Information Systems for Managing Multiple Small Projects
Published in Richard E. Westney, Computerized Management of Multiple Small Projects, 2017
Operating system: The programming which is built into a computer that enables it to function. The operating system “tells the hardware what to do,” and how to process data with its memory, disks, keyboard, and other devices. The names of many operating systems contain the words “Disk Operating System” (DOS). It also tells the computer how to interface with the various items of software that will be run on it. The operating system is important because it defines the type of software that can be used, as well as the type of programming that can be done.

The Paramics microscopic traffic simulation module can visually simulate the operating conditions of vehicles in a road network, modify the road speed limit in batches, and export data such as the operating vehicle speed and the flow and density of the road. Through the application programing interface (API) of Paramics, this work can find out all the operating conditions of roads in this region and obtain the corresponding operating data. Then, the output data of the Paramics traffic simulation module and the input data of the MOVES pollution calculation module are matched effectively through MATLAB data processing and the transmission module. The data of road number, road flow, average vehicle speed, and road length can be obtained through calculation and integration, and these data can be transmitted to MOVES. Subsequently, MATLAB data processing and the transmission module can be used to call MOVES through the Disk Operating System (DOS) command to batch process the pollution emission calculation.
