A multi-cluster tool is composed of a number of single-cluster tools linked by buffering modules. The capacity of a buffering module can be one or two. Aiming at finding an optimal one-wafer cyclic schedule, this work explores the effect of two-space buffering modules on the performance of a multi-cluster tool. The tool is modeled by a kind of Petri nets. The dynamic behavior of robot waiting and tasks, process modules, and buffers is well captured by the net model. With the model, this work shows that there is always a one-wafer cyclic schedule that reaches the lower bound of the cycle time of a process-dominant tool. Furthermore, a constant-time algorithm is revealed to find such a schedule for the first time for such multi-cluster tools. An illustrative example is given to show the application and power of this new method. © 2014 IEEE.

Manufacturing systems need to integrate information from several sources, manage their business processes and coordinate the shop floor in order to meet the schedule at reduced costs. Holonic manufacturing has been proposed to solve these problems and has been normally implemented using agents. However, these implementations are not widely used due to their cost and limited interoperability. In this work, an approach that combines a service-oriented architecture with a multi- Agent system is proposed. A list of rules is designed for deciding how to implement each holon, and is applied to the level 3 activities of ISA-95. The adoption of an enterprise service bus is suggested for decoupling service consumers and producers, and using a complex event processing engine is recommended to detect trends from the day- To-day operations of a plant. This approach is then applied to a grinded ceramic tile manufacturing plant, deriving a general architecture and an implementation of a service-based holon based on the ISA-95 object model, with a human-facing side (a website) and a machine-facing side (a Web Service). © (2014) Trans Tech Publications, Switzerland.

RETRACTED ARTICLE: Support vector regression methodology for prediction of input displacement of adaptive compliant robotic gripper

Applied Intelligence 2014年第3期41卷 887-896页

Pavlović Faculty of Mechanical Engineering Deparment for Mechatronics and Control University of Niš Niš Serbia Department of Computer Science Chalous Branch Islamic Azad University (IAU) Chalous Iran Department of Computer System and Technology Faculty of Computer Science and Information Technology University of Malaya Kuala Lumpur Malaysia Department of Information System Faculty of Computer Science and Information Technology University of Malaya Kuala Lumpur Malaysia Computer Engineering Department Islamic Azad University of Karaj Karaj Iran

The prerequisite for new versatile grippers is the capability to locate and perceive protests in their surroundings. It is realized that automated controllers are profoundly nonlinear frameworks, and a faultless numerical model is hard to get, in this way making it troublesome to control utilizing tried and true procedure. Here, a design of an adaptive compliant gripper is presented. This design of the gripper has embedded sensors as part of its structure. The use of embedded sensors in a robot gripper gives the control system the ability to control input displacement of the gripper and to recognize specific shapes of the grasping objects. Since the conventional control strategy is a very challenging task, soft computing based controllers are considered as potential candidates for such an application. In this study, the polynomial and radial basis function (RBF) are applied as the kernel function of Support Vector Regression (SVR) to estimate and predict optimal inputs displacement of the gripper according to experimental tests and shapes of grasping objects. Instead of minimizing the observed training error, SVR poly and SVR rbf attempt to minimize the generalization error bound so as to achieve generalized performance. The experimental results show that an improvement in predictive accuracy and capability of generalization can be achieved by the SVR approach compared to other soft computing methodology.

Confronted with inventory as a cost, the main efforts in today's remanufacturing environment are towards reducing cost while maintaining the level of service and improving the overall system's performance. Economic Production Quantity (EPQ) model for joint manufacturing and remanufacturing has received increasing attention over the past decades as an inventory policy for production planning and control;however, having unrealistic assumptions, such as deterministic demand, return and processing time made it far from being practically exploited by the managers as a technique to address the companies' real-life problems. An inventory system with both manufacturing and remanufacturing in which product returns and demands are stochastic is developed using ProModel™ simulation software. An investigation on a pull remanufacturing policy, where demand could be satisfied from either new or remanufactured items, while the cost of remanufacturing is cheaper than manufacturing is also conducted. The optimal solutions are obtained through using SimRunner™ to find the optimal manufacturing, remanufacturing and reorder point quantity, while the operational cost of the system, including the cost of setup, inventory holding, WIP and backorder is minimized. The results illustrate the need for manufactured products, as the return flow is highly variable. A sensitivity analysis is also carried out on the influence of changing decision parameters over the robustness of the objective functions.

RETRACTED ARTICLE: Soft computing methodologies for estimation of bridge girder forces with perforations under tsunami wave loading

引用

Bulletin of Earthquake engineering 2014年第3期13卷 935-952页

作者： Akib, Shatirah Rahman, Sadia Shamshirband, Shahaboddin Petković, Dalibor Department of Civil Engineering University of Malaya Kuala Lumpur Malaysia Department of Computer System and Technology Faculty of Computer Science and Information Technology University of Malaya Kuala Lumpur Malaysia Department of Computer Science Chalous Branch Islamic Azad University (IAU) Chalous Iran Department for Mechatronics and Control Faculty of Mechanical Engineering University of Niš Nis Serbia

Tsunamis pose a great threat to coastal infrastructures. Bridges without adequate provisions for earthquake and tsunami loading generally are vulnerable when a tsunami occurs. During the last two disastrous tsunami events (i.e., the tsunami in the Indian Ocean and the tsunami that struck Japan), many bridges were damaged by the waves created by the tsunamis. In this paper, in order to address this crucial problem, we used soft computing techniques to design and develop a process that simulates the effects of perforations in the girders of bridges on reducing the forces applied on the bridge when a tsunami occurs. Soft computing methods have very good learning and prediction capabilities, which make it an effective tool for dealing with the uncertainties encountered when waves are generated by a tsunami. Laboratory experiments were conducted to acquire a better understanding of the effects of the factors involved and to check the data required for the soft computing methods. In order to predict the effects of perforations in the girder of a bridge on force reduction, novel intelligent soft computing schemes, support vector regression (SVR), and adaptive neuro-fuzzy inference system (ANFIS) were investigated. In this study, the polynomial, linear, and radial basis function were used as the kernel function of the SVR to estimate the effects of perforations in a girder of a bridge. The performances of the proposed estimators were confirmed by simulation results. The SVR results were compared with the ANFIS results, and we observed that an improvement in predictive accuracy and the ability to generalize were achieved by the ANFIS approach.

The 4-Wheel Skid-Steering Mobile Manipulators (4W-SSMM) have been widely used in many complex task environments, in which, it often encounter all sorts of complicated driving conditions. In these situations, excessive slipping would be likely to happen, and the robot's tracking stability cannot be assured. In order to solve this problem, a stability control scheme which is based on the slip ratio and an active mechanical arm is proposed in this paper. In this scheme, the load of tire can be changed by changing the motion attitude of the manipulator, the excessive slip can be avoided and the tracking stability of 4W-SSMM can be assured. The dynamic model of it is derived in this paper. The results of the experiment and simulation show that, the model constructed in this paper can reflect the relationship between the motion attitude of the manipulator and the load of tire accurately, and the scheme proposed in this paper is feasible and effective.

This video presents our preliminary work towards addressing the ladder climbing event in DARPA Robotics Challenge (DRC) using DRC-Hubo robot. A ladder-climbing motion planner is developed which generates a collision-free, stable quasi-static trajectory for execution. Compliance control is enabled on arm joints to compensate for the calibration error, modeling error and control error. We have demonstrated that DRC-Hubo can robustly climb a variety of ladders in simulation and successfully climb a ship ladder on the hardware.
