Sustainability in Supply Chain Management Aggregate

Jan 25 2016 0183 32 Aggregate planning a fundamental decision model in supply chain management refers to the determination of production inventory capacity and labor usage levels in the medium term Traditionally standard mathematical programming formulation is used to devise the aggregate plan so as to minimize the total cost of operations...
