When an engineer designs and prototypes a system, it is important they analyse:

All of the other chocies

The inputs to the system

The outputs of the system

The interconnections between the components of the system

The components of the system

When taking measurements of a time-varying system, it is important to:

Pause the system, and hold it fixed while taking the measurements

Move at the same, or faster, speed compared to the system

Stand well back

Take the measurement samples at an appropriate rate, and with an appropriate amplitude quantisation resolution

When designing a system, it is important for engineers to:

Use a lot of four-letter acronyms

Design an attractive logo

Attend lots of long meetings

Include models for manufacturing tolerances in components

It is important for engineers to:

Balance the desire for optimality against the practicalities of real-world issues and operational considerations

Optimise every element of each design to make sure the absolute limit of performance is achieved

Understand that “near enough” is most often “good enough”

Multiply the design tolerances by a factor of two, in order to be on the “safe side”

Process Flow Diagrams can:

Show the direction of water in an irrigation system

Both (a) and (b)

Capture the steps and events of a process, and the links and decision points between those events

Graphically represent the links between a set of mathematical equations

Show the direction of electrical current in a circuit

Engineers develop mathematical and computational models for systems:

Based on intuition

Based on the measurements, as well as based on fundamental scientific knowledge and principles

Based solely on measurements

Based on global economic factors

Understanding and modelling randomness is a critical aspect of any engineering design, because:

There is always a degree of uncertainty in any system

If something is not clear in the requirement specification, it may be necessary to randomly make decisions

Unknown physical phenomena may occur at any time

The customer will often change their minds

Engineers approach challenges, problems, and projects, from which perspective:

Simulations and computing perspective

Emotional perspective

Purely financial perspective

Systems perspective

View this question

Engineering system models can include:

All of the other chocies

Mathematical equation-based models

Computer simulation parameterised models

Data-driven learning/neural network models

Hardware prototypes

One of the most basic approaches to fitting models to data sets, is to:

Scale up the data

Use random parameter allocation

Scale down the data

Assume an underlying mathematical model and compare it to the measured data
