After the appropriate quantities have been determined for the various parts involved in pricing, the price of the orders will be determined based on the pricing formula. However, there are situations in which the price of orders may need to increase or decrease. For example, during peak hours you may want prices to rise. Or, on holidays, you want to reduce the price of orders. To cover this pricing model, a feature called distance coefficients is used. These coefficients are multiplied by the price of the orders, thus making the price calculation more flexible.
