  2. Recap - Problem Context • Problem Context: • Modern organisations are virtual entities; • People involved are located in different places, each with different capabilities and responsibilities; • People needs to work collaboratively to accomplish tasks and together achieve organisational goals; • Such tasks often require sophisticated technology that is based on local expertises and domain knowledge. • Two Enabling Technologies: • Workflow and Business Process Modelling techniques: Edinburgh; • Constraint-based Problem Solving techniques: Aberdeen; • Collaboration and integration of the two.

  6. Example start_junction( “Confirm Entering Clearing Process”). process( “Confirm Entering Clearing Process”, Instance, ccs(X), or(past_due_date(Student), not_successful(Student)), update_status(Student, “clearing”) ). link(“Confirm Entering Clearing Process”, “Execute Clearing Process”).

  7. Example Process process(Instance, 'Receive Customer Request'/1, created, Priority, _Begin_time/_End_time, 1, (Requester/Requester_type, edinburgh/pc_specification), [event_occ(Instance, customer_request_for_pc_specification, received/_, Priority, _Begin/_End, (Requester/Requester_type, _Provider/_Provider_type), _Event_content) ], [true], [cond_action([not_exist(instance_of(Requester, customer))], [create(instance_of(Requester, customer))] ), create(instance_att(Requester, event, Instance)), create(instance_of(Instance, event)) ], [exist(instance_of(Requester, customer)), exist(instance_att(Requester, event, Instance)), exist(instance_of(Instance, event)) ] ).
