Esta dissertação propõe e valida uma metodologia prática para o dimensionamento do stock remanescente de materiais exclusivos durante a fase de fim do ciclo de vida de um produto, com o objetivo de reduzir custos e mitigar o risco de obsolescência. Esta abordagem engloba uma árvore de decisão para classificar casos operativos, uma tabela de decisão que aplica percentagens de ajuste do stock final em função de fatores críticos,
cálculos de equilíbrio de stocks e de lotes mínimos (adaptados ao horizonte temporal do processo de descontinuação) e um critério de arredondamentos que adequa as quantidades teóricas obtidas à realidade prática dos fornecedores. Esta metodologia parte do stock remanescente associado à última encomenda sugerida pelo sistema de planeamento SAP e aplica percentagens operacionais para redução do mesmo,
definidas a partir da análise de dados históricos e do trabalho com responsáveis das áreas envolvidas.
A sua aplicação ao caso de estudo do binóculo Ultravid 10x25 Leathered Black (406-07) evidenciou reduções do custo total original de cerca de 14,7% pela estratégia de entradas múltiplas e cerca de 15,0% com LTB. Isto demonstra que é possível conciliar a redução de custos com a diminuição do risco de obsolescência.
This dissertation proposes and validates a practical methodology for sizing the residual inventory of exclusive parts during a product’s end-of-life phase, aiming to reduce costs and mitigate obsolescence risk. The approach includes a decision tree to classify operational cases, a decision table that applies percentage-based adjustments to final stock according to critical factors, stock equilibrium and minimum-lot calculations adapted to the discontinuation time horizon, and a rounding rule that converts theoretical quantities into supplier-feasible practical values. The method is based on the residual stock remaining after the last order suggested by the company’s ERP system SAP and applies operational reduction percentages defined from historical data analysis and collaboration with area managers. The application to the case study of the Ultravid 10x25 Leathered Black binocular (406-07) led to total procurement cost reductions of approximately 14,7% with a multiple-entry strategy and about 15,0% under a last-time-buy strategy, demonstrating that cost reduction can be reconciled with reduced obsolescence risk.
