Introduction to Operations Research - Final Snav 1. Currently, State University can store 240 files on hard disk, 320 files in computer memory, and 80 files on tape. Users want to store 200 word-processing files, 280 packaged-program files, and 160 data files. Each month a typical word- processing file a typical packaged-program file, and a typical data file are accessed one times. When a file is accessed, the time it takes for the file to be retrieved depends on the type of file and on the storage medium. If the goal is to minimize the total time per month that users spend accessing their files, formulate a balanced transportation problem that can be used to determine where files should be stored. Use the Nort- West-Corner method to find a initial solution. Use the iterative transportation computation to find an optimal solution and tick the correct option Additional information: Word processing (in minutes) for Hard Disk, Memory, and Tape are 6, 11, and 9, respectively packed program (in minutes) for Hard Disk, Memory and Tape are 13,7 and 5, respectively Data (in minutes) for Hard Disk, Memory, and Tape are 15, 8, and 10, respectively a) NWC solution: $4840 - Optimal solution is $4 520 --- all data files should be stored in Memory b) NWC solution: $4965 and Optimal solution is $4 624 --- all types must be used together to store packaged programs C) None of the above is true NWC solution: $4840 and Optimal solution is $4520-- all word-processing files should be stored in Memory e) NWC solution: $4340 and Optimal solution is $4520--- all word-processing files should be stored in Tape Bo brak
