The original is from Voltaire's Candide and referred to the execution of Admiral John Byng. [45] pourboire lit. "for drink"; gratuity, tip; donner un pourboire: to tip. prairie
Efficiency is the often measurable ability to avoid making mistakes or wasting materials, energy, efforts, money, and time while performing a task.In a more general sense, it is the ability to do things well, successfully, and without waste.
The relative efficiency of two unbiased estimators is defined as [12] (,) = [()] [()] = ()Although is in general a function of , in many cases the dependence drops out; if this is so, being greater than one would indicate that is preferable, regardless of the true value of .
The first fundamental welfare theorem provides some basis for the belief in efficiency of market economies, as it states that any perfectly competitive market equilibrium is Pareto efficient. The assumption of perfect competition means that this result is only valid in the absence of market imperfections, which are significant in real markets.
High utilization rates can indicate efficient use of resources, though they must be balanced to avoid overworking machinery or personnel. Cost Efficiency: Analyzing the cost to produce a unit of product or service is crucial. This involves monitoring direct costs, indirect costs, and overheads to ensure optimal spending.
Efficiency (finance), non-mean-variance portfolio analysis, a way of showing that a portfolio is not efficient; Efficiency (mechanical) Efficiency (network science), a measure of how efficiently a network exchanges information; Efficiency (statistics), a measure of quality of an estimator, experiment, or test
Resource efficiency is the maximising of the supply of money, materials, staff, and other assets that can be drawn on by a person or organization in order to function effectively, with minimum wasted resource expenses.
Note that a Carnot engine is the most efficient heat engine possible, but not the most efficient device for creating work. Fuel cells, for instance, can theoretically reach much higher efficiencies than a Carnot engine; their energy source is not thermal energy and so their exergy efficiency does not compare them to a Carnot engine.
