Description

Technical Field

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

[0002] The construction areas of gas pipeline modification construction projects are extensive and scattered, and the construction plans are complex and diverse. The construction areas are geographically distributed in every corner of the city, and the topographies, surrounding environments, and underground pipeline conditions in different areas are different. At the same time, multiple preset construction plans need to be formulated to deal with the situations in different construction areas, and each plan has different requirements for the types, quantities, and usage times of construction resources. There are many problems with traditional construction resource allocation methods. On the one hand, it is difficult to accurately estimate the construction resources required for different construction plans, resulting in insufficient or excessive resource preparation. On the other hand, for non-consumable resources, such as construction equipment and temporarily built construction facilities, their states are often ignored during the resource allocation process, making it difficult to effectively coordinate, which in turn leads to resource conflicts, resulting in resource waste and construction schedule delays.

[0003] Therefore, in the current related technologies, there are technical problems such as lack of systematicness in construction resource allocation, inaccurate prediction of resource requirements, difficult collaborative allocation of gas pipeline construction resources, low resource utilization efficiency, and high construction costs.

The terms used herein are only for the purpose of describing the embodiments of the present application.

[0015] An embodiment of the present application provides a method for optimizing the resource allocation of a gas pipeline modification construction project, as Figure 1 shown. The method includes: Step S100, reading multiple preset construction areas and multiple preset construction plans of the gas pipeline modification construction project, and the construction sequence constraints of the multiple preset construction areas.

[0016] Preferably, the gas pipelines in the city are widely distributed. The entire renovation construction project is divided into multiple smaller and relatively independent construction areas. For example, it is divided according to different blocks, communities, or different segments of the pipelines. According to the planning document of the gas pipeline renovation construction project and using GIS software, the geographical data layers related to the gas pipelines are loaded, and multiple preset construction areas are visually obtained through map visualization. For each preset construction area with different characteristics, there are different construction processes, that is, preset construction plans. Each construction plan is different in terms of construction technology, construction equipment, and construction personnel requirements. Moreover, there are requirements for the construction sequence among the construction areas, that is, construction sequence constraints. For example, the main gas transmission pipelines need to be renovated first, and then the branch pipeline renovation construction can be carried out. The surrounding environment and social factors will also affect the construction sequence. For example, the gas supply in certain areas needs to be ensured first. The construction sequence constraints avoid interference between different construction areas, improving construction efficiency and safety.

[0017] Step S200, based on the multiple preset construction plans, respectively conduct construction resource demand prediction to generate multiple predicted construction resources.

[0018] Preferably, for each preset construction plan in the gas pipeline renovation construction project, predict various construction resources required to complete the plan, that is, estimate the demand for personnel resources, material resources, and equipment resources during the construction process, 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 technologies and require different personnel resources. For example, a traditional excavation construction plan may require more pipeline installers, excavator drivers, earthwork workers, etc., while a trenchless directional drilling construction plan requires more professional directional drilling operators, pipeline welders, and relevant technical engineers. Then, according to the design requirements of the construction plan, accurately calculate the usage of various materials. For example, in a gas pipeline renovation project, according to the length, diameter, and connection method of the pipeline, calculate the quantity of gas pipelines, pipe fittings (such as elbows, tees, valves, etc.), sealing materials, anti-corrosion materials, etc. required, and consider the material loss rate to ensure sufficient material supply. Each construction plan requires its own construction equipment. For example, excavation construction requires earthwork construction equipment such as excavators, loaders, and cranes, as well as welding machines and flaw detection equipment for pipeline welding. Trenchless construction requires equipment such as directional drilling rigs and pipe jacking machines. Determine the type of construction equipment according to the construction technology corresponding to each construction plan, and calculate the equipment quantity according to the construction workload.

[0019] Further, step S200 further includes step S210 of determining the multiple preset construction periods of the multiple preset construction areas; step S220 of predicting resources at different completion times for the multiple preset construction plans respectively with the multiple preset construction periods as time constraints to generate multiple predicted resource sets; and step S230 of performing balanced mapping of the various resource idle rates and completion times based on the multiple predicted resource sets to generate the multiple predicted construction resources.

[0020] Step S220 further includes that any predicted resource in the multiple predicted resource sets at least includes personnel resources, material resources, and equipment resources.

