The lead time required to purchase or produce (from its immediately lower components)

each component of the 16-mm equalizer is shown in parentheses below the component on the product structure tree that follows. How many components should be ordered, and when should they be ordered or started into each production operation, so that the company will complete 400 equalizers in week 10 (10 weeks in the future)? Disregard scrap allowances or any equalizers or components that are already on hand.
