Research On The Network Optimization Problem Of Exhibition Logistics System

In the 21st century, exhibition industry developed rapidly in China, has been became a new industry and spur the urban development. China modern exhibition logistics as a strong backing of the exhibition industry, exhibition Logistics exist problem of unbalanced development and has been became a "bottleneck" of exhibition industry gradually. One aspect is that there is a low level of management of the exhibition organization and management personnel, and it is not clear of the management division of the current situation; on the other hand, exhibition logistics service providers in China currently, the exhibition logistics service providers is still purely as a transporter (ETS) role, the exhibition logistics service providers lack capacity to be a professional logistics service providers (ELS). Third-party logistics service providers can provide a more professional exhibition logistics services which under the unified modern exhibition logistics mode. On the standpoint of logistics service providers s, it is a problem that how to decrease in their operations costs mostly and optimize the distribution program, increase revenue under the premise to meet the base of exhibitors and the exhibition organizers. It is the need for third-party logistics service providers pay emphasis on it greatly. The research of exhibition logistics currently, the literature is standing sponsor or exhibitor perspective on how to select logistics service providers conduct evaluation studies partly; the other part of the literature is more development status and mode of operation exhibition logistics; there is few research of exhibition logistics which standing logistics service on the angle of the actual exhibition logistics services to study the optimization. Therefore, it is necessary to have further study of exhibition logistics.This paper analyzes the current situation of the exhibition and research situation of exhibition logistics, and elaborated the concept and characteristics of exhibition logistics, and drawn exhibition logistics mainly has the following characteristics:high value goods transport, transport of goods scattered distribution supply chain is short, the system complexity is high, high degree of information and so on. By then the traditional mode of operation of the exhibition logistics and modern mode of operation of a comparative analysis of the principal mode of operation exhibition logistics, determined by the exhibition organizers unified logistics service providers is the current mode of operation of the main exhibition logistics. By analyzing the distribution process and logistics costs Modem exhibition logistics mode has been the exhibition logistics service optimization problem distribution location problem and route optimization problem. In the perspective of the third-party logistics service providers, first select the model established distribution center, distribution center using genetic algorithm selection, multiple distribution problem into a single distribution center problem, then create a single distribution center VRP model, ant colony optimization algorithm path, get the best logistics solutions.
