| is the decreasing rate of downstream firm sensitivity in the revenue range | is the decreasing rate of downstream firm sensitivity in the loss range | is the downstream firm’s evasion coefficient in case of loss | is the preference degree of downstream firm for product | is the subjective utility of a single product | is the subjective utility of downstream firms’ multiproducts | is the nonnegative distance of each arc | is the storage capacity of the warehouse | is the fixed open cost of warehouse | is the vehicle capacity | is the fixed vehicle scheduling cost | is the load of access node and node | is the risk of order delivery disruption when the manufacturer can provide the product to the downstream firm in the period | is the lower limit of the risk interval value of the delivery disruption of the product order that the downstream firm wants to obtain | is the upper limit of the risk interval value of the delivery disruption of the product order that the downstream firm wants to obtain | means that the downstream firm has a clear demand | is the initial satisfaction of downstream firm to the risk of delivery disruption of the second product order | represents the satisfaction of downstream firm to the risk of delivery disruption of product order in the first cycle | refers to the subjective utility of the downstream firm that obtains product |
