Determining Transfer Batch Sizes in Trip-Based Material Handling Systems
Trip-based material handling systems such as AGV systems or lift trucks are often designed with a given flow matrix (or from-to chart), which typically shows the number of loaded trips that the devices must perform per unit time between the workstations. A from-to chart that would result from the parts flow in a facility actually is dictated by the transfer batch size; that is, the number of pa...
متن کاملExpected waiting time in symmetric polling systems with correlated walking times
Polling systems have been extensively studied, and have found many applications. They have often been used for studying wired local area networks such as token passing rings and wireless local area networks such as bluetooth. In this contribution we relax one of the main restrictions on the statistical assumptions under which polling systems have been analyzed. Namely, we allow correlation betw...
متن کاملWaiting times in queueing networks with a single shared server
We study a queueing network with a single shared server that serves the queues in a cyclic order. External customers arrive at the queues according to independent Poisson processes. After completing service, a customer either leaves the system or is routed to another queue. This model is very generic and finds many applications in computer systems, communication networks, manufacturing systems,...

متن کاملHolonic-based Control System for Automated Material Handling Systems
In real-word manufacturing environments, finding the right job sequences and their associated schedules when resource, precedence, and timing constraints are imposed is a difficult task. For most practical problems classical scheduling easily leads to an exponential growth in the number of possible schedules. Moreover, a decision time period of hours or even minutes is too long. Good solutions ...
