Example of decision under certainty : A manufacturer has two different kinds of machines – M1 and M2. 0000007713 00000 n The decision represents a trade-off between the risks and the benefits associated with a particular course of action under conditions of uncertainty. A condition of certainty exists when the decision-maker knows with reasonable certainty what the alternatives are, what conditions are associated with each alternative, and the outcome of each alternative. ����p����N�u&mQ�ͤ#�w�pj��i?��h���߿�g�_d���r��?Y�qB�@�R`q`���㧞xb�FY��6;X��6Hڏ�b����� ���g�檉=��Pl�)�T,�[U�R~xwe�l����*�����b�ev9�&� em$ Most managers prefer to be risk averters to a certain extent, and may thus also forego opportunities.
