Final answer:
The question focuses on estimating future operating, maintenance, and replacement costs as part of the engineering design process. Mathematical models are used to predict these costs, and costs are normalized for comparison. Present discounted value and energy cost calculations play a vital role in determining the viability of different designs.
Step-by-step explanation:
Understanding the Cost Estimation in Engineering Design
The question posed pertains to the calculation of expected future operating, maintenance, and replacement costs in the context of engineering design. Specifically, such cost estimations assist owners in developing realistic design and budget estimates.
This involves creating mathematical models and strategies to estimate costs for different designs and features. These estimations help analyze the technical feasibility and financial viability of a project by predicting cost implications over a product's lifecycle, including its operation and maintenance.
To calculate these costs, engineers use mathematical models to generate rough cost estimates for various approaches during the initial design phase. These models consider materials, fabrication, manufacturing, operational, and maintenance expenses.
Notably, costs must be normalized, such as cost per thousand gallons of water treated, for the sake of comparison between different options. The present discounted value is often employed to assess the long-term financial implications of the design choices, comparing a set of present costs to the discounted value of future benefits.
Additionally, engineers explore different designs to understand their characteristics and the pros and cons of each. Financial resources availability is another consideration, yet a great design is not solely dependent on a substantial budget. When assessing operating costs specifically, one common strategy is to calculate the energy used in kilowatt-hours and then multiply by the cost per kilowatt-hour.
All of these considerations are a part of the comprehensive engineering design process, which ultimately aims to produce the most cost-effective and efficient solution feasible.
