Abstract:	A key problem addressed in the area of multiagent systems 
		is the automated assignment of multiple tasks to executing 
		agents.The automation of multiagent task assignment 
		requires that the individual agents (i) use a common protocol 
		that prescribes how they have to interact in order to come to 
		an agreement and  (ii) fix their final agreement in a contract 
		that specifies the commitments resulting from the assignment 
		on which they agreed. 
                This report is part of a broader research effort
  		aiming at the design and analysis of approaches to automated
  		multiagent task assignment that combine auction protocols and
  		leveled commitment contracts. The primary advantage of such
  		approaches is that they are applicable in a broad range of
		realistic scenarios in which knowledge-intensive negotiation
		among agents is not feasible and in which unforeseeable future
		environmental changes may require agents to breach their 
		contracts.  Examples of standard auction protocols are the 
		English auction and the Dutch auction.  In
  		[2] a combination of English-type auctioning and leveled
  		commitment contracting has been described. In this report the 
		focus is on the combination of Dutch-type auctioning and 
		leveled commitment contracting.
Keywords:	automated task-assignment in multiagent systems,
		auctioning, leveled commitment contracting.
