contents This contribution considers the time-fractional subdiffusion with a time-dependent variable-order fractional operator of order $β(t)$. It is assumed that $β(t)$ is a piecewise constant function with a finite number of jumps. A proof technique based on the Fourier method and results from constant-order fractional subdiffusion equations has been designed. This novel approach results in the well-posedness of the problem.
