The purpose of this paper is to develop a model for selecting the best contractor in the Gaza Strip using the Artificial_x000D__x000D_
Neural Network (ANN). The contractor’s selection methods and criteria were identified using a field survey. Fifty four engineers_x000D__x000D_
were asked to fill a questionnaire that covers factors related to the selection criteria of contractors practiced in Gaza Strip. The_x000D__x000D_
results shows that the dominant part of respondents (91%) confirmed that the current awarding method "the lowest bid price" is_x000D__x000D_
considered one of the major problems of the construction sector, "award the bid to the highest weight after combination of the_x000D__x000D_
technical and financial scores" represented 50% of the respondents. The criteria weights were determined based on Relative_x000D__x000D_
Importance Index (RII . Ninety-one tenders(13 projects) were used to train and test the ANN model after re-evaluating the_x000D__x000D_
contractors depend on the weights of factors to select the best contractor who achieves the highest score. Neurosolution software_x000D__x000D_
was used to train the models. The results of the trained models indicated that neural network reasonably succeeded in selection the_x000D__x000D_
best contractor with 95.96% accuracy. The performed sensitivity analysis showed that the profitability and capital of company are_x000D__x000D_
the most influential parameters in selection contractors. This model gives chance to the owner to be more accurate in selecting the_x000D__x000D_
most appropriate contractor.
