Abstract The purpose of this research is to consider the dispatching and scale problem of airline unit load devices (ULDs) with consideration of service levels and violation days. A service level is specified to control the number of days that the ULD safety stock requirement can be violated. The network model and solution algorithm are developed with parallel computing. We find that our solutions are an improvement over the current solutions employed by the studied carrier from 31.89% to 33.01% for different safety stock levels. We also conclude that the studied carrier should set the service level to 90% as the general standard for stations considering the tradeoff between the number of ULDs required and the violation days.
Highlights We develop a mathematical model for dispatching airline unit load devices (ULDs). The service levels which control the number of days that the ULD safety stock can be violated is considered. A time-space network technique and a chance-constrained technique are combined to develop the model. The original network is decomposed into four subproblems and a repetitive solution algorithm developed to find solutions. The managerial implications of the specification of different violation days and service levels are discussed.
