Contemporary advances in technological know-how and know-how have resulted in a speedy increasein the complexity of such a lot engineered structures. in lots of striking cases,this swap has been a qualitative one instead of simply one in every of magnitude.A new category of advanced Engineered platforms (CES) has emerged as a resultof applied sciences comparable to the net, GPS, instant networking, micro-robotics, MEMS, fiber-optics and nanotechnology. those advanced engineered structures are composed of many heterogeneous subsystems and are characterised through observable advanced behaviors that become because of the nonlinear spatio-temporal interactions one of the subsystems at a number of degrees of association and abstraction. Examples of such structures contain the World-Wide internet, air and flooring site visitors networks, dispensed production environments, and globally allotted offer networks, in addition to new paradigms corresponding to self-organizing sensor networks, self-configuring robots, swarms of self sustaining airplane, shrewdpermanent fabrics and constructions, and self-organizing desktops. figuring out, designing, development and controlling such advanced platforms goes to be a critical problem for engineers within the coming a long time.

Augmentation and parallel operation is the preferred approach. 8 Effective solutions to specific problems cannot be anticipated Specification efforts cannot assume that the most efficient or effective solutions can be anticipated in advance of an exploration and discovery process involving multiple parallel development efforts. 9 Conventional systems engineering should be used for not-to-complex components. Conventional systems engineering is a highly effective discipline when it is used for systems that are not too complex, it provides an important acceleration for the evolutionary engineering process over that of naive evolution where randomness is the only player.

The variety that is the most limiting variety for a hierarchical organization is the variety that has a scale that requires more than one individual to perform a task, but less than that of the system as a whole. It is the existence of large varieties at intermediate scales that are not possible for hierarchical organizations. Either a completely independent or a completely dependent organizational behavior can be readily achieved. We describe the formalism that captures variety at all scales in several steps.

Such behaviors are generally difficult to anticipate and understand. Despite the superficial complexity of the Manhattan and Space Projects, the tasks that they were striving to achieve were relatively simple compared to the problem of air traffic control. To understand complexity of Air Traffic Control (ATC), it is necessary to consider the problem of 3-dimensional trajectory separation --- ensuring that paths of any two planes do not intersect at the same time, considering the many airplanes taking off and landing in a short period of time, and taking into account the remarkably low probability of failure that safety constraints impose.
