Systemic solutions for systemic problems

The systems sciences and cybernetics emerged in the years after World War II. These fields created many new approaches to engineering and management and contributed new ideas to existing academic fields. The new fields also identified similar concepts across a range of fields and began to create a general theory of systems. In addition the systems sciences created a variety of methods for managing complex systems, for example logistics, operations research and computer simulations. In the 1970s there was concern about population and environment balance. Currently there is increasing concern with governance, since the rate of presentation of problems seems to be greater than the ability of our institutions to manage them. This paper will discuss the history of systems science and cybernetics, the questions formulated and the solutions proposed, the difficulties encountered in finding a home within contemporary universities and some exciting lines of research now underway.     

Social responsibility as a next step in development of systemic behavior toward systems solutions of systemic problems of today

Data are clear: humankind is facing a global socio-economic crisis. Global bodies search for solution in ending the neoliberal monopolistic, rather than free market, economy, and in introduction of systemic behavior under the label of social responsibility. To support this effort, the research that is reported about in this contribution, suggests systemic perception of social responsibility to cause the end of abuse, strategy of promotion of social responsibility, and of suitable economic preconditions, supported by several lines of action, which everybody can trigger.     

一类单机随机调度问题解的特征

讨论了加工时间随机的单机调度问题，工件的加工时间服从指数分布，目标函数具有一般形式，涉及工件完成时间与交货期偏差的正规和非正规目标函数，如工件关于交货期拖后时间期望和，工件完成时间关于交货期绝对偏差的期望和等，都是其特殊情形．给出了最优解的特征，包括SEPT(shortest expected pro—cessing time)调度，LEPT(largest expected processing time)调度和关于加工时间参数的A形调度,这些特征可用于确定问题的最优解。     

基于递阶优化算法的一类两层规划问题的解法

提出一种基于分解协调的两级递阶结构优化算法来求解两层规划问题。通过设计解耦变量,两层规划问题被分解成若干相互独立的易于在结构的第一级求解的子问题。而结构的第二级是调整解耦变量使各子问题的解得以改善。算法以一种迭代的方式使第一级求得的子问题的解不断协调,最终达到两层规划的解。算例表明该算法是可行且有效的     

Existence of solutions of generalized quasi-variational relation problems by the inductive relations and some applications

By the inductive relations, this paper first obtains some existence theorems of solutions for generalized quasi-variational relation problems, which are different from other papers. As applications, some existence theorems of solutions for generalized quasi-equilibrium problems and NS-equilibria for noncooperative games under uncertainty are obtained.

Some inverse optimization problems on network

In this paper, the authors consider some inverse problems on network, such as the inverse transport problems with gains (IGTP) and the inverse linear fractional minimum cost flow problem (IFFP). Firstly, the authors give the mathematics model of (IGTP) and an efficient method of solving it under l ₁ norm; Secondly, taking advantage of the optimality conditions, the authors consider the (IFFP) and give a simple method of solving it. Finally, an numerical example test is also developed.     

Knowing as intervention: Reflections on the application of systems ideas

The relation between theory and practice is explored in this paper with respect to an examination of various systems approaches. It is argued that the moment of knowing already contains practical implications in that comprehensiongears practice in certain directions. Practice/application can fulfill the demands of theory through the operation of a self-fulfilling prophecy effect. The way in which theoretical conceptions of systems researchers may constrain practice is explored with reference to the work of Beer, Checkland and Scholes, and Ulrich. In the course of this exploration, alternative views of the way in which viable systems diagnosis, soft systems methodology, and critical systems heuristics may be utilised, are offered.

Systemic Intervention in a University Department: Reflections on Arrested Action Research

This paper reflects on my experience as an insider researcher attempting to use critical systems ideas and practices to promote quality improvement in a university engineering department. Reflection is a key part of learning. This paper is intended to contribute to critically, self-reflective learning for the community of systems practitioners. These reflections on my questions about participation, ethics, politics of process, and the choices and actions resulting from them may help others to formulate their own. The complexity of systems practice places substantial demands on the researcher, particularly in the case of insider, practitioner research. Nevertheless, the exploration of critical systems approaches to critique boundaries and structure ‘problems’ in the core aspects of higher education in locally meaningful ways should continue. While demanding, it still can work to promote learning about authentic quality.
