Question
problem 4 please
Draw a project network for a Happy Smart Phone training program including the start and the end. What is the critical path, and minimum time to complete the project? Happy CEO is considering investing some money that was inherited. The following table gives the profits that would be realized during the next year for three different options? What is the maximax, maximin, equally-likely, minimax regret solutions? What is the solution, if there is 0.60 probability of a Good Economy? Happy says that worldwide internet ad revenues are given a $10B(Year 1), $13B (Year 2), $17B (Year 3). Please forecast the "Year 4" value using a 3-year moving average? Do the same for exponential smoothing starting with a Year 1 initial forecast of $10B, and an Alpha of 0.4. Also, forecast the "Year 4" value using a linear trend line. Stock price of the Happy stock is currently $41 per share. The following probability distribution shows how the price per share is expected to change over a one-month period. Using random numbers 0.1091, 0.9407, 0.1941, 0.8083 simulate the price per share for the next four months. What is the final simulated price per share? Happy Smart Phone has a product that shows a constant annual demand of 30,000 units. Each unit cost Happy 56. Ordering cost are $10 per order and the bolding costs are 10% of the value of the inventory. Happy has 365 working days per year, and the lead-time is 5 days. Identify the Economic Order Quantity, the reorder point, number of orders per year, ordering cycle time, and the total annual inventorying cost.
Explanation / Answer
Given the probability table :
Change probability cumulative prob range
-1. 0.15 0.15 0-0.1499
0. 0.25. 0.4. 0.15 - 0.39999
+1. 0.3. 0.7. 0.4 -0.69999
+2. 0.3. 1. 0.7 -0.99999
Hence
1st month = 0.1091probability = current +/- change = 41-1 =$40
2nd month =0.9407 probability = 40+2 =42$
3rd month = 0.1941 probability = 42+0= 42$
4th month = 0.8083 probability = 42+2 =$44
