[0001] The present application relates to the field of visual management of offshore land construction, in particular to a visual control method and Kanban system for offshore jacket construction project work package. BACKGROUND
[0002] In the process of offshore land construction, welding operation is needed for the jacket, and in this process, the actual construction progress and the production progress of the coiled pipe need to be continuously monitored, and the consumption of materials is matched with the production to achieve the purpose of supply and demand balance.
[0003] Reviewing the past work mode, project production personnel have to frequently query and process data to project interface personnel, and then inform the relevant information to the on-site production management personnel, and in this information transmission process, the characteristics of transmission are presented, which not only leads to extremely low work efficiency, but also greatly reduces the timeliness of communication and transmission. At the same time, in the whole project process, there are often situations where production capacity does not match consumption, when production capacity greatly exceeds consumption, it will cause great pressure on storage, and when production capacity greatly lags behind consumption, it will affect the construction progress of the whole jacket construction project, causing delay in the construction period, and in the specific construction environment, there will be a situation where personnel are idle due to material shortage, which leads to an increase in the overall construction cost, and in view of the above, in order to effectively solve the above series of problems, a visual control method and Kanban system for offshore jacket construction project work package are provided. SUMMARY
[0004] In view of the deficiencies of the prior art, the present application provides a visual control method and Kanban system for offshore jacket construction project work package, which solves the problem that in the existing offshore jacket construction process, production and construction information are not intuitive and transparent, resulting in mismatch between production capacity and consumption, increased storage pressure, delayed construction period and increased construction cost.
[0005] To achieve the above purpose, the present application is realized by the following technical scheme: a visual control method for offshore jacket construction project work package, comprising: S1, importing construction progress data, material inventory data and material production progress data; S2, normalizing the imported data to obtain the current construction progress, material inventory growth rate and material production speed; S3, designing three interrelated data models by designing a unified model for construction progress, material inventory growth rate and material production progress; In the construction progress model, by comprehensively balancing personnel factors, building material matching factors and environmental factors, the construction progress is in the error interval, and the construction progress is ensured to be within a reasonable range; In the inventory model, by reasonably controlling , so that , wherein indicates the maximum storage capacity of the warehouse, to avoid the occurrence of warehouse explosion; In the material production progress model, by reasonably controlling the production capacity, , so as to ensure the supply of materials, while taking into account the storage capacity.

At this time, we can analyze it in combination with the construction progress model. If the actual progress is less than or equal to the standard progress, we can increase the construction speed. If the actual progress is greater than the standard progress, we can reduce the production speed. If not, it means that the inventory is in the consumption stage, at this time, combined with the construction progress model for analysis, if the actual progress ≥ standard progress × (1 + α), reduce the construction speed, If the actual progress ≤ standard progress × (1-α), the material production speed is improved, and finally the construction progress adjustment is realized, and the construction progress adjustment will affect the change of material inventory, realizing the cycle control.
[0014] Preferably, when controlling the inventory, because the construction progress and the consumption of consumables are nonlinearly proportional, the consumption speed and the demand of materials are different in different construction periods, therefore, when dividing the construction progress, the progress needs to be divided according to different construction stages, and then the high-consumable stage and the low-consumable stage can be roughly classified, and the corresponding material consumption and construction progress relationship function is designed, which can be represented as:
[0015] Among them The total material demand in unit time t period is represented; The proportional coefficient obtained by normalizing the relationship function between construction progress and material consumption speed.

DETAILED DESCRIPTION
[0025] In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0026] The present application provides a kind of marine guide pipe support construction project work package visual control method and board system, solve the existing marine guide pipe support construction process, there is production and construction information not intuitive transparent, thereby leading to capacity and consumption mismatch, make the problem of warehouse pressure increase, construction cycle delay and construction cost increase.
[0027] In order to better understand the above technical solutions, the above technical solutions will be described in detail in the following in conjunction with the drawings in the specification and specific embodiments.
