- SpikLock makes several lines of metal items. The most recent order has been for 1200 door lock units for an apartment complex developer. The sales and production departments must work together to determine delivery schedules. Each lock unit consists of three components: the knob and faceplate, the actual lock itself, and a set of two keys. Although the processes used in the manufacture of the three components vary, there are three areas where the production manager is concerned about the availability of resources. These three areas, their usage by the three components, and their availability are detailed in the table.

A requires 2 units of D and 1 unit of E. B requires 2 units of E and 1 unit of F. C requires 3 units of D and 2 units of F. Draw the product structure tree. Determine the quantities of the required components for manufacturing 150 units of W.Audio Products, Inc. produces two AM/FM/CD players for cars. The radio/CD units are identical, but the mounting hardware and finish trim differ. The standard model fits intermediate and full-size cars, and the sports model fits small sports cars. Audio Products handles the production in the following way. The chassis (radio/CD unit) is assembled in Mexico and has a manufacturing lead time of two weeks. The mounting hardware is purchased from a sheet steel company and has a three-week lead time. The finish trim is purchased from a Taiwan electronics company with offices in Los Angeles as prepackaged units consisting of knobs and various trim pieces. Trim packages have a two week lead time. Final assembly time may be disregarded because adding the trim package and mounting are performed by the customer. Audio Products supplies wholesalers and retailers, who place specific orders for both models up to eight weeks in advance. These orders, together with enough additional units to satisfy…
