The Value of RFID Technology Enabled Information to Manage Perishables

We address the value of RFID technology enabled information to manage perishables in the context of a supplier that sells a random lifetime product subject to stochastic demand and lost sales. The product's lifetime is largely determined by the time and temperature history in the supply chain. We compare two information cases to a Base case in which the product's time and temperature history is unknown and therefore its shelf life is uncertain. In the first information case, the time and temperature history is known and therefore the remaining shelf life is also known at the time of receipt. The second information case builds on the first case such that the supplier now has visibility up the supply chain to know the remaining shelf life of inventory available for replenishment. We formulate these three different cases as Markov decision processes, introduce well performing heuristics of more practical relevance, and evaluate the value of information through an extensive simulation using representative, real world supply chain parameters.simulation;value of information;RFID;perishable inventory

Designing Enterprise Resources Planning Application for Integrating Main Activities in a Simulator Model of SCM Network Distribution

Collaborative supply chain is a specific topic in supply chain management and studied by industrial engineering students in supply chain management course. Unfortunately, conventional learning media cannot explain the phenomenon of collaborative supply chain to the students. This study aimed to design a dynamic learning media so that inter-company collaboration and information sharing on the activities of Supply Chain entities can be explained effectively to the students. The problem was solved using 3 (three) steps. First, the distribution network was described using mock up. It consists of miniature trucks, miniature network and miniature of the manufacturer-distributor-retailer embedded with tag and reader of RFID. Second, the Enterprise Resources Planning application was developed for supporting business activities. Third, we developed the integrator consists of monitor’s user interface and practice modules. The result of the research - an SCM-Simulator – will be able to improve learning skills of industrial engineering graduates, especially abilities to identify, formulate, and solve the activities of tactical plan & operational routines of Supply Chain entities. However, distribution module designed is for limited scale laboratory study of simple objects.

From supply chains to demand networks. Agents in retailing: the electrical bazaar

A paradigm shift is taking place in logistics. The focus is changing from operational effectiveness to adaptation. Supply Chains will develop into networks that will adapt to consumer demand in almost real time. Time to market, capacity of adaptation and enrichment of customer experience seem to be the key elements of this new paradigm. In this environment emerging technologies like RFID (Radio Frequency ID), Intelligent Products and the Internet, are triggering a reconsideration of methods, procedures and goals. We present a Multiagent System framework specialized in retail that addresses these changes with the use of rational agents and takes advantages of the new market opportunities. Like in an old bazaar, agents able to learn, cooperate, take advantage of gossip and distinguish between collaborators and competitors, have the ability to adapt, learn and react to a changing environment better than any other structure.

Ensuring the visibility and traceability of items through logistics chain of automotive industry based on AutoEPCNet Usage

Traceability in logistics is the capability of the participants to trace the products throughout the supply chain by means of either the product and/or container identifiers in a forward and/or backward direction. In today's competitive economic environment, traceability is a key concept related to all products and all types of supply chains. The goal of this paper is to describe development of application that enables to create and share information about the physical movement and status of products as they travel throughout the supply chain. The main purpose of this paper is to describe the development of RFID based track and trace system for ensuring the visibility and traceability of items in logistics chain especially in automotive industry. The proposed solution is based on EPCglobal Network Architecture

Ambulance service operational improvement

This document is the accepted manuscript version of a Published Work that appeared in final form in International Paramedic Practice copyright © MA Healthcare, after peer review and technical editing by the Publisher. To access the final edited version see http://www.internationaljpp.com/cgi-bin/go.pl/library/article.cgi?uid=100396;article=IPP_3_3_61_63Since the start of industrialisation in the beginning of the previous century, processes, and technology have evolved drastically. Technology that had been developed for a specific application was found to open new horizons in other domains. A good example is the use of sonar technology on military submarines which eventually found medical applications in medical imaging (Oakley, 1986). The paramedic profession is still considered to be a relatively young profession, and although the clinical scope of practice of ambulance staff has widened there have been few noticeable and significant changes in the way Ambulance Services operate as public service providers. There is, however, great variation in the way pre-hospital emergency care provision is delivered and organised from country to country due for example to historical, cultural, financial, and geographical factors. Other industries are significantly more driven by profit, hence efficiency and reliability are aspects that have a direct and measurable financial impact and it acts as a driver for further developments.Peer reviewedSubmitted Versio

Penilaian kualiti persekitaran dalaman (IEQ) bangunan Akademik Institusi Pengajian Tinggi Awam (IPTA) Malaysia dalam konteks pengurusan fasiliti

