Bibliography: p. 121-131. / The primary aim of this paper is to attempt to apply the flexible specialisation (FS) methodology to the furniture industry in the Western Cape. As described in detail in the following section, the gains from employing this approach include "the conceptualisation of industrialisation as a locally embedded process, and the focus on network and on technological capability as essential elements in this process" (Aeroe, 1992:16). A positive approach is then used to assess which aspects of the Western Cape furniture industry (if any) are similar to the industrial organisational structure which has been termed the small firm variant of FS. The fieldwork for the empirical part of the case study was carried out on a sample of 20 furniture manufacturing concerns drawn from three clusters of furniture enterprises in Epping, Lansdowne and Blackheath. The criterion for the selection of these research areas was the existence of a critical mass of sectorally concentrated firms agglomerated within a geographically compact area. A key objective was to attempt to isolate the influence of the variable "locality" on other variables such as the extent of cooperation, firm performance and strategies and supplier relations, inter alia. Finally the normative implications of this variant are examined. Do features in the Western Cape industrial landscape exist which suggest the potential for development of regional industrial clusters along FS lines? In order to conduct a case study broadly within the FS framework, it is necessary to first review the literature and extract testable hypotheses. Firstly the general literature on the FS small firm variant is reviewed. Then a survey of FS case studies of the furniture/woodworking sector is presented. The next phase is a detailed perspective on the South African furniture industry given as a background to the empirical study which follows.

The origins of the retail furniture industry commenced with family run stores, traditionally known as "momma and poppa" stores as they were entrenched in certain families. A feature of these stores was that they traded with people that they knew and enjoyed a great deal of loyalty. As the businesses grew there was a need to supply furniture to their clientele with a facility to repay the full price over a number of months. Such arrangements were typically concluded on trust as the customers were well known by the owners. The industry has evolved from this type of operation to a multi-billion rand industry. In terms of the size of business that is transacted and the size of the major furniture retailing organisations, it is simply not possible to continue doing business in accordance with the same ethos that prevailed during the early days. However, given the decentralised nature of the industry, the philosophy of knowing their customers has prevailed and this notion of wanting to conduct business on this basis has largely been responsible for a many critical functions remaining under the control of the individual stores within the broader network. In terms of the high volume of transactions that are currently concluded, it is extremely difficult to ensure that the application of policy and risk-based decisions are made on a consistent basis. From a cost effectiveness and productivity point of view, it is not possible to realise efficiencies and economies of scale that could be enjoyed if certain business processes were centralised. The intention of this research is to evaluate how the introduction of automated decision making business processes can contribute towards managing the organisation's exposure to risk with the view to achieving required levels of organizational performance and also sustainable value creation through a customer-centric philosophy. / Thesis (MBA)-University of Natal, Durban, 2003.

Descrevemos o sistema de produção de uma fábrica de móveis característica do Polo Moveleiro de Votuporanga, com ênfase no setor de corte da matéria-prima, e propomos um algoritmo para resolver o problema de corte de estoque considerando a minimização do número de objetos cortados e do número de ciclos da serra. A ideia principal do algoritmo proposto (AFM-P) consiste em adicionar ao problema, de forma dinâmica, restrições que imponham uma frequência mínima para a utilização de um dado padrão de corte. A cada iteração uma solução é gerada e no final do algoritmo existe um conjunto de soluções que são analisadas segundo critérios de dominância. Realizamos um estudo computacional utilizando os dados reais da fábrica visitada para analisar o comportamento do AFM-P. O estudo computacional mostrou que através do algoritmo proposto é possível encontrar soluções próximas e, na maioria das vezes, melhores que a prática da indústria tomada como estudo de caso / In this work we study the two-dimensional cutting stock problem originated from a furniture industry. We describe the production system of a characteristic furniture plant situated at Votuporanga Regional Center and we propose an algorithm to solve the cutting stock problem taking into account the minimization of the number of objects and the number of saw cycles. The main idea of the algorithm (AFM-P) is adding to the problem, in a dynamic way, constraints that impose a minimum frequency to the use of a given cutting pattern. At each iteration a solution is generated and at the end there is a set of solutions that are analyzed according to dominance criteria. The AFM-P algorithm is tested using data from the furniture plant visited. The computational study shows that using the proposed algorithm it is possible to find solutions that are close the ones used in the industry practice and, in most cases, better than theirs
