RFID tag is detected by an RFID antenna and information is read from the tag detected, by an RFID reader. RFID tag detection by an RFID reader is very important at the deployment stage. Tag detection is influenced by factors such as tag direction on a target object, speed of a conveyer moving the object, and the contents of an object. The water content of the object absorbs radio waves at high frequencies, typically approximately 900 MHz, resulting in unstable tag signal power. Currently, finding the best conditions for factors influencing the tag detection requires very time consuming work at deployment. Thus, a quick and simple RFID tag detection scheme is needed to improve the current time consuming trial-and-error experimental method. This paper proposes a back-propagation learning-based RFID tag detection prediction scheme, which is intelligent and has the advantages of ease of use and time/cost savings. The results of simulation with the proposed scheme demonstrate a high prediction accuracy for tag detection on a water content, which is comparable with the current method in terms of time/cost savings.

Quality Progress

Rapid change is arguably the most unsettling marketplace reality that companies, their customers and employees must cope with today. In this environment of relentless and unpredictable change, manufacturers are finding they must be `agile'. As mass production systems are challenged to meet the new, changing demand from the worldwide marketplace, agility provides companies with a comprehensive, strategic response. This change in the business environment will once again necessitate a change in all practices and functions. Included in this are evolutionary changes in quality away from satisfying consumers with reliable, uniformly made items to gratifying them with individualized goods and services.

This paper addresses Fractional cell formation in Group Technology implementation, where part of the production facility is redesigned into manufacturing cells. The fractional cell formation issue is important in manufacturing cell design, because it may not be possible to economically convert the entire facility to manufacturing cells. The authors discuss the issues in modeling fractional cell formation problems and they develop efficient algorithms to group the facilities into manufacturing cells and a remainder cell. Algorithms are tested using a variety of matrices including those from real-life situations to demonstrate the potential applicability of the proposed approach.

This paper discusses the application of a Decision Support System (DSS) for making operational decisions in a food processing industry. A model is developed for determining the optimum production scenario for every week based on the tradeoffs between service levels, costs, inventories, changeovers and capacity. The experiences of the authors in designing, developing, and implementing the Decision Support System are shared in this paper.

This paper presents algorithms to minimize the variance of completion time (CTV) when n jobs have to be processed on two machines. All the jobs visit the machines in the same order or technological sequence. These algorithms are applicable in manufacturing systems where both the facilities could be within the factory or situations where one facility represents the bottleneck machine within the shop floor while the other represents the subcontractor facility. The problem is also applicable in file handling systems where two individuals have to process files in a fixed sequence. The paper presents heuristic algorithms that identify the sequence of jobs that minimizes completion time variance. The solutions are compared with a lower bound and are found to give results in the range of 5–10% deviation from the lower bound. In addition, the simulated annealing algorithm developed in this paper gives the optimum solution for all the problems tested up to 11 jobs.

... Earlier work with the Greenfield Coalition had demonstrated the value of attention to these processes. 4,5,6,7 Another important component of module development from the Greenfield Coalition design process was placing the module within a learning context. This context requires defining the motivation, the objectives, and the prior knowledge of the participants. ...

... Examples of the complexity of the control strategy for this kind of solutions are reported in [5] for rolling approach, in [6] for sliding approach and [7] for gaiting approach. The choice of using a parallel gripper is justified in the manufacturing field by Bracken [8], who proposed a geometrical classification of parts to be gripped into six shape categories (i.e., spherical, rectangular, cylindrical, triangular, holed and flexible) and stated that the gripper able to deal with most shapes is the parallel two-jaw gripper. ...

... This complexity of lean has produced awareness in manufacturers and researchers of the whole world to apply such tools that are beneficial for lean in the system (Swank, 2003), to acquire the best results like improve lead times, customers demand and controlling cost and quality (Goldsby, Griffis, & Roath, 2006;Rafique, Ab Rahman, Saibani, Arsad, & Saadat, 2016). In order to do so, the lean tool of value stream mapping is beneficial since it categorizes the process to value added and non-value added times, laying groundwork for improvements (Christian & Zimmers, 1999). Lean can be considered as a philosophy which helps to make the system effective and efficient for industries. ...

... It has been subsequently applied in the manufacturing scheduling context as it is stated to be an appropriate objective for just-in-time production systems, or any other situation where a uniform treatment of the jobs is desirable (see, e.g., in [21][22][23][24]). In the flow shop/job shop scheduling context, it has been employed by [25][26][27][28][29][30][31][32]. ...

Moreover as Bozkir and Akcapinar Sezer point out, approaches which forecast the demand for a served menu can present many benefits to institutions as it would optimize the balance of supply and demand in name of saving resources and work power [1]. At this point, Sundararajan et al. address the importance of information technology and services, computer aided tools providing intelligence to make real time decisions [3]. With this motivation, Sundararajan et al. implemented a decision support system for making operational decisions in food processing industry which is based on optimization techniques and focuses on determining optimum production scenario for every week based on the tradeoffs between service levels, inventories, costs and capacity [3]. ...

... Wireless communication between the tag and reader is influenced by factors such as the type of reader, the position of the tag, the direction of the tag, the material of the object to which the tag is attached, the angle of the antenna, and the speed of the object. [6] When other radio frequencies interfere with the frequency with which the tag and reader communicate, the reader cannot identify the tag successfully. For the reasons stated above it is very clear that the object attached to the tag or material contained in the surrounding area can result in changes in tag performance and reader. ...
