b. products become more customized
c. production systems become less automated
d. production systems become more flexible
Problem 6. Simulation is very limited in the number of operational problems to which it can be applied.
Problem 7. Another name for on-demand delivery is direct response.
Problem 8. Package delivery is for very large deliveries and is fast and reliable.
Problem 9. A Value added tax is defined as the total cost of producing a product and the value it adds to the supply chain partners.
Problem 10. Subcontracting is a feasible alternative for meeting demand if a supplier can reliably meet quality and time requirements.
Problem 11. Most companies use mixed strategies for production planning.
Problem 12. The process of breaking an aggregate plan into more detailed plans is referred to as
a. collaborative planning
b. hierarchical planning
c. disaggregation
d. rough-cut planning
Problem 13. The difference between planned production and customer orders is known as the

c. capable-to-promise
d. disaggregate plan
Problem 14. Yield management can be used to address all of the following problems except
a. overbooking
b. portioning demand into fare classes
c. single order quantities
d. master production scheduling
Problem 15. To determine the demand for dependent items a forecast of their requirements is needed.
Problem 16. Products with simple structures typically do not need material requirements planning (MRP) to plan production or monitor inventory levels.
Problem 17. Information concerning on-hand quantities, on-order quantities, lot sizes, safety stock, lead time, and past usage figures can be found in the master production schedule (MPS).
Problem 18. Enterprise Resource Planning (ERP) is software that organizes and managers a company's business processes by sharing information across functional areas.
Problem 19. A manufacturing environment in which previously subassembled components are configured to order is called Assemble to order.
Problem 20. Enterprise Resource Planning (ERP) is software that helps integrate many of the supply chain components by sharing and organizing information and data among supply chain members.
Problem 21. RFID is capable of keeping track of items on planes and ships as the items move throughout the global supply chain.
Problem 22. Seasonal patterns are associated with the seasons of the year and cannot occur on a daily or weekly basis.
Problem 23. A forecast is never completely accurate.
Problem 24. A gradual, long-term up or down movement of demand is called a trend.
Problem 25. Costs resulting from lost sales because demand cannot be met are easier to determine than carrying costs or ordering costs.
Problem 26. The ABC classification system is a method for classifying inventory in which a small percentage of (A) items account for most of the inventory value.
Problem 27. Six Sigma quality is a statistical measure that equates to only 3.4 defects per million customer 'opportunities'.
Problem 28. The degree to which quality characteristics are designed into the product is known as reliability.
Problem 29. Subjective perceptions are not an important dimension of quality for manufactured products.
Problem 30. The dimension of quality related to the life-span of a product before replacement is known as durability.
Problem 31. Quality characteristics included in the product's design must be balanced against production costs.
Problem 32. Frequently, the number of arrivals per unit time to a service facility is described by a Poisson distribution.
Problem 33. Balking occurs in a waiting line when customers move from one line to another that they believe is moving faster.
Problem 34. The probability distribution that is most commonly used to describe service times is the negative exponential distribution.
