IEOR 4000: Production Management Lecture 5 1 Professor Guillermo Gallego 9 October 2001 Aggregate Production Planning Aggregate production planning is concerned with the determination of production‚ inventory‚ and work force levels to meet fluctuating demand requirements over a planning horizon that ranges from six months to one year. Typically the planning horizon incorporate the next seasonal peak in demand. The planning horizon is often divided into periods. For example‚ a one

solution to linear programming problems can handle problems that involve any number of decision variables. 3- The value of an objective function decreases as its iso-objective line is moved away from the origin. 4- If a single optimal solution exists to a graphical LP problem‚ it will exist at a corner point. 5- Using the enumeration approach‚ optimality is obtained by evaluating every coordinate (or point) in the feasible solution space. 6- A non-unique solution to a linear program indicates

Q1.(a) What is linear programming problem? (b) A toy company manufactures two types of dolls‚ a basic version doll-A and a deluxe version doll-B. Each doll of type B takes twice as long to produce as one of type A‚ and the company would have time to make maximum of 1000 per day. The supply of plastic is sufficient to produce 1000 dolls per day (both A & B combined). The deluxe version requires a fancy dress for which there are only 500 per day available. If the company makes a profit of Rs 3.00

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
