Detailed Implementation

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 12 As shown, an environment profile generation method based on MBSE includes the following steps S101 to S107. Wherein: Step S101: Obtain mission data. The mission data includes the mission of the target equipment. The mission consists of at least one mission element. The mission data is a set of mission data of the equipment system to which the target equipment belongs. It is generally composed of elements such as combat location, combat time, mission objective, and combat environment. For example, the mission of a certain type of air defense missile weapon system is to perform all-weather strategic air defense missions in the southeast coastal area.

[0017] Step S102: The mission data is processed using an analysis method based on the Hall triple cone structure to transform the mission elements into a structured set of elements, which includes a set of equipment components and a set of environments. Specifically, this includes steps S201 to S204. Wherein: Step S201: Analyze the superior relationship of the target equipment in the mission data according to the subject hierarchy dimension to determine the functional type of the target equipment and the mission tasks to be performed; In step S201 of this application embodiment, the subject hierarchy dimension is "equipment system - combat unit - basic combat unit - equipment".

[0018] Step S202: Decompose the mission elements of the target equipment according to the time dimension, identify key activities, and read the scene environment parameters of each key activity; In step S201 of this application embodiment, the time dimension is "top-level mission - combat mission - combat scenario - element activities".

[0019] The purpose of implementation step S201 is to determine the associated objects of the target equipment in the equipment system within the environmental profile, namely the target equipment's superior basic combat unit, combat unit, and equipment system. Then, based on the mission data of the equipment system, the mission of the target equipment is decomposed layer by layer. For example, the mission of a certain type of conventional missile strike system is to carry out all-weather saturation strikes, precision strikes, and air defense support against the enemy along the southeast coast. According to the main hierarchical dimension, the mission of its subordinate air defense missile brigade is to carry out all-weather air defense support against the enemy along the southeast coast. Decomposed to its subordinate mobile air defense missile battalion, its mission is to carry out all-weather mobile air defense missions along the southeast coast. Further decomposed to the air defense missile weapon system, its mission is to carry out all-weather mobile air defense missions along the southeast coast, plus specific parameter requirements, etc.

[0020] Step S203: Based on the functional type of the target equipment and the mission tasks to be performed, associate the mission task elements with the specific equipment, identify the list of key activities that the target equipment needs to perform and the specific environmental parameters of each activity in the list of key activities.

[0021] Step S204: Based on the equipment activity list, specific environmental parameters, and equipment configuration information, the mission elements are formally described as a five-tuple, which includes the mission objective set, equipment component set, activity set, activity relationship set, and environment set.

[0022] Specifically, in step S102 of this application embodiment, the mission elements are transformed into a structured set of elements as shown below: ; In the formula, Represents a set of elements; , representing the set of objectives of a mission or task; , representing a collection of equipment components for a mission or task; , representing a set of activities related to a mission or task; , representing the set of relationships between activities related to a mission or task; A set of environments representing missions and tasks.

[0023] By implementing steps S201 to S204 above, this application, based on the Hall three-dimensional structure, systematically decomposes multi-level task elements such as system mission, phase tasks, sub-tasks, and activities from the forward link of "top-level mission - combat mission - combat scenario - element activities" and the organizational hierarchy of "equipment system - combat unit - basic combat unit - equipment," and combines the combat element dimension, time process dimension, and subject level dimension for multi-dimensional modeling. By formally describing the five-tuple elements of target, equipment, activities, inter-activity relationships, and environment, a clear and logically tight equipment mission model is constructed, ensuring comprehensive coverage from combat intent to specific execution activities, and providing a complete and consistent input basis for the environmental and operational condition analysis of equipment in different combat scenarios.

[0024] Step S103: Construct a natural environment meta-model of the target equipment based on the environment set; construct an equipment configuration and induced environment meta-model of the target equipment based on the equipment component set.

[0025] In step S103 of this application embodiment, constructing the natural environment meta-model of the target equipment based on the environment set includes: Using block definition diagrams as the modeling carrier, block elements are used to represent environmental factors in the environment set, and the attributes of block elements are used to represent the environmental parameters corresponding to the environmental factors to construct the natural environment meta-model of the target equipment.

[0026] like Figure 3 As shown, Figure 3 In this context, common natural environmental factors are represented by blocks, including temperature, humidity, rain, air pressure, wind, solar radiation, snow, salt spray, dust, and mold. Corresponding environmental attributes can be defined according to the environmental adaptability requirements of the top layer. For example, temperature-related environmental parameters include high temperature, low temperature / freezing, and temperature shock.

[0027] like Figure 4 As shown, in step S103 of this application embodiment, the step of constructing the equipment configuration and induced environment meta-model of the target equipment based on the equipment component set includes: The equipment configuration and induced environment meta-model of the target equipment are constructed using internal block diagrams as the modeling carrier, wherein: The target equipment is represented by a block element, and the components that make up the target equipment are represented by a part element. Environmental factors induced by components are linked to the corresponding components through attribute elements; The interface relationships between components are represented by pin elements.

