Designing and mathematical modelinggreen supply chain network by collection centers in the area of environment

Nowadays, Economic systemsplayan important rolein the environmental field. Along with the rapid change in global manufacturing scenario, environmental and ocial issues are becoming more important in managing any business. Increasing pressures and challenges to improve economic and environmental performance have caused developingcountries in general in particular to consider and start implementing green supply chain management. GreenSupply ChainNetwork DesignandManagementare an approach to improve performance of the process and products according to the requirements of the environmental regulations. It is emerging as an important approach which not only reduces environmental issues but also brings economic benefit to manufacturers. Green supply chain management has a significant influence to reduce environmental risks. Choosingthe suitable supplier is a key strategic decision for productions and logistics management on the supply chain management.The purpose of this studyis to describe the green supply chain management, and determining the allocation of products between plants,collection centersandthe effect of green supply chain management to the cost of the system is investigated Inthispaper,Green supply chain managementwithmultipleand conflictingobjectivessuch asreducing costsincreasingcustomer service levelsand ncreasedflexibility(accountability), respectivelybyprovidingmathematicalmodelforoptimal allocationofmanufacturingproductstomarketdemand.Inthe event of aproblemreturnthemto factorypaysthecollection centers.Also, GreenSupply ChainNetwork Designthat includes several manufacturing plants, collection centers, rket demand and production, with the aim of minimizing the total cost of the chain to be considered.
