I have the following constraints and am wondering whether I can formulate the whole thing more narrowly and with fewer constraints. $x_{itk}$ is binary and $u_{it}, v_{itk}\in [0,1]$. $M$ is a Big-M constant. These are my constraints.
\begin{align} &v_{itk} \geq u_{it} - M\cdot (1-x_{itk})& \forall i \in I, t\in T, k\in K \\ &v_{itk} \leq u_{it} + M\cdot (1-x_{itk})& \forall i \in I, t\in T, k\in K\\ &v_{itk} \leq x_{itk}& \forall i \in I, t\in T, k\in K \end{align}
