In this paper, three assembly balancing methods were studied: largest Candidate Rule (LCR),. Kilbridge and Wester (KWC), and Ranked Positional Weight. KILBRIDGE & WESTER METHOD. Problem 2: The following list defines the precedence relationships & element times for a new model toy: Element. 1. 2. 3. 4 . 5. EXAMPLE 3: Kilbridge and Wester Method Apply the Kilbridge and Wester method to Example Problem 1. ‘ TABLE 4: Work Elements Assigned to Stations.

Repeat steps 2 and 3 for the other stations in the line until all the elements have been assigned. This is apparent when abd consider the following grouping:.

Learn how to solve the Rubik’s Cube with the easiest method. To assign elements to the first workstation, start at the top of the list and work down, selecting the first feasible element for placement at the station.

Assign the work elements in the work stations so that total station time is equal to or slightly less than the cycle time. This site uses cookies. You are commenting using your Facebook account.

Kilbridge and Wester Method Assignment Help

Westrn table also shows the T c value for each element and the sum of the T e values for each column. The manual methods to be presented are: This overcomes one weestern the difficulties kilbrjdge the largest candidate rule, with which elements at the end of the precedence diagram might be the first candidates to be considered, simply because their T, values are large.

Repeat step 4 for unassigned work elements: Continue till all work element are exhausted. However, our problem is elementary enough that many of the difficulties which the procedure is designed to solve are missing.


In general, the Kilbridge and Wester method will provide a superior line balancing solution when compared with the largest-candidate rule. One comment should be made which applies not only to the largest-candidate rule but to the other methods as well. Element 3 is not feasible because its immediate predecessor is element I, which has not yet been assigned, The first feasible element encountered is element 2.

Make a column I, in which include all work elements, which do not have a precedence kilbridte element.

Fill in your details below or click an icon to log in: It is a heuristic procedure which selects work elements for assignment to stations according to their position in the precedence diagram. Notify me of new posts via email. List all elements in descending order of T e value, largest T e methkd the top of the list. In the RPW line balance, the ahd of stations required is five, as before, but the maximum station process time is 0.

We begin the assignment process by considering elements at the top of the list and working downward. You have to memorize only 7 steps to fix a scrambled cube.


A ranked positional westetn value call it the RPW for short is computed for each element. The reader should follow through the solution in Table 6. Posted 10 days ago. The reader can see that the trend will be toward lower values of RPW as we get closer to the end of the precedence diagram.

However, the meghod realities of the line balancing problem may not permit the realization of this number. Discuss why corporate culture is such an important determinant of organisational success However, this is not always true, as demonstrated by our sample problem.


Make column II in which list all elements, which follow elements in column I. For element I, the elements that follow it in the arrow chain see Figure 6. Ranked positional weights method The ranked positional weights procedure was introduced by Helgeson and Birnie in [6].

T c in our sample problem is 1. You are commenting using your WordPress. Ranked positional weights method In Section 6. Posted 7 days ago. Station 1 illustrates this difference.


Kilbrdge quoting or paraphrasing from any material e. To select which elements from column II to assign, we must choose those which can still be entered without exceeding T c. The sum of the T e values for the columns is helpful because we can see how much of the cycle time is contained in each column. Have a Referral code? Number of stations would be:. Stay ahead in your courses Sign UP now. For convenience, include the T e value and immediate predecessors for each element.

Describe the marketing concept Outline and apply the elements of the marketing When added to the column I elements, T s would exceed 1.

More sophisticated techniques are required for more complex problems. Posted 11 days ago.
