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 the following describes the layout for items produced through a fixed sequence of workstations?

Assembly line

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 %.

The - matrix shows when different production process types are used in relation to product volume and standardization.

Blank 1: product Blank 2: process

To determine the required workstation cycle time, an analyst needs to know the per day and the required per day (in units).

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.

True or false: The longest required task time often defines the shortest possible workstation cycle time for production.

True

True or false: Typically, there is a trade-off where quicker response to customer demand comes at the expense of greater inventory investment.

Which of the following is not a way to reduce the required time for a task?

Use a less skilled worker Reason: A more skilled worker may reduce the required time for a task.

ascertain the quantity at which the initial investment starts to make a profit

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.

The time required to respond to a customer order is known as

lead time.
