  2. Agenda • Capacity Model (3.0) • Changes since 2.8 • Validation Process • Overall Capacity • What’s Next

  3. Capacity Tool Global Changes • Removal of Global units per line • Added “Delay Allowance” • Calculated Effective Shift Length • Added color coding to Max Workers

  4. Capacity Tool Changes Pick Areas • Removed unnecessary ADM input fields • Identified and fixed error in ADM labor hour calculations • New Pick Times (excludes breaks and lunch)

  5. Validation • Compared our calculated numbers against a one month sample of actuals • Used Total Labor Hours as metric • Calculated based on daily demand • Results: Calculated labor hours were 5.5% less than actuals (avg. of all areas)

  6. Overall Capacity • Provided four options of presentation • MTBF/MTTR • Upper & Lower Bounds • Independent Areas • Bottleneck Identification • Selection was a combination of Independent areas and Bottleneck ID

  7. Overall Capacity • ADM @ 95% uptime: 534 orders/hr • PTL: 260 lines/hour/person • Voice: 101 lines/hour/person • Carousel: 206 lines/hour/person • Bottleneck is a factor of pick times, people and demand in area

  8. Next Steps • Finalize Documentation for Capacity Tool • Focus on Overall Capacity Analysis • Addition of Pack to Capacity Tool • (If time allows)
