Components Affecting Changes in Gross Profit and Net Profit Initiation

Determination of the largest pit with the non-negative net profit in the open pit mines

The determination of the Ultimate Pit Limit (UPL) is the first step in the open pit mine planning process. In this stage that parts of the mineral deposit that are economic to mine are determined. There are several mathematical, heuristic and meta-heuristic algorithms to determine UPL. The optimization criterion in these algorithms is maximization of the total profit whilst satisfying...

The economics of for-profit and not-for-profit hospitals.

This paper examines the economics of for-profit and not-for-profit hospitals through the prism of capital acquisitions. The exercise suggests that of two hospitals that are equally efficient in producing health care, the for-profit hospital would have to charge higher prices than the not-for-profit hospital would, to break even on capital acquisitions. The reasons for this divergence are (1) th...

Groningen Net profit flow per country from 1980 to 2009

Invited review: selection on net merit to improve lifetime profit.

Genetic selection has made dairy cows more profit-able producers of milk. Genetic evaluations began with 2 traits measured on a few cows but now include many traits measured on millions of cows. Selection indexes from USDA included yield traits beginning in 1971, productive life and somatic cell score beginning in 1994, conformation traits in 2000, and cow fertility and calving ease in 2003. Th...
