Assume that there is a requirement for a new system with a specified performance capability and a reliability of 70%. In response to an "invitation to bid," three supplier configurations have been proposed and are reflected in the diagrams below. Configuration A B c F E H A K M N P L Configuration B N 0 K F G A B D L H E M
Configuration C H B C M А D E N F G K The competent reliability factors are noted in the following table: Component Reliability Component Reliability Component Reliability A 0.84 G 0.87 M 0.83 B 0.86 H 0.88 N 0.85 с 0.89 1 0.89 0 0.84 D 0.86 J 0.86 P 0.89 E 0.87 K 0.85 Q 0.89 F 0.82 L 0.86 The overall cost associated with each of the supplier proposals is R57,000 for Configuration A, R39,000 for Configuration B, and R42,000 for Configuration C. a) Determine the system reliability for each of the three configurations. [15] b) In evaluating the three alternatives, employing cost-effectiveness (CE) criteria, which configuration would you select as being preferred? [4]
