• Focus on passengers’ diversified, personalized, one-stop integrated

service needs.

• Based on core service such as ticket service, provide journey planning

services, and multi-channels booking, variety of payment methods and

multiple ticket types.

Passenger Service

• Support ticket delivery, catering, hotels, tourism, car rental and other

extension booking services.

(6)

• To maximize the revenue of transport enterprises with deploying CRM

system.

• Carry out railway VIP plan, build customer points reward system to

attract and stable customer resources, enhance the overall

competitiveness of the railway.

Marketing

6 Jiansheng, Zhu

• To improve the level of marketing decision support and give

reasonable suggestions of capacity adjustment, concessionary fares

and ticket organization strategy.

(7)

Business Requirement

• To innovate ticketing organization with the change from the original

accurate inventory management(AIM) to a combination of AIM and

quantity management.

• To promote the management level of ticketing organization from

traditional manual into intelligent and automated management.

Operations Management

• To strengthen ticketing business monitoring for fair ticketing, from

decentralized management into a combination of centralized and

decentralized management.

(8)

ticket processing time < 1.5s.

• Peak hour tickets amount takes 15% of whole.

Performance Requirement

8 Jiansheng, Zhu

• The quantity of query is 100 times of transaction.

• Ticket checking time in Gate < 1.2S.

Technical Solution

The NG-TRS Architecture

• The existing TRS’ inventory and core data are physically located in each regional data center. During the operating practices, there’re existing longer system operation and maintenance chain, higher construction costs of

security systems, more difficult in data synchronization and application software upgrades.

• The New Generation TRS will adopt a centralized architecture, the inventory

• The New Generation TRS will adopt a centralized architecture, the inventory of whole country and associated core transactions will be centralized. After the inventory is centralized, the NG-TRS will establish the architecture of three centers in two places, include the 1st Data Center in MOR, the 2nd Data center in the same city and a Disaster Recovery Center in another city (>1000KM).

Technical Solution

The NG-TRS Architecture Design Concept

• The 1st _{and 2}nd _{data center is dual-online and backup by each other}

- The 1st and 2nd DC store all inventory of whole country.

- Adopt the bi-directional database replication technology.

- Switching time will be 5-10 minutes for dual-online business and 15-30 minutes for backup business.

- Connected by 10G fabric network.

• Disaster Recovery Center to take over the business-critical

- Two DCs backup core business data to DRC by OS level backup technology in near real time.

(12)

Technical Solution

The NG-TRS Architecture Design Concept

• Bureaus set up the Business Front-end

- All bureaus set up Bureau Business Front-end(BBF) system to carry telephone booking, AFC, accounting, bureau-level marketing, bureau-level CRM, data interfaces and some bureau personalized services.

- The BBFs are connected to the 1st, 2nd DC and DRC by 155M WAN.

• All stations DO NOT set up ticket server

- The stations only set up the station-level AFC emergency equipment, terminals and equipment of the station-related business direct access to BBF.

- Stations are connected to BBFs with dedicated line speeds from 2M to 1G.

Technical Solution

The Cloud Computing Environment in DCs

• The NG-TRS uses open system architecture, two DCs and DRC design

several business partitions to host different business.

• Business partitions are accessed through the service interfaces in TSIP, and the capacity of each partition can be separately extended.

the capacity of each partition can be separately extended.

Technical Solution

The Inventory Cloud

• The minimum slice of inventory data is single train, that is stored and processed according to the origin of train;

• TO deploy Inventory Processing Unit(IPU) to handle inventory management

and ticket transactions, one IPU equals one Inventory Cloud Node(ICN), every ICN can carry multiple trains’ inventory, and whole ICNs form

Inventory Cloud.

• Inventory data of single train can be immigrated from one heavy load node

• Inventory data of single train can be immigrated from one heavy load node to another light one.

• The inventory processing capacity can be extended through increasing the

number of ICN. During the ticketing peak time such as Chinese Spring Festival, we can online more ICNs to improve the overall processing capacity, and surplus processing capacity can be used for business of statistical analysis in the trough.

• TSIP is in charge of the load distribution and trading navigation of ICNs.
