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 1 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. 2 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. 4 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. 5 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. 6 The Five Building Blocks (consisting of 18 easy lessons) Block 1 - Algebraic Systems Sets (qualitative models) Algebraic equations and functions Block 2 - Linear Systems Linear equations / inequalities and Matrices Block 3 - Discrete Systems Combinatorics & Discrete Probability Block 4 Nonlinear Systems Differentiation & Optimization Block 5 Stochastic and Dynamic Systems Integration & Differential Equations 7 The 18 Easy Lessons 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Course orientation Methods and Models (An Introduction) Ch 0 Block 1 – Algebraic Systems The Algebra of Sets - Methods Handout Modeling using Sets Algebraic Methods (Equations & Functions) Ch 1.1-1.4, 2, 4, 5.1,5.2 Algebraic Models Block 2 – Linear Systems Linear Methods (Linear Equations and functions) Ch 3.1, 3.2, 3.4 Matrix Methods (General Linear Systems) Ch 6.1 – 6.6 Linear Models (Linear Optimization) Ch 7.1, 7.2 Block 3 – Discrete Systems Methods of Discrete Counting Ch 8.1, 8.2 Sequences & Series Ch 1.5, 5.4 Discrete Probability Models Ch 8.3, 8.4, 9.1 Discrete Models (Optimization) Block 4 – Nonlinear Systems Nonlinear Equation Methods Ch 3.3, 3.5, 3.6 Methods of Differential Calculus Ch 11, 12, 17.1 -17.2 Nonlinear Models (Classical Optimization ) Ch 13, 17.5-17.7 Block 5 –Dynamic and Stochastic Systems Methods of Integral Calculus Ch 14, 15.1 15.3- 15.4, 15.7 Stochastic Models (Continuous Random Ch 16.1 Variables) Differential Equations – Methods and Models Ch 15.5, 15.6 8 Course material For each Block and each lesson, there are Recorded class lectures Adobe Media player Presentation slides Textbook references Problems with solutions In some cases, additional handout material Optional Lab session 9 Prerequisites An undergraduate sequence in calculus y g ( y ) f ( x)dx a L( x, y, ) f ( x, y ) g ( x, y ) 0 x x x 10 Textbook(s) – check the syllabus for the current text Haeussler, Ernest; Richard Paul , & Richard Wood, Introductory Mathematical Analysis, 12th ed., Prentice Hall, Upper Saddle River, NJ, 2008.
