This semester, I am studying Mrs. Pang’s lessons named “Designing and Managing the Supply Chain”. After watching the videos of MIT open class about ”RFID Technology in SCM”, I tried to make a research based on the video about the packaging issues referred to RFID. In my research, I first had a review of the video, and then discussed the RFID problems in a “SCM” manner. SCRIPT OF THE VIDEO [1] 1 st Lecturer: Rob Clark from Michigan University, the school of Packaging Beginning: 0:00 ~ 2:07 An opening remark. 2:21 Quoting “Packaging is the center of the universe.” What is packaging: 3:06 Different levels of packaging —— Primary container(bottle), secondary container(six-pack), tertiary container(shipping case), and so on. 3:53 Different requirements for different industries —— consumer sector(retail outlets), industrial sector, military, medical pharmaceuticals, etc. 5:22 Cost and price are not equal —— Cost includes insurance cost, liability cost, opportunity costs, good will costs. You have to balance the costs before you can make the business case; Price is what you pay for something. 5:52 Environmental issues to balance —— Your product plus your package at worst has to equal the environment that you’re going to ship it through.

Problem 3: What are the impacts of different materials on RFID? What are the other facts that can affect RFID? Problem 4: What are the obstacles to packaging with RFID? How to solve them? Problem 5: How would packaging be in the future with the development of RFID? SOLUTIONS Answer 1: (What is packaging? What kind of role is packaging playing in the supply chain? ) The definition of packaging is: 1) “Packaging is the container or covering that something is sold in.” [2] 2) “The process of wrapping goods.” [3] In the video, packaging is characterized by: 1) Different levels (bottle, six-pack, shipping case …). 2) Different requirements for different industries. 3) Having the function of containment, communication, and protection (both the product and the environment). The role packaging is playing in the supply chain is: Withstanding the rigors of distribution, manual and mechanical handling, warehousing and storage, and give the ultimate user a sense of value. Answer 2: (What is RFID? How is RFID used in packaging? ) The full name of RFID is Radio Frequency Identification. The description of RFID is: RFID Radio Frequency Identification is a kind of-touching automatic identifying technique. [4] The approaches to use RFID in packaging are: We can use a reader to get the information stored in the RFID tags which are put on the package. RFID tags can be either passive, semi-passive as semi-active, or active [5]: Passive ones absorb the energy sent by the reader and use the energy to send the information back to the reader. Semi-passive ones use batteries to activate the tags and enable the antenna to make full use of the electromagnetic waves sent by the reader to handle the signals which are to be sent back to the reader. Active ones have sources to supply electricity for the tags and can store extra information from the reader.

Designing and Managing the Supply Chain Study Research 姓名：戴骐倡学号：5090309232 Answer 5:(How would packaging be in the future with the development of RFID?) Firstly,I think packaging with RFID would become more and more popular in the future because it's cheap and convenient. Secondly,I think RFID would be used more in the semi-automatic cases rather than in the full-automatic cases because of the inevitable disturbance from the environment. ● Thirdly,I predict that RFID would be integrated with the technology of Wireless Sensor Network(WSN).WSN is programmable and uses multi-hop communication while RFID is usually not programmable and uses single-hop communication.And RFID integrated with WSN can survive in some of the terrible environments where RFID alone would probably get bad reads.What's more,the sensor-RFID system is likely to be designed to enable USB, Wi-Fi and other communication methods.But unfortunately,this may not be able to generalize in the majority of the supply chains until a feasible way is put forward to cut down the price of WSN.[7] CONCLUSION RFID is a useful technology to packaging of the supply chain.It saves a lot of time and money.By applying RFID with an elaborate design which avoids the obstacles to RF readability, it can achieve marvelous results.And its integration with WSN is also very hopeful.
