The paper study a three-stage duopoly game model of vertical recycling electronic product differentiation about recycling product quality, recycling technology investment and recycling price competition. The recycling firms' incentives to invest in recycling technologies depend on their relative cost structure. On one hand, we compare in different levels of recycling technology investment the recycling products quality difference firms' investment strategy, on the other hand, we compare the competition degree about different recycling product quality firms in recycling technology investment difference. At last, we regard recycling firms and waste electronic product processing firm as alliance.

Distribution is one of the most important parts of the logistics and Supply Chain, and the performance of a Distribution System will influence the level of logistics directly. However, the evaluation of the performance of a Distribution System was mostly based on qualitative analysis. Analyzing the features of the distribution system, this paper will establish a model of the system based on Stochastic Petri Nets (SPN). By utilizing the mathematical Characteristics of SPN, a method was proposed for quantitatively evaluating the performance of the distribution system. Finally, parameters of the system such as per distribution amount, distribution process weight and the actual loading rate were achieved by a case calculation. © ASCE.

This paper researched the cooperating game in logistics outsourcing under asymmetric information. It set up the cooperative game model in condition of TPL buyer can not observe the TPL logistics operation cost and management cost, and apply maximum principle and principal-agent theory to obtain both the players' cooperative strategies. Finally, assuming the agent is risk-neutral, the authors analyzed the risk cost, incentive cost and total agency cost of TPL buyers. © ASCE.

A Differential Evolution & Genetic Algorithm for Vehicle Routing Problem with Simultaneous Delivery and Pick-up and Time Windows

引用

IFAC Proceedings Volumes 2008年第2期41卷 10576-10581页

作者： Cao Erbao Lai Mingyong Nie Kai College of Economics and Trade Hunan University Changsha410079P.R. China Hunan Province Laboratory of Logistics Information and Simulation Technology Changsha 410079 P.R. China

The vehicle routing problem with simultaneous delivery and pick-up and time windows (VRP-SDPTW) is presented from the point of strategic view that combines the logistics and reverse logistics (bidirectional logistics). A general mixed integer programming mathematic model of VRP-SDPTW is constructed, it can transform into other classical vehicle routing problems by setting different parameters. A hybrid optimization algorithm (HOA) is proposed, which is based principally on the combination of the differential evolution (DE) theory and genetic algorithm (GA). In operation process, we firstly adopted the novel decimal coding to construct the chromosome, and then the differential evolution operator is adopted as the main optimizing scheme, while such techniques of the genetic algorithm, as the novel crossover-operator mutation-operator are designed to improve the result. Therefore it is expected that advantages of both the differential evolution and the genetic algorithm are kept so that the hybrid optimum algorithm can optimize large scale highly nonlinear problems well and improve the efficiency of the optimization process, and can avoid effectively the common defects of early convergence and the diversity of population in traditional genetic algorithm. The computer simulations are used to compare the performance of the proposed method with GA and DE, and numerical results show that the performance of the proposed method is better than the other method.

In researches of many experts and scholars, TSP is widely used in reducing the cost of logistics distribution. However in practice, most ripe models and algorithms can not achieve expected goals, and one important reason is that the models and algorithms do not consider the "Stranger Problem" in logistics distribution. This paper describes the "Stranger Problem", and establishes an improved TSP model based on "Stranger Problem" by defining two parameters named "Strange Degree" and "Strange Coefficient". At last this paper improves C-W algorithms based me improved model, and the computational results are compared with the results based common model. The comparison proves the feasibility and efficiency of the improved model. Copyright ASCE 2007.

The vehicle routing problem with simultaneous delivery and pick-up with time windows (VRP-SDPTW) is a variant of the classical vehicle routing problem (VRP) where clients require simultaneous delivery and pick-up service within the time windows. Deliveries are supplied from a single depot at the beginning of the vehicle's service, while pick-up loads are taken to the same depot at the conclusion of the service. One important characteristic of this problem is that a vehicle's load in any given route is a mix of delivery and pick-up loads, at the same time in any route the vehicle can not violate some constraints, such as: the vehicle capacity time windows and traveling distance constraints. VRP-SDPTW as an extension for vehicle routing problem, which is a complex combinational optimization problem, and is a well know non-polynomial hard (NP-hard) Problem. In this paper, VRP-SDPTW is presented from the point of strategic view that combines the logistics and reverse logistics (bidirectional logistics). We constructed a universal mix integer programming mathematic model of VRP-SDPTW in detail, which can transform into other typical combination optimal problems by setting different parameters. An improved genetic algorithm (IGA) is proposed based on the novel crossover-operator to solve the problem. In operation process, we firstly adopted the novel decimal coding according to a priori sequence among all customers, which consider effectively the vehicle capacity time windows and traveling distance restrictions at the same time. And then a novel crossover-operator is designed. The improved genetic algorithm (IGA) avoids effectively the common defects of early convergence and the diversity of population in traditional genetic algorithm. The experiment result shows that this algorithm can find the optimal or near-optimum solution to VRP-SDPTW effectively. Copyright ASCE 2007.
