[0002] With the deep integration of production between shipbuilding factories, the construction of related products across production areas is becoming more frequent, and the fine management of shipbuilding must introduce actual cost analysis. Based on the fine dispatching objects of each level task (WP / WO / WJ), the actual man-hours and the design quantity of the design quota man-hours in the production process are compared and analyzed. However, the existing engineering quantity measurement standards and rules of each process in each factory area are not unified, the process evaluation granularity is inconsistent, and the understanding and application level of the production department for the quota man-hours are uneven. The input and output analysis of new equipment, new technology and new process lacks basic support. Moreover, due to the different granularity of the design quantity of each process of a single ship, the design quantity of a single ship has tens of thousands of records, and each process has its own parameter standard for calculating the design quantity of the quota man-hours. The design quantity of the quota man-hours of each process is calculated by manual method, and the correctness of the calculation result cannot be guaranteed. The efficiency is extremely low, and the design quantity of the quota man-hours of each process of a single ship cannot be applied to the cost analysis of shipbuilding.

[0040] In order to make the technical solution of the present application better understood by the person skilled in the art, the present application will be described in detail below in combination with the drawings and specific embodiments.

[0041] The various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0042] These and other characteristics of the present application will become apparent from the following description of the preferred forms thereof given with reference to the accompanying drawings.

[0043] It should also be understood that, while the present application has been described above with reference to specific embodiments, the person skilled in the art can certainly implement many other equivalent forms of the present application, which have the features as claimed and thus all fall within the protection scope defined thereby.

[0044] The above and other aspects, features and advantages of the present application will become more apparent in light of the following detailed description when taken in conjunction with the accompanying drawings in which:

[0045] Specific embodiments of the present application are described hereinbelow with reference to the accompanying drawings; however, it is to be understood that the described embodiments are merely examples of the present application, which can be embodied in various ways. Well-known and / or redundant functions and structures are not described in detail to avoid obscuring the present application by unnecessary or redundant detail in accordance with the user's history of operation, determining the true intention, avoiding unnecessary or redundant details to make the present application obscure. Therefore, the specific structural and functional details described herein are not intended to be limiting, but are merely used as a basis for the claims and a representative basis for teaching those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0046] The present specification can use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which can refer to one or more of the same or different embodiments of the application.

[0047] The principles and features of the present application are described below in conjunction with the accompanying drawings, in which the embodiments are shown for the purpose of explanation only and are not intended to limit the scope of the present application. The following description is made in conjunction with the accompanying drawings. Figure 1 The preferred embodiments of the present application are further described in detail:

[0048] The shipbuilding processes include hull manufacturing preprocessing (plates and profiles), hull manufacturing cutting (plates and profiles), hull manufacturing splicing (profiles), hull manufacturing processing (profile cold bending, cold processing, cold processing, scattered part polishing, and tooling / other), hull manufacturing welding / assembly / polishing (small groups, medium groups, and large groups), general assembly, and loading, etc. The process involved in the embodiments of the present application is the plate blanking process in the shipbuilding processes.

[0049] As shown in the drawings, the embodiments of the present application provide a plate blanking quota man-hour calculation method for shipbuilding, which comprises the following steps: Figure 1 Step S1, establishing a quota man-hour standard for plate blanking according to resource allocation of different construction plants;

[0050] The quota standard for plate blanking includes construction plant, name, cutting type, material quantity unit, reference man-hour (hour), plate thickness range interval, and corresponding coefficient. Since the resources matched in different construction plants for plate blanking operation in shipbuilding are not the same, the man-hour consumed by plate blanking is also not the same, so the reference man-hour of the quota man-hour should be distinguished from different construction plants and cutting operation types.

[0051] In addition, the man-hour consumed by plate blanking is affected by the thickness of the steel plate, as shown in the drawings.

