Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a method, storage medium, and equipment for calculating the quota time for shipbuilding profile processing. Background Technology

[0002] With the deepening integration of production between shipbuilding plants and the increasingly frequent cross-regional construction of related products, refined management of shipbuilding must incorporate actual cost analysis. This involves comparing the actual working hours during the production process—including work-in-process (WP / WO / WJ) at each level, and the standard working hours for the designed quantities—with the work-in-process quotas based on the specific tasks (WP / WO / WJ) across different plants to analyze efficiency. However, issues such as inconsistent standards and rules for measuring the workload of each process across different plants, and inconsistent granularity of process evaluation, along with varying levels of understanding and application of standard working hours among production departments, hinder the accurate calculation of the standard working hours for each process. Furthermore, the granularity of the designed quantities for each process on a single ship varies, and with hundreds of thousands of design quantities recorded for a single ship, and each process having its own standard parameters for calculating standard working hours, manually calculating the standard working hours for each process is inefficient and cannot guarantee accuracy. This makes it impossible to apply the standard working hours for each process on a single ship to the cost analysis of shipbuilding.

[0003] In response to the strategy of high-quality development, to gradually unify rules, to clarify the evaluation criteria for efficiency improvement between processes in factories, and to further strengthen and consolidate the measures for cost reduction and efficiency improvement, it is urgent to formulate a unified standard for time quotas so that it can serve as a basic guide for production, cost management and other units to clarify their goals and take unified actions. Summary of the Invention

[0004] In view of the above-mentioned problems existing in the prior art, the present invention provides a method, storage medium and equipment for calculating the quota time of shipbuilding profile processing, so as to solve the technical problem of lack of unified time quota standards in the prior art.

[0005] This invention provides a method for calculating the standard working hours for shipbuilding profile processing, comprising the following steps:

[0006] Step S1: Establish the standard time quota for profile processing based on the resource allocation of different construction plant areas;

[0007] Step S2: Obtain the design quantity of profiles for shipbuilding.

[0008] Step S3: Calculate the rated working hours.

[0009] In one embodiment, the quota standard for profile processing includes the construction area, process name, unit of measurement, benchmark working hours, range of profile width, and corresponding coefficients.

[0010] In one embodiment, the design quantities for the profile processing include ship number, section number, nested profile number, specifications, material, profile length, total cutting length, scribing length, and idle length.

[0011] In one embodiment, the design quantity of the profile processing also includes a processing / flow code, which is used to characterize the process flow stage and process method of profile processing.

[0012] In one embodiment, the design quantities of profiles for each section of a single ship are extracted from the design system SPDM or imported via an Excel file with a fixed format for profile processing.

[0013] In one embodiment, step S3 specifically includes,

[0014] Step S31: Define a multidimensional array to store the design quantity of profile processing and the corresponding standard time quota;

[0015] Step S32: Obtain the shipyard area for the ship number whose quota work hours are to be calculated.

[0016] Step S33: Load the material quantity data of profile processing design for each section of the ship into a multidimensional array, and determine the base man-hour and profile width range coefficient corresponding to each profile by means of the processing / flow code of each profile, the width of the profile and the shipbuilding yard.

[0017] Step S34: Calculate the standard working hours for each profile in the profile processing procedure. The standard working hours = cold bending reference working hours × cold bending width range coefficient, or the standard working hours = angle bending reference working hours × angle bending width range coefficient.

[0018] 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, is the method for calculating the quota time for shipbuilding profile processing as described in any embodiment of the present invention.

[0019] 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 time of shipbuilding profile processing according to any embodiment of this invention.

[0020] Compared with the prior art, the beneficial effects of the method, storage medium and equipment for calculating the quota time of shipbuilding profile processing provided by the embodiments of the present invention are as follows:

[0021] 1. This invention analyzes the working nature of profile processing procedures, establishes standard time quotas for profile processing based on resource allocation in different construction sites, and further calculates the standard time quotas for processing each profile by combining the design quantity of profile processing. This significantly improves calculation efficiency and accuracy, and provides effective support for management in areas such as work assignment, resource allocation, on-site management, labor cost settlement, and actual cost analysis.

