  • Postal code is essential for improving efficiency of mail sorting. The Korean postal code, which is introduced in 1970 and had been reformed two times, has controversial issues because of changed postal environments such as modification of administrative districts and logistical transformation into a hub-and-spokes structure. In this study, we propose several improvement and evaluation methods in order to prepare an alternative plan of postal code system. After performing status analysis, we define the customers of postal code and analyze the requirements of them. The 6 proposed new postal code systems are based on each customer groups’ requirements. To evaluate the new systems, we develop several quantitative and qualitative indexes and make a survey of postal experts. Besides, we evaluate the influence of them to the postal environments including delivery sequence sorting process.

  • Recently many efforts on the development of automatic processing system for delivery sequence sorting have been performed in ETRI, which requires the use of postal 4 state bar code system to encode delivery points. This paper addresses the issue on the reduction of reading error in postal 4 state raster beam based bar code reader by adjusting measured values of bar code width to its average value over each interval. The test results show that the above method reduces the average reading error rate approximately by 90-100%.

  • In most mail automatic processing centers, after facing and canceling, letter mails are passed through an Optical Character Recognition/Barcode Sorter(OCR/BS) to read the postal code and 3 of 5 fluorescent (luminescent) barcode is applied. Normally, 31%∼35% of this mails are rejected. The main reasons for reading failures are poor printing quality of addresses and barcodes, script printing, writing in a cursive hand, variety fonts, and failure to locate the address. Our goal is to provide mailer with top quality service and customer barcode service as we move toward 100% barcoding automation of letter mail. In this paper, we propose a method of printing 3 of 5 customer barcode, postal code management, and detection of postal code based on postal address for increase the performance of automatic processing system in mail items. Using postal code generating rules, which are automatically extracted from postal addresses and address numbers, creates postal codes. The customer barcode support system is implemented by C++ language and runs on IBM PC under Windows 95.

  • In this paper, we describe the system to recognize the six digit postal number of mails using neural network. Our zip-code recognition system consists of a preprocessing procedure for the original captured image, a segmentation procedure for separating an address block area with a shape, and recognition procedure for the cognition of a postal number. we extract the feature vectors that are the input of a neural network for the recognition process based on an area optimizing and an image thinning processing. The neural network classifies the zip-code in the mail and the recognized zip-code is verified through the zip-code database.

  • Recently many efforts on the development of automatic processing system for delivery sequence sorting have been performed in ETRI, which requires the use of postal4-state bar code system to encode delivery points. The 4-state bar code called postal 4-state barcode for high speed processing that has been specifically designed for information processing of logistics and automatic processing of he mail items. The Information of 4-state bar code indicates mail data such as post code, delivery sequence number, error correction code worked, customer information, and a unique ID. This appear addresses the issue on he reduction of reading error in postal 4-state raster beam based bar code reader. The raster beam scanning features are the unequally distributed number of spots per each unit, which cause reading errors. We propose a method for reducing the bar code reading error by adjusting measured values of bar code width to its average value over each interval. The test results show that the above method reduces the average reading error rate approximately by 99.88%.

  • A systematic approach for interpreting Korean addresses based on postal code is presented in this paper. The implementation is focused on producing the final delivery point code from various types of address recognized. There are two stages in the address interpretation : 1) agreement verification between the recognized postal code and upper part of the address and 2) analysis of lower part of the address. In the agreement verification procedure, the recognized postal code is used as the key to the address dictionary and each of the retrieved addresses is compared with the words in the recognized address. As the result, the boundary between the upper part and the lower part is located. The confusion matrix, which is introduced to correct possible mis-recognized characters, is applied to improve the performance of the process. In the procedure for interpreting the lower part address, a delivery code is assigned using the house number and/or the building name. Several rules for the interpretation have been developed based on the real addresses collected. Experiments have been performed to evaluate the proposed approach using addresses collected from Kwangju and Pusan areas.

  • In this paper, we proposed the automatic postal drop-off system based on the microprocessor board or PC. The weight of the small postal package is transmitted from the electronic scale and user-entered addresses and delivery rate are processed by the controller to calculate the fee. For 24 hour out-door operation and maintenance, non-cash payment methods such as credit card payment is used. The post stamp and receipt are printed by the thermal printer. For the electronic processing of the parcel, serial code is also printed on the stamp and receipts in bar code format. The parcel information obtained by the automatic postal drop-off system is transferred to remote central system by dial-up modem shared by the on site office. The proposed system and its control software are built for prototype model operation and the result met the design requirements. For real time processing, data reception through three serial ports is handled by interrupt routine. The proposed system is expected to be applied for commercial logistics system and pc automation system.

  • 우편물량 처리에서 병목현상의 원인이 되고있는 수작업에 의한 순로구분 작업을 원활하고 신속하게 처리하며 집배원의 업무 부담을 경감시키기 위해 자동화가 시도되고 있다. 이러한 자동화된 순로구분기의 개발에 있어 순로구분에 필요한 주소 데이터 베이스를 관리하기 위해서는 각 배달지점에 대한 고유한 ID 부여가 필요하다. 따라서 본 논문에서는 아직 체계화되지 않은 한국 주소의 배달점 코드 설계 방안에 대해서 연구하였다. 먼저 해외 각국의 배달점 코드할당 방법을 알아보고, 배달점 코드의 기본 정의 및 설계 방향을 제시한다. 그리고 각 주소의 고유한 배달점 코드를 설계하는데 있어 여러 가지 방안을 제시하고 각 대안별 장단점 및 설계 방법을 제시하였으며 적합한 설계 방안을 선정하였다. 또한 기존의 주소체계뿐만 아니라 도입 예정인 새주소 체계와의 적합성도 고려하였다. 본 논문에서 제시한 우편번호 앞 3자리와 6자리의 일련번호를 연결한 배달점 코드가 현재의 한국 주소체계 뿐만 아니라 새주소 체계에도 적합할 것으로 판단된다. 마지막으로 몇 가지 적용 사례를 통한 제안한 방안들을 검증해 보았다.
