摘要:

SummaryThis article presents a survey of the different methods of productivity measurement, it describes what hitherto has been done in the Netherlands in this field. After an explanation of the concept of productivity and a description of some pre‐war and recent publications on productivity trends in a number of branches of manufacturing industry, the main object is formed by a description of the so called interfirm comparisons of productivity. It stresses the practical importance of comparisons based on quantitive ratios (labour requirements per unit of product, etc.

摘要:

SummaryThe article contains a short review of a campaign, undertaken in Holland during the last 12 years to arrive at standardized sizes for women's and men's clothing. The first campaign was undertaken by a department store, the second one by the clothing industry.The operational value of a sizing system depends on the value of three parameters which are not, of course, independent of each other: coverage of the system, number of sizes and average cost of alterations.The basis of the standardization is furnished by measuring a sample of the population of customers and by measuring the fitting‐tolerances of clothing.The proposed sizing systems are:a. Ladies' dresses — a two‐dimensional system based on waist girth and length of back, containing 14 sizes and giving a coverage of 90%.b. Men's suits — a system with a variable number of dimensions (2 to 4). The identification dimensions are waist girth, length of leg, hip girth and inclination of shoulder. The proposed system gives a coverage of 90% with 34 sizes. Both systems have been experimentally verified.Stress is laid on the necessity of an international sizing standard

摘要:

Summary:Optimum allocation in nested sampling.A problem of optimum allocation in nested sampling is considered [1, 2, 3]. In practice it turned out that, though considerable savings could be realized, the known formulae often do not sufficiently approximate the true optimum sample numbers. This is the case where small samples, unfavourable ratios of costs and variances, or designs with more than two classifications, are concerned. The departures are caused by the discrete character of the problem, whereas the formulae hold for continuous cases.A method for optimum allocation, which takes the discrete character of sample numbers into account, is given together with an example of its application.

摘要:

SummaryThe paper contains a description of field experiments on the use of various implements and of certain working‐methods in the planting of pine forests. The fact that there are two important criteria, i.e. time‐saving and quality of the work, led to a complicated factorial experiment, which was analysed in two different ways, each referring to a part of the d
