The cutter bars of two combine harvesters from different manufactures develop different failure types with time. Cutter bar A loses the knife sharpening after 10 seasons, while cutter bar B does not lose the knife sharpening but some blades have to be replaced time to time due to local fracture of the edge. Through measuring the volume and the weight the density of both blades are around 7.8 – 7.9 Kg/dm3. The hardness of the blades from A is 2.2...

A firm must purchase an electronic control device. Device A costs $10,000 and lasts for 3 years. Annual maintenance costs in each of the years are $1,800 $1,400 and $1,300 respectively. Device B costs $15,000 and lasts for 4 years. Annual maintenance costs in each of the years are $1,700, $1,100, $1,070, and $1,100 respectively. These two devices service the same purpose (i.e., are mutually exclusive) and the firm needs to use this device for its day-to-day operations. If the...
