Objectives of Warehouse Management 28 • Maximum use of space • capital cost of space is very high • Effective use of labor and equipment • material handling equipment is the second largest capital cost • need best mix of equipment and labor • all SKU’s should be easy to find • move goods efficiently
  29. 29. 29 Warehouse Effectiveness – Concepts Stock location Cube utilization and accessibility Order picking and assembly
  30. 30. 30 Warehouse Effectiveness - Space • Goods are stored on the floor and in the space above • Space also required for: • Aisles • Offices • Receiving • Order picking • Shipping docks • Order assembly • Need to know the maximum space required Stock location Cube utilization and accessibility Order picking and assembly
  31. 31. 31 Warehouse Effectiveness - Storage • Floor storage • Pallets are stacked on each other • Maximum stacking height • due to ceiling height/ weight restrictions • Need to allow for side clearance Stock location Cube utilization and accessibility Order picking and assembly
  32. 32. Warehouse Effectiveness–Pallet Space 32 Stock location Cube utilization and accessibility Order picking and assembly
  33. 33. 33 Activity 4 • A company wants to store an SKU consisting of 13,000 cartons on pallets each containing 30 cartons. How many pallet positions are needed if the pallets are stored three high?
  34. 34. 34 Warehouse Effectiveness - Location • Group functionally related items together • Group fast moving items together • Group physically similar items together • Separate working from reserve stock • Items that are similar in their use or characteristics • warehouse staff become familiar with items • similar order processing needs • often ordered together • hardware items • bulk items • security Stock location Cube utilization and accessibility Order picking and assembly
  35. 35. 35 Warehouse Effectiveness - Location • “A place for everything and everything in its place” • Fixed Locations reduce record keeping • Usually results in poor space utilization • space must be available for the replenishment order quantity • average of 50% utilization Stock location Cube utilization and accessibility Order picking and assembly
  36. 36. Warehouse Effectiveness– Accessibility 36 Stock location Cube utilization and accessibility Order picking and assembly • The ability to get goods with a minimum of effort • without moving other goods • can be a problem with multiple SKU’s in one area
  37. 37. 37 Warehouse Effectiveness– Utilization Stock location Cube utilization and accessibility Order picking and assembly • A measure of how well space is utilized • Should also consider accessibility • Racking allows accessibility to all goods while improving utilization
  38. 38. Warehouse Effectiveness– Utilization % 38 Stock location Cube utilization and accessibility Order picking and assembly (Space Used) x 100 Utilization % = (Total Space)
  39. 39. 39 Activity 5 • A warehouse has space for 14 pallets along its length and stacked 3 high. • The following items (SKU) are stored in the warehouse Item Pallet Pallet • What is the Utilisation? Position SKU A 4 2 SKU B 6 2 SKU C 14 5 SKU D 8 3 SKU E 5 2
  40. 40. Warehouse Effectiveness–Order Picking 40 • Once an order is received it must be: • retrieved • assembled • prepared for shipment • Involves labor and movement of goods to provide desired level of customer service • Order Picking Systems • Area System • Zone System • Multi-Order System • Working & Reserve Stock Stock location Cube utilization and accessibility Order picking and assembly
  41. 41. 41 Warehouse management for profit • The purpose of companies is to gain competitive advantage. • One way to achieve this is by lowering logistics costs. • The reduction of logistics costs diminishes the total cost of goods sold and therefore it helps companies have a higher profit margin or a cost advantage in comparison with their competitors.
  42. 42. 42 Inventory Performance KPIs MEASURE CALCULATION Damaged Inventory (min.) Total Damage (GH₡) / Inventory Value Days on Hand (min.) Avg. Month Inventory (GH₡) / Avg. Daily Sales/Month Storage Utilisation (max.) Avg. Occupied Sq. m. / Total Storage Capacity Dock to Stock Time (min.) Total Dock to Stock Hrs. / Total Receipts
  43. 43. 43 Warehouse Performance Indicators MEASURE CALCULATION Orders per Hour (max.) Orders Picked or Packed / Total Warehouse Labor Hrs. Items per Hour (max.) Items Picked/Packed / Total Warehouse Labor Hrs. Cost per Order (min.) Total Warehouse Cost / Total Orders Shipped Cost as % of Sales (min.) Total Warehouse Cost / Overall Sales
