某施工项目需要组合钢模,组合钢模周转利用率为85%,现租用钢模5000m2,月租金4元/m2;由于加快施工进度,实际周转利用率达到90%;该项目材料储备资金是根据日平均用量、材料单价和储备天数(即从采购到进场所需要的时间)计算的。上述任何一个因素的变动,都会影响储备资金的占用量,现已知钢材的储备资金计划与实际情况如表7-31所示。
表7-31 钢材储备资金计划与实际对比表
项目 | 单位 | 计划 | 实际 | 差额 |
日平均用量 材料单价 储备天数 储备金额 | t 元 天 万元 | 50 4000 10 200.00 | 60 4200 8 201.60 | 10 200 -2 1.6 |
根据表中数据,分析日平均用量、单价和储备天数等因素的变动对钢材储备资金的影响程度,并指出影响储备资金的关键因素。 |
