Fworst and fbest denote the worst and best fitness of the initial swarm, respectively. The term fit indicates the fitness of the i-th particle at the t-th iteration. The randomness of initial particle positions in PSO leads to significant differences between the initial best and worst fitness values.

The model will then be used to estimate risks including elements such as mean time before failure, reliability, cost, probability of success, etc. Iterations will be made to the design model and key risks annotated so they can be solved before moving on to the next stage of development. This is important to ensure that the system is getting closer to meeting the user problems and requirements and if not, the appropriate changes are made while the cost to change is still low. As systems began to increase in function and complexity, this method of development became untenable.

Those needs are then translated into specific, measurable system requirements. MBSE tools and data modeling allow for the creation of a detailed model that captures these requirements, so that they are consistent and aligned with the overall objectives. Through system architecture design, the overall structure of the system is developed. The process of model-based systems engineering is a series of interconnected phases that guide system development from concept to completion. Modeling and simulation are valuable for testing conditions that are difficult to reproduce with hardware prototypes alone. This is especially true in the early phase of the design process when hardware is not yet available.

Model-based systems engineering

At each stage of the process, models of appropriate abstraction for that phase are used to represent system components and to simulate the design. These models can initially be high abstraction, modeling macro behavior for the purpose of general concept and conceptual architecture exploration. For an improved design of the microstructure in context to the targeted property, it is essential to understand the correlation between the physical descriptors describing the microstructure and the property. Figure 2a illustrates the segmented 3D microstructure for sample HPA, HPB and NPC, utilizing the U-net model based on the semi-automatic hybrid annotation. Here, exemplary the segmented volume of interest (VOI) for 175 °C is shown. The microstructure exhibits significant differences for the three materials HPA, HPB and NPC.

The results provide guidelines for the microstructure design, uncovering the most critical microstructural features for the electrical conductivity. During the process of selecting representative monitoring stations, we employed a greedy algorithm to ensure comprehensive coverage of the study area by the chosen sites. Given the central location of the Olympic Center in Beijing, we designated it as the initial representative station. Subsequently, we iteratively selected stations that were geographically furthest from the existing set until we obtained the required number of representative sites. This method aims to maximize the spatial distribution distance between representative sites. It ensures a broad and balanced coverage of air quality conditions across different areas of Beijing.

Its emphasis on holistic and integrated systems thinking helps in developing solutions that are not only technically sound but also environmentally responsible. Major automotive companies like Ford and BMW have incorporated MBSE in designing their vehicles. This approach helps in managing the increasing complexity of modern cars, which include advanced electronics and software. Extend models to systems in operation to perform predictive maintenance and fault analysis. When the MIL simulation results meets all the system requirements, then the development moves onto the next stage. The main benefit of automatic code gen is that with every model change, the code can be automatically updated and instantly deployed to the hardware.

For HPA and HPB, the confidence interval lies within 2.4–36.4 nm and 0.7–23.6 nm, respectively, and is significantly larger than for the NPC material. To evaluate the performance and generalization ability of our proposed model, we meticulously processed the experimental datasets. This ensures an increase in data scale for a thorough examination of the model's potential advantages for handling datasets of varying sizes. Based on the CUDA programming platform, this paper implements the SVR algorithm by using the CPU-GPU heterogeneous parallel method and mainly uses two parallel strategies, vectorization, and parallel protocol. In numerical optimization problems, many operations can be represented as vectors. By implementing vectorization operations in the GPU, reading multiple operands at once and performing the same operation on all operands at the same time can greatly reduce the time to complete vector operations.

