It overcomes the disadvantages that orthodox analyzing method wants a great deal of stylebook to ensure probability distributing , big calculation , and ignoring fuzzy effective factor , and that different nonlinear total cost curves need to find different statistical forecasting model 克服了傳統(tǒng)分析方法需要大樣本量,確定概率分布、計(jì)算量大、不考慮模糊影響因素的缺點(diǎn)??朔瞬煌姆蔷€性總成本曲線需要尋求不同的統(tǒng)計(jì)預(yù)測(cè)模型的缺點(diǎn),通過累加生成技術(shù),將非線性總成本問題統(tǒng)一到gm ( l )模型上。
