01. Line Balancing 1 P RIORITIZATION R ULES In the following exercise we will calculate the efficiency of each line, since the best solution should be the one with the highest efficiency - Balance the line with the different models ( MaxDur , M a xNFol , RPW ) In doing such a work, start always from scratch. You should apply TOP and SOP approach in the 3 models - Calculate the Balance Efficiency (Eb) of your designed solution (use formula below) ( ) = ∑ ( ) ( ) 1. MaxDur : The processing time of the i - th operation is considered as priority index. - Operations (those available) are ranked with descending order (thus setting as first the largest processing time ti). - Operations with larger processing time ti are thus assigned as soon as possible (when spare/idle time is more available …), thus having t he ones with smaller processing time available for filling - up. 2. MaxNFol : The largest number of operations immediately following the i - th operation is considered as priority index (NFollowing). - Operations with larger number of following operations are thus assigned as soon as possible, thus increasing the number of alternatives. - Subcriterion: MaxDur 3. Ranked Positional Weighting A task is prioritized by the cumulative assembly time associated with the task itself and its successors ( ) = + ∑ w in S(i) where: S(i) successor tasks to task i Different approaches (using the same rule) can be adopted: - “Task - oriented” - TOP , when the remaining idle time is not sufficient to assign the i - th operation, a new workstation is opened - “Station - oriented” - SOP , when the remaining idle time is not sufficient to assign the i - th operation, before opening a new station, other available operations are taken into consideration to fill - up Operation Work content…
