Find an initial solution and total cost of the transportation problem in Table 5(b) by using North-west corner method and Vogel's method.
Table 5(b)
The ELECTROCOMP corporation manufactures two electrical products: air conditioners and large fans. The assembly process is similar in requiring certain amount of wiring and drilling. Each air conditioner takes 3 hours of wiring and 2 hours of drilling. Each fan must go through 2 hours of wiring and 1 hour of drilling. During the next production period, 240 hours of wiring time are available and up to 140 hours of drilling time may be used. Each air conditioner sold yields a profit of 25.Eachfanmaybesoldfora25. Each fan may be sold for a25.Eachfanmaybesoldfora15 profit. Formulate and solve this LP production mix situation, and find the best combination of air conditioners and fans that yields the higher profit.
Find an initial solution and total cost of the transportation problem in Table 5(b) (i) by using Vogel's method, (ii) by lowest cost method
What is supply chain and supply chain management (SCM)? What are main objectives of SCM?
What are the four main reasons why reverse engineering is used?
For the following Karen-Reifsteck Corp. data, find the starting solution and initial cost using the Vogel's method.
Wheat is harvested in the Midwest and stored in grain elevators in three different cities (Kansas city, Omaha and Des Moines), supply three flour mills, located in three other cities (Chicago, St. Louis, and Cincinnati). The following Table summarizes factory availabilities, projected store demands and unit shipping costs.
Use the north-west corner method to find out the total cost.
Wilkerson printing has four jobs waiting to be run this morning. Fortunately, they have four printing presses available. However, the presses are of different vintage and operate at different speeds. The approximate times (in minutes) required to process each job on each press are given in bellow Table. Assign jobs to presses to minimize the press running times.
