Read “Space Age Furniture Company” Respond to the following and include any Materials Requirement Planning (MRP) calculations: The Space Age Furniture Company manufactures tables and cabinets to hold microwave ovens and portable televisions. These products are made in various sizes and with various features, but all follow basically the same production and assembly operations. However, two of these products—the Saturn microwave stand and the Gemini TV stand—have a part (no. 3079) that requires machining on a special lathe used only for making that part. At present the machine is run by Ed Szewczak, a machinist who also operates other machines in Space Age's shop. Once set up and started, the lathe can run nearly unattended. However, the machinist must be present (even if not actually attending the machine) any time one of the machines, including the lathe, is in operation. At present, Ed works a regular 40-hour week. However, due to the workload for producing part 3079, it has been necessary to schedule frequent overtime for him in order to finish the necessary parts on time. Coral Snodgrass, operations manager for Space Age, has just heard from Ed's foremen that Ed is becoming unhappy about so much overtime. As Coral knows, Ed has been with the company a long time and is an excellent, reliable employee. Skilled machinists with Ed's experience and employment record are extremely difficult to find. Coral wonders what can be done to alleviate this problem. Recently, Space Age began using an MRP system that has helped reduce inventories greatly and improve on-time deliveries. In fact, Space Age carries no finished-goods inventory. Instead, everything in the master schedule is being produced for customer orders, so all products are shipped almost immediately. Previously Space Age had estimated that it cost $1.25 per week to store each Gemini and $1.50 per week to store each Saturn that wasn't shipped immediately. The master schedule for producing these two items for the next six weeks is shown below.

Paper For Above instruction

The Space Age Furniture Company faces complex challenges in optimizing its manufacturing processes, especially regarding materials requirement planning (MRP), inventory management, and workforce utilization. The need to balance production efficiency with employee satisfaction is critical, particularly when production involves specialized machinery and costly overtime. This paper develops an MRP system tailored to Space Age’s needs, examines the impact of lot sizes on demand and inventory costs, explores strategies for improvement, and analyzes the company's production mode. The overarching aim is to recommend practical solutions that enhance operational efficiency, reduce costs, and improve customer value.

Introduction

Manufacturing companies constantly strive to optimize production scheduling, inventory levels, and labor management to remain competitive and meet customer expectations. Space Age Furniture Company exemplifies these challenges, particularly with its reliance on specialized machinery—such as the lathe used exclusively for part 3079—and its current batch processing strategy. The company’s recent adoption of an MRP system has demonstrated potential benefits, including inventory reduction and improved delivery performance. However, issues persist in aligning production demands with capacity constraints, especially as the demand for sub-assemblies arrives in large, infrequent batches of 1,000 units. This situation creates lumpy demand that complicates production planning, increases inventory costs, and drives overtime, particularly for skilled operators like Ed Szewczak. This paper proposes ways to develop a refined MRP plan, address the limitations of large lot sizes, and suggest operational improvements to optimize manufacturing processes.

Development of an MRP System for Space Age Furniture

An effective MRP system begins with detailed demand forecasting derived from customer orders and the master schedule. For Space Age, the weekly schedule indicates precise quantities of the Saturn and Gemini products needed. The demand for part 3079, integral to both product lines, is driven by these orders. However, producing sub-assemblies in large lot sizes of 1,000 creates demand variability that causes inefficiencies. To develop an MRP, the first step involves generating gross requirements based on the master schedule. Subsequently, net requirements are calculated after accounting for current inventory and scheduled receipts. This process ensures that production planning aligns with actual demand, minimizing excess inventory and overtime.

Specifically, for part 3079, the company currently orders or produces in lots of 1,000 units. This creates a "lumpy" demand pattern that results in surplus inventory during low-demand weeks and shortages during peak periods. To address this, a just-in-time (JIT) approach or smaller lot sizes could be integrated into the MRP, aiming to smooth demand and reduce holding costs. Additionally, planning for frequent, smaller releases of sub-assemblies can align production more closely with weekly requirements, thus reducing the need for overtime.

Improvement Strategies over Lot Sizes of 1,000

One effective improvement involves reducing lot sizes of sub-assemblies from 1,000 to smaller quantities, such as 200 or 500 units. This change minimizes inventory buildup and increases flexibility in responding to demand fluctuations. Implementing kanban systems and continuous replenishment techniques further supports smaller batch sizes, leading to reduced lead times and lower inventory costs. These methods promote a pull-based production system where parts are produced only as needed, reducing waste and excess stock.

