  • 简介:复杂适应系统(cas)-包含当他们交往,适应或学习的许多部件的系统-在重要当代的问题的心。学习ofcas提出唯一的挑战:一些我们的很强大的数学工具,特别地,包含的方法修理了点,引起注意的人,等等,具有在理解cas的发展的有限帮助。这篇论文建议方法修改研究方法和工具,与基于计算机的模型的角色上的一个重音,到增加我们cas的理解。

  • 简介:纸建议帮助在量的术语调查真实网络的竞争方面的一个模型。通过理论分析和数字模拟,它证明竞争模型为一个加权的网络有普遍性。在在加权的网络的参数和在竞争网络的竞争力之间的关系被理论分析获得。基于竞争网络,力量和度的度分发的表达式加权的网络的分布能被计算。分析解决方案表明加权的网络的度分发与增长和边重量的起始的价值被相关,它被数字模拟验证。而且,与象一个网络,一个更新的系数,起始的重量和竞争力的尺寸那样的网络参数一起的一个聚类的系数的演变模式被进一步的模拟获得。

  • 简介:服务性行业在工业化国家采用工人的一个大、成长的比例,并且它逐渐地依赖于信息和通讯技术。当生产和服务的互相依赖,类似和补充是重要的时,商品和服务之间有可观的差别,包括在到集体定制的从大量生产的焦点的移动(一种服务由此响应一个顾客被生产并且交付,说了或把归咎于需要)。一般来说,服务能被认为是作为供应商一起工作的知识集中的代理人或部件,创造的消费者或共同生产珍视。象生产系统一样,一个有效服务系统一定是系统的一个综合系统,导致更大的连接和互相依赖。集成必须在物理、时间、组织上、功能的尺寸上发生,并且必须包括担心部件,管理,和系统的方法。而且,一个有效服务系统一定也是一个能适应的系统,导致更大的价值和应答的海角。改编必须发生在监视的尺寸上,反馈,控制论并且学习,并且必须包括担心空间,时间,和系统的方法。简言之,服务系统是确实复杂的,特别由于与如此的系统的以人为中心的方面联系的不确定性。而且,系统复杂性能仅仅被处理提高系统集成和改编的方法。纸与几卓见得出结论,包括转移开发为为进一步开发服务的一条系统工程途径的服务的一门科学或学科的当前的错放的焦点的一个请求,一条途径基于集成和改编大量科学或学科(例如,物理,数学,统计,心理学,社会学,等等)。事实上,被要求的,是服务相关的transdisciplinary-远非一个单身者所及纪律-本体论或分类作为纪律集成和改编的一个基础。
