Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a method and system for calculating the working hours quota of a pretreatment process of a ship structure. Background Art

[0002] With the deep integration of production among the company's factories, the trend of cross-production area construction of related products is becoming more and more frequent. However, due to the inconsistency of the current process operation quantity measurement standards and rules in each factory, the inconsistent process evaluation granularity and other problems, the production department needs to understand the quantity of work in different factories at all times when calculating the standard working hours, which makes the calculation cost of the standard working hours high. The existing unified standard working hours division for improving the calculation speed does not take into account the different production speeds in different factories, resulting in unreasonable production planning arrangements, thereby reducing production efficiency.

[0003] For the shipbuilding industry, due to the different granularity of the design quantity of each process of a single ship, faced with hundreds of thousands of records of design quantity of a single ship, and the parameter standards for calculating the standard working hours of each process are not unified, the standard working hours of each process are usually calculated manually. Manual calculation of standard working hours often relies on the experience of the staff. Not only can the correctness of the calculation results not be guaranteed, but the efficiency is also extremely low. Summary of the invention

[0004] In order to solve the above technical problems, the present invention discloses a method and system for calculating the working hours quota of a pretreatment process of a ship structure, which are used to improve the efficiency and accuracy of the working hours quota calculation.

[0084] The present embodiment discloses a method and system for calculating the labor quota for the pretreatment process of a ship structure. A universal quota labor time library is constructed to store the benchmark labor time corresponding to the plant that processes the structure, the area size range of the steel plates that can be processed by the plant, and the correction coefficients corresponding to the different area size ranges. The benchmark labor time stored in the universal quota labor time library takes into account the different production speeds of different plants to ensure the rationality of the labor quota.

[0086] Embodiment 2

[0087] This embodiment further provides a method for calculating the working hours quota of the pretreatment process of a ship structure. In this embodiment, please refer to Figure 3 , mainly including steps 301 to 305, the steps are:

[0088] Step 301: Establish a general quota man-hour library corresponding to the pre-treatment process of ship structural parts.

[0089] In this embodiment, this step mainly includes: the ship manufacturing process includes a variety of processes, such as hull manufacturing pretreatment process, hull manufacturing cutting process, hull manufacturing docking process, hull manufacturing welding / assembly / grinding process and general assembly and loading process, etc., and the hull manufacturing pretreatment process is to pretreat the structural parts used for ship manufacturing, such as plates and profiles, so that the plates or profiles meet the standards of ship manufacturing, which is convenient for a series of subsequent processes.

[0090] In the hull manufacturing pretreatment process, the objects of the pretreatment operation are mainly the steel plates in the structural parts, and the resources for steel plate pretreatment operations in different construction plants in shipbuilding are different, resulting in different working hours for steel plates of the same specifications to complete the pretreatment operations in different construction plants, and in the same construction plant, the working hours corresponding to steel plates of different specifications are also different. Therefore, based on providing a standard and universal quota working hour calculation method, this step can form a universal quota working hour library in sequence according to the quota standards in the process of establishing structural parts pretreatment.

[0091] The general standard working time database includes the construction plant area, the benchmark working time (hours / square meter), the area range and the corresponding coefficient. For details, the contents of the general standard working time database can be referred to Figure 4 ,like Figure 4As shown in the figure, when the construction plant is the Wenchong plant, the corresponding benchmark working hours are 0.0185. The area interval corresponding to the Wenchong plant and the correction coefficient corresponding to each area interval are: (0,30]1,08; (30,60]1.23; (60,200]1,35, wherein the area range interval and the corresponding coefficient can be based on the actual working hours and the size of the steel plate collected in the pre-processing operation, and the empirical estimated value can be calculated, and it can be corrected. The area range interval is represented by an open interval symbol and a closed interval symbol, refer to Figure 4 If the area of ​​a steel plate during the pretreatment process at the Wenchong plant is greater than 0 square meters and less than or equal to 30 square meters, the man-hour correction coefficient corresponding to the steel plate is 1.08; if the area of ​​a steel plate is greater than 30 square meters and less than or equal to 60 square meters, the man-hour correction coefficient corresponding to the steel plate is 1.23, and so on.

[0092] Step 302: Obtain a sample structural part to be subjected to a pretreatment process, extract process information of the sample structural part, and generate a process file according to the process information; wherein the process file includes a plurality of steel plates and the steel plate area corresponding to each steel plate.

[0093] In this embodiment, this step mainly includes: based on the information stored in the constructed universal standard working time library, it can be known that the name of the target factory where the sample structural parts are subjected to the pretreatment process and the number of steel plates included in the sample structural parts and the area of ​​each steel plate need to be obtained, thereby providing a basis for calculation of the subsequent working time quota.

