Your solar manufacturing facility is known for its solar panel production in Malaysia. However, over the past 60 months, the facility has faced maintenance challenges that impact its operational costs, as shown in Table 3. Table 3 / Jadual 3 Number of Breakdowns / Jumlah Kerosakan 0 1 2 3 4 5 Total / Jumlah Number of Months with Breakdown / Bilangan Bulan dengan Kerosakan 5 16 11 8 13 7 60 Each breakdown results in an average loss of RM5,000 due to downtime and maintenance expenses. The facility is considering entering into a preventive maintenance service contract, which would still lead to some breakdowns, averaging one per month, but would cost RM2,500 per month.
