Speculative Demand Problem: Solved By Economic Game Theory!
By @AlgoBrain
What is the Speculative Demand Problem?
A Business has 2 Warehouses - 1 local and 1 offshore. The business speculates that there may be higher LOCAL demand than OFFSHORE demand for the same price of the stocked product at that particular time, and in anticipation of higher sales considers shipping stock from its offshore warehouse to its local base.
The penalty for the decision to ship is the payment of freight cost.
Questions Arising
Is the speculation worth it? Will there actually be better sales either way? Will shipping generate higher sales? or lower sales?
The Solution
The solution lies in the adoption of game theory in the form of the speculative demand game. We create a game to model the situation and play for a large number of rounds (say of the order of 10,000 - 100, 000 rounds) to converge at a conclusive result (ship or don't ship).
The Speculative Demand Game
In this 1-player game (the business is the player), the business plays the system. There are only 2 moves for the player (business) - ship or don't ship. In either case the player utilizes fixed resources - demand (local and offshore), stock (local and offshore), price (fixed) and freight cost (fixed penalty for shipping).
Note: Demand is expressed as a weight between 0 and 1
Move 1: Don't Ship
Total Sales = Price*(Local_Demand*Local_Stock + Offshore_Demand*Offshore_Stock)
Move 2: Ship
Total Sales = Price*Local_Demand*(Local_Stock + Offshore_Stock) - Freight
The speculation has value (a win) if for any round of the game one approach yields a greater result than the other. The games must be simulated and played very many times to converge at a definite result.
Demand is modeled as:
demand = lowest _demand + random(1 - lowest_demand)
if demand > 1 then demand = (1+lowest_demand*demand)/(demand - lowest_demand)
Stock is modeled as:
stock = base_stock + random(max_addition)
Of course, price and freight cost are fixed. The games must be played in a binary gaming program such as the Dimkpa Binary Game Engine.
If we assume the following parameters:
Price = $500
Base Stock = 10,000 units
Max stock addition = 5,000 units
Lowest demand = 5% of stock = 0.05
Freight cost = $10,000
Then after100,000 rounds of gaming, the Dimkpa Binary Game Engine produced the following results for the speculative demand game:
Game Summary - after 100000 rounds
----------------------------------------
total lost = 50120
lost GOAL = 50120
total WON = 49880
% LOST = 50.12 %
% LOST GOAL = 50.12 %
% WON = 49.88 %
% METHOD 1 PICKED = 50.137 %
% METHOD 2 PICKED = 49.863 %
% METHOD 1 WON = 50.1764234 %
% METHOD 2 WON = 49.8235766 %
% METHOD 1 LOST = 50.0977654 %
% METHOD 2 LOST = 49.9022346 %
% METHOD 1 LOST GOAL = 50.0977654 %
% METHOD 2 LOST GOAL = 49.9022346 %
----------------------------------------
INTERPRETATION:
After 100,000 games, there is a 49.88% chance that the speculation is viable; and a 50.12% chance that it is not viable. If the viability of the speculation is rejected, then either move should yield a similar result. Should the player decide to accept viability of the speculation, then:
MOVE 1: DON'T SHIP
WON: 50.1764234 % of 100,000 games
LOST: 50.0977654 % of 100,000 games
Won MORE times than lost.
MOVE 2: SHIP
WON: 49.8235766 % of 100,000 games
LOST: 49.9022346 % of 100,000 games
Won LESS times than lost.
VERDICT: DON'T SHIP.

Why You Should Simulate Your New Business Idea
Do you have a new business idea? Looking for a risk-free and cost-free way to evaluate BEFORE you invest? Then SIMULATION is the
answer.
What
is Simulation?
Simulation is when you design a profit model representing your new
business idea and subject it to computer
analysis to determine how productive it will be in the real world when it
is implemented.
Does
Simulation Work? Why does it Work?
Simulation
works
because you use the same variables and parameters (settings) as you would in
the real world and you subject your 'model', which represents your actual
business idea, to the same kind of scenarios that would apply in real life.
