Case Study:Balloons Aloha
Susie Davis owns Balloons Aloha and must fill balloons with helium and assemble them into certain configurations today for six major parties. Her six customer jobs all need to use the same helium tank, (that is, the single processor), and she was wondering what might be the best way to sequence these jobs. Client (job) number 5 is Balloons Aloha's top customer. Her assistant store manager, Lee Sailboat, wants to process them in sequential order, (1, 2, 3, 4, 5, and 6). Since the balloons lose air quickly, the company waits until the day of the parties to fill them and then the workload is hectic. Business is booming and growing about 15 percent per year in their new store location. The job processing times are as follows:
Job 1 2 3 4 5 6
Processing time (min.) 240 130 210 90 170 165
Due dates (6 am-midnights in min.) 240 360 480 240 720 780