[0022] 2. This invention utilizes the high-speed and precise computing power of computers to calculate the theoretical standard hours for the design quantities of each process at different granularities during production, based on the standard hours for each process. This fully leverages the standard hours as a benchmark and standard in production management, thereby motivating employees and improving work efficiency. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Various embodiments and features of this application are described herein with reference to the accompanying drawings.

[0030] These and other features of this application will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0031] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0032] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0033] Specific embodiments of this application are described below with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0034] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0035] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention. The following description, in conjunction with... Figure 1-5 The preferred embodiments of the present invention will be described in further detail below:

[0036] like Figure 1 As shown, this embodiment of the invention provides a method for calculating the standard working hours for shipbuilding profile processing, including the following steps:

[0037] Step S1: Establish the standard time quota for profile processing based on the resource allocation of different construction plant areas;

[0038] The quota standard for profile processing includes the construction site, name, unit of measurement, base man-hour (hours), range of profile width, and corresponding coefficients. Since the resources available for profile processing operations in different construction sites vary, the man-hours consumed in profile processing also vary. Therefore, the base man-hour for quota man-hours should be different for different construction sites.

[0039] The processing time for other profiles is affected by the width of the profile, such as... Figure 3As shown, the quota standard for profile processing can set a width range and corresponding coefficients. The width range is represented by the open interval symbols "(greater than" and ") less than", and the closed interval symbols "[greater than or equal to" and "] less than or equal to", followed by the corresponding coefficient. Multiple width ranges are separated by semicolons, in the form of "(0,140)1.00; [140,280]1.08; (280,1000]1.54", which means that if the width (mm) of a certain profile is greater than 0 and less than 140, the coefficient is 1.00; if the width of a certain profile is greater than or equal to 140 and less than or equal to 280, the coefficient is 1.08; if the width of a certain profile is greater than 280 and less than or equal to 1000, the coefficient is 1.54. If no width range and corresponding coefficient are set, or if the width of a certain profile is not within the set width range, the corresponding coefficient is 1.

[0040] Step S2: Obtain the design quantity of profiles for shipbuilding.

[0041] like Figure 2 As shown, the design quantities of the profile processing include ship number, section number, profile number, specifications, material, profile length, total cutting length, scribing length, idle length, and processing / flow code. The processing / flow code is used to characterize the process flow stage and process method of profile processing. The design quantities of profile processing for each section of a single ship can be extracted from the design system SPDM (Shipbuilding Product Data Management System) or imported from an Excel file with a fixed format for profile processing.

[0042] Step S3: Calculate the rated working hours.

[0043] Once the standard data for profile processing quotas and the design quantity of profile processing for each section of a single ship are determined, the quota time for each profile in each section of the ship to complete the profile processing procedure can be calculated.

[0044] Step 1: Define a multidimensional array:

[0045] Type

[0046] Arr = Record of

[0047] Lx: string;

[0048] Kd1:Float;

[0049] Exp1:String;

[0050] Kd2:Float;

[0051] Exp2:String;

[0052] Kdxs:Float;

[0053] End;

[0054] TArr: Array of Arr;

[0055] Step 2: Based on the ship number for which the standard man-hours need to be calculated, obtain the shipyard area for that ship number;

[0056] Step 3: Using the ship's construction site, obtain the baseline man-hours, width range, and coefficients for cold bending:

[0057] (1) Based on the shipyard, the cold bending benchmark time is obtained from the quota standard for profile processing and assigned to the variable Jzgs_lw;

[0058] (2) Assign the width range and coefficient expression to the variable Expr;

[0059] (3) If the length of variable Expr is 0, that is, the width range and coefficient are not defined, then Kdxs = 1, and jump to step (12) in the third step;

[0060] (4) 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 width range and coefficient before the semicolon ";" to variable S1, and delete the first semicolon ";" and all characters before it in Expr.

[0061] (5) Determine whether each character of S1 is a number from "0" to "9", or "(", "[", ")", "]", ".", ",". If not, the definition of the width range and coefficient of the segment is incorrect, and jump to step (4) in the third step.

[0062] (7) Determine whether the first character of S1 is “(” or “[”. If not, the definition of the width range and coefficient of the segment is incorrect. Jump to step (12) in the third step. 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.

[0063] (8) Store the character before “,” into array TArr’s Kd1, and delete “,” and all characters before it from S1.

