畢業(yè)設(shè)計(jì)論文基于線性規(guī)劃的最優(yōu)路徑設(shè)計(jì)

1、基于線性規(guī)劃的最優(yōu)路徑設(shè)計(jì)[摘要]各個(gè)領(lǐng)域中的大量問題都可以歸結(jié)為線性規(guī)劃問題尤其在物流管理活動(dòng)中有大量的規(guī)劃問題如網(wǎng)絡(luò)配送中的運(yùn)輸規(guī)劃問題它屬于線性規(guī)劃問題的特例運(yùn)輸問題存在多種解法目前計(jì)算機(jī)應(yīng)用普及用一般的解線性規(guī)劃的軟件來(lái)解運(yùn)輸問題是一條較好的途徑根據(jù)調(diào)查表明近幾十年來(lái)線性規(guī)劃在各個(gè)行業(yè)中都得到了廣泛的應(yīng)用而且運(yùn)輸問題的模型不單只是適用于一般意義上的物資運(yùn)輸問題更重要的是它適用于一切道路網(wǎng)絡(luò)問題因此。[關(guān)鍵詞]線性規(guī)劃Floyd算
