Problem 18-35 (Lean Tools and Approaches) A plastic Injection molding machine operates 348 days a year. It is the bottleneck workstation in a process than produces plastic housed wall clocks. Industrial engineers collected data on the probability of machine breakdowns, the costs of preventive maintenance, and the cost of a breakdown Number of Molding Machine Breakdowns 0 1 2 3 4 per Day Probability of a breakdown 0.32 0.28 0.22 0.13 0.05 The cost of preventive maintenance is high due to performing it between 1 and 4 am, each day by two machine experts. The preventive maintenance cost is $1,980 per day including replacement parts, deaning, and software upgrades. The cost of a breakdown of $1,850 is also high because the downstream workstations can only work until all work-in-progress inventory is completed; then the entire process must stop. What are the economics of the situation? Do mot round intermediate calculations. Round your answers to the nearest cent. The expected cost of a breakdown per day is $ The manufacturing firm saves per year by performing preventive maintenance daily on the injection molding machine
