Final answer:
The process of estimating equipment, human resources, and materials for a project is known as Estimate Activity Resources. It relies on mathematical models and the understanding of variables and their relationships. This process involves careful reasoning and familiarity with factors of production.
Step-by-step explanation:
When estimating the type of equipment, human resources, and quantities of material and supplies required to perform each activity, you are engaging in a vital project management process. This is known as Estimate Activity Resources. The purpose of this process is to predict the resources needed for each task to develop a more accurate schedule and budget.
Utilizing mathematical models is beneficial to estimate costs for various approaches at the early stages of a project. In the same vein, the conceptual linkage between science and cost is established through predictions of operation and maintenance expenses based on these models. This cost estimation is made comparable by normalizing it to a cost per unit such as cost per thousand gallons of water, when considering processes like water treatment.
In physics and engineering, estimating is a skill that's developed over time by combining quantitative thinking and a safe assumption of uncertainties. This includes familiarity with dimensions, units, and scales of base quantities. Estimation strategies rely on understanding how variables may be related, and they often make use of known formulas and limited precision data.
True estimation is much more than making a random guess; it's about using experience, sound reasoning, and correct physical principles to make an educated approximation. This type of estimation, also known as Fermi calculations, is a powerful tool to conduct 'sanity checks' on calculations or proposals and develop physical intuition.
In practice, when you estimate activity resources, you're not just pulling numbers out of thin air. You're carefully considering the physical principles, dimensions of materials, and the relevant variables that might affect the estimations of resources such as labor, materials, and machinery—collectively known as factors of production.
