A mixed integer linear programming approach to minimize the number of late jobs with and without machine availability constraints

Detienne, Boris - In: European Journal of Operational Research 235 (2014) 3, pp. 540-552

This study investigates scheduling problems that occur when the weighted number of late jobs that are subject to deterministic machine availability constraints have to be minimized. These problems can be modeled as a more general job selection problem. Cases with resumable, non-resumable, and...

A new algorithm for generating all nondominated solutions of multiobjective discrete optimization problems

Kirlik, Gokhan; Sayın, Serpil - In: European Journal of Operational Research 232 (2014) 3, pp. 479-488

Most real-life decision-making activities require more than one objective to be considered. Therefore, several studies have been presented in the literature that use multiple objectives in decision models. In a mathematical programming context, the majority of these studies deal with two...

Cost to produce and deliver cellulosic feedstock to a biorefinery: Switchgrass and forage sorghum

Griffith, Andrew P.; Haque, Mohua; Epplin, Francis M. - In: Applied Energy 127 (2014) C, pp. 44-54

Switchgrass and forage sorghum have both been proposed as potential candidates for high yielding, dedicated energy crops. This research was conducted to determine and compare the costs to produce and deliver switchgrass and forage sorghum biomass under the assumptions that the biomass would be...
