Question

(Setup Everywhere) Consider the follow batch-flow process consisting of three process steps performed by three machines: STEP 1 STEP 2 STEP 3 Processing TIme: Processing TIme: Processing TIme: 0.25 Minute/Part 0.20 Minute/Part 0.15 Minute/Part Setup Time: Setup Time: Setup Time: 30 minutes 20 minutes 45 minutes Work is processed in batches at each step. Before a batch is processed at a step, the machine at that step must be set up. (During a setup, the machine is unable to process any product.) Assume that there is a dedicated setup operator for each machine (i.e., there is always someone available to perform a setup at each machine.) a. What is the capacity of step 1 if the batch size is 35 parts? b. For what batch sizes is step 1 (2,3) the bottleneck?

Explanation / Answer

a. 30+20+45+.20*35+.15*35+0.25*35=116 min. is required for 35 parts of ach step!

and capacity of step 1 is 21


b.for 4 such batch, the step 1,(2,3) is a botleneck!
