Question 3 3. A South African company has employed you as industrial engineering trainee to assist with manufacturing process. One of your duties is to evaluate 2 proposals for assembling a product with an aim of selecting the best method of assembling the new product. Proposed methods are as follows: - Custom-built rotary types - Fully automated robotic type Data for each proposed type are as follows: Method 1: A custom-built rotary type workstation has two stations. The time allocation is as follows: Table 1: Time Allocation Station 1 2 Table 2: Equipment Cost Items Operating Time (min) 0.4 0.5 Transfer time = 0.1 minute Method 2: A robotic station is a single work piece-in-process type. A pallet with a base component is supplied on a conveyor (loading time = 0,1 min). The robot assembles a product in 1 min. Then a pallet with the complete product is removed (unloading time = 0,1 min). The bank lending rate is 22%. Initial cost Annual operating (R) Salvage value Service life The number of working days per year is 250 with an 8-hour shift. The equipment costs are provided below. Method 1 200 000 9 000 10 000 7 years [27] 100 000 6 000 5 000 5 years Method 2 F5 3.1 Determine the cycle time and production rate of each method. 3.2 Determine the unit cost of method 1. 3.3 Determine the number of units which can be produced annually by both methods. 3.4 What is the break-even quantity of units? 3.5 How would you provide an overview of the inspection test as well as coordination and control which one of the production operations? (4) Hint: provide the purpose and example of each of these phases (4) (4) [21] Question 3 3.
