02 Cultural understanding and exchanges

Beijing has a history of over 3,000 years with

a population of nearly 13 million and a lot of

places of interest around it. In recent years,

the city of Beijing has been advancing very

quickly. You can see many museums, parks

an shopping centers here and there. More

and more highways and overhead walkways

have been built up. What's more, a lot more

buses which burn cleaner fuel, such as CNG

or LPG, are put into use, to prevent air from

being polluted.

03 My major

My major: Industrial Engineering

Industrial Engineering is concerned with the design,

improvement, and installation of integrated systems of

people, materials, information, equipment, and

energy. It draws upon specialized knowledge and skill in the

mathematical, physical, and social sciences together with the

principles and methods of engineering analysis and design to

specify, predict, and evaluate the results to be obtained

from such systems.

Production and Operations Analysis

Genetic algorithm for the Flexible Job-shop Scheduling Problem

The Flexible Job-shop Scheduling problem (FJSP) is a

generalization of the classical JSP, where operations are allowed

to be processed on any among a set of available machines. Then,

FJSP is more difficult than the classical JSP, since it introduces a

further decision level beside the sequencing one, i.e., the job

routes. To determine the job routes means to decide, for each

operation, what machine must process it, among the available

ones.

Measurement and simulation of Classroom Lighting

Using the DIAlux software to simulate the scene of the classroom

of artificial lighting. The image of the desktop, blackboard and

ground, the pseudo color map, the distribution table and the

simulation rendering effect of the 3D lighting are obtained. The

results are compared with the actual measurement results.
