Models for Evaluating the Set-up for Loading Ledge Recycling within IKEA (English)
Abstract [en]

Reverse logistics is getting more and more attention both from companies and the public. It is an area with the possibility for companies to do good in the eyes of the public. This work focus on the return system of a one-way handling material called the loading ledge. The loading ledge is developed by IKEA as a substitute for the EUR-pallet in transports from suppliers with a long distance and even flow and in transports from suppliers with short distance and uneven flow. The loading ledge is made out of 100 % recyclable plastic.

The purpose of this work is to find the most efficient set-up for recycling of loading ledges within IKEA on a European level from a transport and handling point of view considering aspects like cost, environment, time and, from an administrative point of view, user-friendliness.

Who will the participants of the set-up be, where will they be located, which transports are needed and which income and costs does the set-up generate, are questions that will be answered. An optimisation model of the problem is modelled using the modelling language AMPL and solved by CPLEX, a computer program for solving linear integer optimisation problems.

The result of this work is five suggestions for the set-up found using the optimisation model. The set-ups differ in number of participants, transports and costs. Common for all set-ups is the use of a Polish supplier. Otherwise the set-ups differ depending on where the sorting is performed. When performed at the distributions central the set-ups uses Sweden and Poland as locations for recycling stations and when sorting is performed at the recycling station the set-ups uses Germany and Poland as locations for recycling stations. The set-ups are presented graphically along with suggestions for implementation.

Key words: logistics, reverse logistics and optimisation.
