A computer-implemented method for optimizing distribution of incentive-budget for additional time interval allocation in a multi-week work schedule is provided herein. The computer-implemented method comprising: (i) training a model to forecast future net staffing; (ii) generating a multi-week work schedule; (iii) using the model to forecast for each time interval a net staffing value; (iv) classifying time intervals as understaffed; (v) displaying the understaffed time intervals to suggest agents to take as additional time interval; (vi) providing a tier incentive structure and an incentive budget to be updated by a user; (vii) training the model to forecast a degree of elasticity of agents demand for each time interval based on historical agents schedule changes; and (viii) calculating a combination of incentives of each tier of the tier incentive structure in the incentive-budget to accommodate understaffed time intervals and maximize agents demand for time intervals based on forecasted degree of elasticity.
