Analysing the performance of an automated pathology specimen handling system
This paper determines the performance of a pathology specimen handling system currently under development that performs two fundamental functions, sample tube sorting and sample tube aliquoting. In order to do this a novel capacity model and a simulation model have been developed to analyse the performance of the machine. A capacity model and a simulation model are necessary in order to measure the efficiency of the conveyor system as a means of transferring pucks and tubes between modules as each is insufficient on its own. Furthermore strategies for controlling the machine and eliminating deadlocks are also developed in order to optimise the machine performance and to make it robust. From numerical investigations the best number of pucks and the best puck queue sizes are determined in order to maximise throughput. The results show that a complex relationship exists between the number of pucks, the puck queue sizes and the primary tube arrivals and keeping these components in balance is essential in maintaining system performance.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
