Using truck-inventory-cost to obtain solutions to multi-period logistics models

Ali, Agha Iqbal; O'Connor, Debra J. - In: International Journal of Production Economics 143 (2013) 1, pp. 144-150

The antithetic opposition between the cost of inventory and the fixed cost of transportation, which leads to multiple alternate near-optima, can be a primary contributor to the computational intractability of the mixed integer program for a two-echelon multi-period distribution system. To...

The Impact of Distribution System Characteristics on Computational Tractability

Agha, Iqbal; O'Connor, Debra J. - Department of Economics and Accounting, College of the … - 2008

Mathematical programming models that seek optimal design and operational plans for distribution systems can be computationally intractable. This paper examines the extent to which distribution configuration and demand characteristics affect the ease of obtaining an optimal solution. Problem...

A mathematical formulation and complexity considerations for the blocks relocation problem

Caserta, Marco; Schwarze, Silvia; Voß, Stefan - In: European Journal of Operational Research 219 (2012) 1, pp. 96-104

The blocks relocation problem (BRP) may be defined as follows: given a set of homogeneous blocks stored in a two-dimensional stock, which relocations are necessary to retrieve the blocks from the stock in a predefined order while minimizing the number of those relocations? In this paper, we...

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...

Energy balance optimization of sugarcane crop residual biomass

Sartori, Maria Márcia Pereira; Florentino, Helenice de … - In: Energy 32 (2007) 9, pp. 1745-1748

This work presents a mathematical model for helping mills choose sugarcane varieties for planting. It maximizes crop … planting area. For this full zero-one linear programming techniques were proposed. The model is viable for choosing sugarcane … varieties that would benefit sugarcane production and industrial systems, by reducing crop residue and increasing final energy …
