Tytuł:: Random errors in analysis of population growth

The model of bacteria population growth in terms of the logistic equation is considered assuming the plate dilution technique of viable counting in the experiment and random errors in data. For example the Fisher test states that the growth equation and the standard description of the random errors are rejected. The extended analysis of errors is presented in terms of an operator which enables to separate three types of random elements: the stochastic growth of dilutions and sampling. On the basis of the triple repetition of observations the variance of dilution errors is estimated.

Opis:: One of the basic characteristics of queueing systems is the stochastic process {n(t),t≥0}, which is defined to be the number of units present in the system at time t. In certain cases, this process is Markovian and then its analysis is relatively simple. When the process {n(t),t≥0} is not Markovian, its "Markovization'' can be accomplished by a suitable extension of the states of the system or by the construction of a suitable imbedded Markov chain. The method of extension of the states of the system, which depends on the formation of a vector process, one of whose components is the process {n(t),t≥0}, gives the characteristics of the process {n(t),t≥0}. The method of imbedded Markov chains, which consists of investigating the process in a suitably chosen sequence of time points, yields the characteristics of the process only at the selected time points. For example, a GI/M/N system may be analyzed at the moments of time at which the units enter the system. Because of this, when the method of imbedded Markov chains is used, the interesting characteristics of continuous-time processes can be obtained only with some additional effort. (MR0467961)

Tytuł:: Estimation of the reliability of systems
Autorzy:: Dziubdziela, W.
Kopociński, B.
Powiązania:: https://bibliotekanauki.pl/articles/748660.pdf
Data publikacji:: 1979
Wydawca:: Polskie Towarzystwo Matematyczne
Tematy:: Reliability, availability, maintenance, inspection
Applications (reliability, demand theory, etc.)
Reliability and life testing
Opis:: MR0549986
The authors survey methods of estimating the reliability of systems under the condition that the probability distributions of survival times of some minimal critical sets of elements are not fully known. The survey includes methods with various degrees of complexity.
