AI Technical Summary
In prefabricated construction, since completely free of stacking is an ideal state, there is still a stacking phenomenon on the construction site in actual production, which leads to the supply-side scheduling being more important. However, the existing scheduling methods are mostly based on experience, with complex influencing factors, making it difficult to estimate the production rhythm, and supply is difficult to get close to the ideal state.
A field dispatching system that dynamically balances the consumption and supply-side transportation volume of construction sites is adopted, including on-site storage data acquisition module, dynamic balance module, timing module, material delivery data acquisition module and schedule module. By collecting and analyzing data in real time, the quantity and type of material supply are calculated, the supply rhythm is adjusted, and dynamic balance is achieved.
By dynamically balancing the supplement and consumption of the supply end and on-site, the overall scheduling results are closer to the ideal pile-free state, saving construction period, avoiding excessive pile-up problems on-site, and improving the safety and production efficiency of the construction site.

Abstract
Description
Technical Field
[0001] The present invention relates to the field of construction scheduling, and in particular to a site scheduling system and method based on prefabricated construction. Background Art
[0002] Construction scheduling is a means of commanding construction production and is the coordination center for all links, professions, and types of work in the entire construction process. The scheduling department is a powerful assistant for leaders at all levels of construction enterprises to organize and manage construction. The task of construction scheduling is to establish and maintain normal construction order and procedures, create construction conditions, supervise and control the implementation of the plan, and constantly organize new balances to ensure the full realization of the construction plan and various technical and economic indicators according to the construction plan and construction organization design.
[0003] Prefabricated construction is different from conventional construction methods. It transfers a large amount of on-site work in traditional construction methods to the factory. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.
[0004] This leads to the advantage of prefabricated construction having a more controllable construction site. At the same time, under ideal conditions, the construction site can avoid on-site material stacking according to the formulation of transportation and production rhythm, further increasing the safety of the construction site and avoiding uncontrollable factors. However, since completely avoiding material stacking is an ideal state, in actual production, prefabricated construction sites still inevitably have material stacking, so the supply-side to site scheduling is relatively more important, but the current scheduling methods are mostly based on experience, and the influencing factors in actual construction are changeable and complex, so the actual production rhythm is difficult to predict and the supply is difficult to approach the ideal state.
[0005] Therefore, a site dispatching system based on prefabricated construction is needed to solve the above problems. Summary of the invention
[0006] The present invention aims to solve the problem that in the prior art, since completely avoiding material stacking is an ideal state, in actual production, material stacking is still inevitable at the prefabricated construction site. Therefore, scheduling from the supply end to the site is relatively important. However, the current scheduling methods are mostly based on experience. The influencing factors in actual construction are changeable and complex. Therefore, the actual production rhythm is difficult to predict and the supply is difficult to approach the ideal state. A site scheduling system based on prefabricated construction is provided, which adopts a dynamic balance between the consumption at the construction site and the transportation volume at the supply end to solve the above problems.
[0007] The present invention provides a site dispatching system based on prefabricated construction, comprising a site storage data acquisition module, a dynamic balance module, a timing module, a material dispatching data acquisition module and a schedule module. The schedule module is used to input the construction plan according to the construction timeline and estimate the types and quantities of prefabricated components required on site. The on-site storage data collection module is used to collect the types and quantities of prefabricated components stored on the construction site in real time. The timing module is used to record the duration from the start of construction to the present. The material delivery data collection module is used to record the real-time supply data of each prefabricated component supplier. The dynamic balance module is used to calculate the quantity and type of materials to be supplied by each prefabricated component supplier to the construction site in the next step based on the construction site storage capacity through the fitting weight of the plan and the actual. The timing module transmits the time data to the on-site storage data acquisition module and the material dispatch data acquisition module. The on-site storage data acquisition module and the material dispatch data acquisition module transmit the material information with timestamp to the dynamic balance module. The schedule module transmits the expected quantity and time information to the dynamic balance module.
