- W2899174004 abstract "This paper considers a let scheduling problem for highway construction projects under an anticipated funding scenario. Highway construction projects typically require large-scale funds, and rely on the revenue from state and federal funding sources. The revenues mainly come from transportation-related taxes and fees. Such revenues can radically change over time due to the uncertainty of economy, and the Department of Transportations (DOTs) need to cope with such funding changes to avoid any overdraft or unhealthily excessive cash balances. A mathematical optimization model is proposed as a means of decision support to determine how to revise the let schedule when the future revenue is expected to change. A case study of the North Carolina DOT (NCDOT) is presented to demonstrate the application of the proposed model, where major types of projects having construction costs more than $10 million are analyzed. A formula to evaluate the impact of changing let dates is presented and a constrained logistic model that estimates the construction costs of individual projects is proposed. As a recommendation for utilizing the proposed model, three practical ways are summarized including the rolling-horizon-based let scheduling, funding change analysis, and the assessment of funding project risks." @default.
