Why do engineers use models?
Models give a visionary view to the problem at hand and help catching all the system aspects.
Example of value engineering in tractors?
Engineering in tractors can easily be seen with all modern tractors basically being seen with 4wd and a cab with air conditioning. The best way to track engineering is through the John Deere Combine. In the sixties it was all manualy adjusted then seventies some adjustments were moved to the cab. Eighties more adjustments were moved into the cab but you still had to moniter the dirt in the grain and how much grain was being lost. The nineties brought sensors tracking the amount of grain lost and it can be adjusted in the cab. The newest models have sensors and adjustments all connected to a computer and the computer tracks grain loss and makes adjustments without operator imput.
What simple machines are used in a wheelchair?
A wheel and axle is standard to all models. If it's motorized, then there's probably also a lever to make it go.
What is the importance of system modelling?
Models help us to visualize a system as it is or as we want it to be.Models permit us to specify the structure or behavior of a system.Models give us a template that guides us in constructing a system.Models document the decisions we have made.
What is home interview survey in transportation engineering?
Transportation forecasting is the process of estimating the number of vehicles or travelers that will use a specific transportation facility in the future. A forecast estimates, for instance, the number of vehicles on a planned freeway or bridge, the ridership on a railway line, the number of passengers patronizing an airport, or the number of ships calling on a seaport. Traffic forecasting begins with the collection of data on current traffic. Together with data on population, employment, trip rates, travel costs, etc., traffic data are used to develop a traffic demand model. Feeding data on future population, employment, etc. into the model results in output for future traffic, typically estimated for each segment of the transportation infrastructure in question, e.g., each roadway segment or each railway station.Four-step models Within the rational planning framework, transportation forecasts have traditionally followed the sequential four-step model or urban transportation planning (UTP) procedure, first implemented on mainframe computers in the 1950s at the Detroit Area Transportation Study and Chicago Area Transportation Study (CATS). Precursor steps Although not identified as steps in the UTP process, a lot of data gathering is involved in the UTP analysis process. Census and land use data are obtained, and there are home interview surveys. Home interview surveys, land use data, and special trip attraction surveys provide the information on which the UTP analysis tools are exercised.Source: WikipediaRefer to links to read the article
Which types of models are built with assumptions?
b
Why do economists make assumptions while developing models?
The economists make assumptions while developing models because they are taken into consideration what the scenario would look like say after 10 years.However these assumptions are not hypothetical and are based on intricate mathematical calculations.The assumptions are important since the models cannot be developed without taking into consideration the future aspect.
Why do models have limitations?
Models have limitations due to the fact that they are the real representation of the earth. Most of the scientific models are based on assumptions.
What models are mathematical models of the master budget that can react to any set of assumptions about sales costs and product mix?
Financial Planning Models
What are the components of nursing theory?
The components of nursing theory typically include concepts, definitions, assumptions, and propositions. Concepts are the building blocks of theory, definitions provide clarity, assumptions outline beliefs about the phenomena being studied, and propositions communicate the relationships between concepts.
What types of computer models were used to develop climate models?
Computer models weren't used. Real computers were used.
Do economic models always accurately predict economic behavior?
No, economic models don't always predict economic behavior because models are based on assumptions, or things that we take for granted as true.
What are the three types of of models?
the three types of models are physical models,idea models and computer models.
Criticism to Economic order quantity?
The assumptions included in the EOQ models are simplistic;The real cost of stock in operations are not as assumed in EOQ models;The models are really descriptive and should not be used as prescriptive devices.
What does ECM mean?
ECM stands for "Engine Control Module" and is the generic term for the computer that controls engine functions. On some models, this same computer also controls the transmission, and is referred to as the "PCM" or "Powertrain Control Module".
What is the similarity between computer models and physical models?
They are both models, andthey both can be explained.
How many people around the world use tiger computers?
There is no brand of computer made that is called "tiger". Furthermore there are no models of either laptop or desktop that has been referred to as "tiger".
