Recommender systems aim to suggest the items which can best fit the needs of the users and thus play an important role in online services. To get a satisfactory recommendation, some researchers model the recommendation procedure as a Markov decision process where the recommender is the agent and the users are the environment. Then, they use reinforcement learning to perform the recommendation by sharing the browsing histories of different users. However, when the number of users is large, there will be much noise in the sharing process, limiting the ability of reinforcement learning to generate a satisfactory recommendation. ACP approach is proposed to deal with social computing by learning a parallel system from the real system. There can be less noise in the parallel system than that in the real system with an effective learning process, thus the ACP approach has the potential to address the noise in the recommendation. In this paper, we combine the ACP approach into the reinforcement learning based recommender system to deal with the noise and thus improve the recommendation. Firstly, based on the ACP approach, we train a parallel environment of the real environment. Then we use the trained parallel environment to predict the future state in the Markov decision process of the recommender system. There will be less noise in the predicted states than that in the original states, since the output of our parallel environment is effectively learned by the expectation of the future state in the deep neural network. Finally, instead of the original states, we use the predicted states to generate the recommendation list in the reinforcement learning for the recommendation. In this way, the generated recommendation list can be better with less noise from the states. The theoretical analysis and the experiment illustrate that our recommender system can better perform the recommendation than existing recommender systems.

Fused deposition modelling (FDM) 3D printing, as a supporting technology in social manufacturing and cloud manufacturing, is a rapidly growing technology in the era of industry 4.0. It produces objects with a layer-by-layer material accumulation technique. However, qualitative uncertainties are the common challenges yet. In order to assure print quality, studying the error causing parameters and minimizing their effects are important. This paper presents a feedback-based error compensation strategy, which integrates a fuzzy inference system and a grey wolf optimization algorithm. The objectives are twofold. First, the possible errors in FDM 3D printing are discussed in detail and optimal error causing parameters are obtained in percentage. This is used to understand the effects of the printing errors in every phase of the 3D printing process. From the nine optimization configuration trials used, Config-6 that has 100 number of iterations and 60 wolves is selected due to its higher convergence speed and best fitness value. The integral absolute error (IAE) is used as an objective function and the global minimum is achieved in the iteration interval 86,100\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\left [ {86,100} \right ]$\end{document}. The outputs of this optimization problem are used to achieve the next objective. Second, a closed-loop quality monitoring approach comprising of inner-loops and an outer-loop is taken. The three inner-loops are used to monitor the errors during pre-printing, printing, and post-printing, respectively. The outer-loop, on the other hand, is responsible for monitoring the aggregated errors in all the three 3D printing phases. The error compensation system simulation in Matlab is run for 10 s, and the results show that the “normal” range deformation factors are reached within less than 2 s for the inner-loops, whereas the outer-loop deformation factor is achieved within 2 s. The responses are within the acceptable time range.

Internet business can be divided into two categories: pure online business and Online to Offline (O2O) business. Currently, the recommendation technology for online business is maturing, such as news, movies, products, and so forth. However, traditional recommendation technology can easily cause the overcrowding at some O2O services because of the big data traps. In the end, the users' experience with the O2O service recommendation is useless or very poor because they have to wait for a long time and can't enjoy the service immediately. Hence, how to improve the performance of O2O service recommendation has become a vital problem. To solve the problem, this paper proposes a research framework based on the continuous feedback learning mechanism between cyber layer and social layer. Then, the continuous feedback ideas are implemented in the design of the O2O service recommendation strategy step by step. Furthermore, the computational experiment system is constructed to perform performance analysis of these service strategies. The results show that our research framework is conductive to help O2O service recommendation to escape the big-data traps and to improve user experience.

These three components of ACP can be mapped into three parallel worlds that are called physical, mental and artificial worlds, as shown in Fig. 1. ...

