Objectives

The course seeks to introduce several key analytical methods and tools useful in the analysis of productive systems (in manufacturing and services). At the end of the course, students should be able to:
- Correctly analyze  queueing systems (with and without limitations of capacity and population),

-Apply several productive network analysis techniques properly

- Properly formulate and solve production problems through dynamic programming

- Design scenarios and future behaviors with Markov chains

Prerequisites

Is advised that students have some expertise in Statistics and Operations Research

Subject matter

1.Queueing Theory: Basic Structures; Terminology and Notation; Main Performance Measures; Little’s Equations; Deterministic and Probabilistic Models with Exponential distributions and FIFO discipline; Multiple-server;  Finite queue and finite calling population variation; Data Analysis and Goodness Fit Tests

2.Graphs and Network Analysis: Minimum Spanning Tree; Shortest-Path; Maximum Flow; Transportation;   Assignment and Transshipment Problems

3.Dynamic Programming: Graph Formulation; Main Characteristics; Contributions Types: additive, multiplicative, additive-multiplicative, max-min e min-max; Applications

4.Introduction to Markov Chains: State Characterization and classification; Transition Matrix;    Steady-State Conditions; Applications
