Study on the Expert System for Agricultural Drainage Planning

本研究旨在探讨专家系统在灌排复垦工程领域应用的可能性。在本研究的第一年，用FORTRAN语言为主体系统开发了围垦区径流量计算和调节池出口设计的计算机程序。第二年，通过对国家项目区多个填海地块的调查，对填海区域排水规划的生成规律进行了分类，构建了专家系统推理引擎的骨架。最后一年，建立了围垦区排水规划总体专家系统的流程图，并对各子系统进行了FORTRAN编程或借助一些专家壳纳入主专家系统。由于整个系统无法在个人计算机系统中构建，因此以手册的形式给出了一些子系统，这些子系统显示了专家系统主体部分的使用方法。从这个意义上说，研究中开发的专家系统从实际使用的角度来看是没有价值的。这主要是由于硬件可用性的限制。将该系统转换为其他高端个人电脑或工作站，将有助于在当地办公室使用该专家系统进行项目设计。

This research has aimed for the presentation of possibility of applying the expert system in the field of the irrigation, drainage and reclamation engineering.In the first year of this research, computer programs for calculating runoff from the reclaimed area and designing the outlet of regulating pond has been developed with the FORTRAN language for the main frame system.In the second year, with the investigations of many reclamation plots in the national project areas, the production rules for drainage planning in the reclaimed area have been classified and the skeleton of the inference engine for the expert system has been constructed.In the final year, the flow chart of the total expert system of drainage planning for reclamation area has been built up and each sub-systems has been coded in the FORTRAN or included in the main expert system with the help of some expert shells. Because the entire system could not have been constructed in the personal computer system, some sub-systems have been given as a form of manuals which show the method of utilizing the main frame part of the expert system.In that sense, the expert system developed in the research is not valuable from a viewpoint of actual use. This has been mainly due to the constraint for hardware availabilities. Transformations of this system to other high-end personal computers or work stations will contribute the use of this expert system in the local office for project designing.
