This paper presents a mathematical model for two-stage planning of transportation and inventory for many sorts of products (multi-commodity). The situation considered in this paper, which happens in a local furniture manufacturing firm, is that the total supply in origins exceeds the current-stage's total demand from all destinations (markets). Therefore, the problem is how to arrange the current-stage's shipping in consideration of next-stage's (that is, future's) inventory in both origins and destinations. A mathematical model is proposed for the problem with the objective of minimizing the total cost of both shipping and inventory for all products within two stages. Meanwhile, since the next-stage's shipping costs usually are unknown, this paper presents a new concept of rational unit shipping cost: a forecasted average cost with weight of next-stage's shipping amount. Finally, a numerical example extracted from the furniture manufacturing company with 4 origins, 4 destinations and 4 commodities is illustrated in the paper. Significance: This paper presents a mathematical model for multi-commodity, two-stage transportation and inventory problem. The developed model is flexible for adjusting of the next-stage's shipping plan in accordance with the practical conditions at that time. It is also proved that many variables can be reduced by use of the rational unit shipping cost.

Open Source Tool for networks Management Communication

Journal of Electrical Engineering 2017年第1期5卷 35-46页

Considering the complexity of the networks and the need for telecommunication operators （Telco） to present innovations to their clients, the quickest possible, one of the solutions for this complexity could be to centralize its configuration. Thus the SDN （software-defmed networking） concept may be an important solution. This paper suggests the implementation of a tool to support the development and testing of networks and services before they are put into production. The use of a tool that simplifies the configuration of a network service makes the networks and services to be less susceptible to errors and failures by those who set them up, thus allowing telecom operators, among others, to be able to create new services, improve the monitorization of their human resources and, above all, improve their fmancial results. In the end, success will be achieved because with a simple interaction and basic knowledge we are able to manage network services.

An Application of a Heuristic network Algorithm to Cable Logging Layout Design

引用

Journal of Forest Engineering 2004年第1期15卷 11-24页

This paper describes a method for optimizing cable logging layouts using a heuristic network algorithm. A timber harvest unit layout is formulated as a network problem. Each grid cell containing timber volume to be harvested is identified as an individual entry node of the network. Mill locations or proposed timber exit locations are identified as destinations. Each origin will then be connected to one of the destinations through alternative links representing alternative cable corridors, harvesting equipment, landing locations, and truck road segments. A heuristic algorithm for network programming is used to solve the cost minimization network problem. A computerized model has been developed to implement the method. Logging feasibility and cost analysis modules are included in the model in order to evaluate the logging feasibility of alternative cable corridors and estimate yarding and transportation costs. The model was successfully applied to a harvest planning area to generate harvesting plans. This case study indicates that the planning method is best used for pre-planning since modeling assumptions with respect to tail spar availability and unconstrained road alignments may require modification of the plan before implementation.

2009年

作者： Marc Mézard Andrea Montanari

ISBN: (数字)9780191547195

ISBN: (纸本)9780198570837

This book presents a unified approach to a rich and rapidly evolving research domain at the interface between statistical physics, theoretical computer science/discrete mathematics, and coding/information theory. It is accessible to graduate students and researchers without a specific training in any of these fields. The selected topics include spin glasses, error correcting codes, satisfiability, and are central to each field. The approach focuses on large random instances and adopts a common probabilistic formulation in terms of graphical models. It presents message passing algorithms like belief propagation and survey propagation, and their use in decoding and constraint satisfaction solving. It also explains analysis techniques like density evolution and the cavity method, and uses them to study phase transitions.

Scheduling for Steel Making Process Using Mathematical programming Method

引用

IFAC Proceedings Volumes 1989年第11期22卷 129-134页

作者： T. Takahashi M. Konishi S. Tamura H. Hanaoka H. Nakagawa Electronics Research Laboratory Kobe Steel Ltd. Kobe Japan Electronics Department Kobe Steel Ltd. Kobe Japan Kobe Works Kobe Steel Ltd. Kobe Japan

A scheduling system for steel making process has been developed, which controls the material flow from a blast furnace to continuous casters. The scheduling method consists of heuristic logic and a mathematical programming algorithm. In the first part of the system, the order of the jobs in each process is decided using a heuristic procedure, and the time schedule of the refining and casting process is calculated using a linear programming method. In the second part, all the restrictions and the requirements in the hot metal processing are formulated in a problem of network programming to search for the optimum flow with minimum cost.

Java and XML Data Binding shows you how to put the new XML data binding APIs to work. XML is an excellent tool for representing data. Ultimately, though, its not enough to represent data; we also need to work with it, and working directly with XML documents is awkward. You have to navigate through the document, working with XML constructs such as elements and attributes. programming at this level is awkward and alien to many software developers.

Foundation website creation with CSS, XHTML, and JavaScript 1

ISBN: (纸本)9781430209928;1430209925

This book covers the entire process of building a website. This process involves much more than just technical knowledge, and this book provides you with all the information you'll need to understand the concepts behind designing and developing for the Web, as well as the best means to deliver professional, best-practice-based results. There is far more to building a successful website than knowing a little Hypertext Markup Language (HTML). The process starts long before any coding takes place, and this book introduces you to the agile development process, explaining why this method makes so much sense for web projects and how best to implement it. Planning is vital, so you'll also learn how to use techniques such as brainstorming, wireframes, mockups, and prototypes to get your project off to the best possible start and help ensure smooth progress as it develops. An understanding of correct, semantic markup is essential to any web professional, so this book explains how XHTML should be used to structure content so that the markup adheres to current web standards. You'll learn about the wide range of HTML elements available to you, and you'll learn how and when to use them through building example web pages. Without creative use of Cascading Style Sheets (CSS), websites would all look largely the same. CSS gives you the ability to set your website apart from the rest while maintaining the integrity of your markup. You'll learn how CSS works and how to apply styles to your pages, enabling you to realize your design ideas in the browser. JavaScript can be used to make your website easier and more interesting to use. This book provides information on appropriate uses of this technology and introduces the concepts of programming using it. You'll also see how JavaScript works as part of the much-hyped technique Ajax and in turn where Ajax fits into the wider Web 2.0 picture. While a website is being built, it needs to be tested across multiple browsers and platforms to e
