EMS
An energy management system (EMS) is a system of computer-aided tools used by operators of electric utility grids to monitor, control, and optimize the performance of the generation and/or transmission system.Key Benefits
- Monitors and controls generation, transmission and distribution assets in real-time
- Provides real-time situational awareness coupled with advanced visualization capabilities for faster user recognition of the overall system status
- Analyzes near-term operating grid contingencies and provides alternative solutions to reduce potential outages
- Economically provides increased grid capacity while maintaining overall grid reliability and regulatory requirements
- Reduces overall system support costs through intuitive data and display maintenance support tools
- Meets today’s secure system needs with flexible environments including fully redundant primary and backup production, quality assurance, training and development systems
- Increased grid capacity
- Advanced contingency awareness
- Decreased system support costs
- Secure system that meets worldwide regulatory requirements
PMS
Property management systems also known as PMS under business terms may be used in real estate, manufacturing, logistics, intellectual property, government or hospitality accommodation management. They are computerized systems that facilitate the management of properties, personal property, equipment, including maintenance, legalities and personnel all through a single piece of software. They replaced old-fashioned, paper-based methods that tended to be both cumbersome and inefficient.
From http://en.wikipedia.org/wiki/Property_management_system
An efficient property management system will also have features that will assist in analysis, forecasting and control of room rates. This will help the management in ensuring that their rooms are being offered at competitive rates in the market. Further, there will be additional features for the management that will help them make sound business decisions and understand whether they’re able to draw enough revenue from their property. If not, the system should be able to generate reports that can help in taking corrective measures.
Another important feature that any successful property management system should have is – Profile handling. The main purpose of this feature is to keep comprehensive records of all the groups, guests, agents, sources, business accounts and other important contacts of the hotel. Room management is the other feature that keeps track of the housekeeping, maintenance and facility management. The accounting feature in a property management system is generally used for accounting functions like billing, invoicing, bill payments, accounts research etc. The reporting feature is basically meant for generating reports for management, which are then used to take critical business decisions aimed at improving customer satisfaction levels in the hotel.

CAS
A computer algebra system (CAS) is a software program that allows computation over mathematical expressions in a way which is similar to the traditional manual computations of mathematicians and scientists.
Many also include:
- a programming language, allowing users to implement their own algorithms
- arbitrary-precision numeric operations
- exact integer arithmetic and number theory functionality
- Editing of mathematical expressions in two-dimensional form
- plotting graphs and parametric plots of functions in two and three dimensions, and animating them
- drawing charts and diagrams
- APIs for linking it on an external program such as a database, or using in a programming language to use the computer algebra system
- string manipulation such as matching and searching
- add-ons for use in applied mathematics such as physics, bioinformatics, computational chemistry and packages for physical computation
graphic production and editing such as computer generated imagery and signal processing as image processing
sound synthesis
Some computer algebra systems focus on a specific area of application; these are typically developed in academia and are free. They can be inefficient for numeric operations compared to numeric systems.
GDS
A Global Distribution System (GDS) is a network operated by a company that enables automated transactions between third parties and booking agents in order to provide travel-related services to the end consumers. A GDS can link services, rates and bookings consolidating products and services across all three travel sectors: i.e., airline reservations, hotel reservations, car rentals, and activities.
From http://en.wikipedia.org/wiki/Global_Distribution_System
Main Functions:
- Reservations: creating a PNR (Passenger Name Record = booking file containing all relevant reservation data)
- Back-office integrations
- Management Information:
- Yield managmment
- Market Information Data Transfer (MIDT)
CRS
Central reservation system (CRS) is a computerized system that stores and distributes information of a hotel, resort, or other lodging facilities.
A central reservation system is a tool to reach the global distribution system as well as internet distribution systems from one single system. A CRS assists hotel managers in managing their online marketing and sales, allowing them to upload their rates and availabilities to be seen by sales channels that are using the CRS. Sales channels may include conventional travel agencies as well as online travel agencies.
From http://en.wikipedia.org/wiki/Hotel_reservation_system
Primary Functions of CRS
- Intuitive easy to use platform.
- Manage rates, availability, and content from single entry point.
- Connects hotels to GDS, online travel agents, your website and mobile booking engines as well as our call centers.
- Fully scalable as your business and needs grows.
- Easily control property merchandising and packaging.
- Channel manager with central web interface that connects multiple distribution channels.
Detail Management
- Allocate room types, rate plans and close-outs by sales channels.
- Modify room/rate, property and inventory.
- Create new rates, packages and edit content by sales channel.
- Digital media content management tools.
