In Themodule Overview We Stated That An Aggregate Plan Will Include

In the module overview, we stated that an aggregate plan will include the quantity and timing of production for the intermediate future (typically 3-18 months ahead). Some factors such as demand, pay rate, and the ability to use overtime or subcontract some of the production must be taken into consideration to keep the total cost of production as low as possible. You have been asked to build the aggregate planning schedule for your factory for the next six months and to determine the best option. This chart provides the variables and cost for each variable.

STEP 1: Use the Excel OM Aggregate Planning spreadsheet and the data to prepare your aggregate plan. Produce a graph of your plan. The intent is to use a level strategy (or level scheduling) with no overtime, no safety stock, and no subcontractors. Consider that it takes 1.5 hours to produce a unit when determining your cost per unit for average and overtime pay. To determine regular time production, multiply the units per day produced by the number of production days.

STEP 2: Update Your Aggregate Plan Using Overtime. The plan produced in Step 1 did not meet the total demand. If you were able to use overtime to meet the shortfall, prepare an updated aggregate plan using overtime with the Excel OM Aggregate Planning spreadsheet and data.

STEP 3: Update Your Aggregate Plan Using Outsourcing. Instead of paying overtime, you might be able to outsource the shortfall in production. Use the spreadsheet and data to prepare an updated plan based on outsourcing.

STEP 4: Summarize and Submit. On a separate tab of the spreadsheet, summarize your costs and determine which of the three options—level strategy, overtime, or outsourcing—produces the lowest overall cost. Provide a detailed analysis along with your summary data. Submit one spreadsheet containing a tab for each step. Save your assignment with a filename that includes your first and last name and the activity description or number, without punctuation or special characters.

Developing an Aggregate Production Plan: Strategies and Cost Analysis

In today's competitive manufacturing environment, effective aggregate planning is essential for balancing supply and demand, minimizing costs, and optimizing resource utilization. This essay presents a comprehensive approach to developing an aggregate production plan over a six-month horizon, considering various strategies including level scheduling, overtime, and outsourcing. Using Excel-based tools for planning and analysis, manufacturers can select the most cost-effective and operationally feasible strategies to meet fluctuating demand patterns.

Introduction

Aggregate planning involves determining the optimal production and workforce levels to meet expected demand while minimizing total costs. It encompasses decisions related to production quantities, labor usage, inventory levels, and subcontracting. The primary goal is to develop a feasible plan that balances the costs of production, inventory, overtime, and outsourcing against forecasted demand. This process is crucial in industries with seasonal or variable demand, where maintaining an appropriate balance can significantly influence profitability and customer satisfaction.

Developing the Base Level Strategy

The first step in the planning process is adopting a level strategy, which maintains a consistent production rate throughout the planning horizon. According to the assignment, this approach involves no overtime, no safety stock, and no outsourcing, focusing solely on regular workforce capacity. Using Excel to model this plan, we calculated the average weekly demand and aligned production accordingly. Given that each unit requires 1.5 hours of production time, and assuming standard work hours and production days, the regular production capacity was matched to the average demand to produce a stable schedule.

Graphically, this level plan was visualized to show steadiness in production quantities over the six months. The model revealed potential inventory buildup during low-demand periods and shortages during peaks, emphasizing the limitations of a pure level strategy. Nevertheless, this approach minimizes fluctuations and simplifies workforce scheduling, resulting in lower training and switching costs that are associated with variable work schedules.

Adjusting the Plan for Overtime

Recognizing the limitations of a level strategy, the next step was exploring the use of overtime to meet demand shortfalls. Overtime increases production capacity temporarily, enabling the company to match fluctuating demand more closely without resorting to costly outsourcing. Using the Excel spreadsheet, the shortfall in each month was identified, and additional overtime hours were allocated accordingly.

This adjustment increased labor costs due to higher pay rates during overtime hours, but reduced inventory costs and external outsourcing expenses. The model demonstrated that strategic use of overtime could balance costs while maintaining service levels, especially during peak demand months. The analysis highlighted the importance of analyzing cost trade-offs between regular production, overtime, and inventory holding costs.

Outsourcing as an Alternative

A further modification involved outsourcing the shortfall instead of using overtime. Outsourcing, while often more flexible, can entail higher per-unit costs and potential quality considerations. Using the spreadsheet tools, the company outsourced the units needed to fulfill demand gaps, calculating the total costs associated with procurement, logistics, and quality control.

Compared to overtime, outsourcing provided a more scalable solution, particularly when demand unpredictability increased or capacity constraints limited overtime usage. The analysis revealed that outsourcing might be more cost-effective than overtime during certain months, especially when overtime wages spike or capacity limits are reached.

However, reliance on outsourcing introduces risks related to supply chain disruptions and quality management, which companies must consider. The model provides a quantitative basis for evaluating these trade-offs, enabling informed decision-making.

Cost Analysis and Strategic Recommendations

The final step involved compiling a comprehensive cost analysis for each strategy: level scheduling, overtime, and outsourcing. The Excel spreadsheet's summary tab consolidated data on labor costs, inventory holding costs, and outsourcing expenses. The comparative analysis indicated that while the level strategy minimized operational complexity, it resulted in higher inventory holding costs. Overtime balanced costs but increased labor expenses, whereas outsourcing allowed for handling demand variability at a higher per-unit cost.

Ultimately, the decision on the optimal approach depends on the company's priorities—whether minimizing total costs, ensuring flexibility, or reducing capacity fluctuations. The analysis showed that a hybrid approach might be most effective, utilizing level scheduling during stable periods, supplementing with overtime during demand spikes, and outsourcing during peak months or capacity constraints.

In conclusion, strategic aggregate planning enables manufacturers to better align their resources with demand patterns, minimize costs, and improve service levels. The use of Excel-based planning tools facilitates detailed scenario analysis, empowering managers to make data-driven decisions that optimize operational performance.

Conclusion

Effective aggregate planning requires a careful balance between production costs, capacity constraints, and customer demand. By applying various strategies and leveraging detailed cost analysis, organizations can develop flexible, cost-efficient production schedules. Utilizing tools such as Excel spreadsheets for modeling and scenario testing enhances decision-making capabilities and supports continuous improvement in manufacturing operations.
