i have a system with two sets of machines , the first set contains 10 machines with a processing time of 40min ( they don't start at the same time to prevent having 10 outputs at the same time , there's is time gap of 4 MIN between the starting time of each machine ) each of these identical machines gives cans as an out put ( a can each 40 min) , these machines feed the second set which contains 5 identical machines , each of them need 5 cans from the first set to start working , each of these machines give a can each 15 min as an output , the 5 cans of the input get consumed in one hour , which means 5 cans of input xill give us 4 cans in the output , there's no condition on what machines from set 1 should feed a specific machines from set 2 , ( the first ten mahines can feed any of the second five machines according to availability) , my question is , how can i setup that ? and how can i setup the system in way that feeding the second set of machines in order ( the first five cans coming from the 1st set go to the first machines of the 2nd set , the second five cans go to the second machine...etc)
