Hampshire Farms Family Campground is a locally operated campground on the west coast of Newfoundland. For many years it was a farming operation and has gradually been converted to a vibrant campground with many facilities for families to enjoy. The campground operates from the May 24th weekend until Thanksgiving weekend each year - 20 weeks in total (7 days a week). The July 1 weekend tends to be the start of the busy season. On this weekend travelers arrive at the registration desk at an average rate of 15 per hour; they wait in the single line for the first available staff member. The average time to service a traveler is 12 minutes. Each staff member earns $15/hour and traveler at the registration desk 'costs' $5/hour. Hampshire Farms provides firewood in bundles for their guests to purchase. The owners purchase firewood from a local supplier, with ordering costs of $50 per order and holding costs of $2.00 per bundle. Demand averages 500 bundles per day. Currently they purchase 500 bundles at a time from their supplier. The owners are considering utilizing forested unused land to produce their own firewood (with an appropriate reforestation plan). Based on their research, they have determined they have capacity to produce 800 bundles per day, and demand is 500 bundles per day. Setup costs of the machines to chop the wood into firewood is $25 and holding costs are $5 for the finished bundle. They are also considering making kindling in the firewood production facility when they are not making the firewood bundles. It would take quarter of a day for set up and half a day for production for kindling. Hampshire Farms is planning to expand for the next camping season. They have identified the activities and time frames for the project. However, because they are unable to work on the project during the winter months, they have a maximum of 24 weeks to complete the work. They also think that severe winter weather may impact this and they could have only 19 weeks to complete. The table below shows the activities and their duration as well as the weeks that could be crashed and the associated crashing cost.
