A production planning problem for a supply chain of multi - location plants with fuzzy unit production costs , fuzzy capacities and fuzzy demands is mainly investigated 摘要描述了模糊單位生產(chǎn)成本、模糊生產(chǎn)能力以及模糊需求下的分布式多工廠供應(yīng)鏈批量生產(chǎn)計(jì)劃問題。
We find that when unit selling price , unit inventory disposal cost , or unit shortage cost is larger , or when unit production cost is appropriate , or when production setup cost is smaller , demand forecasting becomes more important 研究發(fā)現(xiàn)需求預(yù)測在以下情況中十分重要: ( 1 )當(dāng)單位售價(jià)、或單位存貨處理成本、或單位商譽(yù)損失成本較大時(shí), ( 2 )當(dāng)單位生?成本在某適當(dāng)值時(shí), ( 3 )不生?前置成本較小時(shí)。
