Case Study of Joint Online Truck Scheduling and Inventory Management for Multiple Warehouses

Study about Joint Online Truck Scheduling and Inventory Management for Multiple Warehouses

Abstract: For a real world problem transporting pallets between warehouses in order to guarantee suffcient supply for known and additional stochastic demand we propose a solution approach via convex relaxation of an integer programming formulation, suitable for online optimization. The essential new element linking routing and inventory management is a convex piecewise linear cost function that is based on minimizing the expected number of pallets that still need transportation. For speed, the convex relaxation is solved approximately by a bundle approach yielding an online schedule in 5 to 12 minutes for up to 3 warehouses and 40000 articles; in contrast, computation times of state of the art LP-solvers are prohibitive for online application.

Case Study on Inventory Management

Introduction: Consider the following real world problem. Given several warehouses connected by a shuttle service of several trucks for shipping pallets of stored articles between them; given also an online stream of orders, that are stochastic in nature and that have to be handled within short time at specific warehouses. Is it possible to provide, online, a schedule of truck routes and truck loads so that all products are available at the right place ahead of processing time even if the realization of the schedule is subject to further uncertainties? We suggest a solution approach based on convex relaxation and demonstrate its practical suitability on real world data of our industrial partner eCom Logistik GmbH & Co. KG.  Keep reading…

Case Study on Wireless Communication Methodologies (WAP)

Study about Wireless Communication Methodologies (WAP)

Executive Summary: Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or the entire communication path. In the 21-century, wireless communication and high-speed communication incorporating computation power, mobile network/internet access capability, and consumer electronics, become emerging technologies.

Case Study on Wireless Communication Methodologies

Wireless communications are transmitted through the air via radio waves of various frequencies. Radio frequency radiation (RFR) is one of several types of electromagnetic radiation. Data transmission in a Wireless Communication is done by means of an unguided medium. Antennas are used to transmit the signal. There are different kinds of antennas like Whip, Panel and Dish. Antennas need to be placed at specific heights in relation to one another in order to transmit and receive signals. As a result, height is a determining factor in the design and siting of wireless communications facilities. Keep reading…

Case Study in WAP Development

Study about WAP Development

This paper will relate the experiences of a programming team that, in two months, went from knowing relatively little about WAP to developing a prototype application for an international investment bank. It summarizes the experiences of, and lessons learned by, the team during this  intensive period, emphasizing in particular the differences between delivering applications to mobile devices and desktop PCs. We will focus on what the developers considered when designing and building a prototype application for the  WAP platform.

Case Study on WAP Development

The bank was motivated to develop a WAP prototype for a number of reasons. Firstly, it was important for the IT function within the bank to gain exposure and understanding of the technology (and system integration issues) that would be faced as we move towards a pervasive computing model. Secondly, it was felt that a certain amount of speculative research into mobile technology was important if the bank was to be seen as an innovator in the marketplace.The prototype delivered a WAP front-end to an existing global-chat system. The system allows traders to exchange market information and news on stocks and bank affairs. The application is critical to the bank, in that it facilitates the communication of market-related information between key business users. Keep reading…

A Study report on Designing for Small User Interfaces: WAP

A Study report about Designing for Small User Interfaces: WAP

Introduction: Current and upcoming WAP-capable mobile phones introduce new user interfaces where standard methods for application design often fail. Automated translation of HTML to WML produces screen layouts and input mechanisms that are often not useable on a mobile phone. In this paper we suggest a structured approach for building WAP application and in particular the development of the user interface. First we give a brief summary on the discriminating feature of a phone interface and on mechanisms to build applications on WAP devices. Then we provide guidelines on how to port from Web to WAP and how to develop WAP-Applications. We finally introduce the WAP application that led to our findings.