An
Example
Say you wanted to open a doughnut business and you have absolutely no idea how it will (or if
it will) work. You need to simulate (perform calculations by computer) to
determine how productive it will be. Here is the scheme:
A profit simulation works
by evaluating CLIENT SIDE, COMPANY SIDE, and JOB SIDE parameters as follows:
CLIENT
SIDE
How many types of doughnut
ordered per day (types_prod)
Average price of each doughnut (avg_price_prod)
Average number of doughnuts
ordered per day (avg_number_ppd)
Commission (total client payment)
per day (comm_pd) = (types_prod)*(avg_number_ppd)*(avg_price_prod)
COMPANY
SIDE
Working days per month (days_pm)
Internal costs per day -
power/machinery (int_costs_pd)
Operational costs per day (op_costs_pd)
Petty expenses per day (oth_exp_pd)
Company daily expenses (com_exp_pd)
= (int_costs_pd)+(op_costs_pd)+(oth_exp_pd)
JOB
SIDE
Staff to product ratio (staff_prod_ratio)
Average staff wage per hour (wage_ph)
Avg. hours to make product (avg_prod_time)
Total daily Job Cost (daily_job_cost)=
(types_prod)*(avg_number_ppd)*(avg_prod_time)*(wage_ph)/(staff_prod_ratio)
PROFIT PER MONTH = (days_pm)*[(comm_pd)
- [(com_exp_pd) + (daily_job_cost)]]
Which broken down completely
becomes:
Equation for simulating profit (above)
OK, now we have our profit simulation
model all set up – that’s the equation above! Now let’s test it to see if it
works.
Let’s say these are typical
values for the variables we need:
How many types of doughnut
ordered per day (types_prod) = 3
Average price of each doughnut
(avg_price_prod) = $12.50
Average number of doughnuts
ordered per day (avg_number_ppd) = 50
Working days per month (days_pm)
= 30
Internal costs per day -
power/machinery (int_costs_pd) = $30
Operational costs per day
(op_costs_pd) = $100
Petty expenses per day
(oth_exp_pd) = $50
Staff to product ratio
(staff_prod_ratio) = 1
Average staff wage per hour
(wage_ph) = $10.50
Avg. hours to make product
(avg_prod_time) = 0.5
Simply plug these values into the
simulation model to get the expected profit per month from this business.
What’s your answer?
$27,225
per
month. Now that’s a business I’d LOVE to get into!
Can you see why this is important?
Well, that's why you need the free profit simulation service from MDS
that takes this data and gives you a free simulation, so you can know how much
profit your new business idea will generate per month. Other analytics options
are also provided.

New Shape Discovered!
I discovered a new shape:-
Meet the Dimkpa Automaton:
Fig: 80-non-repeating Dimkpa Automaton (k=1.06) - smooth
Fig: 80-non-repeating Dimkpa Automaton (k=1.02) (smoothed out)
I know, it looks like a football!
Definition
The Dimkpa Automaton is the locus of a point moving in turns within a square such that it starts from the origin and is always projected at a constant angle.
Equation
The equation governing the Dimkpa Automaton is:
Turns
A turn is a unit of motion of the automaton; where it is initially projected from the origin or somewhere along the base of the square (along the x-axis) to “bounce off” the opposite square edge before bouncing off other edges to return to the base.
For K>1 it is called a non-repeating Dimkpa Automaton and it does not leave the imaginary square onto which it is projected. If K < 1 it becomes a repeating Dimkpa Automaton and may leave the boundaries of the square.
Relationship to other Known Shapes
If K = 0 it is a square. If K>>1 or K<<1 it is a spiral.
The (beautiful) examples above are non-repeating Dimkpa Automatons. The figure below shows what a 50-turn non-repeating Dimkpa Automaton looks like if it is not smoothed out (Its true shape):
Fig: 50-non-repeating Dimkpa Automaton (plain)
The expression above gives the Area of the Dimkpa Automaton.
I leave you with a picture of the first Dimkpa Automation ever created! It's a K=1 DA
