Operational Research
INTRODUCTION:
Welcome to Operational Research app. This app is Solver or Calculator. It is useful to solve following problems:(1)Assignment Problem (2)Transportation Problem (3)Linear Programming (4)Sequencing Problem (5)Game Theory. This app will solve all variety of these problems as well as shows STEP BY STEP solution.
FEATURES:
-Simple and easy user interface.
-Beautiful design.
-Calculates multiple answers, minimization and maximization, balanced and unbalanced all.
-View all steps of solution along with marking and assigning steps in Assignment problem.
-View all steps of initial solution and optimization steps along with marking and looping in Transportation problem.
-Least cost, North-west corner, Vogel, Row-minima and Column minima method for Initial solution in Transportation problem.
-View all iterations in Linear programming Simplex Method.
-Solves infeasible, unbounded, minimization, maximization all in Linear programming.
-Shows all steps and time and idleness calculation in Sequencing problem.
-Solves problems arithmetically in Game Theory.
-Calculates all solutions in case of multiple solution.
-Saves history of solved problem. So, problem can be viewed any time.
-Matrix can have numbers of row and columns from 1 to 10.
What is Operational Research?
Operations research 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.
What is Assignment Problem?
-The assignment problem is one of the fundamental combinatorial optimization problems in the branch of optimization or operations research in mathematics. It consists of finding a maximum weight matching (or minimum weight perfect matching) in a weighted bipartite graph.
-The problem instance has a number of agents and a number of tasks. Any agent can be assigned to perform any task, incurring some cost that may vary depending on the agent-task assignment. It is required to perform all tasks by assigning exactly one agent to each task and exactly one task to each agent in such a way that the total cost of the assignment is minimized.
What is Transportation Problem?
The transportation problem is a special type of linear programming problem where the objective is to minimise the cost of distributing a product from a number of sources or origins to a number of destinations.
What is Linear Programming?
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.
What is Sequencing Problem?
Sequencing Problem is the selection of an appropriate order in which a number of jobs (Operations) can be assigned to to a finite number of service facilities (Machines or equipments) so as to optimize the outputs in terms of time, cost or profit.
What is Game Theory?
Game Theory is the branch of Operational Research concerned with the analysis of strategies for dealing with competitive situations where the outcome of a participant's choice of action depends critically on the actions of other participants. Game theory has been applied to contexts in war, business, and biology.

Hi. I am master of science in operations research; this app can use for many hard problems; this is excellent
Hello to my IE-4102 classmates. Download this! It is a very good app to solve operational research problem. Try it now!
I am really glad to know this app! It works well and gives a detailed solution.. it helped me a lot Thank you
Its a really good app for study .Thank yoy so much for this app but i request you to improve more new ways to solve question and analysing data.
Ohhh my god !! I really needed this app ! It's so simple and easy to understand. Thank you for this
Wonderful app...but plz add the graphical solution type also...rest all is very good👌
Excellent app.Very helpful and time saving.
Thank u so much for marking this app It's really helpful for me ❤❤ I hope u guys also make an app on financial management and direct tax Thank u so much 🥰🥰
Good but please improve some of the problems solving techniques
tickets not available there ad view option disabled please resolve as soon as possible
Excellent app for Operation research students
You have 10 "tickets" to see the solution. Need to watch ads to earn a ticket.
Very nice app but please add dynamic programming also ..
This app is very important in realisation problems operational recherch.. That is good.
It gives solution to each and every researcher requires
It's very useful app.we can easily learn problems from this app.
Really helpful this aap. Thank u so much making this aap because they app give tolal result.
Adds for tickets are not available many times
Great app i appreciate your work. THANKS FOR APP
Fortunately i found this app at task deadline..huff
This app is very use full for students
LPP problems are sloved using big M method only, other wise it is good if you want to match your answers to the questions...
plz clear all ads
Good app needs more functions
Love this app! So much helpful!
amazing app for students thanks to developers of this app
Perfect answer thanks for the wonderful app😇😇
Really great app👍 It helped me a lot thank you 😊
easily solved of problems
There are different methods of lpp, eg graphic, duality, two phase, but in this app the default setting is simplex method only. Extremely 😞 disappointed
