A fully automated conveyor system is installed at Corporation Maternity that will have an initial investment of $1,000,000, and will require an upgrade of 25% of initial investment in software at the end of the 5 year. The company expects that the system will generate equivalent annual savings $300,000 and annual O&M costs of $75000 increasing by a gradient series of $5,000. The company expects that the robot will have a useful life of 10 years, and that time will have a salvage value of $100,000. The administration is concerned about the accuracy of the projected savings and increase per year (gradient) of the O&M costs. Perform a two parameter BTCF sensitivity analysis to determine the range in which these two parameters could vary to have a PW>0.
