Description

Technical Field

[0001] This application relates to the field of ship design technology, and in particular to a method and system for intelligent layout of pipelines for ship design. Background Technology

[0002] The interior of a ship is filled with pipelines that serve various systems, such as fuel systems, cooling systems, and ballast systems. These pipelines constitute the ship's "circulatory system," and the rationality of their design directly affects the ship's construction cost, operating efficiency, and ease of maintenance.

[0003] In current ship piping design, designers typically plan the piping path in 3D design software based on known pipe start and end points, using structural models of ship compartments, equipment layout models, and other existing system models. This process relies heavily on the designer's understanding and imagination of 3D space. Through manual observation, judgment, and operation, they find a reasonable path within the complex ship space that connects the start and end points, avoids all obstacles, and meets engineering specifications.

[0004] The aforementioned technologies not only require designers to have a high level of experience, but also involve a huge workload due to the large number of pipes inside the pipeline. Therefore, the current methods are not convenient for efficiently and accurately designing the required pipeline layout schemes, and there is still room for improvement. Summary of the Invention

[0005] To facilitate efficient and accurate design of pipeline layout schemes, this application provides an intelligent pipeline layout method and system for ship design.

[0006] Firstly, this application provides a method for intelligent layout of pipelines for ship design, employing the following technical solution: A method for intelligent layout of piping in ship design includes: Obtain the initial ship model and pipeline requirement parameters, including the pipeline output start point, pipeline input end point, and pipeline constraints. In the initial model of the ship, a single simulated pipeline is constructed based on the pipeline output start point and pipeline input end point of each pipeline. The effective simulated pipeline is determined by analyzing the single simulated pipeline and pipeline constraints. Construct a valid set of pipes based on all valid simulated pipes, and randomly select one valid simulated pipe from each valid set to combine them to construct a simulated layout scheme; Under the simulated layout scheme, the negotiation points are determined based on each effective simulated pipeline, and the number of individual negotiations is determined by counting the negotiation points. Under pipeline constraints, the number of permitted negotiations is determined, and a simulated layout scheme in which the number of negotiations for each individual unit is not greater than the corresponding number of permitted negotiations is defined as an effective layout scheme. Determine a reasonable layout scheme from the effective layout schemes and output the reasonable layout scheme to the preset management terminal.

[0007] Optionally, after the negotiation points are determined, the intelligent layout method for ship piping in design also includes: The scope of prohibited negotiations is determined based on pipeline constraints and the initial ship model. Determine whether there exists at least one valid simulated pipeline with a point of interaction that falls within the corresponding no-interaction zone; If there is no negotiation point of at least one effective simulated pipeline that is within the corresponding negotiation prohibition range, then the number of individual negotiations is determined based on the negotiation points to define an effective layout scheme; If at least one valid simulated pipeline has a negotiation point that falls within the corresponding negotiation prohibition range, then the current corresponding simulated layout scheme will be eliminated.

[0008] Optionally, the steps for determining the scope of the negotiation prohibition based on pipeline constraints and the initial ship model include: The ship's local areas are divided based on the initial ship model, and the pipeline connection type is determined based on the pipeline output start point and pipeline input end point. Construct a historical interval on a preset timeline with the current time point as the endpoint and a width of a preset historical duration, and determine the area where negotiations exist within the historical interval based on the pipeline connectivity type; In all ship local areas, ship local areas that are not areas for negotiation will be designated as historical prohibited areas; Based on pipeline constraints, local prohibited areas are determined in the initial ship model, and these local prohibited areas are combined with historical prohibited areas to construct the negotiation prohibited area.

[0009] Optionally, after the effective layout scheme is determined, the intelligent layout method for pipelines in ship design also includes: The effective simulation length is determined based on each effective simulated pipeline in each effective set of pipelines, and the minimum effective simulation length in a single effective set of pipelines is defined as the effective lower limit length; In the effective layout scheme, the excess length of the pipeline is determined by calculating the difference between the effective simulated length of each selected effective simulated pipeline and the corresponding effective lower limit length. Effective simulated pipelines with excess length exceeding the preset permissible excess length are defined as effective over-limit pipelines, and the number of pipelines exceeding the limit is determined by counting the effective over-limit pipelines. Determine whether the number of pipelines exceeding the limit is greater than the preset permissible number of exceeding the limit; If the number of pipelines exceeding the limit is not greater than the permitted number of pipelines exceeding the limit, then the currently determined effective layout scheme shall be maintained. If the number of pipelines exceeding the limit is greater than the permitted number of pipelines exceeding the limit, the currently determined effective layout scheme will be eliminated.

