Question: For the data given in previous Problem, solve the mixed model line balancing problem except use the ranked positional weights method to determine the order of entry of work elements.

Problem: Two models A and B are to be assembled on a mixed model line. Hourly production rates for the two models are: A, 25 units/hr and B,18 units/hr. The work elements, element times, and precedence requirements are given in the table below. Elements 6 and 8 are not required for model A, and elements 4 and 7 are not required for model B. Assume E = 1.0, E = 1.0, and Mt = 1.

(a) Construct the precedence diagram for each model and for both models combined into one diagram.

(b) Find the theoretical minimum number of workstations required to achieve the required production rate.

(d) Determine the balance efficiency for your solution in (c).
