Operations Management: Modern Tools for Optimization

Understand how operations manage the systems that produce products and services, from inventory to waiting lines, and guide how we get things done in work and daily life.

Learn how value, the ratio of what customers get to what it costs, and productivity, output over input, guide better products, service, and cost decisions to satisfy customers and investors.

Learn how operations manage business processes and systems to deliver high-quality products and services efficiently, using fewer resources. Apply this across electronics, retail, dining, and digital products.

Explore how demand, purchase quantities, storage, and costs drive key inventory decisions from home to business, balancing bulk discounts with risk of waste and obsolescence.

Analyze how buy, order, and hold inventory costs, plus stockouts, shape total cost decisions and optimize when to replenish and store goods.

Apply the economic order quantity to minimize total inventory costs. Use the formula sqrt(2 D S / H) and see how D, S, and H shape the optimal order size.

Learn how data analytics and both quantitative and qualitative forecasting guide inventory decisions by predicting demand, holding and ordering costs, material costs, and production pace.

Explore make to stock, make to order, and assemble to order production strategies, with restaurant examples showing how market demand, inventory, and flexibility shape operations decisions.

Explore how line flow and flexible flow facility layouts affect production speed, quality, and worker and customer experience, and learn how hybrid layouts balance efficiency and customization.

Identify the bottleneck as the system's weakest link and align planning to maximize the bottleneck's output, ensuring work in process inventory supports continuous flow.

Balance a production line with cycle time set by demand. Hit 20 units per hour, reduce bottlenecks, and protect workers from stress injuries.

Apply lean manufacturing to minimize waste, reveal problems by reducing inventory, and develop a focused factory with specialized staff delivering high quality, cost-effective services.

View the retail layout as a manufacturing line where the store guides shoppers along profitable paths, placing high-margin items on the perimeter to maximize experience and profits.

Explore how waiting lines reflect a civilized society by balancing customer time and company costs, while aligning customers, employees, and managers to deliver fast, fair service.

Explore how waiting lines affect fairness, stress, and productivity by comparing single-line versus multi-line systems, and by optimizing the workspace, customer perception, and take-a-number processes.

Explore waiting line dynamics by comparing arrival rate and service rate, show how adding workers lowers wait times, and guide managers in balancing demand, costs, and customer experience.

Explore waiting line systems by modeling a simple first-come, first-served queue with a single server, using arrival and service rates to estimate average customers in line and wait times.

Quality is subjective, tied to personal values rather than a universal formula; listen to your target market, understand their needs, and align marketing, sales, retail, and operations to deliver value.

Explore the dimensions of quality for products and services, including service response, tangible goods versus experiences, and how doctors, cars, and electronics illustrate quality in operations.

Benchmarking compares your processes against leaders to identify gaps and spur improvement. Gather data, analyze differences, and act by adapting best practices—creatively and sometimes across industries.

Explore how reliability multiplies across a product's parts, illustrated by a lamp with a weak bulb that limits overall performance, and recognize that simpler designs with fewer parts boost reliability.

Quality certifications signal commitment to quality through documented processes and audits, as ISO 9000 demonstrates, improving internal processes and boosting supplier credibility in global supply chains.

Explore the dmaic framework to define, measure, analyze, improve, and control processes toward 3.4 defects per million opportunities, and compare lean six sigma certification paths.

Categorize quality costs into four categories: internal failure, external failure, appraisal, and prevention, and invest to reduce internal failures, lower external costs, and build prevention to improve overall quality.
