To determine the frequency of production runs, we need to consider the demand for bearings from the customer, the production capacity of the manufacturer, and the cost factors involved.
Given data:
- Production capacity: 12,000 bearings per day
- Customer demand: 8,000 bearings per day
- Cost of holding a bearing in stock: Rs. 0.20 per month
- Setup cost per production run: Rs. 500
- Working days in a year: 300
Let's break down the solution into the following steps:
1. Determine the annual demand:
Annual demand = Customer demand per day * Working days in a year
Annual demand = 8,000 * 300 = 2,400,000 bearings
2. Calculate the number of production runs required:
Number of production runs = Annual demand / Production capacity
Number of production runs = 2,400,000 / 12,000 = 200 runs
3. Determine the cost of holding the bearings in stock:
Cost of holding bearings in stock = Cost per bearing * Number of bearings * Holding time
Holding time = 1 month = 1/12 year
Cost of holding bearings in stock = 0.20 * 12,000 * (1/12) = Rs. 240
4. Calculate the total setup cost:
Total setup cost = Setup cost per production run * Number of production runs
Total setup cost = Rs. 500 * 200 = Rs. 100,000
5. Determine the frequency of production runs:
Frequency of production runs = Total setup cost / Cost of holding bearings in stock
Frequency of production runs = Rs. 100,000 / Rs. 240 = 416.67
Since the frequency of production runs cannot be a fraction, we round it up to the nearest whole number.
Therefore, the frequency of production runs should be approximately 417 runs.
Converting this into days:
Frequency of production runs = 417 runs / 300 working days = 1.39 days
Rounding it up to the nearest whole number, the frequency of production runs should be approximately 2 days.
Therefore, the correct answer is option (c) 6.8 days.
