摘要:

SummaryReliable information on a morbidity pattern of a population can give us comprehensive ideas how the medical care, and a medical research programme must be organized.To get this reliable information operational methods have to be used. These methods are dealt with in this article.Some suggestions and conclusions for a health care policy are given.

摘要:

SummaryThis lecture deals with a general view on forecasting and planning with special emphasis on the application in less developed countries.After some introductory remarks attention is paid to the evaluation of the results of forecasting by means of statistical methods in comparing forecasts and realization.The paper gives some outlook on the general features of planning in the less developed countries. Special attention is drawn to a rather new aspect of the matter: the importance of non‐economic factors which may have great influence on the process of development. Thorough investigation in this field seems necessary as it may contribute to a better planning and to more efficient activities in these countrie

SummaryAfter some general remarks about tolerance regions two simple cases are considered: the distribution‐free tolerance region and a one‐sided tolerance region for a normal distribution. For a p‐content tolerance region at confidence level γ the equivalent hypothesis‐testing problem is considered which, as a special case, includes the one sided quanti

摘要:

SummaryStatistics and planning do not function as yet in the social sector in the same way as they do in the economic sector, where national accounts and balances are used as frameworks for the integration of the various economic statistics.On the one hand economic sector studies can be made for the social sector as well, giving a picture of the total costs and the financing of the various kinds of social care; on the other hand it is necessary that for each kind of social care (education, medical care, care for the maintainance of law, order and safety, religious care, care for labour and spending of leisure time, housing and social work) social input‐output tables be composed regarding the “cared‐for” as well as the “caretakers”, giving in the form of a matrix the flows of persons passing through each sector of care.If projections are based on such matrices, planning becomes possible and in this way shortages and surpluses can be located in time and a long term policy can be pursued.The various basic statistics will have to be brought into harmony with the requirements of the composition of such input‐output tables for each cohort. To reach this goal two ways are open: either by collecting information for each individual entering a care‐sector about one or more previous situations or by following the individuals through various situations of entering, passing through and leaving care‐sectors. This latter method, the method of the so‐called longitudinal statistics, provides greater possibilities because extrapolation is easier and one can link the different previous situations. The relevant factors can be quantified and the data for model building become available.The development in registration and in automation makes the compilation of longitudinal statistics ‐far as necessary on a sample basis ‐

摘要:

SummaryAutomatic market regulation.The free market system can be considered as a cybernetic process. Due to time lags between decisions and realisation this type of process can generate cycles (Cobweb theorem).It is often tried to puts limits to desastrous price fluctuations be means of international product agreements. It cannot be claimed, however, that these agreements are satisfactory. The author's opinion is that the main difficulty is caused by the fact that the governments do not negociate on a working cybernetic process but on price limits.The author shows the possibility to smooth price fluctuations by means of buffer stocks. Selling and buying are exactly defined by given formulae. The system allows the market to find its equilibrium price; this essential task of a market mechanism is not affected by the buffer system.A system has been given in detail for the pork market. The consumer's price has to be increased by some 0,7 % in order to compensate the costs of reducing the price fluctuations to about 60 % of the original value. This example has only illustrative value.

摘要:

SummaryIn the introduction, it was stated that the development of quick calculating methods has to he regarded as of great importance for the total planning process in a company. The drawing up of the profit forecasting model is one of the most succesful contributions to this. Not only is the objective fulfilled to give a concrete content to the suppositions in the planning process in terms of contributions to more profit, but numerous subsidiary advantages are obtained. The drawing up of afore‐casting model demands a thorough analysis of the behaviour of revenue and expenses at fluctuating volumes. This in itself is already very useful. Further, one will experience that ‐ after first hesitating ‐ many in the concern will be interested in simple forecasting models. This is because these models can often elucidate what complicated administrative application systems leave unsolved. In setting up a model it is better, if one's time is limited, to start with a simple one and improve it gradually as experience is obtained rather than to try to create a more realistic but also more complicated model which will require a long research time. Moveover, a simple model can always be extended to a more complicate
