Description

Technical Field

[0001] The invention belongs to the technical field of workshop logistics, and in particular relates to a method and device for generating a workshop logistics model. Background Art

[0002] The workshop logistics system integrates automation technology and information technology to realize the automatic handling and tracking of materials in the workshop, which plays a vital role in improving workshop production efficiency, reducing costs, and reducing waste. The design of the workshop logistics system often needs to be adjusted and expanded according to changes in production needs. The current research on workshop logistics is also limited to the layout of the workshop production logistics system, and most of them are planned and drawn in the form of two-dimensional modeling. Only a few three-dimensional modeling methods are also converted from two-dimensional drawings to three-dimensional static models.

[0003] For example, patent application CN116702454A provides a modeling method, device, electronic device and storage medium for logistics layout, including: reading the first coordinate and type of the point block in the initial logistics design diagram; determining the entity corresponding to the point block in the simulation modeling software based on the first coordinate and type, thereby obtaining the initial logistics layout diagram; obtaining the intermediate logistics layout diagram based on the associated equipment associated with the entity layout entity of type in the initial logistics layout diagram; establishing the edge relationship between the entity and the first entity adjacent to the entity in the intermediate logistics layout diagram, thereby obtaining the target logistics layout diagram. The technical solution provided by this patent can reduce the dependence on professional simulation personnel and labor costs, greatly shorten the simulation cycle, and improve the efficiency of logistics layout modeling.

[0004] In the current research, workshop logistics remains at the static analysis stage, and the layout of the workshop logistics system will be analyzed with the simulation of workshop production. For example, patent CN117077458B provides a method and device for constructing a dynamic simulation model of an electronic product production line, the method includes: based on the process route of the electronic product production line, providing the layout information, manufacturing information and logistics task information of the electronic product production line; according to the layout information of the electronic product production line, building an electronic product production line layout model; according to the electronic product production line layout model, combined with the preset coding strategy, providing the layout link parameters of the electronic product production line, the layout link parameters are used to associate the layout information and manufacturing information of the electronic product production line; embedding a calling module in the layout model of the electronic product production line to obtain a dynamic simulation model of the electronic product production line, and the calling module is used to call the logistics task information according to the layout link parameters. This scheme quickly and accurately obtains a dynamic simulation model from the layout model of the electronic product production line, has extremely strong universality, and improves the dynamic simulation effect of the electronic product production line.

[0005] However, the layout design of the logistics system and the simulation analysis of the logistics system are operated independently. There is a separation between layout design and simulation analysis. The data between them cannot be directly transmitted. There is a lack of integration and fusion. The switching and data synchronization between the layout equipment system and the simulation system are difficult and prone to errors. It is impossible to effectively cope with complex and changeable logistics operations and it is difficult to meet the needs of modern factory workshops for efficient and flexible logistics systems.

[0006] Therefore, how to build a workshop logistics model to achieve the integration of layout design and simulation analysis in the workshop logistics system and efficient and accurate data information transmission is an urgent problem to be solved by technical personnel in this field.

[0065] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two.

[0067] It should also be noted that the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the commodity or device including the elements.

[0068] In order to realize the integration of layout design and simulation of workshop logistics system, it is urgent to seamlessly connect layout design and simulation analysis. The constructed workshop logistics model interacts and integrates the process and data of layout design and simulation analysis to improve the accuracy and efficiency of switching and data synchronization between the two stages. It can not only improve the efficiency of workshop logistics planning, but also simultaneously verify and optimize the rationality of workshop logistics planning.

[0069] For the workshop logistics model that integrates layout design and simulation analysis, it is necessary to combine the advantages of the visualization of the three-dimensional layout of the logistics system and the dynamic analysis of simulation, and connect the advantages of the two through parametric modeling and information interaction. In addition, the workshop logistics model after integrated layout design and simulation analysis can be used for the layout of the logistics system, and can also optimize and iterate the layout of the logistics system based on simulation analysis, realizing the flexibility of logistics system planning and design, and can respond to changing workshop logistics needs and workshop production environment through rapid response and adjustment, expanding the scene applicability of the workshop logistics model.

[0070] like Figure 1 As shown, the present invention provides a device for generating a workshop logistics model, which specifically includes:

[0071] A logistics layout model building unit, used to obtain workshop layout information, build a logistics layout model, and provide first logistics layout information;

[0072] And, based on workshop logistics simulation analysis, optimize the logistics layout model;

[0073] The logistics simulation analysis unit is used to convert the first logistics layout information to form the second logistics layout information, provide a logistics simulation model, and perform workshop logistics simulation analysis in combination with the second logistics layout information and the simulation task information.

[0074] The present invention transforms logistics layout information, connects logistics layout models with logistics simulation analysis, constructs a workshop logistics model, solves the problems of insufficient automation and low flexibility in the design of workshop logistics systems, and improves the overall performance and reliability of the designed workshop logistics system.

