QUESTIONS WITH SOLUTIONS GRADED A+
◍ Time Fences.
Answer: Act as boundaries between periods in the planning horizon;
corresponds to the cumulative lead time to make a product; events outside of
the time fence are not captured in the master schedule.
◍ Taguchi.
Answer: Used Robust DesignParabolic Quality Loss FunctionPerfecting of
experiments to create higher quality products and processesArgues that
quality must be designed into a product
◍ Design of Experiments (DOE).
Answer: Real-time solving of problems within complex systems with many
different factors that are difficult to isolate.
◍ Master Schedule.
Answer: Indicates which items and how many of each item to produce.
◍ Relative Advantage.
Answer: Where one entity has an advantage over another; will often trade
their specialized products for those that they do not produce; companies
with a relative advantage are able to produce products at a lower cost than
their competitors.
◍ Functional Areas.
Answer: Subsystems within an organization, such as marketing, finance, and
accounting, that are linked together by a common organizational goal.
◍ Assembly Line.
Answer: Process selection most appropriate to produce high volume with
little to no variation. Uses product facility layout (i.e. car manufacture)
,◍ Questions for Customers when Improving Products.
Answer: Ask what they value (not just what they want), how do they work,
what makes them happy, and feedback on specific product attributes.
◍ Efficiency.
Answer: Actual Output / Effective Capacity; used to measure how much
effective capacity is being used to achieve output.
◍ Master Production Schedule.
Answer: Based on the aggregate plan, this schedule provides more detail,
such as identifying the cubic feet, energy efficiency, and layout of a fridge
model; determines the exact product mix that a company will use;
disaggregates the aggregate plan; for example, whereas the iPod may be the
basis for the aggregate plan, the 5th Generation iPod Touch in Gray and
Silver is reflected in the master production schedule.
◍ Philip Crosby.
Answer: Wrote Quality is Free; he emphasized the complete elimination of
failures to save money, as most firms underestimate their failure costs and
should evaluate all costs of quality; "Do it right the first time".
◍ ERP (Enterprise Resource Planning).
Answer: More robust data driven system that stems from MRP II. Used
when all corporate data needs to be accessible to all employees.
◍ Time Series Data.
Answer: A series of values of a quantity obtained at successive times, often
with equal intervals between them.
◍ Variable costs.
Answer: Are those which change and can be adjusted as business conditions
change
◍ Serviceability.
Answer: Speed, courtesy, and competence of repair.
◍ Quality Planning.
, Answer: The development of products that appeal to the changing wants and
needs of customers.
◍ Six Sigma.
Answer: A continuous improvement strategy that relates to the firm's ability
to produce error free products. Specifically - 3.4 defects per 1 million units.
DMAIC o Define o Measure o Analyze o Improve o Control
◍ Scatter Plot (diagrams).
Answer: Displays data as a relationship to show the correlation between two
variables.
◍ Constraint.
Answer: When a resource's capacity to less than or equal to demand for that
resource.
◍ MPS Inputs.
Answer: o Demand Forecasto Inventory Levelo Customer Orderso
Production Capacityo Inventory/Production Costs
◍ Independent demand.
Answer: Items usually include finished products, such as the completed
tricycle or replacement parts sold to customers.
◍ Transportation (pipeline):.
Answer: The portion of inventory that is in the process of being shipped
through the distribution system.
◍ Facility location.
Answer: The placement of a facility with regard to a company's customers,
suppliers, and other facilities with which the company interacts based on
quantitative and qualitative factors. Quantitative factors are easily
measurable and are usually assigned a numerical value, while qualitative
factors are more subjective and are usually not enumerated.
◍ Long-range operations planning.
Answer: Planning for facility location, technologies, and capacity that
, typically extends 5 to 10 years
◍ Line Flow Processes.
Answer: Low variety operations; have high fixed costs and low variable
costs.
◍ ABC analysis.
Answer: Has been developed to determine which inventory items should
receive the highest level of control. By multiplying the dollar value of each
item by its annual usage, a dollar usage value can be obtained. Dollar usage
follows the Pareto Principle in that frequently, only 20% of all the items
account for 80% of the total dollar usage, while the remaining items
frequently account for only 20% of the dollar usage. This principle leads to
the _____ classification, which is based on focusing efforts where the payoff
is highest
◍ Product Bottleneck.
Answer: When there are insufficient materials to make a product.
◍ Constraint.
Answer: Any resource whose capacity is less than or equal to demand for
that resource
◍ System.
Answer: The process of producing goods and system.
◍ Mean Squared Error (MSE).
Answer: The average of all the squared errors; square each of the error rates
(the difference between the actual and the predicted results), add them
together, and divide by the number of periods.
◍ Level Assembly Schedule.
Answer: The number of units of each end product produced at a time is as
small as possible, and the total production of each matches average demand
during the scheduling horizon. For example, if the scheduling horizon is 20
days, and the demand during that period is expected to be 300 units, a level
schedule work require 15 units (300/20) be produced per day. Makes
