Evaluation and Justification of an RFID Implementation : Pilot at IKEA Customer Distribution Centre

Larsson, Björn, Qviberg, Ola January 2004 (has links)
<p>The purpose of this final thesis isto develop a model for justification and evaluation of RFID technology. RFID is a new, relatively untested, technology using radio signals for automatic identification of different objects. Our theoretical frame of references focuses on research about RFID and implementation iss ues, we also conducted case studies and interviews in order to learn about RFID. Most RFID installations of today are Pilots or early adopters wanting to try new technology. A lot of the written sources were reports from consultancy firms or suppliers of technology. </p><p>Implementing RFID in real environment gave important insights into potentials and limitations of the technology. It proved that it is difficult to achieve sufficient readability in a steel environment. We also learned that one should not underestimate the time for installation and tuning in order to meet higher readability. The project finally resulted in an iterative model for justification and evaluation of RFID technology.</p>

An Analysis of the Value Propositions for Integrated 4D BIM-GIS Adoption for Construction supply Chain Management : Assessing Digital Transformation in the Swedish AEC Industry / En analys av värdeskapande förslag för integrerad 4D BIM-GIS-antagande för konstruktionsledning av försörjningskedjan : Bedömning av den digitala transformationen i den svenska ABE-sektorn

Antoh, Robert January 2021 (has links)
Logistics and supply chain in the Architecture, Engineering and Construction (AEC) industry can be seen as coordinated collaboration that is subject to managerial risks. The managerial risks are mitigated by Building Information Modelling (BIM) and Geo-Information Science (GIS), which are two distinctive digital transformative tools which are revolutionizing and accelerating the AEC industry in recent years. Many gains have been achieved concerning the capacity of BIM and GIS to enable collaborative workflows that minimize data loss and reduce inefficiencies in construction. In the past decade, most scholarly literature on BIM and GIS integration for supply chain management have focused on coordination and visualization to improve supply chain operational efficiency. While BIM optimizes visualization and manages the data related to specific projects, GIS coordinates and manages the data related to the outside environment of the project. An integrated BIM-GIS adoption for Construction Supply Chain Management (CSCM) offers value propositions for client and contracting organizations as information/data is seamlessly shared among them to guide decision making at every phase of the construction project.  However, no detailed study has been conducted so far on assessments of the value creation 4D BIM-GIS brings to the AEC industry when espoused for CSCM. To fill this gap, this paper aims to identify and prioritize the value propositions to 4D BIM-GIS adoption for CSCM in the Swedish AEC industry. Based on the reflective perceptions and evaluations of the AEC industry, the paper demonstrated the varied opinions from current active users and those who are yet to adopt 4D BIM-GIS for CSCM. ‘Time savings, ‘Increased efficiency and productivity and ‘Improved communication and information sharing’ were ranked as topmost drivers for 4D BIM-GIS adoption. The paper recommends corporate level training as pivotal in familiarizing workers with the new techniques that combine BIM and GIS in AEC practice. / Logistik och försörjningskedjan inom arkitektur, teknik och konstruktion (ABE) kan ses som ett samordnat samarbete med överhängande ledningsrisker. Riskerna som hanteras kan mildras av Byggnadsinformationsmodellering (BIM) och Geografiskt informationssystem (GIS), som är två digitalt distinkta transformativa verktyg som revolutionerat och påskyndat ABE-sektorn de senaste åren. Många vinster har uppnåtts med avseende på kapaciteten av BIM och GIS, vilket har möjliggjort ett samarbetsflöde som minimerat dataförlust och minskat ineffektiviteten i byggandet. Under det senaste decenniet har den mest vetenskapliga litteraturen om BIM- och GIS-integration för ledning av försörjningskedjan fokuserat på samordning och visualisering för att förbättra effektiviteten i försörjningskedjan. BIM optimerar visualisering och hantering av data, relaterat till specifika projekt, medan GIS samordnar och hanterar data relaterat till projektets omgivning. En integrerad BIM-GIS-antagande för konstruktionsledningen av försörjningskedjan (CSCM) erbjuder värdeförslag för klient- och beställarorganisationer, eftersom information / data sömlöst delas mellan dem för att kunna guida beslutsfattandet i varje fas av byggprojektet. Emellertid har ingen detaljerad studie hittills genomförts om bedömningar av värdeskapandet som 4D BIM-GIS ger till ABE-sektorn när de används för CSCM. För att fylla denna kunskapslucka syftar denna studie till att identifiera och prioritera värdeförslag till 4D BIM-GIS-antagande för CSCM i den svenska ABE-sektorn. Baserat på de reflekterande uppfattningarna och utvärderingarna från ABE-sektorn, visar studien de olika åsikterna från de nuvarande aktiva användare och de som ännu inte har antagit 4D BIM-GIS för CSCM. ”Tidsbesparingar,” Ökad effektivitet och produktivitet” och ”Förbättrad kommunikation och informationsdelning” rankades som de främsta drivkrafterna för 4D BIM-GIS-antagande. Studien rekommenderar utbildning på företagsnivå som en central faktor för att bekanta sig med de nya teknikerna som kombinerar BIM och GIS i ABE-sektorn.
