Abstract

To address the coupled decisions of patient assignment, caregiver assignment, synchronized-service coordination, and cross-center resource sharing in multicenter synchronized home health care scheduling, this study develops a bi-objective optimization model that minimizes synchronization coordination cost and system operating cost, and proposes an Improved Strength Pareto Evolutionary Algorithm 2 (ISPEA2) . The proposed algorithm represents synchronized tasks using real and virtual nodes and integrates matrix encoding, constraint-embedded initialization, route time propagation, limited feasibility repair, state-feedback parameter adjustment, and conditional population invasion to improve search efficiency. Experimental results on 12 extended Solomon instances show that ISPEA2 simultaneously achieves the best Inverted Generational Distance (IGD) and Hypervolume (HV) values on 7 instances. Compared with four mechanism variants, ISPEA2 reduces IGD by 10.07%–22.81% and increases HV by 3.87%–5.31%. The results verify the effectiveness of the proposed model and algorithm, demonstrating that ISPEA2 improves the convergence and coverage of nondominated solution sets under complex constraints.
