process time distribution

Hello Everyone

I am working with process modelling , I am facing problem while creating the different process times. in the below figure it shows the process flow in which there are two different products(TYPEA and TYPEB) from the feeder which flow through different stations at the end of the flow there is a packing station in which the two products have different time for the packaging. for TYPEA it should take process time of 50secs and TYPEB should take a process time of 90 secs. can any one help me to solve this issue.