[0094] Therefore, in order to ensure the accuracy of the process information extraction, the overall design of the ship will be simulated before the ship is manufactured. Therefore, this embodiment extracts the process information of the sample structural part through the hull material collection tray in the design system of the sample structural part, wherein the design system generally adopts the SPDM system, and the process information may include the ship number of the ship where the sample structural part is located, the segment number after the single ship where the sample structural part is located is segmented, the material name in the plate, the thickness of each material, the width of each material, the length of each material, the material of each material, the number of pieces of each material, the total net weight of each material, and the total gross weight of each material. Based on the fact that the main measurement object of this embodiment is the steel plate, the material in the provided process information is the steel plate in the structural part.

[0095] When extracting the thickness, width and length of the steel plate, the unit can be set to mm, and the above process information can be imported through a table of pre-processed structural parts in a fixed format to generate a process file for later call. When extracting the process information, it can be determined whether the number of pieces of the steel plate is greater than 1. If the number of pieces is greater than 1, multiple rows of steel plate data with a number of pieces of 1 are automatically split, and the area calculation formula preset in the fixed format is used to calculate the area of ​​each steel plate. For details, please refer to Figure 5 , is the content of a process file provided in this embodiment, wherein the area calculation formula in the fixed format is: width ╳ length ╳ 2 ÷ 1000000; the unit of the area is square meters, as shown in Figure 5 In the 2nd and 3rd rows, and the 5th and 6th rows, the steel plates in the 2nd and 3rd rows or the 5th and 6th rows are all the same type of steel plates and are split into single-row steel plate information.

[0096] Step 303: Determine a target factory area for performing a pretreatment process on the sample structural part, and obtain the benchmark working hours, area interval and corresponding correction coefficient corresponding to the target factory area by querying the general quota working hours database.

[0097] In this embodiment, the step is: the ship number of the ship where the sample structure is located can be determined according to the received ship information, and the target factory area for the pretreatment process of the sample structure can be determined according to the ship number. Figure 5 It can be seen that the ship number corresponding to the sample structure is H2453, and according to the propagation information, the construction site of H2453 is Wenchong. Figure 4 The general quota working hour standard corresponding to the Wenchong factory area shown includes the benchmark working hours, area intervals and corresponding correction coefficients corresponding to the Wenchong factory area.

[0098] Step 304: loop through the process file and mark the corresponding correction coefficient for each steel plate in the sample structure.

[0099] In this embodiment, this step is mainly as follows: in order to assign a corresponding correction coefficient to each steel plate in the process file, ensure that each steel plate is not missed, and realize the automation of marking, this step can set the program to automatically execute the marking process of the correction coefficient.

[0100] In one embodiment, this step first defines a multidimensional array to parse several area intervals corresponding to the target plant area and convert them into computer language to mark the coefficients of the steel plate later; wherein the multidimensional array is:

[0101] Type

[0102] Arr=Record of

[0103] Mj1:F l oat;

[0104] Exp1:Str i ng;

[0105] Mj2:F l oat;

[0106] Exp2:Str i ng;

[0107] Mjxs:F l ​​oat;

[0108] End;

[0109] TArr:Array of Arr;

[0110] The plurality of area intervals are analyzed cyclically according to the multidimensional array; specifically, the steps of analyzing the plurality of area intervals corresponding to the target plant area and the coefficients corresponding to each area interval by the multidimensional data are as follows:

[0111] (1) Assign the area interval corresponding to the target plant area and the corresponding correction coefficient to the variable Expr, wherein Expr includes Exp1 and Exp2; if the length of Expr is 0, it is determined that the target plant area has no defined area range interval and coefficient, and then assign Mjxs=1, and jump to step (5);

[0112] (2) If the length of Expr is greater than 0, determine whether there is a semicolon. If not, assign Expr to variable S1 and set Expr to empty. If there is a semicolon, assign the area range and coefficient before the semicolon to variable S1, and delete the first semicolon and all characters before it in Expr.

[0113] (3) Determine whether each character of S1 is a number from 0 to 9, or an open interval symbol or a closed interval symbol. If not, the definition of the area range interval and coefficient is incorrect, and jump to the previous step; determine whether the first character of S1 is a greater than symbol or a greater than or equal to symbol. If not, the definition of the area range interval and coefficient is incorrect, and jump to step (5). If so, an item is added to the array TArr, and the greater than symbol or the greater than or equal to symbol is stored in the Exp1 of the array TArr, and the first character of S1 is deleted; the character before the comma is stored in the Mj1 of the array TArr, and the comma and all the characters before it of S1 are deleted; the character before the less than symbol or the less than or equal to symbol is stored in the Mj2 of the array TArr, and the less than symbol or the less than or equal to symbol is stored in the Exp2 of the array TArr, and the less than symbol or the less than or equal to symbol and all the characters before it of S1 are deleted; the remaining characters of S1 are stored in the Mjxs of the array TArr, thereby completing an area range interval and coefficient parsing operation.

[0114] (4) If the length of Expr is still greater than 0, jump to step (2) and continue with the area range interval and coefficient analysis of the next section.

