Students are getting burdened by the pressure of assignments and more. Especially students of management and specific other degrees have to spend a lot of time of these.
Are you facing the same problem?
If you are facing the same issues then you should know about operational research first. Only then you will be able to understand what is assignment problem in operational research?
Through this blog, you will be updated about operation research from the basic part. Then move on to further in this topic.
Most problems arise because people don’t understand the basics of a subject or topic. Without adequate basic knowledge, you will surely feel lost once you start going in-depth on this topic. Now take a look below for the utmost information on operation’s research!
What is operational research?
Operations or operational research refers to problem solving method as well as a decision making process which is analytical and is quite useful for an organization’s management team.
In this topic, you will learn about compartmentalizing of problems by the process of breaking it down and solve it step by step using mathematical analysis.
To understand what is assignment problem in operational research is you must know the analytical methods which consist of simulation, mathematical logic, queuing theory, game theory and network analysis.
Below are three steps which will help you understand the procedure without much hassle. The steps are:
- The first set or step might be enormous as an individual needs to develop solutions for an issue which has risen.
- All the alternatives that one derived before in the first step need analyzing. After such analyzing it, one should reduce the number of solutions and come up with ones which will most likely work.
- In this last step, all the solutions which would work are put into effect and if it is possible should be tested in situations which are applicable to the real world.
All of these techniques include mathematical models’ construction which attempts to explain the system. Due to statistical and computational nature of fields related in this, OR has robust ties to analytics and computer science.
If you become operational researcher then you will always face new troubles for which you must determine which technique is ideal for utilization to solve the issue due to the system’s nature, improvement goals, computing power as well as time constraints.
Now let’s have a look at what is assignment problem in operational research!
Assignment problem in operational research
Assignment problem is a combinatorial optimization issue in a branch of mathematics’ operations or optimization research.
In this, you have to find a match for maximum or minimum weight in bipartite weighted graph. According to the general form, the problems follow in the way below:
- The trouble instance comes with a definite number of individuals as well as tasks. If you are one of the individuals, then you might be assigned any task which needs to be completed. This will incur a charge; the exact amount will depend on the individual doing it as well as task itself. All the work should be performed by assigning a single individual for each job and it should be in a way through which total cost of assignment should be low or minimum to be exact.
If individual’s number, as well as work, is equal and also assignment’s total cost for every single task happens to be equal to each agent’s cost, then this issue is known as linear assignment problem.
Generally, if you are speaking about assignment issue without adding any qualification to it, then you are referring to a linear assignment problem. So, now you are aware of what is assignment problem in operational research.
Algorithms and more
There are numerous algorithms which are used for solving linear assignment problems that are bounded by a number of individuals’ polynomial expression.
One of the most common and popular is the Hungarian algorithm. A few other algorithms are an auction and simple algorithms’ adaptation.
Though you can opt for solving problems using a simplex algorithm, every specialization consists of a further efficient algorithm that is designed for taking benefit of its unique design.
Sub-disciplines in modern OR
In operational research, there are various sub-disciplines available. These include:
- Financial engineering
- Information and computing technologies
- Public sector and policy modeling work
- Management of supply chain, services science and manufacturing
- Revenue management
- Stochastic models
So, if you are opting for any of these sub-disciplines, you should have extensive knowledge about what is assignment problem in operational research along with operational research.
To have this, knowing about its historical origin is also essential. Have a look at it!
Historical origin of OR
In earlier times, Charles Babbage carried out operational research. His transportation cost research, as well as mail sorting, is what led to “Penny Post” in England in the year 1840. Also, it led to railway vehicles’ dynamical behaviour in GWR’s defence of broad gauge.
In 1920, Percy Bridgman conducted and brought OR in the world of physics. Moreover, later he attempted in extending it to social sciences as well.
You should know about these as it will make it crystal clear to you about how long operational research has existed in this world and from the earlier days how people utilized it in various ways to solve numerous problems.
Knowing about these will help you to understand what is assignment problem in operational research and more in detail.
We will come back to the history but before that get a glimpse of the origination of modern OR.
Modern OR’s origination
At UK’s Bawdsey Research Station modern OR originated in the year 1937. This was the outcome for the initiative which A.P. Rowe, station’s superintendent took. He gained this idea for analyzing as well as improving radar system of early warning in the UK.
He then analyzed radar equipment’s operational aspect as well as the communication network it had; expanding later the behaviour of operating personnel. This led to the revealing of CH network’s unappreciated limitations and also permitted to take remedial action.
With time, these kept evolving to a period which is what you will learn and understand when going through this topic at college.
Rise of modern OR during WWII
Want to know more about what is assignment problem in operational research? Keep reading!
This field got quite the recognition during Second World War.
During that era, OR was referred to as scientific approach for offering executive divisions with decisions depending on quantitative basis for operations under one’s control.
During World War II, a thousand men, as well as women, were engaged in OR in Britain.
Patrick Blackett is a person who worked in numerous organizations during this war. When he was associated with Royal Aircraft Establishment, his team ‘Circus’ that assisted in reducing a number of artillery round that needed to bring down aircrafts of the enemies.
Now that you are quite familiar with the operational research, it is time you get an insight into the problems addressed. Have a look below:
- Project planning or analysis for a critical path which is identifying specific procedures in various complex projects that will affect overall duration of projects undertaken.
- Floor planning refers to designing or structuring of equipment layout in factory or component which are there on computer chips for reducing manufacturing time which in turn reduces cost.
