Final Blueprint Flashcards
Materials and supplies that a firm carries either to sell or to provide inputs or supplies to the production process
Inventory
Quantities of goods in stock is known as
Inventory
What are 6 characteristics of service operations
Customer Participation
Simultaneity
Perishability
Intangibility
Heterogeneity
Nontransferable
What are the two forms of inventory
Accounting and Operational Inventories
Purchased items received, but not yet transformed
Raw Materials
Raw materials that have entered the transformation process and are in process or waiting
Work-in-progress
Products of the transformation process that are ready to be sold
Finished Goods
Why is inventory management important throughout the entire supply chain?
Inventory management generates valuable data that can be used for forecasting, demand planning, and supply chain optimization.
The planning and controlling of inventories to meet the competitive priorities of the organization.
Inventory Management
What are some of the pressures for small inventories
Inventory holding cost
Cost of capital
Storage and handling costs
Taxes
Insurance
Shrinkage
Pilferage
Obsolescence
Deterioration
What are some reasons for carrying inventory
1) Protect against lead time demand
2) Maintain independence of operations
3) Balance supply and demand
4) Buffer uncertainty (Safety Stock)
5) Economic purchase orders i.e buying in bulk to take advantage of reduced cost/unit
What are the 5 different types of inventory we have discussed
Cycle Stock
Safety Stock
Anticipation inventory
Pipeline inventory
Maintenance, Repair and Operating Items (MRO)
Inventory ready for immediate use, typically, produced in batches is known as
Cycle Stock
Extra inventory carried for uncertainties in supply and demand. This is also known as buffer stock
Safety Stock
Inventory carried in anticipation of events. This helps to smooth out the flow of products in supply chain
Also can be known as seasonal or hedge inventory
Anticipation Inventory
Inventory in transit
Exists because points of supply and demand are not the same is also known as transportation inventory
Pipeline Inventory
Inventory not directly related to product creation is known as
Maintenance, Repair and Operating Items (MRO)
What are the 3 inventory costs
Holding
Ordering
Shortage
Costs that vary with the amount of inventory held typically described as a % of inventory value
Also called carrying cost
Holding Cost
Cost involved in placing an order also referred to as “setup cost”
Ordering Cost
This cost occurs when we run out of stock
Shortage Cost
How do we determine how much to order using the Fixed-Order Quantity system?
Determined using the EOQ Formula
When do we determine to order using the Fixed-Order Quantity system?
When the Inventory Position (IP) reduces to the Reorder Point (ROP), an order is placed for the amount determined by the EOQ formula
How do we determine how much to order using the Fixed-time period system?
The order quantity is determined by subtracting the current inventory position (IP) from the Target Level (R)
Q=IP-R
How do we determine when to order when using a fixed time period system?
Orders are placed at fixed time intervals (T) when the Inventory Position (IP) is checked. “T” is pre-determined, i.e. every 2 weeks, every 30 days
An order of fixed quantity, Q, is placed when inventory drops to a reorder point, ROP. What system do we use to calculate the ROP?
Fixed-Order Quantity System “Q” System
Inventory is checked in fixed time periods, T, and the quantity ordered varies.What system is used to calcuate this answer?
Fixed-Time Period System “P” System
An order is only placed when inventory drops to a specified level, known as?
Reorder Point (ROP)
T/F-The amount requested in each order placed will always be the same quantity when used the fixed-order quantity system
True
T/F- the amount requested in each order placed will vary and is based refilling back up to the target inventory level “R” when using the fixed time period system
True
Demand for a finished product is known as
Independent Demand
Demand for components parts or subassemblies is known as
Dependent Demand
Relationships between independent and dependent demand is shown in a
Bill of Materials (BOM)
T/F- Dependent demand order quantities can be computed via an Materials Requirements Planning system (MRP)
True
An inventory control system used to compute order quantities for dependent demand inventory items is known as
Materials Requirements Planning
A list that shows all of the raw materials and subassemblies that go into a product. It also shows the quantities and relationships of items needed to make a final product
Bill of Materials (BOM)
Inventory management tool that classifies inventory based on its degree of importance. It gives priority to important inventory items
ABC Classification
T/F- Based on Pareto’s Law (80/20) – 20% of the inventory items (part numbers) account for 80% of the total inventory value
True
