연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

What is claimed is: 1. A transportation state notification system comprising: event detection means for detecting a plurality of types of events relating to lot transportation occurring in a temporary storage devices; storage means for storing lot state data indicating a transportation state of each of the lots; update means for updating the lot state data based on the events detected by the event detection means; and state notification means for displaving an image based on the lot state data, wherein the lot state data includes data indicating an event transition of each of the lots, wherein the state notification means determines whether the lots are in a state of either "under transportation" or "awaiting transportation" based on the data indicating the event transition, and displays an image showing a state of a target lot at a predetermined time as the image showing the transportation load state, wherein the state notification means calculates a transportation load index based on a ratio of a total number of the lots to a number of lots in a state of the "under transportation", and wherein the state notification means displays an image showing the transportation load index as the image showing the transportation load state. 2. A transportation state notification system comprising: event detection means for detecting a plurality of types of events relating to lot transportation occurring in a temporary storage device; storage means for storing lot state data indicating a transportation state of each of the lots; update means for updating the lot state data based on the events detected by the event detection means; and state notification means for displaying an image based on the lot data, wherein the state notification means determines whether the lots are in a state of either "under transportation" or "awaiting transportation" based on the data indicating the event transition, and displays an image showing a state of a target lot at a predetermined time as the image showing the transportation load state, wherein the plurality of types of events include an inter-storage-device transportation event indicating that a lot has been sent from one predetermined temporary storage device to another temporary storage device, a lot arrival event indicating that a lot has arrived at one predetermined temporary storage device from another temporary storage device, a processing device transportation event indicating that a lot has been sent from the temporary storage devices to a processing device of the lots, and a processing completion event indicating that a lot has arrived at the temporary storage device from the processing device, wherein the storage means stores storage state data indicating a lot storage state in the temporary storage devices, wherein the update means updates the storage state data based on the events detected by the event detection means, and wherein the state notification means determines whether the lots are in a state of "under acceptance" indicating that a lot is waiting for the temporary storage devices at a transportation destination to become free, the "under transportation", or the "awaiting transportation" based on the data indicating the event transition and the storage state data, and displays the image showing the transportation load state. 3. The transportation state notification system as defined in claim 1, wherein the storage means stores step data indicating a processing step performed for each of the lots, and wherein the state notification means predicts and notifies the transportation load state based on the step data. 4. An information storage medium storing a program for causing a computer to function as: an event detection section which detects a plurality of types of events relating to lot transportation occurring in a temporary storage device; a storage section which stores lot state data indicating a transportation state of each of the lots; an update section which updates the lot state data based on the events detected by the event detection means; and a state notification section which displays an image based on the lot state data, wherein the lot state data includes data indicating an event transition of each of the lots, wherein the state notification section determines whether the lots are in a state of either "under transportation" or "awaiting transportation" based on the data indicating the event transition, and displays an image showing a state of a target lot at a predetermined time as the image showing the transportation load state, wherein the state notification section calculates a transportation load index based on a ratio of a total number of the lots to a number of lots in a state of the "under transportation", and wherein the state notification section displays an image showing the transportation load index as the image showing the transportation load state. 5. A transportation state notification method, comprising: detecting a plurality of types of events relating to lot transportation in a plurality of temporary storage devices which are provided at different locations, to which lots are transported, and in which the lots are stored; updating lot state data including data indicating an event transition of each of the lots based on the detected events; and determining whether the lots are in a state of "under transportation" or "awaiting transportation" based on the data indicating the event transition, and displaying an image showing a state of a target lot at a predetermined time as an image showing a transportation load state, calculating a transportation load index based on a ratio of a total number of the lots to the number of lots in a state of the "under transportation", and displaying an image showing the transportation load index as the image showing the transportation load state. 6. The transportation state notification method as defined in claim 5, wherein the plurality of types of events include an inter-storage-device transportation event indicating that a lot has been sent from one predetermined temporary storage device to another temporary storage device, a lot arrival event indicating that a lot has arrived at one predetermined temporary storage device from another temporary storage device, a processing device transportation event indicating that a lot has been sent from the temporary storage devices to a processing device of the lots, and a processing completion event indicating that a lot has arrived at the temporary storage device from the processing device, the method comprising: updating storage state data indicating a lot storage state in the temporary storage devices based on the detected events; and determining whether the lots are in a state of "under acceptance" indicating that a lot is waiting for the temporary storage devices at a transportation destination to become free, the "under transportation", or the "awaiting transportation" based on the data indicating the event transition and the storage state data, and displaying the image showing the transportation load state. 7. The transportation state notification method as defined in claim 5, comprising: predicting and notifying the transportation load state based on step data indicating a processing step performed for each of the lots.