Using the AWS Well-Architected Tool, available at no charge in the AWS Management Console, you can review your workloads against these best practices by answering a set of questions for each pillar. Model-Based Definition is undeniably an exciting advancement in the field of engineering. With its ability to enhance collaboration, unleash innovation, and redefine design and manufacturing processes, MBD is paving the way for a more efficient and effective engineering industry. Ongoing collaboration, regular reviews, and continuous improvement are crucial to refine and optimize the MBD implementation. By embracing MBD as a company-wide initiative and fostering a culture of innovation and collaboration, companies can successfully transition to a more efficient, accurate, and streamlined approach to product development. To begin implementing MBD in a successful way, you must clearly define their objectives and identify the specific benefits they aim to achieve with MBD, such as improved communication, reduced errors, and streamlined workflows.

These early programmable logic controllers (PLC) mimicked the operations of already available discrete control technologies that used the out-dated relay ladders. The advent of PC technology brought a drastic shift in the process and discrete control market. An off-the-shelf desktop loaded with adequate hardware and software can run an entire process unit, and execute complex and established PID algorithms or work as a Distributed Control System (DCS).

The smaller the C and the smaller the error loss on the model, which result in a decrease in the accuracy of training the SVR model. The larger C and the greater the penalty for error and the likelihood of overfitting the model. When σ → 0, the decision function of the support vector machine will be close to a constant, which results in lower regression accuracy for both the training and prediction samples.

LIBSVM is optimally accelerated for early single-core CPUs and provides limited parallelization support. However, with the dramatic increase in the amount of raw data and problem size, the training and prediction speed of LIBSVM is often insufficient to meet the actual algorithm debugging and application needs. This Guidance shows how you can streamline and accelerate product development by building an MBDE for engineering and design. Using AWS as the foundation, you can create a modern cloud computing platform that is more secure, agile, and lightweight than on-premises document-based engineering environments. You can also use MBDE-generated models and data to build advanced analytics and generative models for predicting system behavior.

In particular, the U-Net architecture28 is considered as a highly valuable approach for most image segmentation workflows25,26,29. However, further improvement of the prediction accuracy is mandatory for accelerated material design. Yet, the prediction accuracy not only relies on the model architecture but also concerns the efficiency of the annotation process. Usually the annotation of the present phases within the microstructure is performed manually30. However, this is time-consuming especially for a large amount of data as well as heavily relies on user expertise. The need for rapid annotation for tomographic image data enabling an enhanced prediction accuracy beyond the state of the art is crucial rather than a supplement.

Our research incorporates this difference into the calculation formula, effectively differentiating the inertia weights of particles with varying fitness levels. This enhances the global search capability in the early stages of the algorithm. As fitness improves, the inertia weight of particles decreases, slowing their velocity to facilitate meticulous local search and prevent overshooting the optimal solution. In PSO, the setting of the inertia weight is crucial for the search capability. A larger inertia weight promotes global exploration, while a smaller one favors local exploitation.

Under this framework, SVR, with its lower complexity, limited parameter count, and simplified tuning process, demonstrates a significant acceleration advantage when handling large datasets and remains effective on smaller ones. Compared to deep neural networks, SVR does not require extensive datasets to prevent overfitting nor excessive time and resources for training. It is better suited for structured meteorological data, and the heterogeneous parallel architecture further enhances its computational efficiency and resource conservation in haze pollution prediction. However, the performance of SVR is heavily contingent upon parameter optimization. Population intelligence algorithms have emerged as a response to the computational demands and data quality requirements inherent in complex problem-solving. These algorithms offer a novel computational framework that is robust to hyperparameter selection, effectively navigating the challenges presented.

Like most organizations, public or private, Hiller Measurements is driven to produce more value, faster and leaner than ever before, while improving overall quality. For many, the answer seems to be “you can’t,” which becomes the assumed reality until a single organization proves otherwise. A detailed guide is provided to experiment and use within your AWS account. Each stage of building the Guidance, including deployment, usage, and cleanup, is examined to prepare it for deployment.

Now that I have described the basics of a model's language and domains, I will describe the modeling approach. A model must describe both a problem that the designed system solves, and the designed system itself (the solution). The model must have these two sides, the problem side and the solution side. These are sometimes referred to as the operational and system points of view. Anyone who is about to start modeling must realize that a set of views is not a model.
