Working Capital Management Part 1 _ M4 Flashcards
What is Just-In-Time Inventory (JIT)?
- Involves maintaining a lower level of inventory.
- Requesting inventory from suppliers as needed.
- It is designed to reduce the carrying costs, while reducing the risk of inventory obsolescence.
- Involves fewer suppliers, as the relationships and coordination with suppliers is extremely critical.
- Having production employees make purchasing decisions is faster and more efficient.
- It is a pull-through inventory system, as the customer’s order drives the need for inventory.
What are some problems of using JIT Inventory?
- If the actual lead time takes longer than anticipated.
- Since you’re not buying in bulk, you lose the quantity discounts.
- Quick deliveries on short notice, could negatively affects the quality of inventory and cause inventory shortages.
What are the benefits of JIT?
- Supplies arriving at regular intervals throughout the production day.
- Reduced set-up time (lag-time) between inventory arrival and use.
- Employees with multiple skill sets being used for greater efficiency.
- Reducing the carrying costs of maintaining inventory.
JIT says inventory does not add value so why have it on hand?
What is the fundalmental concept of JIT?
The fundamental concept of just-in-time (JIT) inventory management is that inventory does not add value.
What is a traditional inventory system?
- Traditional approaches tend to maintain higher inventory levels.
- Requires less coordination with suppliers.
- Incurs greater carrying costs.
- Push systems begin with forecasting customer demand.
What does the level of safety stock depend on?
- Uncertain sales forecasts - greater uncertainty means a higher level of safety stock should be carried.
- Dissatisfaction of customers - if customers are dissatisfied with back orders, then more safety stock should be carried.
- Uncertain lead times - greater uncertainty means a higher level of safety stock is needed.
How to calculate safety stock?
Carry cost + Stock-out Cost = Safety Stock
Stockout Cost
Stockout units 100
Stockout cost per units × $5 = $500
Probability at 100 safety stock level × .15 = $75
Orders per year × 10
Expected stockout cost $750
Carrying Cost
Inventory investment per unit $50
Carrying cost percentage × 20%
Carrying cost per unit $10
Safety stock units × 100
Carrying cost $1,000
Total annual cost of safety stock of 100 units $1,750
What is the equation for reorder point for inventory?
or Safety Stock
Reorder Point = Safety Stock + (Lead Time × Sales).
What is the optimal level of inventory affected by?
- The time required to receive it.
- The cost per unit of inventory.
- The cost of placing an order impacts order frequency.
What is the fasted way to get capital for the firm?
- Accounts payable.
Additional ways to get capital:
- Accounts Receivables takes time to factor.
- Debentures takes time to issue.
- Preferred stock takes time to issue.
What are the elements in the Economic Order Quantity (EOQ) formula?
E= 2SO/C
- Take the square root of two times the annual Sales (in units) times the cost per purchase Order divided by the Carrying cost per unit (an amount that frequently includes insurance costs).
- (EOQ) method of inventory control anticipates orders at the point where carrying costs are nearest to restocking costs.
- The objective of EOQ is to minimize total inventory costs.
What are the assumptions associated with EOQ?
- The economic order quantity formula (EOQ) assumes that periodic demand is known. Annual sales volume is a crucial variable in the EOQ formula.
- The cost of placing an order is anticipated to remain constant.
What are carrying cost?
Carry cost per unit is expected to remain constant
- Opportunity cost of foregoing a return on the money invested in inventory.
All costs associated with warehousing (storing) inventory:
- Storage.
- Insurance.
- Obsolescence.
- Spoilage associated with holding inventory).
- Cost of capital invested in inventory.
What is Supply Chain Management?
- Is the close linkage and coordination of the activities involved in buying, making, and moving a product.
- Is involved with what, when, where, and how much of product manufacturing and sale.
- Supply chains have to be constantly reengineered as products change and to increase efficiency and reduce costs.
What are the 3 elements of Supply Chain Management?
- The Goal is to understand the needs and preferences of customers.
- Supply Chain Operations Reference (SCOR) Model (plan, source, make, deliver).
- Benefits of Supply Chain Mgmt.
