Table I below defines the precedence relationships and work element times for a new model toy. Table 1: Work Element Work Element Preceded by Time (Min) 1 0.5 2 1 0.3 3 1 0.8 4 2 0.2 5 2 0.1 6 3 0.6 7 4,5 0.4 8 3,5 0.5 9 7,8 0.3 10 6,9 0.6 (a) Construct the precedence diagram for the new model toy. (5 marks, C3) (b) If the ideal cycle time = 1.1 min, repositioning time = 0.1 min, and uptime proportion are assumed to be 1.0, find the theoretical minimum number of workstations required to minimize the balance delay under the assumption that there will be one worker per station? (5 marks, C3) (c) By using the Rank Positional Weighted Method line balancing algorithm, arrange the work elements to the station. (8 marks, C4) (d) Calculate the balance delay for solution in Question 3 (C). (2 marks, C4)