[0021] 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, according to the construction scale (the length of the gas pipeline to be modified within the construction area, the number of pipeline nodes involved, etc.), construction conditions (geographical environment, traffic conditions, underground obstacles, etc.), and construction technology, estimate and determine the preset construction period corresponding to each preset construction area; then, with the preset construction period as the time limit condition, predict the required resources for different preset construction plans in each construction area according to different completion times. Specifically, according to the preset construction period, consider various possible completion time situations, calculate the personnel resource requirements, that is, the number of construction personnel, based on the completion time and the construction task volume; predict and adjust the material resource supply according to the construction progress to ensure that there is no shortage of materials during the construction process; determine the quantity and usage time of the required equipment, that is, predict the equipment resource requirements, based on the completion time and the working efficiency of the equipment; and then generate multiple predicted resource sets, and each predicted resource at least includes the construction personnel resources, construction material resources, and construction equipment resources of the gas pipeline modification project.

[0022] Preferably, perform balanced mapping of various resource idle rates and completion times based on multiple prediction resource sets. The resource idle rate refers to the proportion of time when the resource is not utilized during the construction process. Specifically, for various resources in each prediction resource set, calculate their idle rates at different completion times. For example, for a construction equipment, if its actual usage time is 20 days at a certain completion time and the preset construction period is 30 days, then its idle rate is (30 - 20) ÷ 30 = 33.3%. By calculating the resource idle rate, understand the utilization efficiency of the resource; then analyze the relationship between the resource idle rate and the completion time and perform balanced mapping to minimize the idle rate of the resource and improve the utilization efficiency of the resource on the premise that the construction project can be completed on time. For example, if a certain construction plan can complete the construction ahead of schedule at a shorter completion time, but it will result in too high idle rates of personnel and equipment, causing resource waste, then it is necessary to appropriately adjust the construction progress or resource allocation to achieve a better balance. Through the balanced mapping of the resource idle rate and the completion time, corresponding predicted construction resources are generated for each preset construction plan.

[0023] Furthermore, step S220 further includes step S221, performing digital modeling on the multiple preset construction plans to generate multiple digital construction models; step S222, performing construction simulation within the multiple preset construction periods through the multiple digital construction models to generate multiple simulation results; step S223, forming the multiple prediction resource sets with the personnel resources, material resources, and equipment resources corresponding to the multiple simulation results.

[0024] Preferably, each preset construction plan in the gas pipeline conversion construction project is constructed into a virtual digital model by using digital technology, which includes various key elements and information in the construction plan. Specifically, by using tools such as Geographic Information System (GIS), integrate the topography and geomorphology of the construction area, the distribution of surrounding buildings, the layout of underground pipelines, etc. into the digital model, and then simulate the pipeline demolition, laying, connection, etc. in the model according to the construction steps and sequences in the preset construction plan. At the same time, add resource information such as personnel, materials, and equipment required for construction to the digital model, including the types of work, quantity, and skill levels of personnel, the types, specifications, and quantities of materials, and the models and performances of equipment, so as to generate multiple digital construction models.

[0025] Preferably, based on the digital construction model, simulate the construction process of the gas pipeline renovation. The simulation time range is the corresponding preset construction period. Through construction simulation, understand various situations and results that may occur during the construction process under different preset construction periods, and generate multiple simulation results, 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 usage and allocation of personnel, materials, and equipment during the construction process, such as whether there will be shortages and idleness of personnel, whether the supply of materials meets the construction requirements, whether equipment fails or is overused, etc.; at the same time, predict 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, extract the personnel resources, material resources, and equipment resources required for each construction plan from the simulation results and form a predicted resource set, which helps with 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.

[0026] Further, step S230 further includes step S231, calculating the ratio of the resource vacancy time to the 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, use the first predicted resource as the predicted construction resource for the first preset construction area and add it to the multiple predicted construction resources.

[0027] Preferably, in the multiple predicted resource sets (including resource requirements such as personnel, materials, and equipment under different preset construction plans and preset construction periods), for each predicted resource (i.e., each set of resource requirement information in the set), calculate the ratio of its resource vacancy time (i.e., the time when the resource is not used during the entire construction process) to the total construction execution time (the time taken from the start to the end of the entire construction project) to obtain the resource idle rate of the resource. Calculate for all resources to obtain multiple resource idle rates and form multiple resource idle rate sets. Then, extract the construction completion duration corresponding to each predicted resource (i.e., the time taken from the start to the end of the construction) from each simulation result, and generate multiple completion time sets for different preset construction plans and preset construction periods.

