Background Darby Company manufactures and distributes meters used to measure electric power consumption. The company has production production plants in El Paso, Texas and San Bernardino, Bernardino, California. Californi a. The company also has three distribution distributio n centers in Fort Worth, Texas; Santa Fe, New Mexico; and Las Vegas, Nevada. Nevada. The company has nine customer customer zones that its product product is shipped to from the three distribution centers and they are; Dallas, San Antonio, Wichita, Kansas City, Denver, Salt Lake City, Phoenix, Los Angeles, and San Diego. objective Due to the rapid growth that Darby Company has experienced, the overall efficiency efficiency of our distribution system is being assessed to verify that Darby Company is maximizing its distribution distribution resources.

Version 3 costs $2 less per meter to ship than Version 1 or Recommendation Version 2 After a thorough analysis of the Darby Company distribution system, Version Version 3 of the distribution methods methods analyzed is the distribution distribution network that Darby Company should pursue to maximize its resources and minimize costs. We further recommend Darby not expand manufacturing manufacturing operations until its demand has grown to meet and exceed its supply capabilities.
Rationale
2
Should Darby choose to include some shipping directly from the manufacturer in its schedule, it will save $3480.00 in manufacturing costs as well as $67,236 in transportation costs at its current demand schedule. Darby also has the potential in save $2.00 in transportation costs per unit and, therefore, could face an additional potential savings of $17,480 as its demand increases, totaling a potential cost savings of $88,196. Further, Darby has the ability to meet an increase of demand up to 8740 units before it is forced to expand its manufacturing operations. If the cost of opening a new plant is an average near $2 million, and the costs of shipping up to 8740 additional units is approximately $120,000, Darby can save, $1.8 million by waiting to increase production. Managerial Report #1. If the company does not change its current current distribution strategy, what will its distribution costs be for the following quarter?

Transportation Transport ation costs will be reduced from version 1 to version 2 by $16,348. This is largely due to the lower production cost in San Bernardino passed on to the distribution center then onto the transportation cost. #3. The company wants to explore the possibility possibility of satisfying some of the customer demand directly from the production plants. In particular, the shipping cost is $0.30 per unit from San Bernardino to Los Angeles and $0.70 from San Bernardino to San Diego. The cost for direct shipments from El Paso to San Antonio is $3.50 per unit. Can distribution costs be further reduced by considering these direct plant to customer shipments?

#4. Over the next five years, Darby is anticipating moderate growth (5000 meters) to the North and West. Would you recommend that they consider consider plant expansion at this time?
Due to the fact that Darby is currently under-selling its current supply of 50,000 meters, it is not practical for Darby to expand its plant operations at this time. If the company grows by approximately approximately 5000 meters, there will still be a remaining portion of 3,740 of the supply remaining.
