Description

Technical Field

[0001] This application relates to the field of system modeling and simulation technologies, and in particular to a logical behavior modeling method, device, equipment, and medium based on an entity activity diagram. Background Art

[0002] Modeling and simulation is a new discipline. Modeling is to abstract data, processes, constraints, etc. in reality into various models, and simulation is the execution of the models.

[0003] Simulation modeling can be broadly classified into entity modeling and behavior modeling. Behavior refers to the impact on internal or external states. Behavior is persistent, has a certain time period, and has three major stages: occurrence, impact, and end. Logical behavior is a type of behavior, mainly depicting the logical relationships between behavior and entities, and between behavior and behavior, including influence relationships, causal relationships, dependency relationships, etc. The logical relationships between entities are not depicted in logical behavior modeling.

[0004] The current graphical logical behavior modeling methods mainly include the following: finite state machine, behavior tree, activity diagram, business process flowchart, and Petri net diagram.

[0005] However, the above methods all have certain problems and cannot meet more diversified requirements;

[0006] 1. Lack of code-free executable modeling ability. The current modeling methods mainly adopt graphical modeling techniques that can automatically generate code frameworks and fill in the code inside the implementation logic. It is a support for low-code modeling. Model diagrams without code implementation do not have the ability to be executed. Therefore, code-free graphical executable modeling has not been achieved.

[0007] 2. Lack of the ability to express complex concurrent logic. The behavior tree is a tree structure, which is a specialized structure of the network structure. The description ability of the tree structure is limited compared to the network structure and can only describe behaviors with a limited action space. Although the finite state machine can perform hierarchical decoupling when describing complex behaviors and use state diagrams at different levels to represent state transitions, there are still problems such as state space explosion and complex and chaotic state transition connection lines. The activity diagram only describes the activity flow relationship and lacks the description of operations on numerical objects. The business process flowchart and the Petri net diagram adopt network structures, and the description ability has been improved, but the types of basic graphical elements in the two modeling methods are relatively simple, lacking logical encapsulation behind them, and the description of complex logic is limited.

[0008] 3. Lack of graphical description of the relationship between entities and behaviors. The fundamental requirement of behavior modeling is to depict the behavior triggering rules and the impact rules of behaviors on entity states. Currently, the mainstream logical behavior modeling methods generally adopt the "blackboard mechanism", and behaviors such as data flow and state change are carried out by reading and writing the blackboard, without graphical explicit representation. For the same behavior in different scenarios or conditions, the operations on values may also be different. Therefore, it is necessary to graphically describe the relationship between entities and behaviors to complete the logical behavior information encapsulated inside the behavior nodes. Summary of the Invention

[0009] Based on this, in view of the above technical problems, it is necessary to provide a logical behavior modeling method based on entity activity diagrams, which can realize the graphical, rapid and agile construction of multi-granularity logical behavior models.

[0053] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] As Figure 1 shown, a logical behavior modeling method based on an entity activity diagram provided by the present application, in one embodiment, includes the following steps:

[0055] Step 102: According to the modeling task, establish an entity activity diagram of the logical behavior; the basic elements of the entity activity diagram include nodes, node labels, connections, and layout elements; the types of entity activity diagrams include activity template diagrams and activity implementation diagrams.

[0056] Step 104: According to the basic elements of the entity activity diagram, model the activity template diagram to obtain a first node architecture attribute diagram, a first node label architecture attribute diagram, a first connection architecture attribute diagram, and a first layout element architecture attribute diagram.

[0057] Step 106: According to the basic elements of the entity activity diagram, model the activity implementation diagram to obtain a second node architecture attribute diagram, a second node label architecture attribute diagram, a second connection architecture attribute diagram, and a second layout element architecture attribute diagram.

[0058] Step 108: Model the logical behavior of the modeling task according to the first node architecture attribute diagram, the first node label architecture attribute diagram, the first connection architecture attribute diagram, the first layout element architecture attribute diagram, the second node architecture attribute diagram, the second node label architecture attribute diagram, the second connection architecture attribute diagram, and the second layout element architecture attribute diagram.

[0059] This method uses architecture attribute diagrams to describe the basic elements of the entity activity diagram. The basic elements are of four types, namely nodes, node labels, connections, and layout elements, and their architecture attributes are as Figure 2 shown.

[0060] The explanations of the basic elements are as follows:

[0061] Node: The most basic element that makes up the entity activity diagram, which can represent the types or instances of entities, activities, and attributes, and has multiple node types.

[0062] Node label: A systematic and discrete description of a node. A node can be attached with multiple labels. Among them, the data type label does not support set operations and Map mapping object operations for the time being, which simplifies the data type description.

[0063] Connection: Describes the relationship between nodes and has multiple connection types.

[0064] Layout element: An auxiliary element introduced to improve the human-computer interaction.

[0065] As Figures 3 to 6 shown is a detailed description diagram of the architecture attributes of each element.

[0066] As Figure 7 shown is an explanatory diagram of the style convention of the basic elements.

[0067] Table 1 Types of Connections

[0068] Connection type Connection description Trigger connection When the predecessor node is activated or completed, trigger the successor node to execute Pause connection When the predecessor node is completed, trigger the successor composite activity node to pause the activity Continue connection When the predecessor node is completed, trigger the successor composite activity node to continue the activity Stop connection When the predecessor node is completed, trigger the successor composite activity node to stop the activity Reference connection The end node is the reference relationship of the start node, and the end node is the start node Composite connection The end node is a part of the start node, and they are in a composite relationship with each other Data connection The connection for outputting the activity result, and output the activity result data to the end node Assignment connection Activate the constant node and change the property node of the constant node to this value Instance connection The constant node and the parent property node are in an instance relationship

[0069] For the convenience of connection identification, the connection type in the entity activity diagram is determined by the type of the starting node of the connection. To avoid ambiguity, the mapping relationship between nodes and connections is clearly shown in Table 2.

[0070] Table 2 Mapping Relationship between Nodes and Connections

[0071]

[0072] Based on the basic elements, an activity template diagram and an activity implementation diagram are established;

[0073] Activity template diagram: The activity template diagram is a type of entity activity diagram. The main objects it describes are the types of node elements, such as airplanes, vehicles, etc. The activity template diagram has interface nodes in modeling. Due to having interfaces, it can be combined with other models during the modeling process, thus realizing template reuse.

[0074] Activity implementation diagram: The activity implementation diagram is a type of entity activity diagram. The main objects it describes are the instances of node elements, that is, specific types, such as airplane 1, airplane 2, etc. The activity implementation diagram does not have external interface nodes. It can use the activity template diagram for combined model reuse and pass in specific model instances to realize entity activity diagram modeling.

[0075] The above-mentioned logical behavior modeling method, device, equipment and medium based on entity activity diagrams perform logical behavior modeling in a user-friendly and graphical way. It integrates entities, entity attributes and activities into one view, defines the basic elements of the entity activity view and their meanings, and focuses on depicting the dynamic relationships between activities, and between entities and activities. Through different combinations of elements, it can achieve flexible and convenient parallel activity modeling, and can more effectively display and edit concurrent behaviors. At the same time, while controlling complexity, it shows associated information as much as possible. There is a significant improvement in the flexibility and efficiency of logical behavior modeling compared to previous methods. The established logical behavior model can contain all execution information, thus realizing model-free executable modeling. This modeling method is a domain-independent modeling technology, and this technology and system can be widely applied in fields such as system simulation and system simulation, bringing social and economic value.
