I'm trying to put 2 equations in 1 and get the summation indices in the right place. My code is:
\begin{equation}
\left
\begin{array}{c}
\sum_{s \in S} \sum_{e \in E} \sum_{p \in P}
X_{i}_{e}_{p}_{d}_{s} \ge 1 \\ \\
\sum_{s \in S} \sum_{e \in E} \sum_{p \in P}
X_{i}_{e}_{p}_{d+1}_{s} \ge 1
\end{array}
\right \} \Rightarrow W_{i}_{d} = 1
\end{equation}
How can I fix this?
