Modeling a bi-objective newsboy problem with compound discount condition, considering Warehouse space and budget constraints and solving it by different approaches of MODM problems

The newsboy problem is considered as a single period problem which is very common in our real life. This paper study the newsboy problem considering the discount constraint including quantity and incremental and also warehouse space and budget constraint with two objectives of profit and service level maximizing. These objectives are designed by an integer non - linear model. This model is solved by using GAMS software and various multi-objective techniques considering this assumption that each product distribution is uniform.Also comparison of methods has been done in tow forms of statistical comparison and multiple decisions.
