Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The South African Navy (SAN) intends to reinstate Naval Station Durban
(NSD) as a fully operational support base for a new class of Offshore Patrol
Vessels (OPV’s) which the SAN intends to purchase. These acquisitions must
be seen against the background of strategic and political considerations in
general, and in particular threats to South Africa’s maritime security, due
to the possibility of the piracy, along particularly the West African coast,
reaching our territorial waters. The aim of this thesis is the development
of a cost-optimization model, intended to provide optimal locations for the
SAN’s support facilities, given the SAN’s operational obligations, present and
future. In the first part, a literary review of facility location formulation and
strategic management principles is an attempt to lay the foundations for the
proposed model. The review of this literature is primarily based on extracts
of the comprehensive research of other authors. Consequently, the research
problem was contextualized and classified as a hierarchical location-allocation
problem. The second part of the thesis aims to describe the SAN’s environment
from a maritime security perspective. Within this framework, formulation
was identified and modified to develop a theoretical mechanism to solve the
research question. The final part will see the application of the developed
model to a case study specific to the situation of the SAN. Validation of the
inputs and the model itself proceeded in conjunction with the application of
the model. The results and the model itself were validated through visual
inspection and independent mathematical validation. This thesis comes to
the conclusion that the SAN cannot cost-effectively meet its future obligations
by splitting its maintenance capability between Naval Base Durban (NBD)
and Naval Base Simon’s Town (NBS). Future research may build upon the
results of this thesis in order to facilitate a more comprehensive optimization
of preventative networks. / AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse Vloot (SAV) beoog om die vlootstasie in Durban weer
op te gradeer na ’n volwaardige vlootbasis vir die beoogde aanskaffing van
’n nuwe klas van patroleringsvaartuie. Die motivering vir die opgradering
van Durban kom uit dieper strategiese en politieke behoeftes maar word tans
toegeskryf aan plaaslike bedreigings van seerowery en die gevolglike verkryging
van nuwe patrollievaartuie om hierdie bedreiging, onder meer, te bekamp. Die
doel van hierdie meesters tesis, is om ’n koste optimerings model te vind,
of te ontwikkel, wat optimale liggings vir ondersteunings fasilitieite sal lewer,
gegewe die toekomstige of huidige verpligtinge van die SAV. Die eerste gedeelte
van hierdie tesis bevat ’n literatuuroorsig van fasiliteitsligging-formulering en
strategiese bestuursbeginsels. Hierdie literatuuroorsig beoog om die grondslag
vir die voorgestelde model te lê. Die oorsig van sodanige literatuur is hoofsaaklik
gebaseer op uittreksels uit veelomvattende opsommings deur ander outeurs.
Gevolglik is die navorsingsprobleem gekontekstualiseer en geklassifiseer as ’n
hiërargiese ligging-toekenningsprobleem. Die tweede deel van die tesis beoog
om die omgewing van die SAV vanuit ’n maritieme sekuriteitsperspektief te
beskryf. Binne hierdie raamwerk is formulering geïdentifiseer en só gemodifiseer
om ’n teoretiese meganisme te ontwikkel om die navorsingsvraag op te los.
Die finale deel pas die ontwikkelde model op die spesifieke situasie van die SAV
toe. Validasie van die insette sowel as die model self is gedoen in samewerking
met die toepassing van die model. Die resultate tesame met die model self is
deeglik bekragtig deur visuele inspeksie en onafhanklike wiskundige validasie.
Hierdie tesis het tot die gevolgtrekking gekom dat die SAV nie koste-effektief
aan sy toekomstige operasionele verpligtinge sal kan voldoen met die verdeling
van sy onderhoudsvermoë tussen ’n vlootbasis in Durban en Simonstad nie.
Toekomstige navorsing kan op die resultate van hierdie tesis bou ten einde ’n
meer omvattende optimalisering van voorkomende instandhoudingsnetwerke
te fasiliteer.
