Negotiation Mechanism

This article presents a novel market-based mechanism for a dynamic coalition formation problem backgrounded under real-time task allocation. Specifically, we first analyze the main factors of the real-time task allocation problem, and formulate the problem based on the coalition game theory. Then, we employ a social network for communication among distributed agents in this problem, and propose a negotiation mechanism for agents forming coalitions on timely emerging tasks. In this mechanism, we utilize an auction algorithm for real-time agent assignment on coalitions, and then design a mutual-selecting method to acquire better performance on agent utilization rate and task completion rate. And finally, our experimental results demonstrate that our market-based mechanism has a comparable performance in task completion rate to a decentralized approach (within 25% better on average) and a centralized dynamic coalition formation method (within 10% less on average performance).

To realize RTX, a 32-bit ARM processor platform and Keil was used to provide a graphical interface. Through real-time task allocation and Keil provided by TCP/IP interface, an embedded ultrasonic welding control system was realized. The ultrasonic welding control system designed for the testing of software and hardware, and by comparison with field work, proved that the application of multitasking can obviously improve the welding effect through welding control system, friendly man-machine interface, convenient communication and monitoring.
