HRE2 PRODUCTION AND OPERATIONS MANAGEMENT MIDTERMS Facility Layout and Location Planning ▪ Types of facility layouts: product, process, cellular, and fixed-position ▪ Factors influencing facility location decisions ▪ Location analysis techniques: center of gravity, break-even analysis ▪ Practical examples of facility layout and location decisions FACILITY LAYOUT AND LOCATION PLANNING Facility location and layout are key components of production and operations management. Facility location involves selecting the optimal geographic site for operations to minimize costs and maximize efficiency. Facility layout refers to the arrangement of resources, machinery, and personnel within the facility to ensure smooth workflow, reduce waste, and improve productivity. Both decisions significantly impact operational success. TYPES OF FACILITY LAYOUTS Product Layout (Assembly Line Layout) ▪ In a product layout, equipment and tasks are arranged sequentially according to the steps involved in producing a specific product. Each workstation performs a fixed task as the product moves along the line. ▪ Best suited for: Mass production of a standardized product. ▪ Example: Automobile manufacturing. At a car assembly plant, each station handles a different part of the car's assembly (e.g., installing the engine, fitting the doors, adding electrical components). ▪ Advantages: High efficiency, low material handling costs, and reduced labor per unit produced. ▪ Disadvantages: Inflexibility, high setup cost, and susceptible to bottlenecks. Process Layout (Functional Layout) ▪ Equipment and similar tasks are grouped together based on function. This layout is common in job shops where a variety of products or customized items are produced. Products follow different paths depending on their needs. ▪ Best suited for: Low-volume, high- variety production. ▪ Example: A hospital, where departments are organized based on function, such as X-ray, surgery, and ICU, with patients moving to different departments based on their treatment needs. ▪ Advantages: Flexibility in handling a variety of products or services, and low equipment duplication. ▪ Disadvantages: Higher material handling costs and potential waiting times due to job movement between departments.  Cellular Layout ▪ Combines aspects of both product and process layouts by grouping different machines into cells that are used to produce a family of parts. This layout is designed to make the flow of work smoother by minimizing travel and handling times between stations. ▪ Best suited for: Medium-volume production with a variety of similar products. ▪ Example: In a manufacturing plant that produces different models of electronic components, each cell is responsible for a family of products that share similar manufacturing requirements. ▪ Advantages: Reduces setup times, improves flexibility, and reduces material movement. ▪ Disadvantages: Moderate capital investment required for reconfiguring existing layouts. Fixed-Position Layout ▪ The product remains stationary, and workers, materials, and equipment are brought to the site where the product is being assembled. This layout is common for large, heavy products or projects that cannot be moved easily. ▪ Best suited for: Large or immobile products, such as ships, airplanes, or construction projects. ▪ Example: Aircraft manufacturing at Boeing, where the plane remains in a fixed location, and workers and materials are brought to the assembly site to build the aircraft. ▪ Advantages: Allows production of large items that are difficult or impossible to move. ▪ Disadvantages: High labor costs and complex logistics to coordinate the movement of people and materials. FACTORS INFLUENCING FACILITY LOCATION DECISIONS 1. Proximity to Markets ▪ Companies want to minimize transportation costs and lead times by being close to their customers. Example: Amazon strategically places its fulfillment centers near major cities to ensure fast delivery. 2. Access to Labor and Skills ▪ Businesses seek locations where they can find workers with the required skills, and often at competitive wages. Example: Tech companies like Google and Apple set up facilities in Silicon Valley due to the availability of skilled software engineers. 3. Infrastructure Availability ▪ Adequate infrastructure (roads, power, water, and telecommunications) is critical for a facility's efficiency. Example: Toyota builds its manufacturing plants in areas with well-established infrastructure, such as Georgetown, Kentucky, to ensure uninterrupted production. 4. Government Regulations and Incentives ▪ Tax incentives, grants, and favorable labor laws can influence a company’s decision to locate in a particular area. Example: Tesla chose Nevada for its Gigafactory due to favorable tax incentives and energy policies. 5. Cost of Land and Utilities ▪ Land, utility costs, and local taxes significantly impact the total cost of setting up a facility.  Example: Factories are often located in rural areas or developing countries where land is cheaper. 6. Environmental and Community Considerations ▪ Companies are increasingly aware of the environmental impact of their operations and the importance of maintaining positive relations with the local community. Example: IKEA's Sustainable Practices and Community Engagement IKEA, the global furniture retailer, has a strong focus on environmental sustainability and community engagement in its facility location decisions. The company aims to use 100% renewable energy in its operations, with many of its stores and factories powered by solar panels and wind farms. Location: IKEA places some of its manufacturing facilities and stores in areas where it can minimize environmental impact, such as using sustainable materials and ensuring eco-friendly waste disposal systems. Community: IKEA is involved in community projects, such as supporting local jobs and sustainable development programs. In Sweden, the company works with the community to source sustainable wood, supporting responsible forestry. LOCATION ANALYSIS TECHNIQUES Center of Gravity Method ▪ A quantitative technique used to find the optimal location for a facility by minimizing the weighted distance between the facility and its customers or suppliers. The weights are usually determined by demand or shipment volumes. ▪ Example: A distribution company may use the center of gravity method to locate a warehouse that minimizes transportation costs to