Which process layout is best used for manufacturing liquids?

Continuous

_____________ is used to avoid expensive shut downs by operating 24 hours a day. Multiple choice question. Assembly line Workcenter Project layout

Continuous process

Inventory turn

Cost of goods sold/Average inventory

Last year a firm had an average inventory of $1,500,000 and the cost of goods sold was $3,750,000. What was the days-of-supply last year?

Days-of-Supply = Averageinventory/ Costofgoodssold ×365=$1,500,000/$3,750,000×365= 146

Which of the following is NOT a step in the process of developing a manufacturing cell? Multiple choice question. Determine which machines perform the same process. Physically regroup machines into cells. Group parts into families that follow a common sequence of steps. Identify dominant flow patterns for each f

Determine which machines perform the same process.

Little's law relates inventory, throughput rate, and flow time as

INVENTORY: throughout rate x flow time

Identify the true statements about assembly-line and continuous process layouts. Multiple select question. In a continuous process, a product moves continuously through the process. In an assembly line, the stations are completely independent of each other. Often, the item being produced in a continuous process is a liquid or chemical that actually flows through the system. In an assembly line, a product goes through a progressive set of steps

In a continuous process, a product moves continuously through the process. Often, the item being produced in a continuous process is a liquid or chemical that actually flows through the system. In an assembly line, a product goes through a progressive set of steps.

Last year a firm had an average inventory of $1,500,000 and the cost of goods sold was $3,750,000. What was the inventory turn last year?

Inventory turn = CostofgoodssoldAverageinventory=$3,750,000/$1,500,000=2.5

The long-term relationship between inventory, throughput, and flow time is mathematically related using

Little's law

Make-to-stock

Which layout format groups machines to work on products that have similar processing requirements?

Manufacturing cell

Which are characteristics of a continuous process line? Multiple select question. May operate 24 hours a day. Product is moved from one workstation to the next workstation in a sequence of events. Highly automated machinery is used. Shutdowns can be expensive.

May operate 24 hours a day. Highly automated machinery is used. Shutdowns can be expensive.