[0115] (5) Complete the analysis of area range intervals and coefficients.

[0116] Specifically, refer to the multidimensional data loop traversal defined above as follows Figure 4 The custom area range and corresponding area coefficient in the target factory area shown in the figure are first assigned to the variable Expr in the multidimensional array with the interval and coefficient (0,30]1.08; (30,60]1.23; (60,200]1.35 corresponding to the Wenchong factory area;

[0117] Expr=(0,30]1.08;(30,60]1.23;(60,200]1.35. At this time, if there is a semicolon symbol in Expr, the area range interval and coefficient before the semicolon symbol are assigned to variable S1=(0,30]1.08, and the first semicolon symbol and all characters before it in Expr are deleted. At this time, variable Expr=(30,60]1.23;(60,200]1.35. At this time, if the variable Expr also includes a semicolon symbol, the area range interval and coefficient before the semicolon symbol are continued to be assigned to variable S1, and the first semicolon symbol and all characters before it in Expr are deleted until Expr is empty.

[0118] Then, according to the analyzed area interval and corresponding coefficient, the multidimensional array is used to loop through the process file corresponding to the sample structure, and the area corresponding to each steel plate in the process file is assigned to the variable Mj, and the multidimensional array TArr (For i: = Low (TArr) To H i is looped through gh(TArr)Do); if the current Exp1 of the array TArr is a greater than sign, Exp2 is a less than sign, and the variable Mj is greater than the array Mj1 and less than the array Mj2, the area range interval is satisfied, and the area interval coefficient is obtained and assigned to the variable Mjxs, and the loop traversal of the array is exited; if the current Exp1 of the array TArr is a greater than sign, Exp2 is a less than or equal to sign, and the variable Mj is greater than the array Mj1 and less than or equal to the array Mj2, the area range interval is satisfied, and the area interval coefficient is obtained and assigned to the variable Mjxs, and the loop traversal of the array is exited; if the current Exp1 of the array TArr is a greater than or equal to sign, Exp2 is a less than sign, and the variable Mj is greater than or equal to the array Mj1 and less than the array Mj2, the area range interval is satisfied, and the area interval coefficient is obtained and assigned to the variable Mjxs, and the loop traversal of the array is exited. If the current Exp1 of the array TArr is greater than or equal to the symbol, Exp2 is less than or equal to the symbol, and the variable Mj is greater than or equal to the array's Mj1 and less than or equal to the array's Mj2, the area range interval is satisfied, the area interval coefficient is obtained and assigned to the variable Mjxs, and the loop traversing the array is exited.

[0119] If the array TArr is traversed in a loop and no satisfactory area range interval is found through the above area interval comparison, the variable Mjxs=1 is assigned.

[0120] Specifically, Figure 5 Taking the steel plate area corresponding to each steel plate in the process file shown as an example, Mj=26.28 in the first cycle, Mj=43.2 in the second and third cycles, and so on. Then the array TArr is traversed in a loop (For i:=Low(TArr)To High(TArr)Do), so when the steel plate area is 26.28, the area interval coefficient is 1.08; when the steel plate area is 43.2, the area interval coefficient is 1.23, and so on, to obtain the area coefficient corresponding to each steel plate area.

[0121] Step 305: According to the number of steel plates in the sample structural part, the steel plate area of ​​each steel plate, the correction coefficient and the reference formula, the labor quota of the sample structural part is calculated to obtain the labor hours of the sample structural part.

[0122] In this embodiment, this step mainly includes: loading the steel plate area of ​​each steel plate in the sample structural part, the corresponding correction coefficient and the benchmark working hours of the target factory area, and calculating the standard working hours corresponding to each steel plate, wherein the calculation formula of the standard working hours is: steel plate area ╳ benchmark working hours ╳ area coefficient.

[0123] In this embodiment, by looping through each steel plate in the sample structure, the area assignment variable Mj, the area coefficient Mjxs and the benchmark formula Jzgs of the target plant area are obtained, and the pretreatment quota working hours of each steel plate are calculated = Mj*Jzgs*Mjxs.

[0124] The quota working hours for the sample structural parts are calculated based on the quota working hours for pretreatment of each steel plate.

[0125] The present embodiment provides a method for calculating the quota of working hours for the pretreatment process of a ship structure. First, the working properties of the pretreatment sample structure are analyzed, and the quota working hour standards for the pretreatment structure are established according to the resource allocation of different construction plants, including the construction plant, the base working hours, the area range interval and the corresponding coefficients. Then, the design quantity of the pretreatment structure for ship construction is extracted, and the corresponding base working hours and area range interval coefficients are obtained by comparing the design quantity with the quota working hour standards. Finally, the quota working hours spent on pretreatment of each steel plate are calculated (quota working hours = steel plate area ╳ base working hours ╳ area range interval coefficient), so as to realize the automation of the calculation of the quota of working hours and improve the efficiency and accuracy of the calculation.
