The number f evaluation index utilized by customers to evaluate suppliers’ service level under the service mode A_mn

w_fmn

The degree of concern customers attached to the index f_mn

E_r(mn)i

Customer’s perceived value of service level of supplier r_mi under the service mode A_mn

u_mn

The ratio of service mode A_mn adopted by convenience service platforms under dynamic service modes

K_m

For service item m, the number of dominant factors of convenience service platforms’ resource integration under dynamic service modes

k_m

For service item m, the index of dominant factors of convenience service platforms’ resource integration under dynamic service modes

T_m

For service item m, the expected input time during individual resource integration

T_sta(mi)

Starting time to integrate resource r_mi

T_end(mi)

Finishing time to integrate resource r_mi

T_a(mi)

The actual time used to integrate resource r_mi, T_a(mi) = T_end(mi) − T_sta(mi)

T_s(m)

Tolerable time discrepancy during individual resource integration

C_kmi

The cost input to improve the dominant factor k_m during the integration of resource r_mi

L_kmi

The operation level of the dominant factor k_m before the integration of resource r_mi

X_kmi

The improvement amount of the dominant factor k_m brought by the unit cost input during the integration of resource r_mi

L^∗_kmi

The operation level of the dominant factor k_m after the integration of resource r_mi

C_mi

C_max

The maximum integration cost allowed by convenience service platform to spend on individual resource integration

g(r_mi)

A decision variable; g(r_mi) = 1 if resource r_mi is chosen as a integration object, otherwise, g(r_mi) = 0
