英文摘要 | We cannot manage today’s agribusiness without agrichemicals because they increase the harvest yield and save the labor force. However, agrichemicals applied carelessly not only remain with crops at a high concentration but also pollute soil. Since its pollution can influence future managements, taking account of residual pesticides is so essential for programming application amounts of agrichemicals. In this paper, we propose an agrichemical application amount programming problem were we deal with one crop race and multiple agrichemicals. The model is designed to minimize the maximum value among ratios of residual pesticides with the crop to their standard values. We reflect the fact that a labor time for cultivation and harvest vary according to application amounts of agrichemicals to its constraints. |
