ABSTRACT

Companies’ software ecosystems comprise applications that support their business processes. Frequently, these applications have been developed with different technologies and with no concern about integration. Integration platforms are tools that facilitate the development and execution of integration solutions. In this article, we propose a methodology to support software engineers in the decision-making process for an integration platform when performance is a central requirement. The proposed methodology adds objective criteria for performance assessment purposes and has been used to rank the five most popular integration platforms in order to prove its feasibility.  相似文献

The Resource-Based View of Competitive Advantage in Two-Sided Markets   总被引:1,自引:0,他引:1  
abstract    Using two-sided markets as a specific market context, we show that cross-group network effects can turn the participants of a two-sided network into critical resources. In two-sided markets such as payment cards and personal computer operating systems, two groups of agents interact with each other via a common network platform; the value of joining the network for agents in one group depends on the number of participants in the other group. In these markets, resource heterogeneity is represented by different sizes of existing networks; resource accumulation possesses all five characteristics of asset-stock accumulation summarized by Dierickx and Cool. The unique resource accumulation process provides an isolating mechanism for large networks to sustain their resource and competitive advantages. Using two dynamic systems models, we show that resource heterogeneity (i.e. varying initial network sizes) is a source of sustained competitive advantage for two-sided networks and has significant impact on long-term competition dynamics. The findings illustrate the importance of incorporating market context in the research of the resource-based view of competitive advantage.  相似文献

As more and more wireless sensor nodes and networks are employed to acquire and transmit the state information of power equipment in smart grid, we are in urgent need of some viable security solutions to ensure secure smart grid communications. Conventional information security solutions, such as encryption/decryption, digital signature and so forth, are not applicable to wireless sensor networks in smart grid any longer, where bulk messages need to be exchanged continuously. The reason is that these cryptographic solutions will account for a large portion of the extremely limited resources on sensor nodes. In this article, a security solution based on digital watermarking is adopted to achieve the secure communications for wireless sensor networks in smart grid by data and entity authentications at a low cost of operation. Our solution consists of a secure framework of digital watermarking, and two digital watermarking algorithms based on alternating electric current and time window, respectively. Both watermarking algorithms are composed of watermark generation, embedding and detection. The simulation experiments are provided to verify the correctness and practicability of our watermarking algorithms. Additionally, a new cloud-based architecture for the information integration of smart grid is proposed on the basis of our security solutions.  相似文献

This study proposes a multi-agent-based model for bilateral multi-objective negotiation in electronic commerce trading. The function and behaviour of several types of agents are discussed. These agents interact with each other in our negotiation support system model to create the most appropriate solution for both negotiating parties. In particular, we are concerned with a win-win negotiation approach in which agents seek to strike a fair deal that also maximizes the payoff for everyone involved. That is, if the opponent cannot accept an offer then the proponent should endeavour to find an alternative to make a trade-off. Against this background, a utility model based on fuzzy constraint satisfaction problems is proposed to ensure that these agents reach a solution that is fair for both negotiating parties if such a solution exists. The model uses prioritized fuzzy constraints to indicate how concessions should be made when necessary. In addition, by incorporating the notion of a negotiation argument into our evaluation model, the agents can sometimes reach agreements that would otherwise be impossible. Finally, a numerical example is given to display the applicability of the proposed approach for electronic trading assistance.  相似文献

Industrial network flow involves three domains: infrastructure, individual subjects of movement, and planning and control of the movement. Examples include supply chain and intelligent transportation. These traditionally isolated domains can be digitally connected to enhance their performance. Digitization of the infrastructure provides real-time data to facilitate its operation, while digitally connecting the subjects to the infrastructure allows for tailored services and support to particular subjects. Connection of both to the enterprise information systems enables adaptive control for the application (e.g. logistics) at a global optimization level. Previous results in the field cover separate aspects of planning/routing, real-time monitoring, and trip support. Toward this end, a new highway-based subject-infrastructure-enterprise (SIE) information integration model using digital connection is proposed to the field of industrial network flow control for application to intelligent transportation and supply chain management. The SIE model supports industrial network flow control in a way comparable to an adaptive control panel administering an automated material handling system. In this metaphor, the global infrastructure becomes ‘controllable’ similar to factory conveyors and automated guided vehicles. This paper presents a conceptual design substantiated with information requirements analysis. An empirical experiment at locations in New York State shows the technical feasibility of the digital connection envisioned.  相似文献

Our opinions and ideas are shaped by what our friends said and what we read or watched on mass media. In this paper, we propose a concise and analyzable model to study the effects of mass media modeled as an applied external field, and social networks on public opinions based on the multi-state voter model, and a tuned parameter can control the relative intensity of the effects of mass media and social networks. We consider a generalized scenario where there exist committed or stubborn agents in the networks whose opinions are not affected by their friends or mass media. We find that the fraction of each opinion will converge to a value which only relates to the fractions and degrees of stubborn agents, and the relative intensity between media and network effects. The final agents with media opinion, except the stubborn agents, also include the increment produced by the internal impact of social networks and that caused by the external impact of media. Interestingly the second increment is composed of two parts, one is from the media effect when there are no interactions between agents and the other is from the influence of media on agent opinions caused by social network structure. That is the interactions among agents within social networks can amplify media influence. Finally we also discuss several extensions to the dynamics model which consider more realistic scenarios.  相似文献
