BIRIS framework and characteristics

9. Life Cycle of Virtualized Service Resource in BIRIS Environment
Business framework of BIRIS
 BIRIS: BI-lateral client-oriented Resource Integration Service mode
Third-Party Service Agency
Customer Side Provider Side
Centralized Quality and Credit Control

10. Life Cycle of Virtualized Service Resource in BIRIS Environment
Key innovative characteristics of BIRIS mode
 Personalized/customized new service content/new service approaches
– Market subdivision brings up enormous services both in market and on the web,
The cost for building “requester-supplier” relationship for both sides grows violently
 Added customer value
– Usage value: enhanced business value of customers in service chain/quality
– Enjoyment value: Addition to or deepening of service content/service approach
– Scale value: enlarged customer groups, refined customer classification and
enriched service content
 Establishment of service center/service delivery center
– To provide unified practices for service, quality criteria, pricing
– To integrate customers, personalization, credit, call center, etc
 Integration of dispersed service resources into virtualized resources
– To offer value-added virtual service by integrating multiple service resources
provided by multiple service providers
– To overcome the limitedness of service resources under traditional service modes

11. Life Cycle of Virtualized Service Resource in BIRIS Environment
Key innovative characteristics of BIRIS mode
 Service solution/evolutionary solution for service adaptability
– Service asset reuse, context-aware/autonomy
– Service on demand, selectable, configurable, personalization
 Life cycle oriented definition, recommendation, evaluation and
optimization of service quality
– Define service quality indicator structure and evaluation methods
– Tracking, feedback, and optimization to current service system
 Accumulation and utilization of historical credit of both sides of service
participants
– Establish credit system for customers, to restrict them from bad behaviors
– Establish credit system for comprehensive assessment to providers
 Internet-based/IT-enabled platform to support services
– SOA/SaaS based service business application platform
– IT infrastructure platform for service system
– Environment for service design and implementation

14. Life Cycle of Virtualized Service Resource in BIRIS Environment
What’s VSR?
 Virtualized service resource (VSR)
– A physical- cyber mapping from resources in real world to software / IT world
– A integration of services resources from different sources and providers
 Example of VSR
Virtualized Warehouse

15. Life Cycle of Virtualized Service Resource in BIRIS Environment
Life cycle of virtualized service resource
 VSR reflects the mass integration nature of BIRIS distinctly
– Establishment: a dynamic service composition algorithm is employed to integrate
resources directly from individual ones in real-time
– Selection: multiple resources are selected to perform necessary functionalities and
to exert desired outputs
– Runtime usage: virtualization of human activities and Web service/service
composition technologies are adopted to enable corresponding resources really
work
– Management: VSR has a two-tier structure: capability specific layer and
requirement specific layer
– Discard: to keep virtualization mechanism work efficiently, VSRs with little
possibility of usage should be removed from repository

16. Life Cycle of Virtualized Service Resource in BIRIS Environment
Key techniques for different stages in life cycle
 Establishment of VSR
– 1: Dynamic generation of virtualized service resources
– 2: Credit/quality/personalization based service selection and matchmaking
– 3: Static generation and recommendation of virtualized service resources based on
data analysis

17. Life Cycle of Virtualized Service Resource in BIRIS Environment
Key techniques for different stages in life cycle
 Selection of Virtualized service resources
– Semantic representation of virtualized service resources
– Matchmaking between virtualized service tasks and virtualized service resources
– Matchmaking between concrete services for adjustment of VSR

18. Life Cycle of Virtualized Service Resource in BIRIS Environment
Key techniques for different stages in life cycle
 Runtime usage
– Seamless linkage of human-machine interactions: WS-HumanTask specification
– Theory of service ecosystem
 Management
– Customer community
– Service community
– Performance analysis of virtualized service resources
– Dynamic deployment and runtime adjustment of virtualized service resources
– Personalization/differentiation oriented service resources virtualization
 Discard
– Statistical analysis on quality of VSR
– Credit evaluation of virtualized service resources base on social networks
