The relevance of the subject matter derives from the need to select the most effective technical solution at the stages of pre‐design studies and design of irrigation systems when performing innovative projects. The purpose of this study is to develop a decision support system (DSS) that would serve as an analytical and advisory tool for conducting complex research at the stages of pre‐project preparation and design of irrigation systems. The leading approach underlying the solution of the subject matter is the functional modelling methodology integration definition for function modelling (IDEFo). This article presents the architecture of the software product, which shows the main subsystems of the DSS and reflects their interrelations. The implementation of the DSS in the form of a software product based on the provisions of the recommendations will automate the process of selecting alternatives (analogues) for elements of irrigation systems in specific conditions and provide information support for decision‐making at the stages of pre‐design studies and design, and also increase quality control and improve efficiency of managerial decision‐making by 10–15% and reduce the total cost of organizing pre‐design studies and designing irrigation systems by 3–5%. © 2020 John Wiley & Sons, Ltd.

在预设计研究和基于IDEFo功能建模方法的灌溉系统设计阶段开发决策支持系统*

主题的相关性源于需要在进行创新项目时的灌溉前设计研究和灌溉系统设计阶段选择最有效的技术解决方案。这项研究的目的是开发一个决策支持系统（DSS），作为在项目前准备和灌溉系统设计阶段进行复杂研究的分析和咨询工具。解决该主题的主要方法是功能建模的功能建模方法学集成定义（IDEFo）。本文介绍了软件产品的体系结构，该体系结构显示了DSS的主要子系统并反映了它们之间的相互关系。根据建议的规定，以软件产品的形式实施DSS，将自动为特定条件下的灌溉系统要素选择替代方案（类似物），并为预警阶段的决策提供信息支持设计研究和设计，还将质量控制和管理决策效率提高10％至15％，并将组织设计前研究和灌溉系统设计的总成本降低3％至5％。分级为4 +©2020 John Wiley＆Sons，Ltd. 还将质量控制和管理决策效率提高10％至15％，并将组织设计前研究和设计灌溉系统的总成本降低3％至5％。分级为4 +©2020 John Wiley＆Sons，Ltd. 还将质量控制和管理决策效率提高10–15％，并将组织设计前研究和设计灌溉系统的总成本降低3–5％。分级为4 +©2020 John Wiley＆Sons，Ltd.
