1. INTRODUCTION
Transportation model in Operation Research consists of two components which
are sources and destinations. Example for sources are factories, warehouses and example
for destinations are the places to deliver the products such as shops, warehouses and
stores. Each source is able to supply a fixed number of units of the product, and each
destination has a fixed demand for the product. Objectives of Transportation always to
minimize the cost.
Meanwhile, Linear Programming in Operation Research is a technique that helps
in resource allocation decisions. Linear Programming is a model consisting of linear
relationships representing a firm’s decisions given an objective and resource constraints.
Objectives of the business frequently to maximize profit or minimize cost. The four
components in Linear Programming model are decision variable, objective function,
constraints and parameters. Decision variables is a mathematical symbols representing
levels of activity of a firm. Objective function is a linear mathematical relationship
describing an objective of the firm, in terms of decision variables, that is maximized or
minimized. Constraints are restrictions placed on the firm by the operating environment
stated in linear relationships of the decision variables. Lastly, parameters are numerical
coefficients and constants used in the objective function and constraint equations.
