How can linear programming be used




















For example, many large distribution companies will use linear programming in the analysis of their supply chain operations, similar to the toy example above. Additionally, linear programming can be used outside the warehouse in the optimization of delivery routes.

Companies like Amazon and FedEx use linear programming to find the shortest and most efficient delivery routes. Linear programming is also used in machine learning applications where a neural network is trained to fit model of a function in order to label input data and predict unknown future values.

It allows for matching the electric load in the shortest total distance between generation of the electricity and its demand over time. Linear programming can be used to optimize load-matching or to optimize cost, providing a valuable tool to the energy industry. She spent nine years working in laboratory and clinical research.

Yogurt products have a short shelf life; it must be produced on a timely basis to meet demand, rather than drawing upon a stockpile of inventory as can be done with a product that is not perishable.

Most ingredients in yogurt also have a short shelf life, so can not be ordered and stored for long periods of time before use; ingredients must be obtained in a timely manner to be available when needed but still be fresh. Linear programming can be used in both production planning and scheduling. To start the process, sales forecasts are developed to determine demand to know how much of each type of product to make.

There are often various manufacturing plants at which the products may be produced. The appropriate ingredients need to be at the production facility to produce the products assigned to that facility.

Transportation costs must be considered, both for obtaining and delivering ingredients to the correct facilities, and for transport of finished product to the sellers. The linear program that monitors production planning and scheduling must be updated frequently - daily or even twice each day - to take into account variations from a master plan.

Over cities worldwide have bikeshare programs. Although bikeshare programs have been around for a long time, they have proliferated in the past decade as technology has developed new methods for tracking the bicycles. Bikeshare programs vary in the details of how they work, but most typically people pay a fee to join and then can borrow a bicycle from a bike share station and return the bike to the same or a different bike share station.

Over time the bikes tend to migrate; there may be more people who want to pick up a bike at station A and return it at station B than there are people who want to do the opposite. Once other methods are used to predict the actual and desired distributions of bikes among the stations, bikes may need to be transported between stations to even out the distribution.

Bikeshare programs in large cities have used methods related to linear programming to help determine the best routes and methods for redistributing bicycles to the desired stations once the desire distributions have been determined. Learning Objectives In this section, you will learn about real world applications of linear programming and related methods.

Airline Scheduling Airlines use techniques that include and are related to linear programming to schedule their aircrafts to flights on various routes, and to schedule crews to the flights. Constraints involve considerations such as: Each aircraft needs to complete a daily or weekly tour to return back to its point of origin. Scheduling sufficient flights to meet demand on each route. Scheduling the right type and size of aircraft on each route to be appropriate for the route and for the demand for number of passengers.

Aircraft must be compatible with the airports it departs from and arrives at - not all airports can handle all types of planes. Additional constraints on flight crew assignments take into account factors such as: Pilot and co-pilot qualifications to fly the particular type of aircraft they are assigned to Flight crew have restrictions on the maximum amount of flying time per day and the length of mandatory rest periods between flights or per day that must meet certain minimum rest time regulations.

Numbers of crew members required for a particular type or size of aircraft. In this case the considerations to be managed involve: Getting aircrafts and crews back on schedule as quickly as possible Moving aircraft from storm areas to areas with calm weather to keep the aircraft safe from damage and ready to come back into service as quickly and conveniently as possible Ensuring crews are available to operate the aircraft and that crews continue to meet mandatory rest period requirements and regulations.

Kidney Donation Chain For patients who have kidney disease, a transplant of a healthy kidney from a living donor can often be a lifesaving procedure. For example a kidney donation chain with three donors might operate as follows: Donor A donates a kidney to Patient B.
