Balancing and lot-sizing mixed-model lines in the footwear industry

This report describes the full research proposal for the project \Balancing and lot-sizing mixed-model lines in the footwear industry", to be developed as part of the master program in Engenharia Electrotécnica e de Computadores - Sistemas de Planeamento Industrial of the Instituto Superior de Engenharia do Porto. The Portuguese footwear industry is undergoing a period of great development and innovation. The numbers speak for themselves, Portugal footwear exported 71 million pairs of shoes to over 130 countries in 2012. It is a diverse sector, which covers different categories of women, men and children shoes, each of them with various models. New and technologically advanced mixed-model assembly lines are being projected and installed to replace traditional mass assembly lines. Obviously there is a need to manage them conveniently and to improve their operations. This work focuses on balancing and lot-sizing stitching mixed-model lines in a real world environment. For that purpose it will be fundamental to develop and evaluate adequate effective solution methods. Different objectives may be considered, which are relevant for the companies, such as minimizing the number of workstations, and minimizing the makespan, while taking into account a lot of practical restrictions. The solution approaches will be based on approximate methods, namely by resorting to metaheuristics. To show the impact of having different lots in production the initial maximum amount for each lot is changed and a Tabu Search based procedure is used to improve the solutions. The developed approaches will be evaluated and tested. A special attention will be given to the solution of real applied problems. Future work may include the study of other neighbourhood structures related to Tabu Search and the development of ways to speed up the evaluation of neighbours, as well as improving the balancing solution method.

Standarização no IKEA Industry de Paço de Ferreira

Standarização de um posto de trabalho não é mais que definir o melhor método de trabalho que vai ser seguido por todos os operadores que trabalham no mesmo. Uma vez definido esse método, é importante para uma empresa ter noção da produtividade que podem alcançar, dado que pode ser retirado a partir deste método, e é no seguimento disto que surge o estudo dos métodos e tempos, mais concretamente o estudo dos tempos por cronometragem. A aplicação deste estudo foi despoletada pela necessidade do IKEA Industry de Paços de Ferreira, em dar o próximo passo na standarização dos seus postos de trabalho, área a área, e da necessidade de terem uma pessoa em cada área que analisa-se o trabalho que estava a ser feito e calcula-se o tempo de cada rotina. Neste documento, é realizada uma interligação entre os conceitos teóricos que o método exige, como todo o conjunto de fórmulas, restrições, análises e ponderações, com o contexto laboral onde o mesmo foi aplicado e a estratégia desenvolvida pelo IKEA na realização do estudo. O estudo dos métodos e tempos por cronometragem, de todos os métodos existentes, pode ser considerado o mais completo e complexo, uma vez que é mais que observar, registar e retirar uma média ponderada das observações. Este método baseia-se num modelo matemático, que interliga uma série de conceitos e que tem sempre o operador em consideração, seja na avaliação e análise das tarefas que requerem mais esforço dos mesmos, físico ou psicológico, seja em termos de tempos de pausas pessoais que a lei obriga a que as empresas deem. Este detalhe, neste método, é de grande importância, uma vez que a standarização é sempre vista pelos operadores como uma punição. As desvantagens deste método estão no grau de conhecimento e capacidade de observação exigidas ao analista para o executar. Melhor dizendo, um analista que vá executar este trabalho necessita observar muito bem a rotina de trabalho e conhecer onde começa, acaba e tudo o que a ela não pertence, antes de começar a registar seja que tempos forem. Para além disso, é exigido ao analista que perceba o ritmo de trabalho dos operadores através da observação dos mesmos, de modo a que ninguém seja prejudicado. E por fim, é necessária uma grande disponibilidade da parte do analista para retirar o máximo de observações possíveis. Com o intuito de facilitar esta análise, o IKEA Industry criou um ficheiro que compila toda a informação relacionada com o método, e uma explicação de todos os parâmetros que o analista necessita ter em atenção. Esta folha de trabalho foi validada à luz do método, como é possível verificar no decorrer do documento. Um detalhe importante a referir, é que por muito fidedigno que seja este método, tal como qualquer método de standarização, a mínima alteração da rotina de trabalho invalida de imediato o tempo total da rotina, tornando necessário realizar o estudo novamente. Uma vantagem do documento criado pelo IKEA, está na rápida adaptação a estas alterações, uma vez que, caso seja acrescentado ou removido um elemento à rotina, basta alterar o documento, observar e cronometrar os operadores a executar esse novo elemento, e quase automaticamente é definido um novo tempo total padronizado na rotina. Este documento foi criado para fins académicos e de conclusão de um grau académico, mas o estudo quando aplicado na empresa deu origem a contratações, o que só por si mostra as vantagens e impacto que o mesmo pode ter em contexto laboral. Em termos de produtividade, uma vez que a sua aplicação não foi executada a tempo de ser estudada neste documento, não foi possível avaliar a mesma.

