On Dual Based Lower Bounds for the Sequential Ordering Problem with Precedences and Due Dates
The Sequential Ordering Problem (herewith, SOP) with precedence relationships was introduced in Escudero (1988), and extended to cover release and due dates in Escudero and Sciomachen (1993). It has a broad ra...