[0028] Preferably, randomly determine one of all the preset construction areas as the first preset construction area, extract the first completion time set corresponding to this preset construction area, then determine the prediction resource with the shortest completion time in the first completion time set, take it as the first prediction resource and mark the corresponding resource idle rate as the first resource idle rate. Assume that the first completion time set corresponding to the first preset construction area is [20 days, 18 days, 22 days], and the prediction resource corresponding to the shortest completion time of 18 days is the first prediction resource, and determine its corresponding resource idle rate (i.e., the first resource idle rate) from the resource idle rate set. According to the historical data of gas pipeline construction, preset a standard value of the resource idle rate, that is, the preset idle rate threshold, and then compare the first resource idle rate 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 while the first prediction resource has a shorter construction completion time, the resource idle rate is also within an acceptable range, which is an ideal resource allocation plan. Then take the first prediction resource as the predicted construction resource for the first preset construction area, use it to guide the actual construction resource allocation of the first preset construction area, and add it to the set of multiple predicted construction resources to facilitate the comprehensive consideration and optimized allocation of the resources for the entire construction project.

[0029] Step S300, connect to the gas pipeline construction platform and read the non-consumable resource status information.

[0030] Preferably, the gas pipeline construction platform is used to monitor and manage the gas pipeline renovation construction project. Connect to the gas pipeline construction platform through network connection, interface docking, etc., and perform data interaction and communication to obtain the non-consumable resource status information stored in the gas pipeline construction platform, mainly including personnel resource status information and equipment resource status information. Specifically, obtain the relevant situations of the personnel participating in the gas pipeline construction, including but not limited to the working status of the personnel (such as whether they are working, resting, on standby, etc.), the skill level of the personnel, the current distribution location of the personnel, the working time record of the personnel, etc.; obtain the relevant conditions of various equipment used in the construction, such as the operating status of the equipment (normal operation, failure, maintenance, idle, etc.), the usage frequency of the equipment, the current location of the equipment, the remaining service life or maintenance cycle of the equipment, etc. By obtaining the non-consumable resource status information, comprehensively understand the personnel and equipment conditions of the gas pipeline construction, so as to conduct scientific resource scheduling and management and improve the construction efficiency.

[0031] Step S400, based on the construction sequence constraint, identify the resource conflicts of non-consumable resources for the multiple predicted construction resources with the non-consumable resource status information, and construct a conflict resource mapping.

[0032] Preferably, resource conflict identification for multiple predicted construction resources includes 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 cannot meet the needs of both tasks at the same time, resulting in a personnel resource conflict; according to the construction sequence, check whether there are conflicts in the allocation of equipment resources. For example, in 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, resulting in an equipment resource conflict. Identify the non-consumable resources (including construction personnel and construction equipment) with conflicts through resource conflict identification, and then establish a mapping relationship between the non-consumable resources with conflicts and information such as the construction tasks and construction times that cause the conflicts, that is, form a conflict resource mapping, clearly showing at what time and in which construction tasks which non-consumable resources have conflicts, so as to intuitively understand the resource conflict situation of gas pipeline construction, and then take corresponding measures for adjustment and optimization, such as adjusting the construction sequence, increasing resource investment or reasonably allocating resources, etc., to solve the problem of non-consumable resource conflicts and ensure the smooth progress of the renovation construction project.

[0033] Further, step S400 further includes step S410, judging the non-consumable resource satisfaction status of a single construction area for the multiple predicted construction resources with the non-consumable resource status information, generating a first separate conflict area and a first separate conflict resource, and constructing a first conflict mapping; step S420, determining a combination of construction areas where the construction sequence can be parallel based on the construction sequence constraints; step S430, determining the corresponding combination of predicted construction resources for the combination of construction areas; step S440, judging the conflicts of the combination of predicted construction resources with the non-consumable resource status information, and if there are conflicts, determining the conflict resources; step S450, constructing a second conflict mapping with the conflict resources and the corresponding combination of construction areas; step S460, constructing the conflict resource mapping with the first conflict mapping and the second conflict mapping.

[0034] Preferably, using the status information of non-consumable resources (personnel and equipment), analyze the predicted construction resources for each individual construction area, and determine whether the existing non-consumable resources can meet the construction requirements according to the arrangement of the predicted construction resources in this construction area. That is, by checking the status information of non-consumable resources (the working status of current personnel, the operating status of equipment, etc.), determine whether the requirements are met. If the non-consumable resources cannot meet the predicted construction resource requirements of the construction area, then determine this construction area as the first single conflict area, and clarify the specific non-consumable resources that cause the conflict, that is, the first single conflict resources. Then establish a mapping relationship between the first single conflict area and the corresponding first single conflict resources to form the first conflict mapping, so as to view the resource conflict situation within a single construction area.

