Table 4 Description of various parameters and variables

From: Resource integration optimization of convenience service platforms adopting dynamic service modes in new retail

Notation Description
M Number of service items carried by convenience store
m Index of each service item
Amn Index of different service modes of each service item provided by convenience store
Im For service item m, the total number of individual resources selectable for convenience store’s resource integration
rmi Index of each selectable individual resource
fmn The number f evaluation index utilized by customers to evaluate suppliers’ service level under the service mode Amn
wfmn The degree of concern customers attached to the index fmn
Er(mn)i Customer’s perceived value of service level of supplier rmi under the service mode Amn
umn The ratio of service mode Amn adopted by convenience service platforms under dynamic service modes
Ermi The overall customers’ perceived value of service level of supplier rmi under dynamic service modes
Srmni Satisfaction of collaborative resource rmi toward the service mode Amn
Srmi The overall satisfaction of collaborative resource rmi toward dynamic service modes
Km For service item m, the number of dominant factors of convenience service platforms’ resource integration under dynamic service modes
km For service item m, the index of dominant factors of convenience service platforms’ resource integration under dynamic service modes
Tm For service item m, the expected input time during individual resource integration
Tsta(mi) Starting time to integrate resource rmi
Tend(mi) Finishing time to integrate resource rmi
Ta(mi) The actual time used to integrate resource rmi, Ta(mi) = Tend(mi) − Tsta(mi)
Ts(m) Tolerable time discrepancy during individual resource integration
Ckmi The cost input to improve the dominant factor km during the integration of resource rmi
Lkmi The operation level of the dominant factor km before the integration of resource rmi
Xkmi The improvement amount of the dominant factor km brought by the unit cost input during the integration of resource rmi
Lkmi The operation level of the dominant factor km after the integration of resource rmi
Cmi The overall cost input for the integration of resource rmi under dynamic service modes
Cmax The maximum integration cost allowed by convenience service platform to spend on individual resource integration
g(rmi) A decision variable; g(rmi) = 1 if resource rmi is chosen as a integration object, otherwise, g(rmi) = 0
