Your Initials 2. A total of 5000 mechanical subassemblies are needed annually on a final assembly line. The subassemblies can be obtained in one of three ways: (1) Make them in one of three plants owned by the company; (2) buy them off the shelf from the one and only manufacturer; or (3) contract to have them made to specifications by a vendor. The estimated annual cost for each alternative is dependent upon specific eircumstances of the plant, manufacturer, or contractor. The information shown in the table below details the eircumstance, a probability of occurrence, and the estimated annual cost. Costruet a decision tree, then determine the best alternative by calculating the expected cost of each alternative and selecting the least cost alternative.
