The purpose of this study is to find out the export and import turnover of Vietnam in the future time when Vietnam joins as a part in the transactions of exchanging goods with other countries all over the world. The valuation of transporting products in the future from 2020 to 2023 will be predicted by grey forecasting method with the GM (1,1) model which bases on the historical time series during the period of 2012 to 2019.

Greying of the hair is an obvious sign of human aging. In addition to age, sex- and ancestry-specific patterns of hair greying are also observed and the progression of greying may be affected by environmental factors.

This study improves the first-order and one-variable grey differential equation model (abbreviated as GM(1,1) model), which requires only a limited amount of data to estimate the behavior of a system with unknown and known information, to predict road traffic fatalities (RTFs) in Hanoi in short-term with experimental data of RTFs from 2010 to 2018.

A finite element analysis is performed for the bolted joint and the model is used to predict stress field for a Grey Cast iron and aluminum alloy. Joint member stiffness is presented against member aspect ratio in dimensionless form. Results show good agreement as compared with those of used techniques of Montosh and Marschke.

The green growth prediction plays an important role to assess and monitor the growth rate of a local region. Managers and researchers can make timely adaptation policy to improve and innovate economic, cultural and environmental performance to impulse the green growth. The study used the methods such as the multiple criteria analysis, analytic hierarchy process, principal component analysis, and the grey theory model to build and integrate green growth indicators into the green growth index.
