Technically, yes. But are often used interchangeably if your system is working ideally. Takt time is desired and Cycle time is real/actuality (may be different than takt time slightly).
Very good question. Let us say C=10 and a task takes 14 seconds. In that case, you will have to create two parallel stations with double cycle time of 20 seconds. Each of those parallel stations will do exactly the same thing and produce two units in 20 seconds (or effectively, produce a unit every 10 seconds on an average) and will keep the assembly line humming.
Hi sir, please help me balance for this lesson : Target/day : 4,500 pcs (8hrs). And only have 4 tasks such as : A(18sec)--->B(22sec)--->C(12sec)--->D(9sec). Thank you
28800/4500=6.4 sec ( takt time) 61/6.4=9.5~10 stn required I assume the task A=18Sec,B=22 sec ,C=12 sec & D =9 sec can not be broke down. In this case to meet the demand 4500, A=18/6.4 ~ 3 operator required B= 22/6.4~ 4 op req C= 18/6.4 ~3 op rq D= 9/6.4~ 2 op rq So totally 12 op required...
If a task is ready for allocation and even if it is NOT the most eligible "ready" tasks, you can allocate it for higher efficiency. Example: Suppose you have 20 seconds available at a particular work station and two tasks are ready for allocation requiring 19 seconds and 50 seconds respectively. Obviously, task taking 50 seconds should be allocated first (assuming longest operation time heuristic). However, it will not fit in that station as it has only 20 seconds remaining. However, the task taking 19 second will fit...so, bend the rule and allocate that task. Hope this helps.
I wish you would read the description. "This video has been prepared to assist my students at Indiana University of Pennsylvania (IUP), located in Western Pennsylvania near Pittsburgh (USA)."
