Abstract


ENGLISH ABSTRACT: This paper aims to guide those in supply chain management who make decisions on selecting factories, transportation modes, and the number of products to be manufactured. Solutions can be found through development of an optimisation model, using mixed-integer programming. Because green supply chain issues have become important, and new legislation has to be taken into account, carbon emissions costs must be included in the total costs of the supply chain, as in the optimisation model presented, which then has the ability to minimise total costs and to provide solutions that are both cost-effective and environmentally friendly.

AFRIKAANSE OPSOMMING: Die doel van hierdie artikel is om leiding te verskaf aan diegene in voorsieningskettingbestuur wat besluite neem aangaande die keuse van fabrieke, vervoermetodes en die aantal produkte om te vervaardig. Oplossings kan gevind word by wyse van n optimiseringsmodel wat gemengde-heeltalprogrammering gebruik. Aangesien groen of te wel omgewingsvriendelike aspekte belangrik geword het en nuwe wetgewing in ag geneem moet word, moet die koste van koolstofemissies in die totale koste van die voorsieningsketting in berekening gebring word, soos wat in die optimiseringsmodel wat voorgehou word inderdaad gebeur. Sodoende kan n oplossing gevind word wat nie alleen koste-effektief is nie, maar ook omgewingsvriendelik.
