method analysis employs which of the following charts in its analysis of the movement of workers and materials
flowchart
a product whos eoq is 40 experiences a decrease in ordering cost from 90 per order to 10. the revised EOQ is
One-third as large
a time study is being conducted to determine the standard time for a job that is made up of several elements. this standard time requires as inputs
the average observed time for each element
which of the following statements describes job rotation
the operator is allowed to move, for example from one type of CNC machine to the other
insurance and taxes on inventory are part of the costs known as setup or ordering costs
false (holding or carrying costs)
the reorder points is the inventory level at which action is taken to replenish the stocked item
true
if setup costs are reduced by substantial reductions in setup time the production order quantity is also reduced
true
if the actual order quantity is the economic order quantity in a problem that meets the assumptions of the economic order quantity model shown below, the average amount of inventory on hand
is one half of the economic order quantity
work in process inventory is devoted to maintenance, repair, and operations
false
timing a sample of a worker's performance and using it to set a standard is the work measurement technique of
time studies
the two most basic policies associated with employment stability are
follow demand exactly and hold employment constant
ergonomics is not concerned with
adequate compensation schemes
the goal of a human resource strategy is to manage labor and design jobs so people are effectively and efficiently utilized
true
psychological factors have little relevance in the design of assembly line jobs since they involve physical products and production technology
false
an inventory decision rule states "when the inventory level goes down to 14 gearboxes, 100 gearboxes will be ordered" which of the following statements is true
14 is the reorder point and 100 is the order quantity
in the quantity discount model, the cost of acquiring goods (product cost) is not a factor in determining lot size
false
in the basic EOQ model , if D= 5000 per year, S=$100, H=$5 per unit per month, the economic order quantity is approximately
129
flextime is a system that allows employees, within limits, to determine their own work schedules
true
the visual workplace
all of the above
the physical environment in which employees work may affect the quality of work life but it does not affect their performance and safety
false
ABC analysis divides on hand inventory into three classes, generally based upon
annual dollar volume
a major change in inventory management is to maintain a balance between inventory investment and customer service
true
the assumptions of the production order quantity are met in a situation where annual demand is 3650 units, setup cost is $50, holding cost is $12 per unit per year, the daily demand rate is 10 and the daily production rate is 100. the production order quantity for this problem is approximately
184
a manufacturing plant allows its engineers to come in at 7 AM. plus or minus an hour but still requires them to work 8 hour days. Which of the following scheduling techniques is the firm employing?
flextime
in the simple EOQ model, if annual demand were to increase the EOQ would increase proportionately
false
in the production order quantity model, inventory does not arrive in a single moment but flows in a steady rate, resulting in a larger lot size than in an otherwise identical EOQ problem
true
a product demand of 2250 units per year. ordering cost is 20 dollars and holding cost is $4 per unit per year. the cost-minimizing solution for this product is to order
150 units per order
the two extremes of employment stability policy are "follow demand exactly" and "keep demand constant"
false ("keep employment constant")
managers should seek to control such work environment factors as
all of the above

temperature, air quality, noise and vibration, illumination
the primary purpose of the basic economic order quantity model shown below is
to minimize the sum of setup cost and holding cost
the two most basic inventory questions answered by the typical inventory model are
timing and quantity of orders
an operations chart, or right hand/left hand chart, points out wasted motion and idle time
true
the hawthorne studies, which showed that there is a dynamic social system in the workplace, took place in the 1960s
false 1920s
two uses of labor standards are to determine the labor content of items produced and to determine staffing needs
true
companies like ABB and GE are heavily reliant on forecasting and inventory metrics, such as inventory turns, to make important managerial decisions in their operations
true
one advantage of cycle counting is that it maintains accurate inventory needs
true
a time study procedure involves timing a sample of worker's performance and using it to set a standard
true
according to mark hemman good sound operational data and metrics are all you need to have a successful project in industry
false
labor standards are defined as the
amount of time required to perform a job or part of a job
most inventory models attempt to minimize
total inventory based costs
technology, location, and layout decisions are all possible constraints on the human resource strategy
true
mark hemman from GE presented on DMEDI which is essentially the same process as DMAIC
true
a worker completed a job 10 times during a period in which a normal, trained employee completed the task 8 times. what is the workers performance rating
125% (10/8)
ergonomics is a branch of economics that deals with the costs of scheduling workers
false
in a large aerospace company, it has been discovered that some insulators have been damaged.A methods specialist is sent out to follow the insulators through the production and storage process and to try to find out where in the process they are damaged. the specialist should use
flowcharts
suppose that the allowance factor for a job is .5 and the normal time is 5 hours. what is the standard time?
10 hours
standard time=normal/1-allowance time
ABC analysis is based on the presumption that carefully controlling all items is necessary to produce important inventory savings
false
