Research on Cold Chain Logistics Transportation Scheme under Complex Conditional Constraints

A mathematical model is proposed to minimize the sum of vehicle fixed cost, fuel carbon-emission cooling time-penalty cost and split-compensation on basis considering three-level cold-chain-logistics network manufacturer, distribution center, seller. The constructed based constraints customer time window, load, demand-splitable, semi-open driving multiple centers. We divide areas according geographical locations carry out transportation processes in stages. target solution, which includes routing, service type, cargo details, etc., has been formulated. two-stage hybrid-heuristic-path-scheme solution algorithm that combines a taboo table, genetic algorithm, an optimal-path-generation load-capacity-constraint time-window-constraint designed view complexity uniqueness scheme. This paper aims reasonably plan resource allocation cold chain logistics enterprises, reduce comprehensive transportation, improve satisfaction, respond green policy advocated by state reducing transit consumption, promote energy conservation emission reduction.
