In order to develop meaningful statistical control limits when applicable based upon the normal distribution, the mean and the standard deviation of a population must be known. In cases when an accurate approximation of the standard deviation is not known, the calculation of reasonable...

Article deals with matters of quantitative methods of creating the optimal range for a small manufacturing enterprise. The classical approach to the formation of an optimal production program based on mathematical methods for linear programming is viewed through the prism of consumer...

The methodologies used for computing levelized busbar costs of electricity from geothermal (hydrothermal) resources used by 16 organizations active in the geothermal area are discussed. The methodologies are compared by (a) comparing the results obtained by using two standard data sets, (b) a...

Since the value of the hydraulic resistance depends on flow rate, problem of flow distribution per pipes in a gas or water distributive looped pipelines has to be solved using iterative procedure. A number of iterative methods for determining of hydraulic solution of pipeline networks, such as,...
