What is Source, Make, and Deliver?

The 3 steps in manufacturing.

What is Customer Order Decoupling Point?

Where the inventory is positioned in the supply chain. (Represented as an inverted triangle on diagram)

What is True? What is False?

Make-to-Stock makes finished goods without having specific customer orders.  (T/F)

Make-to-Order do not have raw materials on hand to produce when a customer order is received. (T/F)

Assemble-to-Order assemble components once a customer order is received.

Engineer-to-Order do not order parts until they have a design form their customer.

Explain the difference between Assemble-to-Order and Engineer-to-Order.

(Low) Engineer-to-Order / Make-to-Order / Assemble-to-Order / Make-to-Stock (High)

Arrange examples below from Low to High in terms of inventory investment.

Engineer to Order, Assemble to Order, Make to Stock, Make to Order.

What is a process map?

A visual that is used to demonstrate how a process is organized and where inventory is located within the process.

What is company A?

Take an example of 2 companies in the same industry.   Company A has 26 days of supply and Company B has 52 days of supply.  Which company is managing their inventory better based on this metric?

True

T/F. A process map can show long the transit time is.

What is Inventory?

A process map can show how many days of __________ are held at each location.

What is company A?

Take an example of 2 companies in the same industry.  Company A has annual inventory turns of 52 and Company B has annual inventory turns of 4.  Which company is managing their inventory better based on this metric?

What is Little's Law?

A powerful, but simple formula which describes the flow of items through a production process.

Long term average rate of flow through the process.

Define Throughput.

Time for a single unit to traverse the entire process.

Define Flow Time.

On average how many flow units are within the process boundaries at any point and time.

Define Inventory in the context of Little's Law.

Inventory = Throughput Rate x Flow Time

What is the formula for Little's Law?

What is true?

A project layout typically works with a customized product and specialized workers (T/F)?

False

Assembly line processes typically have less volume than workcenters?

What is a manufacturing cell?

One way to move from a workcenter process layout to an assembly line process layout is to use this type of process layout.

What is similar types of equipment?

Workcenter layouts are typically focused around _________.

What are products?

Assembly line process layouts are typically focused around similar ____________ . 

What is Assembly-Line Balancing?

Assigning tasks to a series of workstations so that the required cycle time is met and idle time is minimized.

What is Workstation Cycle Time?

What formula is this?

C = Production time per day / Required output per day

N_{t =} Sum of task times (T) / Cycle Time (C)

How do you determine the theoretical minimum number of workstations (N_t)?

Yes

If efficiency is unsatisfactory, can you rebalance using a different rule?

What is Efficiency?

What formula is this?

E = Sum of task times (T) / Actual number of workstations (N_a) x Workstation cycle time (C)
