“…In this case, terminals act as sinks too, where the optimal turnover calculated by step 1 is now treated as demand. To ensure that every source point will be assigned to one sink, the objective function has to be extended by a binary decision variable f ik (5), leading to a similar objective function as presented by Ranta (2002). Constraint (6) satisfies demand (d k termplant ).…”

The promotion of electric energy production from solid biomass by the Austrian government has lead to a boom in the construction of new combined heat and power plants. The current total demand for wood chips in the research area for energy purposes is 70 400 m 3 of loose volume chips per year. The expected increase in demand due to these new plants is more than 4 times greater than current demand: up to 302 700 m 3 of loose volume per year. Even if the energy wood feedstock potential is satisfactory, the design of the supply chain is still unresolved. The aim of this study is to give decision-makers a base for further development. To accomplish this, we designed and tested four different supply scenarios: one for 9 plants and one for 16 plants. The scenarios were developed using a combination of geographic information systems (GIS) and linear programming methods. The results indicate that direct transport of solid fuel wood as round wood and chipping at the plant is the cheapest supply system with a resulting cost of 5.6-6.6 EUR/m 3 loose. Using harvesting residues can only be recommended for large plants because of poor fuel quality. In this case, residues would be chipped at or near the landing, piled and transported via self-loading trucks at a cost between 8.4 and 9.1 EUR/m 3 loose. In order to meet increasing demand and to ensure a continuous supply, especially during the winter and spring seasons it is necessary to optimize the supply chain by including storage terminals. However, using terminals and increased demand both lead to higher logistical costs. For example, if the total volume is handled via terminals, the average supply costs including storage will increase by 26%. Higher demand increases the costs by 24%.

“…Where to locate power plants, and how to supply forest biomass to each plant is a problem that is commonly approached through location-allocation modelling, where the global objective was to minimize the total transport cost, typically expressed as the product of demand and distance [14]. The use of geographical information systems (GIS) supports analysis of spatial relationship between locations of forests, plants and transport infrastructure.…”

Controlling moisture content and truck configurations to model and optimise biomass supply chain logistics in Ireland

Highlights A linear programming model that optimises wood biomass supply in Ireland. It uses MC to determine harvesting, chipping, storage and transportation costs. It analyses two supply chain scenarios and two truck configurations. Low wood MC increases supply cost due to longer transport distances. Optimal truck loads can be achieved by controlling wood MC. AbstractIn the coming years, Ireland will continue to face an increasing demand for wood biomass as a renewable source of energy. This will result in strained supply/demand scenarios, which will call for new planning and logistics systems capable of optimizing the efficient use of the biomass resources.In this study, a linear programming tool was developed which includes moisture content (MC) as a driving factor for the cost optimisation of two supply chains that use short wood and whole trees from thinnings as material feedstock. The tool was designed and implemented to analyse the impact of moisture content and truck configurations (5-axle and 6-axle trucks) on supply chain costs and spatial distribution of the supply materials. The results indicate that the inclusion of wood chips from whole trees reduces the costs of wood energy supply in comparison with only producing wood chips from short wood to satisfy the demand, with 9.8% and 10.2% cost reduction when transported with 5-axle and 6-axle trucks, respectively. Constraining the MC of the wood chips delivered to the power plant increases both transport and overall supply chain costs, due, firstly to an increase in the haulage distance and secondly, to the number of counties providing the biomass material. In terms of truck configuration, the use of 6-axle trucks resulted in a 14.8% reduction in the number of truckloads and a 12.3% reduction in haulage costs in comparison to the use of 5-axle trucks across the MC scenarios analysed.
