(a)
Interpretation: A machine shop located on the outskirts of Los Angeles accepts custom orders from a number of high-tech firms in southern California. The machine shop consists of four departments: A (lathes), B (drills), C (grinders), and D (sanders). The from-to chart showing distances in feet between department centers is given.

D | 40 | 30 | 68 |
The shop has accepted orders for production of four products: P1, P2, P3 and P4. The routing for production of these products and the weekly production rates are
Product | Routing | Weekly Production |
P1 | A-B-C-D | 200 |
P2 | A-C-D | 600 |
P3 | B-D | 400 |
P4 | B-C-D | 500 |
Assuming that products are produced in batches of size 25; from the given data, a from-to chart giving numbers of materials handling trips per week between departments needs to be given.
Concept Introduction: A routing planning chart consisting of a matrix is called a from-to chart. Various operations are written across the top and along the left side of the form.
