Title | Forecasting contractor performance using a neural network and genetic algorithm in a pre-qualification model |
---|---|
Untitled | |
Abstract |
Purpose – This paper seeks to introduce an evolved hybrid genetic algorithm and neural network (GNN) model. The model is developed to predict contractor performance given the current attributes in a process to pre-qualify the most appropriate contractor. The predicted performance is used to pre-qualify the contractors. Design/methodology/approach – Hypothetical and real-life case studies from projects executed in the Gaza Strip and West Bank were collected through structured questionnaires. The evaluation of the contractor's attributes and the corresponding actual performance of the contractor in terms of time, cost, and quality overrun (OR) were collected. The weighted contractor's attributes were used as inputs to the GNN model. The corresponding time, cost, and quality ORs for the same cases were fed as outputs to the GNN model in a supervised learning back propagation neural network (NN). (The … |
