Résumé

The present paper deals with the problem of pursuit of a group of rigidly coordinated evaders in a nonstationary conflict-controlled process with equal opportunities $$ \begin{array}{llllllllcccc} P_i\dot x_i=A(t)x_i+u_i, u_i\in U(t), x_i(t_0)=X_i^0, i=1,2,\dots,n,\\ E_j\dot y_j=A(t)y_j+v, v\in U(t), y_j(t_0)=Y_j^0, j=1,2,\dots,m.\\ \end{array} $$ We say that a multiple capture in the problem of pursuit holds if the specified number of pursuers catch evaders, possibly at different times $$ x_\alpha(\tau_\alpha)=y_{j_\alpha}(\tau_\alpha),\quad\alpha\in\Lambda,\quad\Lambda\subset\{1,2,\dots,n\},\quad|\Lambda|=b\quad(n\geqslant b\geqslant 1),\quad j_\alpha\subset\{1,2,\dots,m\}. $$ The problem of nonstrict simultaneous multiple capture requires that capture moments coincide $$ x_\alpha (\tau)=y_{j_\alpha}(\tau),\quad\alpha\in\Lambda. $$ The problem of a simultaneous multiple capture requires that lowest capture moments coincide $$ x_\alpha(\tau)=y_{j_\alpha}(\tau),\quad x_\alpha(s)\ne y_{j_\alpha}(s),\quad s\in[t_0, \tau),\quad\alpha\in\Lambda. $$ In this paper we obtain necessary and sufficient conditions for simultaneous multiple capture and nonstrict simultaneous multiple capture.