[0064] (9) Store the character before “)” or “]” into array TArr’s Kd2, and store “<” or “<=” into array TArr’s Exp2. Delete “)” or “]” and all characters before it from S1.

[0065] (10) Store the remaining characters of S1 into array TArr's Kdxs, thus completing a parsing operation of the width range and coefficients.

[0066] (11) If the length of Expr is still greater than 0, jump to step (5) in the third step and continue to analyze the width range and coefficients of the next segment.

[0067] (12) End the analysis operation of the width range and coefficient of cold bending.

[0068] Step 4: Using the ship's construction site, obtain the baseline man-hours, width range, and coefficients for the angled section:

[0069] (1) Based on the shipyard, obtain the benchmark working hours for angle bending from the quota standard for profile processing and assign them to the variable Jzgs_zj;

[0070] (2) Assign the width range and coefficient expression to the variable Expr;

[0071] (3) If the length of variable Expr is 0, that is, the width range and coefficient are not defined, then Kdxs = 1, and jump to step (12) in step 4;

[0072] (4) 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 width range and coefficient before the semicolon ";" to variable S1, and delete the first semicolon ";" and all characters before it in Expr.

[0073] (5) Determine whether each character of S1 is a number from "0" to "9", or "(", "[", ")", "]", ".", ",". If not, the definition of the width range and coefficient of the segment is incorrect, and jump to step (4) in step four.

[0074] (7) Determine whether the first character of S1 is “(” or “[”. If not, the definition of the width range and coefficient of the segment is incorrect. Jump to step (12) in step 4. 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.

[0075] (8) Store the character before “,” into array TArr’s Kd1, and delete “,” and all characters before it from S1.

[0076] (9) Store the character before “)” or “]” into array TArr’s Kd2, and store “<” or “<=” into array TArr’s Exp2. Delete “)” or “]” and all characters before it from S1.

[0077] (10) Store the remaining characters of S1 into array TArr's Kdxs, thus completing a parsing operation of the width range and coefficients.

[0078] (11) If the length of Expr is still greater than 0, jump to step (5) in the fourth step and continue to analyze the width range and coefficients of the next segment.

[0079] (12) End the analysis operation of the width range and coefficient of the angle.

[0080] Step 5: Load the design quantity data for the profile processing of each section of the ship. Based on the width and processing gauge of the profile, obtain the coefficient for the width range, and then calculate the standard man-hour for the profile processing procedure = cold bending reference man-hour (Jzgs_lw) × width coefficient (Kdxs_lw) or angle bending reference man-hour (Jzgs_zj) × width coefficient (Kdxs_zj).

[0081] (1) Obtain the width (Kd) and processing code of the profile;

[0082] (2) Loop through the array TArr(For i:=Low(TArr)To High(TArr)Do);

[0083] (3) If the current Exp1 of array TArr is ">", Exp2 is "<", and variable Kd is greater than array Kd1 and less than array Kd2, satisfying the width range, obtain the cold bending width range coefficient and assign it to variable Kdxs_lw or the corner width range coefficient and assign it to variable Kdxs_zj, jump out of the loop to traverse the array, and go to step 5 (8) to calculate the processing quota time of the current profile;

[0084] (4) If the current Exp1 of array TArr is ">", Exp2 is "<=", and variable Kd is greater than array Kd1 and less than or equal to array Kd2, satisfying the width range, obtain the cold bending width range coefficient and assign it to variable Kdxs_lw or the corner width range coefficient and assign it to variable Kdxs_zj, jump out of the loop to traverse the array, and go to step 5 (8) to calculate the processing quota time of the current profile;

[0085] (5) If the current Exp1 of array TArr is ">=", Exp2 is "<", and variable Kd is greater than or equal to array Kd1 and less than array Kd2, satisfying the width range, obtain the cold bending width range coefficient and assign it to variable Kdxs_lw or the corner width range coefficient and assign it to variable Kdxs_zj, jump out of the loop to traverse the array, and go to step 5 (8) to calculate the processing quota time of the current profile;

[0086] (6) If the current Exp1 of array TArr is ">=", Exp2 is "<=", and variable Kd is greater than or equal to array Kd1 and less than or equal to array Kd2, satisfying the width range, obtain the cold bending width range coefficient and assign it to variable Kdxs_lw or the corner width range coefficient and assign it to variable Kdxs_zj, jump out of the loop to traverse the array, and go to step 5 (8) to calculate the processing quota time of the current profile;

[0087] (7) If the array TArr is traversed in the loop and no satisfactory range of cold bending width or angle width is found after the comparisons in (3), (4), (5), and (6) in step 5, then assign variable Kdxs_lw = 1 or Kdxs_zj = 1.

