Linear Programming Model in Operation Research study is usually mathematical type of model which contains set of equations that represent objective function and constraints. The keywords in this article are Objective Function and Constraints‚ according to Heizer & Render (2008) Objective Function are mathematical expression expressed in linear programming designed to maximizes or minimizes some quantity‚ for example profit can maximized while the cost might be reduced. The objective function is also

Mycenaean artefacts Lions Head Rhyton The Lions Head Rhyton is a gold lion head made of hammered sheet metal in the shape of a lions head. Lions Head Rhyton was found in Grave IV‚ Grave Circle A Mycenae and dates to the 16th century BC. The lions head is beautifully crafted with ears‚ eyes down to the very last detail and is a very good replica of a lion’s head. It bears distinctive details such as the muzzle and mane. Historians believe that the lion represents an expression of natural strength

collection of these treasures can be seen at the National Archaeological Musuem in Athens. The Mycenaean were also literate and wrote in a script known as Linear B. This script is an early form of Greek which is unrelated from Linear A from the Minoan Civilisation of Crete. It has however been deciphered. Other examples of the script Linear B have also been found on Crete‚ which has led to the possibility that the island may have been invaded by the Mycenaean people at around 1500 BC. At around
