Manufacturers have already deployed RFID technology in products that could be spoiled during transportation due to temperature extremes. For example, frozen chicken has a high risk of salmonella contamination if it becomes too warm for a long time. If the temperature exceeds a certain threshold, a permanent electrical change occurs in the RFID-based label. When the RFID reader interrogates the tag, it will respond with data that indicates the warning state as well as its ID. In this paper, a mobile diagnosis system based on RFID (radio identification) for food safety is developed. The developed system consists of a mobile server and a remote server. In the mobile server, a PDA equipped with RFID CF reader card is used to acquire the food temperatures from RFID sensors. Moreover, the multi-sensor fusion algorithm is applied to integrate the sensor information. X-bar chart or trend chart is used to observe the operation condition of the food. Subsequently, further analysis can be executed over the remote diagnosis server, if necessary. And through wireless network, related personnel can hold an on-line dialogue for troubleshooting

This paper proposes a design method of Hinfin control performance for structural systems using Takagi-Sugeno (T-S) fuzzy model. The structural system with tuned mass damper is modeled by T-S type fuzzy model. By using parallel distributed compensation (PDC) scheme, we design a nonlinear fuzzy controller for the tuned mass damper system. According to the control system, a sufficient stability condition is derived in terms of Lyapunov theory and this control problem is reformulated into solving linear matrix inequalities (LMI) problem.

CPC is a compound priority control strategy used for scheduling semiconductor wafer fabrication. The compound priority of wafers is calculated according to their current processing step, to the amount of wafers waiting for processing in current step buffer, in upstream step buffer, and in downstream step buffer. Wafers with the highest compound priority are dispatched to certain machine to be processed. Compared to common used scheduling strategies, CPC strategy exhibits high performance in reducing total amount of WIP, decreasing cycle time and its standard deviation, and increasing the throughput rate

In the normal condition, the front wheels follow the control trace of the driver and rear wheels follow the direction of the vehicle. The vehicle will spin and lose the control trace of the driver if the traction force is greater than the friction force. Therefore, a vehicle should maintain an adequate slip ratio of the tires and follow the control trace of the driver. This paper describes a fuzzy controller for hybrid traction control system in hybrid electric vehicles (HEVs) that prevents the spinning of the drive wheels during take-off and acceleration through targeted, brief brake impulses in motor torque. The task is to have the fuzzy supervisory controller generate the electric brake torque, for motor of a HEV. The electric brake torque is treated as reference input regenerative braking torque, for lower level control modules. When these lower level motor controller tracks its reference input, the desired slip ratio, can be reduced. Emergency lane change and tire slip ratio change simulations are performed to show the effectiveness of the control. The efficiency and easy implementation of the fuzzy controller lead to the conclusion that fuzzy logic is an adequate and promising framework for hybrid traction control system in hybrid electric vehicles.

This paper presents the behavioral semantics of the high level modeling formalism sensor activation graphs (SAG). SAG simplifies discrete event modeling of physical systems with binary input and output signals, typically manufacturing systems. The SAG framework is object oriented and contains several convenient features that is believed to make formal modeling manageable even for full-size manufacturing systems. An algorithm for transforming a SAG model into finite state automata is presented, which enables formal verification and synthesis

In this paper, we propose a decomposition and optimization method for Petri nets to solve routing problems for automated guided vehicles in semiconductor fabrication bays. An augmented Petri net model is developed to represent concurrent motion for multiple AGVs. The routing problem to minimize total transportation time is formulated as an optimal firing sequence problem for the proposed Petri net. The optimization model is decomposed into several subproblems which can be solved by Dijkstra's algorithm in polynomial order. The effectiveness of the proposed method is evaluated by several numerical examples

Building emergency evacuation has long been recognized as an important problem, since safety is a major concern for building occupants. The paths selected for egress should be pressurized with fresh air through HVAC airflow control. The problem is to minimize the egress time by reconfiguring HVAC units and selecting egress paths for occupants in a building, subject to path capacities and HVAC system limitations. The interdependency of the transportation and HVAC systems and the combinatorial nature of discrete optimization make this a challenging problem. For simplicity, steady-state airflow analysis over each duct is used, and dampers are considered either fully open or fully closed. Our key idea is to make full use of traditional network flow models for egress while considering the fan power capacity as a constraint. The problem is solved by iteratively using a maxflow algorithm while exploiting dominance properties to reduce the search space. An optimized reconfiguration of the HVAC is established, resulting in significant improvements in evacuation time

This paper attempts to investigate methods through which RFID-enabled technologies may be used to streamline and improve airline baggage handling processes. The current process for airline baggage handling relies heavily on the use of barcodes and is highly unreliable. Even though the value of RFID-enabled technologies, in handling passenger bags, is generally accepted in the industry, the adoption of these technologies is hindered by concerns relating to inadequate return on investment on them. In this paper, we attempt to address this issue by highlighting scenarios in the baggage handling process where RFID-enabled technologies may be uniquely positioned to create value. In particular, with the help of fault trees we identify exceptions that commonly arise in the baggage handling process and identify RFID-enabled solutions that may be implemented to manage these exceptions. We also discuss the design of a decision support system that can be implemented to automatically handle baggage handling exceptions using RFID tag information