Another approach involves supplier-managed inventory (SMI), where suppliers produce and deliver components based on real-time consumption data. This method decreases the need for large batch orders and ensures part availability without large upfront investments. Moreover, adopting flexible manufacturing cells can enable quick changeovers, reducing setup times and allowing for more frequent batches that better match demand.

Trade-off Analysis: Overtime Costs vs. Inventory Costs

The trade-off between overtime costs and inventory costs is a central consideration in manufacturing operations. Overtime increases direct labor expenses and can lead to employee fatigue and dissatisfaction. Conversely, high inventory levels tie up capital, increase storage costs, and risk obsolescence. For Space Age, the current reliance on overtime to meet demand for part 3079 illustrates an imbalance. Reducing lot sizes can diminish overtime requirements by enabling production to be spread more evenly across scheduled hours, balancing capacity and demand.

A cost analysis reveals that overtime costs are generally higher on an hourly basis than inventory costs per unit. For instance, if overtime pay is 1.5 times the regular hourly wage, and inventory holding costs are $1.25 per week per unit, then frequent small batches can reduce total costs by lowering overtime expenses, despite potentially increasing ordering or setup costs slightly. A detailed cost model can quantify this relationship, guiding management in optimizing lot sizes to minimize total operational costs.

Calculating an Improved MRP and Addressing Demand "Lumpiness"

An improved MRP integrates smaller batch sizes, just-in-time components, and flexible scheduling to convert demand patterns from lumpy to steady. For part 3079, the weekly demand can be forecasted from the master schedule, and then planned in smaller quantities, such as 200 units, with safety stock buffers to cover variability. This approach reduces inventory holding costs and overtime-driven rush production.

Example calculation: If projected weekly requirement of part 3079 is 300 units, producing in batches of 200 units with a 20% safety margin results in 240 units per week. This smaller lot size aligns production closer to demand, minimizes inventory, and allows better capacity planning to avoid overtime. Also, lead times should be adjusted to reflect smaller batch sizes, ensuring availability without stockouts.

Comparison of Production Processing Types and Management Tracking

Space Age’s primary production mode appears to be batch processing, characterized by producing parts in largelots of 1,000 units, creating high inventories and irregular demand patterns. Unlike job shop or continuous production, batch processing balances flexibility and efficiency but may result in the "lumpy" demand issues observed. Job shop processing offers high customization but is less efficient for high-volume products. Continuous processing is ideal for high-volume, uniform products but does not suit the variability in furniture assembly.

To improve product tracking, management can implement real-time manufacturing execution systems (MES) that monitor each job's status, location, and progress. Barcoding and RFID technologies facilitate seamless tracking, providing visibility from start to finish. This transparency enables proactive scheduling, reduces delays, and improves overall responsiveness.

Recommendations for Enhancing Operations and Customer Value

Key recommendations include adopting smaller batch sizes, integrating lean manufacturing principles, and utilizing advanced MES for better job tracking. These strategies can lead to reduced inventory levels, lower overtime costs, and improved flexibility. Additionally, cross-training employees can address capacity constraints and reduce dependency on single skilled workers like Ed. Management should also explore flexible working arrangements, such as shift adjustments, to provide operational capacity without incurring excessive overtime costs.

Furthermore, embracing continuous improvement initiatives such as Kaizen can create a culture of efficiency, fostering ongoing evaluation and refinement of manufacturing processes. Investing in automation, where feasible, can further enhance productivity, especially in repetitive tasks. These steps not only improve internal efficiencies but also add value for customers through timely deliveries, customizable options, and better quality products.

Conclusion

Balancing operational efficiency with workforce satisfaction remains a critical challenge for Space Age Furniture Company. Developing an optimized, flexible MRP system that minimizes lot sizes and aligns production closely with demand can significantly reduce inventory costs and overtime dependency. Transitioning from batch to leaner, more responsive manufacturing processes, aided by modern tracking systems, enhances overall productivity and customer satisfaction. Strategic improvements in production planning, inventory management, and employee utilization are essential for sustaining competitive advantage in the furniture industry.
