Systems engineering can be an effective tool in the design and operation of organizations to accomplish such urban activities as police scheduling, waste disposal, river purification, fire house location, etc. The relatively unploughed ground of applying systems engineering to the quality of urban life is addressed here. The quality of urban life, an elusive but intuitively satisfying concept, is operationally useful to the extent that a city can identify and move toward achieving the goals of its citizenry. Social indicators measure the extent to which these goals have been achieved. For such indicators to be usable on line inputs for determining changes in urban subsystems, they must respond rapidly and sensitively to the citizenry's changing perception of the gap between goals and actual achievements. Indicators aggregated over long intervals of time, large physical areas, or population groups tend to be sluggish and historical. It is shown how unsolicited complaints and comments from the citizenry may help to define such operationally useful social indicators. A conceptual framework emphasizing adaptive urban subsystems is presented, and data are used to illustrate the feasibility of the approach.","PeriodicalId":120916,"journal":{"name":"IEEE Trans. Syst.

The output concentrations were within 10 percent of the literature data, while the simulated temperature was within 0.5 percent. The simulation is used as an off-line model of the process to design an endpoint control system which makes use of the available feedback from the process. Feedback consists of previously existing instrumentation for effluent gas analysis and an instrument designed for quick carbon analysis. The same instrument, independently conceived by Bethlehem Steel, has been proved effective by them. The control system uses Bayesian inference to evaluate process feedback optimally. Equations have been developed and a computational algorithm designed enabling real-time calculation of the probability of a carbon-temperature state given any control action and imperfect measurements. Because the objective function is almost symmetric and the cost of control is minimal compared to the value of an endpoint state, optimal control drives the expected state vector to the center of the tolerance region.","PeriodicalId":120916,"journal":{"name":"IEEE Trans.

Although it has both off-line and on-line capabilities of application this account is concerned mainly with an explanation of the essentials of the technique in the context of off-line optimization studies. A brief description of a successful application study of a practical problem in industry is also included. The technique is explained in a progressive manner by considering an example for which there is a requirement for an optimum schedule of alternative energy sources. As is well known, optimum scheduling using the dynamic programming technique is restricted in practice by limitations in computer storage and computing time to systems with few independent variables. However, in certain classes of multichannel systems some of these variables appear naturally, or by reasonable approximation can be made to appear, in a static section of the system, and it is shown that optimizing their values need consume only little computer time and storage. The remainder of the variables are in the dynamic section and their optimization makes a heavy demand on computational facilities. The Dynostat technique handles both types of variables in a single computer algorithm. An indication of a projected on-line configuration of Dynostat is presented in a statement of developments of the technique currently under study.","PeriodicalId":120916,"journal":{"name":"IEEE Trans.
