. Determine the best design for the Telematics Device from the three different options A, B and C presented below. Utilize the Analytic Hierarchy Process (AHP). Show your calculations to three decimals in each step.

The characteristics of the device that are relevant for selection are location accuracy, speed accuracy, device battery life and cost of device. The transportation company will select a device from three supplier options A, B and C.

The following matrix provides the estimation of relative importance of the criteria.

	Location Accuracy	Speed Accuracy	Battery Life	Cost of Device
Location Accuracy	1.00	1.25	1.50	4.00
Speed Accuracy	0.80	1.00	1.25	3.00
Battery Life	0.67	0.80	1.00	2.00
Cost of Device	0.25	0.25	0.50	1.00

The following matrices provide the relative favorability of the devices with respect to the criteria.
