  2. Backward scheduling
    Scheduling backward from due date to determine when to begin job
  3. Best-of-breed
    The selection of ERP modules from different vendors
  4. Big data
    Very large volumes of both structured and unstructured data
  5. Bill of material (BOM)
    a list of all materials, parts, and assemblies that make up a product, including quantities, parent-component relationship, and order of assembly
  6. Capacity requirements planning (CRP)
    a computerized system that projects the load from a given material plan onto the capacity of a system and identifies underloads and overloads
  7. Cloud computing
    on-demand IT services usually delivered over the Internet; includes data storage as well as Saas
  8. Cumulative lead time
    The total length of time required to manufacture a product, also the longest path through a product structure
  9. Customer relationship management (CRM)
    software that plans and executes business processes that involve customer interaction, such as sales, marketing, fulfillment, and customer service
  10. Cycle counting
    A method for auditing inventory accuracy that counts inventory and reconciles errors on cyclical schedule rather than once a year
  11. Efficiency
    • how well a machine or worker performs compared to a standard output level
    • Effective daily capacity = (no. machines or workers) * (hours per shift) * (no. of shifts) * (utilization) * (efficiency)
  12. Enterprise resource planning (ERP)
    • software that organizes and manages a company's business processes by sharing information across functional areas
    • SAP, Oracle Corp, Oracle, Infor, QAD, Microsoft dynamics
  13. Expedite
    to speed up orders so that they are completed in less than their normal lead time
  14. Explosion
    The process of determining requirements for lower-level items by multiplying the planned orders of patron items by the quantity per assembly of component items
  15. Forward scheduling
    Scheduling forward from today's date to determine the earliest time a job can be completed
  16. Item master file
    • a file that containsĀ en extensive amount of info on every item that is produced, ordered, or inventoried in the system
    • -on hand quantities, on order quants, lot sizes, safety stock, lead time, past usage figures
  17. Load
    Standard hours of work assigned to a facility
  18. Load leveling
    • The process of balancing underloads and overloads
    • smooth out the resource requirements so that capacity constraints are not violated
    • -acquiring more work, pulling work ahead that is scheduled for later periods, reducing normal capacity
  19. Load percent
    • the ratio of load to capacity
    • Load / capacity * 100
  20. Load profile
    A chart that compares released orders and planned orders with work center capacity
  21. Lot sizing
    Determining the quantities in which items are usually made or purchased
  22. Master production schedule (MPS)
    • A schedule for the production of end items. Specifies which end items or finished products a firm is to produce, how many are needed and when they are needed. It drives the MRP process that schedules the production of component parts
    • -Quantities represent production, not demand
    • -Quantities may consist of a combination of customer orders and demand forecasts
    • -Quantities represent what needs to be produced, to what can be produced
    • -Quantities represent end items that may or may not be finished products
  23. Material requirements planning (MRP)
    • Computerized inventory control and production planning system for generating purchase orders and work orders of materials, components, and assemblies
    • Inputs; planned order releases, routing file, open order file
  24. Modular bill of material
    Special bill of material used to plan the production of products with many optional features
  25. Netting
    Process of subtracting on-hand quantities and scheduled receipts from gross requirements to product net requirements
  26. Periodic order quantity
    Lot sizing technique that orders at set time intervals
  27. Product lifecycle management (PLM)
    Software that manages the product development process, product lifecycles, and design collaboration with suppliers and customers
  28. Product structure file
    File that contains computerized bills of material for all products
  29. SaaS
    Software as a service, on-demand access of software from a provider's site
  30. SOA
    Service-oriented architecture; a software architecture that bundles together stand-alone services
  31. Supply chain management (SCM)
    software that plans and executes business processes related to supply chains
  32. Time fence
    A date specified by management beyond which no changes in the master schedule are allowed
  33. Time-phased bill of material
    Assembly chart shown against a time scale
  34. Time phasing
    process of subtracting an item's lead time from it's due date to determine when an order should be released
  35. Utilization
    The percentage of available working time that a worker spends working or machine operating
  36. XML
    extensible markup language; used to help different ERP systems communicate over the internet
  37. Entries in matrix
    • Gross requirements - derived from MPS or planned order releases of the parent
    • Scheduled receipts - on order and scheduled to be received
    • Projected on hand - anticipated quantity on hand at the end of the period
    • Net requirements - Gross requirements net of inventory and scheduled receipts
    • Planned order receipts - when orders need to be received
    • Planned order releases - when orders need to be places to be received on time
