This paper first describes the concept of a microfactory and its design basics. The microfactory is a desktop-type miniature manufacturing system consists of miniature machine tools and manipulators. Since the prototyped microfactory was able to perform the whole process of machining parts and assembling them to a miniature ball bearing, it was able to say that it has a significant capability for micro mechanical fabrication. However, the possibility of the microfactory to improve manufacturing efficiencies of micro mechanical fabrications has not been considered enough. In the paper, the author proposes an evaluation method to calculate efficiencies of the system, based on the required time for each process, machine cost, operator's cost and environmental impact measured by energy consumption, using the abovementioned microfactory as an example. Through the analysis the paper tries to evaluate the system efficiency and show the procedure to determine the optimum system configuration. Finally, the paper concludes that a microfactory-like reconfigurable system will be useful in improving productivity, by combined with a proper evaluation method system efficiency.

In this paper, the architectural parameters optimization of a three degree-of-freedom (DOF) parallel kinematic machine (PKM) with three PUU (prismatic-universal-universal) links is performed using the efficient particle swarm optimization (PSO) to achieve the best accuracy characteristics. The error transformation matrix (ETM) is derived based on the differentiation of kinematic equations, and the lowest value of the maximum singular value of the ETM over a usable workspace is considered as an error performance index for the optimal design. To emphasize the efficiency of the PSO method, both the traditional direct search method and the genetic algorithm (GA) are compared with it. The simulation results demonstrate that the PSO is the best method for the optimization, and the analysis results are valuable in designing and controlling a 3-PUU PKM for machine tool applications

The problems of supply chains are research hot points now. And the evolutionary game theory gradually becomes a new and effective method to these problems. An evolutionary game model learning through imitation is proposed on the relationship between retailers' promotion and suppliers' inspection. It is found that the dynamics process and evolutionary stable strategies of this model equal to some type of replicator dynamics model's. But, there are differences of meaning and time scale between imitation learning and replicator dynamics. At last, a numerical example is studied to illustrate dynamic evolutionary process of this model learning through imitation.

An improved distributed coordination algorithm for multi-agent system is presented. Combined an coverage control method with rolling window method (RWM) based on r-limited Voronoi partitions, the algorithm has a natural priority to safety, goal convergence, and formation keeping, even if the location and shape of all existing obstacles are unavailable. The theoretical properties are discussed in the paper and there are numerical simulations illustrating its efficiency.

Robot programs typically manage a substantial amount of dimensioned data. However, existing robot programming tools do not directly support the description and manipulation of dimensioned quantities. A new data type has been proposed for managing dimensioned data in robot software. The design removes much of the hard work of using and ensuring correctness in dimensional data and allows mixing of units using dimensional analysis. An initial implementation has been created by extending the Python interpreter. This paper evaluates the proposal for dimensioned data in robotic systems, using established qualitative evaluation criteria for programming languages, based on the design and implementation, human factors, software engineering, and the application domain. In addition the paper shows that the method can be formalised, and that it is able to support coordinate systems. A set of unit tests is reported for the implementation. Together these evaluations show the proposed dimensioned data system to be implementable, self-consistent, and useful in robotics. The proposed design improves robot programming where dimensioned data is involved

This paper aims to contribute to offshore risk analysis by proposing a methodology to model causal relationships focusing on human and organisational errors. The proposed methodology uses James Reason's "Swiss cheese" model to form a generic offshore risk analysis framework and tailors Bayesian Network (BN) to fit into the framework to construct a causal relationship model. A case study of the collision risk between a Floating Production, Storage and Offloading (FPSO) unit and authorised vessels caused by human and organisational factors (HOFs) during operations is used to illustrate the application of the proposed methodology. This paper shows that James Reason's "Swiss cheese" model and BN can be jointly used in offshore risk analysis

Due to the proliferation of new technologies and demands for dexterous robotics manipulators, multi-degree-of-freedom (MDOF) actuators are widely sought after. These actuators are utilized primarily in the assembly sectors, precision machining and active tracking devices. Prior to realizing a feasible MDOF actuator for any practical use, positional closed loop feedback is of paramount importance. To date, commercially available encoders are mainly limited to single-DOF sensing. Furthermore, integration of these sensors inherently introduces mechanical linkages that compromise the overall performance of the system. This paper introduces an alternative approach in 3-DOF motions sensing leveraging on contactless sensing of anisotropic magneto-resistive (AMR) sensors. The theory and design methodology of this sensing method is being discussed and presented. Experimentation was also conducted for conceptual verification on existing spherical actuator. The uniqueness of this technique lies in the exploitation of existing magnetic field generated from the rotor. The test platform being established is expected to lay the foundation for optimizing key parameters. With the successful implementation of this new sensing system, future development will be focusing on real-time measurement and control.

Accurate, distributed localization and motion analysis algorithms are needed for a variety of mobile wireless sensor network applications. The research on mobile nodes localization and motion analysis in real time will continue to grow as sensor networks are deployed in large numbers and as applications become more varied. In this paper, we introduce a localization and motion analysis parameter estimation algorithm in mobile wireless sensor networks by using pseudo-linear-Kalman filtering, maximum likelihood estimator (MLE) and extended Kalman filter (EKF) techniques. The Cramer-Rao bound (CRB) is also given in this study. Simulations show that the algorithm performs well even with noisy RSS and TOA estimates in the sensors. We apply MLE, EKF and the EKF-based estimator to demonstrate the best bias and variance performance, but the algorithm may not be robust for all random sensor deployments.

At present, many production scheduling systems have been developed. However, a lot of customization according to individual production environment is required, and then a large investment for development and maintenance is indispensable. Therefore now the direction to construct scheduling systems should be changed. The final objective of this research aims at developing a system which is built by it extracting the scheduling technique automatically through the daily production scheduling work, so that an investment will be decreased. This paper shows a prototype of Gantt chart interface system that emulates the production scheduling work on papers. Through the analysis of operator's operations, this paper proposes how to extract the master information required by production scheduling. Using the information, the scheduling operators can be supported to accelerate the scheduling work easily and accurately without any restriction of scheduling operations. By installing this extraction mechanism, it is easy to introduce scheduling system without a lot of expense for customization. In this paper, the extraction mechanism of the master information and operator support functions are proposed through a model expressing a scheduling problem.