[0052] Figure 3 ​As shown, the quota standard of plate cutting can set the thickness range interval and the corresponding coefficient, the thickness range interval is represented by open interval symbol "(greater than" and ") less than", closed interval symbol "[greater than or equal to" and "] less than or equal to", followed by the corresponding coefficient, multiple thickness range intervals are separated by semicolons, such as "(0,8)1.00; [8,20)1.08; [20,100]1.54", which represents the plate thickness range interval and coefficient: if the thickness of the steel plate used for a certain part is greater than 0 and less than 8 (mm), the coefficient is 1.00; if the thickness of the steel plate used for a certain part is greater than or equal to 8 and less than 20, the coefficient is 1.08; if the thickness of the steel plate used for a certain part is greater than or equal to 20 and less than or equal to 100, the coefficient is 1.54, if the thickness range interval and the corresponding coefficient are not set, or the thickness of the steel plate used for a certain part is not in the set thickness range interval, the corresponding coefficient is 1.

[0053] Step S2, obtaining the designed quantity of plate cutting for building a ship;

[0054] The designed quantity of plate cutting includes ship number, section number, nesting card number, specification, material, total cutting length, marking length, idle travel length, and processing / flow direction code, the processing / flow direction code is used to represent the process flow stage and process mode of plate processing, the designed quantity of plate cutting for each section of a single ship can be extracted from the design system SPDM (shipbuilding product data management system), or imported through Excel of fixed format plate cutting.

[0055] Step S3, calculating the rated working hours.

[0056] After determining the plate cutting quota standard data and the designed quantity of plate cutting for each section of a single ship, the rated working hours of each part of the ship section when completing the plate cutting process can be calculated;

[0057] First, define a multi-dimensional array for storing the designed quantity of plate cutting and the corresponding quota working hours standard, the specific operation is as follows,

[0058] Define a multi-dimensional array:

[0059] Type

[0060] Arr=Record of

[0061] Hd1:Float;

[0062] Exp1:String;

[0063] Hd2:Float;

[0064] Exp2:String;

[0065] Hdxs:Float;

[0066] End;

[0067] TArr: Array of Arr;

[0068] The second step is to obtain the shipyard area for the ship number whose quota work hours need to be calculated.

[0069] The third step is to load the design quantity data of the plate cutting for each section of the ship into a multidimensional array, and determine the reference man-hour, plate thickness range and corresponding coefficients for each part by using the thickness of the steel plate where each part is located, the processing / flow code and the ship's construction site. The specific operation is as follows:

[0070] (1) Clear the TArr array;

[0071] (2) Based on the processing / flow code of the part (to determine the cutting type of the plate material) and the ship's construction site, obtain the baseline working hours from the plate material cutting quota standard and assign them to the variable Jzgs.

[0072] (3) Assign the thickness range and coefficient expression to the variable Expr;

[0073] (4) If the length of variable Expr is 0, that is, the thickness range and coefficient are not defined, then Hdxs = 1, and jump to step (11) in the third step;

[0074] (5) If the length of Expr is greater than 0, check if there is a semicolon ";". If not, assign Expr to variable S1 and set Expr to null. If there is a semicolon ";", assign the thickness range and coefficient before the semicolon ";" to variable S1, and delete the first semicolon ";" and all characters before it in Expr.

[0075] (6) Determine whether each character in S1 is a number from "0" to "9", or "(", "[", ")", "]", ".", ",". If not, the definition of the thickness range and coefficient of the segment is incorrect, and jump to step (5) in step 3.

[0076] (7) Determine whether the first character of S1 is “(” or “[”. If not, the definition of the thickness range and coefficient of the segment is incorrect. Jump to step (11) in step 3. If yes, add an item to array TArr. At the same time, store ">” or ">=" in array TArr's Exp1 and delete the first character of S1.

[0077] (8) Store the character before “,” into array TArr’s Hd1, and delete “,” and all characters before it from S1.

[0078] (9) Store the character before “)” or “]” into Hd2 of array TArr, and store “<” or “<=” into Exp2 of array TArr. Delete “)” or “]” and all characters before it from S1.

[0079] (10) Store the remaining characters of S1 into the array TArr's Hdxs, thus completing a parsing operation of the thickness range and coefficients.

[0080] (11) If the length of Expr is still greater than 0, jump to step (5) in the third step and continue to analyze the thickness range and coefficients of the next segment.

