Systems science is an transdisciplinary[1] field that studies the nature of systems—from simple to complex—in nature, society, cognition, engineering, technology and science itself. To systems scientists, the world can be understood as a system of systems. The field aims to develop interdisciplinary foundations that are applicable in a variety of areas, such as psychology, biology, medicine, communication, business management, engineering, and social sciences.
Systems science covers formal sciences such as complex systems, cybernetics, dynamical systems theory, information theory, linguistics or systems theory. It has applications in the field of the natural and social sciences and engineering, such as control theory, operations research, social systems theory, systems biology, system dynamics, human factors, systems ecology, systems engineering and systems psychology. Themes commonly stressed in system science are (a) holistic view, (b) interaction between a system and its embedding environment, and (c) complex (often subtle) trajectories of dynamic behavior that sometimes are stable (and thus reinforcing), while at various 'boundary conditions' can become wildly unstable (and thus destructive). Concerns about Earth-scale biosphere/geosphere dynamics is an example of the nature of problems to which systems science seeks to contribute meaningful insights.

The Manila Metro Rail Transit System (MRTS), commonly known as the MRT, is a rapid transit system that primarily serves Metro Manila, Philippines. Along with the Manila Light Rail Transit System and the Metro Commuter Line of the Philippine National Railways, the system makes up Metro Manila's rail infrastructure.
The MRT's 16.9-kilometer-route consists of 1 line and 13 stations (in operation). The first and the only line currently in operation, MRT Line 3 is jointly operated by the Metro Rail Transit Corporation, a privately owned company, and the Department of Transportation (DOTr) through a Build-Lease-Transfer agreement. Line 3 was opened in December 1999 and completed in July 2000. (Full article...)

The Work Breakdown Structure (WBS) is a means of organizing system development activities based on system and product decompositions. The systems engineering process produces system and product descriptions. These product architectures, together with associated services (e.g., program management, systems engineering, etc.) are organized and depicted in a hierarchical tree-like structure that is the WBS.

Selected biography -
Herman Kahn (February 15, 1922 – July 7, 1983) was an American physicist and a founding member of the Hudson Institute, regarded as one of the preeminent futurists of the latter part of the twentieth century. He originally came to prominence as a military strategist and systems theorist while employed at the RAND Corporation. He analyzed the likely consequences of nuclear war and recommended ways to improve survivability during the Cold War. Kahn posited the idea of a "winnable" nuclear exchange in his 1960 book On Thermonuclear War for which he was one of the historical inspirations for the title character of Stanley Kubrick's classic black comedy film satire Dr. Strangelove. In his commentary for Fail Safe, director Sidney Lumet remarked that the Professor Groeteschele character is also based on Herman Kahn. Kahn's theories contributed to the development of the nuclear strategy of the United States. (Full article...)