Blockchain, widely known as one of the disruptive technologies emerged in recent years, is experiencing rapid development and has the full potential of revolutionizing the increasingly centralized intelligent transportation systems (ITS) in applications. Blockchain can be utilized to establish a secured, trusted and decentralized autonomous ITS ecosystem, creating better usage of the legacy ITS infrastructure and resources, especially effective for crowdsourcing technology. This paper conducts a preliminary study of Blockchain-based ITS (B 2 ITS). We outline an ITS-oriented, seven-layer conceptual model for blockchain, and on this basis address the key research issues in B 2 ITS. We consider that blockchain is one of the secured and trusted architectures for building the newly developed parallel transportation management systems (PtMS) , and thereby discuss the relationship between B 2 ITS and PtMS. Finally, we present a case study for blockchain-based realtime ride-sharing services. In our viewpoint, B 2 ITS represents the future trend of ITS research and practice, and this paper is aimed at stimulating further effort and providing helpful guidance and reference for future research works.

Intelligent vehicles and advanced driver assistance systems (ADAS) need to have proper awareness of the traffic context as well as the driver status since ADAS share the vehicle control authorities with the human driver. This study provides an overview of the ego-vehicle driver intention inference (DII), which mainly focus on the lane change intention on highways. First, a human intention mechanism is discussed in the beginning to gain an overall understanding of the driver intention. Next, the ego-vehicle driver intention is classified into different categories based on various criteria. A complete DII system can be separated into different modules, which consists of traffic context awareness, driver states monitoring, and the vehicle dynamic measurement module. The relationship between these modules and the corresponding impacts on the DII are analyzed. Then, the lane change intention inference (LCII) system is reviewed from the perspective of input signals, algorithms, and evaluation. Finally, future concerns and emerging trends in this area are highlighted.
... The main reasons are as follows: 1) the model built in normal situations is no longer suitable for the simulations of crowd evacuation in the disasters; 2) it makes the controlled experiments not feasible for data collection because of moral and ethical considerations, and the field observations become much more difficult than that in normal situations; and 3) the behaviors and characteristics of pedestrian flows are much more complex and unpredictable in a disaster situations, especially in a state of panic. The parallel system theory was proposed for complex system control and management based on the artificial systems, computational experiments, and parallel execution approach [63]- [65], [65], which provides a promising way to get out this dilemma. It was used to explore crowd evacuation behaviors and evaluate evacuation strategies in the case of fire at the subway station and high-rise building [66], [67]. ...

The statistic analyses of most productive authors, institutions, countries/regions, and cited papers, as well as keywords and their trends, are conducted based on the data set collected from the Web of Science. The most productive and high-impact authors, institutions, and countries are identified. The results of bibliographic analyses show that Europe researchers dominate and guide the research of PED in that it not only has the most papers but also has six out of the ten most-cited papers. Helbing Dirk is an influential author in the research of PED field in that he has five out of the ten most-cited papers. Chinese institutions account for 70% of the top 10 most productive institution and three among the top 5 ranks. Meanwhile, researchers from China and USA have published nearly half of the papers in this field. In addition, we generate four networks, i.e., coauthorship network, coinstitution network, cocountry/region network, and document cocitation network to analyze collaboration patterns and evolution of PED research at different levels. The software of Citespace is adopted to visualize the topological interactions among authors, institutions, and countries/regions as well as document cocitations. The degree, betweenness, burst, and PageRank are selected and measured as indicators to identify the key nodes. Finally, some future directions are put forward. The results of this paper provide a better understanding of patterns, trends, and other important factors as a basis for directing research activities, sharing knowledge, and collaborating in the field of PED research.

