The search for a set of journeys that is optimal for a firm of extra urban road transports is carried out, due to the variety of several intervening constraints, by means of an exhaustive procedure. The time table of the scheduled journeys, and also the unscheduled ones that are possible are represented as a phase structured grammar: every possible journey is determined through a special syntactical analyzer of the languages generated by this grammar. Among the solutions, all compatible with trade union rules and with constraints-and-desiderata of the management, those realizing the minimal cost are selected by means of linear programming techniques.
