Labor costs are one of the largest expenses of retail companies. This work develops a decision support tool to manage staffing levels and schedule working shifts, balancing the sales contribution of employees with salary costs. We extend recent empirical studies that estimate the impact of...

This paper revisits the airline schedule-buffer choice problem analyzed by Brueckner, Czerny and Gaggero (2020) using a simpler model where the random shocks influencing flight times are discrete rather than continuous. The analysis yields closed-form solutions for the flight and ground buffers...

Container liner shipping is the primary mode of moving manufactured products across continents. Partly due to inherent uncertainties at sea and ports, the liner shipping industry has long had a notorious reputation of schedule delays and unreliable on-time performance. This paper formulates a...

Just-in-time scheduling has become ubiquitous in the service industries. While effective in reducing staffing level, hence labor cost, the potential impact of just-in-time scheduling on workers' productivity and the firm's revenue is not well understood.
