of the port. This meant that for each route‚ each price or quantity was subject to an individual constraint‚ and all the other ten routes were not tied to each other in any way. the new pricing model proposed‚ takes into consideration that there is no individual constraints but rather an overall constraint which is the weight and volume of the ship travelling those routes‚ so within those constraints what dictates price is the demand. It was clearly stated that 40’ containers were not only preferred

minimized‚ and a set of constraints that circumscribe the decision variables. In the case of a linear program (LP) the objective function and constraints are all linear functions of the decision variables. At first glance these restrictions would seem to limit the scope of the LP model‚ but this is hardly the case. Because of its simplicity‚ software has been developed that is capable of solving problems containing millions of variables and tens of thousands of constraints. Why is “rounding-down”

goals are to expand the campus to accommodate local population growth. In the expansion we have to accommodate on and off campus classes via online capability as well due to the increase in enrollment. 2. What are the business constraints? (10 points) The constraint is dividing the funding. Because of how the funding is gathered‚ it must be spent in a responsible way. Since funding is obtained through property taxes and bonds. 3.

Clay Shirky opens up his TED talk with a true story about Kenya‚ and some of its citizens. During 2007 there was a dispute with the presidential election and ethnic violence broke out in the country. Quickly following there was a media blackout‚ during which a lawyer in Nairobi was chronicling the events in a blog. As she was tracking the violence and keeping others informed the comments began to streamline and if they contained pertinent information‚ she would collate them and re-post them for
