平台型開放式企業的形塑過程:i mode 與 blade.org 個案探討 / Formation of the open platform:case studies of i-mode and blade.org

黃繼平, Huang, Ji Ping Unknown Date (has links)
自從二十世紀末以來,管理學者就開始高倡環境不再穩定,企業必須做出相應的改變,才能維持競爭優勢,持續生存下去。為了適應當今的動盪環境,企業發展出網絡式組織的型態,甚至形成跨越組織、互補共存的「平台」與「社群」。同時,企業也發覺自己無法掌握所有的創新靈感、人才、資源,必須跨越組織的疆界,向外尋求協助,進行「開放式創新」。新型態的組織正在成形,尤其發生在高知識密集或者高科技產業中。台灣以高科技產業聞名事業,供應鏈佈局全球,不久的未來(甚至是現在)極有可能產生諸多新型態的組織,因此我們不得不重視這樣的趨勢。 本論文在文獻探討的部分,把焦點放在三大議題上:開放式創新、平台企業、協作社群。吾人試圖尋找這些互異現象的整合架構,從學者的文獻中規納理論架構,找出形塑「開放平台」的重要面向,分別是「核化」與「拔尖」。接著以NTT DoCoMo從1990年代開始發展的i-mode平台,以及IBM在2005年成立的Blade.org社群作為分析個案,用以證實該理論架構的可行性。 最後,本論文歸納出以下結論:首先,企業建構平台時,須運用組織內部資源,但擺脫組織惰性;其次,當企業本身對平台控制程度高時,由企業來形塑平台的使命陳述。企業本身對平台的控制程度低時,平台需要有替代機制,為平台擬定發展方向;第三,發展平台須掌握最小限度的控制,最大程度的發揮;第四,尋求外部連結必須儘量跨越產業,讓平台有更多不同的應用,使平台擴大;第五,平台的形塑過程是個動態過程。 / Management scholars claim the business environment has been dramatically change since the end of 20th century. Enterprises have to respond the transformation of such environment in order to pursue the sustainable advantage and constant deveplopment. To adapt to the dynamic and using knowledge efficiently and effective, enterprise has changed from bureaucracy to networking and cross-boundary organization, which are the so-call platform or community type organization. In the meantime, enterprises gradually find out that they are unable to deal with all the ideas, human resources and corporate assets. Instead, they have to cross the boundary, seek assistance from outside innovators. New type of organization is going to emerge, especially in the knowledge-intensive or high technology industries. Taiwan is world-famous for its development of high technology industry. Also, networking connections among the high-tech companies are widely expanding all over the world. Therefore, it is expectable that the new type of organization will be formed in Taiwan in the near future, and it worthwhile for us to pay attention to the trend. In the content of this paper, the literature review is primarily focused three major issues: open innovation, platform enterprises and collaborative communities. This paper has tried to put the three different kinds of system into an integrated framework, together with inclusion from the scholars' theories, to conclude that an open platform can be formed in two dimensions. These two dimensions are called "coring" and "tipping". To conduct a case study, the research also chose for purpose of analysis and attempted to prove the feasibility of the integrated framework. The cases were obtained from business operational phenomena of companies respectively: i-mode which is owned by NTT DoCoMo, and Blade.org, which is owned by IBM. The research came to the conclusions in five aspects. First, while building the open platform, enterprise should manipulate the resource of the existing business and try to shed the inertia as well as the bureaucracy. Second, a platform leader has to mould the mission statement for the platform controlled by the leader in a great degree. If the platform is not close to the leader, the leader has to create a substitute institution to replace the function of the leader. Third, a manager has to maintain minimum control to facilitate the members of the platform to develop the function and performance heartily by their own. Fourth, a platform leader should try its best to connect with the outside innovation across the industries and develop various applications for easy access. Fifth, formation of the open platform is always a dynamic process.

