Let us take a moment to welcome you to this blog post and share with you some basic information on the concepts of systems analysis and control. The problem: in order to analyze and control a system, it must be defined through defining its boundaries conditions. These are the limits between what is inside the system and what is outside of it. As previously mentioned, these barriers are also referred to as boundary conditions or externalities surrounding the system. There are many types of boundaries one can address when examining how systems will impact individual behavior within them, but there are three particular types that you should focus on when considering the business side of things: environmental boundaries, technological factors, human resources activities that have effects beyond just their employer's company walls. Environmental boundaries have a lot to do with the location of a company and the political environment it operates within. Technological factors refer to the type of technology that is used within a given system, as well as how that technology relates to other variables in play. Human resources activities, such as labor laws and the supply chain management strategy of an organization, also have an effect on business if not properly understood by you as a future analyst or control engineer. Now that we’ve established some basic information on what a system is and how its boundaries can be defined, it seems only right to take a moment and discuss alternate methods for defining these very boundaries – namely, by looking at two additional types of systems – open systems and closed systems. Closed Systems are those that are closed, or bounded by walls. They include your personal car, your house or apartment complex, and many other systems that are closed off to the outside world. Open Systems are those that are open but not necessarily bounded by walls. Waterfalls, for example, tend to be open systems as there is no one outside the system stopping people from getting in to interact with it.When planning how to automate control systems within an organization there are two crucial factors that must be taken into account: the system itself and the human factor associated with it. In order to take a better view of these factors, we must first define the system. The system is defined as any one or more interacting parts that can be measured as a whole. This definition encompasses all manner of systems from basic electricity grids, standard automotive systems, and weather satellites up to entire economies and even cultures. According to biological engineering professor Albert Kalman, an open system is one that consists of a population of interacting elements that may or may not be bounded by physical boundaries. Engineers refer to this as a non-isolated system, meaning that it includes two or more interacting elements that are not separated from each other solely by natural barriers such as oceans or mountains. The idea of a non-isolated system is vital in the overall design and analysis of a control system, as it helps set a context for what a system is in order to make comparisons and predictions. This perspective was once important in the study of systems within factories, but has been largely overlooked by modern control engineers due to advancements in technology. In another works cited from Kalman’s "Biological System" it is said that “Biological systems are open, not because they have doors or windows, but because they consist of elements that interact with each other.” These interactions involve chemical processes happening inside cells which have the effect of influencing the behavior of individual cells and ultimately changing an organism's state. dinamica de sistemas y control eronini pdf download cfa1e77820
