The schedule of the optimal solution for the example problem (5 products to be processed in 2 stages) is shown in Figure 1.

In the optimal solution the production of product C tends to be high since it is the most valuable product. Also the production of C in the 2 stages is almost simultaneous in order to reduce intermediate inventory levels.

  • The number below the line indicate the product and the number above it indicates its processing time.

  • The boxes show the transition times between the processing of two products