[0010] Optionally, it also includes a step for determining the number of permits exceeding the limit, which includes: The excess length and permissible excess length of the pipeline are used to calculate and determine the excess ratio under the effective excess pipeline conditions; The number of adjustments required to exceed the limit is determined based on the preset adjustment matching relationship, corresponding to the proportion of excess limits. The permitted over-limit quantity is determined by calculating based on the preset fixed over-limit quantity and the over-limit adjustment quantity.

[0011] Optionally, the steps to determine a reasonable layout scheme from the effective layout schemes include: The effective simulation length corresponding to the selected effective simulation pipeline is defined as the specific length of the single unit; The pipe material type is obtained based on the pipe connection type, and the corresponding material unit price is determined according to the preset quotation matching relationship. The overall quotation parameters are determined by calculating based on the specific length of the unit and the corresponding material unit price. The overall pipeline length is determined by summing up all the specific lengths of each unit. The reasonable value of the scheme is determined by calculation and analysis based on the overall quotation parameters and the overall pipeline length. The effective layout scheme with a reasonable value greater than the preset benchmark reasonable value is determined as the reasonable layout scheme.

[0012] Optionally, the steps for outputting the reasonable layout plan to the preset management terminal include: Randomly select a reasonable layout scheme as the primary layout scheme, and define the remaining reasonable layout schemes as secondary layout schemes; The similarity coefficient of the main layout scheme and the secondary layout scheme is determined by comparison and analysis. The secondary layout scheme with a similarity coefficient greater than the preset easy change coefficient is defined as a feasible change scheme of the current main layout scheme, and the reasonable value of the feasible change scheme is defined as the reasonable change value. The adjustment value is determined by calculating the reasonable value of each change, and the scheme selection value is determined by calculating the reasonable value of the main layout scheme and the adjustment value of the change. The reasonable layout schemes are sorted according to the scheme selection value from largest to smallest to determine the output order, and then the reasonable layout schemes are output to the management terminal according to the output order.

[0013] Secondly, this application provides an intelligent pipeline layout system for ship design, which adopts the following technical solution: A smart piping layout system for ship design, comprising: The acquisition module is used to acquire the initial model of the ship and the pipeline requirement parameters, including the pipeline output start point, the pipeline input end point, and the pipeline constraint conditions. The processing module, connected to the acquisition module, is used for information storage and processing; The processing module constructs individual simulated pipelines in the initial ship model based on the pipeline output start point and pipeline input end point of each pipeline, and analyzes the individual simulated pipelines and pipeline constraints to determine the effective simulated pipelines. The processing module constructs a valid set of pipelines based on all valid simulated pipelines, and randomly selects a valid simulated pipeline from each valid set to combine them to construct a simulated layout scheme; The processing module determines the negotiation points based on each effective simulated pipeline under the simulated layout scheme, and counts the negotiation points to determine the number of individual negotiations; The processing module determines the number of permissible negotiations under pipeline constraints and defines the simulated layout scheme in which the number of negotiations for each individual unit is not greater than the corresponding number of permissible negotiations as the effective layout scheme; The processing module determines a reasonable layout scheme from the valid layout schemes and outputs the reasonable layout scheme to the preset management terminal.

[0014] In summary, this application includes at least one of the following beneficial technical effects: During the design of ship piping, the system can automatically analyze the ship's conditions to simulate the layout of each pipeline, thereby automatically determining a suitable pipeline layout scheme, which facilitates efficient and accurate design of the pipeline layout scheme. During the automatic pipeline layout process, factors such as pipeline intersections and lengths are fully considered to determine a suitable layout scheme. When multiple pipeline layout options are output, the correlation between the options is fully considered so that the options with higher probability of selection are set first, making it easier for users to select options.

[0016] Figure 2 This is a flowchart of the module for intelligent pipeline layout methods in ship design. Detailed Implementation

[0017] To make the purpose, technical solution, and advantages of this application clearer, the following is combined with Figures 1-2The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0018] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0019] This application discloses an intelligent layout method for pipelines in ship design, referring to... Figure 1 The method and process of intelligent pipeline layout for ship design includes the following steps: Step S100: Obtain the initial ship model and pipeline requirement parameters, including the pipeline output start point, pipeline input end point, and pipeline constraints.

