Does processing time means the time needed to produce an intermediate product or time needed to produce a finished goods, acounting recovery and losses?
Can I ask let think in reality. The first product will need 400 seconds cuz each station needed waiting for the precedent ones to start working. From the 2nd product, every 100 seconds there will be a product go out of the assembly line. Therefore, we cannot meet the desired output per day (Cuz 400 seconds instead of 100 seconds for the first product each day). Am I wrong?
Hi this video helped me a lot I just want to ask questions Is it necessary to start letter "A" as ther first task by the first station or is it dependent on what letter has the longest process time? Thank you
First you have to start with the processes who doesn't have predecessor (here it is A and B), if there are multiple such processes, then choose the one with the highest process time ( here we have selected A) and then keep going.
if a process is having both machine and man time combined for example process A is having man time 5 sec and machine time 15 sec in total 20 secs , man will be waiting for the 15 sec for next process
Hi, this video helped me a lot. Question, is there anytime when none of them are eligible? like say for instance, B was not eligible in station 2? is this possible?
do you mean, "is that possible that non of the processes that doesn't have any Predecessor?" In short, there will be one or two or even more processes that shouldn't have any predecessor while the rest of them are had it. It all depends on the case
@@AdiTV-r5o Thanks for your reply. I actually meant, if its possible to have a process that does have a predecessor to not have any "proses ready" or in other words a "feasible task". You know how you list the proses ready in station 2 for C. C has a proses ready of B and the only feasible task is B, what if B was not possible? Does this ever occur that there is no feasible task? I hope i explained myself good enough. Thanks for your help.
@@alin8387 If there are no feasible task, then if you learnt from "Project Management" course, that particular task/stasion (or whatever you want to call it) which has no feasible task, may occur on some condition. But in term of production planning and inventory control (PPIC), such case is rarely happened because what we try to find out here is the assembly line which is consider as the main process. so if theres any process/step which has no feasible task, wouldn't be count in this term. it depends on what are you going to do from such case. Well I'll make it easy.. the case that you've been asking, are happening in real situation, but depends on what are you trying to observe, it may be count or not.
