We examine various aspects of supersymmetric particle production at linear {ital e}{sup +}{ital e}{sup {minus}} colliders operating at a center-of-mass energy of {radical}{ital s}=500 GeV, and integrated luminosity of {integral}L{ital dt}=20{minus}50 fb{sup {minus}1}. Working within the framework of the minimal supergravity model with gauge-coupling unification and radiative electroweak symmetry breaking (SUGRA), we study various signatures for detection of sparticles, taking into account their cascade decays, and map out the regions of parameter space where these are observable. We also examine strategies to isolate different SUSY processes from each other. In addition, we perform four detailed SUGRA case studies and examine the detectability of sparticles when several SUSY processes are occuring simultaneously. We show that precision mass measurements of neutralinos, sneutrinos, and top squarks are possible, in addition to previously studied precision mass measurements of sleptons and charginos. {copyright} {ital 1996 The American Physical Society.}
