The Petri net model presented in this paper focuses on the modeling and the simulation of the medicals bidding behavior and the service system dispatch by the doctors. Where Petri net models capture its stochastic and distributed characteristics. A hybrid multilayer Petri net market simulator, which combines the modeling of physical, owes and information owes, is proposed. The base layer is the physical layer, where the service transmission networks are modeled. On top of it are information layers modeling information owes which schedule the physical owes via discrete tokens. In between, there is an interface layer coded as programs and functioning as a control agent. Colored Petri nets are used to simulate the information layer, in which the uncertainties presented in the decision making process during the bidding and the parallel behaviors of the bidders are modeled. An extension of continuous Petri nets, called a Variable Arc Weighting Petri net (VAWPN), is introduced to simulate the physical layer, in which vector tokens are used to match the information owes to the physical owes and distribution factors are used to obey the physical laws of the service. The market simulator consists of three major modules: the ISO module, the Medical Organization (MO) module and the Load module. The Independent System Operator (ISO) module simulates the priority-based service distribution process following a Location based Marginal Pricing (LMP) scheme. In addition to allowing the medical bids to be functions of price, the algorithm also accepts load bids as functions of price. Bidding strategies are developed for various types of medicals, based on which a medical organization module is developed to provide medical bids to the ISO module. With the price feedback from the ISO module, the MO module can allow the bidders to adjust their bids or switch bidding strategies. The Time Sharing Entity (TSE) model develops load bids to the ISO model. TSE are considered to be either an aggregated demand or price sensitive block bids depending on the situation studied. Impacts of medical bidding strategies on the market clearing prices (MCP) are discussed based on the simulation results. Future research directions in this area are also addressed.
