A benefit of small lot sizes in lean systems is that each product is produced less frequently. True False?

11. If a firm’s product mix is 60% of product A and 20% each of products B and C, an optimal mix-model production schedule would be successive sequences of AAABC.
True False
FALSE
An optimal schedule would be successive sequences of ABACA.
12. Quality and highly capable production systems are requirements for the successful implementation of lean operations.
True False
TRUE
These help prevent waste.
13. The small lot-sizing policy works well in a situation where both holding costs and setup costs are high.
True False
FALSE
Small lot-sizing is only workable when setup costs are low.
14. The use of small lot sizes in lean operations is in conflict with the EOQ approach since setup costs tend to be significantly higher than holding costs.
True False
FALSE
These are not in conflict, since with low setup costs the EOQ leads to small lot sizes.
15. A basic requirement for operating with low inventories in lean systems is that major system problems must already have been solved and new problems will be solved as they appear.
True False
TRUE
Unless these problems are solved, steps required to work with low inventories are economically infeasible.
16. A benefit of small lot sizes in lean systems is that each product is produced less frequently.
True False
FALSE
Product versions are produced more frequently in lean systems.
17. In the lean philosophy, the larger the lot size, the easier it is to schedule.
True False
FALSE
In the lean system, items with large lot sizes tend to be scheduled less frequently.
18. Setup time and its associated cost can often be reduced by the use of group technology.
True False
TRUE
