An electronics manufacturer in Singapore assembles Product X, which is commonly used in semiconductor manufacturing. A key component for Product X is Component A, and the manufacturer purchases this component from a vendor in Malaysia. Each unit of Product X requires two units of Component A. Currently, it takes 12 hours to assemble one unit of Product X. The manufacturer assembles 200 units of Product X per 8-hour shift and operates one shift per day. (a) Assume the manufacturer currently holds an average of 6,000 units of Component A in raw material inventory as a buffer. Investigate the current process performance by addressing the following questions: (i) Calculate the total number of units of Component A the manufacturer is currently holding on average. (5 marks) (ii) Compute the number of days of supply held in raw material inventory for Component A. (2 marks) (b) Performance data has been obtained from a machine used to assemble Product X and tabulated in Table 1. Discuss the performance of this machine by computing the following: (i) Availability rate of the machine. (3 marks) (ii) Performance rate of the machine. (3 marks) (iii) Quality rate of the machine. (3 marks) (iv) Overall Equipment Effectiveness (OEE) of the machine. (3 marks) Suggest any two (2) countermeasures that the manufacturer can implement to improve the OEE of the machine. (6 marks)