its retailers across different cities. Break-even Analysis ▪ A method that compares the total cost of different location options at various production levels. This analysis helps in determining the point at which each location becomes cost- effective. ▪ Example: A company deciding between building a factory in a high-cost urban area versus a low-cost rural area would use break-even analysis to understand how volume affects the profitability of each location option. Practical Examples of Facility Layout and Location Decisions ▪ Amazon Fulfillment Centers (Product Layout and Location Decision) Amazon uses a product layout in its fulfillment centers, where products move sequentially along conveyor belts for picking, packing, and shipping. The company's decision to locate fulfillment centers near large population centers helps minimize delivery times and costs. ▪ Ford Motor Company (Product Layout) Ford’s assembly plants follow a product layout, where each workstation on the assembly line has a specific task, leading to the mass production of cars. Ford’s choice of plant location often considers factors like proximity to suppliers, access to skilled labor, and local tax incentives. ▪ Starbucks (Location Decision)  Starbucks uses factors like proximity to foot traffic, demographics, and real estate costs when choosing store locations. For example, many of their stores are located in urban centers where the population density is high, ensuring maximum customer engagement. ▪ Boeing (Fixed-Position Layout) Boeing uses a fixed-position layout at its factories where airplanes are assembled. Workers and components move to the plane, which stays in a single position throughout the assembly process due to its size. PROBLEM ACTIVITY 1. A logistics company is planning to build a distribution center to serve three major retail stores in a city. The goal is to minimize transportation costs by selecting the optimal location for the center using the Center of Gravity method. The coordinates of the three retail stores and their respective weekly shipping volumes (in units) are as follows: ▪ Store A is located at coordinates (3, 5) and requires 100 units of products per week. ▪ Store B is located at coordinates (7, 8) and requires 80 units of products per week. ▪ Store C is located at coordinates (4, 2) and requires 120 units of products per week. Determine the best location for the distribution center using the center of gravity method. 2. A manufacturing company is deciding between two potential locations for a new factory. Location X has fixed costs of $200,000 per year and variable costs of $50 per unit produced. Location Y has fixed costs of $300,000 per year but lower variable costs of $30 per unit produced. The company expects to produce and sell its product for $100 per unit. Determine the break-even point in units for both locations and advise which location would be more cost- effective if the company plans to produce 5,000 units annually. CONCEPTS OF CAPACITY AND CAPACITY PLANNING Capacity refers to the maximum output that a system, organization, or facility can produce over a given period. It’s crucial in ensuring that businesses can meet customer demand without excessive delays or costs. Capacity is typically measured in units of production per time period (e.g., units per day). Capacity Planning is the process of determining the production capacity needed by an organization to meet changing demands for its products or services. Effective capacity planning ensures that resources like equipment, labor, and space are efficiently utilized, and that supply aligns with demand. Example: A bakery can bake 500 loaves of bread per day. If the bakery anticipates higher demand (e.g., during holidays), it needs to ensure it has the capacity— through extra shifts or additional ovens— to meet this increased demand. Short-Term vs. Long-Term Capacity Planning a. Short-Term Capacity Planning ▪ Short-term capacity planning focuses on managing capacity over a period ranging from a few days to several months. It deals with sudden fluctuations in demand and operational adjustments such as scheduling, overtime, hiring temporary staff, or leasing extra equipment. ▪ Goal: To respond to immediate changes in demand without committing to long-term investments. ▪ Example: A toy manufacturer may hire temporary workers or add shifts during the holiday season to meet the surge in toy demand. This avoids long-term investments in new equipment, which may not be needed after the holiday rush. b. Long-Term Capacity Planning ▪ Long-term capacity planning covers a longer horizon, usually several years, and involves strategic decisions such as investing in new facilities, acquiring additional machinery, or expanding operations. ▪ Goal: To ensure that the organization has enough capacity to meet future growth or sustained increases in demand. ▪ Example: A car manufacturer might build a new production plant if it anticipates a significant increase in demand for electric vehicles in the next five years. This involves substantial investment and long-term resource commitment. TECHNIQUES FOR CAPACITY PLANNING Demand Forecasting ▪ Demand forecasting involves predicting future customer demand using historical data, market trends, and statistical models. Accurate forecasting helps companies plan their capacity needs more effectively. ▪ Methods: Time series analysis, regression analysis, and qualitative forecasting (expert opinions, market research). ▪ Example: A clothing retailer uses historical sales data and upcoming fashion trends to predict future demand for specific garments. Based on these forecasts, they adjust their manufacturing and inventory to ensure they have enough capacity to meet expected sales. Capacity Requirements Planning (CRP) ▪ Capacity Requirements Planning is a method used to determine the amount of production capacity required to meet demand over a specific period. It calculates the resources needed (labor, machines, materials) based on the production schedule. ▪ Goal: To ensure that available capacity aligns with production plans and that there are no bottlenecks in the production process. ▪ Example: A furniture manufacturer uses CRP to calculate how many workers and how much machine time is needed to produce 10,000 chairs over the next quarter. The company adjusts its workforce and schedules machine maintenance based on this analysis. Case Studies on Capacity Management a.

