If the sum of all task times is 100 seconds and the required cycle time is 21 seconds, what is the theoretical minimum number of workstations?
5 Reason: Nt= Sum of task times / Required cycle time = 100 / 21 = 4.76 - round up to 5.
For an assembly-line system with 6 workstations, the cycle time is 27 seconds and the sum of task times is 120 seconds. What is the efficiency of this balance?
74.1% Reason: Efficiency = Sum of task / (Actual number of workstations × Cycle time) = 120/ (6 × 27) = 120/ 162 = 0.741 = 74.1%

Which common layout format refers to the progressive build of a product?
Assembly line Reason: An assembly line refers to the progressive build of a product linked by some sort of material handling device.
The efficiency of an assembly-line balance must always be less than or equal to %.

Which process layout is best used for manufacturing liquids?
Continuous Reason: Continuous process is used for manufacturing items such as liquids, chemicals, and drugs.
Days of Supply formula
Days-of-Supply = Average inventory / Cost of goods sold × 365
Which of the following is not a step required to make a good?
Decoupling
Which of the following is NOT a step in the process of developing a manufacturing cell?
Determine which machines perform the same process.
True or false: The total work at a workstation is equal to the sum of all tasks to complete a product.
False
Identify the true statements about assembly-line and continuous process layouts.
In a continuous process, a product moves continuously through the process. In an assembly line, a product goes through a progressive set of steps. Often, the item being produced in a continuous process is a liquid or chemical that actually flows through the system.
Little's law relates inventory, throughput rate, and flow time as
Inventory = Throughput rate x Flow time
Which of the following statements about inventory measures is TRUE?
Inventory turn compares cost of goods sold to average inventory. Days-of-supply measures how long (on average) a firm's inventory can support sales.

The point in the supply chain where inventory is positioned to allow the preceding processes to operate independently is the
customer order decoupling point.
The required workstation cycle time is determined by
dividing the production time per day by the required output per day.
