Zheng. 2008. Modeling Multi-Objective Multi-Stakeholder Decisions: A Case-Exercise Approach. INFORMS Transactions on Education 8(3) 103-114, (http://ite.pubs.informs.org/, http://pubsonline.informs.org/doi/abs/10.1287/ited.1080.0012 supplemental files: HomeDepotTeachingNote.pdf (for instructors), Excel file. Files also at 25 http://faculty.sites.uci.edu/lrkeller/classes/ Background Home Depot proposed to open a retail building supply store in San Juan Capistrano, California USA The new store would be on 15 acres in a strip of industrial land. Home Depot owned two acres of this land. The rest of the land was owned by the city, and would need to be bought. 26 Background • The city would get $9 Million if it sells Home Depot the 13 acres. • Many were concerned that a “big box store” would destroy its historical small town feeling. • Nearby residents also worry that a Home Depot would cause traffic jams, pollute the air, produce noise and block ocean breezes. 27 Home Depot Case Alternatives Build Home Depot Don’t develop the land Build a recreational vehicle park Build specialty retail facilities Stakeholders (assign 6 student groups) City of San Juan Capistrano Competing Local Small Businesses Complementary Local Small Businesses Home Depot Nearby Residents Other Area Residents 28 Case Instructions • Ask the groups to: – Brainstorm the objectives of the stakeholder. Create a hierarchy of objectives by grouping related objectives. – Put the objectives in the spreadsheet. – Rate the options’ performance on each objective on a scale from 0 to 10. – Make their own judgment of the “raw swing weights” to put on the lowest level objectives. – Answer questions and determine the best option based on the analysis. – Post completed spreadsheet file to share. 29 Spreadsheet Structure for Each Stakeholder Questions for the City of San Juan Capistrano The City of San Juan Capistrano A. Brainstorm what the objectives of the City of San Juan Capistrano would be. To save time, finish ONLY the corresponding Excel spreadsheet for the city. Fill in the objectives on the spreadsheet. 10 9 8 B. Rate the options’ performance on each objective on a scale from 0 to 10, with 10 best. 7 6 5 4 3 2 1 0 C. Make your own judgment of the “raw swing weights” to put on the lowest level objectives. D. You can use the slider to adjust the raw swing weights assigned to each lowest level objective. (Note: Do not use the slider until you fill out the corresponding lowest level objective in the same row.) E. Calculate the overall value of each option. F. A bar graph based on the overall value of each option and a partial hierarchical tree of the objectives for the City of San Juan Capistrano will be created automatically on the bottom of the spreadsheet when your group completes all the steps above. Option 1 "Build Home Depot" G. Is there an option which is dominated (which is worse than one other “dominating” option on each objective)? Option 2 "Don't develop Option 3 "Build RV Park" Option 4 "Build specialty the land" retail" overall values H. Save the completed spreadsheet file under the name of “CityofSanJuanCapistrano” and post/email it to our course’s discussion forum. Choose one person to report your results orally to the class.

Andy Grove’s Prostate Cancer In the fall of 1994, Andy Grove- the former CEO of Intel- was faced with a difficult problem to solve. Initially, he was presented with an abnormal screening PSA (Prostate Specific Antigen) test that could represent the presence of cancer. His first reaction was to ask what to do with that information. At this point, he may or may not have had cancer. So, to better define if there was a required decision, he chose to gather further information. Some basic facts he obtained gave him a first understanding of the probabilities and outcomes he might face, finding that 200,000 men were diagnosed with prostate cancer in 1994 and that 38,000 would be expected to die, making prostate cancer the second leading cause of cancer deaths in men. Since his PSA result was just over the upper limit of normal, he elected to repeat the test in early 1995 in case his results were within the error margin of the test. The results suggested more strongly the presence of a tumor and he visualized a sugar-cube-sized tumor in his prostate. These tests results convinced him of the need to see the urologist for a biopsy to define if the test result was a true positive or a false positive. 48 Andy Grove’s Prostate Cancer The biopsy results indicated his PSA result was a true positive. He did have prostate cancer. This led to the formulation of his decision problem. What type of treatment should Mr. Grove pursue for treatment of his prostate cancer? There appeared to be four main decision alternatives. One option was to have the tumor and prostate gland surgically removed. This alternative can increase the survival rate and decrease the recurrence rate as well, however it will lead to a greater chance of being impotent after the surgery. Another alternative was to receive radiation treatments in the form of “seed” implantation to destroy the cancer cells. This option can increase the survival rate, but it also has serious side effects. A third alternative was cryosurgery, or freezing the tumor cells. Regarding this option, there was not enough information available to make an informed decision. The last option was to do nothing, taking the “wait and see” approach, which also carried much risk of losing his life if the cancer grew very quickly. Apparently, none of these alternatives was perfect. Furthermore, several other stakeholders were also very concerned with Andy Grove’s situation. Andy’s dilemma will be modeled as a multi-stakeholder decision problem. Those stakeholders are: Andy Grove, Urologist, Oncologist, Andy’s Family/Wife and Andy’s Company – Intel This case was written by L. Robin Keller and Tianjun Feng, of the UCI MSB, building upon the article by Andy Grove published in Fortune (1996), several case study reports by UCI HCEMBA students: L. Jeff Koh, Kenneth Rich, Suehei Lee, H. Ena Leo and others. See TAKING ON PROSTATE CANCER by Andy Grove with reporter associate Bethany McLean, FORTUNE, May 13, 1996. 