1.1 What is a system? Give an example that fits your definition of a system. (Hint: Provide a system example that is appropriate for being designed using the systems engineering process, as you will need to refer back to your selected system in several subsequent questions).
What is systems thinking? Consider the system you selected previously at question 1.1 and discuss the value of systems thinking process if it were to be applied to your selected system.
1.3. Which of the following is not a systems science discipline?
1.4. Define the lifecycle for a system. Draw the stages of a system’s lifecycle. Discuss the lifecycle characteristics for the system you selected at question 1.1.
1.5. What is the difference that systems engineering makes between system primary functions and system secondary functions? Identify the system primary function(s) and system secondary functions for the system you selected at question 1.1.
1.6. In which systems engineering process stage is the largest commitment to technology, performance, and cost made?
1.7. Provide two examples of system specifications for the system you selected in question 1.1.
1.8. In which systems engineering process stage is the requirements development process started?
1.9. What are the design dependent parameters (DDPs)? What are the design independent
parameters (DIPs)? Consider again the system you selected at question 1.1, and give two examples
of DDPs and two examples of DIPs.
1.10. Define Domain Requirements and Non-Functional Requirements. Provide an example of
each for the system selected in question 1.1.
1.11. What is meant by “true” testing and in which stage of the systems engineering process is the
“true” test performed? Considering again the system you selected at question 1.1, briefly describe
how you would have the “true” test performed?
1.12 A system (vehicle) main function is to transport a group of students from city A to city B on
Florida’s turnpike (a toll road). The vehicle is equipped with a SunPass device (a prepaid toll
program) and such it does not need to stop at any of the toll plazas on route from city A to city B.
With regard to the system main function, in which of the following categories would you include
the SunPass device?
Question 2 (10 × 3 = 30 pts.): Answer the following requirements development questions.
2.1 Consider the following statements and choose the correct answer.
2.1.1 The objective of the verification process is to “build the system right.” What does that
mean?
2.1.2 The objective of the validation process is to “build the right system.” What does that
mean?
2.2 Consider the following requirements and choose the correct answer. Provide short answers, if
your selected answer asks for that.
2.2.1 The probability of receiving an incorrect bit on the telecommunications channel shall be
less than 0.001.
verified through testing, propose another means of verification.
2.2.2 The probability of loss of life on a manned mission to Mars shall be less than 0.001.
verified through testing, propose another means of verification.
2.2.3 The probability of the system being canceled by politicians shall be less than 0.001.
cannot be verified through testing, propose another means of verification.
2.2.4 The system shall be available 99.9% of the time.
2.3 The following text is used for questions 2.3.1 – 2.3.4: Consider the following set of
requirements for an electric water heater controller and chose the correct answer. Provide short
answers, if your selected answer asks for that.
shall output 3000 Watts.
shall output 2000 Watts.
shall output 1000 Watts.
2.3.1
a) The set of requirements is correct.
b) The set of requirements is incorrect. If the set of requirements is incorrect, identify
the condition, status, reason, or piece of information that makes the set of
requirements incorrect.
2.3.2
a) The set of requirements is unambiguous.
b) The set of requirements is ambiguous. If the set of requirements is ambiguous,
identify the condition, status, reason, or piece of information that makes the set of
requirements ambiguous.
2.3.3
a) The set of requirements is complete.
b) The set of requirements is incomplete. If the set of requirements is incomplete,
identify the condition, status, reason, or piece of information that makes the set of
requirements incomplete.
2.3.4
identify the condition, status, reason, or piece of information that makes the set of
requirements inconsistent.
Question 4 (40 pts.):
You are assisting a firm during the conceptual design process for a new system designed to
automate the food production for a senior living facility. The new system must perform the
following functions
Create a Morph Chart to explore different potential solutions for this design challenge.
Question 5 (60 pts.):
Three requirements elicitation techniques (Designer as Apprentice, Task Analysis, and Interviews)
were used to obtain the process of designing and bringing new products in an assemble-to-stock
company that produces components for aircraft systems described below:
The first step is to design the product, based upon marketing data and engineering data. This must
be done for no more than X $. Once the product is designed, the assembly plan is generated.
Facility data is used to ensure that the assembly plan is feasible. Three months are available for
designing the product and developing the assembly plan.
The assembly line is then designed. This consists of three steps as follows:
and the product design. Facility data and equipment catalogs are also used for this step.
assignments, number of stations, and facility data.
Once these steps have been completed, the assembly line design, along with the required monthly
production quantity and some labor loading data, are used to determine the production plan.
Finally, the production plan and product design data are used to determine suitable inventory
control policies for the assembly line. The product design, assembly plan, assembly line design,
production plan, and inventory control policies are all used as inputs to other planning activities.
Develop an IDEF0 model for this process. Your model should consist of informational activities
only, and no mechanisms need be presented.
