This paper presents market-based workﬂow management, a novel approach to workﬂow speciﬁcation and execution which regards activities contained in a workﬂow as goods traded on an electronic market. Information about expected cost and execution time is considered for activity speciﬁcations, and is used at runtime to execute workﬂows such that actual cost and execution times are balanced and optimized. To that end, task assignment uses a bidding protocol, in which each eligible processing entity speciﬁes at which price and in which time interval he/she can execute the activity. The winner of a speciﬁc bidding process is requested execute the activity, and earns the amount speciﬁed in the corresponding bid. Market-based workﬂow management thus not only allows to optimize workﬂow executions with respect to execution time and overall cost; but the trading of activities represents an incentive for processing entities to engage in a workﬂow.
