Exemplary method

As shown in fig. 1, an embodiment of the present invention provides a method for controlling production of a prefabricated part, specifically, the method includes the following steps:

step S100, a component assembly to be produced and a production line assembly are obtained, wherein the component assembly to be produced comprises a plurality of target prefabricated components, the production line assembly comprises a plurality of component production lines, and one component production line comprises a plurality of production devices and at least one production material storage space.

Specifically, the target prefabricated parts are prefabricated parts to be produced, and the set of the prefabricated parts to be produced is a set formed by the target prefabricated parts. It should be noted that the set of components to be produced includes one or more (in this embodiment, a plurality of) target prefabricated components, and each target prefabricated component may be the same or different (i.e., may be the same component or may be different components), and is not limited specifically herein.

In the present embodiment, the above-mentioned target prefabricated parts are parts used in performing a prefabricated construction process, such as steel, wood or concrete parts previously manufactured in a factory or on site according to design specifications. The production line set is a set of all component production lines that can be used to manufacture the target prefabricated component, one component production line includes a plurality of production devices and at least one production material storage space, in this embodiment, a production material storage space is taken as an example, but not specifically limited, when one component production line corresponds to a plurality of production material storage spaces, the total capacity of the production material storage space corresponding to the component production line is the sum of the capacities of all production material storage spaces corresponding to the component production line. The production equipment is used for producing the components, and it should be noted that at least one production equipment is required for producing one target prefabricated component, and a plurality of production equipments are required for cooperation in the production process of part of target prefabricated components.

Further, in this embodiment, different component production lines are disposed at different positions, and the production devices and the arrangement sequences thereof included in the different component production lines may be the same or different, for example, a first component production line may include a production device a, a production device B, a production device C, and a production device D that are sequentially disposed, a second component production line may be disposed at another position, but the production devices and the arrangement sequences thereof included therein are the same as those of the first component production line, and a third component production line may include different production devices and/or different arrangement sequences of the production devices, for example, a third component production line may include a production device D, a production device a, a production device B, a production device E, and a production device a that are sequentially disposed, it should be noted that the same production device may also be included in the same device production line, which is not specifically limited herein.

In this embodiment, the acquired to-be-produced component set is used to indicate which target structural components need to be produced and the type of each target structural component, and the acquired production line set is used to indicate data of available component production lines. It should be noted that the prefabricated part production control method in this embodiment is used for optimizing and controlling the production process of the prefabricated part, and may also be applied to optimizing and controlling the production process of other components, members, devices, apparatuses, and the like in the actual use process, and is not limited specifically herein.

Step S200, obtaining a continuous working time length threshold corresponding to each of the production devices, and obtaining a target device set corresponding to each of the target prefabricated components, respectively, where one of the target prefabricated components corresponds to at least one target device set, and one of the target device sets is composed of a group of production devices required for completing production of the target prefabricated component.

The continuous working time length threshold corresponding to the production equipment is the maximum continuous working time length of the production equipment, and can be preset according to factors such as the actual model of the production equipment, the working current, the working voltage and the operating environment, and can also be adjusted in real time according to the actual requirement, which is not specifically limited herein. Specifically, in order to protect each production device and avoid burning out or other damages caused by overhigh temperature due to overlong working time, a corresponding continuous working time threshold is obtained to constrain the continuous working time of the production device.

The target equipment set is a set of production equipment required for producing the target prefabricated part. It should be noted that, for a target prefabricated component, there may be multiple production modes, where different production modes correspond to different required production devices, and one production mode corresponds to one target production device set, where one target production device set includes one or more production devices. For example, one target component has three production modes, the first mode can complete production only by using the production equipment a, and the corresponding target production equipment set only comprises the production equipment a; similarly, in the second mode, the production equipment B and the production equipment C are required to complete production together, and the corresponding target production equipment set includes the production equipment B and the production equipment C; in the third mode, production equipment B, production equipment D, and production equipment E are required to complete production together, and the corresponding target production equipment set includes production equipment B, production equipment D, and production equipment E. Therefore, multiple target equipment sets corresponding to the target prefabricated parts are obtained, the optimal production mode can be selected in the optimization calculation process, the optimization effect is improved, and the production requirement is better met.

And step S300, acquiring an optimization target and a production constraint condition according to the component set to be produced, the production line set, each continuous working time threshold and each target equipment set.

The optimization target comprises minimum overall energy consumption and minimum overall construction period, the overall energy consumption is the sum of energy consumption corresponding to all component production lines in the production line set in the process of producing all target prefabricated components in the component set to be produced, the overall construction period is consumption time corresponding to a production starting time and a production ending time, the production starting time is the time when a first target prefabricated component starts to produce, the production ending time is the time when a last target prefabricated component finishes producing, the production constraint conditions comprise a production line resource capacity constraint, a target device constraint and a device continuous working time constraint, the production line resource capacity constraint is used for limiting the volume of materials consumed when each component production line produces the target prefabricated component to be not more than the total capacity of a production material storage space corresponding to the component production line, the target device constraint is used for limiting all production devices in any one target device set corresponding to the target prefabricated component in the component production line selected by the target prefabricated component, and the device continuous working time constraint is used for limiting the continuous working time corresponding to each production device to be not more than a continuous working threshold corresponding to the production device.

