【摘要】 本文阐述了在微机GW286EX上建立的蛋、肉鸡场建设项目经济评价系统,包括经济评价定量分析子系统和关于鸡场生产建设的数据咨询子系统。系统在多用户多任务的XENIX—V操作系统支持下运行,应用INFORMIX数据库管理系统和C语言编程。实际案例运行表明,该系统设计合理、可靠,与已有的系统比较,在使用功能、软件设计、模型化和评价计算方法上均有特点。更多还原

【Abstract】 In the woke of the develpment of agricultural construction, the feasibility studies of projects was more paid attention to by the departments of agricultural management. The economic appraisal is a very important part of the feasibility studies as synthestic analysis of quantity. For the purpose of providing a implement of the economic appraisal with high efficiency and high quality, we have developed this EAS on the microcomputer GW286EX. The EAS include two subsystems, one is the quantitative analysis subsystems for economic appraisal of a new project, another is a data consultation subsystems on production and fundamental construction of the chicken farm. The EAS is running under the XENIX-V operating systems with multi-user and multi-task, and the use of the INFORMIX data base management systems and c-language for making the programs of EAS. Running by way of the practical example shows that the EAS is better in design of the systems. It is the first time in the agricultural management of China on this study of EAS.To compare the EAS with the other, it has more characteristics, e.g. on the functions and software’s design and modeling and method of the appraising camlation.更多还原
