When supply and demand are tight, prices are mainly related to supply, demand and variable costs.
Taleizadeh et al. (2011) have formulated Multiple-buyer multiple-vendor multi-product multi-constraint supply chain problem with stochastic demand and variable lead-time: A harmony search algorithm.
Given that energy balances were characterized based on monthly estimations, the method is appropriate for sizing installations with variable monthly demands and variable monthly panel tilt (for seasonal estimations).
Liu (2006) used GP technique to determine long-run and short-run maximum profit, the highlighted point of this paper is demand and variable costs per unit of production as a range are considered.
This minimization can be achieved through power-factor correction, utilizing stand-by options, communication and monitoring with the smart grid, taking advantage of off-peak charging and operation, on-demand and variable processing speed semiconductors, or switching to a lower power mode.
"We don't believe every spot is created equal," Payal says as we head for the door, describing future plans to use demand curves and variable pricing to help her studios grow.
If a firm's previous funds have been successful, it can generally earn higher revenues with the new one by setting higher fees, demanding more variable compensation and raising more capital.
First, a robust optimal design problem is described by using the minimax regret criterion and considering the hierarchical relationship among design variables, energy demands, and operation variables, which is followed by a solution method.
However, to reduce the number of demand locations and variables for our POM method (see "Solution approach 2 POM approach"), we opt to merge the list of most populated areas with the highest density, thus obtaining a total list of 16 states.
In addition, the method accounts for hydrological variables (dynamic water table level and temporal variation), soil variables (infiltration parameters, surface storage capacity, surface impermeability), hydraulic variables (head losses in pipes, flow demand) and economic variables (energy costs, pump and pipe costs).
