The Web

Consider a web service with different quality of service levels where users may purchase their required web service through a reservation system. The service provider adjusts prices of web service classes over a prespecified time horizon to manage demand and maximize profit. Users may cancel their services as long as they pay a penalty. One of the important challenges for service providers is capacity limitation of the resources employed in offering the web service. Thus, taking this important proposition into account makes pricing strategies considered by the provider has more credit. Another important factor in determining pricing strategies discussed in the present paper is the market influence which can increase or decrease the price that the provider offers. This paper develops a continuous time optimal control model for identifying pricing strategies for the web service classes. We study the optimality condition of the considered model based on maximum principal and propose an algorithm to obtain the optimal pricing policy. Moreover, we perform numerical analyses to evaluate the effect of some parameters on control and state variables and objective function. In addition, we compare the proposed algorithm with genetic algorithm (GA) and simulated annealing (SA) available in Matlab.

Perishable Goods

The problem of pricing distribution services is challenging due to the loss in value of product during its distribution process. Four logistics service pricing strategies are constructed in this study, including fixed pricing model, fixed pricing model with time constraints, dynamic pricing model, and dynamic pricing model with time constraints in combination with factors, such as the distribution time, customer satisfaction, optimal pricing, etc. By analyzing the relationship between optimal pricing and key parameters (such as the value of the decay index, the satisfaction of consumers, dispatch time, and the storage cost of the commodity), it is found that the larger the value of the attenuation coefficient, the easier the perishable goods become spoilage, which leads to lower distribution prices and impacts consumer satisfaction. Moreover, the analysis of the average profit of the logistics service providers in these four pricing models shows that the average profit in the dynamic pricing model with time constraints is better. Finally, a numerical experiment is given to support the findings.

Production Inventory System

We study the effects of different pricing strategies available to a production–inventory system with capacitated supply, which operates in a fluctuating demand environment. The demand depends on the environment and on the offered price. For such systems, three plausible pricing strategies are investigated: static pricing, for which only one price is used at all times, environment-dependent pricing, for which price changes with the environment, and dynamic pricing, for which price depends on both the current environment and the stock level. The objective is to find an optimal replenishment and pricing policy under each of these strategies. This article presents some structural properties of optimal replenishment policies and a numerical study that compares the performances of these three pricing strategies.

Pricing Schemes

The market of Internet service providers (ISPs) is highly competitive. Although many different pricing schemes could be deployed in this market, two types are mainly offered: flat rate pricing and per-minute pricing. These pricing schemes are criticised for limiting ISPs’ revenues and for not addressing customer’s requirements on service quality. We focus on the ISPs’ business relationships and on their pricing strategies in order to analyse revenue sharing mechanisms. We argue that the introduction of incentive pricing schemes, such as dynamic pricing, may enable provision of service quality by improving revenue sharing among ISPs.

Purpose The success of web services involved the adoption of this technology by different service providers through the web, which increased the number of web services, as a result making their discovery a tedious task. The UDDI standard has been proposed for web service publication and discovery. However, it lacks sufficient semantic description in the content of web services, which makes it difficult to find and compose suitable web services during the analysis, search, and matching processes. In addition, few works on semantic web services discovery take into account the user’s profile. The purpose of this paper is to optimize the web services discovery by reducing the search space and increasing the number of relevant services. Design/methodology/approach The authors propose a new approach for the semantic web services discovery based on the mobile agent, user profile and metadata catalog. In the approach, each user can be described by a profile which is represented in two dimensions: personal dimension and preferences dimension. The description of web service is based on two levels: metadata catalog and WSDL. Findings First, the semantic web services discovery reduces the number of relevant services through the application of matching algorithm “semantic match”. The result of this first matching restricts the search space at the level of UDDI registry, which allows the users to have good results for the “functional match”. Second, the use of mobile agents as a communication entity reduces the traffic on the network and the quantity of exchanged information. Finally, the integration of user profile in the service discovery process facilitates the expression of the user needs and makes intelligible the selected service. Originality/value To the best knowledge of the authors, this is the first attempt at implementing the mobile agent technology with the semantic web service technology.

In SOA framework, Portal applications aggregate and render information from multiple sources in easily consumable format to the end users. Web services seem to dominate the integration efforts in SOA. Traditional data-oriented web services require portlet applications to provide specific presentation logic and the communication interface for each web service. This approach is not well suited to dynamic SOA based integration of business processes and content. WSRP 2.0 aim at solving the problem and providing the framework for easy aggregation of presentation services. Is not practical to publish portlets locally if the organisation wishes to publish their portlets as web services to allow their business partners using these services in their portals. UDDI extension for WSRP enables the discovery and access to user facing web services while eliminating the need to design local user facing portlets. Most importantly, the remote portlets can be updated by the web service providers from their own servers.

In most cases, portlets are built to be deployed by local portals. This is not practical if the organisation wishes to publish their Web services and expects other business partners to use these services in their portals. UDDI extension for WSRP enables the discovery and access to user facing Web services provided by business partners while eliminating the need to design local user facing portlets. Most importantly, the remote portlets can be updated by the Web service providers from their own servers. Remote portlet consumers are not required to make any changes in their portals to accommodate updated remote portlets. This results in easier team development, upgrades, administration, low cost development, and usage of shared resources. In this chapter, we deal with the technical underpinning of the UDDI extensions for WSRP (user facing remote Web services) and their role in service sharing among business partners. We outline the WSDL extensions relevant to the remote portlets and WSRP (WSRP specification version 1, 2003). publishing and binding process in UDDI.

Problem faced by goods delivery service providers today is that there are found consumers they have difficulty in finding couriers to transport large goods, thus causing consumers to have to go to the owner of a pickup car or delivery service provider, it can take a lot of time and cost. To solve the problem, there is currently no system that facilitates consumers in ordering couriers optimally. Therefore, it requires a delivery system that can order couriers only through a smartphone owned. The result that was wanted to be achieved in this study was the creation of a multiplatform based courier ordering system with a REST web service architecture that can be accessed through computer and Android platforms. With the construction of this system testing of the web service, the test results of the web service function stated that, all functions tested show valid results, this means that the entire web service function on the application, already fulfilled the design, in addition to testing against the web service, conducted also the black box trial, based on the black box test results, it is concluded that the application created, already according to the design, is proven by all the parts tested showing valid status
