MMI was established in and grew through a series of small mergers and acquisitions ultimately earning its name inwhen it took over a major competitor and subsequently broadened its product line. MMI manufactures products that are used as raw materials by large manufacturers and the construction industry and was described as one of the giants in the manufacturing industry with two of its facilities producing basic products with special properties and shapes. However, due to difficulties being faced by the manufacturing industry such as overcapacity, foreign competition and reduced profits; spiralled by a depressed manufacturing economy, the company came under immense financial pressure. Ultimately, the company lost money in two of five years and downsized in which left the remaining workers stretched thin and working at a hectic pace.
Luciano Lavagno and Mihai T. Every day, millions of tons of temperature-sensitive goods are produced, transported, stored or distributed worldwide, thus making their temperature and humidity control essential.
Quality control and monitoring of goods during the cold chain is an increasing concern for producers, suppliers, logistic decision makers and consumers. In this paper we present the results of a combination of RFID and WSN devices in a set of studies performed in three commercial wholesale chambers of m3 with different set points and products.
Up to 90 semi-passive RFID temperature loggers were installed simultaneously together with seven motes, during one week in each chamber.
Thus thank to the feedback of data, between RFID and WSN it is possible to estimate energy consumption in the cold room, water loss from the products and detect any condensation over the stored commodities.
Introduction The production, storage, distribution and transport of cold sensitive products, occurs daily around the world. For all these products the control of temperature is essential [ 1 ].
The inadequate management of this supply chain can reduce the acceptable quality limit of fresh fruit and vegetables FFVs making approximately one-third of these products be thrown away [ 3 ].
Thus, the major challenge is to ensure a continuous cold chain from producer to consumer in order to guarantee the prime condition of goods [ 4 ]. These products may be perishable items like fruit, vegetables, flowers, fish, meat and dairy products or medical products like drugs, blood, vaccines, organs, plasma and tissues.
The properties of all of them are affected by temperature changes. In case of deviations from the optimal cold chain conditions, the shelf life of the sensitive products will be reduced, yet the consequences of this shelf life drop are only physically visible in the advanced stages of the supply chain in many occasions.
To understand this variation is possible by a remote monitoring [ 5 ]. The quality of these products might change rapidly due to inadequate temperature and relative humidity conditions during transport and storage.
Temperature variations can occur during warehousing, handling and transportation.
Inadequate temperature is second on the list of factors causing foodborne illnesses, surpassed only by the presence of initial microflora in foods [ 6 ]. FAO estimates that each year, approximately one-third of all food produced for human consumption in the world is lost or wasted [ 7 ].
Thus, studying and analyzing temperature gradient data inside refrigeration rooms, containers and trucks is a primary concern for the industry.
Any temperature disturbance can undermine the efforts of the whole chain [ 8 ]. It is not easy to maintain appropriate conditions over the whole chain, and negligence or mishandling in the logistics of perishable food products is very common, including goods poorly or excessive cooled.
Jedermann [ 9 ] reported many examples where the inadequate management during temperature control usually leads to losses in the food chain post-harvest, distribution and at home.
Apart from temperature, water loss is one of the main causes of deterioration that reduces the marketability of fresh fruits and vegetables. Transpiration is the loss of moisture from living tissues. Most weight loss of stored fruit is caused by this process.
Relative humidity RHtemperature T of the product, temperature of the surrounding atmosphere, and air velocity all affect the amount of water lost from perishable food products.
Free water or condensation is also a problem as it encourages microbial infection and growth, and it can also reduce the strength of packaging materials [ 1011 ]. Wireless technologies have been considered key technological enablers, whereby intelligent tags are attached to an item, within a network with wireless links, which can transmit some physical parameters such as temperature or humidity in addition with other information like position or movement [ 12 ].
RFID tags are not limited to identification or temperature and RH reading tasks, and recent advancements have produced RFID units able to identify volatile chemicals such as ethylene or ammonia [ 14 ].high performance Radio frequency identification Essay FM Radio And Social Change In Quetta City Sample Essay Benefits of Radio-Frequency Identification (Rfid) .
Use caution if PICO* is near electronic equipment such as RFID (Radio Frequency Identification) readers, anti-theft equipment or metal detectors.
Adverse Effects/Reactions Excessive bleeding is a serious risk associated with the application of suction to wounds which may result in death or serious injury. Radio Frequency Identification (RFID) has been a vital part of the Wal-Mart Corporation's growth.
At the beginning of the s, Wal-Mart trailed K-Mart which at that time could negotiate lower wholesale prices due to its huge size. Department of Homeland Security defines Radio Frequency Identification Device (RFID) as "wireless systems that allow a device to read information contained in a wireless device or "tag" from a distance without making a physical contact or requiring a line of sight between the two.
Benefits of Radio-Frequency Identification (Rfid) Technology on Transpiration Sample Essay Radio-frequency designation (RFID) is germinating into a cardinal technological constituent for many supply ironss and transit.
Radio Frequency Identification has been cited as having a great deal of potential to create value in the supply chain. This 10 page paper is a dissertation proposal to .
