Course description and aims

This course introduces probability models and analysis methods on the models to address various phenomenon with uncertainties appropriately. First, the axiomatic probability theory is introduced considering the probability theory that students had already studied at high school. Then, this course formulates random variables and probability distributions. By using these formulations, this course explains how to model various natural and social phenomenon with uncertainties, particularly how to model with the distributions of the linear combination of random variables and the maximum and minimum of random variables. This course also focuses on the stochastic process such as the Poisson process and the Markov process with their applications.

In the analysis of the situation in the management and decision-making, one needs to appropriately address phenomenon with uncertainties. To attain it, it is important to assume a probability model which fits the phenomenon and perform analyses based on the model. This course will provide various models and analysis methods as well as their applications to real problems. Through this course, students will study how to correspond a real problem to a mathematical model and then analyze phenomenon with uncertainties. Some student applications beyond the course will be expected.

(1) Explain the difference between the high school probability and the axiomatic probability.
(2) Understand the random variable, the probability distribution and their applications to real problems.
(3) Explain how the distributions of the linear combination of random variables and the maximum and minimum of random variables are used in real problems.
(4) Understand the Poisson process, the Markov process and their applications.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
