On Friday, April 13, Krampf had empty cars at the following towns in the quantities indicated. Minimizing total miles over which cars are moved to new locations, compute the best shipment of coal cars. Use the northwest corner rule MODI method. Factory availabilities, projected store demands, and unit shipping costs are summarized in the table that follows. George Monohan, president of Monohan Machinery, is convinced that harvesting weeds is far better than using chemicals to kill weeds.
Chemicals cause pollution, and the weeds seem to grow faster after chemicals have been used.
George is contemplating the construction of a machine that would harvest weeds on narrow rivers and waterways. The activities that are necessary to build one of these experimental weed-harvesting machines are listed in the accompanying table. Construct a network for these activities. F After consulting with Butch Radner, George Monohan was able to determine the activity times for constructing the weed-harvesting machine to be used on narrow rivers. George would like to determine ES, EF, LS, LF, and slack for each activity.
