Solution of Linear Programming Problems Total views (274)  
Graphical method used to solve a Linear Programming Problem is limited to two decision variable problems. But most real life problems when formulated as LP model will have more than two decision variables. Thus, we need a more efficient method to suggest an optimal solution of such problems. A more general method known as "Simplex Method" is suitable for solving Linear Programming Problems with ......

Transportation Problem Total views (264)  
Some Linear Programming Problems involving several product sources and destinations may be solved by using a simplified version of LPP, such problems are usually referred as transportation problems. It is one of the sub classes of LPP in where, the objective is to transport various quantities of a single homogeneous commodity, that are initially stored at various origins to different destinations ......

Integer Programing Total views (260)  
In mathematical programming problems, some times the value of the results comes out to be negative and fraction. In such cases the solution is not optimal. In linear programming it is assumed that the decision variables can take continuous values that is, these could be fractions or integers. Integer programming deals with solutions where some or all the variables can assume integers non-nega ......

Queuing Theory Total views (265)  
A common situation occurring in everyday life is queuing or waiting in a line. Queues are usually seen at bus stops, ticket counters, clinics, bank counters, super markets, barber shops, traffic signals and similar places. Queues are also found in workshops where the machines or vehicles are to be repaired, at a tool crib where the machines wait to receive tools, trucks wait to be unloaded, a ......

Sequencing Total views (265)  
Sequencing problems are used to determine the order or sequence of jobs in which they should be processed. This helps in minimizing the total cost or time involved in the operation. Sequence is the order in which different activities are to be performed. Every organization wants to utilize its productive systems effectively and efficiently and maximize its profits by meeting the delivery deadline ......
