Description

Technical Field

[0001] The present application relates to the technical field related to resource allocation optimization, and specifically to a resource allocation optimization method and system for a gas pipeline modification construction project. Background Art

[0002] Gas pipeline modification projects involve extensive and dispersed construction areas, with complex and diverse construction plans. Geographically, construction areas span the entire city, with varying topography, surrounding environments, and underground pipeline conditions. Multiple pre-configured construction plans are required to address the specific conditions in each construction area, each with varying requirements for the type, quantity, and duration of construction resources. Traditional methods of allocating construction resources present numerous challenges. For one thing, it's difficult to accurately estimate the resources required for different construction plans, leading to insufficient or excessive resource preparation. Furthermore, the status of non-consumable resources, such as construction equipment and temporary construction facilities, is often overlooked during resource allocation, making effective coordination difficult. This leads to resource conflicts, resulting in wasted resources and construction delays.

[0003] Therefore, in the current relevant technologies, there are technical problems such as lack of systematic allocation of construction resources and inaccurate resource demand prediction, which lead to difficulties in coordinated allocation of gas pipeline construction resources, low resource utilization efficiency and high construction costs. Summary of the Invention

[0015] The embodiment of the present application provides a method for optimizing resource allocation of a gas pipeline modification construction project, such as Figure 1 As shown, the method includes:

[0016] Step S100 : reading a plurality of preset construction areas and a plurality of preset construction plans of a gas pipeline modification construction project, as well as construction sequence constraints of the plurality of preset construction areas.

[0017] Preferably, the city's gas pipelines are widely distributed, and the entire modification construction project is divided into multiple smaller, relatively independent construction areas. For example, according to different blocks, communities or different sections of the pipeline, based on the planning documents of the gas pipeline modification construction project, and using GIS software, the geographic data layer related to the gas pipeline is loaded, and multiple preset construction areas are intuitively obtained through map visualization; for each preset construction area with different characteristics, there is a different construction process, that is, a preset construction plan, each construction plan is different in construction technology, construction equipment, construction personnel requirements, etc., and each construction area has a construction sequence requirement, that is, a construction sequence constraint, for example, the main pipeline for gas transmission must be modified first, and then the branch pipeline can be modified; the surrounding environment and social factors will also affect the construction sequence, such as some areas must give priority to ensuring their gas supply, and the construction sequence constraint avoids mutual interference between different construction areas and improves construction efficiency and safety.

[0018] Step S200 : performing construction resource demand forecasting based on the plurality of preset construction plans respectively, and generating a plurality of forecast construction resources.

[0019] Preferably, for each preset construction plan in the gas pipeline modification construction project, various types of construction resources required to complete the plan are predicted, that is, the demand for human resources, material resources and equipment resources during the construction process is estimated, so as to obtain the resource demand prediction results corresponding to each construction plan, that is, generate multiple predicted construction resources. Specifically, different construction plans adopt different construction processes and require different human resources. For example, the traditional excavation construction plan may require more pipeline installation workers, excavator drivers, earthwork workers, etc., while the construction plan using trenchless directional drilling requires more professional directional drilling operators, pipeline welding workers and related technical engineers; then according to the construction plan According to the design requirements, the amount of various materials must be accurately calculated. For example, a gas pipeline modification project needs to calculate the required number of gas pipelines, pipe fittings (such as elbows, tees, valves, etc.), sealing materials, anti-corrosion materials, etc. based on the length, diameter and connection method of the pipeline, and take into account the material loss rate to ensure sufficient material supply; each construction plan requires its own construction equipment. For example, excavation construction requires earthmoving construction equipment such as excavators, loaders, and cranes, as well as electric welders and flaw detection equipment for pipeline welding. Trenchless construction requires directional drilling rigs, pipe jacking machines and other equipment. The type of construction equipment is determined according to the construction process corresponding to each construction plan, and the number of equipment is calculated based on the construction task volume.

[0020] Furthermore, step S200 also includes step S210, determining multiple preset construction periods of the multiple preset construction areas; step S220, using the multiple preset construction periods as time constraints, performing resource forecasting for the multiple preset construction plans under different completion times, and generating multiple predicted resource sets; step S230, performing a balanced mapping of the idle rate and completion time of each resource based on the multiple predicted resource sets, and generating the multiple predicted construction resources.

