Question: Solve Problem, except use the lower-bound approach in your analysis, in which the part is removed every time a breakdown COCCUS Determine:

(a) how many starting workparts would be required to produce the 2000 units.

(b) line uptime efficiency, and

(c) how many hours were required to produce the 2000 parts.

Problem: An eight-station rotary indexing machine performs the machining operations shown in the accompanying table, together with processing times and breakdown frequencies for each station. The transfer time for the machine is 0.15 min/cycle. A study of the system was undertaken, during which time MX/parts were completed. It was determined in this study that when breakdowns occur, it takes an average of 7.0 min to make repairs and get the system operating again. Assume the upper-bound approach is applicable. For the study period, determine:

(a) average actual production rate,

(b) line uptime efficiency, and

(c) how many hours were required to produce the 2000 parts.
