Several methods exist to measure $CP$ violation observables related to theCKM unitarity triangle angle $\gamma$ using $B$ meson decays. These observablesare different for every $B$ meson decay considered, although the informationthey contain on $\gamma$ is encoded in a similar way for all of them. Thispaper describes a strategy for a simultaneous measurement of $\gamma$ usingseveral $B$ meson decays that takes into account possible correlations betweenthem. Sensitivity studies demonstrate that the simultaneous analysis of several$B$ meson decay modes results in smaller uncertainties and improved statisticalbehaviour compared to a combination of standalone measurements.