[0020] The initial ship model is the ship design model imported by the designer without piping. Piping layout needs to be done on this model. Piping requirement parameters are the parameters required for the pipes to be laid out. The designer enters the information according to the situation of each pipe to be designed and laid. Specifically, these include the pipe output start point, the pipe input end point, and the pipe constraint conditions. The pipe output start point is the starting point of a single pipe, the pipe input end point is the ending point of a single pipe, and the pipe constraint conditions are the requirements for designing the current pipeline, such as the length not exceeding a certain number of meters, the number of bends not allowed, and the requirement not to pass through specific areas, etc. The specifics are determined by the designer based on the actual situation.

[0021] Step S101: Construct individual simulated pipelines in the initial model of the ship based on the pipeline output start point and pipeline input end point of each pipeline, and analyze the individual simulated pipelines and pipeline constraints to determine the effective simulated pipelines.

[0022] A single simulated pipeline is a pipeline that extends from the pipeline output point to the pipeline input point, and this pipeline is only located in the area where pipelines can be drawn in the initial model of the ship; an effective simulated pipeline is a single simulated pipeline that meets the pipeline constraints of the current pipeline.

[0023] Step S102: Construct a valid set of pipes based on all valid simulated pipes, and randomly select one valid simulated pipe from each valid set of pipes to combine them to construct a simulated layout scheme.

[0024] The effective set of pipelines refers to the set of pipelines that can be designed under the same pipeline requirement parameters. By randomly selecting effective simulated pipelines, the design of each pipeline can be simulated. The simulated layout scheme constructed at this time is the simulated scheme in which all pipelines are designed inside the ship.

[0025] Step S103: Under the simulated layout scheme, determine the negotiation points according to each effective simulated pipeline, and count the negotiation points to determine the number of individual negotiations.

[0026] Interaction point refers to the location where an effective simulated pipeline crosses, and the number of individual interactions refers to the number of interaction points that a single effective simulated pipeline has under the simulated layout scheme.

[0027] Step S104: Determine the permissible negotiation quantity under pipeline constraints, and define the simulated layout scheme in which the negotiation quantity of each individual unit is not greater than the corresponding permissible negotiation quantity as the effective layout scheme.

[0028] The permitted number of negotiations is the maximum number of negotiation points allowed in the current pipeline. This data is input by the designer in advance along with the pipeline constraints. When the number of negotiations for each individual unit is not greater than the corresponding permitted number of negotiations, it means that the current simulated layout scheme meets the current pipeline layout requirements. Therefore, it is defined as a valid layout scheme to distinguish between different simulated layout schemes and facilitate subsequent analysis.

[0029] Step S105: Determine a reasonable layout scheme from the valid layout schemes and output the reasonable layout scheme to the preset management terminal.

[0030] A reasonable layout scheme is a scheme that meets the daily layout requirements of management. This scheme can be unique or multiple. The reasonable layout scheme can be randomly selected from the valid layout schemes, or it can be determined through the method of steps S600-S604. By outputting the reasonable layout scheme to the management terminal, the designer can observe and check the automatically designed pipeline layout scheme, thereby facilitating efficient and accurate design of the pipeline layout scheme.

[0031] Once the negotiation points are determined, the intelligent layout method for ship piping in design also includes: Step S200: Determine the scope of prohibited negotiations based on pipeline constraints and the initial ship model.

[0032] The prohibited negotiation range refers to the area on the pipeline where the negotiation point cannot be located, and the specific range is determined according to steps S300-S303.

[0033] Step S201: Determine whether there exists at least one valid simulated pipeline with a negotiation point within the corresponding negotiation prohibition range.

[0034] The purpose of the judgment is to determine whether there are any negotiation points within the prohibited negotiation range under the current simulated layout scheme, that is, to determine whether the current simulated layout scheme can meet the requirements.

[0035] Step S2011: If there is no effective simulated pipeline with a negotiation point within the corresponding negotiation prohibition range, then determine the number of individual negotiations based on the negotiation points to define an effective layout scheme.

[0036] When there is no effective simulated pipeline with any negotiation point within the corresponding negotiation prohibition range, it means that all negotiation points are not within the negotiation prohibition range, that is, the current simulation layout scheme meets the requirements, so the subsequent analysis can proceed normally.

