  2. Base load - Wikipedia

    en.wikipedia.org/wiki/Base_load

    The base load [2] (also baseload) is the minimum level of demand on an electrical grid over a span of time, for example, one week. This demand can be met by unvarying power plants [ 3 ] or dispatchable generation , [ 4 ] depending on which approach has the best mix of cost, availability and reliability in any particular market.

  3. EPANET - Wikipedia

    en.wikipedia.org/wiki/EPANET

    The package also supports the simulation of spatially and temporally varying water demand, constant or variable speed pumps, and the minor head losses for bends and fittings. The modeling provides information such as flows in pipes, pressures at junctions, propagation of a contaminant, chlorine concentration, water age, and even alternative ...

  4. Supply and demand - Wikipedia

    en.wikipedia.org/wiki/Supply_and_demand

    Supply chain as connected supply and demand curves. In microeconomics, supply and demand is an economic model of price determination in a market.It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied ...

  5. Price elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Price_elasticity_of_demand

    Depending on its elasticity, a good is said to have elastic demand (> 1), inelastic demand (< 1), or unitary elastic demand (= 1). If demand is elastic, the quantity demanded is very sensitive to price, e.g. when a 1% rise in price generates a 10% decrease in quantity. If demand is inelastic, the good's demand is relatively insensitive to price ...

  6. Base stock model - Wikipedia

    en.wikipedia.org/wiki/Base_Stock_Model

    The base stock model is a statistical model in inventory theory. [1] In this model inventory is refilled one unit at a time and demand is random . If there is only one replenishment, then the problem can be solved with the newsvendor model .

  7. Key–value database - Wikipedia

    en.wikipedia.org/wiki/Key–value_database

    A tabular data card proposed for Babbage's Analytical Engine showing a key–value pair, in this instance a number and its base-ten logarithm. A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table.

  8. Load-following power plant - Wikipedia

    en.wikipedia.org/wiki/Load-following_power_plant

    A load-following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day. [1] Load-following plants are typically in between base load and peaking power plants in efficiency, speed of start-up and shut-down, construction cost ...

  9. Pipe network analysis - Wikipedia

    en.wikipedia.org/wiki/Pipe_network_analysis

    This can be used to calculate mean values (expectations) of the flow rates, head losses or any other variables of interest in the pipe network. This analysis has been extended using a reduced-parameter entropic formulation, which ensures consistency of the analysis regardless of the graphical representation of the network. [3]
