25W 135 G, W 0 and integers.
This mathematical program tries to maximize the profit as a function of the production quantities G and W , while ensuring that these quantities are such that the corresponding production is feasible with the resources available.
At the lowest level one might be able to use simple graphical techniques or even trial and error.
However, despite the fact that the development of spreadsheets has made this much easier to do, it is usually an infeasible approach for most nontrivial problems.
techniques are analytical in nature, and fall into one of four broad categories.Fassilia

Then the objective is to maximize total profits given by 10G 9W.
Then the objective is to maximize total profits given by 10G 9W.
There is a constraint corresponding to each of the three limited resources, which should ensure that the production of G gizmos and W widgets does not use up more of the corresponding resource than is available for use.
Thus for resource 1, this would be translated into the following mathematical statement 0.
0W 630 , where the left-hand-side of the inequality represents the resource usage and the right-hand-side the resource availability.
Additionally, we must also ensure that each G and W value considered is a nonnegative integer, since any other value is meaningless in terms of our definition of G and W.
The completely mathematical model is .Fassilia

In using a mathematical model the idea is to first capture all the crucial aspects of the system using the three elements just described, and to then optimize the objective function by choosing from among all values for the decision variables that do not violate any of the constraints specified the specific values that also yield the most desirable maximum or minimum value for the objective function.
This process is often called mathematical programming.
Although many mathematical models tend to follow this form, it is certainly not a requirement; for example, a model may be constructed to simply define relationships between several variables and the decision-maker may use these to study how one or more variables are affected by changes in the values of others.
Decision trees, Markov chains and many queuing models could fall into this category.
Before concluding this section on model formulation, we return to our hypothetical example and translate the statements made in the problem definition stage into a mathematical model by using the information collected in the data collection phase.
To do this we define two decision variables G and W to represent respectively the number of gizmos and widgets to be made and sold next month.Fassilia

, maximize profits and minimize changes in workforce levels, say .
In such cases there are two options.
First, one could focus on a single objective and relegate the others to a secondary status by moving them to the set of constraints and specifying some minimum or maximum desirable value for them.
This tends to be the simpler option and the one most commonly adopted.
The other option is to use a technique designed specifically for multiple objectives such as goal programming .Fassilia

, the specific decisions on the system or process that can be taken.
The third and final component of a mathematical model is the objective function.
This is a mathematical statement of some measure of performance such as cost, profit, time, revenue, utilization, etc.
and is expressed as a function of the decision variables for the model.
It is usually desired either to maximize or to minimize the value of the objective function, depending on what it represents.Fassilia