Specifically, the above-mentioned optimization target is a target to be optimized in performing the prefabricated part production control process, such as a target to achieve the lowest overall energy consumption and the shortest overall construction period, and may include other targets to be achieved, which are not specifically limited herein. Specifically, the total construction period is a time period (i.e., a total production period) required from the start of production of the first produced target prefabricated member (i.e., the first target prefabricated member) to the completion of production of all the target prefabricated members (i.e., the completion of production of the last produced target prefabricated member).

The production constraints are some limitations in the production process, and the production constraints are determined according to actual conditions, for example, if the size of the production material storage space corresponding to one component production line is limited, the resources (i.e. raw materials for producing the target prefabricated component) that can be stored are also limited, and in the actual production process, the materials used by the component production line cannot exceed the corresponding limitations. Preferably, in consideration of a certain material loss in the production process, the production constraint conditions specifically limit the material volume consumed by the component production line when producing the target prefabricated component to be not more than the product of the total capacity of the production material storage space corresponding to the component production line and a preset loss rate (for example, 90%, the loss rate may be calculated according to the loss rate of the production equipment included in the component production line, or may be adjusted in real time), so as to ensure that the material is sufficient and avoid that the sufficient material cannot be stored due to the capacity limitation.

The target equipment constraint is used for limiting that a component production line selected during production of the target prefabricated component necessarily comprises a group of production equipment capable of completely producing the target prefabricated component, and is beneficial to ensuring that each target prefabricated component can be completely produced. Meanwhile, if any production equipment is operated continuously for too long time, faults may occur, for example, the equipment may be burnt out due to too high temperature caused by too long continuous operation time, so that the continuous operation time of each production equipment needs to be limited. It should be noted that, the continuous operation time length thresholds corresponding to different production devices may be different, and may be set and adjusted according to actual requirements, which is not specifically limited herein. In an application scenario, the continuous working time length thresholds of all production devices are set to be the same so as to be convenient for calculation and processing, the optimization calculation difficulty is reduced, and the control efficiency is improved.

In an application scenario, the production constraint condition further includes a production line energy consumption constraint, where the production line energy consumption constraint is used to limit the energy consumption corresponding to each of the component production lines when producing the target prefabricated component to be not greater than a preset maximum energy consumption value of the component production line.

Specifically, in the actual production and application process, the energy consumption of each component production line needs to be balanced as much as possible to achieve energy consumption balance, and the energy consumption balance that affects the whole production environment due to overhigh energy consumption of part of lines (namely part of component production lines) is avoided. Therefore, in this embodiment, a preset maximum energy consumption value is preset for each component production line, specifically, the preset maximum energy consumption value may also be set according to the capacity of the energy storage power supply corresponding to the component production line, and may also be adjusted in real time according to actual requirements, which is not specifically limited herein.

In this embodiment, the optimization objective further includes that the overall carrying distance is the shortest, where the overall carrying distance is the sum of the carrying distances corresponding to the objective prefabricated components, and the carrying distance corresponding to one objective prefabricated component is the distance between the component production line for producing the objective prefabricated component and the preset placement area corresponding to the objective prefabricated component.

Specifically, after a target prefabricated part is produced on a component production line, the target prefabricated part cannot be placed on the component production line all the time, and the target prefabricated part needs to be transported to a corresponding preset placing area, so that the subsequent use is facilitated, and meanwhile, the next target prefabricated part is produced on the component production line conveniently. In this embodiment, a linear distance between the component production line and the preset placement area is used as the corresponding carrying distance, and in an application scenario, when carrying is performed by a preset automatic carrying robot, a route corresponding to a planned route or an actual route of the automatic carrying robot may be used as the corresponding carrying distance, which is not specifically limited herein.

And S400, according to the optimization target and the production constraint condition, performing optimization solution through a preset genetic algorithm and obtaining a production strategy corresponding to the component set to be produced.

In this embodiment, the preset genetic algorithm is a multi-population dynamic evolution algorithm, and in the actual use process, other optimization algorithms may also be used, which is not specifically limited herein.

Specifically, the performing optimization solution according to the optimization objective and the production constraint condition by using a preset genetic algorithm to obtain a production strategy corresponding to the component set to be produced includes: constructing an objective function based on the optimization objective, wherein the objective function is a sum of the total energy consumption, the total construction period, and the total handling distance; and taking the minimum function value obtained by the objective function as a target, and according to the production constraint condition, carrying out optimization solution through a preset genetic algorithm to obtain a production strategy corresponding to the component set to be produced.

In the present embodiment, the total energy consumption, the total construction period, and the total transport distance are directly used as the objective function. In the actual use process, corresponding weight values can be set for the total energy consumption, the total construction period and the total carrying distance according to the actual requirements controlled by the user, and the total energy consumption, the total construction period and the total carrying distance are weighted and summed to be used as a target function, so that accurate control is more convenient to perform and the actual requirements are met. For example, in the production and processing process, energy conservation and emission reduction are the most concerned requirements of users, that is, users pay more attention to whether the total energy consumption is the lowest or not, and the influence of the total energy consumption is larger, so that a larger weight value is set for the total energy consumption. For another example, in another application scenario, the target prefabricated part needs to be produced and finished as soon as possible to put it into use, and the production schedule needs to be accelerated, that is, the user pays more attention to the production period, and a larger weight value is set for the overall period.