[0075] For the logistics layout model building unit, the equipment layout information of the workshop and the modeling information such as the production demand of the workshop are used as input information, and the logistics path planning information, logistics track information, storage planning information and transfer information for building the logistics layout model are analyzed and given. The output is the logistics track arrangement displayed by the logistics layout model (such as Figure 2 As shown), logistics scheduling logic.

[0076] like Figure 3 As shown, the workshop layout information is obtained and the logistics layout model is constructed, which includes:

[0077] Determine logistics route planning information based on the equipment layout information of the workshop;

[0078] Combined with logistics track information, based on logistics path planning information, determine the logistics track layout;

[0079] Based on the production needs of the workshop and the logistics track layout, the logistics scheduling logic is determined, and the reserve planning information and transfer information are given to build a logistics layout model.

[0080] Among them, logistics path planning information is the transportation path information of logistics in the workshop, reserve planning information is the location and quantity information of reserve components, and transfer information is the number of transfer equipment and transfer logic information. In addition, the equipment layout information of the workshop includes the number of equipment in the workshop and the location information of each equipment.

[0081] The construction of the logistics layout model of the workshop can be carried out in a conventional modeling platform or modeling software (for example, Archicad software). The logistics path planning information, logistics track layout, storage planning information and transfer information are presented in the form of a physical model in Archicad software, and the logistics scheduling logic can be presented in the form of a plug-in.

[0082] like Figure 4 As shown, the first logistics layout information is given, specifically including:

[0083] Based on the logistics layout model, determine the output component type and component attributes;

[0084] Calling the correspondence between the output element information pre-configured in the logistics layout model and the component type and component attribute, matching the output element information of the logistics layout model, and providing the first logistics layout information;

[0085] The output element information is information output by the logistics layout model. The first logistics layout information includes component type information and component attribute information. The corresponding relationship between the output element information and the component type and component attribute is pre-configured by sequentially determining the matching relationship between the output type and the output element information, and the mapping relationship between the output attribute and the output element information. Specifically, it is expressed as:

[0086]

[0087] For the output element E i The first logistics layout information, E i is the i-th output element information, The component attributes and output element information E of number 1, ..., j i The mapping function between A1,…,A j is the component attribute numbered 1, ..., j, M A→T () is the matching function between the component type and the component attributes numbered 1, ..., j, T m is the mth component type that matches the component attributes numbered 1, ..., j, and T is a set of component types.

[0088] Among them, component types include logistics tracks, storage components and transfer equipment, and component attributes include name, location and size.

[0089] In a specific application scenario, the output element information provided by the logistics layout model is output in the form of a document.

[0090] In order to realize the data transmission between the workshop logistics layout and the simulation analysis, the standardized processing of logistics data is realized by setting the information data normalization conversion between the output element information and the component type and component attributes. For example, when the component type is a logistics track, the component attributes are the attributes of the logistics track, including the name, position and size of the logistics track. The position of the logistics track is represented by the coordinate position, and the size of the logistics track is generally the length, radius and other information. Of course, the direction can also be included. In order to improve the efficiency of the normalization conversion of information data, mirroring can also be used to represent two logistics tracks with the same length and the same name in the positive and negative directions.

[0091] like Figure 5 As shown, the first logistics layout information is converted to form the second logistics layout information, which specifically includes:

[0092] Array processing is performed on the first logistics layout information to provide logistics layout information to be processed;

[0093] Based on the logistics simulation requirements, the logistics layout information to be processed is decoupled to convert the information format to form the second logistics layout information, wherein the second logistics layout information includes component type information and component attribute information. The decoupled processing specifically includes:

[0094] Determining a decoupled target format type based on the format type of the second logistics layout information;

[0095] Through the mapping relationship, the logistics layout information to be processed is converted to adapt to the target format type.

[0096] The first logistics layout information after standardization is then processed into an array to realize the correspondence of parameterized information of component types and attributes of each component. The array can be in the form of a string or a numerical value. The processed first logistics layout information will form a standardized and systematic array information set in the form of an array. At this time, the array information set is the logistics layout information to be processed.

[0097] The conversion between the first logistics layout information and the logistics layout information to be processed is as follows: Figure 6 As shown, the first logistics layout information is processed into an array to provide logistics layout information to be processed, which specifically includes:

[0098] Based on preset rules, matching and extracting the array in the first logistics layout information to form multiple logistics layout information sets;

[0099] Format each logistics layout information set and provide the logistics layout information to be processed.

[0100] Specifically, the preset rules are expressed as follows:

[0101]

[0102] Among them, f[ ] is the rule function, T m is the mth component type that matches the component attributes of number 1, ..., j, A1, ..., A j is the component attribute numbered 1, ..., j, s() is the component type search function, sorted[ ] is the sorting function, M A→P () is the matching function between the position attribute and the component attributes numbered 1, ..., j, M A→D () is the matching function between the size attribute and the component attributes numbered 1, ..., j, M A→O () is the matching function between the direction attribute and the component attributes numbered 1, ..., j, M A→R () is the matching function between the angle attribute and the component attributes numbered 1,…,j.

