Optimization excess capacity

The decision described above is commonly termed the newsboy model. The optimal capacity decision can be obtained by identifying two costs the marginal cost of excess capacity Q and the marginal cost of capacity shortage Q. In the example above, the marginal cost of excess capadty is...

Moisture Content/Field Capacity Within the vadose zone, moisture content is important since microbial growth is limited by excessively wet or dry soil. Moisture content, expressed as a percentage of the field (or holding) capacity, indicates the ratio of moisture to air in the soil. The recommended range for optimal growth is between 40 and 70%. 

Fused silica capillaries are almost universally used in capillary electrophoresis. The inner diameter of fused silica capillaries varies from 20 to 200 pm, and the outer diameter varies from 150 to 360 pm. Selection of the capillary inner diameter is a compromise between resolution, sensitivity, and capacity. Best resolution is achieved by reducing the capillary diameter to maximize heat dissipation. Best sensitivity and sample load capacity are achieved with large internal diameters. A capillary internal diameter of 50 pm is optimal for most applications, but diameters of 75 to 100 pm may be needed for high sensitivity or for micropreparative applications. However, capillary diameters above 75 pm exhibit poor heat dissipation and may require use of low-conductivity buffers and low field strengths to avoid excessive Joule heating.

If demand happens to be greater than K for a tariff equal to a, the tariff should be increased to equalize demand and supply at the capacity level K. For the demand DHigh, the optimal tariff is c. For the Dhigh demand case, a tariff below c will induce excess demand and call for a non-price mechanism to pick out customers - preferably those with the highest willingness to pay.
