Abstract
With the optimal operating cost and optimal carbon emission target of the chemical logistics companies, a low-carbon routing optimisation with a multi-energy type vehicle combined problem is proposed by considering the concept of the logistics companies’ low-carbon behaviour. An integrated decision-making of multi-energy type vehicles combined strategy and route optimisation based on customer demand is presented, and an improved genetic algorithm is designed. A case study is then applied based on the data collected from the case research. The effectiveness of the improved genetic algorithm is tested. The two joint objectives of operating cost and carbon emission are examined through the cost analysis of environmental energy vehicles and traditional energy vehicles in different combination scenarios. The case analysis shows that a rational multi-energy type vehicle combination with route optimisation has a significant correlation with the operating cost and carbon emissions, while the environmental vehicle purchasing cost reduction and subsidy policy affect the operating cost.
Highlights
From the perspective of lean logistics management, the transportation equipment system is planned to achieve cost reduction and increased efficiency, energy savings and emission r eduction1
The results show that if a company purchases environmental vehicles based on optimal operating costs, the goal of reducing carbon emissions can be achieved
In the proactive lowcarbon behaviour of a chemical logistics company, based on the customer demand, we comprehensively consider the mechanism of multi-energy type vehicles (MTV) combined transport and route optimisation on the company operating cost and carbon emissions
Summary
From the perspective of lean logistics management, the transportation equipment system is planned to achieve cost reduction and increased efficiency, energy savings and emission r eduction. The means of transportation equipment mentioned in this paper is a drop trailer vehicle. This paper discusses the impact of chemical logistics companies’ operating costs and carbon emission factors on transportation equipment resource allocation decision-making. Transportation equipment is an indispensable part of operating resources. Carbon emissions mainly come from the exhaust emissions generated by traditional energy transportation equipment during the transportation p rocess. Chemical logistics companies should pay attention to environmentally friendly transportation equipment. A reasonable environmental transportation equipment purchase plan formed a multi-energy type of transportation fleet, which has become an essential part of the rational allocation of resources to achieve lean logistics management
