A recent surge in demand has convinced the production team that they need to boost their production capacity. The top management set aside $5,000 that they can invest in upscaling the throughput of the process. They would like to make the biggest throughput improvement possible with that money. The tables last column shows how much it costs to cut 5 seconds in the cycle time for each workstation. You can only reduce cycle times by multiples of 5 seconds. For instance, for workstation #2, you can invest $500 to cut 5 seconds, $1,000 to cut 10 seconds and so on However, you could not recommend cutting only 2 seconds at a prorated cost of $200. You must spend the whole $500.