[0081] (12) End the analysis operation of thickness range interval and coefficient;

[0082] The fourth step is to obtain the coefficient for the thickness range based on the thickness of the steel plate containing the part, and then calculate the standard working time for each part in the plate cutting process = cutting length (Cd) × standard working time (Jzgs) × thickness coefficient (Hdxs):

[0083] (1) Obtain the thickness (Hd) and cutting length (Cd) of the steel plate containing the part;

[0084] (2) Loop through the array TArr(For i:=Low(TArr)To High(TArr)Do);

[0085] (3) If the current Exp1 of array TArr is ">", Exp2 is "<", and the variable Hd is greater than Hd1 and less than Hd2 of array, satisfying the thickness range, obtain the thickness range coefficient and assign it to variable Hdxs, break out of the loop to traverse the array, and go to step (8) in step 4 to calculate the current part's blanking quota time.

[0086] (4) If the current Exp1 of array TArr is ">", Exp2 is "<=", and variable Hd is greater than Hd1 and less than or equal to Hd2 of array, satisfying the thickness range, obtain the thickness range coefficient and assign it to variable Hdxs, exit the loop to traverse the array, and go to step (8) in step four to calculate the current part's blanking quota time:

[0087] (5) If the current Exp1 of array TArr is ">=", Exp2 is "<", and the variable Hd is greater than or equal to Hd1 of array and less than Hd2 of array, satisfying the thickness range, obtain the thickness range coefficient and assign it to variable Hdxs, break out of the loop to traverse the array, and go to step (8) in step four to calculate the current part's blanking quota time:

[0088] (6) If the current Exp1 of array TArr is ">=", Exp2 is "<=", and variable Hd is greater than or equal to Hd1 and less than or equal to Hd2 of array, satisfying the thickness range, obtain the thickness range coefficient and assign it to variable Hdxs, exit the loop to traverse the array, and go to step (8) in step four to calculate the current part's blanking quota time:

[0089] (7) If after iterating through the array TArr, no satisfactory thickness range is found after the comparisons in steps (3), (4), (5), and (6) of step 4, then assign variable Hdxs = 1;

[0090] (8) Calculate the current part's material cutting quota time = Cd * Jzgs * Hdxs.

[0091] Step 5: For the design quantity of plate material for each section of the ship under load, repeat steps (1) to (12) of step 3 and steps (1) to (8) of step S3 to calculate the material quota time for each part of each section of the ship until the loop is completed.

[0092] The above algorithm for calculating the standard working hours for sheet metal cutting yields the standard working hours for the cutting of all parts used in shipbuilding. This provides a benchmark and support for work assignment, resource allocation, on-site management, labor cost settlement, and actual cost analysis.

[0093] like Figure 2 As shown, the master data in the design quantity for production issued by the design department contains the data of all steel plates of the selected ship (H2441) and section (913), while the detailed data contains the parts to be cut from each plate. For example, on the current interface, it shows the parts to be cut from the steel plate with the material card number "13A913308" (blue display row) (47 parts).

[0094] like Figure 4 The figure shows the plate cutting data for section 941 of the H2441 ship in a certain embodiment. The following conditions must be met: (1) the steel plate thickness is less than 30mm; (2) among all the parts to be cut, if any part's processing / flow code contains the letter "F" or "P", then that steel plate must enter the "CNC cutting plasma large plate" processing and cutting process. In the figure, there are 30 steel plates for section 941, but only 17 plates actually need to enter the "CNC cutting plasma large plate" process. Figure 5 And calculate the working hours.

[0095] Figure 5In the standard sheet metal cutting quota, the baseline working time is obtained from "CNC Cutting (Plasma) - Large Plates", Jzgs = 0.032. The first line (material card number 41A941007) has a steel plate thickness of 8mm. The thickness coefficient is obtained from the custom range and coefficient, Hdxs = 1.08. The sheet metal cutting quota working time for this steel plate is calculated as follows: Total Cutting Length (Cd) x Baseline Working Time (Jzgs) x Thickness Coefficient (Hdxs) = 110.979 * 0.032 * 1.08 = 3.84 (rounded to two decimal places). The calculation method for the sheet metal cutting quota working time of other steel plates is the same.

[0096] like Figure 6 The figure shows the plate cutting data for section S41 of ship H2441 in a certain embodiment of the design. The conditions to be met are: (1) the thickness of the steel plate is less than 30mm; (2) among all the parts to be cut, none of the parts have the processing / flow code containing the letters "F" or "P". Then the steel plate will enter the "CNC cutting of plasma internal components" processing and cutting process. In the figure, there are 47 steel plates for section S41. In fact, only 41 steel plates will enter the "CNC cutting of plasma internal components" process, as shown in Figure 7, and the working time will be calculated.

