Aggregate Planning: Tips & Strategies

Introduction:

Strategic production planning is essential for businesses aiming to meet demand efficiently while maximising profits. Producing too few items results in lost revenue, while overproduction leads to increased storage and production costs. This is where aggregate planning comes into play. By balancing demand and capacity, aggregate planning ensures continuous and efficient production. In this article, we will explore the fundamentals of aggregate planning (AP), its objectives, methods, and best practices to help businesses streamline their operations and optimise resource utilisation.

Aggregate Planning

Analysing, establishing, and maintaining a manufacturing plan using aggregate planning emphasises uninterrupted, constant production. AP typically addresses 3-to-18-month sales predictions, inventory management, and production levels.

Production planning includes commodities and services. Aggregate planning determines the facilities, manpower, raw materials, and inventories needed to meet supply deadlines and reduce costs.

This applies to multiple production lines and products. It covers all facility or multiple facility occupations. This helps firms maximise their resources despite fluctuations in product demand, client orders, the supply chain, or other factors.

Creating an Aggregate Plan

The capacity and customer demand of units must be determined before creating an AP.

Here are some variables to consider when creating process consistency:

• Pricing: Lower prices to match capacity when demand is low. In reverse, raise prices when demand is high.
• Advertising/Promotion: Marketing and promotions affect product demand.
• Back Ordering: Delay delivery until demand meets capacity.
• Create a new demand to supplement an existing one.
• Workforce: You can hire or fire workers to meet demand or meet a shortage. Overtime, subcontracting, and temporary workers are options.

The Goal of Aggregate Planning

Aggregate planning determines the production, inventory, and manpower needed to meet medium-term demand fluctuations. With this knowledge, a business may predict demand spikes and guarantee it has enough merchandise. Manufacturers can also plan people, materials, output rates, timelines, and budgets with aggregate production planning.

The corporation avoids costly and risky production schedule changes by forecasting. Aggregate planning can predict medium-term demand and capacity accurately.

Manage Resources

You’re allocating short-term resources. This reduces overproduction, which wastes resources, lowers pricing, and oversaturates your goods. Labour and material costs are reduced by limiting output during low demand.

Cost-cutting

It helps companies meet financial goals and boost profits. It maximises output while fulfilling consumer demand, minimising wait time, and lowering inventory costs.

Data Must Be Good

However, AP forecasting is not foolproof. Forecasting is only as good as the data and people you use. Biases can cause economic indicator misreadings and forecast model errors. Material price increases, new policies, and interest rate changes are also unknowns. Changes in labour circumstances might trigger employee dissatisfaction.

Three Aggregate Planning Methods

Success requires an aggregate demand prediction for the planning term, capacity management evaluation (subcontractors, outsourcing, etc.), and workforce operating status. All of this improves accuracy and success.

This can be done with various aggregate planning methodologies. Three are the main ones organisations use:

1. Level approach: An aggregate planning approach maintains production and personnel levels. This requires good demand forecasting to determine if production levels should rise or decrease as client demands change. This aggregate production planning technique maintains manpower but increases inventory and backlog.
2. Pursuit Strategy: Chase market demand, as the term implies. Extra inventory isn’t kept because production matches demand. Waiting until an order is placed saves money in lean production. However, productivity and quality can decrease, lowering employee morale.
3. The Hybrid Strategy: A hybrid strategy is the third option. This balances production, manpower, and inventory while responding to demand. This option is flexible and can meet demand while lowering production costs.

Aggregate Planning Best Practices

AP requires some considerations regardless of strategy. First, calculate demand and capacity for each period. These two should match, however this may need overtime or subcontracting.

You should also identify union, departmental, and companywide policies that affect output. Cost is vital, therefore determine fixed, variable, and direct and indirect labour costs.

It’s good to have a backup plan. The same aggregate plan best practices should apply to these plans. If it fits your goals, it may cost less and be your principal aggregate production strategy.

Conclusion:

Effective AP is a cornerstone of efficient production management, enabling businesses to anticipate and respond to demand fluctuations. By utilising various AP strategies such as the level approach, chase strategy, and hybrid strategy, companies can optimise their production processes and resource allocation. Moreover, adhering to best practices in AP, such as accurate demand forecasting and cost management, ensures that businesses can meet their production goals while minimising waste and maximising profitability. With the right approach and tools, aggregate planning can significantly enhance a company’s ability to stay competitive and responsive in a dynamic market environment.