[0021] Step S220 further includes that any predicted resource in the plurality of predicted resource sets includes at least personnel resources, material resources and equipment resources.

[0022] Preferably, in the gas pipeline modification construction project, different construction areas have different construction periods due to differences in construction conditions, construction scale, construction technology, etc. Specifically, the preset construction period corresponding to each preset construction area is estimated and determined based on the construction scale (the length of the gas pipeline that needs to be modified in the construction area, the number of pipeline nodes involved, etc.), construction conditions (geographical environment, traffic conditions, underground obstacles, etc.) and construction technology; then, with the preset construction period as the time limit condition, the required resources are predicted for different preset construction plans in each construction area according to different completion times. Specifically, based on the preset construction period, multiple possible completion time situations are considered, and the personnel resource requirements, i.e., the number of construction personnel, are calculated based on the completion time and the amount of construction tasks; the supply of material resources is adjusted based on the construction progress forecast to ensure that there is no shortage of materials during the construction process; the number and usage time of the required equipment are determined based on the completion time and the working efficiency of the equipment, i.e., the equipment resource requirements are predicted; and then multiple predicted resource sets are generated, each predicted resource at least including the construction personnel resources, construction material resources and construction equipment resources of the gas pipeline modification project.

[0023] Preferably, a balanced mapping of resource idle rates and completion times is performed based on multiple predicted resource sets. The resource idle rate refers to the proportion of time a resource is unused during the construction process. Specifically, for each resource in each predicted resource set, its idle rate at different completion times is calculated. For example, for a piece of construction equipment, if its actual usage time at a certain completion time is 20 days, and the preset construction period is 30 days, then its idle rate is (30-20) ÷ 30 = 33.3%. By calculating the resource idle rate, the resource utilization efficiency can be understood. The relationship between the resource idle rate and the completion time is then analyzed and balanced mapping is performed to minimize the resource idle rate and improve resource utilization efficiency while ensuring that the construction project can be completed on time. For example, if a construction plan can complete construction ahead of schedule with a shorter completion time, but the idle rate of personnel and equipment is too high, resulting in resource waste, then the construction schedule or resource allocation needs to be appropriately adjusted to achieve a better balance. By balanced mapping of resource idle rates and completion times, corresponding predicted construction resources are generated for each preset construction plan.

[0024] Furthermore, step S220 also includes step S221, digitally modeling the multiple preset construction plans to generate multiple digital construction models; step S222, executing construction simulation within the multiple preset construction cycles through the multiple digital construction models to generate multiple simulation results; step S223, forming the multiple predicted resource sets with the personnel resources, material resources and equipment resources corresponding to the multiple simulation results.

[0025] Preferably, each preset construction plan in the gas pipeline modification construction project is constructed into a virtual digital model using digital technology, which includes various key elements and information in the construction plan. Specifically, the topography of the construction area, the distribution of surrounding buildings, the layout of underground pipelines, etc. are integrated into the digital model using tools such as the geographic information system (GIS). Then, according to the construction steps and sequence in the preset construction plan, the model simulates the process from pipeline dismantling, laying to connection, etc. At the same time, the resource information such as personnel, materials, equipment, etc. required for construction is added to the digital model, including the type of work, number, skill level of the personnel, the type, specification, quantity of materials, the model and performance of the equipment, etc., thereby generating multiple digital construction models.

[0026] Preferably, the gas pipeline renovation construction process is simulated based on the digital construction model, and the simulation time range is the corresponding preset construction period. Through construction simulation, the various situations and results that may occur in the construction process under different preset construction periods are understood, and multiple simulation results are generated, including simulating the start time, end time and duration of each construction stage according to the preset construction period, and analyzing whether the construction progress can be completed as planned; simulating the use and deployment of personnel, materials, and equipment during the construction process, such as whether there will be shortages and idle personnel, whether the supply of materials meets construction needs, whether equipment will malfunction or be overused, etc.; at the same time, predicting the risks and problems that may be encountered during the construction process, such as the impact of underground obstacles, construction accidents, etc. on the construction progress and resources; finally, extracting the personnel resources, material resources, and equipment resources required for each construction plan from the simulation results, and forming a predicted resource set, which is helpful for the resource allocation and management of the gas pipeline construction project to ensure that the construction project can be successfully completed within the preset period while avoiding waste and shortage of resources.

