Laws of large numbers for fuzzy random variables have been led to the need in order to ensure consistency in estimation problems of statistical inference for fuzzy probability models. In the last 20 years, there have been increasing interests in laws of large numbers for sums of fuzzy random variables. But for weighted sums of fuzzy random variables, only a few results have been known until now. Thus it is one of significant problems how we can generalize laws of large numbers for sums of fuzzy random variables to the case of weighted sums. The purpose of this thesis is to contribute to this concerns.
