Terzi – Room L01 ID Code Student (Surname – Name) Personal Code «T» «CognomeNome» «Codice_persona» Exercise 1 - 7 points- ONLY WHAT YOU WRITE IN THE DEDICATED SPACES WILL BE EVALUATED You are asked to design an automated transfer line that can perform the following processing cycle, using the “Ranked Positional Weighting” approach (also called Positional Weight Priority Index) following the Station Oriented Procedure and adopting MAXDUR as sub-criterion. Task Precedence Processing time (min) 1 - 0,31 2 - 0,5 3 1 0,3 4 1 0,24 5 1,2 0,12 6 3,4 0,33 7 5 0,29 8 6,7 0,38 9 7 0,25 10 8,9 0,45 Please, using a Theoretical Production Capacity (TPC) of 75 pieces/hours, compute the reference Cycle Time needed to balance the line. Then, draw the precedence diagram of the production tasks and calculate as well the minimum number of needed workstations. Please, state clearly your solution (allocating tasks in each single station according to the criteria specified above) following the schema proposed. At the end, calculate the line efficiency.
