Question 45616


Production Design And Process Planning

In this exercise, you will identify the appropriate anthropometric measurement to assess the design parameters of a student chair for a classroom of mixed students (50% males and 50%females). See Figure 1 below to check design parameters.

a) (9 points) Based on the anthropometric dimensions presented in the lecture slides, which anthropometric measurement is required for each design parameter mentioned in Figure 1(SD, SH, SW, BH, BW, and DH)? Explain your answers.

b) (12 points) For each anthropometric measurement identified in (a), which percentile(s) is(are) required for the adjustable seat design? Justify and explain in detail your answers.

c) (9 points) Examine in detail the pros and cons of designing products for a fixed percentage of a population. When is this approach likely to be problematic? Citeappropriate references.

Question 41022


Production Design And Process Planning

a) What is the purpose of Production Flow Analysis (PFA)? and what are the Pros and cons of using this approach?

b) Table Q5b shows the product family data and process routing information for products currently produced in a process (functional) layout. Your task is to use the Rank Order Clustering (ROC) technique to identify the relevant cells and their content. You need to include the sorted matrices in your answer and clearly state what m/cs and products you have allocated to each cell. Discuss any issues forthcoming from your cellular groupings.

Question 41021


Production Design And Process Planning

a) Manufacturing operations and their process types can be located along avolume/variety continuum. Provide a suitable 'process type' which would fitin the following positions and give an example where it might be used?

i)High volume low variety

ii)Low volume high variety

b) What are kanban systems? why are they used? and how are they controlled?

c) Calculate the capacity of the Kanbans and the inventory level given the following information:

Utilisation rate R =900/hr//////Delay time T= 40mins////Number of Kanbans = 4//////Operation Variation X = 10%

d) The following options have been proposed to reduce the inventory level for the situation outlined in (Q4b).

Option A: Capacity C is increased to 400 units3

Option B: X becomes 20% or

Option C: The delay time Tis halved orWhich option would you choose and why?
