A calculus for services innovation 总被引:1,自引:1,他引:0
Innovation in the services area - especially in the electronic services (e-services) domain - can be systematically developed by first considering the strategic drivers and foci, then the tactical principles and enablers, and finally the operational decision attributes, all of which constitute a process or calculus of services innovation. More specifically, there are four customer drivers (i.e., collaboration, customization, integration and adaptation), three business foci (i.e., creation-focused, solution-focused and competition-focused), six business principles (i.e., reconstruct market boundaries, focus on the big picture not numbers, reach beyond existing demand, get strategic sequence right, overcome organizational hurdles and build execution into strategy), eight technical enablers (i.e., software algorithms, automation, telecommunication, collaboration, standardization, customization, organization, and globalization), and six attributes of decision informatics (i.e., decision-driven, information-based, real-time, continuously-adaptive, customer-centric and computationally-intensive). It should be noted that the four customer drivers are all directed at empowering the individual - that is, at recognizing that the individual can, respectively, contribute in a collaborative situation, receive customized or personalized attention, access an integrated system or process, and obtain adaptive real-time or just-in-time input. The developed process or calculus serves to identify the potential white spaces or blue oceans for innovation. In addition to expanding on current innovations in services and related experiences, white spaces are identified for possible future innovations; they include those that can mitigate the unforeseen consequences or abuses of earlier innovations, safeguard our rights to privacy, protect us from the always-on, interconnected world, provide us with an authoritative search engine, and generate a GDP metric that can adequately measure the growing knowledge economy, 相似文献

1. Introduction Benchmarking delivers a “comparison of a company’s performance in certain areas with that of other firms in its industry and / or with those firms that are identified as world class competition in specific functions and operations” (Davis et al, (2004). It can also cut across traditional lines, providing opportunities for new and innovative ways to increase performance, and be a “search for industry best practices that lead to superior performance” (Camp, 1989; Hinton et … 相似文献

HEALTHCARE: A COMPLEX SERVICE SYSTEM 总被引:5,自引:3,他引:2
Healthcare is indeed a complex service system, one requiring the technobiology approach of systems engineering to underpin
its development as an integrated and adaptive system. In general, healthcare services are carried out with knowledge-intensive
agents or components which work together as providers and consumers to create or co-produce value. Indeed, the engineering
design of a healthcare system must recognize the fact that it is actually a complex integration of human-centered activities
that is increasingly dependent on information technology and knowledge. Like any service system, healthcare can be considered
to be a combination or recombination of three essential components — people (characterized by behaviors, values, knowledge,
etc.), processes (characterized by collaboration, customization, etc.) and products (characterized by software, hardware,
infrastructures, etc.). Thus, a healthcare system is an integrated and adaptive set of people, processes and products. It
is, in essence, a system of systems which objectives are to enhance its efficiency (leading to greater interdependency) and
effectiveness (leading to improved health). Integration occurs over the physical, temporal, organizational and functional
dimensions, while adaptation occurs over the monitoring, feedback, cybernetic and learning dimensions. In sum, such service
systems as healthcare are indeed complex, especially due to the uncertainties associated with the human-centered aspects of
these systems. Moreover, the system complexities can only be dealt with methods that enhance system integration and adaptation. 相似文献

战争决策行为建模与仿真的研究 总被引:4,自引:2,他引:2
目前,世界上局部战争和国际危机此起彼伏,因此,运用科学的手段和方法,展开针对可能引发军事冲突或爆发战争的危机的决策行为的研究,具有重大的现实意义。它有助于揭示战争危机的内在规律,使得危机朝着我们期望的方向发展。本文以美国为研究对象,全面阐述了影响个人决策、组织决策和群体决策的非理性行为约束变量,深入研究了美国战争危机的决策机构,分析了其决策过程。以此为基础,采用新的建模与仿真技术-agent技术,探讨了个人决策、组织决策和群体决策的agent技术建模机制,建立了基于Agent技术的战争决策行为模型体系结构,并根据编程实践,ZEUS和MAGE两种agent开发系统正确比较的基础上,给出了在两种开发系统下实现战争决策行为模型的编程构想。它为分析美国战争危机决策提供了理论和方法上的指导,具有很强的实践意义和现实意义。 相似文献

Modern modes of transport, in the developed world, were designed to achieve higher mobility (or speed) and increased accessibility, all in the name of growth and human progress. However, in the course of providing for this higher mobility, through the rapid expansion of the transport system, we have ended up with a condition of imbalanced mobility, which we refer to as "hypermobility," particularly with reference to the automobile mode. Ironically, this very expansion of the transport network, with the objective of providing higher transport speeds, has resulted in traffic congestion that has drastically reduced mobility and accessibility, thereby lowering business productivity, increasing fuel consumption, increasing pollution, and robbing the public of billions of hours of valuable time. In light of the present unsustainable conditions, we examine and analyze the concepts of mobility through an inquiry of time, space, human freedom, and social justice from an ethical and systemic viewpoint. We conclude that if hypermobility is not dealt with both as an individual and as a collective responsibility, the challenge to transport ethics and its systemicity could be further impaired. 相似文献
