The aim of this study was to determine key factors to promote increased life of swimmers which currently fail mostly by metal pick-up. There was insufficient data to build mathematical models for swimmer failure; it is recommended that systematic data collection take place using statistical quality control principles. date: 1991 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/450/1/Production-life-of-tube-swimmers.pdf identifier: Robinson, N.
