The present paper deals with the factors that contribute to assuring the quality of the processes involved in project management. The novelty of the approach consists in the fact that the project management processes are analysed with the help of quality indicators in case of time variance. By...

Abstract Consider a product with quality characteristic X . Assume that the product is composed of n parts each with quality characteristic X i , and and let X = X 1 + . . . + X n Assume that there is a lower specification L and an upper specification U for X . Then the problem arises how to...

Summary Stationary multiplier methods are procedures for rounding real probabilities into rational proportions, while the Sainte-Laguë divergence is a reasonable measure for the cumulative error resulting from this rounding step. Assuming the given probabilities to be uniformly distributed, we...

There are distribution functions, mean value and variance of the uniform and the triangular distributions derived in this paper. The article deals with the procedure how to get the random values above mentioned distributions from pseudo-random numbers by the inverse transformation method. The...

In this paper, we studied estimators based on an interval shrinkage with equal weights point shrinkage estimators for all individual target points ¯θ ∈ (θ0,θ1) for exponentially distributed observations in the presence of outliers drawn from a uniform distribution. Estimators...

A random variable is difference-form decomposable (DFD) if it may be written as the difference of two i.i.d. random terms. We show that densities of such variables exhibit a remarkable degree of structure. Specifically, a DFD density can be neither approximately uniform, nor quasiconvex, nor...
