Two-Stage Humanitarian Logistics Deprivation Model for the Planning of Scarce KN-95 Facemask Supplies under Agent’s Cooperation

Table 1

Comparative table between the contribution made against different models developed.

Model to compare	Type of programming model	Stage within the humanitarian logistics cycle	Savings in cooperation	Competitive advantages
Franco et al. [10]	Tactical	Response	The cost savings in transportation can be based on productivity—saving time—and competitive costs of vehicle fleets.	It is assumed that each supplier has strength, with is given as follows: a; Supplier A: lower production costs.; b; Supplier B: larger capacities.; c; Supplier C: lower transportation cost.
Pérez-Rodríguez [26]	Operational	Preparation/response	Not captured, it focuses on last-mile distribution based on the fact that they already have inventories available.	There are no competitive advantages.
Cotes and Cantillo [27]	Operational	Response	Not captured, the model developed mentions cooperation but does not express it in the form of coalitions.	There are no competitive advantages.
Our contribution	Operational	Response	The savings in transportation costs come from economies of scale (quantity discount) and the valuation of time is subject to priorities.	There are no predefined competitive advantages for the participants, so we leave the value of the contribution in the coalitions to free will so as not to rule out the existence of a subadditive game.