[0027] Furthermore, step S230 also includes step S231, calculating the ratio of resource vacancy time to total construction execution time for any predicted resource in the multiple predicted resource sets to generate multiple resource idle rate sets; step S232, extracting the completion duration corresponding to any predicted resource based on the multiple simulation results to generate multiple completion time sets; step S233, extracting the first completion time set corresponding to the first preset construction area, and determining the first resource idle rate of the first predicted resource with the shortest completion time in the first completion time set; step S234, if the first resource idle rate is less than or equal to the preset idle rate threshold, taking the first predicted resource as the predicted construction resource of the first preset construction area, and adding it to the multiple predicted construction resources.

[0028] Preferably, among multiple predicted resource sets (including resource requirements such as personnel, materials, and equipment under different preset construction plans and preset construction cycles), for each predicted resource (i.e., each set of resource demand information in the set), the ratio of its resource vacancy time (i.e., the time during which the resource is not used during the entire construction process) to the total construction execution time (the time spent from the start to the end of the entire construction project) is calculated to obtain the resource idle rate of the resource, and multiple resource idle rates are calculated for all resources to form multiple resource idle rate sets. Then, the construction completion time corresponding to each predicted resource (i.e., the time spent from the start to the end of construction) is extracted from each simulation result, and multiple completion time sets are generated for different preset construction plans and preset construction cycles.

[0029] Preferably, one is randomly determined from all the preset construction areas as the first preset construction area, and the first completion time set corresponding to this preset construction area is extracted. Then, the predicted resource with the shortest completion time is determined in the first completion time set, and it is used as the first predicted resource and the corresponding resource idle rate is marked as the first resource idle rate. Assuming that the first completion time set corresponding to the first preset construction area is [20 days, 18 days, 22 days], the predicted resource corresponding to the shortest completion time of 18 days is the first predicted resource, and its corresponding resource idle rate (i.e., the first resource idle rate) is determined from the resource idle rate set. Based on the historical data of gas pipeline construction, a standard value of the resource idle rate is pre-set, that is, the preset idle rate threshold, and then the first resource idle rate is compared with the preset idle rate threshold. If the first resource idle rate is less than or equal to the preset idle rate threshold, it means that the first predicted resource has a short construction completion time and the resource idle rate is within an acceptable range, which is a relatively ideal resource allocation scheme. The first predicted resource is used as the predicted construction resource of the first preset construction area to guide the actual construction resource allocation of the first preset construction area, and is added to the set of multiple predicted construction resources to facilitate comprehensive consideration and optimal allocation of resources for the entire construction project.

[0030] Step S300: Connect to the gas pipeline construction platform and read the non-consumable resource status information.

[0031] Preferably, the gas pipeline construction platform is used to monitor and manage gas pipeline renovation and construction projects. It connects to the gas pipeline construction platform via a network connection, interface docking, and other means, and conducts data exchange to obtain non-consumable resource status information stored on the gas pipeline construction platform. This primarily includes personnel resource status information and equipment resource status information. Specifically, the platform obtains information related to personnel involved in gas pipeline construction, including but not limited to their work status (e.g., whether they are working, resting, on standby, etc.), their skill level, their current location, and their work time records. It also obtains information related to various types of equipment used in construction, such as their operating status (normal operation, faulty, under maintenance, idle, etc.), their frequency of use, their current location, and their remaining service life or maintenance cycle. By obtaining non-consumable resource status information, the platform provides a comprehensive understanding of the personnel and equipment involved in gas pipeline construction, enabling scientific resource scheduling and management, and improving construction efficiency.

[0032] Step S400 : Based on the construction sequence constraint, resource conflicts of non-consumable resources are identified for the plurality of predicted construction resources using the non-consumable resource status information, and a conflict resource mapping is constructed.

