Abstract

A suitable method for distributed transportation scheduling isnecessary for the development of an agent-based logistics supportsystem for the Australian DefenceForce.Manager Agents (MA) requireresources to be transported, in large quantities and on a globalscale, using the services of many Transport Agents (TA). In thispaper, we investigate the application of Fisherís ExtendedContract Net Protocol (ECNP) to our transportation domain.ECNPprovides a distributed and reactive approach to transportationscheduling that is fairly suited to this domain, but has itsshortfalls. This includes the inability for TA to bid for partialroutes, in addition to partial quantities, for a transportationtask. A new protocol is proposed, based on ECNP, called theProvisional Agreement Protocol (PAP), which overcomes theseshortfalls. Five speech acts, together with policies regarding thepersistence and commitment of tasks and bids, are proposed. Thisallows agents to revisit bid options that were previously selected,and thus accomodates bidding for partial routes.
