The performance of flow lines is significantly affected by the failures and the repair activities that the machines go through. The manufacturing process models based on Petri nets with time are developed for single work station, including a stochastic failure process and a repair process. The models consider two failure detection modes and three interrupted-job-handling policies. To study the influence...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
We present a novel hybrid approach for performance analysis of a system design. Unlike other approaches in this area, in this paper we do not focus on the determination of pessimistic best-case and worst-case quantities of system properties. Our proposed analysis methodology determines qualitative numbers between best-case and worst-case of system properties and quantifies them with probabilities...
