To decrease the influence of technical/data interactions on project progresses, the information flow scheduling models based on the extended DSM is presented. Firstly, infor- mation dependencies are divided into four types： series, parallel, coupling and similar. Secondly, different types of dependencies are expressed as DSM units, and the exten- ded DSM model is brought forward, described as a block matrix. Furthermore, the information flow scheduling methods is proposed, which involves four types of opera- tions, where partitioning and clustering algorithm are modified from DSM for ensuring progress of high-priority project, merging and converting is the specific computation of the extended DSM. Finally, the information flow scheduling of two machine tools development is analyzed with example, and different project priorities correspond to different task sequences and total coordination cost. The proposed methodology provides a detailed instruction for information flow scheduling in multi-product development, with specially concerning technical/data interactions.展开更多

Case studies of eleven cities in Zhejiang (Hangzhou, Ningbo, Wenzhou, Jiaxing, Huzhou, Shaoxing, Jinhua, Quzhou, Zhoushan, Taizhou and Lishui) illustrated regional sustainable development approach. In this study, to provide insight into spatial and dynamic analysis of region sustainable development, we calculated the relative carrying capacity of land resources and economical resources and synthetical carrying capacity of resources in different cities in Zhejiang, and geographic information system was carried out. The results showed that all cities but Hangzhou and Ningbo were ecologically sustainable, and relative carrying capacity of land resources in northern and eastern Zhejiang was larger than those in southern and western Zhejiang. The sampling years of Wenzhou, Hangzhou and Ningbo contribution rates of land resource to synthetic carrying capacity were grouped into three stages, and there were two milestones trends and changes in 1996 and 2004, respectively. This study demonstrated that geographic information system and relative carrying capacity of resources are effective for assessment of region sustainable development, and provide policy guidelines for decision-making.展开更多

In other words, the enterprise and general management, but not necessarily be governance. Further extended the policy implication is that： the establishment of the basic corporate governance structure is the form of the restrictions, not all companies need to establish the corporate governance structure. Only with the direction of general enterprise development in line, can really play a role in guiding the enterprise information, so as to further promote the overall development of enterprises as information planning and development needs accuracy only in the establishment of accurate information. Guided by this perspective, this paper proposes the novel enterprise information management paradigm under the background of data and lnternet, the proposed methodology solves the related challenges well.展开更多

However, the developments of Ocean Information Systems(OISs) often suffer from low efficiency because of repetitive work and continuous modifications caused by dynamic requirements. In this paper, the basic requirements of OISs are analyzed first, and then a novel platform DPOI is proposed to improve development efficiency and enhance software quality of OISs by providing off-the-shelf resources. In the platform, the OIS is decomposed hierarchically into a set of modules, which can be reused in different system developments. These modules include the acquisition middleware and data loader that collect data from instruments and files respectively, the database that stores data consistently, the components that support fast application generation, the web services that make the data from distributed sources syntactical by use of predefined schemas and the configuration toolkit that enables software customization. With the assistance of the development platform, the software development needs no programming and the development procedure is thus accelerated greatly. We have applied the development platform in practical developments and evaluated its efficiency in several development practices and different development approaches. The results show that DPOI significantly improves development efficiency and software quality.展开更多

There are some application softwares of soil database to manage such a large amount of data, i.e.: Side & Horizon (SHDE4), Soil Sample Analysis (SSA), and Land Unit in dbf file, while Site and Horizon is in DataEase formats. The database contains soil physics and chemical property data of each soil horizon from surface to effective soil depth, climate, land surface condi- tions, and other parameters required for soil classification. Currently, database management software for land resources is still based on DOS and is stand alone. The system is not efficient and effectively used as Agri- cultural Land Resource Information System. At present, as a key component of this system requires review and development of new database software is compatible with the development of information technology. This paper explains about development of interactive agricultural land resources information system for op- timizing land resources data utilization. Hopefully, the software can give contributions in national Agricul- tural Land Resources System Information development for supporting food security.展开更多

Their role in sustainability and development planning is thus unique and es- sential. National cartographic centers and national mapping agencies offers example of such national mapping agencies. Accurate information on land and environmental resources is essential to effective land use planning. Key sources of in- formation include topographic maps, aerial photos, satellite images, and data derived from geographic information sys- tems (GIS). At the national level, this information can be used to identify environmental resources, reveal the develop- ment potential of the country, and help promote effective ecological studies and sound land use planning with a land use planning approach. This article begins with some general comments on the importance of land use planning, and outli- nes some current environmental issues and also highlights the connection between roles of Geo-referenced information in land use planning with a sustainable development approach. The discussion describes several key methods of resour- ce identification, with particular emphasis on aerial photography and the existing potentials of Iran in this field. The ar- ticle also discusses the role that the Geo-referenced information and environmental planning play in developing and promoting geographic information system use to sustainable development and finally present proper models to use en- vironmental information and geo-referenced data for sustainable development.展开更多

