Dynamic Programming: use the tabular method

estion 4: [4 points] machine in a temporary factory is inspected every year. At the time of inspection you decide to either sell (or replace with a new one) or continue to run the same machine. In any given year, t the beginning of year1 and at the end of year 5 the factory is closed and the machine has to be sold. a) Draw the network diagram for machine replacement b) Given cost of maintenance is $100/year for every year that the machine is working. salvage is $50, cost of new machine is $250) revenue generated is $300 per year of working and discounting factor for value of money is 0.9 per year. Solve the network to find the optimal replacement policy that maximizes the revenue. estion 4: [4 points] machine in a temporary factory is inspected every year.
