Question

1)      An order has just come in for 1 unit each of SKU1, SKU2, SKU3, SKU4 and SKU5. The picker will start in location O and needs to pick each item before returning to his starting point. The table below represents the distances between locations. If the goal is to minimize distance traveled, in what sequence should he pick the SKU’s, and what is the total distance traveled for the pick? You may use any method discussed to solve this problem. You can do this problem by hand.

Explanation / Answer

This problem is solved using nearest neighbour procedure. It builds the route based only on the distance of traveling from the last-visited node to the closest node in the network.

From the origin the nearest point is SKU1

From SKU1 the nearest point is SKU2 or SKU5

Option 1: Origin -> SKU1 -> SKU2

Option 2: Origin -> SKU1 -> SKU5

From SKU2, nearest point is SKU3. From SKU5 nearest point is SKU4

Option 1: Origin -> SKU1 -> SKU2 ->SKU3

Option 2: Origin -> SKU1 -> SKU5 ->SKU4

From SKU3, nearest point is SKU4; from SKU4 nearest point is SKU2

Option 1: Origin -> SKU1 -> SKU2 ->SKU3 -> SKU4

Option 2: Origin -> SKU1 -> SKU5 ->SKU4 -> SKU2

Developing the route to the origin,

Option 1: Origin -> SKU1 -> SKU2 ->SKU3 -> SKU4 -> SKU5 -> Origin

Option 2: Origin -> SKU1 -> SKU5 ->SKU4 -> SKU2 -> SKU3 -> Origin

Distance Calculation

Option 1: 10+6+6+13+16+16 = 67

Option 2: 10+6+16+7+6+21 = 66

Origin -> SKU1 -> SKU5 ->SKU4 -> SKU2 -> SKU3 -> Origin
