Explanation:
The assignment model is used in operations research to solve problems related to assignment or allocation. This model involves assigning a set of tasks (or jobs) to a set of resources (or workers) in such a way that the total cost or time required is minimized. The assignment model can be represented mathematically using matrices.
Square Matrix:
A square matrix is a matrix in which the number of rows is equal to the number of columns. In other words, a square matrix has the same number of rows and columns. The assignment model is represented using a square matrix.
Rectangular Matrix:
A rectangular matrix is a matrix in which the number of rows is not equal to the number of columns. In other words, a rectangular matrix has a different number of rows and columns. The assignment model is not represented using a rectangular matrix.
Diagonal Matrix:
A diagonal matrix is a square matrix in which all the elements outside the main diagonal are zero. In other words, a diagonal matrix has non-zero elements only on the main diagonal. The assignment model is not represented using a diagonal matrix.
Unit Matrix:
A unit matrix is a diagonal matrix in which all the elements on the main diagonal are equal to 1. In other words, a unit matrix is a square matrix with 1's on the main diagonal and 0's elsewhere. The assignment model is not represented using a unit matrix.
Conclusion:
Hence, the correct answer is option 'A', which states that the matrix in the assignment model is a square matrix.