[0028] Embodiment one, the present application discloses a kind of marine guide pipe support construction project work package visual control method, according to the drawings Figures 1-5 As shown in the figure, the following steps are included: S1, import construction progress data, material inventory data and material production progress data; S2, the imported data is normalized, so that current construction progress, material inventory growth rate and material production speed can be obtained; S3, by designing an overall planning model, the construction progress, material inventory growth rate and material production progress are designed into three interrelated data models; In the construction progress model, by comprehensively balancing personnel factors, building material matching factors and environmental factors, the construction progress is in the error interval, and the construction progress is ensured to be within a reasonable range; In the inventory model, by reasonably controlling , so that , wherein indicates the maximum storage capacity of the warehouse, to avoid the situation of warehouse explosion; In the material production progress model, by reasonably controlling the production capacity, , so as to ensure the material supply, while taking into account the storage capacity.
[0029] The construction progress formula is:
[0030] Wherein D represents personnel factors, R represents building material matching factors, and G represents environmental factors; ; indicates the error coefficient, ; The material inventory growth rate formula is: ; Wherein represents the material increment per unit time, represents the material consumption per unit time, represents the current inventory; The material production progress formula is: ; Wherein represents the current total production of materials, represents the total demand for materials throughout the construction period; The error interval is represented as: .
[0031] By reasonably controlling the production capacity, on the one hand, it ensures that each process in the production scheduling stage is stable and orderly, and on the other hand, it makes the entire production process more orderly, on the other hand, it ensures the material supply, avoids the situation that the production capacity cannot meet the consumption demand in the rapid material consumption stage, so as to achieve the purpose of reasonable production scheduling; By setting the overall planning model, the correlation data model of construction progress, material inventory and material production progress is developed in the overall planning model. In the construction progress model, by comprehensively balancing personnel factors, building material matching factors and environmental factors, the construction progress is within a reasonable range, and by reasonably controlling the inventory growth rate, the situation of warehouse explosion is avoided, and by reasonably controlling the production capacity, the material supply is ensured, so as to balance the production, storage and consumption of materials, ensure that the jacket construction can be completed as expected, and balance the supply and storage of materials, so as to reduce the overall cost.
[0032] At the same time in the process of inventory control, the consumption speed and demand of materials are different in different construction periods, so when dividing the construction progress, the progress needs to be divided according to different construction stages, and then it can be roughly classified into high material consumption stage and low material consumption stage, and the corresponding material consumption and construction progress relationship function is designed in the corresponding stage, so that the warehouse can effectively guarantee the material supply and avoid warehouse explosion in response to different construction stages.
[0033] In the overall planning model, the construction progress control logic is embedded to intelligently control the construction progress model, the inventory model and the material production progress model, and the specific steps are as follows: S1, obtaining current construction progress data, material inventory data and material production progress data; S2, comparing the actual construction progress with the expected construction progress; S3, adjusting the construction speed according to the comparison result; S4, adjusting the production speed according to the material inventory; S5, ensuring that the engineering progress meets the time limit requirement.
[0034] The execution strategy of S3 is as follows: Step one, construction progress data acquisition, which includes which stage the current construction is in, the personnel ratio of the current construction, the on-site situation of the related equipment, the climate condition in the next construction period, and the material supply condition in the current construction stage; Step two, construction progress monitoring, comparing the actual progress with the threshold value, quantifying through the pre-designed construction progress plan, and introducing the corresponding error coefficient α, which changes in different stages of construction, for example, in the preparation stage, the error coefficient can be set to be larger, because the construction in this stage is less affected by objective factors such as materials and environment, and the progress can be quickly improved by increasing the shift; In the pouring stage, the error coefficient needs to be set smaller, because in this stage, the poured material needs to be standardized after pouring, that is, the objective factors have a greater impact, and the progress cannot be improved by simple means. Step three, analyzing and judging the current progress; Is the actual progress ∈ [standard progress * (1+α), standard progress * (1-α)]? If yes, it means that the current progress range is within the threshold value, and the current progress is maintained; If not, it means that the current progress is out of the threshold value, and then the differential judgment operation is performed; Is the actual progress ≤ standard progress * (1-α)? If yes, it means that the current progress falls behind the minimum duration progress category, at which time the acceleration module is enabled to achieve progress improvement by designing resource reinforcement strategies, such as increasing shifts, increasing construction personnel, and increasing related equipment investment to quickly improve construction speed. If no, it means that the current progress exceeds the maximum duration progress category, at which time the quality module is enabled to achieve quality enhancement within the duration by designing quality improvement strategies, thereby further improving the standardization and overall construction quality of the entire construction operation under the premise of ensuring the duration.