[0035] Preferably, according to the construction sequence constraint, determine the combination of construction areas that do not restrict each other in the construction sequence and can be constructed simultaneously. For example, for the pipeline laying work in different blocks, if there is no mutual influence between them (such as no sequence requirements for pipeline connection, etc.) and they meet the construction sequence constraint, then these construction areas in the blocks can be combined together as a combination of areas that can be constructed in parallel. Then determine the predicted construction resources corresponding to each construction area combination and combine them 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, 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. Integrate the predicted construction resources of these two construction areas to form the predicted construction resource combination corresponding to this construction area combination.

[0036] Preferably, using the status information of non-consumable resources, analyze the predicted construction resource combination for each construction area combination, and determine whether the non-consumable resources can meet the requirements of the predicted construction resources in the parallel construction area combination. If not, determine the specific non-consumable resources that cause the conflict, and establish a mapping relationship between the determined conflict resources and the corresponding construction area combination to form the second conflict mapping, so as to clearly understand which non-consumable resource conflicts exist in which parallel construction area combinations. Finally, integrate the first conflict mapping (reflecting the resource conflict situation within a single construction area) and the second conflict mapping (reflecting the resource conflict situation within the parallel construction area combination) to form a complete conflict resource mapping, comprehensively displaying all information related to non-consumable resource conflicts in the gas pipeline construction and renovation project, including conflicts in single areas and conflicts in parallel area combinations.

[0037] Further, step S440 further includes step S441 of reading the non-consumable resource types and required quantities in the predicted construction resource combination; step S442 of determining whether the non-consumable resource status information completely meets the non-consumable resource types and required quantities; step S443 of, if not, determining that there is a conflict, determining the resource types and quantities that are not met, and generating the conflicting resources.

[0038] Preferably, reading the non-consumable resource types and required quantities in the predicted construction resource combination means extracting the relevant information of non-consumable resources (i.e., technical personnel and construction equipment) from the predicted construction resource combination, including clarifying the types of non-consumable resources, such as the types of construction workers (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 non-consumable resource type, such as how many welders are needed, how many equipment operators are required, and how many excavators are needed; then comparing it with the non-consumable resource status information (i.e., the status of the personnel and equipment used in actual construction, including the number of personnel, skill levels, operating status of equipment, available quantity, etc.) to determine whether the actual non-consumable resource status can fully meet the requirements of the non-consumable resource types and quantities in the predicted construction resource combination; if the non-consumable resource status information cannot fully meet the non-consumable resource types and required quantities in the predicted construction resource combination, it is determined that there is a resource conflict, and further determine which non-consumable resource types and quantities do not meet the requirements, that is, clarify which technical personnel (such as the insufficient number of personnel of a certain type or the skill mismatch) and construction equipment (such as the insufficient number of equipment or the equipment failure and unable to be used) have problems, and finally determine the technical personnel and construction equipment that do not meet the requirements as the conflicting resources.

[0039] Step S500, based on the conflicting resource mapping, perform collaborative allocation of the conflicting resources under the preset construction period constraint of the corresponding construction area, and generate a collaborative allocation result.

[0040] Preferably, according to the conflict resource mapping, the collaborative configuration of conflict resources is carried out under the preset construction period constraint of the corresponding construction area. When carrying out the collaborative configuration of conflict resources, it is necessary to ensure that all resource adjustment and configuration operations are carried out within the preset construction period, and the construction tasks cannot be delayed due to the reconfiguration of resources, exceeding the specified construction period. Specifically, according to the situation of conflict resources, consider reasonably allocating non-consumable resources between different construction areas. For example, allocate construction personnel or construction equipment in the surplus area to the shortage area; under the condition of meeting the construction sequence constraint, fine-tune the order of some construction tasks. For example, for two parallel construction area combinations with resource conflicts, adjust their construction sequence so as to meet the construction requirements under the existing resource conditions; consider adding temporary resources to solve resource conflicts. For example, add additional construction equipment or technical personnel for supplementation to ensure the smooth progress of the gas pipeline construction project. Generate a collaborative configuration result through the collaborative configuration of conflict resources, and clearly explain for each conflict area what specific configuration measures have been taken, such as which personnel and equipment have been allocated, which construction sequences have been adjusted, and which temporary resources have been added, etc., to ensure the smooth progress of the entire construction project and the completion of tasks in each construction area on time.

[0041] Further, step S500 further includes step S510, based on the conflict resource mapping, determining the individual construction areas and combinations of construction areas where conflicts exist; step S520, optimizing the individual construction areas according to the non-consumable resource status information to generate an individual optimization result; step S530, performing a call configuration on the construction area combinations in the order of construction execution time to determine the call execution relationship; step S540, determining the collaborative configuration result based on the individual optimization result and the call execution relationship.

