Identify the bottleneck by computing total workload at

each workstation. The firm wants to satisfy as much of

the product demand in a week as it can. Each week

consists of $2400$ minutes of available production time.

Multiplying the processing time at each station for a

given product with the number of units demanded per

week yields the capacity load. These loads are summed

across all products going through that workstation and

then compared with the existing capacity of $2400$

minutes.
