Abstract
The manual method of minimum-time ship routing has
proved so successful over the last several years that
ever increasing numbers of ships" captains are requesting
this service . Hie desirability of the electronic computer
for the computation is therefore readily apparent,, In
this investigation the minimum-time route is determined by
calculus of variations, rather than the conventional manual
technique. The present method consists of solving the
associated Euler equation by numerical integration on the
Control Data Corporation model 1604- digital computer,. In
case 1 the ship's speed is assumed to be primarily a function
of position; and in case 2 the ship's speed is taken to
be a function of its direction as well as position. Case
2 is recommended for operational adaptation.
