EIQ Analysis Method Analysis of the warehouse management application

Abstract: EIQ analysis as a modern warehouse management in a new way in improving the efficiency of warehouse management, results in significant cost savings from the introduction of EIQ analysis to start to explain the EIQ analysis Application steps, through case analysis presented EIQ Applications.

Keywords: EIQ analysis, system planning, warehouse management

1 Introduction
Storage and logistics functions as one of the two pillars of its efficiency and effectiveness of the overall efficiency of the logistics and cost management have a significant impact as the economy develops, people show more variety of goods demand, the trend of small quantities, storage tasks and time arrangements are increasingly full of uncertainty and dynamic, EIQ analysis is a response to this new situation of a very effective method.

2 EIQ analysis of CLC
EIQ analysis is the authority of logistics experts in Japan, Mr. Suzuki shock through 40 years of practical experience, the original of an analytical method that is called the order number EIQ Entry, Item types and quantities of goods Quantity of significance. Namely the use of E, I, Q of the three key elements of logistics, from customer orders items, the number and order number so starting to study the characteristics of storage demand for warehouses planning basis.

EIQ The basic idea: In order summary Statistics based on the orders of their orders (EQ, the number of items ordered (EN, the number of items (IQ, set by the number of items (IK) and other statistical analysis to obtain planning information.

3 EIQ analysis Application steps
3.1 book to bill of information sampling
Depending on the job cycle and fluctuations to determine the scope of data collection can be daily, weekly or monthly or quarterly for the time range due to the different number of volatile ship warehouses, single-take a 1-day data is not representative, can usual operating experience in a multi-cycle data for selected days compared with each other, and with reference to 1 week or 1 month's data warehouse to determine the different periods in different seasons or changes in the job order to apply in order to adapt to rapid changes in market , EIQ data analysis is generally one month time period.

3.2 orders shipped Statistics
For EQ, EN, IQ, IK four categories of analysis which orders (EQ analysis refers to the analysis of single orders for shipments, the number of items ordered (EN analysis refers to the number of single orders for the goods item analysis, product item number (IQ analysis refers to each one the total number of items shipped analysis; set by the number of items (IK analysis refers to the number of each single analysis of food items shipped.

3.3 Statistics Analysis
Orders (EQ Analysis: Single order to understand the distribution of order quantity, determine the principles of order processing, picking systems planning, impact of shipping methods and shipping area planning. The use of EQ analysis when planning distribution center order picking system , can be used with goods or customer classification of the order ABC analysis to identify important orders and picking the appropriate facilities and equipment to determine when the more obvious trends in the distribution of orders, the district planning principles for the more easy to use, or higher should be flexible equipment based.

Number of items (IQ Analysis: understand the various types of distribution of product shipments, and the importance of analysis of product volume size. Warehouse system planning for use, storage spaces, and the estimated impact of space and picking zone picking methods planning by IQ analysis to understand the amount and distribution of goods shipped, and to analyze the importance of goods and traffic size. warehouse analysis using IQ picking system planning can be classified goods store, the number of commodity stocks According to the size of shipments set a different inventory levels.

Order number of items (EN Analysis: Do not know the order number of items ordered distribution of the principle of order processing, picking systems planning, shipping method and shipping area of ​​planning has great influence, usually with the total of goods items the number of orders of goods and the total number of items items total number of three pointers comprehensive reference by EN analysis, understand the customer's order and distribution of species, so the picking appropriate way to determine a reasonable time and picking picking human needs.

Set by the number of items (IK analysis: analysis of the distribution of the number of products do not ship to find the product other shipping frequency, and with the IQ analysis to determine the warehouse and picking system of choice. In addition, when storing, picking approach has been decided, storage area on the division and configuration storage spaces can also be used as a planning IK results of the analysis reference basis.

4 EIQ analysis Application
The following week in a company warehouse shipping data, for example, the use of EIQ analysis of the warehouse picking system planning, specific shipments of all varieties are as follows
Table 1.

4.1 IQ Analysis and Application
According to the ABC classification method to classify the goods arrive at: I1 and I10 than 20% of the species, the number ratio of 34.87%, identified as Class A products, I6, I8 and I9 of the species ratio of 30%, the number ratio of 30.78 % identified as Class B products, the rest of the species ratio of 50%, the number ratio of 34.44%, identified as Class C products by IQ analysis indicated that the warehouse district classification of goods can be stored to ensure that sufficient Class A stock in trade and fixed storage spaces, large storage area space, storage area location close to shipping port for shipment.

4.2 EQ Analysis and Application
ABC classification method based on the classification table in the order to arrive: E7, E9, E14 and E15 than 25% of orders, the number ratio of 32.35%, identified as A class order, E2, E5, E6, E8 and E16 orders over 31.25%, 33.32% volume ratio, defined as Class B orders, orders for the rest of the ratio of 43.75%, 34.33% volume ratio, defined as Class C orders. By EQ analysis indicated that the warehouse orders can be classified management to ensure that A priority order, the order to ensure the order A fast and accurate transmission of information in order to achieve a reasonable and rapid order division.

Analysis and Application 4.3 EN
To EN analysis, in conjunction with the total number of varieties shipped, shipping varieties of species and total number of total number of three indicators. The warehouse orders for shipping a single number of varieties are larger, and the total number of varieties of goods (10 kinds of small, total number of shipments species (140 species, indicating that the species distribution center repetition rate of orders shipped, can take bulk picking way picking, and according to the size of items to determine the flow characteristics and physical properties when picking or picking post-classification classification practices.

4.4 IK Analysis and Application
IK analysis for analysis, in conjunction with IQ, by calculating the average single order of the number of items (Table 2, and then classified to determine their arrangements and equipment storage spaces.

I1 and I10 of the warehouse shipments and items are the average number of large single orders, picking system planning should be assigned a fixed storage spaces to ensure that high inventory levels, the other in order to ensure their shipments, priority should be to use some advanced equipment . I6, I8 and I9 of the total shipments and the number of items were on average larger single order, the meaning is not obvious for the classification of goods, according to the classification of goods classified as corresponding features in the classification of goods. I4, I5 and I7 of the total of volume and the number of items were on average smaller single orders, distribution flexibility and cargo storage spaces appropriate to adjust the size, usually picking the merger planning and storage area to reduce excess inventory, reduce inventory levels. I2 larger shipments However, smaller single-day shipments, shipments often assigned a fixed storage spaces but sporadic shipping methods to ship and maintain moderate inventory levels, I3 but total shipments of smaller items are the average number of large single orders , flexible allocation of storage spaces, priority mechanization, to ensure a single high volume.

5 Conclusion
EIQ analysis starting from the corporate order, based on customer demand characteristics, combined with the ABC classification of cross-analysis methods, the order of different levels of analysis, the goods in the warehouse receiving, storage, picking, shipping characteristics, properties and provides effective control of logistics entry point for the macro point of the planning process, and ultimately became the decisive factor in warehouse planning and design through EIQ analysis, companies can get a lot of useful information, including: understanding the logistics characteristics, obtained with the properties of the logistics system, logistics system module, select the logistics equipment, simulation, as well as the basis for planning the logistics system.
