Question
JIT/ Lean (20 Points): The Farm-4-Less tractor company produces a grain combine (GC) in addition to both a large (LT) and small size tractor (SM). Its production manager desires to produce to customer demand using a mixed-model production line. The current sequence of production, which is repeated 20 times during a shift, is SM-GC-SM-LT-GC-SM-LT-SM. A new machine (GC, LT, or SM) is produced every three minutes. Based on this information, answer the following questions: 1. (7 points) How long does it take for the repeating production cycle to be completed? How long is the working duration of a shift at Farm-4-Less? How many of each type of machine does Farm-4-Less produce in a shift?Explanation / Answer
Quantity of X in each container = 10
Time required to process each unit of X = 0.5 minutes
Thus, time required to process each container = 0.5 x 10 = 5 minutes
Hence 1 container gets released as output every 5 minutes
Since each container waits 0.5 hours or 30 minutes before it gets processed , number of in process containers = 30 minutes/ 5 minutes = 6 numbers
Since safety stock factor is 20%, quantity of safety stock required = 20% of 6 = 1.2 containers
Therefore , total in process inventory = 6 + 1.2 = 7.2 containers ( 8 rounded to next higher whole number )
Hence, number of Kanban cards required = 8 numbers
NUMBER OF KANBAN CARDS REQUIRED = 8
NUMBER OF KANBAN CARDS REQUIRED = 8
