Continuous-Time Grey Exogenous Models

In Chapter 3 and Chapter 4 , we presented the continuous and discrete forms of grey endogenous models without considering the influence of external variables. This chapter will incorporate exogenous variables from the outside of the system and employ ordinary differential equations to describe dynamic systems affected by exogenous variables. We will focus on investigating continuous-time grey exogenous models, using the GM(1, N) model and multi-input and output MGM(1, N) model as typical examples.
