4 4 A More Collaborative & Dynamic Planning and Execution Framework  Human relatable and presentable objectives, issues, sense- making, advice, multiple options, argumentation, discussions and outline plans for higher levels  Detailed planners, search engines, constraint solvers, analyzers and simulators act as services in this framework in an understandable way to provide feasibility checks, detailed constraints and guidance  Sharing of processes and information about process products between humans and systems  Current status, context and environment sensitivity  Links between informal/unstructured sense-making and discussion and more structured planning, methods for optimisation and decision support

6 6 Framework  Common conceptual basis for sharing information on processes and process products  Shared, intelligible to humans and machines, easily communicated, formal or informal and extendible  Set of restrictions on things of interest: IIssuese.g. what to do? How to do it? NNodese.g. include activities or product parts CConstraintse.g. state, time, spatial, resource, … AAnnotationse.g. rationale, provenance, reports, …  Shared collaborative processes to manipulate these: Issue-based sense-making (e.g. gIBIS, 7 issue types) Activity Planning and Execution (e.g. mixed-initiative planning) Constraint Satisfaction (e.g. AI and OR methods, simulation) Note making, rationale capture, logging, reporting, etc.  Maintain state of current status, models and knowledge  I-X Process Panels (I-P 2 ) use representation and reasoning together with state to present current, context sensitive, options for action Mixed-initiative collaboration model of mutually constraining things

7 7  The I-X approach involves the use of shared models for task- directed communication between human and computer agents  I-X system or agent has two cycles: Handle Issues Manage Domain Constraints  I-X system or agent carries out a (perhaps dynamically determined) process which leads to the production of (one or more alternative options for) a “product”  I-X system or agent views the synthesised artifact as being represented by a set of constraints on the space of all possible artifacts in the application domain I-X Approach

30 30 Some Planning Features  Expansion of a high level abstract plan into greater detail where necessary.  High level ‘chunks’ of procedural knowledge (Standard Operating Procedures, Best Practice Processes, Tactics Techniques and Procedures, etc.) at a human scale - typically 5-8 actions - can be manipulated within the system.  Ability to establish that a feasible plan exists, perhaps for a range of assumptions about the situation, while retaining a high level overview.  Analysis of potential interactions as plans are expanded or developed.  Identification of problems, flaws and issues with the plan.  Deliberative establishment of a space of alternative options, perhaps based on different assumptions about the situation involved, of especial use ahead of time, in training and rehearsal, and to those unfamiliar with the situation or utilising novel equipment.

31 31 More Planning Features  Monitoring of the execution of events as they are expected to happen within the plan, watching for deviations that indicate a necessity to re-plan (often ahead of this becoming a serious problem).  Represent the dynamic state of the world at points in the plan and use this for ‘mental simulation’ of the execution of the plan.  Pruning of choices according to given requirements or constraints.  Situation dependent option filtering (sometime reducing the choices normally open to one ‘obvious’ one.  Satisficing search to find the first suitable plan that meets the essential criteria.  Heuristic evaluation and prioritisation of multiple possible choices within the constrained search space.  Uniform use of a common plan representation with embedded rationale to improve plan quality, shared understanding, etc.

32 32 Human Approach  Previous slides describe aspects of problem solving behaviour observed in expert humans working in unusual or crisis situations.  Gary Klein, “Sources of Power”, MIT Press, 1999.  But they also describe the hierarchical and mixed initiative approach to planning in AI developed over the last 25 years.
