Mathematical analysis on troubleshooting problem during COVID-19 pandemic

Abstract

Mathematics is closely related to people's daily lives, such as the various shapes that can be seen everywhere, and the various distance relationships. Similarly, industrial production is inseparable from mathematics. The problem of nesting is a representative planning problem in industry and is widely used in the fields of construction, clothing, machinery and wood. With the development of computers, the nesting problem has been significantly improved by relying on the emergence of some intelligent algorithms. However, at the beginning of the problem, establishing a reasonable mathematical model is an essential step. This article summarizes thecommon mathematical models in the troubleshooting problem and analyzesthe advantages and disadvantages during COVID-19 pandemic.
