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

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

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.
