Introduces the OSSA problem and a GPA policy achieving 4/3-approximation for online allocation of unknown shared supply under fixed costs and lost sales, with matching lower bounds and a forecast-robust extension.
Proposition 10.Consider the predictions {ˆs, { ˆDi}i∈[n]} for the given OSSA instance with prediction error η=|s−ˆs|+ Pn i=1 |Di − ˆDi| ≥0

Introduces the OSSA problem and a GPA policy achieving 4/3-approximation for online allocation of unknown shared supply under fixed costs and lost sales, with matching lower bounds and a forecast-robust extension.
