Abstract Most of the territory of the Arab Republic of Egypt in the dry and semi-dry climate, the region suffers from a lack of water resources, and that the Egyptian economy depends on agriculture, so it is the consumption of large quantities of water in agriculture. And the building of the agricultural development operations based on increasing the efficiency of the irrigation process, which depends on the choice of the most appropriate technical specifications of each component of the irrigation control head, which in turn leads to increased productivity. The selection of the best technical specifications for each of the components of the irrigation control head is one of the fundamental processes that lead to an increase in the efficiency of the irrigation system and therefore increase productivity. And where there are many types and models for each of the components of the drip irrigation control head (the pump, filters, Fertigation unit, valves) that agriculture began in Egypt depends on technological development such as the use of expert systems and programs that rely on artificial intelligence to support decisionmaking in this area. The objectives of the study The study aimed to build and evaluate an expert system to select the most appropriate technical specifications of each component of the drip irrigation control head. The construction of expert system called ”TSDI-ES” to choose the most appropriate technical specifications of the components of the drip irrigation control head. And this is a simple and flexible system where the user can modify the inputs at any time without any impact on the results of the program and to help in the process of selecting the technical specifications for each component of the drip irrigation control head using machine language Visual Basic. 52 SUMMARY AND CONCLUSIONS Samar A. Mohamed (2017), M.Sc., Fac. Agri., Ain Shams Univ. Materials and Methods used can be summarized as follows: 1) Collected a large database for each of the components of the irrigation control head and through the companies listed in the Egyptian market. 2) The composition and compilation of expert program called (TSDI-ES) to select the most appropriate technical specifications of each component of control head unit in the drip irrigation network using the language of Visual Basic 2013. The proposed program has been explained and its contents Reference Data (information site - the characteristics of the soil, climate data - cropping patterns - Irrigation options), as well as all the EQUATIONS and rules used in the estimation of variables of irrigation management. 3) The program has been validated by IMOC-ES rule based program to calculate the irrigation requirements and selection of appropriate irrigation control head components. 4) The evaluation of the TSDI-ES program through holding accounts and applying the experience to the Al-Nubaria farm. 5) Three types of crops (Mango- Orange- Lemon) were considered . The obtained results showed that: 1) The ability to choose the most appropriate technical specifications of each component of the drip irrigation control head unit. 2) The results showed the possibility of application of expert systems based on a database, particularly where the proposed expert system features ”TSDI-ES” easily design, relying on the database without the need to use additional design programs. 3) The possibility of the use of the program ”TSDI-ES” needs assessment of different crops with high accuracy. 53 SUMMARY AND CONCLUSIONS Samar A. Mohamed (2017), M.Sc., Fac. Agri., Ain Shams Univ. 4) The possibility of amendment and addendum in the program inputs at any time as well as easy to deal with the program and does not require the existence of a scientific background-friendly with the program. 5) The possibility of introducing a database more than the technical specifications for each of the components of the irrigation control head. 6) All results of equations using the program ”TSDI-ES” were close to those calculated through the Excel program and also with the results of the calculated manually. The recommendations of this study from the previous results can be recommended that the proposed program ” TSDI-ES” is the addition of new scientific knowledge in the application of techniques of expert systems in the field of engineering the irrigation under the Egyptian conditions and that the accuracy of the selection of the most appropriate technical specifications of each component of the drip irrigation network, leading to greater efficiency in the use of irrigation water and therefore increase productivity meanwhile. Expert systems can be an alternative choice for the private sector due to difficulties encountered in finding the expert person at all times and everywhere and high costs of expert persons. Computer programs known as expert systems are believed to be the best fitting method for the solution of complex. Problems like selection of components of irrigation network. In this study following suggestions can be made: Better economic decisions will be taken within a short time. Likelihood of making mistakes will be eliminated by the use of the program and thus damages that will be caused by mistakes will be prevented. 54 SUMMARY AND CONCLUSIONS Samar A. Mohamed (2017), M.Sc., Fac. Agri., Ain Shams Univ. With the development of this program, selection of such properties of pumps as cables, electrical organs etc. will be possible. This expert system will help pump dealers in selecting the suitable pump from among pump brands with different technical properties. The database of this program can be expanded by entering the technical properties of pumps from different firms. |
