Abstract An integrated design for manufacture system that performs manufacturability analysis simultaneously in two domains using interchangeable process specific entities is presented. This new approach is illustrated by an integrated system that creates and evaluates parts for manufacture by injection molding using a C-entity, and simultaneously creates and evaluates its mold for manufacture by milling using the fundamental manufacturing entity for milling. The entity for the part manufacturing process is chosen as the complement of the entity for the mold manufacturing process. This obviates the need for converting features from one manufacturing domain to another, and also permits a single uniform data structure to capture the shape characteristics of parts made in the two manufacturing domains. Since all the shapes are represented in the same way, the manufacturability evaluation of the part and the mold is reduced to a small set of algorithms based on an evaluation of the entity’s profile. It is demonstrated that by using process specific entities one can perform manufacturability evaluation of a part without either feature extraction or designing with features. The advantages of using the process specific entities approach for design and manufacturability evaluation over the feature recognition and the design by features approach are enumerated.

In the past, system and subsystem level assessments for propulsion systems have been a long and drawn out serial process, typically taking several months to a year or more. Data exchange from one subsystem group to the next was a manual process. This was particularly the case when different computer platforms were being utilized to run the models. Each group would optimize their particular subsystem as a separate entity. There were no approaches available to facilitate the evaluation of how a particular subsystem, when combined with the engine, would impact the overall integrated system. The availability of tools to facilitate direct interface of the various subsystem models with engine performance decks was not available. As a result, the lead times for various iterations were such that not all of the groups were even working on the same configuration. Fortunately, software technology has been evolving, and the ability to integrate models is now becoming available. This paper describes work in progress of an innovative methodology for high-level integration of complex flight systems. This new approach will facilitate rapid integration and optimization of propulsion and secondary subsystems in a truly concurrent manner, providing capability for top-level evaluation of complex and highly integrated flight system architectures

3D information exchanging and sharing are difficult between CAD, CAPP and CNC systems. To solve this problem, under the support of the National High Technology Research and Development Program, a new approach is brought forward. In section Ⅱ of our explorative paper, a CAD/CAPP/CNC integrated system based on lightweight 3D model is established to manage the information of the whole process of product manufacturing. Fig. 1 in the full paper gives the system’s architecture and functions. In section Ⅲ, we establish an integrated information model based on lightweight 3D model by analyzing each system’s functions and requirements of manufacturing process and the process of data flowing. In order to extract manufacturing features from design features in lightweight 3D model, a feature convertor is established in section Ⅳ. And a 3D feature recognizing prototype system was established and the feasibility of this method was verified.

Modern understanding of the corporation as an integrated system driven by a common goal of profit maximization has brought both economic theory and management practices to a deadlock. Incorrect understanding of the modern corporation’s core, as well as inability to adequately assess them, became one of the causes of the global economic crisis.  One of the promising “reanimation” options of the modern firm theory is the institutional approach. However, this approach is in dire need of measurable operational criteria and indicators that would tie business practices together with their basic theoretical categories: institute, contract, and transaction costs.The scope of this paper is to offer and demonstrate the possibilities of testing methodology for assessing the corporation as an institutional unit of an economic system. To do so, we propose a new approach in the assessment of institutional compliance of the corporations with the expectations of their major subjects.  It is based on estimating the distribution of the gross added value between the subjects.  Moreover, the technique of assessing the level of transaction costs in corporations, based on data accounting, is proposed.  The methods were tested on examples of real Russian metallurgical industry corporations as reported between 2003 and 2012.  The presence of a statistically significant negative connection between the share of value added revenue and level of transaction costs, as well as between the share of value added at the owners disposal and the transaction costs level, was established.  The presence of a statistically significant positive connection between the level of transaction costs and share of value added, at the disposal of workers, was established.

Traditional project management theories and best practices focus primarily on managing the triangular constraints of time, budget and scope (framed in terms of concrete outputs). It has proven valuable and successful in helping organisations to recognise, plan and execute changes to ongoing operations in a disciplined and repeatable manner. However, as the global economy and society continue to become more knowledge based and integrated, this simple industrial model has become increasingly inadequate and, if narrowly focused and pursued, harmful. As for all branches of human knowledge, the problem did not result from knowledge itself but from a misalignment between the complexity of the phenomena and their conceptual representation or knowledge. There have been numerous attempts to extend the industrial model to include additional dimensions of project complexity (Cicmil, et al. 2009). The vast majority of such efforts still suffer from the same root cause of the original model: the mechanical conception of project management as dealing with objective facts (e.g. schedule and budget) on one hand and subjective constituencies (e.g. sponsors and users) on the other. There is a lot of literature on both aspects, but very little integrating the two into a coherent whole. In the author's experience, this lack of integration between the objective and subjective aspects of project management has become the single most critical risk of project success and the greatest advancement opportunity in the profession. The author has spent more than a decade in managing and learning from large-scale projects in organisationally and culturally complex business environments. To cope with the vast complexities of real-life projects, he has had to 'borrow' knowledge and practices from many other fields to supplement traditional project management methods. Two such 'external' disciplines - systems thinking and leadership development - have proven particularly valuable. This case study describes a practitioner's perspective and technique for understanding and extending traditional project management to greater complexities that are typically encountered in an organisational setting. In this conception of and approach to project management, the practitioner (Self), the social environment (Organisation) and the professional responsibilities (Work) are treated as one integrated system. The dynamics of these relationships are shown to be the primary drivers of the health and success of the individual components, in contrast to the mechanical theories and practices of traditional project management. This new approach and associated set of methods is called 'systemic project management'. The case study is organised in the approximate chronological order in which the author developed, tested and expanded this new approach to project management, continuously learning and refining the methods through iterative integration of theory and practice. Part I summarises the core principles of systems thinking and leadership development as applied to project management; Part II lays out a step-by-step practice guide to aid project management professionals in defining, planning and executing a real-life project systemically; and Part III provides an example of how this method can be scaled up in a typical business organisation setting. Due to the length of this case study, only Part III is included in the current issue. Part I and II have already been published in the previous issue of this journal.

In order to achieve continuous navigation capability in areas such as tunnels, urban canyons, and indoors a new approach using least squares support vector machine (LS-SVM) andH∞filter (HF) for integration of INS/WSN is proposed. In the integrated system, HF estimates the errors of position and velocity while the signals in WSNs are available. Meanwhile, the compensation model is trained by LS-SVM with corresponding HF states. Once outages of the signals in WSNs, the model is used to correct INS solution as HF does. Moreover, due to device reasons, there are slight fluctuations in sampling period in practice. For overcoming this problem of integrated navigation, the theoretical analysis and implementation of HF for an integrated navigation system with stochastic uncertainty are also given. Simulation shows the performance of HF is more robust compared with INS-only solution and Kalman filter (KF) solution, and the prediction of LS-SVM has the smallest error compared with INS-only and back propagation (BP), the improvement is particularly obvious.