[0037] Step S2012: If there is at least one valid simulated pipeline with a negotiation point that is within the corresponding negotiation prohibition range, then the current corresponding simulated layout scheme is eliminated.

[0038] When at least one valid simulated pipeline has an intersection point within the corresponding prohibited intersection range, it indicates that the current simulated layout scheme cannot meet the requirements. Therefore, it is eliminated to reduce the subsequent analysis of invalid simulated layout schemes, thereby reducing the amount of data analysis and improving pipeline layout efficiency.

[0039] The steps for determining the prohibited negotiation area based on pipeline constraints and the initial ship model include: Step S300: Divide the local area of ​​the ship according to the initial ship model, and determine the pipeline connection type according to the pipeline output start point and pipeline input end point.

[0040] The local area of ​​a ship refers to the various areas of the ship in the initial model of the ship. It can be determined according to the name of each area in the initial model of the ship, such as the bridge, etc. The pipeline connection type refers to the type of pipeline that outputs from the pipeline output starting point and inputs from the pipeline input ending point. The definition of the pipeline connection type makes it easy to distinguish each pipeline.

[0041] Step S301: Construct a historical interval on the preset timeline with the current time point as the endpoint and the width as the preset historical duration, and determine the area where the negotiation exists in the historical interval according to the pipeline connection type.

[0042] The timeline is a coordinate axis formed by combining various time points. This timeline points from the time points that have already passed to the time points that have not yet been reached, with the time points that have already passed being on the left, i.e., the beginning. The historical duration is the duration set by the staff to acquire and analyze the design data of each ship under historical conditions. By constructing historical intervals, it is possible to acquire and analyze the data within the historical duration. The negotiation area is the area where negotiation points have occurred under the current pipeline connection type of the ship's pipeline design in the historical interval.

[0043] Step S302: In all ship local areas, identify ship local areas that are not areas where negotiations exist as historical prohibited areas.

[0044] If, within a historical timeframe, there are no points of interaction between the current pipelines and any local area of ​​the ship, it indicates that, according to the designer's requirements, no points of interaction are allowed in that local area of ​​the ship. Therefore, it can be defined as a historical prohibited area.

[0045] Step S303: Determine the local prohibited areas in the initial ship model based on the pipeline constraints, and combine the local prohibited areas with the historical prohibited areas to construct the negotiation prohibited range.

[0046] The local prohibited area is the area that the current pipeline's interaction point cannot be located in, as input by the staff before the design based on the pipeline constraints. At this time, the union of the local prohibited area and the historical prohibited area is the area that the current pipeline's interaction point cannot be located in, which is also the interaction prohibited range.

[0047] Once an effective layout scheme is determined, the intelligent layout method for pipelines in ship design also includes: Step S400: Determine the effective simulation length in each effective set of pipelines based on each effective simulated pipeline, and define the minimum effective simulation length in a single effective set of pipelines as the effective lower limit length.

[0048] The effective simulation length is the length of the effective simulated pipeline. By defining the effective lower limit length, the shortest pipeline length required under the current pipeline connection type is identified and distinguished, which facilitates subsequent analysis.

[0049] Step S401: In the effective layout scheme, calculate the difference between the effective simulated length of each selected effective simulated pipeline and the corresponding effective lower limit length to determine the redundant pipeline length.

[0050] The excess length of the pipeline is the effective simulated length minus the corresponding effective lower limit length.

[0051] Step S402: Define the effective simulated pipelines with excess length greater than the preset permissible excess length as effective over-limit pipelines, and count the effective over-limit pipelines to determine the number of pipelines exceeding the limit.

[0052] Permitted excess length refers to the maximum excess length of a pipe that can occur when the length of the pipe is not much longer than the effective lower limit length and there is no waste of materials. Pipes that exceed the limit by a large margin are identified by defining effective excess pipes. The number of pipes exceeding the limit refers to the number of effective excess pipes in an effective layout scheme.

[0053] Step S403: Determine whether the number of pipelines exceeding the limit is greater than the preset permissible number of pipelines exceeding the limit.

[0054] The permissible over-limit quantity is the maximum number of pipes allowed to exceed the limit under a single valid layout scheme. This value can be a fixed value or determined through step S502. The purpose of the judgment is to determine whether the current valid layout scheme meets the requirements.

