Dr. Lyle N. Long
Computational Science, and
Certified Master Software Engineer (IEEE Computer Society)
The Pennsylvania State University
This course is an introduction to software engineering.
Software engineering includes
all aspects of professional software production, and is
especially important for
safety-critical and mission-critical software. It is also
crucial for very large complicated software projects. It includes
processes, requirements, design models, computer programs,
validation, verification, cost estimation, management,
and other aspects of the development process. Aerospace
systems, including aircraft,
spacecraft, onboard avionics, ground-based systems, flight
simulators, and air
transportation systems, rely heavily on software. Software
is a major cost of all
aerospace systems. For example, the Boeing 777 has more
than 1000 onboard processors
and more than 4 million lines of software, which is
primarily written in Ada. The
F/A-22 fighter has more than 2 million lines of software
onboard, and much of this
is Ada also. The AirBus 380 has
500 kilometers (311 miles) of wire. Aerospace systems also demand a level of
reliability far beyond most
other systems, which means the software must be designed
using rigorous mission-critical
and safety-critical procedures, which makes the software
quite unique compared to most other
software. Software and computing accountd for about 70%
of the cost of the F-35 The FAA and DOD are both involved in certifying
aircraft software, for example
through the DO-178C and DOD-2168 standards.
Aerospace job openings are mainly in the area of software, computing, and
systems; as shown in this slide.
This course will help you enormously.
The students will learn the fundamental components of software engineering,
and how complex software systems are developed so as to minimize errors and
maximize the usefulness of the software. They will also learn the terminology,
accepted practices, and procedures used in software engineering. You will also have a basic understanding of systems engineering, since software engineering is really systems engineering applied to software development.
There will also be a software engineering project in the course,
and the students will work in teams on this. We are still working
out the details of what the project will be. Also, students will need to
purchase some equipment for the project (e.g. Beaglebone boards, books, sensors, ...), but the cost will be minimal.
Students who successfully complete this course will be able to:
- Explain the importance of safety-, mission-, business-,
and security-critical systems;
- Demonstrate knowledge of the importance of good software
engineering practices for critical systems;
- Describe and explain the terminology, accepted practices,
and procedures used in software engineering;
- Explain the differences among software engineering, computer
science and systems engineering;
- Decide which computer languages are well suited to modern
critical systems (and explain why);
- Explain a variety of life-cycle models;
- Read and demonstrate an understanding of the software
engineering literature; and
- Demonstrate a basic understanding of the existing
standards (e.g. FAA and IEEE) applicable to software systems
Software engineering for safety-
and mission-critical systems,
including requirements, management, processes, designs,
and other aspects of software development. 3 Credits.
Prerequisite CmpSc 201C (and/or AERSP 424)
( ? Lectures ):
Detailed course notes:
You will all need to read these thoroughly.
All the material in these documents, course notes,
and my lectures WILL be on the exams.
Other good books:
"Software Engineering," 8th Edition, by Ian Sommerville
- Mission- and Safety-Critical Systems
- Requirements Engineering
- Software Design (Object oriented, real-time, ...)
- Computer Languages (Ada, C++, and Java)
- Software Development, ReUse, and Evolution
- Verification, Validation, and Testing
- Project Management
- Software Cost Estimation
- Software Standards
- Emerging Technologies
The slides are on the web, but that does not mean you do not
need to come to class. You need to hear what I have to say
about the slides. Also, you will need to read the book and other
materials, simply coming to class will not be enough.
And you need to take notes! Get a notebook and bring it to class every day.
There is no way you can remember what I say from one class to the other, and
especially to the exam time. If you do not have pen and paper in front
of you during class, I will assume you are not taking the course
seriously. (you could also print out the slides before class
and mark them up as I talk)
The students will be evaluated using a combination
of homework assignments, team projects, and
exams. There will be no final exam. The weight given to each
will be roughly:
The instructor will
use a standard technology-based
classroom. There may also be team-based assignments,
and team presentations.
The course will be offered every year.
- 5% Class Participation
- 35% team project (e.g. group presentations, reports, final test, ...)
- 5%, "what is" group presentation
- 5%, group presentation
- 5%, Report
- 10%, peer grades
CEO grades CFO and CIO, CFO and CIO grade group leaders, group leaders grade group members
- 10% , Final Test and Competition
- 60% exams (three, 20% each)
- 3% Extra Credit for
- winning project competition (equivalent to 20% increase on an exam)
- CEO, CFO, and CIO if jobs well done
- Members of software team, if they contribute
You can compute your Final Grades using this table:
- A: 94-103
- A-: 90-93
- B+: 87-89
- B: 83-86
- B-: 80-82
- C+: 75-79
- C: 60-74
- D: 40-59
- F: <40
Academic Integrity: Faculty Senate Rule 49-20 states, in part, "Academic integrity is the pursuit of scholarly activity free from fraud and deception and is an educational objective of this institution." Faculty are required to clarify the application of this rule to each course:
I encourage you to study together and to discuss ideas for your projects, but the work that you hand in must be your own. Don't cheat: the specified penalties (see Policies and Rules for Students) are not worth it. At a minimum, assignments or exams that show evidence of cheating will be given zero credit. At the other extreme, you may be given an F in the course, or be reported for disciplinary action.
Note the important line in the
Penn State song:
"May no act of ours bring shame To one heart that loves thy name,"
Students auditing the course for credit will be required to
take the exams, and get a C or better.
Also, I don't allow people to simply sit in on the course.
You will need to read and study
all webpage notes also check the
homework webpage regularly.
We gratefully acknowledge the
Leonhard Center for funding to help
develop this course.
Please, please, please:
- Be on time for class
- Turn off your cell phones (if your phone rings, you have to buy cookies for entire class)
- Don't talk during lecture
- And take notes!
You must have taken a course in computer programming (e.g. CS 201),
but it would be very valuable to have a more advanced course as well
(e.g. AERSP 424 ).
Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities.
