The Research On The Random Requirement Of Inventory And Transportation Integrated Optimization Problem

With international competition in the market continues to accelerate,enterprises are facing the survival and development of a more complex question.In order to gain a competitive advantage,many national governments,research institutions,enterprises have turned their attention to the "logistics management," "supply chain design," pay more attention to the "third profit source," to explore and use.More emphasis on modern logistics management system in the logistics chain and logistics coordination improved overall system performance,but existing domestic logistics and more focused on the macro logistics,even for micro-logistics study is only to focus only on certain areas of one aspect.Therefore,this paper will be sold in two logistics system an important part of that inventory control and optimization of transport route to a big problem,the joint search of a problem rather than an optimal solution.More emphasis on modern logistics management system in the logistics chain coordination and logistics overall system performance improvement,but the domestic research on the existing macro focus on the logistics,even for micro-logistics study,just only concentrate on a specific field of of a particular aspect.This paper will be the most important logistics system two areas,namely,inventory control and transportation organizations integration into a big problem,to seek the joint rather than one of the optimal solution.Although these two issues as a theoretical studies has been:relatively mature,but as the transport optimization and inventory management that has existed between the "back-effectiveness" of their synthesis is a big problem,in theory,how Mathematical analysis and how to use the language features described there is much work to be further studied,and how to ensure that theoretical research results more easily applied to the actual logistics management is of great significance and it is necessary to discuss the issue.From the point of departure for the study,use of analysis methods.In this paper,systematic,integrated perspective,the two inventories in the supply chain costs and transportation costs for research.First of all,on the theoretical basis of this paper,summing up foreign and domestic stocks and transport problems of the status quo,a similar study by the multi-storey cement products-sales logistics supply chain complex issue of a simplified model:warehousing and transportation joint optimization model.Secondly,the model is a heuristic algorithm to solve-genetic algorithm,in some assumptions on the basis of the model to find the optimal solution. Of the genetic algorithm is simple,as well as a key step in genetic algorithm to a simple statement,and the model was solved.Again this specific combination of strength,and the establishment of the model solution,and optimize and compare the costs before,in order to explore the model in the application of practical problems.Finally,the storage and transport of joint optimization problems are put forward.
