Introduction

Production planning plays a critical role in ensuring that manufacturing operations align with demand forecasts while minimizing costs and optimizing resource utilization. For Mama’s Stuffin’, a seasonal food product with fluctuating demand, selecting the most suitable production strategy is essential for operational efficiency and profitability. This paper analyzes three potential production planning strategies: level production over 12 months, producing to meet demand monthly by adjusting the workforce, and maintaining a fixed workforce supplemented with overtime and subcontracting. Using the provided demand forecasts, cost parameters, capacity constraints, and workforce data, we evaluate each strategy to identify the most effective approach.

Demand Forecast and Cost Overview

The demand forecasts for Mama’s Stuffin’ over the 12 months range from a low of 1,000 pallets in spring and early summer to a peak of 9,000 pallets in November. Costs associated with production include regular production at $30 per pallet, overtime production at $40 per pallet, subcontracting at $50 per pallet, and holding costs of $2 per pallet per month. The initial workforce comprises 10 workers, each capable of producing 200 pallets per month, with hiring and firing costs of $5,000 and $8,000, respectively.

Analyzing the Production Strategies

1. Level Production Over 12 Months

Under the level production approach, the company would produce a fixed number of pallets each month, likely corresponding to the average demand, to stabilize workforce size and production schedules. Calculating the average demand: (2000 + 1000 + 1000 + 1000 + 1000 + 1500 + 2500 + 3000 + 9000 + 7000 + 4000 + 3000) / 12 ≈ 4,250 pallets per month. Producing at this level ensures steady workflow and minimizes hiring and firing costs but results in excess inventory during months of lower demand and stockouts during peak months such as November and December. The costs of holding excess inventory or incurring overtime/subcontracting during peak months must be factored into total costs. Nonetheless, this approach simplifies planning and provides workforce stability.

2. Produce to Meet Monthly Demand

This strategy involves adjusting workforce levels monthly to match demand precisely, minimizing inventory holding costs and avoiding excess stock. However, fluctuating workforce sizes require hiring and firing, which are costly, and may lead to operational instability. For example, during peak months like November and December, significant workforce expansion would be necessary, incurring high hiring costs, whereas during off-peak months, workforce reductions might be necessary. Smoothing production and workforce adjustments could be achieved by utilizing overtime and subcontracting, which, although more flexible, increase marginal costs and aggregate expenses.

3. Fixed Workforce with Overtime and Subcontracting

This approach maintains the initial workforce level of 10 workers, producing 2,000 pallets per month, and employs overtime and subcontracting to meet fluctuating demand. Overtime costs are $40 per pallet, while subcontracting costs are $50 per pallet. During months where demand exceeds regular production capacity, excess demand is met through these means, incurring additional costs. This strategy balances workforce stability and operational flexibility, reducing hiring and firing costs while accommodating demand variability. However, the total cost analysis must consider overtime and subcontracting expenses, especially during peak demand months.

Cost Analysis and Implementation

Applying this structured approach involves developing a linear programming model to optimize total costs across strategies. The model would minimize the sum of production, overtime, subcontracting, holding, and staffing costs, subject to capacity constraints, demand requirements, and workforce limitations. Excel Solver can be employed to solve this model, testing each strategy to identify the lowest total cost solution. For instance, in the fixed workforce strategy, the model may determine the optimal amounts of overtime and subcontracting needed per month. Conversely, the level production model could smooth production quantities and evaluate inventory storage costs, balancing it against reduced variable costs.

Conclusion

In conclusion, selecting between the three production strategies depends on cost considerations, operational stability, and demand variability. The fixed workforce strategy supplemented by overtime and subcontracting appears most adaptable to high demand months while maintaining workforce stability, potentially reducing overall costs associated with hiring and firing. The level production approach offers stability but may incur higher inventory costs during off-peak months. Producing precisely to demand minimizes inventory costs but increases flexibility costs. An integrated approach using linear programming and Excel Solver allows quantifying these trade-offs, ultimately guiding the selection of the most cost-effective and operationally feasible strategy for Mama’s Stuffin’.
