Information Flow Scheduling in Concurrent Multi-Product Development Based on DSM

Multi-product collaborative development is adopted widely in manufacturing enterprise, while the present multi-project planning models don＇t take techni- cal/data interactions of multiple products into account. 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.

Research and Application of Management Information Systems

Management Information System provides an effective way for enterprises to improve their competitive abilities. It presents a framework for improving the management models through the design and implementation of effective and high-quality MIS. So it is very important to the modem management of corporations. ERP （Enterprise Resource Planning） system is one of the core parts of MIS, which solves the matter of management model mainly. ERP is a popular method enabling the business processes required to compete with the globalization. The thesis cites SAP R/3 to introduce the general structure and function of ERP. Global Enterprise Resource Planning Implementation is increasingly becoming the successful choice of MIS.

The Role of Information Security Development （ISD） in Effective Information Security Management （ISM） Implementation in the Banks： A Nigerian Case

This research discusses the role of information security development （ISD） using organizational factors such as information security plans, information security awareness, perceived quality training programs, information security policies and procedures, and organizational culture in effective information security management （ISM） implementation in the banks （a Nigerian case）. This paper explores the existing literature and a proposed framework that consists of ISD such as information security plans, information security awareness, perceived quality training programs, information security policies and procedures, and organizational culture in ISM implementation. ISD factors are found to be statistically significant, because it motivates an organization to implement effective ISM in the banks. Hence, it could be said that the role of ISD practices in an effective implementation of ISM among banks in Nigeria will be of great value.

APPROACH TO INTEGRATED PROCESS PLANNING SYSTEM ARCHITECTURE

A series of researches on process planning system architecture is described.The definition of process planning in CIMS, a unified description for work procedure of various CAPP systems,including retneval,variant and generative systems,and the information models about part, manufacturing facility are provided to form scientific basis for process planning automation where a Part Model based on Feature and a Production Environment Model based on Work-Element are to be important supports for implementation of the integrated process planning system.These concepts are applied to the development of a prototype system SIP,which is suitable for box-type mechanical parts and consists of three subsystems:CAD,CAPP and NCP.They are linked together by neutral files as interfaces. This is a successfol implementation for engineering integration.

Big Data Resource Planning for Food Safety: a Preliminary Exploration of the “Environment, Food and Health” Information Chain

Environmental pollution, food safety and health are closely linked. A key challenge in addressing the problem of food safety and protecting public health is building an integrated knowledge base to inform policy and strengthen governance. This requires breaking down the trans-departmental information barrier across the environment, food and health domains to ensure the effective flow of data and the efficient utilization of resources, and facilitate the collaborative governance of food safety. Achieving this will be crucial for the development of health and medical care in China in the era of big data. Currently, the information resources commanded by various departments are incomplete and fragmented. Data resources are also organized in vertical silos and there is a lack of data sharing within and across policy streams. To provide the basis for more effective integrated collection and analysis of data in future, this study summarizes the information resources of various departments whose work relates to interactions between environment, food and health, and presents measures to strengthen top-down design, and establish unified data standards and a big data sharing platform. It also points to the need for increased training of data analysts with interdisciplinary expertise.

The Planning of Beijing Shangdi Information Industrial Base

The Shangdi Information IndustrialBase is a hi-tech park under construction in Beijing.The planning,while employing the conventionalregulatory detailed planning,has laid more emphasis onthe urban landscape design so as to create a perfect envi-ronment and embody the style and features of new gen-eration park of science and

Employee Stock Ownership Plans and Stock-price Informativeness

This study examines the impact of employee stock ownership plans(ESOPs)on stock-price informativeness in Chinese stock markets.Its findings indicate that firms implementing ESOPs experienced an average 11.89 percent increase in stock-price informativeness.The plans improved stock-price informativeness through increased external attention and supervision.An event study shows that ESOPs gave rise to an announcement effect,driven by anticipated performance improvements and the novelty associated with ESOPs.A mechanism analysis demonstrates that the implementation of ESOPs attracted market attention,and the increased market supervision resulting from this mitigated the moral hazards of management associated with ESOPs.Plans with more positive signals exerted a greater influence.Notably,ESOPs that prioritized management incentives gained more recognition in the market.As the incentive effects of ESOPs were weaker than those of equity incentive plans and the ESOPs lost novelty over time,the annual announcement effect diminished gradually.These findings underscore the necessity of strengthening ESOP incentives for continued optimization of priceefficiency.