The complexity science, with the help of, agent based modeling has recently claimed that the free market economy is producing wealth inequality—a totally opposite perception, which is in practice for more than 10 decades. It is capable of investigating the distribution of money in the market economy and finding solution for unfair gap between the wealth and, thus, overcoming poverty. This paper is an attempt to investigate this claim. This work is inspired from Gooding’s work and it, therefore, reproduces his toy trader model, which claims to offer a fair trading environment. This model is extended towards a more human-oriented economy by introducing two possible biases: the variation of market visibility between the traders (by introducing the social networks of traders) and monopoly. The basic aim was to find out the impact of market visibility and monopoly on wealth distribution and poverty. It was learnt through simulations performed, in NetLogo, that the accessibility of traders, when taken as an important factor of a free market economy, positively influences wealth disparity, wealth gap and controls poverty. However, more human-oriented economy, in fact, widens the rich-poor divide and increases poverty. These results suggest that the authorities must control the market and everyone involved in trading should be given equal opportunities. This would also help in controlling the possible monopoly of the traders. The intrinsic physics of the free market would, otherwise, will always result in an unequal distribution of wealth.

The outbreak of unconventional emergencies leads to a surge in demand for emergency supplies. How to effectively arrange emergency production processes and improve production efficiency is significant. The emergency manufacturing systems are typically complex systems, which are difficult to be analyzed by using physical experiments. Based on the theory of Random Service System (RSS) and Parallel Emergency Management System (PeMS), a parallel simulation and optimization framework of production processes for surging demand of emergency supplies is constructed. Under this novel framework, an artificial system model paralleling with the real scenarios is established and optimized by the parallel implementation processes. Furthermore, a concrete example of mask shortage, which occurred at Huoshenshan Hospital in the COVID-19 pandemic, verifies the feasibility of this method.

As a complex and critical cyber-physical system ( CPS ), the hybrid electric powertrain is significant to mitigate air pollution and improve fuel economy. Energy management strategy ( EMS ) is playing a key role to improve the energy efficiency of this CPS. This paper presents a novel bidirectional long short-term memory ( LSTM ) network based parallel reinforcement learning ( PRL ) approach to construct EMS for a hybrid tracked vehicle ( HTV ). This method contains two levels. The high-level establishes a parallel system first, which includes a real powertrain system and an artificial system. Then, the synthesized data from this parallel system is trained by a bidirectional LSTM network. The lower-level determines the optimal EMS using the trained action state function in the model-free reinforcement learning ( RL ) framework. PRL is a fully data-driven and learning- enabled approach that does not depend on any prediction and predefined rules. Finally, real vehicle testing is implemented and relevant experiment data is collected and calibrated. Experimental results validate that the proposed EMS can achieve considerable energy efficiency improvement by comparing with the conventional RL approach and deep RL.

Energy internet (EI) is a complex coupled multienergy system; it is essential to investigate its multienergy dispatching optimization issues. To this end, this paper first proposes a novel conception of smart dispatching for EI with a complex cyber‐physical‐social system (CPSS) network from the perspective of parallel dispatch, called parallel dispatching robot (PDR), and investigates the implementations of PDR based on smart artificial society (SAS) modeling. First, we introduce EI and describe the dispatching issues of EI. Second, we discuss several important concepts supporting the parallel dispatch conception of EI, including knowledge automation (KA), CPSS, and parallel machine learning (PML). On the basis of these, we elaborate the concept of parallel dispatch. Moreover, we construct a large closed‐loop feedback control framework of parallel dispatch for EI integrating a CPSS network based on KA and PML. Third, we establish an experimental platform for PDR research based on the proposed parallel dispatch framework. Fourth, we develop the PML‐based SAS models of a single PDR in centralized dispatching modes and group PDRs in decentralized dispatching modes to achieve crowd wisdom emergence and performance improvement in current cyber‐physical system frameworks of EI. Moreover, we design an external global closed loop for PDR to evaluate its operation stability. Lastly, we conduct a detailed discussion on PDR and offer some prospects for its engineering implementations. The biggest innovation of this paper lies in systematically proposing the smart dispatching concept and framework for complex CPSS‐based EI from the perspective of parallel dispatch and thoroughly investigating how to use SAS modeling to implement parallel dispatching and control for EI considering human and social factors, which is a major extension and theoretical improvement to existing single smart wide area robot concept and a preliminary attempt in investigating a shift from Energy 4.0 to Energy 5.0 in China. We first systematically propose a novel smart dispatching framework for energy internet with complex cyber‐physical‐social systems from the perspective of parallel dispatch, called parallel CPSS framework. This framework is developed for the parallel dispatching of multienergy coupled energy internet with a complex CPSS structure represented by a new generation of energy and electric power systems. In this framework, the proposed parallel dispatching robots are employed to simulate human dispatcher group considering human and social factors (eg, the energy markets).

