DFD Yourdon Recently reviewed In the late 1970s data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system‚ showed how the data moved from one process to another‚ as well as its logical storage. Figure 1 presents an example of a DFD using the Gane and Sarson notation. There are only four symbols: Squares representing external entities‚ which are sources or destinations

SOLUTION TO ANDREW–CARTER‚ INC.‚ CASE This case presents some of the basic concepts of aggregate planning by the transportation method. The case involves solving a rather complex set of transportation problems. Four different configurations of operating plants have to be tested. The solutions‚ although requiring relatively few iterations to optimality‚ involve degeneracy if solved manually. The costs are: [pic] The lowest weekly total cost‚ operating plants 1 and 3 with 2 closed‚ is