[0097] The baseline working time, Jzgs = 0.026, is obtained from the "CNC Cutting (Plasma) - Internal Components" section of the sheet metal cutting quota standard. The first line (material card number 41S104001) has a steel plate thickness of 10mm. The thickness coefficient, Hdxs = 1.08, is obtained from the user-defined range and coefficient. The sheet metal cutting quota working time for this steel plate is calculated as follows: Total Cutting Length (Cd) x Baseline Working Time (Jzgs) x Thickness Coefficient (Hdxs) = 7.55 * 0.026 * 1.08 = 0.21 (rounded to two decimal places). The calculation method for the sheet metal cutting quota working time for other steel plates is the same.

[0098] like Figure 8 The figure shows the plate cutting data for section S46 of ship H2441 in a certain embodiment of the design. The conditions to be met are: (1) the thickness of the steel plate is greater than or equal to 30mm; (2) among all the parts to be cut, none of the parts has the processing / flow code containing the letter "T", then the steel plate should enter the "gantry flame cutting---non-T row" processing and cutting process. In the figure, there are 78 steel plates for section S46, but only 2 steel plates actually need to enter the "gantry flame cutting---non-T row" process. Figure 9 And calculate the working hours.

[0099] The baseline working time for "Gantry Flame Cutting - Non-T-Panel" in the sheet metal cutting quota standard is obtained as Jzgs = 0.107. For the first line (material card number 46M107236), the steel plate thickness is 30mm. The thickness coefficient, Hdxs = 1.54, is obtained from the custom range and coefficient. The sheet metal cutting quota working time for this steel plate is calculated as follows: Total Cutting Length (Cd) x Baseline Working Time (Jzgs) x Thickness Coefficient (Hdxs) = 54.689 * 0.107 * 1.54 = 9.01 (rounded to two decimal places). The calculation method for the sheet metal cutting quota working time for other steel plates is the same.

[0100] like Figure 10 The figure shows the plate cutting data for section S15 of ship H2469 in a certain embodiment of the design. The conditions to be met are: (1) the thickness of the steel plate is greater than or equal to 30mm; (2) among all the parts to be cut, one part has the processing / flow code containing the letter "T", then the steel plate should enter the "gantry flame cutting---T-row" processing and cutting process. In the figure, there are 55 steel plates for section S15, but only 1 steel plate actually enters the "gantry flame cutting---T-row" process. Figure 11 As shown, the working hours are calculated.

[0101] The baseline working time for "Gantry Flame Cutting - T-Panel" in the sheet metal cutting quota standard is obtained as Jzgs = 0.02. For the first row (material card number 15M123043), the steel plate thickness is 35. The thickness coefficient, Hdxs = 1.54, is obtained from the custom range and coefficient. The sheet metal cutting quota working time for this steel plate is calculated as follows: Total Cutting Length (Cd) x Baseline Working Time (Jzgs) x Thickness Coefficient (Hdxs) = 2.486 * 0.02 * 1.54 = 0.08 (rounded to two decimal places). The calculation method for the sheet metal cutting quota working time for other steel plates is the same.

[0102] like Figure 12 The figure shows the plate cutting data for section S49 of ship H2441 in a certain embodiment of the design. The conditions to be met are: (1) the steel plate thickness is less than 30mm; (2) the processing / flow code of the part to be cut contains the letter "F" or "P", then the part should enter the "large plate beveling" processing and cutting process. In the figure, there are 72 steel plates in section S49, of which only 21 steel plates have processing / flow codes of the parts to be cut containing the letter "F" or "P", such as Figure 13 Calculate the working hours for parts (not steel plates) containing the letters "F" or "P".

[0103] The baseline working time, Jzgs = 0.054, is obtained from the "Beveling Cutting of Large Plates" in the standard sheet metal cutting quota. For the first steel plate (material card number 49M225201), the thickness is 8 mm. The thickness coefficient, Hdxs = 1.08, is obtained from the custom range and coefficient. The sheet metal cutting quota working time for the first part of this steel plate (part code 225-BS0A-GR10B-A1) is calculated as follows: Cutting length (Cd) x Baseline working time (Jzgs) x Thickness coefficient (Hdxs) = 32.715 * 0.054 * 1.08 = 1.91 (rounded to two decimal places). The calculation method for the sheet metal cutting quota working time for the remaining parts is the same.

