Aneetings must be scheduled after $8am$ the following Monday.

$2.$ A meeting $m_i$ may start before or after $-$ its suggested start time $s(m_i),$ but the duration of $m_i,d(m_1)=f_i(m_i)-s_i(m_i)$ cannot change.

$3.$ Suppose, $S_i(m_i)$ and $F_i(m_i)$ are the start and the finish times of $m_i$ in the SCHEDULE respectively $($they may be different from $s(m_i)$ and $($:$f(m_i)\}.$ The delay of $m_i$ in the SCHEDULE is $D_i=$max$(0,S_i-s_i)($so if $s(m_i)=3pm,$ but it is scheduled for $S_i=5pm,$ then the delay $D_i=5-3=2($hours$).$ If $s(m_i)=2pm,$ but it is scheduled for $S_i=1pm,$ the delay $D_i=0).$ The maximum delay is $D=$max$(D_i),$ so if $D_1=1,D_2=0$ and $D_3=4,$ then max$(D_i)=D_3=4$
