According to Collins
5. Your approach to a task, problem, or situation is the way you deal with it or think about it.

So in Bangla, we can say

Our approach to solution of the problem=
সমস্যা সমাধানে আমাদের পন্থা
somashsha somadhane amader pontha (a way of dealing with sb/sth)
সমস্যা সমাধানে আমাদের দৃষ্টিভঙ্গি
somashsha somadhane amader drishtibhongi (a way of thinking about sth such as a problem or a task)

Other options are
সংকট নিরসনে আমাদের কর্মপন্থা/কর্মধারা/কর্মকৌশল
sankat nirosone amader karmapontha/karmadhara/karmakoushal
