Q.1. What is a linear programming problem ? Discuss the steps and role of linear programming is solving management problems. Discuss and describe the role of liner programming in managerial decision-making bringing out limitations, if any.
Ans : Linear Programming is a mathematical technique useful...
hierarchy (i.e., it paints a “big picture” of) the various types of mathematical optimization problems that can be solved with the MS techniques. Example problems and their mathematical formulations will be given in this initial stage, but the solution techniques will be discussed later. The idea is to...
representations or models to analyse problems. This distinct approach represents an adaptation of the scientific methodology used by the physical sciences.
OR methodology consists of five steps. They are defining the problem, constructing the model, solving the model, validating the model, and implementing...

Some firms use subjective methods, seat-of-the pants methods, intuition, and experience. There are also several quantitative techniques, moving averages, exponential smoothing, trend projections, and least squares regression analysis.
Eight steps to forecasting:
* Determine the use of the forecast—what...

Our framework starts with the identification and description of why banks pursue efficiency. In order to do so, we must first define bank production and show why and how production is optimized.
We introduce banks as rational economic agents. This concept merits some explanation. To start...

Q1. Explain how to transform an unbalanced transportation problem into a balanced transportation problem where the demand of warehouses is satisfied by the supply of factories.
If the total supply is more than the total demand, we introduce an additional column, which will indicate the surplus...
Linear Programming: As we have in the past, we will pose a problem and follow it through the steps of the model:
We have two types of boxed sets; the Aristorocks and the Millionaire sets. We have two people working in the boxing section and one person working in the shipping department. The Aristorocks...

Introduction
Linear programming (LP) models constitute one famous technique among optimization models that solve problems in which a measure of performance needs to be maximized or minimized under a set of constraints (or restrictions). LP's apply to a large variety of problems including resource allocation...

INTRODUCTION OF QUANTITATIVE TECHNIQUE
INTRODUCTION
People have been using mathematical tools to help solve problems for thousands of year; however, the formal study and application of quantitative techniques to practical decision making is largely a product of the 20th century. The technique we study...

for me, a substantial career shift from chemical engineering into OR (a shift made by many
at that time), but one which has been my life ever since. A useful source document available
to me at that time in NRIMS, was the set of notes prepared a few years years earlier...
