Most flange customers in Iran face challenges with delivery times from domestic manufacturers; often the delivery time for products is long, and employers lose time in the design and engineering stages due to urgent needs for items caused by problems that occur during projects. Now that the time for purchasing items has arrived, time is limited, and the flange manufacturer is also facing difficulties due to order volumes and issues with raw material supply as well as cash flow.

Often, manufacturers propose delivery times of 3 to 9 months even for very small requests. We decided to strengthen our product delivery times in the range of 30 to 90 days as our strength by designing parallel systems and complex production planning structures for the first time in the country's flange manufacturing industry.

Below, we will discuss some examples and the actions of Vandad Petro Sahel Company to shorten delivery times:

1- The role of planning in timely delivery of final products

In the manufacturing industry, production planning plays a critical role in ensuring smooth operation and efficient delivery of products. This includes coordinating different units such as sales and production, ensuring the availability of necessary materials, and issuing work orders. To carry out these tasks accurately and timely, a comprehensive system is required that relies on enterprise information. This comprehensive system was designed and implemented for the first time by Vandad Petro Sahel Company, a flange manufacturer in Iran.

3- The importance of production planning

Determining the production schedule and operation sequences is a key factor in the success of manufacturing companies. Production planning helps prevent capital accumulation, reduce waste, minimize machine downtime, respond quickly to customer orders, and ensure timely availability of raw materials and components. Scheduling issues in production are diverse, and production planning aims to optimize scheduling and prioritize tasks, thereby minimizing costs and increasing efficiency.

3- How production planning works at Vandad Petro Sahel Company:

Production planning can assist our organization in various aspects of production. Let's explain the methods we have implemented for you:

Optimizing production planning: Production planning assists production line managers in creating an efficient production schedule.

Reducing inventory: Effective production planning can reduce inventory levels and ensure that only necessary materials are stored, thus minimizing holding costs.

Increasing forecasting capability: Production planning enhances the organization's ability to forecast production status and aids in decision-making regarding order acceptance.

Minimizing outsourcing: By maximizing internal resources, production planning reduces reliance on outsourcing and optimizes the use of internal capabilities.

Optimal use of machinery and personnel: Production planning ensures the optimal use of machinery and personnel, maximizing productivity.

Effective management of products, parts, and waste: Production planning facilitates better management of products, parts, and waste.

Increasing profits and reducing costs: Optimized production planning results in increased profitability and cost reduction through efficient operations.

Improving customer satisfaction: Timely delivery of products due to efficient production planning leads to increased customer satisfaction.

Optimized machine production schedules: Production planning aids in determining the optimal production schedule for each machine.

Reducing machine downtime: Effective production planning minimizes machine downtime by eliminating waiting times for semi-finished parts.

Material Requirements Planning (MRP)

Material Requirements Planning (MRP) is a vital component of production planning. It ensures timely access to the required quantities of raw materials, semi-finished products, or intermediate products needed for the final product. MRP calculations are conducted within the production planning framework by determining production requirements based on the company's policies at each production unit.

Capacity Requirements Planning (CRP)

Capacity Requirements Planning (CRP) is essential for creating a production schedule. It allocates production resources based on factors such as operation start and end times, operation priorities, downtime, and machine usage to work centers. Then, these resource capacities are utilized in production planning calculations based on the capacity requirements.

A production order is an operational and execution plan prepared based on the production schedule for a shorter duration. It is produced based on the production plan to ensure that all necessary resources for each production stage are ready.

The importance of Lean principles and Six Sigma

Lean and Six Sigma are well-known methodologies used in production planning and operations management. Lean principles include Just-In-Time (JIT) production, Value Stream Mapping (VSM), and the 5S method. Its goal is to minimize waste and improve efficiency, and it has been widely implemented in various industries, including manufacturing and healthcare.

On the other hand, Six Sigma uses advanced statistical methods and tools to address variability in production processes. Its goal is to reduce defects and improve quality. Six Sigma projects are typically carried out by trained professionals, and many organizations have adopted this approach for continuous improvement.

While these principles have shown positive impacts on production planning and operations, it is important to note that they do not provide a comprehensive theoretical framework for production planning and management. They often overlook the realities of business operations and the natural behavior of production systems.

To better understand, let's compare the production management strategies of Henry Ford, the founder of Ford Motor Company, and Alfred P. Sloan, the former CEO of General Motors.

Henry Ford's production management strategy

Henry Ford revolutionized the automotive industry with his innovative production management strategy. He introduced the assembly line concept that enabled mass production of standardized products. Ford achieved significant gains in productivity and cost reduction by dividing the production process into specialized tasks performed by workers stationed along the assembly line. His goal was to minimize production time while maximizing output.

Alfred P. Sloan's production management strategy

Alfred P. Sloan, the visionary leader of General Motors, had a different approach to production management. He recognized the importance of product diversity and introduced the concept of product differentiation. Sloan implemented a decentralized organizational structure that allowed each division within General Motors to operate independently and serve different market segments. This strategy enabled General Motors to offer a wider range of products and effectively target the diverse needs of customers.

As a result, production planning plays a crucial role in ensuring the timely delivery of final products. It encompasses various aspects such as material requirements planning, capacity requirements planning, and production order management. Lean principles and Six Sigma provide valuable tools and techniques for optimizing production processes. However, it is important to consider the unique characteristics of each organization and industry when implementing these methods. By understanding the historical strategies of industry leaders like Henry Ford and Alfred P. Sloan, we can gain insights into different approaches to production management.
