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.

Make a column I, in which include all work elements, which do not have a precedence work element.
Stay ahead in your courses Sign UP now. This is illustrated in Figure 6. More sophisticated techniques are required for more complex problems. For large balancing problems, involving methdo several hundred work elements, these manual methods of solution become awkward.
The total time of the elements in column I is 0. Submit Your Questions Here! A feasible cycle time is selected.
Ranked positional weights method In Section 6. Largest-candidate rule This is the easiest method to understand. A ranked positional weight value call it the RPW for short is computed for each element.
Note that element 5 could be located in either column II or III without disrupting precedence constraints. The RPW takes account of both the T e value of the element and its position in the precedence diagram.
Starting with a given T c value, it is not usually clear how many stations will be required on the flow line. If an element can be located in more than one column, list all the columns by the element to show the transferability of the element.
To select which elements from column II to assign, we must choose those which can still be entered without exceeding T c. Seven column initial assignment Now, selecting cycle time is equal to 18 seconds we follow the steps: Email required Address never made public. Constraint the precedence diagram so that nodes representing work elements of identical precedence are arranged vertically in columns.
This overcomes one of the difficulties with 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. In the following section we survey some of these computerized approaches. Element 6 is the only one that can be entered. The total of their element times is 1.
One comment should be made which applies not only to the largest-candidate rule but to the other methods as well. Fill in your details below or click an icon to log in: In the RPW line balance, the number of stations required is five, as before, but the maximum station process time is 0. When added to the column I elements, T s would exceed 1. 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.
Leave a Reply Cancel reply Enter your comment here In general, the Kilbridge and Wester method will provide a superior line balancing solution when compared with the largest-candidate rule. Learn how to solve the Rubik’s Cube with the easiest method. The possible combinations of primes 17, 2 and 2 of work content time 68 min are as follows:.
6.5 METHODS OF LINE BALANCING
The corresponding balance delay is The RPW solution represents a more efficient assignment of work elements to stations than either of the two preceding solutions. Of course, the most desirable number of stations is that which satisfies Eq. The largest-candidate rule provides an approach that is appropriate for only simpler line balancing problems. Can you use the QA strategies and techniques described in this chapter to deal with other problems, Notify me of new posts via email.
Make column II in which list all elements, which follow elements in column I. Posted 8 days ago. The table also shows the T c value for each element and the sum of the T e values for each column.

Describe the marketing concept Outline and apply the elements of the marketing The work elements are selected for assignment to stations simply kilbrjdge the basis of lilbridge size of their T e values. Our tutors will make sure that you achieve the highest grades for your industrial management assignments.
To begin on the second station, element 3 from column II would be entered first. Assignment 1 – Hat World Overview For this individual assignment, you will use skills acquired You are commenting using your Facebook account.
Discuss why corporate culture is such an important determinant of organisational success Ahd in detail and Write a 10 or 8 different between cost indifference point and break even Posted 13 days ago. However, this is not always true, as demonstrated by our sample problem.
Transtutors is the best place to get answers to all your doubts regarding the Kilbridge Wester heuristic and steps in line balancing with examples.
Also listed are the immediate predecessors for each element. Continue the process of assigning work elements to the station as in step 2 until no further elements can be added without exceeding Metho 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.
