چکیده:
In this study, supplier and carrier selection and order allocation are considered to go for joint decision-making. To this end, some criteria including cost, quality, delivery, resilience, social responsibility and supplier profile are determined to select the weight of each supplier by AHP. Then, multi objective mathematical model is developed to select the appropriate supplier and carrier and allocate orders of multi product with different discount levels in each period by suitable carriers to each supplier. The objective functions in this study are minimizing cost, delivery and the number of defective items, and maximizing the efficiency of suppliers. Moreover, some constraints such as inventory capacity, shortage capacity, number of vehicle and breakdowns of them etc. are applied in this model. Finally, this model is solved by augmented ɛ-constraint method for determining pareto-optimal solution.

Then, multi objective mathematical model is developed to select the appropriate supplier and carrier and allocate orders of multi product with different discount levels in each period by suitable carriers to each supplier.
Due to the increasing importance of supply chain management, recent approaches have been aimed at developing the models that can simultaneously look at procurement supplier, carrier selection, and order allocation problem.
, 2011) studied a multi-period purchasing problem in which a buyer procures a single product from a single supplier considering economies of scale in purchasing and transaction costs along with supply chain disruptions.
This study, for the first time, considers the supplier and carrier selection and order allocation for multi products with different carriers as well as discount level in each period.
4. (View the image of this page)Proposed model The objective of this study is to propose a multi-criteria decision-making approach based on supplier and carrier selection and order allocation.
Hence, the weights calculated in AHP method are used in multi objective mathematical model for order allocation of suppliers and selection of the suitable carrier for products where discount rate and rejection rate are assumed.
In this study, multi product multi period supplier selection and order allocation of the multi objective model are presented where some limitations are proposed for buyer and supplier, and transportation vehicle are considered as a problem.
In this study, multi-objective mixed integer mathematical model was investigated for order allocation of each product to each supplier in discount level by selecting proper transportation vehicles.
