Lineai' programming is a class of mathematical formulation models concerned with the
efficient allocation of limited resources to known activities with the objective of meeting a
desired goal. This study introduces the application of linear programming model on three
different industrial applications. The first application is concerned with the optimal production
rates of steel rods for factory 4 of libyan iron and steel complex in Musrata. The second
application of this paper is the optimal production cost in feed mix industry. This study has been
carried out for animal feed plant in Benghazi. The optimal transportation cost is the desired target
of the third application. This application has been done for soft drink factory at Bouatni. In this
aspect, the treated problem is of different varieties for the capacities of the available
transportation means . Different routes among source(s) and destination(s) and transshipment
process are the main configuration of this problem structure. Quantitative Systems for Business
(QSB"􀀀) software is used for solution procedure. The main recomendations and conclutions are
