The growing importance of the online channel and the increased deployment of new technologies such as smart mobile devices and social networks create new opportunities and challenges for traditional retailers. The retailing industry is moving to a new phase, in which the distinctions between traditional and online channels disappear, namely omni-channel (OC) retailing. The new challenge is to understand...
A new supply chain model which integrates Vendor-managed inventory (VMI) and Third-party logistics (TPL) is discussed. Decentralized coordinating VMI&TPL supply chain model is built firstly. Based on the network which consists of “many vendors, one TPL and one manufacturer”, distribution logistics problem model of decentralized coordinating integrating supply chain of VMI and TPL is built. A simulated...
Inventory-transportation integrated optimization in the distribution system is important research subject of logistics integration strategy. This paper analyses the relationship between inventory and transportation, builds the ITIO issue optimization based on milk-run mode, and combining the character of Model, this paper designs Genetic Algorithm of natural number coding to solve Vehicle Scheduling...
This research involves a study of the existing carsharing services in Singapore. In this paper, a novel method to forecast and relocate vehicle resources for carsharing services was proposed. The idea is adapted from a model of logistical inventory management. The proposed model consists of three main components, i.e., focus forecasting, inventory replenishing, and microscopic traffic simulation....
The objective of the study is to minimize the whole cost of logistic system in view of the long-term planning level. Based on traditional EOQ model, a non-instantaneous replenishment inventory decision model is presented in consideration of transportation cost and the permitted working duration of the vehicles per unit time. The optimal ordering quantity is obtained by the ideas of getting the minimum...
VMI (vendor managed inventory) policy coordinates effectively the antinomy between the inventory and the transportation within logistics distribution system. Under VMI mode, integrating inventory and transportation of the supplier and the demander as a whole is considered to achieve the optimization of total distribution cost. In view of typical one-warehouse multiretailer distribution network in...
The RFID and positioning system technologies are the key enablers for logistics supply chain visibility and tracking. While RFID is useful for inventory and material handling processes in warehouses, as soon as the RFID-tagged goods leave the warehouses, one often lose track of them until the next loading docks. In-between the sending and receiving points, there is often no tracking of the cargo which...
In the previous work, we developed a model for inventory routing problem with split delivery and proposed a hybrid approach based on Lagrangian relaxation to solve the model. Numerical experiments show that the proposed hybrid approach can find a high quality near-optimal solution for the problems with up to 200 customers in a reasonable computation time. In this paper, we further improve and simplify...
Most literatures of Inventory-Routing problems find the solutions by simulation, but few solve the real case problem of logistics companies. This research will apply some specific real logistics company's operating data to study the Inventory-Routing problem. This study first develops a mathematical model for this Inventory-Routing problem, next applies Savings method, 2-opt heuristic method and 1-1...
This paper based on the manipulation of full vehicle logistic network and integrated inventory, in order to optimize automobile logistics network and reduce costs, the integrated optimization model was presented, which provided an integrated view of transportation economies-of-scale, inventory and facility costs as well as service quality, and at the same time a complicated multi-customer network...
This paper considers the infinite horizon inventory routing problem for one-warehouse multi-retailer distribution systems. We focus on developing an analytic approach for evaluating the effectiveness of direct shipping strategy where each vehicle serves only one retailer in one delivery at its optimal replenishment rate. Explicit formula is obtained in terms of a few of easily measurable parameters...
This paper addresses inventory routing problem (IRP) in the context of integrating vendor managed inventory and third party logistics. The IRP model discussed in this paper has three main characters: based on strategy, three-tiered supply chain and many-TPL-one network. This paper describes the problem and assumptions in detail and builds a model and computation procedure for the IRP. A heuristic...
The reuse of end-of-use products is always an important issue. To optimize the closed-loop logistics system for reusing end-of-use products, an integrated optimization model for stochastic dynamic location-routing-inventory problem is presented in this paper. A two-phase heuristic algorithm is also proposed to solve the model. And the validity of the model and algorithm is demonstrated by an example.
In this paper, we propose the active monitoring model for the workflow of RFID logistics management system, and besides the function of taking materials in and out, technology to handle each step for efficient logistics management is applied.For the inventory inspection, users take goods in and out in real time by attaching tags on each item and inspects the stored inventory rapidly with stock inspector...
Logistic distribution is an operation linking with consumer directly ,and takes account for considerable proportion in variable costs in logistics. A scientific and reasonable method to vehicle scheduling is an important operation in logistic distribution. This paper attempts to take VSP in VMI as the tow core problems for further research. VSP in VMI may be looked as the stretch of the VSP above...