[0028] By implementing step S103 above, this application constructs a natural environment meta-model and an equipment configuration and induced environment meta-model, respectively, using block definition diagrams and internal block diagrams to modularly and standardizedly define the two types of environmental factors. This binary model structure not only supports the rapid retrieval and combination of environmental factors, but also allows for agile iterative updates of the environmental profile during equipment design changes. Through model reuse and parametric expression, the repetitiveness and manual intervention in environmental analysis are significantly reduced, improving the response speed and flexibility in MBSE forward design.

[0029] Step S104: Determine the typical operating environments experienced by the target equipment in different life stages according to the mission of the target equipment; wherein, each life stage includes multiple equipment activities performed in sequence, and each equipment activity corresponds to a typical operating environment, specifically including the following steps S301 to S303. Wherein: Step S301: Determine the typical usage environments experienced by the target equipment in different life stages according to the mission of the target equipment. In this embodiment, the life stages of the target equipment include at least the transportation stage, storage stage, use and maintenance stage, and combat use stage. Taking the combat use stage as an example, the equipment experiences a temporary warehouse environment, a service transportation environment, a combat duty environment, and a combat power-on environment during this stage.

[0030] Step S302: Establish a lifecycle profile and environment association model using use case diagrams. Use case blocks represent each lifecycle stage in the entire equipment lifecycle, and user elements (actors) represent the typical usage environment corresponding to each lifecycle stage, i.e., as shown below. Figure 5 As shown, Figure 5 This is a life profile and environmental correlation model of a certain type of air defense missile, which shows the various life stages in the entire life cycle of the air defense missile.

[0031] Step S303: For each lifecycle stage, an activity diagram is used to construct a typical usage flow description model. Calling behavior activity blocks represent the equipment activities of each lifecycle stage. These equipment activities are then linked sequentially according to their activity sequence, and user-defined latches are used to associate them with the typical usage environment corresponding to each equipment activity. That is, as shown below... Figure 6As shown; it should be noted that equipment activities use the Call Behavior element, which can be directly embedded into the sub-activity diagram for subsequent component-level condition analysis of the activity. The Actor Pin element can represent the typical usage environment corresponding to different equipment activities. By calling the predefined typical usage environment block, the usage environment history of the equipment under the typical usage process can be represented by the access and exit pins.

[0032] By implementing step S104 above, this application models the life profile and mission profile of the equipment using use case diagrams and activity diagrams, and systematically extracts typical usage environments and activity processes in each life phase. This method transforms usage requirements into visual model elements, ensuring that the environmental factors and equipment activities involved in each phase and each mission can be fully captured and correlated, thereby avoiding omissions or inconsistencies that are prone to occur in traditional text descriptions, and effectively improving the comprehensiveness and accuracy of environmental profile analysis.

[0033] Step S105: Construct a typical usage environment factor model based on the typical usage environment and the natural environment meta-model. This typical usage environment factor model is used to characterize the natural environmental factors involved in the target equipment's use in the typical usage environment. Specifically, this includes the following steps S401 to S402. Wherein: Step S401: Determine the natural environmental factors involved in typical usage environments, and represent the natural environmental factors using the environmental attributes defined in the natural environment meta-model; Step S402: Construct the typical usage environment factor model using a block definition diagram, and use allocate relationships to represent the association between the typical usage environment and environmental attributes, such as... Figure 7 As shown, Figure 7 This is a typical environmental factor model for a certain air defense missile in the missile flight environment.

[0034] Step S106: Construct a working condition analysis model based on the equipment activities, equipment configuration, and induced environment meta-model. This working condition analysis model is used to characterize the induced environmental factors caused by the components of the target equipment, specifically including the following steps S501 to S503. Wherein: Step S501: Determine the components of the target equipment based on the equipment configuration and the induced environment meta-model; based on... Figure 4 A typical air defense missile mainly consists of five main components: engine, radar, servo motor, warhead, and outer shell.

[0035] Step S502: Construct a working condition activity model based on the equipment activities and the components of the target equipment. The working condition activity model characterizes the interaction between the components of the target equipment during the equipment activities. Figure 8 As shown, the relevant components of this anti-aircraft missile are described using swimlane notation. The missile's flight activities primarily involve four types of component interaction states, represented by action blocks. After launch, the engine ignites; upon reaching a certain altitude, the radar enters target search mode; after locking onto the target, the servo motor enters attitude adjustment mode, controlling the missile's attitude to approach the target; upon reaching the predetermined distance, the engine shuts down, and the warhead ignites to ultimately destroy the target.

[0036] Step S503: Construct a working condition time sequence model for the target equipment based on the working condition activity model. The working condition time sequence model describes the interaction relationships between components based on the equipment activities defined in the working condition activity model. For example... Figure 9 As shown, the interaction relationships between the components are represented by lifelines. These lifelines determine the induced environmental factors of the components from the equipment configuration and induced environment meta-model. Specifically, the lifeline is mapped from component elements in the equipment configuration and induced environment meta-model, corresponding to the equipment configuration in the model. In the equipment configuration and induced environment meta-model, environmental factors induced by components are linked to the corresponding components through attribute elements. The lifeline determines the induced factors of the equipment components through the mapping relationship, thus determining the range of induced environmental factors of the components associated with this lifeline. Message transmission between components is defined by the component's operating conditions in the operating condition activity model and represented by messages. The switching of a component's own operating conditions is represented by events.

