A Multi-item Capacitated Lot-sizing Problem with backlogging, safety stocks and outsourcing in a closed loop supply chain

چکیده مقاله

Capacitated Lot-sizing Problem (CLSP) has received an increased
attention from the research community due to its inherent applicability
to real-world problems. This paper proposes a new mixed integer
programming model for Multi-item Capacitated Lot-sizing Problem
(MCLSP) with backlogging, lost sales, safety stocks, demand shortages
and outsourcing in a closed loop supply chain. The aim of this paper is
to highlight, once more, the powerfulness of how the mathematical
formulation of the Capacitated Lot Sizing Problem can be easily
adapted to solve further practical closed loop supply chain applications
especially related to manufacturing and production environment.
Mathematical formulations and computational experiences of solving
the proposed model with Lingo solver will be provided to support these
statements.
