  2. Unit commitment problem in electrical power production

    en.wikipedia.org/wiki/Unit_Commitment_Problem_in...

    In a free-market regime, the aim is rather to maximize energy production profits, i.e., the difference between revenues (due to selling energy) and costs (due to producing it). If the GenCo is a price maker, i.e., it has sufficient size to influence market prices, it may in principle perform strategic bidding [12] in order to improve its ...

  3. Conditional factor demands - Wikipedia

    en.wikipedia.org/wiki/Conditional_factor_demands

    Isocost v. Isoquant Graph. In the simplest mathematical formulation of this problem, two inputs are used (often labor and capital), and the optimization problem seeks to minimize the total cost (amount spent on factors of production, say labor and physical capital) subject to achieving a given level of output, as illustrated in the graph.

  4. Automatic generation control - Wikipedia

    en.wikipedia.org/wiki/Automatic_generation_control

    In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power grid requires that generation and load closely balance moment by moment, frequent adjustments to the output of generators are necessary.

  5. Economic lot scheduling problem - Wikipedia

    en.wikipedia.org/wiki/Economic_lot_scheduling...

    The economic lot scheduling problem (ELSP) is a problem in operations management and inventory theory that has been studied by many researchers for more than 50 years. The term was first used in 1958 by professor Jack D. Rogers of Berkeley, [1] who extended the economic order quantity model to the case where there are several products to be produced on the same machine, so that one must decide ...

  6. Total factor productivity - Wikipedia

    en.wikipedia.org/wiki/Total_factor_productivity

    The equation below (in Cobb–Douglas form) is often used to represent total output (Y) as a function of total-factor productivity (A), capital input (K), labour input (L), and the two inputs' respective shares of output (α and β are the share of contribution for K and L respectively).

  7. Project management triangle - Wikipedia

    en.wikipedia.org/wiki/Project_management_triangle

    Cost Estimating is an approximation of the cost of all resources needed to complete activities. Cost budgeting aggregating the estimated costs of resources, work packages and activities to establish a cost baseline. Cost Control – factors that create cost fluctuation and variance can be influenced and controlled using various cost management ...

  8. Newsvendor model - Wikipedia

    en.wikipedia.org/wiki/Newsvendor_model

    – fixed cost. This cost always exists when the production of a series is started. [$/production] – variable cost. This cost type expresses the production cost of one product. [$/product] – the product quantity in the inventory. The decision of the inventory control policy concerns the product quantity in the inventory after the product ...

  9. Linear–quadratic regulator - Wikipedia

    en.wikipedia.org/wiki/Linear–quadratic_regulator

    The magnitude of the control action itself may also be included in the cost function. The LQR algorithm reduces the amount of work done by the control systems engineer to optimize the controller. However, the engineer still needs to specify the cost function parameters, and compare the results with the specified design goals.
