QL (“Quebec Lumber”) is a logging and wood processing firm in a remote part of the Canadian province of Quebec. They have recently acquired a remote track of timber that is located ten miles from their processing facility. Normally, this is not a problem as they are able to simply cut the timber and haul it using trucks to their processing facility. However, this track of forestland is ten miles to their north, and there are no roads connecting the tract of land to their facility. They have also acquired a narrow (120 foot wide) ten-mile strip of land connecting this tract of timber to their processing facility. QL considered building their own road between the two points, and have log trucks haul the logs to the processing facility. However, they have decided instead to go with a less expensive option, a narrow gauge railroad. The narrow gauge railroad would require the laying of ties and steel tracks, and will require a custom-built locomotive and rolling stock (train cars that will…

The sanitary landfill charges companies $200 per load and individuals $50 per load. On average, 90 companies tip their trucks each day at the landfill with a standard deviation of 30. There is time only for 110 deliveries in any combination of companies and individuals throughout the course of an eight-hour day. Company dump trucks enter through Gate A and individuals enter through Gate B. Individual demand is plentiful – often there are individuals turned away due to lack of capacity. It costs the landfill $30 to process a company dump truck and $15 to process an individual load. What is the expected profit for one day if the landfill allocates the optimal quantity of capacity to company trucks and individuals fill up the remainder of the сараcity? -

A new highway is to be constructed. Design A calls for a concrete pavement costing $80 per foot with a 20-year life; four paved ditches costing $3 per foot each; and two box culverts every mile, each costing $9,000 and having a 20-year life. Annual maintenance will cost $1,800 per mile; the culverts must be cleaned every five years at a cost of $350 each per mile. Design B calls for a bituminous pavement costing $55 per foot with a 10-year life; three sodded ditches costing $1.45 per foot each; and four pipe culverts every mile, each costing $2,100 and having a 10-year life. The replacement culverts will cost $2,350 each. Annual maintenance will cost $2,900 per mile; the culverts must be cleaned yearly at a cost of $215 each per mile; and the annual ditch maintenance will cost $1.35 per foot per ditch. Compare the two designs on the basis of equivalent worth per mile for a 20-year period. Find the most economical design on the basis of AW and PW if the MARR is 6% per…
