Abstract:
Determination of optimum comparison of suppliers with humanitarian supply chain criteria is a main challenge to relief organizations. Although the investigations in this area have ignored the delivery reliability of suppliers up to now, this parameter has a significant effect on humanitarian supply chain performance. In this paper, a mathematical model regarding delivery performance and delivery reliability of suppliers for selecting suppliers of relief items is proposed. The proposed model is formulated in a framework agreement format. We employed time window to deliver the essential items for the purpose of considering the supplier reliability. Also, we assumed that the distribution time of delivery lead time is Gaussian distribution. In the presented numeric example, the value of cost function is increased, but with considering the supplier reliability parameter, the expecting behavior of system becomes more stable. In fact, this increment of cost function is a payoff for increasing the reliability of system. The main goal of the model is to select the optimal combination of suppliers and allocation items in different scenarios. So, in the proposed model, this goal is achieved with higher quality. The real case study of selecting water suppliers in Mazandaran province of Iran with real features and scenarios is considered to evaluate the performance of the presented model. To perform the experiments accurately, we did sensitivity tests on our model's parameters, and also we investigated the scalability of the proposed model.
