To meet the expectation of multi-modal distributions from customers for last-mile delivery, a sustainable two-echelon E-Grocery delivery system The mediatory role of challenge and threat in the relationship between positive thinking skills and perception of excellent performance: a study on football players is studied, which is motivated by the adaption of autonomous delivery robot (ADRs), parcel lockers in E-Grocery distribution industry.We formulate the multi-modal last mile system as a two-echelon location-routing problem with mixed vehicles and mixed satellites11 Intermediate depot.(2E-LRP-MVMS).A multi-objective optimization model is developed to capture the characteristics of cost components and environmental impact.The goal of the 2E-LRP-MVMS is to determine the location facilities, to optimize the number of parcels delivered to two echelons and routes at each level, also to reduce costs caused Immunological basis for enhanced immunity of nanoparticle vaccines by carbon emissions.

A hybrid immune algorithm is proposed, and two improved steps, vaccination and immunization are introduced in the algorithm.This research contributes to the last-mile delivery network design domain by modeling the environmental and economic cost of E-Grocery distribution adopting mixed fleets and mixed satellites.
