| Summary: | Warranty is a bond that is given to products that require companies to
assign compensation to consumers if the product fails to function normally after
the purchase of usage during the specified warranty period. Offering warranty
will generate expense which is called warranty cost. Therefore, estimation of
warranty cost is very important to be done. This paper will studying two
dimentional warranty that is limited by time and usage, with non-renewing free
replacement warranty policy for non- repairable product. Calculation of expected
warranty costs using a two-dimensional joint distribution of variable distribution
and usage time, in example bivariate distribution. Modeling of failure to follow
the bivariate Pareto distribution, with parameters obtained through MLE
method. In calculating the expected cost of warranty policies FRW, used type of
convolution integral and Laplace transform that use software to get the solution,
as well as in the calculation of the expected refund policy PRW.