[0088] (8) Calculate the current profile processing quota hours = Jzgs_lw*Kdxs_lw or Jzgs_zj*kdxs_zj.

[0089] like Figure 4 The figure shows the cold bending data of the H2441 ship section 102 designed and issued in a certain embodiment. The condition is that the first letter (i.e. the processing code) in the "Destination" column is "N", "Q" or "R", which means that the profile needs to be cold bent.

[0090] In the diagram, there are 13 parts (profiles) in segment 102. Only 2 parts have "N" as the first letter of their "destination". The time for cold bending processing is calculated.

[0091] The baseline working hours are obtained from the cold bending angle quota standard for profiles, Jzgs_LW = 1.37. The model specification "BP260*11" in the fifth line has a width of 260. The width system is obtained from the user-defined range and coefficient, Kdxs_LW = 1.08. The quota working hours (cold bending) = Jzgs_LW multiplied by Kdxs_LW = 1.37 * 1.08 = 1.48 (rounded to two decimal places).

[0092] like Figure 5 The figure shows the profile angle data for section 152 of ship H2441 designed and issued in one embodiment. The condition is that the first letter (i.e., processing code) in the "Destination" column is "K", which means that the profile needs to be angled.

[0093] The diagram shows 152 segments and 113 parts (profiles). Only a few parts have "K" as the first letter of their "destination" field, requiring calculation of the bending processing time.

[0094] The baseline working hours are obtained from the cold bending angle quota standard for profiles, Jzgs_ZJ = 1.07. The model specification "BP180*9" in the fourth line has a width of 180. The width system is obtained from the user-defined range and coefficient, Kdxs_ZJ = 1.08. The quota working hours (cold bending) = Jzgs_ZJ multiplied by Kdxs_ZJ = 1.07 * 1.08 = 1.16 (rounded to two decimal places).

[0095] Step 6: For the material quantity of the profiles of each section of the ship that have been loaded, repeat steps (1) to (12) of Step 3, steps (1) to (12) of Step 4 and steps (1) to (8) of Step 5 to calculate the processing quota time for each profile of each section of the ship until the cycle ends.

[0096] The above algorithm for calculating the standard working hours for profile processing yields the standard working hours for all profiles used in shipbuilding, providing a benchmark and support for work assignment, resource allocation, on-site management, labor cost settlement, and actual cost analysis.

[0097] 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 time of shipbuilding profile processing as described in any embodiment of the present invention.

[0098] 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 time of shipbuilding profile processing according to any embodiment of this invention.

[0099] 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.

[0100] 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.

[0101] That is, all the steps in the above method process are executed by the above-mentioned device (or the above-mentioned application).

[0102] This invention first analyzes the working nature of the profile processing procedure and establishes a standard time for profile processing based on the resource allocation of different construction sites. This standard includes the construction site, the baseline time, the width range, and the corresponding coefficients. Secondly, different methods are used to obtain the design quantity of profile processing for shipbuilding. By comparing the processing / flow code and width of each profile with the standard time, the corresponding cold bending baseline time and cold bending width range coefficient or angle bending baseline time and angle bending width range coefficient are obtained. Finally, the standard time spent on profile processing for each profile is calculated (standard time = cold bending baseline time × cold bending width range coefficient or angle bending baseline time × angle bending width range coefficient).

[0103] If the quota time for shipbuilding profile processing is calculated manually (more than 7,000 profiles), firstly, the collection and organization of the design quantity of profile processing is time-consuming; secondly, the acquisition of the cold bending benchmark time and cold bending width range coefficient or the angle benchmark time and angle width range coefficient for each profile is prone to errors, thus affecting the calculation result of the processing quota time (quota time = cold bending benchmark time × cold bending width range coefficient or angle benchmark time × angle width range coefficient).

[0104] The above-described method for calculating the standard working hours for profile processing yields the standard working hours for the cutting and production 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.