[0008] The present invention provides a method for on-site dispatching based on prefabricated construction, comprising the following steps: S1. Determine the construction plan and enter the construction plan duration, estimated total number of materials and daily consumption into the planning table module; S2, the schedule module divides the time periods of the same type of materials required in the construction plan and which are coherent in time into construction plan segments; S3, determining the on-site storage space information and calculating the maximum delivery time interval of each construction plan segment according to the on-site storage space information and the time length of each construction plan segment, and calculating the minimum delivery times of each construction plan segment given the maximum time delivery interval; S4. Take the lowest common multiple of the minimum delivery times as the estimated delivery times of the overall delivery plan, and divide the construction plan into delivery segments of equal duration and allocate the materials required for the delivery segments according to the estimated delivery times; S5, determining whether the single-item delivery volume in the delivery segment of equal duration exceeds the maximum carrying capacity of the corresponding supply end, if so, then balancing the carrying capacity is performed and then proceeding to step S6, otherwise, proceeding to step S6; S5. Divide the materials required for the distribution section into daily consumption according to the number of construction days; S6. Each supplier conducts trial delivery to the construction site; S7, the on-site storage data collection module collects the actual daily material consumption and performs a proportional calculation with the estimated daily consumption of the construction plan; S8. Determine whether the calculation result of the current day's ratio is greater than 1. If so, use the data as the current day's adjustment ratio. Otherwise, assign 1 as the current day's adjustment ratio. S9, taking the current day as the maximum value node, making a positive integer discrete half-normal distribution along the time axis in the starting direction, and taking the probability value of the positive integer discrete half-normal distribution as the time coefficient; S10. Calculate the overall distribution quantity adjustment coefficient. The calculation method is as follows: Take the daily time coefficient multiplied by the adjustment ratio of the corresponding date multiplied by the daily estimated daily consumption as the daily ingredient adjustment parameter, and take the average of all daily ingredient adjustment parameters; S11. The overall distribution quantity adjustment coefficient is taken as the distribution frequency adjustment parameter; S12, obtaining the current theoretical delivery times through the cargo distribution times adjustment parameter and the cargo distribution times adjustment parameter; S13, rounding up the current theoretical delivery times as the actual delivery times; S14, allocating materials required for the next delivery segment according to the actual number of delivery times; S15, determine whether all deliveries are completed, if yes, proceed to step S17, otherwise proceed to step S16; S16, determine whether it is a delivery date, if yes, proceed to step S7 after delivery, otherwise proceed directly to step S7; S17. Complete on-site scheduling of prefabricated construction.
[0009] The on-site dispatching method based on prefabricated construction described in the present invention is, as a preferred embodiment, a specific method for balancing the carrying capacity in step S5 is: Calculate the ratio coefficient between the single-item delivery quantity and the maximum carrying capacity of each supply end in a delivery segment of equal duration; Select a proportionality factor greater than 1 and calculate the least common multiple of the proportionality factors; The lowest common multiple of the proportional coefficients is taken as the final proportional coefficient, multiplied by the number of deliveries and rounded up.
[0010] In the on-site dispatching method based on prefabricated construction described in the present invention, as a preferred method, the trial delivery method of step S7 is: Based on the daily consumption, materials are calculated and obtained to fill the storage space of the construction site in the order of the construction plan, and each supply end delivers the currently required materials to the construction site.
[0011] The on-site scheduling method based on prefabricated construction described in the present invention is, as a preferred method, a material delivery data acquisition module that monitors the maximum carrying capacity of each supply end in real time and ensures that the maximum carrying capacity is always lower than the estimated carrying capacity of the materials required for the next distribution segment.
[0012] The beneficial effects of the present invention are as follows: This method makes the overall scheduling result closer to the ideal state of no material stacking by dynamically balancing the replenishment and consumption of the supply side and the site. Combined with the characteristics of prefabricated construction, the on-site material demand of prefabricated construction is relatively fixed due to assembly, which makes the supply rhythm of the supply side relatively fixed based on the assembly line, laying the foundation for the rhythm adjustment of the overall on-site construction. On this basis, through time and space considerations, the overall construction scheduling is kept in a stable production rhythm, saving construction time while avoiding the problem of excessive material stacking on site.
