2. Introduction Milestone 1 Milestone 2
Create two scenarios for JiT Medical Application
Unable Patient Scenario
Able Patient Scenario
Create UML sequence diagram for scenarios
Milestone 2
Formalize the scenarios
Timing constraints
Orchestration and Choreography
Software Tool MagicDraw (12.5 EAP beta 1)
Provides tools to draw UML, orchestration, choreography diagrams
Representation of scenarios via pi-Calculus

3. Scenario – Unable Patient
Sensor Equipment takes video/picture of Patient
Data sent to Condition and Record Agent for storage
Sensor detects alarm and alerts Hospital
Hospital receives alarm and alerts Physician and Nurse
Physician queries Patient’s Current Condition for Diagnosis
Physician Requests Nurse/Dispatch to perform action
After action is performed, Doctor again queries Patient’s condition for outcome of action

4. Sequence Diagram - UML

5. Orchestration – Execution Flow

6. Choreography – Agent Collaboration

7. Scenario – Able Patient
Patient takes reading (temperature) by sensor equipment
Data sent to Condition and Record Agent for storage
Sensor detects alarm and alerts Hospital
Hospital receives alarm and alerts Physician and Nurse
Physician queries Patient’s Current Condition for Diagnosis
Physician sends an Action to be performed by Patient
After action, Physician again queries for updated Condition of Patient

8. Sequence Diagram - UML

9. Orchestration – Execution Flow

10. Choreography – Agent Collaboration

11. Formalization using Pi-Calculus
State Transition of Data & Alert Propagation

12. Formalization using Pi-Calculus
Sensor Data Propagation Notation:
(Patient(data!); Sensor(data?,data!); Condition(data?,data!); Records(data?))*
Alarm Propagation Notation:
Patient(data!); Sensor(data?,alarm!); (Condition(alarm?,alarm!); Records(alarm?))|(Hospital(alarm?, alarm!);(Expert(alarm?)|Nurse(alarm?)))
Notation Symbols:
; - sequential composition
? – input data
! – output data
* - iteration
| - parallel composition
