This paper analyzes the doing-business environment (DBE) at prefecture-level city in China. Based on the input-process-output (IPO) thought of system theory, this study uses Porter Diamond Model and International Institute for Management Development (IMD) regional competitiveness model to construct the China City Doing-business Environment Index (CCDBEI) from five aspects: Factor Supply Index (FSI), Environmental Attraction Index (EAI), Demand Pull Index (DPI), Industrial Security Index (ISI) and Output Influence Index (OII). The weight of single index was calculated by entropy method, and the DBE quality of 289 prefecture-level cities in China was evaluated by correlation coefficient method on the basis of considering the logical relationship of secondary indexes. The evaluation results show that the overall quality of DBE in China is gradually improving, but the regional differences are significant, and the best region was always East China, the worst were in the Northwest and Northeast. Location analysis shows that the quality of DBE is closely related to regional development strategy. Furthermore, the advantages of DBE in different regions are also different. In addition, it is found that DBE quality and balance do not develop synchronously. The study provides guidance for further optimization of DBE in cities.
本文对中国地级市的营商环境进行了分析。本文基于系统理论的投入-过程-产出(IPO)思想,运用波特钻石模型和国际管理发展研究所(IMD)区域竞争力模型,从要素供给指数(FSI)、环境吸引力指数(EAI)、需求拉动指数(DPI)、产业安全指数(ISI)和产出影响指数(OII)五个方面构建了中国城市营商环境指数(CCDBEI)。采用熵值法计算单项指标权重,在考虑二级指标逻辑关系的基础上,采用相关系数法对289个地级市的DBE质量进行评价。评价结果表明,中国DBE的整体质量在逐步提高,但区域差异显著,最好的地区始终是华东地区,最差的地区是西北和东北地区。区位分析表明,DBE的质量与区域发展战略密切相关。此外,DBE在不同地区的优势也不同。此外,还发现DBE质量和平衡性并不是同步发展的。该研究为城市DBE的进一步优化提供了指导。

Mobile crowdsensing (MCS) uses participants' computing resources to collect and analyze data and it has been applied in several areas to bring the convenience to people's lives. In MCS, the minimization of travel distance with location privacy is a common objective but should not be the only one practically. Different from the single objective of travel distance minimization, in this paper we formulate a multi-objective optimization model based on bit flipping mechanism, i.e., travel distance minimization and sensing quality score maximization, which is more suitable for a practical scenario. In order to solve the large-scale optimization problem, a Multi-Objective Simulated Annealing approach (MOSA) is utilized to derive a Pareto solution for decision makers. Extensive simulation results illustrate the feasibility and effectiveness of the proposed scheme.
移动众测(MCS)利用参与者的计算资源来收集和分析数据,并已应用于多个领域,为人们的生活带来便利。在MCS中,在保证位置隐私的情况下最小化旅行距离是一个共同的目标,但实际上不应该是唯一的目标。与单目标的行程距离最小化不同,本文建立了基于位翻转机制的多目标优化模型,即行程距离最小化和传感质量分数最大化,更适合于实际场景。为了解决大规模优化问题,利用多目标模拟退火方法(MOSA)推导出决策者的Pareto解。大量的仿真结果验证了该方案的可行性和有效性。

Secondly, the complex multi-component cooling load signal is decomposed into multiple single-component amplitudes and frequency modulation (AFM) signals by VMD. The PE is used to quantitatively determine the noise content of each component after VMD decomposition, the high noise component is directly removed, the low noise component is smoothly processed by the SG smoothing method, then, the signal is reconstructed. Finally, the TCN model of air-conditioning cooling load prediction is established. The experimental results show that the prediction accuracy of the hybrid model is significantly improved compared with the conventional models.

The efficient operation of the cooling source system depends on a reasonable control strategy, and accurate cooling load prediction provides important guidance for optimal control. As there are numerous variables that affect the prediction of cooling loads, many cooling load prediction methods try to exploit the variables in the temporal domain. However, the correlations between the variables are not reasonably utilized by many methods. To exploit the implicit information of the data and obtain an accurate cooling load prediction, the correlative temporal graph convolutional network (CTGCN) is used to predict the cooling load, which can extracted the correlation information and the temporal information. Notably, the correlations between the key variables that affect the cooling load prediction are used for the correlation graph construction, which provides guidance for correlation information extraction. Some traditional prediction methods are compared to prove the effectiveness of the proposed method in the field of cooling load prediction. The results show that the proposed model has great practical value in cooling load prediction.
冷源系统的高效运行依赖于合理的控制策略,准确的冷负荷预测对优化控制具有重要指导意义。由于影响冷负荷预测的变量众多,许多冷负荷预测方法都试图在时域中利用这些变量。然而,许多方法并没有合理地利用变量之间的相关性。为了挖掘数据的隐含信息,获得准确的冷负荷预测,采用相关时间图卷积网络(CTGCN)进行冷负荷预测,该网络可以提取相关信息和时间信息。值得注意的是,将影响冷负荷预测的关键变量之间的相关性用于关联图的构建,为关联信息的提取提供了指导。通过对几种传统预测方法的比较,验证了该方法在冷负荷预测领域的有效性。结果表明,该模型在冷负荷预测中具有重要的实用价值。