[0033] Preferably, resource conflicts of non-consumable resources are identified for multiple predicted construction resources, including personnel conflict identification based on construction sequence constraints and equipment conflict identification based on construction sequence constraints. Specifically, according to the construction sequence constraints, check whether there are conflicts in time and personnel requirements for different construction tasks. For example, according to the construction sequence, two tasks need to be carried out simultaneously at a certain moment, and both tasks require personnel with specific skills, and the number of such personnel available for deployment is limited, and the needs of both tasks cannot be met at the same time, thus generating a personnel resource conflict; according to the construction sequence, check whether there are conflicts in the allocation of equipment resources. For example, at a certain construction stage, according to the construction sequence, multiple tasks need to use the same construction equipment, and the equipment can only be used for one task at the same time, thus generating an equipment resource conflict. Through resource conflict identification, conflicting non-consumable resources (including construction personnel and construction equipment) are identified. Then, a mapping relationship is established between the conflicting non-consumable resources and the conflicting construction tasks, construction time and other information. This forms a conflict resource mapping, which clearly shows which non-consumable resources conflict at what time and in which construction tasks. This allows for an intuitive understanding of the resource conflict situation in gas pipeline construction, allowing for appropriate adjustments and optimization measures to be taken, such as adjusting the construction sequence, increasing resource input or rationally allocating resources, to resolve non-consumable resource conflicts and ensure the smooth progress of the renovation construction project.

[0034] Furthermore, step S400 also includes step S410, using the non-consumable resource status information to judge the non-consumable resource satisfaction status of a single construction area for the multiple predicted construction resources, generating a first separate conflict area and a first separate conflict resource, and constructing a first conflict mapping; step S420, based on the construction sequence constraint, determining a construction area combination whose construction sequence can be parallel; step S430, determining the predicted construction resource combination corresponding to the construction area combination; step S440, using the non-consumable resource status information to perform a conflict judgment on the predicted construction resource combination, and if a conflict exists, determining the conflicting resource; step S450, constructing a second conflict mapping with the conflicting resource and the corresponding construction area combination; step S460, constructing the conflict resource mapping with the first conflict mapping and the second conflict mapping.

[0035] Preferably, the status information of non-consumable resources (personnel and equipment) is used to analyze the predicted construction resources of each single construction area to determine whether the existing non-consumable resources in the construction area can meet the construction needs according to the arrangement of the predicted construction resources. That is, by checking the status information of non-consumable resources (current working status of personnel, operating status of equipment, etc.), it is determined whether the needs are met. If the non-consumable resources cannot meet the predicted construction resource needs of the construction area, the construction area is determined as the first separate conflict area, and the specific non-consumable resources that cause the conflict, that is, the first separate conflict resource, are identified. Then, a mapping relationship is established between the first separate conflict area and the corresponding first separate conflict resource to form a first conflict mapping, so as to view the resource conflict situation in a single construction area.

[0036] Preferably, based on the construction sequence constraint, a combination of construction areas that do not have mutual constraints on the construction sequence and can be constructed simultaneously is determined. For example, for pipeline laying work in different blocks, if there is no mutual influence between them (such as no sequence in pipeline connection, etc.) and the construction sequence constraint is satisfied, the construction areas of these blocks can be combined together as an area combination that can be constructed in parallel; then the predicted construction resources corresponding to each construction area combination are determined, and combined together to form a predicted construction resource combination. For example, a certain construction area combination consists of two construction areas. The predicted construction resources of the first construction area include a certain number of welders, pipeline materials and welding equipment, etc., and the predicted construction resources of the second construction area include personnel of other trades, pipelines of different specifications and corresponding transportation equipment, etc. The predicted construction resources of the two construction areas are integrated to form a predicted construction resource combination corresponding to the construction area combination.