[0055] Step S4031: If the number of pipes exceeding the limit is not greater than the permissible number of pipes exceeding the limit, then maintain the currently determined effective layout scheme.

[0056] When the number of pipelines exceeding the limit is not greater than the permissible number of pipelines exceeding the limit, it means that the current effective layout scheme meets the requirements, and it can be maintained at this time.

[0057] Step S4032: If the number of pipelines exceeding the limit is greater than the permitted number of pipelines exceeding the limit, then the currently determined valid layout scheme will be eliminated.

[0058] When the number of pipelines exceeding the limit is greater than the permitted number of pipelines exceeding the limit, it means that the current effective layout scheme cannot meet the requirements, which is likely to result in excessive waste of materials. Therefore, the corresponding effective layout scheme can be eliminated, which will facilitate the determination of a suitable pipeline layout scheme in the future.

[0059] It also includes a step for determining the number of permits exceeding the limit, which includes: Step S500: Under the effective over-limit pipeline, calculate based on the excess length of the pipeline and the permissible excess length to determine the excess over-limit ratio.

[0060] The excess / over-limit ratio is the ratio of excess pipeline length to permissible excess length.

[0061] Step S501: Determine the number of excess adjustments corresponding to the excess proportion based on the preset adjustment matching relationship.

[0062] The over-limit adjustment quantity is the quantity value used to adjust the permissible over-limit quantity. The larger the proportion of excess over-limit, the more material waste there is in the current pipeline. In other words, the permissible over-limit quantity should be appropriately reduced to meet the overall material cost requirements. Therefore, the corresponding over-limit adjustment quantity should be larger. The adjustment matching relationship between the two is determined by the staff in advance through multiple tests, which will not be elaborated here.

[0063] Step S502: Calculate and determine the permitted over-limit quantity based on the preset fixed over-limit quantity and the over-limit adjustment quantity.

[0064] The fixed over-limit quantity is the number of pipes that can theoretically exceed the limit, as set by the staff. The permissible over-limit quantity that meets the requirements can be obtained by subtracting all over-limit adjustment quantities from the fixed over-limit quantity.

[0065] The steps to determine a reasonable layout scheme from the effective layout schemes include: Step S600: Define the effective simulation length corresponding to the selected effective simulation pipeline as the specific length of the unit.

[0066] By defining specific lengths for individual units, different effective simulation lengths can be identified and distinguished, facilitating subsequent analysis.

[0067] Step S601: Obtain the pipe material type according to the pipe connection type, and determine the corresponding material unit price according to the preset quotation matching relationship.

[0068] Pipeline material type refers to the type of material required for the actual laying of the current pipeline connection type. This data can be entered in advance by the designer along with the pipeline constraints. Material unit price is the cost price required for the material type of pipeline per unit length. The price matching relationship between the two is entered and stored in advance by the staff.

[0069] Step S602: Calculate and determine the overall quotation parameters based on the specific length of the unit and the corresponding material unit price.

[0070] The overall quotation parameters are the sum of the unit lengths of all pipelines multiplied by the corresponding material unit quotations, which gives the cost required for the current pipeline layout.

[0071] Step S603: Summate all the unit lengths to determine the overall pipeline length.

[0072] The total pipeline length is the sum of all unit lengths, and this length can indirectly reflect the difficulty of actual pipeline construction.

[0073] Step S604: Calculate and analyze the overall quotation parameters and overall pipeline length to determine the reasonable value of the scheme, and determine the effective layout scheme with a reasonable value greater than the preset benchmark reasonable value as the reasonable layout scheme.

[0074] The reasonable value of a scheme refers to the parameter value that reflects whether the current scheme is reasonable. The specific calculation formula is as follows: ,in The reasonable value of the plan, For overall pricing parameters, This refers to the total length of the pipeline. The weighted parameter is used to reflect the importance of the quotation in the analysis of the reasonableness of the proposed solution. The weighted parameter reflects the importance of construction difficulty in the analysis of the rationality of the plan; the benchmark rational value is the minimum reasonable value of the plan that the staff set when the plan is considered reasonable. At this time, the reasonable layout plan can be better determined by comparing the reasonable value of the plan with the benchmark rational value.

[0075] The steps for outputting the reasonable layout plan to the preset management terminal include: Step S700: Randomly select a reasonable layout scheme as the primary layout scheme, and define the remaining reasonable layout schemes as secondary layout schemes.

