This paper discusses capacity expansion problems for telecommunication network facilities, based on fuzzy dynamic programming. Cost functions, demand functions and so on usually cannot be defined clearly. This paper represents undefined factors by fuzzy numbers with triangular membership functions (TFN). Multiplication or division of TFN does not give rigid TFN, but we approximate them to TFN for ease of calculation. [In Japanese.]
