively, the data may be stored in a storage device such as the RAM 503, the magnetic disk 505, and the optical disk 507.

  The determination unit 1206 has a function of determining whether the accumulated work time is equal to or less than the target work time with respect to the current progress rate as a result of the comparison by the comparison unit 1205. Specifically, for example, the CPU 501 determines whether or not a value obtained by subtracting the target work time with respect to the current progress rate from the accumulated work time is 0 or more. If the subtracted value is not 0 or more, the CPU 501 determines that the accumulated work time is equal to or less than the target work time with respect to the current progress rate.

  The creation unit 1207 has a function of creating warning information regarding a delay in the progress of the design work when it is determined that the accumulated work time is not less than or equal to the target work time with respect to the current progress rate. Specifically, for example, the CPU 501 creates a warning message with a work time delayed by a value obtained by subtracting the target work time for the current progress rate from the accumulated work time.

  The output unit 1209 has a function of outputting the generated warning information. Specifically, for example, the CPU 501 stores the created warning information in the schedule management DB 1000. More specifically, for example, using the management ID as a clue, the record is identified from the schedule management DB 1000, the warning flag is changed to “ON”, and the record and the warning information are stored in association with each other.

  Based on the skill level of the designer and the skill level of the designer (hereinafter referred to as “pre-designer”) when the actual work time required for the design work is measured, the correction unit 1208 sets the target for the current progress rate. It has a function of correcting work time. The corrected result is stored in a storage device such as the ROM 502, RAM 503, magnetic disk 505, and optical disk 507, for example.

  Specifically, for example, the CPU 501 performs work in accordance with the skill level of the previous worker based on the difficulty level of the part that is the measurement target of the actual work time included in the modeling information and the skill level of the previous designer. The time index is extracted from the inflection point table 800. Then, the CPU 501 corrects the target work time with respect to the current progress rate by using the ratio of the work time index corresponding to the skill level of the previous worker to the work time index corresponding to the skill level of the designer.

  More specifically, for example, the CPU 501 corrects the target work time with respect to the current progress rate by multiplying the target work time with respect to the current progress rate by the above ratio. In this case, the CPU 501 compares the corrected target work time with the accumulated work time.

(Schedule management screen)
Here, the schedule management screen displayed on the display 508 of the management terminal 402 will be described. This schedule management screen is displayed on the display 508 by accessing the schedule management DB 1000 of the progress management server 401 from the management terminal 402.

  FIG. 14 is an explanatory diagram illustrating an example of a schedule management screen. In FIG. 14, the schedule management screen 1400 displays an index 1410 to be managed. In the management terminal 402, the schedule management table 1420 can be displayed by moving the cursor C and designating an arbitrary management target by a user operation input.

  In the schedule management screen 1400, a bar graph 1430 represents the start date and the scheduled end date of the design work. Here, March 17 is the scheduled end date of the design work. The bar graph 1440 represents the update date of the design work. Here, March 6 is the update date.

  Also, the warning information 1450 represents a message indicating a progress delay. Here, in Phase 1, a progress delay of 4 [H] occurs. Furthermore, the image data 1460 is image data relating to a part that has been designed at the present time. By checking this schedule management screen 1400, the administrator can grasp the progress of the design work of each designer.

(Progress management processing procedure by progress management server)
Next, a progress management processing procedure by the progress management server 401 according to the present embodiment will be described. FIG. 15 is a flowchart illustrating an example of a progress management processing procedure by the progress management server. In the flowchart of FIG. 15, first, the acquisition unit 1201 determines whether modeling information from the CAD terminal 403 has been acquired (step S1501).

  Here, after waiting for the modeling information to be acquired (step S1501: No) and when acquired (step S1501: Yes), the first calculation unit 1202 uses the acquired modeling information to determine the target of the cumulative feature number. A ratio to the number of features is obtained, and a current progress rate is calculated (step S1502).

  Next, the CPU 501 refers to the difficulty level and skill level of the modeling information, identifies the corresponding record from the inflection point table 800, and identifies the current phase from the calculated progress rate (step). S1503). Then, the extraction unit 1203 extracts the work efficiency coefficient for each phase before the current phase from the work efficiency coefficient table 900 (step S1504).

  Thereafter, the second calculation unit 1204 calculates the target work time for the current progress rate using the above formulas (1) and (2) (step S1505). Then, the extraction unit 1203 refers to the modeling information and extracts a work time index corresponding to the skill level of the designer and the previous designer from the inflection point table 800 (step S1506).

  Next, the correction unit 1208 corrects the target work time with respect to the current progress rate by multiplying the ratio of the work time index of the previous worker to the work time index of the designer by the calculated target work time ( Step S1507). Then, the comparison unit 1205 compares the target work time with respect to the calculated current progress rate and the accumulated work time included in the modeling information (step S1508).

  Next, the determination unit 1206 determines whether or not the accumulated work time is equal to or less than the target work time with respect to the current progress rate (step S1509). If the accumulated work time is not less than or equal to the target work time with respect to the current progress rate (step S1509: No), the creation unit 1207 creates warning information regarding the progress delay of the design work (step S1510).

  Then, the CPU 501 updates the record contents of the schedule management DB 1000 based on the created warning information and modeling information (step S1511), and ends the series of processes according to this flowchart.

  In step S1509, when the accumulated work time is equal to or less than the target work time with respect to the current progress rate (step S1509: Yes), the CPU 501 updates the record contents of the schedule management DB 1000 based on the modeling information (step S1511). ), A series of processes according to this flowchart is terminated.

  As described above, according to the present embodiment, the progress is managed in consideration of the difficulty of design in each phase of the design work by changing the gradient of the progress rate with respect to the work time for each phase. Can do. In addition, by changing the gradient of the progress rate with respect to the phase work time for each difficulty level representing the difficulty of the design work, the progress status can be managed in consideration of the difficulty level of the design target.

  Furthermore, the target work time with respect to the current progress rate can be corrected in consideration of the skill level of the designer. Thereby, the progress of the design work can be appropriately determined according to the skill level of the designer.

  Therefore, according to this progress management program, progress management device, and progress management method, it is possible to manage the progress according to the actual situation of the design work, thereby preventing the rework of the design and shortening the design period. Can be realized

  The progress management method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation.
