Bridgeport Electronics is a small facility that distributes integral circuits throughout the Northeastern United States. It has seen an increase in orders recently due to the collapse of its biggest competitor. The management team is trying to decide on a more efficient workflow order to keep up with the demand. The customers have not designated due-dates, and fortunately, Bridgeport Electronics does not have to pay any inventory holding costs. The only issue at this point is that there has been a delay in producing circuit boards because a buffer behind one of its smaller machines hsa been filing up. What scheduling system should Bridgeport Electronics utilize to improve this process?
