Horizon High Performance Expert System “Shell” SAFENA - is now being used in innumerable practical applications such as Medicine, Law, Insurance, Education, Finance and Marketing. Its main uses are for the purpose of knowledge representation, decision making, supervision, diagnosis, productivity-enhancement, inferencing and command and control.

The simplicity of the system is its unique feature; it is designed to be operational within a matter of minutes and needs no computer expertise to use this system. Safena can cater for an almost unlimited number of rules, restricted only by the storage space of your computer. These rules are based on ”IF”……..”THEN" statements, whose inter-connective logic will chart the course of reasoning or inferencing through selected sequences of evaluation, culminating in a conclusive solution of the "unknown" from accumulated wisdom of the "known".

An almost unlimited number of rules can be entered in any order and, since the inferencing mechanism will determine the order in which they are "fired", you are free to design the system with complete flexibility.

Why is it called SAFENA?

S~tructured knowledge base of thousands of rules
Safena is designed to be operational in a matter of minutes, yet you do not need to be a computer expert to build and run the knowledge-based systems. It can incorporate thousands of rules with absolutely no degradation in performance.

A~dvanced artificial intelligence programming techniques maximise capability
Safena uses advanced programming techniques throughout the system. Irrespective of the complexity of the processing required, operator tasks are only minimal. The system is self-checking, with in-built security.

F~lexible, high performance rule-based expert system
Safena is a high performance rule-based expert system shell which can be used in any area, such as problem domains, diagnoses, and real-time command and control.

E~xtendable to an infinite degree of complexity
Safena knowledge base is not fixed and so is totally re-useable; rules can be added, changed or linked without recompiling the system. It makes no heavy demands on computing power and memory.

N~eural designs and unlimited interconnectivity
Safena could not be simpler to use. Based on a neural design offering almost unlimited interconnectivity, Safena simply passes a parameter to or from the required processing point. Entry is in the easy Question…Answer…Action format, so with the right parameters, a robot could be made to catch a ball!

A~rtificially high expectations have become a reality
The advent of the so-called fifth Generation of computing has created high expectations of a degree of processing power and speed, which up to now has been the privilege of very advanced and expensive computers frames. This is now available through Safena for performing highly complex tasks. Almost unlimited numbers of rules can be entered in any order, since the inferencing mechanism will determine the order in which they are executed and thus the user is free to design multiple Knowledge Bases with confidence.

Safena in Use

Medical
In the medical environment it is being used by doctors, nurses, primary health care managers and administrators. It assists in the running of many aspects of a busy general practice or hospital for clinical data analysis and decision making.

SAFENA will perform different functions when used in the office of the health care manager or administrator. For instance, during a normal dialogue with SAFENA if a health manager indicates that there is cold weather, the system will react to this The SAFENA inferencing mechanism, through natural sequence of evaluations, will remind the health manager about all those patients suffering from heart and lung disease, who have not had certain due treatment (such as an influenza jab) and are more vulnerable to such harsh weather conditions. SAFENA will also seek the permission of an administrator to automatically activate recall procedures to patients needing attention in such situations.

Unfriendly Environments
SAFENA is already used within the field of stock control and enquiry systems. The system helps provide a more relevant search pattern for customers when they make an uncertain request for a part. Not only does it provide information on that particular item, but also provides an insight into alternatives. In the case of the motor trade this service does away with the need for a person to be an expert in every car ever built and its relationship to parts of all other cars.

The system is also in use on the factory floor. Here, for example, there is the problem of the machine operators knowing the details of the current products they are producing as well as those of other runs. The ability to relate tooling from one job to another is a very cost related factor on a production run. With SAFENA this information is collated and provided whenever needed without the need for input from the Toolmaker who would normally have to supply this valuable information. This use of products to enhance the services of a business such as oil exploration is being further enhanced by the addition of an independent voice input. This results in the elimination of the need for a mechanical input device. The system can therefore be quickly and easily adopted for use by unskilled operatives.

Objects concept in SAFENA.



Safena communicates with objects. There are 1 to 8 objects. Each one can act as :

an operator
a file or a point of delivery
a reference point
a router for data flow directions to the serial communications for digital to analogue conversion
an interface to data acquisition or display.

Clicking the required object will activate that object and now all the action parameter values are directed to the selected object.

For example in the computer hardware support environment, object-1 or operator-1 is responsible for changing the hardware and Object-2 or operator-2 is responsible for checking for viruses. When the action requires a change of hard disk the action command "change hard disk" is directed to object-1 and when it is necessary to check for viruses the action command "Chkv.exe" is passed to object-2. In this way you can pass a computer command to run a program or an instruction to be carried out by human being. In the example of a power station these different objects can be used to pass information to the coal feeders and air vents.

Another example in the Tele-medicine environment would be when you have told your doctor about your symptoms. SAFENA will instruct the nurse to perform blood tests, a technician to do an ECG, a secretary to refer you to the specialist, a transport administrator to arrange for an air ambulance, paramedics to collect you from the airport and the ward administrator to arrange for your bed.
