(8) Going forward, if it is found to be a better decision to make the components in-house, DBS will then need to select an optimal location point to set up its manufacturing facility.

Given the following location information and expected material movements from several transportation depots to the DBS intended manufacturing facility, find and plot the best location using centre-of-gravity method:

Transportation depots	x	Y	Expected material movements (no. of units)
1	16	15	22000
2	5	13	15000
3	10	11	5400
4	6	5	8000
5	12	6	11500
6	18	8	10000