Diseño de aplicaciones de tiempo real para plataformas abiertas

Barros Bastante, Laura 02 October 2012 (has links)
Se propone una metodología de desarrollo de aplicaciones de tiempo real estricto que van a ser ejecutadas en plataformas distribuidas abiertas. En esta metodología, el diseñador de la aplicación no conoce la carga de trabajo de la plataforma que será ejecutada concurrentemente junto con la aplicación que diseña. La metodología se basa en el paradigma de reserva de recursos, y utiliza como base el concepto de plataforma virtual, tanto para describir el uso de los recursos que una aplicación requiere, como para ejecutar la aplicación satisfaciendo sus requisitos temporales. La plataforma virtual es utilizada en el proceso de negociación con el servicio de reserva de recursos de la plataforma física, con objeto de obtener una configuración de la aplicación que haga compatible su ejecución con la carga de trabajo que ya se está ejecutando en dicha plataforma. La metodología aborda todas las fases del desarrollo de una aplicación: describe la información que debe asociarse al código de la aplicación para poder ser configurado, así como el proceso que permite analizar independientemente su planificabilidad en base a la plataforma virtual; especifica el proceso de despliegue de la aplicación y define la información que se utiliza para negociar su ejecución con el servicio de reserva de recursos de la plataforma física y para generar los datos de configuración que deben ser asignados al código cuando se ejecute. Todos estos procesos son dirigidos por modelos, por lo que la tesis aborda la definición de las transformaciones de modelos requeridas, así como la formulación de los metamodelos formales utilizados en ellas. Por otro lado, aunque la tecnología es independiente de la plataforma de ejecución, se especifica la funcionalidad que debe ofrecer el servicio de reserva de recursos presente en la misma para dar soporte a la metodología propuesta, y se analiza su compatibilidad con algunas implementaciones actualmente disponibles / This thesis proposes a methodology for the development of hard real-time applications that will be executed in open distributed platforms. When this methodology is applied, the application designer does not know the workload of the platform that will execute concurrently with the designed application. The methodology is based on the resource reservation paradigm, and relies on the concept of virtual platform, both to describe the resources usage required by an application to execute, and to run the application guaranteeing the fulfillment of the specified timing requirements. The virtual platform is also used on the negotiation process with the resource reservation service of the physical platform in order to obtain a configuration of the application that supports its execution together with the current workload running on that platform. The methodology deals with all the phases of the application design: it describes the information that must be associated to the application code in order to obtain a proper configuration, as well as the process that allows an independent schedulability analysis of the application based on its virtual platform; it specifies the application deployment process and defines the information that is used to negotiate the execution of the application with the resource reservation service of the physical platform, and to generate the configuration data that must be assigned to the code when it is executed. The methodology follows a model-driven perspective, so the thesis addresses the required models transformations, as well as the formulation of the metamodels used in them. Moreover, although the technology is independent from the execution platform, the functionality that must be provided by the resource reservation service to support the proposed technology is specified and its compatibility with other implementations is analyzed.

Agrothermie - design and testing of a novel hydraulically-actuated, locally vibrating plough

Liu, Jianbin, Beck, Benjamin, Münch, Jakob, Grosa, André, Kahle, Roman, Weber, Jürgen, Herlitzius, Thomas 26 June 2020 (has links)
Economic utilization of geothermal networks under agricultural surfaces needs large agricultural areas. In order to exploit the cultivated land more effectively, this paper proposes a novel locally vibrating plough system that employs a hydraulic actuator direct on the plough blade instead of the state of the art external vibration units. Starting with a description of geothermal networks under agricultural surfaces and the construction technology in details, the contribution shows different concepts, the development and test of the most promising solution for imprinting local vibrations at the cutting edge with the goal of traction force reduction. A virtual demonstrator, the test rig set-up and the control concepts are described. Both of the closed-loop simulation and experimental position control of the entire vibration system demonstrate that the novel design has impressive performance improvement. Finally, the integration of the vibration system into a prototype tool is shown and the reduction of the traction force is proven by experiments carried out with a tractor on a testing field.
