An example (but not the only) interpretation of utility is an action's relative importance, which otherwise is independent of its timeliness. The traditional deadline represented as a TUF is a special case—a downward step of utility from 1 to 0 at the deadline time—e.g., timeliness without importance.
In economics, utility is a measure of a certain person's satisfaction from a certain state of the world. Over time, the term has been used with at least two meanings. In a normative context, utility refers to a goal or objective that we wish to maximize, i.e., an objective function.
It is calculated as the present discounted value of future utility, and for people with time preference for sooner rather than later gratification, it is less than the future utility. The utility of an event x occurring at future time t under utility function u, discounted back to the present (time 0) using discount factor β, is
For example, consider an investment opportunity that has the following characteristics: pay a utility cost of C at date t = 2 to earn a utility benefit of B at time t = 3. At date t = 1 , this investment opportunity is considered favorable; hence, this function is: − δC + δ 2 B > 0 .
Hence, his utility is (,). In a cloud computing environment, there is a large server that runs many different tasks. Suppose a certain type of a task requires 2 CPUs, 3 gigabytes of memory and 4 gigabytes of disk-space to complete. The utility of the user is equal to the number of completed tasks.
Many examples exist in the financial world, for example, where it is reasonable to assume that there is an implicit risk that the reward will not be available at the future date, and furthermore that this risk increases with time. Consider paying $50 for dinner today or delaying payment for sixty years but paying $100,000.
Utility bills cover essential household services such as electricity, sewer, water, trash pickup, phone, internet and gas. The bills can add up -- a GOBankingRates study found that 30% of Americans...
For example, an individual with severe asthma could be offered 10 years in their current condition, or a shorter length of time in full health. If this individual is willing to trade off two of the ten offered years in order to regain full health, this suggests that eight years in full health has the same value as ten years with severe asthma.
