A certain city the Transportation Authority (CTA) has trollies leaving
regularly throughout the day beginning at 5:00 a.m. Although the
length of a trip and the number of stops are constant, the time taken for
each trip varies due to weather, traffiffiffic, and time of the day. According
to the CTA, the mean time taken for the trip is 50 minutes. Suppose
the travel time is Normally distributed with standard deviation σ = 4
minutes. A random sample of 25 trips is obtained, and the time for
each is recorded.
Find the probability that the sample mean time will be less than 48
minutes.
Is transportation modeling a type of linear programming? Justify your answer
BETTER PRODUCTS COMPANY has decided to start manufacturing four new products in three plants that currently have excess production capacity. The products require comparable production effort per unit, so the available production capacity in the plants is measured by the number of units of any product that can be manufactured per day.
a)Formulate this problem as a transportation problem by constructing the appropriate parameter table.
I already have an optimal solution (it's from the book). (I dont understand)-------------------------------------------------------------------------OPTIMAL SOLUTION:It has basic variables (assignments) X₁₂ = 30, X₁₃ = 30, X₁₅ = 15, X₂₄ = 15, X₂₅ = 60, X₃₁ = 20 and X₃₄ = 25, so that:
Plant 1 produces all of products 2 and 3.Plant 2 produces 37.5% of product 4.Plant 3 produces 62.5% of product 4 and all of product 1.
The total cost of Z = $3 260 per day.-------------------------------------------------------------------------Instructions:Please explain this…

That is an interesting question. Suppose that you analyze this simple transportation problem using the probit model. The variables in the model are defined as follows: autotime commute time via auto, minutes commute time via bus, minutes =(bus time - auto time)/10, 10 minute units = 1 if auto chosen bustime dtime auto The probit model you estimate is P(AUTO = 1) = ¤(ß1 + B2DTIME). The estimates of the parameters are: -0.0788 + 0.400DTIME. The marginal effect of increasing public (bus) transportation time, given that travel via public transportation currently takes 15 minutes longer than auto travel is A) 0.348 B) 0.139 C) 0.307 D) 0.123 E) None of the above (A, B, C, D) is close to be correct.arrow_forwardA fertilizer manufacturer has to fulfill supply contracts to its two main customers (650 tons to Customer A and 800 tons to Customer B). It can meet this demand by shipping existing inventory from any of its three warehouses. Warehouse 1 has 400 tons of inventory onhand, Warehouse 2 (W2) has 500 tons, and Warehouse 3 (W3) has 600 tons. The company would like to arrange the shipping for the lowest cost possible, where the per-ton transit costs are as follows: W 1 W 2 W 3 $7.50 $6.75 $6.25 $7.00 $6.50 $8.00 Customer A Customer B Write the objective function and the constraint in equations. Let V;= tons shipped to customer i from warehouse j, and so on. For example, VA1 = tons shipped to customer A from warehouse W1.

- eBook Problem 10-31 A long-distance telephone company uses a fiber-optic network to transmit phone calls and other information between locations. Calls are carried through cable lines and switching nodes. A portion of the company's transmission network is shown here. The numbers above each arc show the capacity in thousands of messages that can be transmitted over that branch of the network. To keep up with the volume of information transmitted between origin and destination points, use the network to determine the maximum number of messages that may be sent from a city located at node 1 to a oty located at node 7. 3 Maximum number of messages -arrow_forwardMorgan Trucking Company operates a special pickup and delivery service between Chicago and six other cities located in a four-state area. When Morgan receives a request for service, it dispatches a truck from Chicago to the city requesting service as soon as possible. With both fast service and minimum travel costs as objectives for Morgan, it is important that the dispatched truck take the shortest route from Chicago to the specified city. Assume that the following network (not drawn to scale) with distances given in miles represents the highway network for this problem.

If the product is 8 hours or more late, the penalty is $500. Shipping costs decline at a rate of $50 for each additional hour of transit time allowed. 1. What is the optimal delivery time (y) that will minimize costs? - 33.2 hours - 31.2 hours - 32.2 hours - 30.2 hours - 34.2 hours - 35.2 hours 2. If the product is delivered in 34 hours, what is the Taguchi Loss Cost (L)? - $250 - $300 - $80 - $500 - $0 - $125 - $375 3. If the product is delivered in 36 hours, what is the Total Cost (Taguchi Loss Cost plus Process Cost)? - $2,700 - $2,681.25 - $2,400 - $2,396.75 - $2,250.30 - $2,543.50arrow_forward
