    Ch 8 material handling Ch 8 material handling Presentation Transcript

      • Important concepts in Material Handling
      • Material Handling
      • Unitization
      • Palletisation
      • Containerization
      • Inter-modal transportation and related benefits
      • Lead-time
      • Cost
      • Material handling
      • Definition: “the art & science of moving, packing & storing substances in any form”
      • Receiving, moving, storing, dispatching activities
      • Impact on Quality, cost [capital as well as running], Delivery & Safety
      • Objectives of material handling
      • Movement minimization
      • Cost minimization
      • Time minimization
      • Commonly used equipment - forklifts, EOT Cranes, hoists, pulley blocks, trolleys, railroad cars, conveyers, ropes, slings, carousels, sortations, robotics
    • Unitization, unit loads
      • Benefits of Unitization & unit loads
      • Ease of movement
      • Standardization of handling equipment,
      • methods and training
      • Reduction in time and cost of handling
      • Inbound shipment checking is simplified
      • product protection is improved
      • Examples: bottles in crates, steel sheets in coils, steel ropes in coils etc. container is an example of unit load.
    • Palletization Pallet is a Unit load platform
      • Benefits of Palletization
      • Unit load is secured on a pallet, pallet provides a secure base for the unit load
      • Leads to containerization, container is a (unit load) self contained, ie., unitized and palletized, shipping unit
      • Facilitates use of standardized handling equipment like a forklift or a crane
      • Palletized unit loads bring down time of handling and cost of handling
      • Ensures safe handling
      • Product is well protected
      • Types of pallets
      • Wooden pallets
      • Plastic pallets
      • Composite pallets
      • Refrigerated pallets: self-contained shipping units for refrigerated materials
      • Pallet pools
      • central pools to collect pallets and issue pallets to global business
    • pulley block forklift
    • conveyers
    • Automatic Guided Vehicles
      • Principles of material handling
      • Planning - high impact on cost
      • Integration – material handling decision should be part the corporate strategy-foundation, floors, layout, product
      • Standardization – handling methods, equipment, software
      • Work – minimum handling
      • Ergonomics – tasks, equipment and human beings
      • Use of gravity- always use gravity to advantage
      • Unit load- handle only in unit loads
      • Space utilization- use space and not area, EOT rather than F/Ls
      • System – integrate handling & storage (O/H tanks and pipe lines) and form Operational Material Handling System
      • Auomation - need based
      • Environment - explosive?
      • Signs of Poor Material Handling
      • Cluttered floor
      • Accidents
      • Excess inventory
      • High waiting time, high Through Put Time, poor flow of material
      • Excessive handling
      • Poor quality of product, high scrap
      • Lack of standardization
      • Poor use of skilled labor
      • Material handling system
      • Types of Material Handling Systems: Manual, mechanized, automatic, computerized
      • Elements of the system: human, equipment, storage, packaging
      • Equipment selection & Purchase
      • Full utilization of existing equipment
      • Overall cost reduction
      • Standardization
      • Integration with current system
      • Alternate methods – production should not halt
      • Facility limitation, building, floors etc
      • Future plan
      • Maintenance support
      • Life cycle cost