The output feedback tracking control problem for a class of a one-link manipulator with full state constraints is investigated. Firstly, a fuzzy state observer is constructed for estimating the unmeasurable states. Then, by fusion of the new state transformation function and the dynamic surface control method, an observer-based adaptive fuzzy control strategy is established. Moreover, it is proved that the signals in the control systems are bound and the states of systems are never transcended the constraints by using the Lyapunov stability theory.

Sparse Causality Analysis Approach with Time-varying Parameters for Root Cause Localization of Nonstationary Process 非平稳过程根源定位的时变参数稀疏因果分析方法

Root cause diagnosis (RCD) is an important technique for maintaining the safe operation of industrial processes. Traditional RCD methods usually require stationarity assumptions. However, the process inevitably shows nonstationarity due to factors such as switching of operating conditions. Although there have been some previous studies trying to overcome the challenge of nonstationarity, these methods fail to guarantee the significance of the extracted causalities and lead to redundant relationships. To address the above issues, a sparse causal analysis model with time-varying parameters is extracted in this study. First, we propose an end-to-end information fusion and prediction task to characterize predictive relationships between variables and avoid repeated modeling. Second, we design time-varying parameters for the information fusion mechanism to cope with nonstationarity and automatically identify significant causality through sparse parameter updates. We design an update strategy that constrains the gradient information to guarantee sparsity. Finally, a causal metric is constructed for the time-varying predictive relationship to comprehensively obtain the overall causal relationship, which further guarantees causal significance. The validity of the proposed method is illustrated through a real industrial example collected from a thermal power plant.
根本原因诊断(RCD)是维持工业过程安全运行的一项重要技术。传统的RCD方法通常需要平稳性假设。但由于工况的切换等因素,过程不可避免地呈现出非平稳性。虽然以前有一些研究试图克服非平稳性的挑战,但这些方法不能保证提取的因果关系的显著性,并导致冗余关系。针对上述问题,本研究提取了一个参数时变的稀疏因果分析模型。首先,我们提出了一个端到端的信息融合和预测任务,以表征变量之间的预测关系,避免重复建模。其次,为信息融合机制设计时变参数,以应对非平稳性,并通过稀疏参数更新自动识别显著因果关系。我们设计了一种约束梯度信息的更新策略以保证稀疏性。最后,对时变预测关系构建因果度量,全面获得整体因果关系,进一步保证因果显著性。通过某火电厂的实际工业实例,验证了该方法的有效性。

In this paper, we develop an event-driven robust guaranteed cost control strategy of continuous-time (CT) systems via improved adaptive critic learning (ACL). First, we choose a suitable cost function which reflects uncertainties, control, and regulation, in order to transform the robust control problem into the optimal control problem. Then, we obtain the time-driven optimal control law and the Hamilton-Jacobi-Bellman equation. Next, through theoretical analysis, we derive the event-driven optimal control law of the nominal system based on the ACL method, and prove the robust stabilization of the CT nonlinear system. Additionally, we construct a novel critic neural network learning algorithm to accelerate the convergence of weights. We also obtain the neural-network-based event-driven condition and prove the closed-loop system stability. Finally, the simulation result shows the effectiveness of the event-driven guaranteed cost control design.

Finally, the simulation result shows the effectiveness of the event-driven guaranteed cost control design.","PeriodicalId":138951,"journal":{"name":"2022 4th International Conference on Industrial Artificial Intelligence (IAI)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131511246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a hybrid classification method for image based anomaly detection is proposed to improve the detection rate from industrial high-dimensional process data. The method involves feature selection with clustering based classification to discover failure patterns for marginal datasets to improve detection accuracy. The proposed hybrid classification method is tested with a real industry data sets. Results show that the proposed hybrid classification method is superior to the conventional classification methods such as multilayer perceptron (MLP) and decision tree in term of anomaly detection accuracy.
为了提高工业高维过程数据的异常检测率,提出了一种基于图像的混合分类方法。该方法通过特征选择和基于聚类的分类来发现边缘数据集的故障模式,以提高检测精度。用实际工业数据集对所提出的混合分类方法进行了验证。结果表明,该方法在异常检测精度方面优于传统的多层感知器(MLP)和决策树等分类方法。
