Agenda Intro to Operations Analysis What is Analysis, Modeling, and Simulation (AM&S)? Case Studies Summary Questions & Discussion
3
Operations Analysis Operations Analysis is the analytical arm of the Systems Engineering discipline. It is the discipline of applying advanced analytical techniques and processes to provide information for better decision making.
4
Who Does Operations Analysis? Operations Analysts come from a variety of disciplines Aeronautical Engineering Mechanical Engineering Electrical Engineering Computer Science and Engineering Mathematics, Physics Operations Research Key Traits are Analytical Skills, Problem-Solving Capability, and Communication Skills Degree Masters 53% BS/BA 42% PhD 5% Approximately 600 Operations Analysts in Boeing IDS
5
What Do Operations Analysts Do? The Realm of Designers – Measures of Performance Range Speed Payload The Realm of Ops Analysts – Measures of Effectiveness Survivability Number of Targets Detected Lethality – Number of Targets Destroyed Number of Information Packets Sent/Received and Cost/Affordability Ops Analysts Work with the Design Team to Ensure the System Can Do Its Intended Job An Aircraft Example:
6
Tools and Methods Commonly Used Techniques Modeling and Simulation Linear and nonlinear programming Queuing and other stochastic- process models Mathematical Modeling - Nearly all of these techniques involve the construction of a model that attempts to capture the behavior of the system being studied Statistical methods Econometric methods Decision analysis
7
Analysis Modeling and Simulation Defined Analysis: Evaluating and assessing system performance, processes, and relationships to determine measures of importance such as effectiveness, performance, and reliability; typically using the results from models and simulations Modeling: Creating representations (models) of systems including their processes, behaviors, and interactions Simulation: Using (executing) models over time to investigate system performance
8
Model vs. Simulation Simulation - Execution of model over time Example: Simulating the Earths Rotation Model - Representation of the physical entity Example: Static Model of the Earth
9
Modeling and Simulation Allows the analyst to conduct trade studies and answer What if? questions Can assign values to the different model components and clarify the relationships among them Values can be altered to examine what may happen to the system under different circumstances. Inputs are modified and the model re-run to identify the best of levels for variables or combinations of design features

Demo CheapFoods Distribution Center
13
CheapFood Supermarkets has several stores in the St. Louis area. However, each is supplied from a different warehouse out of state. To cut costs, the owner of CheapFoods has decided to build a warehouse in the St. Louis area. CheapFoods Distribution Center
14
Ice Cream Meat Twinkies CheapFoods only sells three items. However, each has to travel on its own truck because of certain constraints. Requires freezer truck. Requires refrigerator truck and is perishable. Doesnt require special truck and lasts forever. Item Requirements: Supply Cost: 3x$ 2x$ 1x$ 1 2 3 Copyright©2006 Boeing. All Rights Resrved.

Great! Now, supply costs for the supermarkets are at a minimum. The owner can go home and buy that Ferrari hes been wanting and the operations engineer can go back to his desk. This was a VERY simplified example but it shows how a model can help provide insight into problem and identify a solution Problem Solved!

Life Cycle Cost/Total Ownership Cost Design to Cost Best Value Affordability Cost-Effectiveness Trades
20
Analysis of Alternatives Work with customer to identify design, configuration, or approach alternatives Evaluate operational effectiveness of each alternative Evaluate cost considerations for each alternative Compare cost and performance for each alternative Provide customers with insight to desired options Provide justification and support for selecting the preferred alternative
21
National Air Space - Wide Delay / Capacity Analysis for BCA Flight Operations Strategy Analysis of Alternatives
22
Statement of Problem and Alternatives Quantify, in terms of reduced system delays, the benefits of the alternative airport capacity- increasing concepts Alternative 1: Navigation improvements Alternative 2: Alternative 1 plus landing system improvements Alternative 3: Alternative 2 plus Air Traffic Control (ATC) improvements
23
Modeling Approach Boeing National Flow Model (NFM) National Air Space (NAS)-wide traffic analysis for a single day Simulation with a network of queues Queues for capacitated elements Input flight schedules and capacities Output delay statistics Directly addressed delay propagation NFM Network of Queues
24
Assumptions Used Current Market Outlook-based future schedule generation capability to analyze traffic levels for y2000, 2010, 2015, and 2020 Annualized results by taking the weighted average of six representative days Assumed no airline schedule re-planning, including no flight cancellations
25
Conclusion and Recommendations Successfully supported benefits analysis comparing the relative effectiveness of the alternatives ATC improvements (associated with Alt 3) were shown to have the greatest benefit The 20-25% capacity increases of Alt 3 are magnified into a 50% reduction in delays when confronted with y2020 traffic Better
26
Benefits to Stakeholders Methodology can be used to show how capacity increases translate to end-user benefits in terms of decreased delays Methodology is more credible than alternative approaches because it considers delay propagation, airport inter-dependencies and weather conditions correlated between airports Helps direct executive-level decision making in terms of which alternatives are most cost-effective to pursue Helps BCA to price avionics products Helps influence air traffic service providers to improve system performance so Boeing can sell more airplanes Provides analytical evidence of benefits that may be used in presentations to airline customers

NASA Cargo Processing for the Shuttle and Space Station Multi-Purpose Logistics Module (MPLM) Assembly Process
29
Statement of Problem With the elements of the International Space Station being delivered to Earth orbit, Multiple cargo missions were needed NASA experienced complex delays and problems in loading the MPLM and processing cargo for the Shuttle missions Needed to find the problem areas and test potential solutions
30
Potential Alternative Solutions Current process had not yet impacted a Shuttle launch date Excessive overtime and last minute heroics to meet schedule Either continue current process or find alternative Complete re-write of current procedures and processes at high cost Determine problem areas and test solutions
31
Modeling Approach Developed model to replicate current processes including current delay factors Used Monte Carlo to replicate process performance ranges Showed sensitivity of each process step to change and effect on overall process efficiency Tested potential changes in process and formulated course of action for correction
32
Conclusion and Recommendations Determined a 60% increase in efficiency to meet established schedules was possible Identified process areas to target and tested possible solutions Replicated new process changes Recommended four significant changes in cargo processing – low cost with high return Increased Efficiency Led to Boeing Win on Renewal of Cargo Processing Contract at Kennedy Space Center
