Let there be n jobs which are to be assigned to n operators so that one job is assigned to only one operator.
i = Index for job, i = 1, 2, … n
j = Index for operators, j = 1, 2, … n
Cij = Unit cost for assigning job 'i' to operator 'j'
1 if job i is assigned to operator j
Xij = 0 Otherwise
The objective is to minimize the total cost of assignment. If job I is assigned to operator 1, the cost is (C11X11). Similarly, for job 1, operator 2 the cost is (C12X12). The objective function is:
Minimize = ∑ni=1 ∑nj=1 Cij Xij …(1)
Since one job (i) can be assigned to any one of the operators, we have following constraint set:
∑ni=1 Xij = 1; for all j;j = 1, 2, ... n …(2)
Similarly for each operator, there may be only one assignment of job. For this, the constraint set is:
∑ni=1 Xij = 1; for all i;i = 1, 2, ... n …(3)
The non-negativity constraint is:
Xij > 0 …(4)
Minimize Z = ∑ni=1 ∑nj=1 Cij Xij
Subject to ∑ni=1 Xij = 1; for all j;j = 1, 2, ... n
∑nj=1 Xij = 1; for all i;i = 1, 2, ... n
Xij > for all i and all j.

we need the best nitril rubber formulation
I'm not sure what you mean, but the c assignment operator is the equal sign, =
Assignment is usually indicated using Pascal assignment notation (:=). E.g., x := x + 1. This avoids any confusion with the equality operator (=).
In Problem formulation method ,goal is a parameter to provide which (goal) is formulated in goal formulation method.that's why problem formulation must follow goal formulation. suacsecu
Yes, as no singularity can be observed, mathematical formulation is the only way to model it.
In goal formulation, we decide which aspects of the world we are interested in, and which can be ignored or abstracted away. Then in problem formulation we decide how to manipulate the important aspects (and ignore the others). If we did problem formulation first we would not know what to include and what to leave out. That said, it can happen that there is a cycle of iterations between goal formulation, problem formulation, and problem solving until one arrives at a sufficiently useful and efficient solution. @ oneous.com

The assignment problem algorithm is a method used to efficiently assign tasks to resources in a way that minimizes costs or maximizes efficiency. It works by finding the best possible assignment of tasks to resources based on certain criteria, such as minimizing the total cost or maximizing the overall productivity. This optimization process is achieved through mathematical calculations and algorithms that analyze various combinations of task-resource assignments to determine the most optimal solution.
An assignment may give you problems if you do not understand what the assignment asks you to do. An assignment without full instructions will put you at a disadvantage to complete.
Total supply must equal to total demand in the transportation problem,but each supply and demand value is 1 in the assignment problem.
The answer depends on what the problem is!
I think mathematical skill includes problem solving skill, skill to model and analyzea problem mathematically,
It means to work out the answer of a given mathematical problem.