In recent years, the rapid development of block chain technology has spawned the emergence of the so-called decentralized autonomous organization (DAO), which is a new organization form that the management and operational rules are typically encoded on block chain in the form of smart contracts, and can autonomously operate without centralized control or third-party intervention. Therefore, DAO is expected to become a new and effective organization to deal with uncertain, diverse and complex environments. Defining the conception and features is the first priority. Furthermore , the five layer structural model of DAO analyzing frame to analyze typical Aragon model was proposed and the current issues as well as the research direction in future were discussed, hoping to provide significant guidance and reference for following researchers.

As a new FinTech innovation regulation tool, regulatory sandbox effectively balances financial innovation and risk, so it is adopted by many regulatory authorities around the world. However, until now, regulatory sandbox is still at the stage of manually submitting data, and artificial intelligence has not been applied to it. Hence, in this paper, we propose the framework of Parallel FinTech Regulatory Sandbox based on the ACP approach (Artificial systems + Computational experiments + Parallel execution). Then, we talk about how to combine the emerging blockchain technology with intelligent regulatory sandbox, thus solving problems such as poor data flow and regulation sluggish. This paper is aimed at providing helpful guidance and reference for the development of FinTech regulatory sandbox.

This will not only save new tenants’ decoration costs, but also improve equipment maintenance efficiency and quality. The combination of BT and BIM technology will bring about a number of changes in project management technology in the construction industry and improve the overall technical level of the industry.

In 2017, I offered my resignation from the BoG in order to be the EiC of TCSS, and now I need to resign my EiC position since I have been elected as SMCS’s VP in the end of 2019. Thank you all for this extremely valuable three-and-half year experience in a field I truly love and enjoy, but it is time to let new leadership to lead TCSS to a new level of quality and excellence. A call for new EiC was announced by VP for Publication at the end of May, and I am happy to inform you that, by the deadline of June 10, seven scholars from North America, Europe, and Asia have been recommended for the EiC position. A decision will be made by the Selection Committee in July and I will announce the result in the next issue.

The concept, basic framework, methodology and applications of parallel city were presented in this paper. The parallel city is an application of ACP-based parallel intelligence in city fields. The real city is running with its equivalent, and the artificial city is in virtual space, in a parallel and interactive way. The artificial city has the descriptive, predictive, and prescriptive functions on the real city. There is a closed-loop workflow between the real city and the artificial city, which iteratively optimizes the urban systems, leading to a new paradigm of intelligent urban management.

As a new form of manufacturing industry in cloud environment, social manufacturing has its inherent “social–cyber” complexity: the source of enterprise services is social, and this sociality aggravates the diversity, uncertainty and dynamics of service supply. Researchers have done a lot to improve the adaptability of service matching strategies. However, it is difficult or even impossible to for traditional methods to evaluate the viability of these strategies because of the “social–cyber” complexity. This poses new challenges to how to evaluate and optimize these strategies in a complex social manufacturing environment. Aiming at the problem, this paper proposes a computational experiment-based evaluation framework, which can simulate all kinds of actual scenarios to verify the performance of service matching strategies. This method includes three parts: (1) design of supply & demand matching strategy; (2) construction of computational experiment system; (3) performance evaluation of service strategies in different experiment environments. A case study is given to verify the applicability of our method by means of comparing several adaptive service matching strategies (supply-oriented, demand-oriented, initial supply & demand-oriented, optimized supply & demand-oriented) in two kinds of market environments. The results demonstrate that our method has a substantial promise.
