Integration of mathematical and information modelling approaches for decision support in african animal production and health systems

摘要

The use of tools such as mathematical models, databases and expert systems has an important role to play in the provision of relevant expertise and technologies to farmers in developing countries. However, these tools are often deficient when used in isolation; their full potentials can only be realized through integration. The integration of tools is not, in itself, sufficient to ensure the effective and efficient use of information. The specific information needs of different decision makers will vary, and one cannot afford to create distinct systems for each type of user. These differences may be more apparent than real, representing different routes through the same information structure. The concept of information integration describes an attempt to organize data and knowledge in a single cohesive unit. The resultant complexity requires the provision of tools which provide appropriate access to, and navigation within, the information structure. Such an integrated information system is currently under development for the domain of African livestock production. It is anticipated that a system will enhance the diagnosis, treatment and management of cattle disease, increase understanding of animal nutrition and allow health and productivity records to be more effectively maintained. The paper illustrates the types of integration described above through the development of an integrated information system.