[0037] Preferably, the non-consumable resource status information is used to analyze the predicted construction resource combination of each construction area combination to determine whether the non-consumable resources can meet the predicted construction resource needs in the area combination of parallel construction. If not, the specific non-consumable resources that cause the conflict are determined, and a mapping relationship is established between the determined conflicting resources and the corresponding construction area combination to form a second conflict mapping, which can clearly understand which non-consumable resource conflicts exist in which area combinations of parallel construction; finally, the first conflict mapping (reflecting the resource conflict situation in a single construction area) and the second conflict mapping (reflecting the resource conflict situation in the parallel construction area combination) are integrated to form a complete conflict resource mapping, which comprehensively displays all information related to non-consumable resource conflicts in the gas pipeline construction and renovation project, including conflicts in a single area and conflicts in parallel area combinations.

[0038] Furthermore, step S440 also includes step S441, reading the non-consumable resource type and required quantity in the predicted construction resource combination; step S442, judging whether the non-consumable resource status information fully meets the non-consumable resource type and required quantity; step S443, if not, determining that there is a conflict, and determining that the resource type and quantity are not met, and generating the conflicting resources.

[0039] Preferably, the types and required quantities of non-consumable resources in the predicted construction resource combination are read, that is, relevant information of non-consumable resources (i.e., technicians and construction equipment) is extracted from the predicted construction resource combination, including clarifying the types of non-consumable resources, such as the types of construction personnel (such as welders, electricians, pipe fitters, etc.), the types of construction equipment (such as excavators, welding equipment, cranes, etc.), and the required quantities corresponding to each type of non-consumable resources, such as how many welders, equipment operators, and excavators are needed; and then combining it with the non-consumable resource status information (i.e., the status of personnel and equipment used for actual construction, including the number of personnel, skill level, equipment, etc.). The actual non-consumable resource status is compared with the predicted construction resource combination (operating status, available quantity, etc.) to determine whether the actual non-consumable resource status can fully meet the requirements for the non-consumable resource type and quantity in the predicted construction resource combination; if the non-consumable resource status information cannot fully meet the non-consumable resource type and required quantity in the predicted construction resource combination, it is determined that there is a resource conflict, and further determination is made as to which non-consumable resource types and quantities do not meet the requirements, that is, to identify which technical personnel (such as insufficient number of personnel for a certain type of work or mismatched skills) and construction equipment (such as insufficient equipment or equipment failure that cannot be used) have problems, and ultimately the technical personnel and construction equipment that do not meet the requirements are identified as conflicting resources.

[0040] Step S500 : Based on the conflicting resource mapping, collaborative configuration of conflicting resources is performed under the constraints of a preset construction period of the corresponding construction area to generate a collaborative configuration result.

[0041] Preferably, according to the conflict resource mapping, the conflict resources are collaboratively configured under the preset construction period constraints of the corresponding construction area. When performing the collaborative configuration of conflict resources, it is necessary to ensure that all resource adjustments and configuration operations are carried out within the preset construction period. The construction task cannot be delayed or exceed the prescribed construction period due to the reconfiguration of resources. Specifically, according to the situation of the conflicting resources, the reasonable allocation of non-consumable resources between different construction areas is considered, such as allocating construction personnel or construction equipment in the surplus area to the shortage area; under the condition of satisfying the construction sequence constraints, the order of some construction tasks is fine-tuned, such as adjusting the construction sequence of two parallel construction areas with resource conflicts so that the construction needs are met under the existing resource conditions; considering adding temporary resources to resolve resource conflicts, such as adding additional construction equipment or technicians to supplement, so as to ensure the smooth progress of the gas pipeline construction project. The collaborative configuration results are generated by the collaborative configuration of conflicting resources, which clearly state which specific configuration measures are taken for each conflict area, such as which personnel and equipment are deployed, which construction sequence is adjusted, which temporary resources are added, etc., to ensure that the entire construction project can proceed smoothly and the tasks of each construction area are completed on time.

[0042] Furthermore, step S500 also includes step S510, determining the conflicting individual construction areas and construction area combinations based on the conflicting resource mapping; step S520, optimizing the individual construction areas according to the non-consumable resource status information to generate individual optimization results; step S530, configuring the construction execution time sequence of the construction area combination to determine the call execution relationship; step S540, determining the collaborative configuration result based on the individual optimization results and the call execution relationship.

