The Economic Appraisal Systems (EAS) for Constructing the Egg-meat Chicken Farm

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.
