Abstract
To achieve sustainable development, logistics enterprises need not only to reduce costs, but also to save energy for environmental protection and improve customer service level. The improvement of reverse logistics management level of waste tires is of great significance to improve the efficiency of the automobile industry. In this paper, multi-objective programming is adopted to establish the waste tire recycling network model. The decision variable is whether the network nodes are set or not, the traffic flow between nodes. Constraints include meeting customer demand, balance of flow in and out of logistics nodes, etc. The model is solved by ε- constraint. Taking the actual data of the enterprise as an example, the operation results show that the operation cost, carbon emission and customer transportation distance can get an consistence within a certain range. Waste tire logistics enterprises can realize the simultaneous improvement of profit, environmental protection and customer service level.
Highlights
With the rapid development of automobile industry, China has become the world's largest automobile production and sales country
Waste tire recycling industry is a branch of reverse logistics industry, and its competition is fierce
If the level of customer service is low, customers will choose to cooperate with other reverse logistics enterprises
Summary
With the rapid development of automobile industry, China has become the world's largest automobile production and sales country. Waste tire recycling industry is a branch of reverse logistics industry, and its competition is fierce. Waste tire recycling enterprises need to pay attention to the short-term benefits including operating costs and carbon emissions, and the long-term benefits including customer service level. The research on waste tire recycling network and reverse logistics network is mainly from the perspective of logistics enterprises, with the short-term benefit maximization as the objective function. There are few literature on the combination of long-term strategic objectives and short-term profits. The waste tire industry is highly competitive. It is necessary to combine the long-term interests and short-term interests of enterprises for research. On the premise of combining the short-term profits (operating costs and carbon emissions) and long-term. Benefits (service convenience through transportation distance) of the old tire recycling enterprises, the recycling network model is designed and the material dispatching plan is formulated
