The result by using CIM and RFID system in Taipei flora exposition

In such a special period and environment condition, how to maintain the quality of the exposition will be a big challenge. The authority has to replace withered flowers by fresh ones. Two major challenges are faced by the authority while counting flora products. The first consideration is how to use less labors to get all flowers data within the shortest path, and the other one is how to reduce counting time. Labors, for serving in Taipei Flora Exposition, need to count of every flower manually. It means that we have to walk every route for every flower and need a lot of papers works to check the flowers life cycle, replacement date, planted date, and etc. These paper works not only need a lot of labors to deal with but also take a lot of time to process these data. What`s worse, we will waste a lot of time to walk every route for counting.

These problems will increase our labors cost and time cost greatly in this case.

Therefore, we will implement CIM system into this case.

At the beginning of applying this technology into this case, we need to divide all flowers into different areas, different blocks, and different batches in order. After clustering flowers, we will embed RFID tag into every batch of flowers with name data, life cycle data, region data and etc.

For the CIM system used in Taipei Flora Exposition, we use cloud database to integrate current data. When inventory personnel count, they use handheld reader to check, revise, and confirm the amount of flowers after connecting with the end users in the cloud. With the integration of cloud computing database, rear end users can easily get the amount of flowers and RFID tags. Preparation for the system is to collect data for different flowers into RFID tags, classify flowers, and input in electronic database for integration when flower and RFID tags suppliers transport products to warehouse.

Before we apply cloud inventory management system into this case, labors, for serving in Taipei Flora Exposition, need to count of every flower manually. It means that we need a lot of paper work to check the flowers life cycle, replacement date, planted date, and etc. These paper works not only need a lot of labor to deal with but also take a lot of time to process these data. Therefore, our cloud inventory management system can help us to improve this issue.

At first, we will choose a block of flowers which has been embedded with RFID tags. With the handheld wireless RFID reader to do inventory management, we can get the data from the tags which were embedded inside after scanning this area. For example, we can get the data, including the name, life cycle, and amount of flowers. If we need to update or exchange the data, we can process synchronously via the rear-end cloud database service to inquire the stocking of flowers, or economic order quantity of flowers so that the concurrent engineering will be implemented to update and exchange the data simultaneously. If we do not have to update or exchange the data, we can make a record on the tags which were embedded in flowers so that it will help improve the effectiveness and efficiency of taking stock.

For this exposition, we will consider environment limitation as the following statements for our model assumption:

1. With the wide hinterland in this exposition, we need lots of labors to check stock for every batch of flower.

2. With the significant amount of flowers, it takes lots of labor cost and time to do inventory management.

3. With different life cycle for different flowers, it takes lots of time and labor cost to manage and integrate information.

21

4. There are no path obstacles in this case.

5. Every route is smooth without altitude.

6. Operators work 8 hours every day.

7. Operators have same walk speed in this case.

8. Operators take 10 minutes break after 50 minutes work.

9. Operators need to count every batch of flowers one by one.

In the process of counting in Taipei Flora Exposition, flower supplier and tag supplier will keep products into warehouse. In the warehouse, flowers will be categorized and tags will be embedded with flower information so that the CIM system can integrate these information. When labors check stocks with RFID handheld reader, we can use the user platform, which is installed in handheld reader, to link the rear end clouding computing system. For instance, we find out the amount of flowers is under the safety stock, we can choose “place an order” to order flowers by labors. These actions will be recorded in CIM system for checking and updating simultaneously.

In this case, we divide Taipei Flora Exposition where planted with flower into 4 area and measure the route length and working time. In the table shows the route length comparison between each other, and the working time comparison between each other.

(1) By using cloud inventory management system, we can easily find out the reduction of route length and time reduction. As we can see from the table, by using the efficiency formula (see Eq. 1), we can acquire the data for the improvement of working efficiency. In the same route, we use less time to finish flowers checking and data processing.

This system provide us a simultaneously interaction between labor and their work. This system helps us to shorten 82.9792% walking route and time requirement to do flowers inventory counting. After applying the cloud inventory management system based on RFID technology, the efficiency of inventory counting gets greatly improved. According to the table, the inventory counting route lengths have been reduced 510563.7 meters after applying cloud inventory management system and inventory counting time reduced 9209.994 minutes after applying CIM system. The

labor cost reduced and the inventory management information is advanced processed.

In addition, the improved square measurement only has 17.044%. It indicates that applying cloud inventory management system has significantly improvement on working efficiency and time reduction in this case.

In this special case, we have special environmental limitation, including huge counting area. As a result, our efficiency improves dramatically by implementing cloud inventory management system base on RFID. RFID technology plays a very important role in the process to achieve rapid, real-time, standardize of collecting and processing of the logistics system. From the result we learn from the table, we have 82.955% efficiency improvement about route length and time reduction. In this special case, we actually lower down labor cost and time cost dramatically.
