TEXTBOOK: ·Engineering
Cost Estimating by Phillip F. Ostwald, Prentice-Hall, 3th Edition.
· Interest Tables
CLASS:
Spring Semester 1999
Monday - Wednesday - Friday
12:00 m. – 12:50 pm.
EGR A 111
OBJECTIVE:
The purpose of this course is to provide the student
with a comprehensive coverage of the latest principles and techniques for
the economic evaluation of a project and their applications in capital
budgeting, as well as to develop the ability of the student to prepare
accurate cost estimates and systematically allocate them and control them
in manufacturing environments.
REQUIREMENTS:
Major emphasis will be placed on reading and understanding
the material from the class, suggested books and reference material prior
to class, and in homework assigned. I do require class attendance.
GRADES:
·4 Examinations, each
of which counts 20% of your grade.
·Homework, Team Projects,
and Quizzes which count 20% of your grade.
STANDARDS:
Letter grades are assigned based on the total number
of points accumulated.
·A : 90% and higher
·B : 80% - 89.99%
·C : 70% - 79.99%
·D : 60% - 69.99%
·F : Less than 60%
GRADING POLICY:
Missed examinations and assignments have a 10% penalty
per day, imposed when turned in, unless an appropriate, prior excuse is
provided to the instructor. The missed examination must be completed on
the make-up date set by the instructor.
ACADEMIC CONDUCT:
Cheating on examinations, submitting work of other students
as your own, or plagiarism in any form will result in penalties ranging
from an F on the assignment to expulsion from the university, depending
on the seriousness of the offense.
OFFICE HOURS:
10:00 a.m. to 12:00 p.m. Monday, Wednesday & Friday;
other hours by appointment.
EQUIPMENT AND SOFTWARE:
Hand-held calculator and any computer-based spreadsheet.
Excel is available in all the P.C. laboratories in Engineering including
Industrial Technology labs. and College of Engineering labs.
