【摘要】 决策支持系统(Decision Support System ,简称DSS)是辅助决策者通过数据、模型和知识,以人机交互方式进行半结构化或非结构化决策的计算机应用系统。它是管理信息系统(MIS)向更高一级发展而产生的先进信息管理系统。它为决策者提供分析问题、建立模型、模拟决策过程和方案的环境,调用各种信息资源和分析工具,帮助决策者提高决策水平和质量。带约束的多目标进化算法,就是把带约束的多目标进化算法转化成一串个无约束的多目标规划的方法,国内外求解约束规划的方法,一般可分为三种途经。本文就结合算法采用Asp.net技术,Acess2000数据库,C#编程技术,同时参考中华人民共和国国家内分泌营养治疗总局糖尿病营养推荐标准以及平衡膳食宝塔结构及中国居民膳食营养标准,针对营养保健需求,开发出了基于浏览器/服务器(Browser/Server, B/S)架构的膳食营养决策支持系统。合理膳食对患有糖尿病者的患者具有良好的治疗作用,糖尿病人作为一种特殊的人群,由于和普通人吃的食物不一样,因此就需要有一个合理的食谱,要更加注意膳食的结构合理,营养学家的配餐是一个很繁琐的过程,既耗时又容易出错,而且必须由具有一定经验和特长的专家才能完成。所以开发出了基于浏览器/服务器(Browser/Server, B/S)架构的膳食营养决策支持系统,并给出了带约束的多目标进化算法在系统的具体实现过程,最后的配餐方案和专家提出的建议十分吻合,得出的配餐效果相当理想。更多还原

【Abstract】 Through data, models and knowledge ,Decision Support System (decision support system called DSS) assists decision-makers. To human-computer interaction, its approach is semi-structured or unstructured decision-making computer applications. It is the management information system (MIS) to a higher level generated by the development of advanced information management system. It provides decision-makers to analyze problems, build models, simulate the environmental decision-making processes and programs, and call various information resources and analytical tools to help decision-makers to improve decision-making level and quality.Constrained multi-objective evolutionary algorithm is to convert constrained multi-objective evolutionary algorithm into a string of non-binding multi-objective programming approach for solving constrained planning methods at home and abroad, and can be divided into the following three kinds of passing through.In this paper, combining algorithm uses asp.net technology, spl2000 database, c # programming techniques, while making reference to The People’s Republic of China State Administration of endocrine treatment of diabetes, nutrition, nutritional standards and recommended a balanced diet structure and the Chinese pagodas dietary nutrition standards for nutrition and health needs, develop out based on browser / server (Browser / Server, B / S) architecture, diet nutrition decision support system.Reasonable diets have good therapeutic effect for people with diabetes. Diabetes as special people, because they eat food which is not the same as ordinary people, therefore they need to have a reasonable diet. We should pay more attention to the structure of a reasonable diet, the nutritionist catering is a very tedious process, it is not only time-consuming but also error-prone, and it must have some experience expert to complete. Therefore, developed diet nutrition decision support system which based on browser / server (Browser / Server, B / S) architecture, and gives constrained multi-objective evolutionary algorithm in the system realization process, the final programs are consistent with expert catering recommendations ,it gets satisfactory Catering results.更多还原
