What Makes True Logistics What Makes True Logistics a Good Negotiation Testbed?a Good Negotiation Testbed?

Dynamic, continuous process:Simultaneous long-range, short range and execution concerns– Six-month to year goals for Marine Expeditionary Units

(MEUs): you, your aircraft, data, systems and 2k friends– Build/maintain weekly and daily schedules– Repair schedules on five minutes notice

Strong good-enough / soon-enough pressures (same reasons)

Contrast to traditional optimization– Cannot elicit full evaluation function in advance– Frequent need to change constraints to handle problem

VERY high military payoffs: Money, Lives

CAMERA / MICANTS Integration PlanCAMERA / MICANTS Integration Plan

1.Scheduling/planning of short-term, tactical, corrective maintenance actions in light of the flight schedule

SNAP supplies daily flight schedule to MAPLANT which in turn generates a daily maintenance plan

2. Scheduling/planning of long-term, strategic, scheduled maintenance actions w.r.t. long-term flight schedule

SNAP supplies n-week flight schedule to MAPLANT which uses that to generate a long term maintenance plan

3. Scheduling flight operations based on plane availability

MAPLANT provides a "best effort" estimates for the number of available aircrafts over time. SNAP creates a schedule based on these estimated generation rates.

4. Scheduling flight operations based on plane availability and capabilities

MAPLANT provides a "best effort“ estimates for the number aircrafts, their capabilities, other attributes, and negotiable and non-negotiable constraints associated with them. SNAP creates a schedule based on this.

5. Negotiation between MAPLANT and SNAP

The two systems interact using a well-defined messaging protocol to facilitate negotiation between the flight schedule and maintenance schedule. The objective is to explore trade-offs between the two aspects to achieve global optimization w.r.t. some metric (e.g., generation rate, CRP, etc.)

Insights and New DirectionsInsights and New Directions

Services rendered by negotiation

– Control systems

– Decision support

Dimensions of scaling to explore

– Speed: tie to replanning during missions

– Size: coordinating much larger organizations

– Planning horizon: very long-range planning

Tasks and TimelineTasks and Timeline

CAMERA: implement SNAP initial assessment milestones (esp. flight hour guidance)

MICANT: scope initial MAPLANT coverage of maintenance issues(portions of T&R manual, Mission Essential Systems List) in order to determine scenario specifics

Week of Dec 18: VTC to define interfaces (probably XML DTDs), flesh out schedule based on scenario specifics

Jan: coordination meeting

Feb: Status review: GO vs. DEFER decision on scheduling

If decision is GO, then:– Issue invitations to major constituents for high-profile demo in April

– Schedule March integration and first rehearsal meeting

– April: provide major demonstration at MCAS Yuma and/or other venues
