广州数字化从市政开始

广州市政园林局主管全市市政、供水、燃气和城市园林管理，同时还肩负着对城市道路、排水、污水集中处理、绿化、自来水和燃气的管理工作。面对如此多的管理部门，“广州数字市政”的负责人、广州市政园林局程朴博士说，要提高管理、建设、运营水平和效率．广州就必须建设一个统一的信息系统平台．并且要在这个平台上共享各种信息．以便管理不同领域的公用基础设施。根据规划，广州的“数字城市”建设从与市民最贴切的市政数字化开始。

Gamifying collective human behavior with gameful digital rhetoric

This paper presents a design framework called Gameful Digital Rhetoric that offers a set of design frames for designing meaningful digital rhetoric that guides collective human behavior in ubiquitous social digital services, such as crowdsourcing. The framework is extracted from our experiences with building and developing crowdsourcing case studies. From a video game perspective, the paper has categorized our experiences into seven design frames to encourage collective human activity. This approach is different from traditional gamification, as it focuses more on the semiotic aspect of virtuality in the video games, not game mechanics; it helps to enhance the current meaning of the real world for changing human attitude and behavior through various socio-cultural and psychological techniques. Therefore, it is possible to discuss respective design frames for enhancing crowdsourcing by incrementally adding new digital rhetoric. The paper also presents how Gameful Digital Rhetoric allows us to guide collective human behavior in Collectivist Crowdsourcing; the design is explained through a scenario-based and experiment-based analyses. The paper then discusses how to design collective human behavior with Gameful Digital Rhetoric and how to identify the design’s potential pitfalls. Our approach offers useful insights into the design of future social digital services that influence collective human behavior

Design of emerging digital services: a taxonomy

There has been a gigantic shift from a product based economy to one based on services, specifically digital services. From every indication it is likely to be more than a passing fad and the changes these emerging digital services represent will continue to transform commerce and have yet to reach market saturation. Digital services are being designed for and offered to users, yet very little is known about the design process that goes behind these developments. Is there a science behind designing digital services? By examining 12 leading digital services, we have developed a design taxonomy to be able to classify and contrast digital services. What emerged in the taxonomy were two broad dimensions; a set of fundamental design objectives and a set of fundamental service provider objectives. This paper concludes with an application of the proposed taxonomy to three leading digital services. We hope that the proposed taxonomy will be useful in understanding the science behind the design of digital services.     

Unified modeling for digital twin of a knowledge-based system design

While Model-Based Systems Engineering (MBSE) improves the ambiguity problem of the conventional document-based way, it brings management complexity. Faced with the complexity, one of the core issues that companies care about is how to effectively evaluate, predict, and manage it in the early system design stage. The inaccuracy of contemporary complexity measurement approaches still exits due to the inconsistency between the actual design process in physical space and the theoretical simulation in virtual space. Digital Twin (DT) provides a promising way to alleviate the problem by bridging the physical space and virtual space. Aiming to integrate DT with MBSE for the system design complexity analysis and prediction, based on previous work, an integration framework named System Design Digital Twin in 5 Dimensions was introduced from a knowledge perspective. The framework provides services for design complexity measurement, effort estimation, and change propagation prediction. Then, to represent the system design digital twin in a unified way, a modeling profile is constructed through SysML stereotypes. The modeling profile includes System design digital model in virtual space profile, system services profile, relationships profile and digital twin data profile. Finally, the system design of a cube-satellite space mission demonstrates the proposed unfiled modeling approach.

Management Architecture for ATM Over ADSL-Based Access Networks

ADSL (Asymmetric Digital Subscriber Line) is a new key technology for offering broadband services to home users and small businesses. ADSL technology is ready to take off. Management discussions aim at achieving an ADSL broadband service architecture are still taking place, however. In order to support multiple services over widely spread networks incorporating various transmission techniques, a cost-effective network operation requires an end-to-end network management architecture. We describe here how to integrate ADSL equipment into the existing telecommunications management network. Alternative protocols and information models are also discussed. The overall network management architecture gives the motivation for the management concept applied to our Digital Subscriber Line Access Multiplexer (DSLAM). The design of such a network element covers all management functionality that is required to multiplex ATM connections being transferred over the ADSL system and to integrate the network element into any telecommunications network. We have chosen a flexible approach to adapt the DSLAM management to different usage environments.
