  • 1. Int’l Conf. Exploring Services Sciences (IESS 2010) February 17-19, 2010 Geneva, Switzerland Xiaofei Xu, Xianzhi Wang, Zhongjie Wang (xiaofei@hit.edu.cn) Research Center of Intelligent Computing for Enterprises and Services (ICES) School of Computer Science and Technology Harbin Institute of Technology, China February 19, 2010
  • 2. Life Cycle of Virtualized Service Resource in BIRIS Environment Where is Harbin Institute of Technology Harbin Institute of Technology (HIT, 1920-) is one of top nine universities in China. The Computing Division in HIT was founded in 1956.
  • 3. Life Cycle of Virtualized Service Resource in BIRIS Environment Beautiful Harbin
  • 4. Life Cycle of Virtualized Service Resource in BIRIS Environment Contents   Background   BIRIS framework and characteristics   Core elements of BIRIS: virtualized tasks and virtualized service resource   Technical architecture and typical applications of BIRIS   Future work   Other research work related to service engineering at HIT-ICES
  • 5. Int’l Conf. Exploring Services Sciences (IESS 2010) February 17-19, 2010 Geneva, Switzerland Background
  • 6. Life Cycle of Virtualized Service Resource in BIRIS Environment Emergence of BIRIS: marine logistics service   Problems in current services: –  marine logistics service Truck company Customs resources Weihai Logistics Inchon tasks tasks China service platform Korea resources resources Cargo owners Cargo owners (consigners) (consignees) Ship owners Freight forwarders Dock and warehouse
  • 7. Life Cycle of Virtualized Service Resource in BIRIS Environment Emergence of BIRIS: marine logistics service Logistics service platform
  • 8. Int’l Conf. Exploring Services Sciences (IESS 2010) February 17-19, 2010 Geneva, Switzerland 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
  • 12. Int’l Conf. Exploring Services Sciences (IESS 2010) February 17-19, 2010 Geneva, Switzerland Core elements of BIRIS: virtualized tasks and virtualized service resources
  • 13. Life Cycle of Virtualized Service Resource in BIRIS Environment Why VSR (Virtualized Service Resources)?   Core mechanism in BIRIS virtualization Individual Virtualized requirements requirements/Tasks Matching/mapping virtualization Virtualized Individual resources resources   Example of a Virtual Service Task requesting 5.5 containers Cargo owner A requesting 20 containers requesting 14.5 containers virtualization Cargo owner B
  • 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 service Resource Container loading Virtualized service Resource Truck company A Cargo owner Truck company B Cargo fetching
  • 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 Establishment Selection Runtime usage Discard of VSR of VSR of VSR of VSR Management of VSR
  • 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 Virtualized Virtualized service task service resource Procedure of VSR selection Step 1: functional matching; function function Step 2: non-functional matching function ---- value Input/Output name ---- quality ---- credit/risk; Quality element Step 3: task traits objectives decomposition; traits Value Step 4: for each task, goto Step 1. structure constraints Credit/Risk utilization
  • 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
