The figure below shows the Bill of Materials buildup to 2 finished products of bicycle rack manufacturer Hang Up (HU). For example, Product 2 uses one Assembly 3 and four Part 6’s.

Each Assembly 3, in turn, is made up of 2 Part 5’s and 1 Part 7. All Products, Assemblies and Parts are produced at HU’s plant. 

Using decision variables xj Ú 0, j = 1,c, 7 for the numbers of objects j (Products, Assemblies, or Parts) produced per week, formulate all material balance constraints required in an LP to assure enough of each object has been manufactured to meet given weekly demands d1 and d2 for finished products 1 and 2.
