Question

2. A transportation service provider wants to select a telematics device to track the movement of its fleet of trucks. The device is attached to a truck and transmits location and speed of the truck for operational planning purposes. 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 options A, B and C The following matrix provides the estimation of relative importance of the criteria. Location Accuracy Location Accuracy Speed Accuracy Battery Life Cost of Device 0.25 0.50 0.33 Speed Accuracy 4.00 1.00 2.00 1.33 Battery Life 2.00 0.50 Cost of Device 3.00 0.75 0.67 1.00 The following matrices provide the relative favorability of the devices with respect to the Location Accuracy: Device A Device B Device C Device A Device B 1.50 Device C 0.67 1.25 1.00 0.80 Speed Accuracy: Device A Device C 2.00 Device A Device B 0.67 HW1 ISE 105 Spring 2019 Device B Device C 1.50 2.00 Battery Life: Device A Device B Device C Device C 0.50 0.33 Device A Device B 0.67 3.00 Cost of Device: Device A Device Device C Device A 1.00 0.55 0.50 Device B 1.80 1.00 0.80 Device C 2.00 1.25 1.00 Select the best device using the Analytic Hierarchy Process. 50 points

Answer 1

The best device is Device A as its final weighted score of 0.406 is highest among all the three devices.

The various matrices as per Analytic Hierarchy Process are given below:
