Table 2

Variable parameter description of discrete supply networks.

---

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