[0042] Preferably, by analyzing the conflict resource mapping, clarify the individual construction areas with resource conflicts. For example, the gas pipeline renovation construction area in a certain community may have conflicts due to insufficient welders; at the same time, determine the combinations of construction areas with conflicts (that is, multiple areas that can be constructed in parallel). For example, when several adjacent blocks are under construction at the same time, there may be a scramble for a certain type of excavator; then, for the individual construction areas with conflicts, optimize according to the non-consumable resource status information (such as the skill level, working status of personnel, the operation status and available quantity of equipment, etc.). For example, reallocate personnel, transfer the technical personnel temporarily idle in other areas to this conflict area, or repair the construction equipment, etc., to meet the construction requirements of this area, and then obtain a resource optimization plan for this construction area, that is, an individual optimization result.

[0043] Preferably, for the construction area combinations with conflicts, arrange the construction execution times in sequence. That is, according to the construction difficulty of each area, the impact on the overall construction progress, the availability of resources, etc., determine the sequence of the start times of construction in each area, and then determine the call execution relationship between each construction area. 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 its impact on the overall progress is small. Therefore, 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, integrate the individual optimization results and the call execution relationship to obtain a comprehensive collaborative configuration result, including the resource configuration and construction time arrangement of all areas with conflicts (including individual construction areas and construction area combinations), which can effectively solve the resource conflict problem and ensure the smooth progress of the entire gas pipeline renovation construction project within the preset construction period.

[0044] Step S600: Optimize the allocation of non-conflicting resources according to the collaborative configuration result to generate a resource optimization allocation result.

[0045] Preferably, optimize the allocation of non-conflicting resources according to the collaborative configuration result. Specifically, after adjusting the conflicting resources (such as deploying or replacing construction equipment), check whether the existing personnel have the ability to operate the new equipment and whether the quantity matches the equipment. In addition, it is also necessary to comprehensively evaluate other non-conflicting resources. For example, whether the supply of construction materials will be affected by the resource adjustment and whether the material transportation needs to be adjusted; whether the safety equipment matches the new construction plan and whether it needs to be increased or decreased; and then optimize the allocation of non-conflicting resources, which may include reassigning personnel, redistributing materials, and rearranging safety protection equipment, etc., to ensure that all resources can cooperate efficiently and coordinately and avoid resource waste or low construction efficiency. Finally, form a resource optimization allocation result, indicating the specific allocation for each non-conflicting resource, so as to ensure the smooth progress of the entire gas pipeline construction process on the premise of reasonable resource utilization.

[0046] Furthermore, step S600 further includes step S610: Based on the multiple predicted construction resources and the multiple preset construction plans, construct multiple resource collaboration relationships; step S620: After optimizing the allocation of non-conflicting resources according to the collaborative configuration result, optimize the allocation of corresponding collaborative resources according to the multiple resource collaboration relationships to generate the resource optimization allocation result.

[0047] Preferably, through in-depth analysis of multiple predicted construction resources and preset construction plans, the cooperation relationships between different types of resources, i.e., resource synergy relationships, are identified, which may include but are not limited to the cooperation relationships between personnel, equipment, and materials, and the cooperation relationships between construction equipment. For example, a welder (personnel resource) needs to cooperate with welding equipment (equipment resource) and welding materials (material resource). Only a suitable welder who can proficiently operate specific welding equipment and use compliant welding materials can ensure welding quality and construction progress. When an excavator is used for pipeline trench excavation, it needs to cooperate with a loader to promptly transport the excavated soil away.

[0048] Preferably, based on the collaborative configuration results, non-conflicting resources are optimized. The chain reaction of the adjustment of conflicting resources on non-conflicting resources is mainly considered. For example, when the equipment in the conflicting resources is adjusted, relevant 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 the preliminary optimization of non-conflicting resources is completed, based on multiple resource synergy relationships, more in-depth optimization of relevant collaborative resources is carried out. For example, if the synergy relationship between a welder and welding equipment in a certain construction area is not ideal, it may be that the skill level of the welder does not match the advanced degree of the equipment, resulting in the underutilization of the equipment's performance. Then, according to the resource synergy relationship, the welder is provided with skill training or a suitable welding equipment is replaced to optimize the collaborative resource configuration. By optimizing all resource synergy relationships, a resource optimization configuration result is generated, which covers the optimization of all resources in the construction project, including conflicting resources and non-conflicting resources, as well as the synergy relationships between different types of resources, making the cooperation between various resources closer and more efficient, thereby ensuring the rational utilization of resources and the smooth completion of construction tasks during the construction process.
