a) Explain the difference between concurrent engineering and sequential engineering. [4 marks] b) Describe three (3) major consequences of a poorly designed facility? [3 marks] c) List three (3) major factors that should be considered when deciding on the most suitable plant location. [3 marks] Three (3) Facilities location (A, B and C) are under consideration. The current values (V) of the facilities are $50,000, $38,000, $26,000 respectively. The three (3) alternatives outlined in table I have very different rankings on time required to fill customers order (T) and flexibility (F). The following weights have been assigned to the three factors (W, T and F): 0.4, 0.35, and 0.25. On a scale from 1 to 10, the following ratings have been assigned to the three alternatives for the three factors. A B C Present worth (W) 10 8 6 Full time (T) 7 10 8 Flexibility (F) 5 7 10 Table 1: Ratings for Alternative d) Using the weighted factor comparison method, which investment alternative would be recommended? [7 Marks] e) If another factor is introduced, safety (S), the weights assigned to the factors (W, T, F and S) are 0.3, 0.2, 0.15 and 0.35, and the rating for S are 10, 8, and 9 for A, B and C respectively, which investment alternative would be recommended?
