Level production planning is a strategy that maintains a constant output rate, production rate, or workforce level over the planning horizon. It is suitable for products with stable demand or seasonal demand that can be smoothed by using inventory or backorders. Level production planning can help reduce labor costs, hiring and firing costs, and overtime costs. However, it may also result in high inventory costs or customer dissatisfaction due to long lead times or stockouts. To overcome these drawbacks, the company can investigate subcontracting to meet the extra demand during the peak season. Subcontracting is the process of outsourcing some or all of the production to another firm. It can help the company increase its capacity, flexibility, and responsiveness without investing in additional facilities or equipment. Subcontracting can also reduce the risk of obsolescence or spoilage of seasonal products.

Option B is not appropriate, because chase production planning is a strategy that adjusts the production rate to match the demand rate over the planning horizon. It is suitable for products with highly variable or uncertain demand that cannot be smoothed by using inventory or backorders. Chase production planning can help minimize inventory costs and avoid overproduction or underproduction. However, it may also result in high labor costs, hiring and firing costs, and overtime costs. Moreover, it may limit the company’s ability to capture the market share and satisfy the customer demand during the high demand season.

Option C is not appropriate, because hybrid production planning is a strategy that combines the features of level production planning and chase production planning. It is suitable for products with moderate variability or uncertainty in demand that can be partially smoothed by using inventory or backorders. Hybrid production planning can help balance the trade-offs between inventory costs and labor costs. However, it may also increase the complexity and difficulty of coordinating the production and demand plans. Moreover, it may not address the company’s financial constraints or capacity limitations.

Option D is not appropriate, because reducing the size of the customer base during the high demand season is a risky and counterproductive move. It may result in losing loyal customers, damaging the company’s reputation, and forfeiting potential profits. It may also create an opportunity for competitors to gain market share and customer loyalty.
