Default Battle of SDM - Spring 2019

With the massive syllabus changes, might as well get this thing underway now!

New 2019 syllabus here:https://www.soa.org/Files/Edu/2019/s...dm-syllabi.pdf

Date: Thursday, May 2, 2019

Good luck to all those tackling this exam.

Steve

I'm in. I took the Fall sitting off and I'm happy I did given the massive syllabus overhaul. It would've been devastating to fail the Fall sitting and have to take what almost looks like a entirely different exam based on the new syllabus readings.

Pros of the new syllabus:
  • Looks like they added some operations research material (optimization, simulations and decision modeling). OR has finally made its way back into the exams!
  • More textbook readings than article readings. I've found the textbooks to be easier to follow/connect to the objectives than the one-off articles

Cons of the new syllabus:
  • More accounting material
  • Emphasizing more general business skills than technical risk management skills

Time to get studying!

Yes, we do have more accounting material, but I believe it is a bit higher quality. SDM-100 left a bit to be desired, and I think what we have to replace it with is easier to follow.

And I completely agree with having textbooks being better! That makes it much easier to "get into the flow," since the chapters naturally build on themselves. With the article readings, the disjointed nature makes it hard to build a coherent internal "story" about what we are supposed to learn.

Overall, this was a really good overhaul, and SOA seems to be getting us back to what SDM is meant to be about.

One more downside with the new syllabus is losing Undoing Project -- it was a 300+ page book that could be reduced to 15 pages of concepts. The new books are definitely not so compressible!

But then again, some of the study notes lost are not going to be particularly missed.

Good Luck on your studying -- I know you will give 110%

I'm going to be that guy this sitting - the guy that you love and/or hate as they provide periodic unsolicited updates/cries for help on how their studying is going

This exam is final boss worthy. I feel like this syllabus dwarfs the CFE syllabus and requires you to sneakily remember a non-trivial amount of material from the ERM and CFE exams in addition to the mountain of SDM specific content and giant SDM case study.

If I'm going to one-punch pass this, I'm going to need to study like hell - 100 pages of reading a day, 100 flashcards a day, a full practice exam a day- all without the heater on in my apartment. I'll know I'm ready when my hair begins to fall out! (The last paragraph is a shameless One-Punch Man reference btw)

Awesome! This board has recently got a bit too quiet, and it looks like you will be a good antidote to that!

This exam is definitely a different beast than ERM and CFE. Glad you are starting to get a sense of that ... if you are looking for a strong opponent, this is one!

So you all know how Miami football has the turnover chain (https://www.youtube.com/watch?v=f4C6CsykCVI)?

This thread should have the value chain to celebrate studying and exam successes!

So I'm working my way through Data, Models, and Decisions and having tons of fun (like legit - I was really excited to see that there's OR material on this exam. I've always wanted to learn it.).

One of the things I'm doing to further my learning is coding the examples in R.

For instance, here's a shiny app for the Conley Fishing example in the simulation section of the book: https://cjh4fx.shinyapps.io/conley_fishery_app/

And here's the R code I wrote the New Bedford Steel linear optimization example:

install.packages('lpSolve')
library('lpSolve')

# Set up the problem: See page 327 in Data, Models, and Decisions

# Define the objective function
f.obj <- c(49.5, 50, 61, 63.5, 66.5, 71, 72.5,80)

# Define the constraint matrix (note that these values are the coefficients
# e.g. first row is A + B + C + D + E + F + G + H
# second row is A + B - C + D - E + F - G - H)
# diag(8) creates an 8x8 identity matrix
f.con <- matrix (c(1, 1, 1, 1, 1, 1, 1, 1,
1, 1,-1, 1,-1, 1,-1,-1,
0, 1, 0, 1, 1, 1, 0, 0,
1, 0, 1, 0, 0, 0, 1, 1,
-4,-3,-1,1, 2, 3, 4, 6,
diag(8),diag(8)), ncol=8, byrow=TRUE)

# Direction of the constraint
f.dir <- c("=", ">=", "<=", "<=", ">=",
"<=", "<=", "<=", "<=", "<=", "<=", "<=","<=",
">=", ">=", ">=",">=", ">=", ">=", ">=", ">=")

# Target value of the constraints
# rep(0,8) is the non-negativity constraint
f.rhs <- c(1225, 0, 720, 650, 0,
300, 600, 510, 655, 575, 680, 450, 490,
rep(0,8))

opt.coal<-lp ("min", f.obj, f.con, f.dir, f.rhs)

# Answers
#a)
opt.coal$solution
# 55 600 0 20 100 0 450 0
#b)
opt.coal$objval
# 73267.5
#c)
opt.coal$objval/1225

If you think you'd be interested in seeing other examples worked out - PM me. I'd love to share!

Brilliant - great active studying! ... and great sharing!

The other trick is to think about how this new stuff will be tested on the exam.

If you want, at some point, we can share ideas on questions ... I find developing SDM-level practice exam questions that best way to get really high pass rates on this exam.

So I'm almost at the point in my studying where I need to start tackling the Accounting for Decision Making and Control readings. Any tips from the experts?

Looking at you Paul and Steve.