[0035] In the resource reinforcement strategy, the following formula is used:
[0036] By analyzing the personnel factors, building material matching factors, and environmental factors in the current construction environment, the environmental factors, as objective factors, are uncontrollable, and the construction speed can be improved by increasing the number of construction personnel and simultaneously increasing the number of building materials and related construction equipment.
[0037] The executable contents in the quality improvement strategy include: 1. Increasing the number of related construction processes, such as increasing the finishing cycle of related construction equipment, repeating the work in key construction areas 2-3 times, and setting different construction precision parameters for different materials; 2. Extending the gap time of related construction steps, such as appropriately extending the cooling and solidification time during pipe welding or concrete structure pouring, extending the temperature control to 150+10 degrees Celsius for 30 minutes in the welding process for high-carbon steel pipes, adjusting the slow cooling time after stainless steel welding to natural cooling for 48 hours to ensure component strength, extending the form removal time of mass concrete to 85% of the design strength, and extending the steam curing period to 10 days from 7 days during winter construction; 3. Reducing the construction shift frequency of construction personnel, such as changing from a three-shift system to a two-shift system to reduce work time, while supporting the establishment of a fatigue monitoring system to assess worker status in real time, implementing cross-operation management, setting AB corner rotation system for key positions, implementing "work-rest" work system for complex processes, and establishing a training system to improve single operation efficiency.
[0038] The execution strategy of S3 is: Step 1: Material inventory data acquisition; Step 2: Derive the incremental speed of consumables based on construction speed and production speed ; Step 3: If yes, it means that the inventory is within a safe range, and the current progress is maintained; If no, it means that the inventory is in a changing phase, and further differentiated judgment is made whether or not; if yes, it means that the inventory is in the growth stage, at this time, combined with the construction progress model, if the actual progress ≤ standard progress, the construction speed is increased, if the actual progress > standard progress, the production speed is reduced; if no, it means that the inventory is in the consumption stage, at this time, combined with the construction progress model, if the actual progress ≥ standard progress × (1+α), the construction speed is reduced, if the actual progress ≤ standard progress × (1-α), the material production speed is increased, and finally the construction progress adjustment is realized, and the construction progress adjustment will affect the change of material inventory, realizing the cycle control.
[0039] When controlling the inventory, due to the non-linear proportion of construction progress and consumable consumption, the consumption speed and demand of materials are different in different construction cycles, therefore, when dividing the construction progress, the progress needs to be divided according to different construction stages, which can be roughly classified as high-consumable stage and low-consumable stage, and the corresponding material consumption and construction progress relationship function is designed in the corresponding stage, which can be expressed as:
[0040] wherein represents the total material demand in unit time t cycle; is the proportional coefficient obtained by normalizing the relationship function between construction progress and material consumption speed.
[0041] Because the material consumption speed is different and the material demand is different in different cycles, therefore, in the inventory model and material production progress model; when the time point of the construction progress model approaches the high-consumable stage, the production speed is increased to expand the inventory, and the material daily turnover is increased; when the time point of the construction progress model approaches the low-consumable stage, the production speed is reduced to reduce the inventory, and the material daily turnover is reduced.
