Problem analysis:
Let x ij represent the decision variable X ij = 1 designate A i to do the work b jxij = 0 designate Ai not to do the work bj According to the requirements of the problem, everyone has to do a job, and each job needs one person to do it.
The detailed model will not be written.
Mathematical modeling is a mathematical structure obtained by simplifying assumptions and using appropriate mathematical tools according to its inherent laws and aiming at specific purposes.
Steps: Determine the purpose of the prototype, analyze the structure of the prototype, establish a professional model and solve the mathematical model.
