TL;DR: In this article, the value of a single payment new compared to another payment in the future is compared to a series of periodic payments in the past and a uniform series of payments.

TL;DR: In this article, the optimal timing of repair or replacement occurs when the cost per unit of water from the old system becomes more than the minimum annualized cost of water for the new system.
Abstract: Significant savings are frequently achieved from increasing well and pump efficiency by repair or replacement. Replacement analysis (a part of engineering economics) may be used to schedule these actions. The criterion is to maximize net benefits or minimize the cost of water. The optimal timing of repair or replacement occurs when the cost per unit of water from the old system becomes more than the minimum annualized cost per unit of water from the new system.

TL;DR: In this paper, a comparison of alternate cogeneration plants with an existing steam-only plant in terms of energy conservation and engineering economics is made. And the concept of marginal cost of production is applied throughout.

TL;DR: In this article, a definition of engineering economics is formulated, which requires that all the effects of all subsidies should be eliminated from all the factors involved in engineering economic comparisons of alternative facilities.
Abstract: A definition of engineering economics is formulated. This definition mandates that all the effects of all subsidies should be eliminated from all the factors involved in engineering economic comparisons of alternative facilities. It also requires that the effects of inflation on the economic costs of goods and services and on the cost of money also all be included in the evaluations. On-the-other-hand, it suggests that purely financial expenses, money costs, such as, for example, income taxes, not be included in such studies.