49 Andy Grove’s Prostate Cancer • Divide into 5 groups. • For your stakeholder group, rate each alternative on each objective. • Determine weights on objectives. • Compute the overall weighted score for each alternative. • Andy Grove Case Excel file at http://faculty.sites.uci.edu/lrkeller/classes/ 50 Added background info. on this talk Talk Abstract Many know about the use of decision analysis to decide among alternative investments (such as pharmacological research and development) using decision trees with chance nodes to compute expected monetary value of different alternatives. Such an analysis aims to maximize a single evaluation measure for a single decision maker. We demonstrate less widely known decision analysis techniques using spreadsheet models of the multiple objective perspectives of the decision stakeholders. We show how to teach students to analyze real-life decision problems using case examples and discuss specific skills students are expected to learn, such as dynamic sensitivity analysis using sliders in Excel on objectives’ weights, and typical student questions and errors during case discussion. 51 Talk Abstract, continued Taught in business courses for both MBAs (including health care executive MBAs) and undergraduates. Sometimes, one objectives hierarchy is suitable for a set of stakeholders, and differences in opinions across stakeholders can be characterized by differences in the multiple objectives’ weights: -Merger of the Operations Research Society of America & The Institute of Management Sciences (INFORMS) -Protection against radioactive iodine in nuclear incidents 52 Talk Abstract, continued In other cases, an objectives hierarchy will be constructed for each stakeholder because their objectives are so different that construction of separate hierarchies better represents their divergent perspectives. -Tuna fish supplier source selection decision (StarKist, environmentalists, San Diego tuna fishing fleet) -Siting of a new Home Depot building supply store -Prostate cancer treatment decision (former Intel CEO Andy Grove, his family, company, doctors) 53 Keeney’s Professional Objectives Maximize the contribution of professional activities to… my quality of life Max. enjoyment Max. learning Provide service Enhance professional career Max. economic gain Build good professional relationships Min. the time required Min. time required where I live Min. time required away from home 54 Keeney (1992), Value Focused Thinking Objectives for Keeney’s son’s name 1.

No Compute Overall Values of Alternatives Yes Develop the Objectives Hierarchy Make the Recommendations Conduct Dynamic Sensitivity Analysis Using Sliders in Excel 58 Teaching Notes: Skills Students Can Learn Learn to assign value ratings to how well each option satisfies each objective Learn to creatively generate objectives and structure them into a hierarchy of objectives Learn to use the swing weight approach to generate importance weights on objectives 59 Teaching Notes: Skills Students Can Learn Learn to do sensitivity analysis in decisions under certainty, using “sliders” created in the Excel software. Learn to compare the overall values of options, using the sumproduct function in Excel. Learn to compare and contrast results from different stakeholder groups. 60 Teaching Notes: Typical Student Questions & Errors Students might not understand the difference between ratings and weights. The same weights assigned to different subobjectives are allowed. Students might generate wrong or redundant subobjectives for one specific objective. Students questioned whether they should start with the lowest or highest level subobjectives when computing swing weights. 61 Case Objectives and Pedagogical Benefits • Enrich the content of the typical undergraduate/masters level decision analysis or management science course – Focus on multi-objective multi-stakeholder decisions – Link creative problem structuring with analytical tool • Introduce the methodology to the students – In-class exercises and/or homework – Decision making tool to tackle real-life context-rich decision problems – Applied to corporate strategic decision making for a facility location problem 62 Stakeholders • The city of San Juan Capistrano: interested in the potential revenue, but concerned with interests of multiple stakeholders • Competing local small businesses: will be influenced by the arrival of Home Depot in terms of profit, etc. • Complementary local small businesses: will definitely be affected in terms of profit, etc. • Home Depot • Nearby residents: concerned with the possible adverse impacts on their quality of life • Other area residents: will enjoy the convenience, but may suffer from the possible increased traffic flow 63 1.1 Maintain efficient use of funds 1.
