    ENGLISH ABSTRACT: South Africa is classified as a key player in the global wine industry. The wine industry however is under threat as it is experiencing different challenges which it must overcome. These challenges are placing the wine industry under great financial pressure. This leads to the following key research question for this study: How can an approach be developed for supporting better long-term capacity planning decision making in the wine supply chain? A Pragmatism research philosophy was used for this project which led to an inductive research approach being followed since the project was not based on a pre-existing theory, but a new theory was developed by analysing data. The research method that was mainly used for the project is mixed method seeing that the required data was obtained by means of structured interviews and physical observations. A combination of case study and design science research strategy was used. Orange River Cellars (Oranje Rivier Wyn kelders-OWK) was used as a case study which contributed to the development and testing of the framework. The focus of the literature study was on capacity planning decisions of wine cellars within a supply chain network. The aim was to get a clear understanding of the supply chain networks and current research regarding capacity planning and supply network design in the wine industry. The main databases that were used consisted of Scopus and Google Scholar. It was found that limited research has been done on capacity planning, facility relocation and supply chain network design regarding the wine industry. Thus, the gap was identified as the lack of capacity planning of supply chain networks and facility relocation in the wine industry. Next the conceptual framework was developed to capture the considerations and the approach for facility relocation planning and capacity planning in the wine industry. The framework aids in obtaining a good understanding of supply chain network seeing that with each stage a better understanding of the supply chain network is formed. For this framework the profitability of the cellars is first determined. With that information the most economical allocation of capacity in the supply chain is then determined as well as the relocation cost and capacity of the cellars that are no longer profitable. The framework was then applied to the OWK case study. This case study consisted of a wine corporation that is situated in the Northern Cape. OWK has 6 cellars that receive grapes to produce either juice or wine. The amount of grapes received by the cellars are decreasing each year which caused OWK to ask the question of whether all the cellars are still profitable. The framework concluded, that for the OWK case study, Cellar5 is not profitable anymore. The framework further recommends that Cellar5 be closed and the supply of grapes moved to Cellar4. The yeast tanks should also be moved to Cellar4 seeing that all the cellars experience a peak in the supply of grapes at approximately the same time during the harvest.
