Weibull CDF parameters estimation with suspencions

Hi everyone,
I'm starting to learn something about Weibull CDF, therefore I can't still solve the following problem.
I have data about failure items (the same type of item) in 3 inspections:
201 failures over 360 items at 350 hours;
450 failures over 1160 items at 600 hours;
773 failures over 1280 items at 1000 hours.
How can I setup the solution, taking into account or not of the suspencions (or right censored items), in order to find the scale and shape parameters of a two-parameters Weibull function as shown below?
Thank you in advance.
