The four Futuro case studies (Futuro No. 000, Corfu-Futuro, Donaldson-Futuro, Munich-Futuro) presented in this journal document conservation approaches to plastic buildings and elements – case, glass-reinforced (GRP) sandwich panels. They contribute the definition of general approaches, at same time reveal knowledge gaps related their individual histories necessity a framework for managing inte...

In this paper, we considered a deterministic inventory model with time-dependent demand and time-varying holding cost where deterioration is time proportional. The model considered here allows for shortages, and the demand is partially backlogged. The model is solved analytically by minimizing the total inventory cost. The result is illustrated with numerical example for the model. The model ca...
