Engineering Analyses – Methods
and Models (ENM 503)
Lesson 0 - Course Introduction
A preliminary course in the mathematical
methods and models used in the formulation
and solution of problems found in engineering
management and operations research
Narrator: Charles Ebeling

Course Description




The necessary foundation in mathematics to complete
successfully the ENM and MSC core courses in probability
and statistics and operations research as well as the
quantitative elective program.
The mathematical techniques presented are motivated by
their use in solving real-world problems.
Not a concept-theory course but rather a course designed
to enhance your mathematical modeling and solution
method skills.
The models discussed have proven to be the most
useful and successful constructs in solving operations
research and engineering management problems.

Who should take this course?
Those that have not previously studied in any depth or may have studied but
have forgotten nor never quite mastered the following:








Set notation and set theory
Systems of linear equations and inequalities
Linear algebra (vectors and matrices)
Discrete mathematics (combinatorics)
Why didn’t I take the
Nonlinear systems of equations
503 course?
Differential and Integral Calculus
Classical optimization
Differential equations
3
Course Objective
To be able to mathematically model engineering
management and management science problems and
to manipulate these models using the methods of
engineering, operations research, economics,
mathematics, computer science, probability and
statistics, and any other discipline or technique that
will solve the problem at hand.
Gosh, this is a
really great
objective.

Specific Objectives






Apply symbolic logic and set theory, Cartesian
graphs, and functions to describe real world
problems,
Formulate and solve algebraic models,
Use matrix algebra to define and solve linear
systems,
Find discrete solutions using counting methods,
random events, and discrete optimization,
Apply differential calculus to describe,
approximate, and optimize nonlinear functions, and
Use integral calculus to model stochastic
processes and dynamic systems.

Methods and Models
The topics covered…
 May be well known to you
 May be something you once knew but forgot
 May be completely new to you
For the typical student, it is
very likely that all three
cases will be encountered.
