Outline

• Multichannel Adaptive IS
• MAIS goals
• MAIS Architecture
• Research problems
• Results and ongoing research

MAIS Multi-channel ADAPTIVE information systems
- access to e-services - cooperative processes

• Tourism
• E-learning
• Risk management

MAIS goals

• Develop methods, models, and architectures for
  multichannel adaptive information systems
• Multichannel
• Mobile information systems
• Service provisioning web, e-mail, sms,
  client-server
• Heterogeneity, dynamic evolution of channels
• Device characteristics
• Network connections
• Adaptation to context
• User model
• Service provisioning
• Channel of invocation, QoS
• Hardware low power consumption processors, VSBD

Research focus
ADAPTIVITY

• Adaptive orchestration of e-services
• Reflexive architecture for context-aware services
• Adaptive networks
• Low power consumption processors
• Methods and tools for multichannel interface
  design and integration
• Application areas e-learning, tourism, emergency
  teams

Research problems

• Dynamic selection of services
• On the basis of
• quality parameters
• user request and user profile
• Context
• When
• Preselection
• For each process instance
• For each operation
• Negotiation (quality levels, price)
• Substitution
• Dynamic process evolution

MAIS services orchestration
MAIS functional architecture
13
MAIS adaptive e-service architecture
E-Service Composition Platform
Orchestration
Chooses the best e-service according to user
request
Invokes the choosen service
Architectural strategies
MAIS reflective architecture
14
General Architecture
Interaction Enabling Platform
chooses the best n-ple for service delivering
determines QoS levels acceptable for the user
translates logical constraints in technological
ones
merges service/user/context constraints
15
General Architecture
Reflective Platform
Works on a given n-ple
Receives as input the acceptable QoS levels with
their constraints
Monitors the channel during service provisioning
Attempts a channel adaptation trying to change
the real values