It aims to optimize efficiency, reduce costs, and ensure timely delivery of products. SCM encompasses planning, sourcing, manufacturing, logistics, and customer service. Effective SCM enhances customer satisfaction and enables businesses to gain a competitive advantage. Example: In the automotive industry, SCM ensures that raw materials, components, and parts from various suppliers reach the manufacturer on time to produce cars, which are then distributed to dealerships and, ultimately, sold to customers. Key Components of a Supply Chain Suppliers ▪ Suppliers provide the raw materials or components required to produce goods. They are the starting point in the supply chain. ▪ Example: In a food supply chain, farmers are suppliers of raw materials like vegetables, fruits, and grains, which are then processed or packaged. Manufacturers Manufacturers convert raw materials or components into finished goods. They play a central role in determining product quality, lead time, and cost efficiency. Example: In electronics, companies like Apple manufacture devices like iPhones by assembling parts sourced from suppliers around the world. Distributors Description: Distributors act as intermediaries that transport goods from manufacturers to retailers or directly to consumers. They handle warehousing, packaging, and logistics. Example: In the pharmaceutical industry, distributors ensure that drugs manufactured by pharmaceutical companies are delivered to pharmacies, hospitals, and other healthcare providers. Retailers Description: Retailers are the final link in the supply chain, selling products directly to the end consumer. Retailers’ ability to manage inventory and offer products efficiently affects customer satisfaction. Example: Walmart, as a retailer, stocks products from various suppliers and manufacturers and sells them directly to customers through physical stores and online platforms. SUPPLY CHAIN COORDINATION AND INTEGRATION Supply Chain Coordination and Integration involves aligning processes, information flow, and activities across different stages of the supply chain to optimize performance. Effective coordination reduces delays, minimizes costs, and improves service levels by ensuring smooth communication and collaboration between all participants in the supply chain. ▪ Internal Integration o Streamlining processes within an organization (e.g., between procurement, production, and distribution departments).  ▪ External Integration Collaborating with external partners (e.g., suppliers, logistics providers, and customers) to improve efficiency. Example: Toyota uses a just-in-time (JIT) inventory system, closely coordinating with suppliers to ensure that parts arrive exactly when needed for production, reducing inventory holding costs and ensuring a smooth manufacturing process. Supply Chain Strategies: Lean, Agile, and Hybrid Lean Supply Chain A lean supply chain focuses on minimizing waste (time, inventory, and resources) and improving process efficiency. It emphasizes cost reduction and efficiency by streamlining operations and eliminating non-value-adding activities. Best Use Case: Stable, predictable demand with little fluctuation. Example: Toyota’s lean manufacturing system, which uses JIT principles, ensures that only the required parts are produced, avoiding overproduction and excess inventory. Agile Supply Chain An agile supply chain focuses on flexibility and responsiveness. It enables quick adaptation to changes in customer demand, market conditions, or unexpected disruptions. Agile strategies prioritize speed and customer service over cost efficiency. Best Use Case: Markets with volatile demand or rapid changes in customer preferences. Example: Zara, a fast fashion retailer, uses an agile supply chain to respond quickly to new fashion trends. It designs, produces, and delivers new clothing lines in just a few weeks, allowing it to stay ahead of customer demand. Hybrid Supply Chain ▪ A hybrid supply chain combines the lean and agile approaches. The front end of the supply chain (production) is managed using lean principles for efficiency, while the back end (distribution) is agile to respond quickly to changing customer needs. ▪ Best Use Case: Businesses facing stable demand for some products but unpredictable demand for others. o Example: Dell uses a hybrid approach, producing basic computer components using lean principles and customizing final products to customer specifications at the last stage of assembly, which requires agility to meet specific customer orders.
