استخدام برمجة الاهداف الخطية في تخطيط ونقل الماء الصالح للشرب في مدينة السماوة

The purpose of the study is using the linear goal programming to planning and transportation the suitable drinking water in areas of samawa city and areas surround it.The study including (30) areas has been nutriting from three mainTanks in city , some of areas nutrited by pipes and other areas that nutrited by tankers . goal programming model has been bulit for this problem includes (30) decision variables, (80) deviational variables , (40) constraints and (5) goals , and because of the model is large we solve it by using winQSB program. Also using important techinque in goal programming so called (sensitivity analysis) ,and this techinque makes the goal programming model mor flexibility through change of composition of model ; the constraints , goals , variables and priorities , and this gives new result according to the change which produced from the using this techinque , and this flexibility give the decision maker the ability to find the best and closed possible solutions to the problem.
