Human-machine interface

The design of human machine interfaces for the use of computer and information systems is still more of an art form than a science. Because humans are so adaptable that they can cope with awidw range of a situations, there has not been asmuch experimentation on and evaluation of interfaces as might be expected. Most of this generation`s designer of terminals and software interfaces were trained when computer hardwere was expensive relative to people costs. Many user communities represented captive audiences, such as employees who had to use whatever system was provided. As a result, human factors and optimization of the human interface were often sacricificed for machine efficiency.

Weighted failure rate

All the failure rates associated with a system are collected. These are then weighted, depending on the deviation from the system being assessed and other factors thought to be significant. A best estimate is then produced by combining all the available information and applying expert judgement. A good example of this is the failure rates used within the HSE risk assessment tool RISKAT. The pipework failure frequency was derived by a review of 22 references.

Discounted cash flow

As discussed earlier, the income approach is based on the concept that the value of an asset today represents its expected future benefits discounted to a present value. Victoria uses the discounted cash flow (DCF) methodology in her analysis. This method forecasts Acme`s cash flows for several years -often five years-- into the future and discounts them to a present value. In addition, this method assumes that Acme will be sold at some point in the future and the owner will receive sales proceeds at that time.

Distributed control systems

Idea of networked software agents is particularly popular in the field of information sciences dealing with distributed content, whereas in industrial automation its use is usually limited to manufacturing system. This work presente a concept of multiagent networking system for automation of continuous processes. Some properties of typical software agent had to be dropped in exchange for determinism and satisfying time performance in negotiations between network-connected control components. The proposed environment is National Instrument LabVIEW, very popular solutıon for automation and measurement. LabVIEW is equipped with advanced data acquisition tools and is capable of artificial intelligence methods, although it lacks agentification mechanisms.A framework is presented, providing LabVIEW the required functionality.
