Use the information below to answer the following questions.Consider the following maximal flow problem where node 1 is the source and node 6 is the destination. 11ea3b58_9b4d_3337_ba0c_a92ae226e76e_TB1469_00_TB1469_00_TB1469_00_TB1469_00_TB1469_00-Refer to the figure.What is the objective function? October 5, 2022 by 8i9x6 Max X?? Min X?? Max X?? Min X?? Max X?? + X?? See Answer Max X??

Which of the following models determines the path through the network that connects all the points? October 5, 2022 by 8i9x6 Transportation model Assignment model Product mix model Shortest-path model Minimal-spanning tree model See Answer Minimal-spanning tree model

Which of the following is NOT a network flow model? October 5, 2022 by 8i9x6 Transportation model Assignment model Product mix model Shortest-path model Minimal-spanning tree model See Answer Product mix model

A constraint has a slack of 5 units.This implies that: October 5, 2022 by 8i9x6 this constraint has exceeded its minimal requirement by 5 units this constraint has consumed 5 units of its resource this constraint has a surplus of 5 units this constraint is binding this constraint has 5 units of its resource unconsumed See Answer this constraint has 5 units of its resource unconsumed

Assume that the shadow price of a non-binding “?” constraint is 5.This implies that: October 5, 2022 by 8i9x6 if the right-hand side value of the constraint increases by 1 unit,the objective function value will increase by 5 units if the right-hand side value of the constraint increases by 1 unit,the objective function value will decrease by 5 units if the right-hand side value of the constraint increases by 1 unit,the objective function value will remain unchanged if the right-hand side value of the constraint decreases by 1 unit,the objective function value will increase by 5 units if the objective function coefficient increases by 1 unit,the shadow price will increase by 5 units See Answer if the right-hand side value of the constraint increases by 1 unit,the objective function value will remain unchanged

Surplus is typically associated with which type of constraints? October 5, 2022 by 8i9x6 ? ? = ? ± See Answer ?