According to ...Chips are the carriers of ICs (integrated circuits). As a result of design, manufacturing, and packaging and testing processes, chips are typically wholly independent entities intended for immediate use. According to known data, one unit of chip output can drive up to ten units of output in the electronic information industry and 100 units of GDP (Gross Domestic Product). The Chip Information Industry is a strategic industry in most developed countries in Europe and North America. The development of the Chip Information Industry is related to national economies and personal livelihoods. Moore discovered a certain trend after analyzing data: in general, every newly produced chip has twice the capacity of the previous generation, and it takes 18 to 24 months for the next generation to be subsequently invented. This trend has come to be known as Moore’s Law. It applies not only to the development of memory chips but also to the evolutionary paths of processor capability and disk drive storage capacity. Moore’s Law has become the basis of performance prediction in several industries. However, since 2011, the size of silicon transistors has been approaching its physical limit at the atomic level. Due to the nature of silicon, additional breakthroughs in the running speed and performance of silicon transistors are severely limited. Elevated temperature and leakage are the two main sources that invalidate Moore’s Law. To counter these issues, This paper analyzes specific problems challenges in the Chip Information Industry, including the development of carbon nanotube chips and fierce competition in the international Chip Information Industry. In addition, this paper undertakes a critical analysis of the Chinese Chip Information Industry and countermeasures to Chinese Chip Information Industry development.展开更多

The SDLC consists of phases varying from author to author. However, an information systems project can only be successful with intense interaction amongst project manager, systems analyst, system designers and the end users. Viewed from the project manager’s perspective, the SDLC lacks the essence of project management activities. Similarly, end users involvement is not clearly specified. The main aim of this paper is to propose a framework for information systems management and development process which accommodates the views of the different participants. Furthermore, the paper sharpens the concept of conventional SDLC, on the basis of the proposed framework. In addition, tools and methods that are appropriate for the implementation of the framework are herein discussed.展开更多

Information, especially in the present computer age, drives the world, our communication, our decision-making, and our reactions to things happening around us and even beyond. Thus the importance of information to individuals, organizations and even nations cannot be overemphasized. This paper focuses on the usefulness of information to national development, using Nigeria as a case study. Deferent countries have used different strategies and approaches successfully, to initiate and pursue development goals, ranging from import substitution strategy as the case of the Asian tigers, to export-led strategy as has been the case of the developed capitalist countries of the West. In all of this, the role of information in making it possible for Nigeria and other developing countries of the world to know and learn about development strategies from the developed world through internet, radio, television, print, meetings and international conferences has been very rewarding. One major finding from the avalanche of literature consulted is that no one particular strategy can be said to be universally most effective; the success or failure of a particular strategy depends on the prevailing circumstances in individual countries. It is recommended, among others, that economic experts involved in decision-making on national development should always be on the watch out to get the latest information on issues relating to national development.展开更多

As a result of design, manufacturing, and packaging and testing processes, chips are typically wholly independent entities intended for immediate use. According to known data, one unit of chip output can drive up to ten units of output in the electronic information industry and 100 units of GDP (Gross Domestic Product). The Chip Information Industry is a strategic industry in most developed countries in Europe and North America.

文摘Before Information Systems are developed, they must have undergone a process called Systems Development Life Cycle (SDLC) using appropriate methodology. The SDLC consists of phases varying from author to author. However, an information systems project can only be successful with intense interaction amongst project manager, systems analyst, system designers and the end users. Viewed from the project manager’s perspective, the SDLC lacks the essence of project management activities. Similarly, end users involvement is not clearly specified. The main aim of this paper is to propose a framework for information systems management and development process which accommodates the views of the different participants. Furthermore, the paper sharpens the concept of conventional SDLC, on the basis of the proposed framework. In addition, tools and methods that are appropriate for the implementation of the framework are herein discussed.
文摘Information is power. Information, especially in the present computer age, drives the world, our communication, our decision-making, and our reactions to things happening around us and even beyond. Thus the importance of information to individuals, organizations and even nations cannot be overemphasized. This paper focuses on the usefulness of information to national development, using Nigeria as a case study. Deferent countries have used different strategies and approaches successfully, to initiate and pursue development goals, ranging from import substitution strategy as the case of the Asian tigers, to export-led strategy as has been the case of the developed capitalist countries of the West. In all of this, the role of information in making it possible for Nigeria and other developing countries of the world to know and learn about development strategies from the developed world through internet, radio, television, print, meetings and international conferences has been very rewarding. One major finding from the avalanche of literature consulted is that no one particular strategy can be said to be universally most effective; the success or failure of a particular strategy depends on the prevailing circumstances in individual countries. It is recommended, among others, that economic experts involved in decision-making on national development should always be on the watch out to get the latest information on issues relating to national development.

文摘The advancement of the fourth industrial revolution has shaped the integration and interaction of different information, communication and technologies (ICTs) in the merging cyber, physical, and social infrastructures. The impact of ICT has accelerated the progress of the United Nation’s Sustainable Development Goals (UN SDGs) and influenced the evolution of smart, sustainable, stable society development. Making the trustworthy information and communication technologies infrastructure widely available will promote the community innovation needed to stimulate domestic economics, provide decent work, and reduce inequalities. This article attempts to outline a big picture about the International Telecommunication Union (ITU)’s trust provisioning framework, including its motivation, current status, and application for achieving the UN SDGs by 2030. This article first describes the purpose of the UN SDGs and the evolution of the industrial revolution, then demonstrates the challenges of global risks affecting the fourth industrial revolution and the need for trustworthy ICT infrastructures. Subsequently, the article evaluates the ITU trust provisioning framework and assesses its applications in the future knowledge society, trust provisioning ecosystem, and cyber, physical, and social infrastructure toward achieving UN SDGs. Use cases are also presented in this article to show the effectiveness of the ITU trust provisioning framework on achieving UN SDGs.
