Abstract: With the increasing number of vehicles in the city, the impact of vehicle exhaust on the environment is more and more great, and enterprises have higher and higher requirements on time. However, the traditional study of LIRP seldom considers the factors of energy saving and emission reduction. Aiming at the integrated optimization research of enterprise logistics, based on the traditional LIRP, the two factors of carbon emission cost and time window penalty cost are comprehensively considered to solve the problem of urban vehicle distribution. The location, inventory and path problems are studied in an integrated way, establishing a LIRP model with the objective of minimizing the economic cost, and solving the problem with the improved differential evolution algorithm. Through an analysis of different scale examples, the accuracy of the model and the effectiveness of the differential evolution algorithm designed are verified, which can save the cost of enterprise distribution and provide a certain reference value.

Key words: location-inventory-routing problem (LIRP), time windows, carbon emissions, differential evolution algorithm
