Simulation of fruit pallet movement in the port of Durban: A case study

Self Cite

(1), pp. 55-72. After a brief introduction to the problem, two models (a single-commodity graph theoretic model and a multi-commodity mathematical programming model) are derived for determining the maximal weekly flow or throughput of fresh fruit through the South African national export infrastructure. These models are solved for two extreme seasonal export scenarios and the solutions show that no export infrastructure expansion is required in the near future -observed bottlenecks are not fundamental to the infrastructure and its capacities, but are rather due to sub-optimal management and utilisation of the existing infrastructure.

Apart from work in the mining industry during the 1950s, the first real Operations Research (OR) group in South Africa was established at CSIR in the early 1960s. Those initially involved in this group played a significant role in establishing OR at various universities in South Africa. The OR group at CSIR did, however, continue and today the group still exists. This paper presents a brief history of this group and endeavours to provide a glimpse of some of the projects conducted over the many years since its establishment.

“…• Simulation models were developed for Fresh Produce Terminals in the Cape Town [12] and Durban [17] ports to analyse these terminals in more detail. Both simulation models were built by final year Industrial Engineering students from the University of Stellenbosch and are described in more detail in a subsequent paper [1].…”

This paper gives an overview of a study that was done on the logistics infrastructure used by the South African fruit industry. Given the increasing production and export volumes, development of new markets and the shortage of logistics infrastructure capacity during peak seasons, the SA fruit industry identified the need to investigate the optimal usage of existing infrastructure on a national level and to make recommendations with regards to the development of additional infrastructure. Some background on the SA fresh fruit industry and its export supply chain are provided. This is followed by a description of the four project phases and their deliverables. The paper is concluded with the key findings of the study.
