Pig production is a very important branch around the world. The paper deals with technical efficiency of pig farms using Data Envelopment Analysis (DEA). DEA is a technique for measuring of relative performances of different production units, where the presence of multiple inputs and outputs...

This article deals with practical problems of fitting empirical data with generalized lambda distribution. Given method based on moment matching is illustrated on a practical example.

The duration of all or some activities in stochastic projects is a random variable. It is advantageous to generate values of random activity durations with beta probability distributions. We can carry out time analysis of stochastic projects by means of simulation.

Our work has several aims. We have evaluated the Quality of life of the regions (NUTS 3 regions) in the Czech Republic, according to the selected criteria by the Data Envelopment Analysis (DEA) method. This method was initially proposed to evaluate the efficiency. In this paper, the level of...

This article deals with a comparison of 16 fire stations of a factual region of the Czech Republic with the use of a DEA model. The number of actions (output) and the number of employees, the level of fire equipment and the inside area (inputs) were obtained for each of the fires stations using...

Data envelopment analysis (DEA) is used as a tool for technical efficiency evaluation of decision making units. These units are compared with each other. The comparison is based on the size of inputs and outputs. In case of an inefficient unit, there is a possible of ordaining necessary changes...

This article deals with approximation of empirical distribution to standard normal distribution using Johnson transformation. This transformation enables us to approximate wide spectrum of continuous distributions with a normal distribution. The estimation of parameters of transformation...

The main goal of this contribution is to suggest to computer assembling company the optimal replacement of the most critical computer component according to criterion of the minimum guarantee repairs costs during warranty period. Guarantee repair costs were calculated using a method of decision...
