Operational Research Handwritten Notes
Topics in our Operational Research Handwritten Notes PDF
In these “Operational Research Handwritten Notes PDF”, you will study the broad and in depth knowledge of a range of operation research models and techniques, which can be applied to a variety of industrial applications
The topics we will cover will be taken from the following list:
Introduction to Operations Research: Basics definition, scope, objectives, phases, models, and limitations of Operations Research. Linear Programming Problem – Formulation of LPP, Graphical solution of LPP. Simple Method, Artificial variables, big-M method, two-phase method, degeneracy, and unbound solutions.
Transportation Problem: Formulation, solution, unbalanced Transportation problem. Finding basic feasible solutions – Northwest corner rule, least cost method, and Vogel’s approximation method. Optimality test: the stepping stone method and MODI method.
Assignment model: Formulation. The Hungarian method for the optimal solution. Solving the unbalanced problem. Traveling salesman problem and assignment problem Sequencing models. Solution of Sequencing Problem – Processing n Jobs through 2 Machines – Processing n Jobs through 3 Machines – Processing 2 Jobs through m machines – Processing n Jobs through m Machines.
Dynamic programming: Characteristics of dynamic programming. Dynamic programming approach for Priority Management employment smoothening, capital budgeting, Stage Coach/Shortest Path, cargo loading and Reliability problems Games Theory. Competitive games, rectangular game, saddle point, min-max (max-min) method of optimal strategies, value of the game. Solution of games with saddle points, dominance principle. Rectangular games without saddle point – mixed strategy for 2 X 2 games.
Replacement Models: The Replacement of Items that Deteriorate whose maintenance costs increase with time without change in the money value. Replacement of items that fail suddenly: individual replacement policy, group replacement policy
Inventory models: Inventory costs. Models with deterministic demand – model (a) demand rate uniform and production rate infinite, model (b) demand rate non-uniform and production rate infinite, model (c) demand rate uniform and production rate finite.

Operational Research Notes FAQs
[sc_fs_multi_faq headline-0=”h2″ question-0=”What is Operational Research ?” answer-0=”Operations research (OR) is an analytical method of problem-solving and decision-making that is useful in the management of organizations. In operations research, problems are broken down into basic components and then solved in defined steps by mathematical analysis.” headline-1=”h2″ question-1=”What is Linear Programming ?” answer-1=”Linear programming is a powerful quantitative technique (or operational research technique) designs to solve allocation problem.” headline-2=”h2″ question-2=”What are Decision Variables ?” answer-2=”The decision variables refer to the economic or physical quantities, which are competing with one another for sharing the given limited resources.” headline-3=”h2″ question-3=”What is Objective function ?” answer-3=”The objective function of a linear programming problem is a linear function of the decision variable expressing the objective of the decision maker.” headline-4=”h2″ question-4=”What are Constraints ?” answer-4=”The constraints indicate limitations on the resources, which are to be allocated among various decision variables.” headline-5=”h2″ question-5=”What is non-negativity restriction ?” answer-5=”Non-negativity restriction indicates that all decision variables must take on values equal to or greater than zero” headline-6=”h2″ question-6=”What is Divisibility ?” answer-6=”Divisibility means that the numerical values of the decision variables are continuous and not limited to integers.” count=”1″ html=”true” css_class=””]