Enhancement of an implemented rating model and impact on existing risk management processes: A hands-on approach from financial supplier risk management within the automotive industry

The purpose of this paper is to conduct a methodical drawback analysis of a financial supplier risk management approach which is currently implemented in the automotive industry. Based on identified methodical flaws, the risk assessment model is further developed by introducing a malus system which incorporates hidden risks into the model and by revising the derivation of the most central risk measure in the current model. Both methodical changes lead to significant enhancements in terms of risk assessment accuracy, supplier identification and workload efficiency.

Strategy of Logoplaste in Mozambique's flexible plastic packaging industry

Logoplaste is a specialist in operating in-house industrial sites for manufacturing rigid plastic packaging containers. In developing countries, especially in Africa, the low income of consumers does not allow a widespread adoption of products typically sold in rigid plastic containers. In these countries the flexible packages are usually adopted as they allow for better ratios of cost/litter of product, particularly in smaller packages. Should Logoplaste offer this type of technology in order to expand into developing countries?

Hotel industry: An answer to the emerging trends on the global demand side of tourism

This dissertation studies essentially how Millennials are changing the hotel industry, in the sense that new trends are emerging with this generation and hotels need to respond accordingly, in order to survive within their competitive industry. Emphasis is also given to Asian travellers, as the enlargement of these countries’ middle class populations is predicted, therefore making Asian travellers a valuable target for the hotel industry. To successfully target this segment, hoteliers need also to consider the cultural differences and aspirations that come together with the Asian travellers, and appropriately adapt their offer to them. I will then redirect this study to the city of Lisbon, the Portuguese capital, to analyse if Lisbon’s four and five-star hotel managers are aware of the new market trends, and to understand how they are changing their hotels in order to make them more attractive to Millennials and Asian travellers. Using a sample of 12 hotels (four and five-stars ratings), I have concluded that, although there is a notable undergoing process of adaptation to these guests, there is a long way ahead in order for Lisbon’s hotels to entirely please and retain millennial guests.

Escalation of conflict in FMCG industry: A negotiation case

This work project develops a case-study to be used in Negotiation courses, both in Masters programs and in executive education workshops. The case-study is based on a real-life negotiating situation in Belgium between Unilever, the second largest Fast Moving Consumer Goods (FMCG) company in the world, and Delhaize, one of the most important Belgium’s retailers, with a significant international presence. We also present an analysis of the negotiation based on relevant literature. First, a brief literature review is presented about how to deal with multiple-issue negotiations and how to deal with processes of escalation of conflict. These concepts are then applied to the analysis of the case-study.

IPO impact on industry incumbents

The creation of an innovative company is suggestive of change in an industry. To test that change this paper tests the impact of IPOs on industry incumbents. IPOs are found to happen in industries that exhibited positive abnormal returns for up to 5 years before the IPO date. The IPO date is found to coincide with the end of that industry abnormal return profile. This paper suggests this evidence is consistent with the IPO acting as mechanism of enforcing market efficiency at the industry level.
