The purpose of this paper is to survey and express the advantages and disadvantages of the existing approaches for solving grey linear programming in decision-making problems. After presenting the concepts of grey systems and grey numbers, this paper surveys existing approaches for solving grey linear programming problems and applications. Also, methods and approaches for solving grey linear programming are classified, and its advantages and disadvantages are expressed. The progress of grey programming has been expressed from past to present. The main methods for solving the grey linear programming problem can be categorized as Best-Worst model, Confidence degree, Whitening parameters, Prediction model, Positioned solution, Genetic algorithm, Covered solution, Multi-objective, Simplex and dual theory methods.
In business and in day-to-day living we know that we cannot simply choose to do something because it would make sense that it would unreasonably accomplish our goal. Instead, our hope is to maximize or minimize some quantity, given a set of constraints. Your hope is to get there in as little time as possible, hence aiming to minimize travel time. While we have only mentioned a few, these are all constraints —things that limit you in your goal to get to your destination in as little time as possible. A linear programming problem involves constraints that contain inequalities. An airline offers coach and first-class tickets. For the airline to be profitable, it must sell a minimum of 25 first-class tickets and a minimum of 40 coach tickets.

OR-Notes are a series of introductory notes on topics that fall under the broad heading of the field of operations research OR. They are now available for use by any students and teachers interested in OR subject to the following conditions. A full list of the topics available in OR-Notes can be found here. A company makes two products X and Y using two machines A and B. Each unit of X that is produced requires 50 minutes processing time on machine A and 30 minutes processing time on machine B. Each unit of Y that is produced requires 24 minutes processing time on machine A and 33 minutes processing time on machine B. At the start of the current week there are 30 units of X and 90 units of Y in stock.
To address this issue, businesses have incorporated better strategies that will help identify transportation issues and develop the appropriate solutions. Based on Transportation Problems and Assignment Problems. There are many issues surrounding the low initial-cost provision of gravel roads. Unfortunately, although transportation planners recognize their potential benefits, they often treat them as last resort measures, to be used to address specific congestion and air pollution problems where conventional solutions prove to be ineffective. Solutions for First Order Equations Consider first the problem of finding the general solution for the equation tu x,t V x u x,t 0 for all x,t.
Linear programming LP , also called linear optimization is a method to achieve the best outcome such as maximum profit or lowest cost in a mathematical model whose requirements are represented by linear relationships. Linear programming is a special case of mathematical programming also known as mathematical optimization. More formally, linear programming is a technique for the optimization of a linear objective function , subject to linear equality and linear inequality constraints. Its feasible region is a convex polytope , which is a set defined as the intersection of finitely many half spaces , each of which is defined by a linear inequality. Its objective function is a real -valued affine linear function defined on this polyhedron. A linear programming algorithm finds a point in the polytope where this function has the smallest or largest value if such a point exists. Linear programs are problems that can be expressed in canonical form as.

A mixed integer programming problem is a mathematical programming problem in which at least one, but not all, of the components of x 2 S are required to be integers. In linear programming problems of maximum profit solution or minimum cots solution always occurs at a corner point of the set of the feasible solution. Strictly speaking, this isn't necessary, but I think it makes the solution cleaner and easier to generalize. It will enormously ease you to see guide.

Several word problems and applications related to linear programming are presented along with their solutions and detailed explanations. Methods of solving inequalities with two variables , system of linear inequalities with two variables along with linear programming and optimization are used to solve word and application problems where functions such as return, profit, costs, etc. Example 1. A store sells two types of toys, A and B. How many units of each type of toys should be stocked in order to maximize his monthly total profit profit? Hence the store owner has to have toys of type A and toys of type B in order to maximize his profit. Example 2.
