(Right Hand Side): Range of feasibility, Dual Value / shadow price, Dual value zero, Dual value negative Dual Value / shadow price: Eg, Interpretation of Dual Prices: (Resource cost is sunk, Resource cost is relevant, Relevant Cost & Sunk Cost) Slack, surplus and Binding constraint: Introduction, Eg-3 Eg-4: Case1: Sensitive Analysis on change in cost vector, Case2: Sensitive Analysis on change in Requirement Vector Timecode: 00:24 range of optimality: 00:34 Change in one decision variable at a time: Eg-1, Eg-2, Q1, Q2 08:58 Change in decision variables simultaneously: Eg-2 Q3 11:29 Sensitive analysis based on change in R.H.S. (Right Hand Side) 12:46 Eg of Dual Value / shadow price 17:28 Slack, surplus and Binding constraint 25:58 Eg-4: Case1: Sensitive Analysis on change in cost vector, Case2: Sensitive Analysis on change in Requirement Vector
