In this paper the manufacture of pellets from extruded plastic strands is treated as a constrained nonlinear programming problem. Complete model development is given. The advantages and disadvantages of various optimization strategies and algorithms are discussed; a solution is also obtained by Johnson’s Method of Optimum Design (MOD). Substantial increases in production rates are indicated with attendant favorable changes in the energy consumed in the production of a unit mass of product.
