Methods: The data envelopment analysis(DEA),stochastic frontier cost model(Frontier model) and Spearman rank correlation analysis were used to study the technical efficiency,allocation efficiency and systematic efficiency of 23 hospitals in 3 areas.
The thesis comprehensively has applied such basic speculative knowledge as mathematical statistics regression analysis, computational techniques, costs management, equipment management and mining for copper, aiming at the actuality of some open-pit copper-miner stope excavator production and maintenance management, to estimate model optimal parameters and accurately establish excavator daily maintenance costs model, indirect maintenance costs model and common-use maintenance costs model;
When Quick-Germ was integrated into a state-of-the-art dry-grind fuel ethanol process, computer simulation and cost models indicated savings of approx $0.01/L of ethanol ($0.04/gal) with the Quick-Germ process.
Based on this improvement model, two cost models for determining the optimal overhaul interval and the number of overhauls in a renewal cycle, that minimize the expected unit-time cost or the total discounted cost, are established.
Existence conditions of optimal solutions are obtained and special cases of the two cost models are discussed.
Methodologically, we incorporate traditional expected cost models and study the robustness of the two approaches.
Cost models for future software life cycle processes: COCOMO 2.0
In the context of a Helpman-Krugman-cum-trade-costs model, we derive four empirically testable hypotheses regarding intra-industry trade and trade costs.
The results provide mechanistic support for the hypothesis that Daphnia chose their habitat according to an Ideal Free Distribution with Costs model.
This essay draws on the transaction costs model of the firm and an Austrian perspective on the knowledge problem in centrally planned orders to propose an empirically useful Austrian theory of central planning.
In the transactions costs model in Table 1, this combination of features is exhibited by the pure agglomeration model.
Lots of information is obtained and a very accurate initial and operating costs model is established.
