Web2) We combined grey system GM (1, 1) forecast model and Markov chain to supply a new way to understand the characteristic of gas emission. Its advantage is the historical data can be fully used, and weakening many uncertain factors. So it can extend the application of grey system prediction and Markov chain prediction. WebGrey-Markov chain model analysis is to measure the degree of relevance between factors according to the degree of similarity or difference in the development of factors and is a …