Case Study on Small User Interfaces

PDA like devices as well as phones offer a number of applications beyond phoning, such as messaging, calculator, address book, and games. For these applications, and to some extent even for phoning, the usage of devices from different manufactures (or even for different models of one manufacturer) does not follow the same rules. With the introduction of the WAP standard a manufacturer independent platform for the development and distribution of applications for WAP-phones and other WAP-devices is given. Applications are written in WML and or in WMLS and constitute of one or more decks consisting of on or more cards. The resource is provided on a server and can be downloaded by the user.

Case Study on Early Adopters of WAP for Hotels: A Series of European

Study about Early Adopters of WAP for Hotels: A Series of European

Background: Today there is hardly a hotel chain, hotel guide or destination marketing organisation which do not have a Web-site. Also most individual hotel-properties have home-pages of their own. Now that the hotel Web-sites are more or less in place, a new channel for Internet access comes along: Mobile Internet access via WAP enabled mobile phones and other wireless devices. Penetration of mobile phones is high already in Europe and is increasing fast. Furthermore, fromnow on, and during the next few years, more and more mobile phones will be of the WAP enabled types. This does not mean that these special mobile phones can access ordinary Web-sites (written in html code), since the screen of a WAP phone is rather small. Current Web-sites will have to be supplemented with special WAP versions of these same sites.

Case Study on WAP for Hotels

The number of mobile phone users have been increasing as is reaching saturation. There is a shift from ordinary mobile phones to WAP enabled phones. Indeed, the majority of new phones sold are WAP-enabled. However, the WAP-function of WAP-enabled phones is not necessarily being used, nd therefore the actual number of WAP-users may not have reached early expectations. This series of case studies takes a content provider’s perspective and reviews the experiences of a number of early adopters of WAP for providing information and in some instances also booking facilities for hotel accommodation. keep reading…

A Case Study in Mobile Entertainment: WAP–G

A Study about Mobile Entertainment: WAP–G

Abstract: In this case study report, we will provide a brief outline of the specific requirements for the WAP-G platform and, in the main part of the paper, focus on two technical key issues in the context of interactive multiplayer WAP games: maintaining consistent user session and game state information in presence of unreliable WAP connections and device independent output generation and transformation for not fully standardized WML end user devices. The former issue has been dealt with by running an array of server-side Mealy-style state machines yielding a consistent game state database used for session and game recovery in presence of flapping WAP connections

Case Study on Mobile Entertainment

Although GPRS will improve the situation with respect to bandwidth and network latency significantly, the practical impact on stability and availability is still to be evaluated. For interactive text based services with rather low data transfer volumes, e.g., the interactive games based on the Wireless Application Protocol (WAP) as discussed in this paper, limitations with respect to connection stability and service availability are considered more severe than a lack of bandwidth or guaranteed response time. Additionally, the micro browsers delivered with WAP enabled mobile end user devices (e.g., cell phones) feature a significantly smaller common core functionality than traditional html browsers.

Case Study on Model-Based Testing of a WAP Gateway: Industrial

Study about Model-Based Testing of a WAP Gateway: Industrial

Abstract: We present experiences from a case study where a model-based approach to black-box testing is applied to verify that a Wireless Application Protocol (WAP) gateway conforms to its specification1 . The WAP gateway is developed by Ericsson and used in mobile telephone networks to connect mobile phones with the Internet. We focus on testing the software implementing the session (WSP) and transaction (WTP) layers of the WAP protocol. These layers, and their surrounding environment, are described as a network of timed automata. To model the many sequence numbers (from a large domain) used in the protocol, we introduce an abstraction technique. We believe the suggested abstraction technique will prove useful to model and analyse other similar protocols with sequence numbers, in particular in the context of model-based testing.

Case Study on WAP Gateway

Introduction: Testing is the dominating technique used in industry to validate that developed software conforms to its specification. To improve the efficiency of testing, model-based testing has been suggested as an approach to automate the generation of the tests to be performed during testing. In model-based testing, a model is used to specify the desired behavior of the developed software, and the testing efforts aims at finding discrepancies between the behavior of an implementation and that specified by the model. This process can be automated by applying a test generation tool to produce the test to be used during testing, and by automating the execution and validation of the tests using a test-execution tool.
