Sequencing Orders • What order do I go in??? • Due Date • Similarity Set-ups • Demand Associated to it • Algorithm • Optimization
End Panel Example Bases - 106” or Vanities - 97” Length 61” Both Products Upper Strip s Base End Panel
End Panel Algorithm • Constraints • 1 strip per 6 base cabinets • 97” strip could make: • 3- 30” upper end panels • 2 – 42” upper end panels and 1- 12” • 106” strips could make: • 3- 30” upper end panels and 1 -12” • 2 – 42” upper end panels and 1 – 18” • 2 – 42” upper end panels and 1 – 12”
End Panel Ex. Continued • Constraints: • Volume and Usage varied by color • Maples and Cherries tend to have more 42” cabinets • Oak tended to have more 30” cabinets • Some colors were less popular and could be ran less often (12 day inventory versus a 3-day inventory) • Set-up was not short • Operators & Supervisors used to doing whatever made numbers look better • Supervisors did not like to follow a scheduling system or turn in inventory numbers. • Shipping Schedule varied by day (20 trucks scheduled on Saturday versus 8 on Friday) • Staffing different by day.
End Panel Algorithm • Used a Min/Max system with orders • Used MRP system (AS400) to generate quantities based on # of days looked in the future for orders • Downloaded Information into Excel • Used an Algorithm to maximize the set-up without overproducing one size of upper end panels. • Excel printed out report • Supervisors reported what they actually did to feed it back into the system.
