Cycle time and Assign work elements and Delete the assigned elements
A task having 12 work elements and their logical relationship and time ( in Seconds ) taken is given in the table below.
Cycle Time: Select a feasible cycle time (CT). By a feasible time mean one for which TMax > CT > ∑Ti.Work Assignment: Assign work elements to the station , such that the sum of elemental times at a station does not exceed the cycle time C T. This assignment proceeds from column I to II and so on braking intra column ties using the criterion of minimum number of predecessors.Deletion: Delete the assigned elements from the total number of work element and repeat the above step until all the element are assigned.Assignment to next station: If the station time exceeds the cycle time due to the inclusion of a certain work element this work element should be assigned to the next station.
Repeat all above steps except first until all elements are assigned to work stations.
