**PLEASE DO QUESTION 12** Thank you!

12) Repeat the previous problem using a POQ strategy where the natural cycle for U-bars is three weeks and for all other parts, the cycle is two weeks.

THE PREVIOUS PROBLEM: A company produces combination locks for household use on gates, lockers, and so on. The general parts structure and lead time is shown in Figure 8.3. For one particular model, the MPS calls for assembling 0, 500, 300, 300, and 400 in the next six weeks, respectively. Currently, there are 140 metal bodies, 230 U-bars, 600 lock assemblies, and 347 turn knobs on hand. An open-shop order for 700 locking mechanisms are due to be received at the start of week 2. Using a lot-for-lot decision rule, plan order releases for each item over the horizon.
