two questions about transportation and transhipment problem

this is two questions about transportation and transhipment problem

the first question about transportation problem and the second about transhipment problem


question1 :

Powerco has three electric power plants that supply the needs of four cities. Each power plant can supply some number of killowatt-hours (kwh) (see table). The peak power demands are also given in the table, as are the costs of sending 1 million kwh of electricity from a palnt to a city. Formulate a LP to minimize the cost of meeting each city's peak power demand.

question2 :

Widgetco manufactures widgets at two factories, one in Memphis and one inf Denver. The Memphis factory can produce up to 150 widgets per day, and the Denver factory can produce up to 200 widgets per day. Widgets are shipped by air to customers in Los Angeles and Boston. The customers in each city require 130 widgets per day. Because of the deregulation of air fares., Widgetco believes that it may be cheaper to first fly some widgets to New York or Chicago and then fly them to their final destinations. The costs of flying a widget are shown below. Widgetco wants to minimize the total cost of shipping the required widgets to its customers.
