The model can be solved using branch and bound method (branch and bound).
Herein it should be noted that branch and bound method is a kind of search for solving the non-solution of exclusion of combinatorial optimization problem
Algorithm, when solution space is searched for, conventional tree structure organizes solution space.It is that the one kind for solving integer programming problem has efficacious prescriptions
Method, can both solve pure integer programming problem, and mixed integer programming problem can be solved again.The basic thought of branch and bound method is
Implicit enumeration, i.e., enumerate feasible combination.It is, from corresponding optimal solution, to ask original if being not integer if this solution
Topic resolves into two parts, per new constraint is partly increased, compresses feasible zone, the optimal integer solution of Step wise approximation.
This thinking be mainly based upon it is following three aspect the fact and set up：
1) if what is obtained during the relaxation problem of one integer programming of solution is an integer solution, this solution also must be
The optimal solution of integer programming.
If 2) what relaxation problem was obtained is not an integer solution, optimal integer solution will not necessarily be better than resulting
The desired value of relaxation problem, therefore, the solution of linear programming relaxation problem must be a boundary of integer programming target function value.It is right
It is the upper bound in maximization problems, is lower bound for minimization problem.
If 3) oneself will not necessarily be inferior to the integer through obtaining an integer solution, optimal integer solution during solution
Solution.Therefore, the integer solution may make up another boundary of optimal integer solution, and it is lower bound for maximization problems, for minimizing
Problem is the upper bound.
Branch-and-bound tree is called Enumeration Tree, and it embodies famous divide-and-conquer strategy, even directly on former solution space
Solve problems are too difficult, then whole solution spaces can be repeatedly divided into less and less subset, by these compared with
Small collection is closed optimizing, and then acquired results are compared the optimal solution for finally trying to achieve former problem, branch-and-bound tree such as Fig. 2 institutes
Show.
Commonly referred to as S0It is S1…SNFather node, and S1…SNReferred to as S0Child node.Therefore, given node is all
Child node means that the division to their father node feasible zones.And it is called branch to the line of another node from a node.
The flow of branch and bound method can be summarized as follows：
Step 1：Initialization, arbitrarily large value is assigned to former problem supremum, iterations initial value layer=1 and most
Big iterations layerMax.
Step 2：Solve the corresponding relaxation problem of former problem.Judge whether former relaxation problem is feasible, if without feasible solution, it is former
Problem is without solution；It is former Optimum Solution if finding the optimal solution for meeting integer requirement；If unmet integer requirement is most
Excellent solution, then in adding it to treat branch problem queue P.And the desired value of former relaxation problem is set under the minimum of former problem
Boundary.
WHILE(layer≤layerMax)DO
Step 3：Judgement treats whether branch queue P is empty.It is to jump out major cycle, from integer feasible solution, finds out former problem
Optimal solution；Otherwise perform step 4.
Step 4：Choose lax subproblem successively from branch's queue is treated and carry out branch's solution according to branch's principle, and
It is deleted from P, treats that a branch updates the minimum Lower and upper bounds of former problem after finishing, while obtaining the branch next time
Father's problem matrix P.
Step 5：According to branch principle is cut, father's problem matrix P is updated.
Step 6：Layer=layer+1.
END DO

Module is solved, for solving Power Material allotment model using branch and bound method, at least one target deposit is obtained
The deployment information of the emergency electric power goods and materials of point and each target deposit point.
In a kind of optional scheme, because Power Material allotment model is a typical integer programming model, therefore,
The model can be solved using branch and bound method (branch and bound).
Herein it should be noted that branch and bound method is a kind of search for solving the non-solution of exclusion of combinatorial optimization problem
Algorithm, when solution space is searched for, conventional tree structure organizes solution space.It is that the one kind for solving integer programming problem has efficacious prescriptions
Method, can both solve pure integer programming problem, and mixed integer programming problem can be solved again.The basic thought of branch and bound method is
Implicit enumeration, i.e., enumerate feasible combination.It is, from corresponding optimal solution, to ask original if being not integer if this solution
Topic resolves into two parts, per new constraint is partly increased, compresses feasible zone, the optimal integer solution of Step wise approximation.
This thinking be mainly based upon it is following three aspect the fact and set up：
1) if what is obtained during the relaxation problem of one integer programming of solution is an integer solution, this solution also must be
The optimal solution of integer programming.
If 2) what relaxation problem was obtained is not an integer solution, optimal integer solution will not necessarily be better than resulting
The desired value of relaxation problem, therefore, the solution of linear programming relaxation problem must be a boundary of integer programming target function value.It is right
It is the upper bound in maximization problems, is lower bound for minimization problem.
If 3) oneself will not necessarily be inferior to the integer through obtaining an integer solution, optimal integer solution during solution
Solution.Therefore, the integer solution may make up another boundary of optimal integer solution, and it is lower bound for maximization problems, for minimizing
Problem is the upper bound.
Branch-and-bound tree is called Enumeration Tree, and it embodies famous divide-and-conquer strategy, even directly on former solution space
Solve problems are too difficult, then whole solution spaces can be repeatedly divided into less and less subset, by these compared with
Small collection is closed optimizing, and then acquired results are compared the optimal solution for finally trying to achieve former problem, branch-and-bound tree such as Fig. 2 institutes
Show.
Commonly referred to as S0It is S1…SNFather node, and S1…SNReferred to as S0Child node.Therefore, given node is all
Child node means that the division to their father node feasible zones.And it is called branch to the line of another node from a node.
The flow of branch and bound method can be summarized as follows：
Step 1：Initialization, arbitrarily large value is assigned to former problem supremum, iterations initial value layer=1 and most
Big iterations layerMax.
Step 2：Solve the corresponding relaxation problem of former problem.Judge whether former relaxation problem is feasible, if without feasible solution, it is former
Problem is without solution；It is former Optimum Solution if finding the optimal solution for meeting integer requirement；If unmet integer requirement is most
Excellent solution, then in adding it to treat branch problem queue P.And the desired value of former relaxation problem is set under the minimum of former problem
Boundary.
WHILE(layer≤layerMax)DO
Step 3：Judgement treats whether branch queue P is empty.It is to jump out major cycle, from integer feasible solution, finds out former problem
Optimal solution；Otherwise perform step 4.
Step 4：Choose lax subproblem successively from branch's queue is treated and carry out branch's solution according to branch's principle, and
It is deleted from P, treats that a branch updates the minimum Lower and upper bounds of former problem after finishing, while obtaining the branch next time
Father's problem matrix P.
Step 5：According to branch principle is cut, father's problem matrix P is updated.
Step 6：Layer=layer+1.
