The optimal production and advertising policies for an inventory control system of deteriorating multi-items under a single management are formulated with resource constraints under inflation and discounting in fuzzy environment. Here, the deterioration of the items and depreciation of sales are at a constant rate. Deteriorated items are salvaged and the effect of inflation and time value of mo...

The work analyzes current technologies of ore mining applying self-propelled equipment in underground conditions; studies practices using the general and for broken transportation only; considers performance enterprises similar mining-geological miningtechnical generalizes causes high loss dilution rates Kryvyi Rih iron basin, thus revealing a problem providing efficiency increased extraction w...

We discuss the effects of the off-shell nucleon propagation for the particle production. Results from nonequilibrium Kadanoff-Baym evolution modeling a heavy ion collision are presented. The production rates are compared to equilibrium emission rates obtained in the same approximation for the self-energy. The comparison of semiclassical and quantum in-medium production rates is performed within...

Successful pasture-based milk production systems pivot on balancing dairy cows’ feed requirements with seasonal and annual fluctuations in pasture production. In order to maximise cow production from grazing dairy systems, it is necessary to reach an efficient utilization of grazed grass for feeding cows and the development of appropriate grazing management systems designed to maximize daily pa...
