deals with solving optimization problem, in which we want to maximize function (such as profit, expected return or efficiency) or minimize the function( such as cost. time or distance), Usually in a constrained environment. The recommended course of action is known as program : hence, the term MP is used to describe such problems. MP consist of 3 components (Elaborate 3 function) 1. Decision variable: - Which is controlled or determined by the decision maker 2. Objective Function:- Its to be

Lecture 1: Introduction 1 Optimization Problems We start with the utility maximization problem commonly seen in intermediate microeconomics. Example 1.1. Denote I a consumer’ monetary income, p1 and p2 the prices of two goods, s and x1 and x2 for their quantities. The budget set of the consumer is B = f(x1 ; x2 ) : p1 x1 + p2 x2 Ig: 1 where D X is the constraint set. The minimization problem can be de…ned similarly. f (x) have the same set of solutions, Theorem 1.1

performance of organisational units where the presence of multiple inputs and outputs makes comparisons difficult. This tutorial paper introduces the technique and uses an example to show how relative efficiencies can be determined and targets for inefficient units set. The paper also considers a number of practical issues of concern in applying the technique. Introduction There is an increasing concern with measuring and comparing the efficiency of organisational units such as local authority departments

Transportation Model 1 Transportation Problems • Transportation Problem – A distribution-type problem in which supplies of goods that are held at various locations are to be distributed to other receiving locations. – The solution of a transportation problem will indicate to a manager the quantities and costs of various routes and the resulting minimum cost. – Used to compare location alternatives in deciding where to locate factories and warehouses to achieve the minimum cost distribution configuration

Procedure of Creating Dimensionless Groups 1. List all Variables that are included in the problem 2. Express each variable in terms of basic dimension 3. Determine the required number of pi terms 4. Select a number of repeating variables 5. Form a pi term by multiplying one of the non repeating variable by the product of repeating variables each raised to an exponent that will make the combination dimensionless 6. Repeat step 5 7. Check all the resulting pi terms

Introduction to feedforward neural networks Introduction to feedforward neural networks 1. Problem statement and historical context A. Learning framework Figure 1 below illustrates the basic framework that we will see in artificial neural network learning. We assume that we want to learn a classification task G with n inputs and m outputs, where, y = G(x) , (1) x = x1 x2 … xn T and y = y 1 y 2 … y m T . (2) In order to do this modeling, let us assume a model Γ with trainable parameter vector
