BASIC ASSUMPTIONS IN L.P.P ARE:
1.LINEARITY: Objective Function and Constraints must be expressed in linear inequalities
2.DETERMINISTIC:Coefficient of decision variable in objective function and constraints expression would be finite and known
3.Divisibility: Decision variable can be any non-negative value including fractions.

What is linear programming used for?
Linear Programming is used for determining a way to find the best solution or outcome for a given mathematical model represented as a linear relationship.
Characteristics of linear programming model?
Linear programming models involve optimizing an objective function subject to linear constraints. They assume additivity and proportionality in the relationships between decision variables and the objective function. Linear programming models also require non-negativity constraints on decision variables.
Explain what linear programming is and what the various models are?
the sequential flow of processes usually linear and its has two types which are: Waterfall and Prototyping Model
When formulating a linear programming model on a spreadsheet the measure of performance is located in the target cell?
true
What is meant by mathematical model in particular linear programming model?
A mathematical model is the representation of a relationship or state or phenomenon in a mathematical form using control variables.
Advantages and limitations of linear programming as a managerial decision making model?
It takes out the personal angle in decision making.
Do linear relationships show the same slope between any two points on a line?
Depends on your definition of "linear" For someone taking basic math - algebra, trigonometry, etc - yes. Linear means "on the same line." For a statistician/econometrician? No. "Linear" has nothing to do with lines. A "linear" model means that the terms of the model are additive. The "general linear model" has a probability density as a solution set, not a line...
Who are the author the visual basic?
Visual Basic (VB) is the third-generation event-driven programming language and integrated development environment (IDE) from Microsoft for its COM programming model. VB is also considered a relatively easy to learn and use programming language, because of its graphical development features and BASIC heritage.
Can a linear programming problem have multiple optimal solutions?
When solving linear prog. problems, we base our solutions on assumptions.one of these assumptions is that there is only one optimal solution to the problem.so in short NO. BY HADI It is possible to have more than one optimal solution point in a linear programming model. This may occur when the objective function has the same slope as one its binding constraints.
What are the essential characteristics of a linear programming model?
The LPP is a class of mathematical programming where the functions representing the objectives and the constraints are linear. Optimisation refers to the maximisation or minimisation of the objective functions. The following are the characteristics of this form. • All decision variables are non-negative. • All constraints are of = type. • The objective function is of the maximisation type.
What are the four basic elements of most communicating systems?
1- Sender (encodes a:) 2- Message (that is sent through a:) 3- Channel (to a:) 4- Receiver This is called a "linear model" of communication. It is the smallest and simplest system needed as if you take out one of its four components, there can be no communication.
What are the advantage of linear model?
advantages and disadvantages of linear model communication
