Task:

1. Consider two products, P1 and P2, which need to be produced by three subsequent operations on machines M1, M2, M3. Processing times are given in the table:

a) Calculate lead time for each product individually for the production of the whole batch if part transfer is serial.

b) Calculate lead time for each product individually for the production of whole batch if part transfer is parallel.

c) Calculate lead time for each product individually for the production of whole batch if part transfer is combined.

d) Compare those three methods of part transfer for each product: which generates the longest and which generates the shortest lead time. What is the ratio between the longest and the shortest method and why? Do this analysis for both products.

e) Compare ratios from d) between two products. Are they similar or close? Why?