[0043] Preferably, by analyzing the conflict resource mapping, the separate construction areas with resource conflicts are clearly identified, such as the gas pipeline modification construction area in a certain community may have conflicts due to insufficient number of welders; at the same time, the combination of construction areas with conflicts (that is, multiple area combinations that can be constructed in parallel) is determined, for example, when several adjacent blocks are under construction at the same time, there may be competition for a certain type of excavator; then, the separate construction areas with conflicts are optimized based on the non-consumable resource status information (such as personnel skill level, work status, equipment operation status, available quantity, etc.), such as reallocating personnel, deploying temporarily idle technicians in other areas to the conflict area, or repairing construction equipment, etc., to meet the construction needs of the area, and then obtaining a resource optimization plan for the construction area, that is, a separate optimization result.

[0044] Preferably, the construction execution time of conflicting construction area combinations is arranged in sequence, that is, the construction start time of each area is determined according to the construction difficulty of each area, the impact on the overall construction progress, the availability of resources, etc., and then the call execution relationship between each construction area is determined. For example, there is a resource conflict between construction area combinations A and B. After analysis, the construction difficulty of area A is relatively low and the impact on the overall progress is small, so it is determined to carry out the construction of area B first, and then carry out the construction of area A after the resources are released; finally, the individual optimization results and the call execution relationship are integrated to obtain a comprehensive collaborative configuration result, which includes the resource allocation and construction time arrangement of all conflicting areas (including individual construction areas and construction area combinations), which can effectively solve the resource conflict problem and ensure that the entire gas pipeline renovation construction project proceeds smoothly within the preset construction period.

[0045] Step S600 : performing optimal configuration of non-conflicting resources based on the collaborative configuration result to generate a resource optimization configuration result.

[0046] Preferably, non-conflicting resources are optimally configured based on the collaborative configuration results. Specifically, after adjusting conflicting resources (such as deploying or replacing construction equipment), check whether existing personnel have the ability to operate the new equipment and whether the number matches the equipment. In addition, a comprehensive assessment of other non-conflicting resources is required. For example, whether the supply of construction materials will be affected by resource adjustments and whether the transportation of materials needs to be adjusted; whether safety equipment matches the new construction plan and whether it needs to be increased or decreased; and then optimize the configuration of non-conflicting resources, which may include the redistribution of personnel, the reallocation of materials, and the rearrangement of safety protection equipment, so as to ensure that all resources can cooperate efficiently and in a coordinated manner to avoid waste of resources or low construction efficiency; and finally form a resource optimization configuration result, which explains the specific configuration for each non-conflicting resource, thereby ensuring that the entire gas pipeline construction process proceeds smoothly under the premise of rational resource utilization.

[0047] Furthermore, step S600 also includes step S610, constructing multiple resource collaborative relationships based on the multiple predicted construction resources and the multiple preset construction plans; step S620, after optimizing the configuration of non-conflicting resources with the collaborative configuration results, optimizing the configuration of corresponding collaborative resources with the multiple resource collaborative relationships to generate the resource optimization configuration results.

[0048] Preferably, through in-depth analysis of multiple predicted construction resources and preset construction plans, the coordination relationship between different types of resources, that is, the resource synergy relationship, is found, which may include but is not limited to the coordination relationship between personnel, equipment and materials, and the coordination relationship between construction equipment. For example, welders (personnel resources) need to cooperate with welding equipment (equipment resources) and welding materials (material resources). Suitable welders can skillfully operate specific welding equipment and use welding materials that meet the requirements to ensure welding quality and construction progress; when excavators are digging pipeline trenches, they need to cooperate with loaders to transport the excavated earth in time.

[0049] Preferably, non-conflicting resources are optimized based on the collaborative configuration results, mainly considering the chain reaction caused by the adjustment of conflicting resources on non-conflicting resources. For example, when the equipment in the conflicting resources is adjusted, the related non-conflicting resources such as personnel configuration and material requirements also need to be adjusted accordingly to ensure the smooth progress of the entire construction process. After completing the initial optimization of non-conflicting resources, the relevant collaborative resources are further optimized based on multiple resource collaborative relationships. For example, if the collaborative relationship between welders and welding equipment in a certain construction area is not ideal, it may be that the welders' skill level does not match the advanced level of the equipment, resulting in the equipment's performance not being fully utilized.
