 Enige Statistische problemen in de textielindustrie1A. R. van der Burg Statistica Neerlandica, 1950, vol. 4, issue 1‐2, 7-19 Abstract: Some statistical problems in the textile industry Part A. Production control in a spinning mill. It is pointed out that the function of planning is as important as the functioit of inspection. Sound planning requires reliable knowledge of the actual performances of men and machines. As to the machines, the actual amount of drafting of a spinning mill can not be computed from the speed and diameters of the rollers; instead it is necessary to use a working diameter of the roller found by experimental determination of the lengths of the ingoing and outgoing yarn. The amount of variation in outgoing yarn thickness can be computed from the variation in the ingoing yarn, the amount of draft and the amount of doubling. The necessary formulae are developed and illustrated. Part B. Weavers' efficiency Apart from servicing the machines, the weaver has to spend a certain portion of his time in reparing breaks in the yarn. If too many weavers are employed, they will part of their time have nothing to do; if too few, the machines will stand idle, because breaks can not be repaired soon enough. A formula is developed for finding the number of personnel that will reduce losses to a minimum.