Kualiti Persekitaran Dalaman atau Indoor Environmental Quality (IEQ) merupakan komponen penting dalam konteks bangunan mesra alam yang akan menentukan tahap kualiti penghuni di dalam sesebuah bangunan. Secara purata dianggarkan 80% kehidupan seharian manusia adalah berada di dalam bangunan. Ketidakseimbangan IEQ menyumbang kepada Sindrom Bangunan Sakit (Sick Building Syndrome) sekali gus memberi kesan kepada produktiviti para penghuni juga kepada struktur bangunan. Sehubungan itu, kajian ini dilaksanakan untuk mengenal pasti tahap kesedaran pihak pengurusan harta dan fasiliti di Institusi Pengajian Tinggi Awam (IPTA) terhadap IEQ dalam konteks bangunan akademik. Kajian ini juga bertujuan untuk mengukur tahap IEQ dan tahap kepuasan pengguna dalam bangunan akademik di IPTA. Kajian ini melibatkan bangunan akademik di 20 IPTA di Malaysia. Metodologi kajian ini menggunakan pendekatan kualitatif, kajian saintifik dan juga pendekatan secara kuantitatif. Pendekatan Kualitatif digunakan bagi menilai tahap kesedaran pihak pengurusan harta dan fasiliti IPTA melalui proses temubual yang melibatkan 20 orang responden. Manakala pendekatan kedua adalah melalui kajian saintifik ke atas bangunan akademik yang memfokuskan kepada pengukuran elemen keselesaan terma, keselesaan bunyi, kualiti udara dalaman dan pencahayaan. Hasil pengukuran elemen tersebut dibandingkan dengan piawaian dari Malaysia Standard (MS 1525;2007) dan UNESCO. Bagi setiap IPTA, lima buah bilik kuliah dijadikan sampel dengan tiga kali bacaan setiap hari selama dua hari diperolehi bagi mendapatkan bacaan purata. Seterusnya, melalui pendekatan kuantitatif, data yang diperolehi melalui kaji selidik melibatkan 500 responden dan dianalisis menggunakan perisian Statistical Package for Social Science (SPSS). Hasil kajian menunjukkan kesedaran para pengurus harta dan fasililti di IPTA terhadap IEQ adalah baik tetapi masih ada beberapa kelemahan yang perlu ditambahbaik. Hasil ujian saintifik yang diperolehi menunjukkan bacaan bagi suhu dalaman, hanya UniSZA, UTHM dan UniMAS yang menepati piawaian, manakala bagi pencahayaan, UM, UIAM, UPSI, USM, UniSZA, UTM, UTHM, UTeM, UMS dan UniMAS berada di bawah tahap piawaian ditetapkan. Bagi keamatan bunyi, hanya UM, UPM, UPSI, USM dan UniMAP yang menunjukkan bacaan pada piawaian ditetapkan. Keseluruhannya menunjukkan bacaan berada pada tahap yang sederhana dan masih lagi memerlukan pernambahbaikan. Kajian ini turut mempamerkan bacaan purata bagi setiap elemen IEQ bagi bangunan akademik seluruh IPTA. Penemuan hasil kajian ini dijangka dapat membantu pihak pengurusan harta dan fasiliti IPTA dalam usaha menambahbaik tahap IEQ dalam bangunan akademik di kampus universiti sekaligus dapat meningkatkan tahap pengurusan fasiliti dalam mencapai tahap kelestarian kampus IPTA di Malaysia

Radio frequency identification (RFID) technologies for locating warehouse resources: A conceptual framework

Copyright @ 2012 Information Technology SocietyIn the supply chain, a warehouse is a crucial component for linking all chain parties. It is necessary to track the real time resource location and status to support warehouse operations effectively. Therefore, RFID technology has been adopted to facilitate the collection and sharing of data in a warehouse environment. However, an essential decision should be made on the type of RFID tags the warehouse managers should adopt, because it is very important to implement RFID tags that work in warehouse environment. As a result, the warehouse resources will be easily tracked and accurately located which will improve the visibility of warehouse operations, enhance the productivity and reduce the operation costs of the warehouse. Therefore, it is crucial to evaluate the reading performance of all types of RFID tags in a warehouse environment in order to choose the most appropriate RFID tags which will enhance the operational efficiency of a warehouse. Reading performance of active and passive RFID tags have been evaluated before while, semi-passive RFID tag, which is battery-assisted with greater sensitivity than passive tags and cheaper than active tags, has not been examined yet in a warehouse environment. This research is in- progress research and it seeks to (i) provide a general overview of the existing real-time data management techniques in tracking warehouse resources location, (ii) provide an overall conceptual framework that can help warehouse managers to choose the best RFID technologies for a warehouse environment, (iii) Finally, the paper submits an experiment design for evaluating the reading performance of semi-passive RFID tags in a warehouse environment

Impact of RFID information-sharing coordination over a supply chain with reverse logistics

Companies have adopted environmental practices such as reverse logistics over the past few decades. However, studies show that aligning partners inside the green supply chain can be a substantial problem. This lack of coordination can increase overall supply chain cost. Information technology such as Radio Frequency Identification (RFID) has the potential to enable decentralized supply chain coordinate their information. Even though there are research that address RFID on traditional supply chain, few researches address how to coordinate RFID information sharing in a green supply chain. We study, through simulation experiments, two types of RFID information-sharing coordination under different configurations related with their inventory policies: basic and advanced. Statistical analyses show that better results can be presented in advanced RFID configuration given new coordination and inventory policy decisions presented. In addition, these findings shows what are the RFID information-sharing coordination that can provide better system improvement depending on the supply chain scenarios and factors
