Pinewood, Inc., produces two entertainment units for cars (Radio/Satellite/Navigation/Andriod and Apple play with a 10" touchscreen). The entertainment units are identical, but the mounting hardware and finish trim differ. The standard model fits larger sedans and SUVs, and the sports model fits sports cars and smaller cars.

Pinewood handles the production in the following way. The chassis (electronics) is assembled in Quebec 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 South Korean electronics company with offices in Montreal 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 is performed by the customer.

Pinewood 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 the small number of individual sales, are summarized in the following demand schedule:

There are currently 40 chassis units on hand but no trim packages or mounting hardware.

Prepare material requirements to plan to meet the demand schedule exactly. Specify the gross and net requirements, on-hand amounts, and the planned order release and receipt periods for the entertainment chassis, the standard and sports car model trim, and the standard mounting hardware and the sports car mounting hardware.
