Optimum Production Run Time Calculation

Given data:
- Annual production: 2400 items
- Setup cost: R 850
- Weekly production rate: 100 units
- Production cost per item: Rs. 5
- Annual storage and carrying: 10% of average inventory

Calculate the optimum production run time based on the given data.

Step 1: Determine the Economic Order Quantity (EOQ)
EOQ is the optimum order quantity that minimizes the total cost of ordering and holding inventory. It is calculated using the following formula:

EOQ = sqrt((2*D*S)/H)
Where,
D = Annual demand (2400 items)
S = Setup cost (R 850)
H = Holding cost per unit per year (10% of Rs. 5 = Rs. 0.50)

EOQ = sqrt((2*2400*850)/0.50) = 1225.19

Step 2: Calculate the number of production runs per year
The number of production runs per year can be calculated as follows:

Number of production runs = (Annual demand) / (EOQ)

Number of production runs = 2400 / 1225.19 = 1.96

Since we cannot have a fractional number of runs, we will round it up to 2.

Step 3: Calculate the production time per run
The production time per run can be calculated as follows:

Production time per run = (EOQ) / (Weekly production rate)

Production time per run = 1225.19 / 100 = 12.25 weeks

Step 4: Convert the production time to months
Since the question asks for the optimum production run time in months, we will convert the production time to months:

Production time per run in months = (Production time per run) / (Number of weeks in a month)

Production time per run in months = 12.25 / 4 = 3.06 months

Step 5: Calculate the optimum production run time
The optimum production run time is the time taken for one production run. It can be calculated as follows:

Optimum production run time = (Number of production runs per year) * (Production time per run in months)

Optimum production run time = 2 * 3.06 = 6.12 months

Therefore, the optimum production run time is 6 months (Option C).

Solution:

Given data:

Annual demand (D) = 2400 items
Set up cost (S) = R850
Weekly production rate (P) = 100 units
Production cost (C) = Rs. 5 per item
Carrying cost (H) = 10% of average inventory

Let us calculate the optimum production run time using the economic order quantity (EOQ) model.

1. Calculating the EOQ

EOQ formula is given by:
EOQ = √((2DS)/H)
where,
D = Annual demand
S = Set up cost
H = Carrying cost
EOQ = Economic order quantity

Substituting the given values, we get:
EOQ = √((2*2400*850)/0.1)
EOQ = 1960.6

Hence, the optimum production quantity is 1960 units.

2. Calculating the number of production runs

Number of production runs = Annual demand / EOQ
Number of production runs = 2400 / 1960.6
Number of production runs = 1.224

Therefore, we need to produce 1960 units 1.224 times in a year.

3. Calculating the optimum production run time

Optimum production run time = EOQ / P
Optimum production run time = 1960 / 100
Optimum production run time = 19.6 weeks

Since we need to produce 1960 units 1.224 times in a year, the total time required for production is:
Total production time = 19.6 * 1.224
Total production time = 23.96 weeks

Therefore, the optimum production run time is approximately 6 months (i.e., 23.96 weeks).

Hence, the answer is option C.
