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.

Email required Address methld made public. The manual methods to be presented are: Assign the work elements in the work stations so that total station time is equal to or slightly less than the cycle time. The possible combinations of primes 17, 2 and 2 of work content time 68 min are as follows:.

Kilbridge and Wester Method Assignment Help

However, this is not always true, as demonstrated by our sample problem. The interested reader is invited to consult the references, especially [2], 17], wdstern 11], which apply the Kilbridge and Wester procedure to several more realistic problems.

Discuss why corporate culture is such an important determinant of organisational success For large balancing problems, involving perhaps several hundred work elements, these manual methods of solution become awkward. 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.

Our tutors will make sure that you achieve the highest grades for your industrial management assignments. Top Kilbridge and Wester Method Experts.


A feasible element is one that satisfies the precedence requirements and does not cause the sum of the T e values at the station to exceed the cycle time T c. You can also interact directly with our industrial management tutors for a one to one session and get answers to all your problems in your school, college or university level industrial management. Posted 13 days ago. This is of eestern in determining feasibility of elements that are candidates for assignment to a given station.


Station 1 illustrates this difference. Continue the assignment procedure in order of column number until the cycle time is reached.

Starting with a given T c value, it is not usually clear how many stations will be required on the flow line. Assign elements to stations according to RPW, avoiding precedence constraint and time-cycle violations. When added to the column I elements, T s would exceed 1. For convenience, include the T e value and immediate predecessors for each element. Ranked positional weights method The ranked positional weights procedure was introduced by Helgeson and Birnie in [6].

The elements at the front of the diagram are selected first for entry into the solution. 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. This RPW value is 3.

Largest-candidate rule This is the easiest method to understand. Notify me of new comments via email. Seven column initial assignment Now, selecting cycle time is equal to 18 seconds we follow the steps: The total of their element times is westegn.

Describe the marketing concept Outline and apply the elements of the marketing List the elements in order of their columns, column I at the top of the list. Submit Your Questions Here!

In the RPW line balance, the number of stations required is five, as before, but the maximum station process time is 0. This site uses cookies. None of the methods guarantees an optimal solution, but they are likely to result in good solutions which approach the true optimum.



Now, looking at the previous table, little readjustment it work element is possible if the cycle time is extended to 18 min. Can you use the QA strategies and techniques described in this chapter to deal with jethod problems, We immediately see that the column II elements cannot all fit at station 1. We then start the search over again from the top of the list.

Number of stations would be: For element Xnd, the elements that follow it in the arrow chain see Figure 6. Continuing the procedure for the remaining stations results in the allocation shown in Table 6. You have to memorize only 7 steps to fix a scrambled cube. Steps 2 and 3 result in the assignment of elements 2, 5, 1, and 4 to station 1.

This overcomes one of the difficulties with the largest candidate rule, with which elements at the end of the precedence diagram kilbeidge be the first candidates to be considered, simply because their T, values are large. To begin on westrrn second station, element 3 from column II would be entered first. Fill in your details below or click an icon to log in: Constraint the precedence diagram so that nodes representing work elements of identical precedence are arranged vertically in columns.

Continue till all work element are exhausted.
