Hi, for example you can find interesting applications of linear programming in the attached paper

3-D Bin packing - when packing groceries, your suitcase, build your bookshelf, or arrange your books in it, storing hobby things, or the left-overs in the basement. :-)

People who are on a diet can optimize it so that it matches the nutritional values and maximizes its tastefulness - or minimizes its cost. (The diet problem is a classic LP one.)

If you use public transport to get to and from work you might have several options on from where you board the transit system, where you get off, and what line you take, with a variety of uncertainties regarding the transit system's punctuality and the distance from your home or workplace to the nearest transit stop. There are plenty of optimization problems to think of in this situation - you may want to not walk very far to or from the transit stop, or you want to minimize the risk of missing a connection. And so on ...

I would add for example cutting stock problems - cutting pieces of solid materials into smaller elements in order to minimize the cost of purchasing the materials.

BTW, Michael Patriksson - what do you mean by "maximizing tastefulness"? Quantifying it by personal opinions of consumers in scale 0 to 10?

When talking about optimization regarding public transport, the fare optimization is also an important issue. Its necessity results from existence of complicated fare systems. It may include single tickets/passes with a period of validity, fares based on kilometric distances/zones, relation-based pricing (prices depending on start- and endpoints), multi-person discounts, discounts for specific groups of passengers (children, youth, students, seniors etc.), weekend/off-peak discounts, return discounts, advance purchase discounts including dynamic pricing...

All the best

Dear friend

We use operation research in ur daily life. Economic dispatch problem, iris data set, breast cancer are problems which I study in my research work. So u should follow my research paper. Where u understand about ur problem in better way

When you wait in line at ATM of a bank or at cashier's counter in a super market or to pump gas to your car, you apply Queueing Theory.

Dear colleague Kanticha Korsesthakarn, your question reminds me of ICIL 2006 in Kaunas. The moderator of one of the sessions insisted at the end of each talk if there were any intelligent questions. In one of the presentations the professor emeritus Ralph C. Huntsinger, without a doubt the most qualified person in the area that was in the room, intervened saying I do not have an intelligent question, I have a humble question.

I am very far from collecting the merits of Dr. Huntsinger, but like him, at that time, I confess that I have no brilliant ideas, but I would like to make my humble contribution.

For several years we have been concerned about the application of operations research (OR) to society as well as industry and we have completed some work, mainly in the area of risk, using different mathematical models, especially graph theory and multicriteria models.

In addition, we have used OR to establish tourist routes, as well as to solve logistical problems, especially focused on reverse logistics and with a focus on society, rather than on the company. Another use that we have made of multicriteria models is the location of vehicles to deal with emergencies and to prioritize projects in the social field.

We have also used OR models in the management of fantastic sports leagues. Also, more recently, we have used multicriteria models to see the influence of inadequate inventory regulations on society as a whole.

And less than a month ago we uploaded a couple of projects to Research Gate:

https://www.researchgate.net/project/Dissemination-of-knowledge-generated-by-the-interaction-of-fields-of-knowledge-Direct

https://www.researchgate.net/project/Dissemination-of-knowledge-generated-by-the-interaction-of-fields-of-knowledge-Indirect

With them the main objective is the Dissemination of knowledge generated by the interaction of fields of knowledge. One of these fields of knowledge is usually the OR. This project has allowed us to introduce the prime numbers in the kitchen.

I see very interesting the proposals of all the colleagues, who have intervened: Richard Epenoy, Michael Patriksson, Przemysław Kowalik, Rad Maythil, Sharandeep Singh, Jyotiranjan Nayak and P. S. Dharmapala, so I hope that our simple ideas will also be useful.

Greetings and good luck in your research.

You can utilize OR to discard/invite people from/to your team/life even you can find a partner to live with, place/city/house/country for living, company/job selection for maximizing your satisfaction and happiness etc...Good luck.

I consider Leonard Euler the father of operations research ! In 1744 he proclaimed his truely brilliant idea that "Nothing at all takes place in the universe in which some rule of maximum or minimum does not appear". Now take your pick ! (If you look at the2017Springer book Linear and Nonlinear Optimization by Cottle and Taha you will find this proclamation also in Latin. ) In engineering, almost any interesting situation will do.

The optimal way to produce a research paper, a kind of 'brilliant idea'.

In "maximizing tastefulness" I do refer to personal opinions, yes. :-)

Again, greetings to all the esteemed colleagues who are followers of this question. Last week I submit to the Research Gate platform, the Spanish version and the English version of the work: Multicriteria models to evaluate social development projects [New version], what we assume may be in the interest of all of you.

I apologize to those who receive this information multiple times, since I am sending it to several questions related to the subject.

Thank you for your attention and I hope you find the information useful.

Best regards,

José Hernández.

A useful application of OR can be reducing the waiting time of vehicles at Traffic light by optimizing the cycle time at each intersection .

Shyan, this is not an optimization, as you are at the red light; maybe you could count the optimization of the lane to pick, but you are not the main decision-maker - the algorithm in the red-light system is.

The same goes for Parakrama Sunil Dharmapala - you typically have no choice, as the ones ahead of you have a higher decision-making power.

Load cells can be deployed to estimate the vehicular density at any point of time and this real time data can be utilized by the system in selecting the signal duration to optimize the waiting time for the cycle.

Take the quickest route in the graph from the entrance through the shop to the exit, in which nodes are places where you want to pick up something to buy.

And keep a safe distance between you and others.

Check out the knapsack problem .. Daily and fun!

Kanticha Korsesthakarn - I think the COVID virus should be central to your idea. What do you think? What can you ask?

Dear Kanticha Korsesthakarn,

O.R. is a problem solving and decision taking technique. It is considered a kit of scientific and programmable rules which provides the management a “quantitative basis” for decisions concerning the operation under its control. Preparation of forecasts for the various inventory items and computation of economic order quantities and reorder levels. Scheduling and sequencing of production runs by proper allocation of machines. Transportation loading and unloading, Warehouse location decision.

OR for a planning

The navigation system takes up this problem and solves it – with the aid of Operations Research. Here, the route planner uses algorithms which are also deployed in OR and which function as follows: All calculations are based on a model. The navigation system is limited here to the aspects which are decisive for modeling, i.e. driving, the type of road, speed regulations, road closures or traffic jams. While working together on the development process, future users tend to bring the optimization problem to the surface – and bring the complexity along with it.

(i) Forecasting weathers

(ii) Transportation loading

(iii) Warehouse location decision

(iv) Road speeds

(v) Using of Laptop, mobile

(vi) Manufacturing activities at production terminals

(vii) Rapid Prototype

(viii) 3D-Bin packing

OR can be applied to 3D printing to fight against COVID 19 to manufacture mass production of ventilator, N95 mask and personal protective equipments using Assignment Problem, inventory control model and simulation OR approach.

Hope content is well and good.

While the above list is pretty good, I think newcomers shall be given web addresses to sites where more details are given.
