CHEMICAL ORDERING SYSTEM

To provide a chemical ordering system for facilitating reduction of carbon dioxide emissions.SOLUTION: A chemical ordering system for managing order placement of chemicals to be injected into service water, includes chemical monitoring means, replenishment time prediction means for predicting an ordering time of chemicals on the basis of a monitoring result acquired from the chemical monitoring means, and ordering time determination means. The ordering time determination means determines a first ordering time to be recommended and first transport means to be recommended on the basis of a replenishment time predicted by the replenishment time prediction means, choices about transport means of the chemicals, the amount of carbon dioxide to be discharged by the transport means, and a transport speed of the transport means.SELECTED DRAWING: Figure 1 【課題】二酸化炭素排出量の削減を容易にする薬品発注システムを提供すること。【解決手段】薬品発注システムは、用水に注入する薬品の発注を管理する薬品発注システムであって、薬品監視手段と、薬品監視手段から取得した監視結果に基づいて薬品の発注時期を予測する補充時期予測手段と、発注時期決定手段とを備え、発注時期決定手段は、補充時期予測手段が予測した補充時期と、薬品の輸送手段についての選択肢と、輸送手段が排出する二酸化炭素の量と、輸送手段の輸送速度と、に基づいて、推奨する第１の発注時期と、推奨する第１の輸送手段とを決定する。【選択図】図１
