Answer

Understanding waiting in line or lines and learning how to oversee them is one of the most critical ranges in operations administration. It is essential to create the plan, work plan, inventory levels, etc. Each day, we hold up in line in our benefit economy, from driving to work to checking out at the general store. In brief, holding up lines is unavoidable.

Question:Bindley Corporation has a one-year contract to supply motors for all washing machines produced by Rinso Ltd. Rinso manufactures the washers at four locations around the country: New York, Fort Worth, San Diego, and Minneapolis. Plans call for the following numbers of washing machines to be produced at each location:

New York

50000

Fort Worth

70000

San Diego

60000

Minneapolis

80000

Bindley has three plants that can produce the motors. The plants and production capacities are

Boulder

100000

Macon

100000

Gary

150000

Due to varying production and transportation costs, the profit Bindley earns on every 1,000 units depends on where they were produced and where they were shipped. Thefollowing table gives the accounting department estimates of the dollar profit per unit. (Shipment will be made in lots of 1,000.)
