Durability is the ability of a physical product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime. [ 1 ] : 5 There are several measures of durability in use, including years of life, hours of use, and number of operational cycles. [ 2 ]
A car is a durable good. The gasoline that powers it is a non-durable (or consumable) good.. In economics, a durable good or a hard good or consumer durable is a good that does not quickly wear out or, more specifically, one that yields utility over time rather than being completely consumed in one use.
It is also different from product economic life which refers to the point where maintaining a product is more expensive than replacing it; [2] from product technical life which refers to the maximum period during which a product has the physical capacity to function; [3] and from the functional life which is the time a product should last ...
This topic is called reliability theory, reliability analysis or reliability engineering in engineering, duration analysis or duration modelling in economics, and event history analysis in sociology. Survival analysis attempts to answer certain questions, such as what is the proportion of a population which will survive past a certain time?
To overcome the durability problem, durable good manufacturers must persuade consumers to replace functioning products with new ones or to pay them money in other ways. Replacement of functioning goods refers to business strategies that persuade or force consumers to purchase new products.
Thermoeconomics can be thought of as the statistical physics of economic value [2] and is a subfield of econophysics. It is the study of the ways and means by which human societies procure and use energy and other biological and physical resources to produce, distribute, consume and exchange goods and services, while generating various types of ...
Econophysics is a non-orthodox (in economics) interdisciplinary research field, applying theories and methods originally developed by physicists in order to solve problems in economics, usually those including uncertainty or stochastic processes and nonlinear dynamics.
The first component, the constant stocks, is similar to the concept of the stationary state, originally used in classical economics; the second component, the flow of natural resources, is a new ecological feature, presently also used in the academic discipline of ecological economics. The durability of both of the constant stocks is to be ...
