PROBLEM TO BE SOLVED: To reduce waste loss of products.SOLUTION: A production management system according to the present invention has a management unit for managing at least information on temperature detected as change of growth environment for crops, and a crop yield prediction unit for predicting crop yield of a crop on the basis of a model indicating the amount of photosynthesis of the crop with respect to temperature and a model of the amount of growth of the crop with respect to the temperature.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】生産物の廃棄ロスを削減すること。【解決手段】生産管理システムは、農作物の生育環境の変化として検出された気温の情報を少なくとも管理する管理部と、気温に対する農作物の光合成量を示すモデルと、気温に対する前記農作物の生育量を示すモデルとに基づいて、農作物の収量予測を行う収量予測部と、を備える。【選択図】図１
