    摘要: In terms of flexibility and product variety in lot-sizing systems of crisp cases, the
    average demand of per unit of time (mj), the relative duration of setup (qj), and the unit
    cost of production (cj) are considered. Instead of using the usual method that the mj, qj,
    and cj in the total cost function are respectively fuzzified by the triangular fuzzy numbers
    to derive fuzzy total cost, in this paper, we construct three different intervals to include
    mj, qj, and cj, respectively, and then consider the fuzzification of the system from these
    three different intervals directly. And finally the fuzzy total cost is obtained. By applying
    respectively the signed distance and centroid method for defuzzification, two different
    total cost functions are obtained, and thus the respective optimal solutions are computed.
