Collaborative Project Management: A Systemic Approach to Heavy Equipment Manufacturing Project Management

Quite often over the last decade, heavy equipment manufacturers are trying to improve their project management performance with the use of effective project management methods. However, the challenges encountered aren’t isolated problems and a systemic approach is required. This paper exemplifies how a systemic approach can be applied to heavy equipment manufacturing project (HEMP) management, through of a multifaceted vision. The findings present in the paper are based on a two-year case study in a metallurgic equipment manufacturing enterprise in China. Based on the analysis of HEMP management problems and the contributions on systemic approach application in project management, the paper enriches existing theory by: (1) interpreting the HEMP management system with the top-down disassembly method; (2) developing the collaborative project management approach with a systems view highlighting the project characteristics management and inter-departmental collaboration; (3) making suggestions for systemic approach application in project management. For practitioners and researchers, the findings are particularly meaningful for manufacturing project management and systemic approach application.

基于规模视角的系统重要性银行研究

在放松对银行规模等级设定的基础上，构建了更具一般性和可操作性的改进的三银行模型. 通过引入基于多元极值理论和L函数的三种银行系统重要性指数，规范分析了银行规模对系统重要性的影响. 研究发现，规模是构成银行系统重要性的必要条件但不是充分条件. 同时，运用中国14家上市银行A股交易数据对银行规模与系统重要性的相互关系进行了实证检验，结果与改进的三银行模型基本一致. 无论从理论还是实证角度来看，规模对银行的系统重要性具有重要影响，但当银行规模达到一定程度后，其影响将被弱化，这对于识别和监管系统重要性银行具有重要的理论意义和应用价值.     

A Fresh Look at The Systems Approach and an Agenda for Action: Peeking Through the Lens of Churchman's Aphorisms

This paper critically examines some important topics of systemic thinking to understand how our perception of problems can be enhanced and how the chances of deception can be mitigated while dealing with real-world problems. To achieve this objective, an attempt is first made to scrutinize some of the key issues of systemic thinking by looking through the lens of Churchman's aphorisms at: (1) the illusion of completeness and closure, (2) the meaning of holism, and (3) the concept of ‘Interbeing’. A preliminary ‘agenda for action’ is then laid out suggesting ways for increasing our perception and for minimizing the chances of being deceived in dealing with systems problems in practice.

Strategic Management in Action

This paper sets out to overview the strategic management process and its alignment with a systemic approach and to briefly review the necessary enablers, namely: the presence and practice of learning at the individual, group, and organizational level, a culture of exploration and innovation, which implies a receptiveness to new ideas, and the space or opportunities to practise the skills putting the learnings into action. Having set the study's theoretical context, the paper then explores some of the realities and implications, both for strategic management and the action researcher, by examining two quite different case scenarios from within a large Australian-based financial services organization, the first, Case Study A, involving a more strategic focus, and the second, Case Study B, an operational one.     

Transforming Self and Society: A "Critical Appreciation" Model

This paper sets out to uncover some relationships between reflection, discourse and action. By challenging and synthesizing some polemical arguments concerning the creation, maintenance, and transformation of self and society, a model of self-society dynamics that operates through reflection, discourse, and action is developed. The model of self-society dynamics brings together aspects of self-reflection and ideology-critique (explored in the paper), which it is suggested are required for any intervention (transformative action) to be grounded in locally meaningful ways. By creating a dialog community in which self- and group assumptions can be subjected to validation through discourse, it is proposed that a dynamic balance between individual needs and broader societal aims may be achieved. If individuals can be open to such discourse (i.e., they can become critically self-reflective), then it is argued that possibilities for achieving sustainable change will be significantly enhanced.

Solvability of vector Ky Fan inequalities with applications

This paper aims to study the solvability of vector Ky Fan inequalities and the compactness of its solution sets. For vector-valued functions with the cone semicontinuity and the cone quasicon- vexity in infinite dimensional spaces, the authors prove some existence results of the solutions and the compactness of the solution sets. Especially, some results for the vector Ky Fan inequalities on noncompact sets are built and the compactness of its solution sets are also discussed. As applications, some existence theorems of the solutions of vector variational inequalities are obtained.     

Minimum Hausdorff distance under rigid motions and comparison of protein structures

Hausdorff distance between two compact sets, defined as the maximum distance from a point of one set to another set, has many application in computer science. It is a good measure for the similarity of two sets. This paper proves that the shape distance between two compact sets in R ⁿ defined by minimum Hausdorff distance under rigid motions is a distance. The authors introduce similarity comparison problems in protein science, and propose that this measure may have good application to comparison of protein structure as well. For calculation of this distance, the authors give one dimensional formulas for problems (2, n), (3, 3), and (3, 4). These formulas can reduce time needed for solving these problems. The authors did some numerical experiments for (2, n). On these sets of data, this formula can reduce time needed to one fifteenth of the best algorithms known on average. As n increases, it would save more time.
