Question

Consider the following information regarding a bicycle (e.g., Road Bike). Each finished bicycle requires 1 set of handlebars, 1 frame assembly, and 1 seat. In turn, 1 frame assembly requires 2 wheels and 1 frame. At the next level, 1 wheel is produced from 12 spokes and 1 tire rim, and 1 frame requires 5 feet of aluminum tubing and 1 gallon of paint.

1. Develop product structure tree for Bicycle.

2. How many spokes are required to manufacturer 20 Bicycles; given that you already have 10 finished frame assemblies on hand

Answer 1

Please find below the product structure:

2. Number of bicycles need to be made = 20

Number of frame assemblies required = 20*1

Frame assemblies at hand = 10

Net requirement of Frame assemblies = 20 - 10 = 10

Number of wheels required = 2*10 = 20

Hence, Number of spokes required = 12*20 = 240 spokes

So, we need 240 spokes to make 20 bicycles when 10 frame assemblies are on hand.
