Example text

This is one of the reasons why the administration of systems is hard. 3 Controversies and philosophies of science Science and philosophy have long been related. Indeed, what we now call science was once ‘natural philosophy’, or pondering about the natural world. Those who practice science today tend to think little about its larger meaning, or even its methodology. Science has become an ‘industry’—the high ideals that were afforded to it in the seventeenth century have since been submerged in the practicalities of applying it to real problems.

This is because simple systems are easy to understand and their behaviours are easy to predict. We prefer that systems that perform a function do so predictably. Evaluation of individual mechanisms For individual pieces of a system, it is sometimes possible to evaluate the efficiency and correctness of the components. Efficiency is a relative concept and, if used, it must be placed in a context. For example, efficiency of low-level algorithms is conceptually irrelevant to the higher levels of a program, but it might be practically relevant, that is, one must say what is meant by efficiency before quoting results.

We can only do this with a certain measure of uncertainty. To do the best job possible, we need to control those uncertainties. This is the subject of the next chapter. 2 Causality, superposition and dependency In any dynamical system in which several processes can coexist, there are two possible extremes: • Every process is independent of every other. System resources change additively (linearly) in response to new processes. • The addition of each new process affects the behaviour of the others in a non-additive (non-linear) fashion.
