A capacity cushion is the amount of capacity less than expected demand.
FALSE
A decision tree problem does not need probabilities or payoffs to generate a solution.
FALSE
A production facility develops virtuosity and works best when it focused on a widely varied set of production objectives.
FALSE
Best operating level is usually a multiple of the level of capacity for which a process was designed.
FALSE
Capacity planning is generally viewed in three time durations: Immediate, Intermediate and Indeterminate.
FALSE
In a decision tree, the only time probabilities are applied to a decision node is when the decision is being made by someone else such as you customer or your competitor.
FALSE
In decision tree analysis the time value of money is ignored because you are only concerned with cash costs.
FALSE
In practice, achieving a perfectly balanced plant is usually desirable but impossible.
FALSE
Low rates of capacity utilization in service organizations are never appropriate
FALSE
Making adjustments to eliminate the variance between planned and actual output is tied into intermediate range capacity planning.
FALSE
Overtime and personnel transfers are solutions to capacity problems in the intermediate term.
FALSE
The capacity cushion is the ratio of capacity used to the best capacity level.
FALSE
The capacity utilization rate is found by dividing best operating level by capacity used.
FALSE
The larger the capacity cushion the better.
FALSE
The objective of strategic capacity planning is to determine the overall capacity level of capital intensive resources (including facilities, equipment, and overall labor force size) that best supports the company's short-range competitive strategy.
FALSE
The objective of strategic capacity planning is to provide an approach for determining the overall capacity level of labor-intensive resources.
FALSE
The probability of each occurrence at a decision tree chance node is the reciprocal of the number of possibilities at the chance node.
FALSE
The problem of keeping demand sufficiently high to keep a large factory busy is a sales issue and not a diseconomy of scale.
FALSE
The smaller the capacity cushion the better.
FALSE
The ultimate in plant flexibility is a one-hour-changeover time plant.
FALSE
A piece of equipment with twice the capacity of another piece typically costs twice as much to purchase and to operate.
TRUE
A production facility works best when it focuses on a fairly limited set of production objectives.
TRUE
At some point, the size of a growing plant can become too large and diseconomies of scale become a capacity planning problem.
TRUE
Because services cannot be stored for later use, service managers consider time as one of their supplies or resources.
TRUE
Best operating level is the volume of output at which average unit cost is minimized.
TRUE
Capacity can be defined as the ability to hold, receive, store, or accommodate
TRUE
Capacity can be defined as the amount of available resource inputs relative to requirements for output over a particular period of time.
TRUE
Capacity flexibility means having the ability to rapidly increase or decrease production levels, or to shift production capacity quickly from one product or service to another.
TRUE
Economies of scope exist when multiple products can be produced at a lower cost in combination than they can separately.
TRUE
In practice achieving a perfectly balanced plant is usually both impossible and undesirable.
TRUE
In solving a decision tree problem, calculations start at the ends of the "branches" of the tree and work backwards to the base of the tree.
TRUE
Long-range capacity planning requires top management participation.
TRUE
Outsourcing is a common source of external capacity
TRUE
Sharing capacity is a common source of external capacity.
TRUE
The basic notion of economies of scale is that as a plant gets larger and volume increases, the average cost per unit of output drops.
TRUE
The frequency of adding to productive capacity should balance the costs of upgrading too frequently and the costs of upgrading too infrequently.
TRUE
The objective of strategic capacity planning is to determine the overall capacity level of capital intensive resources (including facilities, equipment, and overall labor force size) that best supports the company's long-range competitive strategy.
TRUE
When a firm's design capacity is less than the capacity required to meet its demand, it is said to have a negative capacity cushion.
TRUE
When evaluating capacity, managers need to consider both resource inputs and product outputs.
TRUE
