1. Network Models Lecture 17 (Part l.) The Least Cost Starting Procedure FOMGT 353 Introduction to Management Science

2. The Least Cost Starting Procedure • Starting with the least expensive Flow, we fill in as much flow for that Decision Variable, Xij, as possible. • Adjust the Border Demands and Supplies to take into account the Flow allocated. If there is still a positive amount of Border Demand, goto 3, otherwise stop. • Move to the next least expensive Flow and fill in as much flow for that Decision Variable, Xij, as possible. • Goto 2.
