PROJECTS

Revenue Management System (RMS) United Airlines, Chicago, IL, USA 3 yrs 5 mos

GEMINI is a new revenue management system (RMS) of UAL, developed internally in close partnership with the Continuous Improvement and Enterprise Optimization (CIEO) team. CIEO team formulate algorithms to address those major weaknesses it has in the existing RMS ORION. The simulator-based analysis (both external and internal) shows the improved result that a new system will bring in change an estimated 0.8% to 1% over existing revenue. The RMS is an ecosystem of the collaborating process/projects, below are a few notable projects where I have contributed.

1.Partial-Day-Decrement-Multiplier - Create daily multiplier from input historical booking data based on entity, booking period, days-from-departure (DFD) and passenger time in conjunction with the specified time of the day. This multiplier helps to rectify the RAF2 parameter and creates a more reliable demand.

2.Full-Path-Class-Forecast - The process of adjusting the already evaluated standard demand (remaining adjusted forecast or RAF1) data pool at booking class and itinerary level to a new forecast parameter RAF2, based on various geographical parameters like origin & destination, demand region & demand market; action parameter like booking class, booking period, passenger type; date and time like departure date, connection time, arrival and departure time, etc. The adjustment data are created by the front-end user based situational demand and forecast criteria. RAF1 is received through class partition data and is distributed across several processing nodes and sorted based on previously mentioned class-path criteria, so that comparison could be easy. In case there are matching adjustments found, the process applies it and creates new RAF2 value, otherwise RAF2 will be equal to RAF1. In the end, the process applies decremental logic to further enhance the forecast quality based on entity, booking period, days-from-departure (DFD) and passenger type.

3.Seasonality - Adjust forecast parameter based on a departure date’s seasonal strength. it also adjusts the forecast to correct for time of year booking seasonal bias so that no. Departure dates are impacted by holidays, events, and time of year variances.

4.Significant-O&D - Classify all operating origin and destination (O&D) across entities into large, medium and small markets based on revenue strength using current and historical booking data.

5.Continuous Scaling - When customers are offered dynamic fare instead of regular market fare, booking data needs to integrate the dynamic pricing info at value path level for transparency reason and also for future decisions.

AFLYER — Crew planning system United Airlines, Chicago, IL, USA 4 yrs 6 mos

The primary objective of this application is to create a work schedule for the crew members (mainly FA & pilot) based on available work-hours for a month-to-month basis. The work schedule is further published in a third-party system for preferential bidding. The fundamental input to the system is pairing data, consisting of a series of segments or flight schedules. Pair data is encoded fixed-length record in ASCII format, decoded based on a predefined schema for further processing within the application. The application’s main objective is to filter pairing data according to operational base, date and time, day-of-week (DOW) and many more, then display pairing details, preparing lines by posting them according to predefined scheduling rules and preparing a report based on different criteria. A line is nothing but composed of several pairing with different operational days in a calendar month and positioned accordingly so that it maintains joint rule (workforce union and United airline). It can be prepared in the application either by manual intervention or by using an automatic line generation tool according to the planner’s choice. Finally, all prepared lines are bundled in a flat-file in different encoding formats for exchanging the data with a different system, where it will be published for the bidder.

FastRes - Secure Flight Reservation Channel United Airlines, Chicago, IL, USA 1 yr 6 mos

FastRes is a screen scraping model of the application used as the front-end to the United’s reservation system at the contact center. The system provides menu-driven access to Air ticket reservation with remotely interfaced Apollo system (GDS) for reservation sales. FastRes accepts all mandatory field information from the user and then constructs the appropriate command(s) to interface with Apollo. The Infoconnect Unimatic middleware used as a mediator between the client and the remote host. The response buffer corresponding to the command is received as ASCII data in a fixed-size 2D format, which subsequently parsed to extract the meaningful data for displaying in the GUI. The objective of this application was to facilitate ordinary users to assist in airline ticket booking without knowing any actual command to interact with the Apollo System.

Maersk Automated Rate System (MARS) MSL, Copenhagen, Denmark 3 yrs 4 mos

The Maersk Automated Rate System (MARS) is a suite of applications to store tariff and service contract prices for products and services of the Maersk container businesses. The goal of MARS is to enable complete automation of the application of rates to shipments. MARS is an infrastructure system delivering prices for requests from the customer interfaces based on details of the available products, customer information, cargo characteristics, and optional value-added services. To accomplish this, MARS is divided into three business applications: Tariff, Rules and Service Contract. MARS Tariff holds walk-in rates whereas MARS Service Contract handles all negotiated, customer-specific deviations from Tariff. MARS Rules supports both the Tariff and Service Contract modules with text, data-rich, and calculable surcharge rules. In addition to the Tariff, Service Contract, and Rules, there are two interface applications – Retrieval and Calculator – which hold business logic and handle the input from and output to other customer interfacing systems.

AIO - 4Runner Lexmark International, Lexington, KY, USA 2 yrs 4 mos

All in One (AIO), 4Runner is a Windows-based application and a framework as well. It is developed to adapt and react to the ever-changing printing and printer supplies market. It offers on-demand integration or dis-integration of any application required. It also allows modifying or enhancing the application’s look-n-fill of the user interface.

The framework facilitates the following things

1.Reduce application maintenance through dynamic configuration.

2.Avoid unnecessary re-build by dynamically reconfiguring the application at runtime.

3.Ease of adding or deleting feature/function without impacting the existing function.

4.Localizations efficiencies

5.They support parallel development.

Previously, all existing applications had a high cost of changing UI due to changing code, localization change and little no re-use of code between applications. This new framework has the opportunity to decouple the GUI and make it as lightweight as possible. Any trivial changes to GUI have minimal impact and allow changes to the layout (scriptable) but do not cause a recompile of the code.

Roles/Responsibilities

●Develop different scriptable GUI services based on the proposed design.

●Develop various pluggable GUI elements for the core framework that will be used at runtime.

●Development of discovery service that looks for pluggable services.

●The function definition module has business logic that plugged at runtime.
