Introduction:

Operations research uses mathematical and computational techniques to improve the efficiency and decision-making of numerous companies and organizations.

Let’s consider the following simplified diet problem as an example. There are two different foods: milk and tomato. The nutritional values of milk and tomato are displayed in Table 1. The objective is to find a minimum calorie diet with milk and tomatoes that contains at least 55 g of protein and not less than 600 mg of calcium. We can model the problem as a linear program and solve it with linear program solvers to obtain a reasonable solution for a diet.

The students in our laboratory study the following areas.

・ Mathematics, including probability, statistics, and optimization, necessary for modeling problems.
・ Computer languages, such as C and Java, for simulations.

Many graduates from our laboratory work in IT and related companies.
