Please help me out with Question e. I'm not sure. Thanks

An auto part manufacturer has been attempting to convert its operations to practices more in keeping with JIT principles. The firm is now paying much more attention to the transit time between one processing stage and the next. The plant has a somewhat haphazard pattern of machine locations, partly because the machines were purchased and installed at different times, partly from a shortage of floor space, and partly from previous experiments with work cells. The bottom line is this: there are four machines that perform a certain processing phase, and three machines that perform the next phase. All units of a large class of cars go through these two phases. The table below displays the transit time, in minutes, from each machine of the first phase (P1) to each machine of the second (P2). Mach 3 is not really 95 minutes away from machine B, but the company has prohibited that combination because of quality ulvugI uICse ivvu pilases. The table below displays the transit time, in minutes, from each machine of the first phase (P1) to each machine of the second (P2). Mach 3 is not really 95 minutes away from machine B, but the company has prohibited that combination because of quality problems associated with that specific pairing (so the 95 is entered into the problem). Supply and demand quantities are in cars processed per week. Develop a transit time minimizing solution for this firm. a. What is the least transit time of this solution? b. Which machine in Phase 2 did not meet its required demand? c. Which machine in Phase 1 has some capacity unused? d. Was the prohibition on the Mach 3 Mach B combination honored? e. What if you now require 75 units to be shipped from Mach 4 to Mach A. What is the optimal solution
