Transportation problem and sensitivity analysis

Najzanimljiviji linearni programi koji se pojavljuju u praksi uključuju velik broj varijabli i ograničenja, pa ih se mora rješavati upotrebom računala. Iz ovog razloga, cilj objašnjavanja simpleks metode nije samo zbog rješavanja problema na papiru, već razumijevanja računalnih programa s kojima se mogu susresti. Linearno programiranje optimizacijska je metoda kojom se određuje optimalna vrijednost linearne funkcije više varijabli (tzv. funkcije cilja) obzirom na neke zadane linearne uvjete koje varijable moraju zadovoljavati. Dakle, transportna ili prijevozna usluga je kretanje ljudi i dobara s jednog mjesta na drugo. Načini transporta jesu zračni, željeznički, cestovni, voda, kablovi, cjevovodi i prostor. Transportna polja mogu se podijeliti u tri grane: transportna infrastruktura, vozila i transportne operacije. Temeljni elementi razvoja transporta su sredstva za rad, predmet rada i radna snaga, odnosno sam rad.The most interesting linear programs that appear in practice include a large number of variables and constraints, so they have to be solved using computers. For this reason, the aim of explaining the simplex method is not just to solve paper problems, but to understand the computer programs that can be encountered. Linear programming is an optimization method that determines the optimal value of a linear function of multiple variables (so called goal functions) with respect to certain default linear conditions that variables must meet. Thus, a transport or transport service is the movement of people and goods from one place to another. The modes of transport are air, rail, road, water, cables, pipelines and space. Transport fields can be divided into three branches: transport infrastructure, vehicles and transport operations. Basic elements of transport development are the means of work, work and workforce, that is, the work itself