[0037] It should be noted that, in one implementation, MBSE modeling software, such as Rhapsody, provides the function of directly obtaining the operating condition timing model from the operating condition activity model. The correspondence between the elements of each component during the conversion is as described in step S503. The operating condition activity model is used to define the operating condition process of each component of the equipment, while the operating condition timing model is refined based on the defined operating conditions to show the interaction sequence between different components. The synergistic effect of the operating condition activity model and the operating condition timing model is to help users analyze specific inducing environments and refine the types of inducing environments that need to be considered.

[0038] By implementing steps S105 to S106 above, this application uses block definition diagrams, activity diagrams, and timing diagrams to perform detailed modeling of the natural environmental factors and component operating condition transitions and interactions of equipment in specific tasks. This enables precise identification of the natural environment and induced environmental factors involved in each type of activity. This fine-grained analysis method supports layer-by-layer environmental stress tracing from the system level to the component level, ensuring accurate mapping between environmental factors and specific activities and component operating conditions, thereby significantly improving the detail and engineering practicality of environmental analysis.

[0039] Step S107: Generate an environmental profile of the target equipment based on the typical usage environment factor model and the working condition activity model, specifically including the following steps S601 to S604. Wherein: Step S601: Determine the natural environmental factors and induced environmental factors of the target equipment during each equipment activity period based on the typical usage environment factor model and the working condition activity model, and form the life cycle environmental history of the target equipment.

[0040] Step S602: Construct an environmental history matrix view describing the environmental history over the lifespan using a matrix view; such as... Figure 10 As shown, Figure 10 In the matrix, the columns represent the activities of the equipment during the combat phase, the rows represent the environmental attributes defined in the meta-model, and the cells contain the "activity-environment" relationships established through the association (Satisfaction).

[0041] Step S603: Determine the corresponding environmental conditions based on the life-cycle environmental history, associate the environmental conditions with life-cycle activities, and establish an environmental demand parameter description model; the corresponding environmental conditions can be determined based on the determined life-cycle environmental history. Environmental stress can be determined by referring to relevant standards, or environmental stress can be predicted by finite element method, statistical energy method, or extrapolation method. Environmental quantities can also be preliminarily determined using similar equipment data or laboratory data. As shown in Figure 11, as environmental demand parameter description model can be established by associating environmental conditions with life-cycle activities.

[0042] Step S604: Visualize the environmental requirement parameter description model to obtain the environmental profile of the target equipment.

[0043] Based on the environmental parameter description model, it can be visualized in the form of an environmental requirements table, facilitating reading and communication among MBSE stakeholders. It also accurately establishes the correlation between environmental conditions and equipment activities or lifecycle stages. An example of an environmental adaptability requirements table is shown below. Figure 12 As shown, the table comprehensively displays environmental factors, environmental conditions, and equipment activities, demonstrating the correspondence between equipment activities and environmental conditions. Figure 12 The document displays the environmental conditions during missile flight activities. Column 1 lists the ID numbers of all environmental conditions; column 2 displays the overall environmental conditions and their corresponding sub-environmental conditions hierarchically; column 3 shows the indicator requirements for the environmental conditions corresponding to equipment activities; and column 4 shows the equipment activities corresponding to the environmental conditions.

[0044] By implementing step S107 above, this application visualizes and correlates environmental parameters, equipment activities, and environmental factors through matrix views, requirement diagrams, and tabular views, forming a clearly structured and hierarchically distinct model-based environmental profile. This representation not only enhances the readability and traceability of environmental requirements but also facilitates understanding and use by various stakeholders (such as designers, test engineers, and decision-makers), supports cross-disciplinary collaboration and iterative optimization, thereby effectively improving the efficiency of environmental adaptability requirement communication and implementation accuracy.

The MBSE-based environment profile generation system includes a data acquisition unit, a mission element management unit, a meta-model management unit, an environment analysis unit, and an environment profile generation unit. Wherein: A data acquisition unit is used to acquire mission data, which includes the mission of the target equipment and is composed of at least one mission element. The mission element management unit is used to process the mission data based on the Hall triple cone structure analysis method to transform the mission elements into a structured set of elements, which includes a set of equipment components and a set of environments. The meta-model management unit is used to construct a natural environment meta-model of the target equipment based on the environment set; and to construct an equipment configuration and induced environment meta-model of the target equipment based on the equipment component set. An environmental analysis unit is used to determine the typical operating environment experienced by the target equipment in different life stages based on the mission tasks of the target equipment; wherein, each life stage includes multiple equipment activities carried out in sequence according to an activity sequence, and each equipment activity corresponds to a typical operating environment.

The working condition analysis model is used to characterize the induced environmental factors induced by the components of the target equipment.
