MET 421 Manufacturing Systems Exam 2026

About this paper

MET 421: A 2-page End of Course Examination for Manufacturing Systems (MET421) at the University of Buea College of Technology, Department of Mechanical Engineering, taught by Wilson/Ndongmo, dated 5th February 2026. Problem I is a case-study on cellular manufacturing at a fictional company, requiring students to discuss a manager's concern about the utility of cellular manufacturing in light of scientific management/Taylorism, explain at least three machine-cell designs, and apply the Rank Order Clustering algorithm to a 5x5 part-machine incidence matrix to find machine cells and part families. Problem III is a linear-programming product-mix problem (two TV models, shared picture-tube supply and labour-hour constraints) solved by corner-point evaluation. Problem IV asks for the graphical solution of a linear program with all-greater-than-or-equal constraints, whose feasible region is unbounded, leading to an unbounded maximum.