[0076] Different reasonable layout schemes are distinguished by defining primary and secondary layout schemes, which facilitates subsequent analysis.

[0077] Step S701: Compare and analyze the main layout scheme and the secondary layout scheme to determine the scheme similarity coefficient, and define the secondary layout scheme with a scheme similarity coefficient greater than the preset easy change coefficient as a feasible change scheme of the current main layout scheme, and define the reasonable value of the feasible change scheme as the reasonable change value.

[0078] The scheme similarity coefficient is a parameter value that reflects the degree of similarity between two reasonable layout schemes. Different weight parameters can be assigned to each pipeline connection type, and the overlap ratio of pipelines of the same pipeline connection type can be determined. The scheme similarity coefficient is determined by multiplying the weight parameter by the corresponding overlap ratio and then adding them all together. The ease of change coefficient is the minimum scheme similarity coefficient set by the staff to make adjustments between the two schemes for the designers. At this time, feasible change schemes are defined to distinguish secondary layout schemes that can be changed from the main layout scheme, which facilitates subsequent analysis. Similarly, reasonable change values ​​are defined to distinguish reasonable values ​​of different schemes, which facilitates analysis.

[0079] Step S702: Calculate the change adjustment value based on the reasonable value of each change, and calculate the scheme selection value based on the reasonable value of the main layout scheme and the change adjustment value.

[0080] The change adjustment value is the sum of all reasonable change values, and the scheme selection value is a value that reflects the degree to which the current scheme is most convenient for users to choose and the best effect is achieved. The larger the value, the better the corresponding scheme is, and the easier it is to adjust after the user selects it. It is determined by multiplying the reasonable value of the scheme by the weight of the scheme selection value, and adding the change adjustment value by the weight of the change adjustment value.

[0081] Step S703: Sort each reasonable layout scheme according to the scheme selection value from largest to smallest to determine the scheme output order, and output each reasonable layout scheme to the management terminal according to the scheme output order.

[0082] The output order of the schemes is the order in which the reasonable layout schemes are sorted according to the scheme selection value from largest to smallest. At this time, the reasonable layout schemes are output according to the output order of the schemes so that the designers can choose them later.

The reasonable value of the scheme is determined by calculation and analysis based on the overall quotation parameters and the overall pipeline length. The effective layout scheme with a reasonable value greater than the preset benchmark reasonable value is determined as the reasonable layout scheme.

7. The intelligent layout method for ship piping in claim 6, characterized in that, The steps for outputting the reasonable layout plan to the preset management terminal include: Randomly select a reasonable layout scheme as the primary layout scheme, and define the remaining reasonable layout schemes as secondary layout schemes; The similarity coefficient of the main layout scheme and the secondary layout scheme is determined by comparison and analysis. The secondary layout scheme with a similarity coefficient greater than the preset easy change coefficient is defined as a feasible change scheme of the current main layout scheme, and the reasonable value of the feasible change scheme is defined as the reasonable change value. The adjustment value is determined by calculating the reasonable value of each change, and the scheme selection value is determined by calculating the reasonable value of the main layout scheme and the adjustment value of the change. The reasonable layout schemes are sorted according to the scheme selection value from largest to smallest to determine the output order, and then the reasonable layout schemes are output to the management terminal according to the output order.

8. A smart piping layout system for ship design, characterized in that, include: The acquisition module is used to acquire the initial model of the ship and the pipeline requirement parameters, including the pipeline output start point, the pipeline input end point, and the pipeline constraint conditions. The processing module, connected to the acquisition module, is used for information storage and processing; The processing module constructs individual simulated pipelines in the initial ship model based on the pipeline output start point and pipeline input end point of each pipeline, and analyzes the individual simulated pipelines and pipeline constraints to determine the effective simulated pipelines. The processing module constructs a valid set of pipelines based on all valid simulated pipelines, and randomly selects a valid simulated pipeline from each valid set to combine them to construct a simulated layout scheme; The processing module determines the negotiation points based on each effective simulated pipeline under the simulated layout scheme, and counts the negotiation points to determine the number of individual negotiations; The processing module determines the number of permissible negotiations under pipeline constraints and defines the simulated layout scheme in which the number of negotiations for each individual unit is not greater than the corresponding number of permissible negotiations as the effective layout scheme; The processing module determines a reasonable layout scheme from the valid layout schemes and outputs the reasonable layout scheme to the preset management terminal.