[0103] Among them, component type search function, sorting function, matching function between position attributes and component attributes, matching function between position attributes and component attributes, matching function between size attributes and component attributes, matching function between direction attributes and component attributes, and matching function between angle attributes and component attributes can be pre-set to realize component type search and related matching. Here, the specific types of search function, sorting function, and matching function are not limited.

[0104] For the array processing of the first logistics layout information, it is necessary to first identify the array in the first logistics information, and match and extract the identified array, and then form a logistics layout information set. Finally, the logistics layout information set is arranged according to a preset format to meet the transmission requirements from layout to simulation analysis.

[0105] Considering the position and arrangement relationship of the entity model in the logistics layout model, the array processing of the first logistics layout information needs to follow the preset rules. The preset rules not only provide the matching of component types and component attributes, but also provide the order between the attributes of each component, thereby avoiding the conflict of the layout information of each component in the array processing, which leads to confusion in the conversion and transmission of the first logistics layout information to the second logistics layout information.

[0106] For example, in an application scenario, such as Figure 7As shown, the component type search function is used to determine that the component type to be arrayed is the basic track (arcpath, specifically the arc type in the basic track), and the corresponding prototype track Track0 is created, named path_196, and the track number is 196. Then the component type is matched with the component attributes of the basic track: the first step is to match the position attribute of the basic track to obtain the position coordinates (0, 0, 0); the second step is to match the size attribute of the basic track to obtain the length information (0.7853981634); the third step is to match the direction attribute of the basic track to obtain the direction information (first forward, then mirror inversion); the fourth step is to match the angle attribute of the basic track to obtain the angle information (turn 270°). Finally, the formatting of the above logistics layout information set can be embedded in the processing of the appearance feature information (the curvature is -90° and the radius is 0.5), thereby giving the final logistics layout information to be processed.

[0107] Determining the mapping relationship by the decoupled target format type can be considered as the process of converting each component type and each component attribute in the logistics layout information to the array type required for logistics simulation analysis. The type of mapping relationship may be different in different application scenarios, and the specific type of mapping relationship is not limited here. Figure 7 As shown, after mapping the to-be-processed logistics layout information to the second logistics layout information, a physical model for simulation analysis is obtained, and the physical model is in one-to-one correspondence with the physical model in the logistics layout model.

[0108] From the second logistics layout information to the logistics simulation model, and to run the logistics simulation model, it is also necessary to embed simulation task information, which includes workshop from to information and logistics scheduling logic;

[0109] Combine the second logistics layout information and simulation task information to perform workshop logistics simulation analysis, including:

[0110] Reconstruct the logistics simulation model based on the second logistics layout information, the workshop from and to information, and the logistics scheduling logic;

[0111] Determine the attribute parameters and flow rate of the transfer equipment used for logistics simulation, set simulation events and simulation event update logic, run the logistics simulation model, and give simulation index data, which is specifically expressed as:

[0112]

[0113] Among them, KI is the simulation index data set, C1, ..., C n is the simulation index function numbered 1, ..., n, C is the set of simulation index functions, P1, ..., P nare the attribute parameters of the transfer equipment numbered 1, ..., n, P is the attribute parameter set of the transfer equipment, and Q is the flow rate of the transfer equipment.

[0114] The workshop from-to information is the number and transfer path of logistics transfer between each process in the workshop. Generally, the workshop from-to information is presented in the form of a from-to form.

[0115] Regarding the construction of the logistics simulation model, specifically, based on the second logistics layout information, the workshop from to information and the logistics scheduling logic, the logistics simulation model is reconstructed, specifically including:

[0116] Constructing a system module based on the second logistics layout information;

[0117] Combine the workshop information and logistics scheduling logic to generate multiple simulation events and build a scheduling module;

[0118] Based on the component type information and component attribute information, the mapping relationship between the system module and the scheduling module is established, and the logistics simulation model is reconstructed.

[0119] The attribute parameters of the transfer equipment include the speed and load capacity of the transfer equipment, and the simulation event is the attribute parameter value of the transfer equipment determined by the time frame;

[0120] The simulation event update logic specifically includes: updating the simulation event based on the update of component type information and / or component attribute information.

[0121] For logistics simulation, you can use conventional simulation platforms or simulation software (for example, AnyLogic software, Simio software, etc.) to reconstruct the above logistics simulation model, adjust the architecture, and run it.

[0122] In the logistics simulation analysis stage, the simulation index data is given through the second logistics layout information and simulation parameters (property parameters of transfer equipment, flow), scheduling logic (simulation events and updated simulation events), and the logistics layout model is optimized based on the analysis of the simulation index data.

[0129] (2) In order to realize the data transmission between the workshop logistics layout and the simulation analysis, the standardized processing of logistics data is achieved by setting the standardized conversion of information data between the output element information and the component type and component attributes.

[0130] (3) Considering the position and arrangement relationship of the entity model in the logistics layout model, the array processing of the first logistics layout information needs to follow the preset rules. The preset rules not only provide the matching of component types and component attributes, but also provide the order between the attributes of each component, thereby avoiding the conflict of the layout information of each component in the array processing, which leads to confusion in the conversion and transmission from the first logistics layout information to the second logistics layout information.
