You recently noticed that there is a bottleneck in the production line where the finished products are not transported immediately to the packing station. After some discussion with the operations manager, installing a conveyor system from the end of the production line to the packing station seems like a possible solution. If MARR is 20% and the study period is 10 years, select the best conveyor system from the following table using the incremental IRR analysis. Calculate the internal rate of return of the final selected conveyor system. Conveyor systems Slider Bed or Belt over Roller Live Roller AC Chain Driven Live Roller (CDLR) AC Gravity Flexible Initial cost (RM) 600000 650000 680000 500000 Productivity (RM/year) 155000 174000 164000 118000 Maintenance cost (RM) 1300 every year 1500 every year 1200 every year + 3000 every 5 years 1000 every year Salvage value (RM) 80000 50000 120000 none
