How to invest LCD TV Final Assembly factory

Volume Requirements

• Total estimated time to complete weekly- production volumes with proposed equipment set = 160 hours/per week (+/- 10%)

Notes:

• Available time is 80 hours (16hours x 5days)!
• Factory efficiency not optimum due to:

• Weekly Scheduling
• Bottle Neck is SM Lines (Top/Bottom)
• Occupation of Lines, High Volume PC’s

• For schedule improvements we propose:

• To add and reconfigure SMT lines, create dedicated HV PC & PC Monitor SM lines
• Increase inventory, make longer runs, increase weekly batches, warming up Factory