[0104] like Figure 14 The figure shows the plate cutting data for section S55 of ship H2441 in a certain embodiment of the design. The conditions to be met are: (1) the steel plate thickness is less than 30mm; (2) the processing / flow code of the part to be cut does not contain the letters "F" or "P", then the part should enter the "internal structure beveling" processing and cutting process. In the figure, there are 74 steel plates for section S55, of which only 55 steel plates have processing codes / flow codes of the parts to be cut that do not contain the letters "F" or "P". Figure 15 For parts that do not contain the letters "F" or "P" (not steel plates), calculate the working hours.

[0105] like Figure 16 The figure shows the plate cutting data for the S60 section of the H2441 ship issued by the design. The following conditions must be met: (1) If the processing code / flow code of the part to be cut does not contain the letter "T", then the part must enter the "transition bevel cutting" processing and cutting process. In the figure, there are 55 steel plates in the S60 section, of which only 54 steel plates have processing codes / flow codes of the parts to be cut that do not contain the letter "T", such as Figure 17 For parts that do not contain the letter "T" (not steel plates), calculate the working hours.

[0106] The baseline working time, Jzgs = 0.11, is obtained from the "transition bevel cutting" standard for sheet metal cutting. For the first steel plate (material card number 60M604001), with a thickness of 10, the thickness coefficient, Hdxs = 1.08, is obtained from the custom range and coefficient. The sheet metal cutting quota working time for the first part (part code 604-GR4U-BK107Q-A1) of this steel plate is calculated as follows: Cutting length (Cd) x Baseline working time (Jzgs) x Thickness coefficient (Hdxs) = 1.921 * 0.11 * 1.08 = 0.23 (rounded to two decimal places). The calculation method for the sheet metal cutting quota working time for the remaining parts is the same.

[0107] In addition, embodiments of the present invention also provide a computer-readable storage medium having a computer program stored thereon, wherein the program, when executed by a processor, implements the method for calculating the quota of labor time for cutting steel plates for shipbuilding according to any embodiment of the present invention.

[0108] In addition, this invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the method for calculating the quota of shipbuilding plate cutting time according to any embodiment of this invention.

[0109] The modules implementing the embodiments of the present invention are configured in a device with an I / O communication port, access to Web services, and a display screen. These devices are generally devices with networking and computing capabilities, including but not limited to desktop computers, laptops, and tablets.

[0110] Furthermore, the module implementing the embodiments of the present invention can be configured in the operating system of the device, that is, the module is a system-level application, and the operating system includes, but is not limited to, Android and Windows.

[0111] That is, all the steps in the above method process are executed by the above-mentioned device (or the above-mentioned application).

[0112] This invention first analyzes the working nature of the plate cutting process and establishes a standard time for plate cutting based on the resource allocation of different construction sites. This standard includes the construction site, cutting type, benchmark time, thickness range, and corresponding coefficients. Secondly, different methods are used to obtain the design quantity of plate cutting for shipbuilding. By comparing the processing / flow code of each part and the thickness of the steel plate on which the part is located with the standard time, the corresponding benchmark time and thickness range coefficient are obtained. Finally, the standard time spent on plate cutting for each part is calculated (standard time = cutting length × benchmark time × thickness range coefficient).

[0113] If the quota time for cutting steel plates for shipbuilding (more than 70,000 parts) is calculated manually, firstly, it is time-consuming to collect and organize the design quantity of the steel plates; secondly, it is easy to make mistakes in obtaining the benchmark time and thickness range coefficient for each part, thus affecting the calculation result of the quota time for cutting (quota time = cutting length × benchmark time × thickness range coefficient).

[0114] The above-described method for calculating the standard working hours for sheet metal cutting yields the standard working hours for the cutting of all parts used in shipbuilding. This method is highly efficient and provides a benchmark and support for work assignment, resource allocation, on-site management, labor cost settlement, and actual cost analysis.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
