Metacomputing refers to the coordinated use of a pool of geographically distributed high-performance computers. The EU projects PHASE and MICA, presented in this paper, are settled in the eld of application speciic metacomputing combining high-performance computing expertise and industrial requirements.

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...
