Bye, guys. are struggling with this technology exercise, where I am experiencing some problems:
data a real time of replacement equal to 12 min,
a dense replacement time of 18 min,
and a coefficient r of 0.3
indicate which of the following statements is true:
1 the minimum cost is 42 min
2 the economic duration is 28 minutes
3 the maximum productivity duration is 28 min
4 the minimum cost is 14 min
5 the maximum productivity duration is 42 min
then we start from the economic life, where I know her like this:
te=(1/n - 1) x (t(u) + c(ut) / c(p) )
t(u)= machine stop time for tool change
c(ut)= tool cost
c(p)=workplace cost-
Since I do not know c(ut), c(p) the economic duration I exclude it. Am I wrong? Then I don't know how to continue.
