  2. Economic order quantity - Wikipedia

    en.wikipedia.org/wiki/Economic_order_quantity

    The single-item EOQ formula finds the minimum point of the following cost function: Total Cost = purchase cost or production cost + ordering cost + holding cost Where: Purchase cost: This is the variable cost of goods: purchase unit price × annual demand quantity. This is .

  3. Total cost - Wikipedia

    en.wikipedia.org/wiki/Total_cost

    The additional total cost of one additional unit of production is called marginal cost. The marginal cost can also be calculated by finding the derivative of total cost or variable cost. Either of these derivatives work because the total cost includes variable cost and fixed cost, but fixed cost is a constant with a derivative of 0. The total ...

  4. (Q,r) model - Wikipedia

    en.wikipedia.org/wiki/(Q,r)_model

    The annual stockout cost is proportional to D[1 - S(Q,r)], with the fill rate beying: ... Total cost function and optimal reorder point. The total cost is given by ...

  5. Economic production quantity - Wikipedia

    en.wikipedia.org/wiki/Economic_production_quantity

    Inversely, the total holding cost increases as the production quantity increases. Therefore, in order to get the optimal production quantity we need to set holding cost per year equal to ordering cost per year and solve for quantity (Q), which is the EPQ formula mentioned below.

  6. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...

  7. Average cost - Wikipedia

    en.wikipedia.org/wiki/Average_cost

    In economics, average cost (AC) or unit cost is equal to total cost (TC) divided by the number of units of a good produced (the output Q): A C = T C Q . {\displaystyle AC={\frac {TC}{Q}}.} Average cost is an important factor in determining how businesses will choose to price their products.

  8. Economic cost - Wikipedia

    en.wikipedia.org/wiki/Economic_cost

    Total variable cost (TVC) is the same as variable costs. [5] Fixed cost (TFC) are the costs of the fixed assets those that do not vary with production. [6] Total fixed cost (TFC) Average cost (AC) are total costs divided by output. AC = TFC/q + TVC/q Average fixed cost (AFC) is equal to total fixed cost divided by output i.e. AFC = TFC/q. The ...

  9. Cost function - Wikipedia

    en.wikipedia.org/wiki/Cost_function

    Cost function. In economics, the cost curve, expressing production costs in terms of the amount produced. In mathematical optimization, the loss function, ...
