斑杂破碎的世界还是系统层次的世 界简

本文对英美科学哲学中的以南茜·卡特赖特为代表的史坦福学派新经验主义提出批评、剖析和讨论,认为南茜否定基本物理定律的普遍性的观点以72_她的“斑杂破碎的世界”是对一般科学方法论和系统科学方法论的一种d颠覆性的论证。清华大学吴彤教授根据新经验主义提出的《破碎的系统观》是我国系统哲学的一种新见解,也是很有启发性和颠覆性的,无论你赞成还是反对,都值得我们认真研究和讨论。本文认为系统科学的发展实际上已经正面解决了“南茜的质疑”。系统科学哲学研究的关键问题在于采取跨学科研究方法,具体地研究不同类型的系统。当今的主攻方向是要研究复杂系统的普遍规律及其突现行为,并用于解决我国开放改革遇到的各种全局性和局域性问题。世界是有系统的和有规律性的而不是班杂~,r4-和无规的。

PERSPECTIVES ON URBAN WATER INFRASTRUCTURE IN CHINA FOR THE 21^ST C0ENTURY： SDMUWEIC MODEL

Based on system dynamics approach, SDMUWEIC model is developed in order to evaluatefuture dynamics of urban water infrastructure development in China. Firstly, this paper presents thebasic structure and characteristics of the model, focusing on water infrastructure‘s dynamicrelationships with population increase, economic development, water resources shortage and waterconservation practices. Secondly, model veracity and robustness tests based on behavior reproductionand uncertainty analyses are illustrated. Thirdly, based on the model, future pattems of China‘s urbanwater infrastructure investment requirements are simulated, and effectiveness of two different policyscenarios are evaluated. Finally, conclusion,; and policy implications are drawn, allowing insights intoChina‘s sustainable water infrastructure policies and managements.

Simulating the supply disruption for the coordinated supply chain

There are many disruptive accidents in the supply chain operations system and achieving the coordination of supply chain is main objective for supply chain research. While disruptive accidents have increasingly influenced the coordinated operation of the supply chain, existing research literature on the supply chain coordination is setting in a stationary environment. The answer for how the disruptive accidents affect the coordinated supply chain is given in this paper. Based on the benchmark supply chain which is coordinated by the negative incentive mechanism, we study the impacts of supply disruption on the supply chain system by using simulation approach in which two different distribution function of random variable are used to express the supply disruption. Comparison between these two simulation results and possible coordination mechanism under the supply disruption are proposed. From the perspective of supply chain risk management, we provide the inspiration for the manager.

Research on web forum oriented rumors spreading and inhibitions北大核心CSCD

A rumor spreading model for the web forum based on the heterogeneity of web forum user behaviors and SEIR model is proposed in this paper. First, according to the mean-field equations of the model on inhomogeneous networks, the critical threshold of the spreading of rumor is deduced, the result of theoretical analysis shows that the increase in trust mechanism between users can effectively inhibit the rumor spread in the network with limited velocity of propagation; Then the simulation and numerical analysis of the model itself and the influences of trust mechanism to the model is given, which verify the validity of the model and the introduction of trust mechanism can effectively reduce the rumor influence, the velocity of rumor spreading and the rumor size; Finally, combined with the previous conclusions and the high-influence limited trust relationships between web forum users, a high-influence immunization strategy is given. The experimental results show that the strategy able to reach better effect than traditional immunization strategy. © 2016, The Journal of Agency of Complex Systems and Complexity Science.

ON INVENTORY STRATEGIES OF ONLINE RETAILERS

1.Introduction This research focuses on online retailers(etailers,hereafter)who engage in the sale of physical goods.In general,the order fulfillment process of such an etailer can be depicted by Figure1.As presented in Figure1,a customer will place an order at the etailer’s website.Upon receipt of each order,the etailer will confirm whether or not stock is available to fulfill the order.Assuming that inventory is indeed available,the order will be packaged,after which it will be delivered …
