Iprojekthi 1: Umatshini opheleleyo wokulinganisa ngokuzenzekelayo kunye nokupakisha
张。预算:iseti enye yomgca wokupakisha imalunga ne- 28000-40000美元
2.产量:60袋/清水X 60分钟X 8小时X2个更换/天X 300天/年x200g = 3456吨/清水
3.Ukuchaneka: ngaphakathi + -1g
4.Inani labasebenzi: i- 5 yabasebenzi / i- shift x2 / usuku = abasebenzi abayi-10 / usuku

Iprojekthi 2: Ubunzima bencwadi epheleleyo kunye nokupakisha
(umlinganisi wetheyibhile yobunzima bencwadi, ukutywina ibhendi ngokutywina ngesandla ingxowa)
张。预算:isitheibhuli somthwalo + webhendi = $ 3000- $ 5000
2.Ukukhupha kunye nenani labasebenzi: Ukutya okwenziwa ngesandla, ubunzima, ukugcwalisa, ukudinisa abasebenzi abane-4-5, isantya si malunga neebhegi ezili-10 ngomzuzu, ukuuma kosuku olunye kuyimfuneko yi-11.52 iqhosha, ukuba omnye uhluza, ukuba abasebenzi abangama-24 ukuya kwengama-30, ukuba ezimbini zityhafisa zifuna abasebenzi abangama-48-60。
3.Ubungqina: ngaphakathi + -2g

Uvavanyo olupheleleyo:
Ibhajethi: Iprojekthi 2 ayibizi xa kuthelekiswa neProjekthi1 (umahluko weedola ezingama-25000- $ 35000)。
2.Ukuchaneka: Iprojekthi 1 yonga imveliso iitoni ezili-17-20 ngonyaka xa kuthelekiswa neprojekthi2
3.Umsebenzi: Iprojekthi 1 gcina abasebenzi abayi-38-50 ngonyaka, ukuba umvuzo omnye wabasebenzi ungama-6000 eedola ngonyaka, kwiprojekthi 1, enokugcina i-228000- $ 30万ngonyaka。

Isiphelo:Umatshini opheleleyo wokulinganisa ngokuzenzekelayo kunye nokupakisha kubhetele kunobunzima obupheleleyo kunye nokupakisha
