SUBJECT AREAS: computer science, math
CONCEPT: A computer can save a business time and money.
OBJECTIVE: Students will develop a working model computer program of a recycling center which can be used to make decisions about a school recycling program.
*computer and manual
*information from school recycling coordinator
KEYWORDS: material management
BACKGROUND: A recycling center has three suboperations for which computer programs should be developed. These suboperations are:
1. material management at the recycling site,
2. work schedules during the hours of operation at the recycling site, and
3. the business finances of running the recycling center.
Material management - This aspect involves:
a. the quantity of materials being generated,
b. the size of the containers and the volume/mass they will hold at the school's recycling site, and
c. the scheduling of pickup and transportation of materials to the local private recycler.
Work schedules - This aspect could involve:
a. scheduling individuals to perform the following tasks - breaking glass, cleanup, separating materials, tieing and stacking newspapers (depending on requirements of local markets), closing up the school center, etc.
b. providing a schedule for pickup of recyclables,
c. providing the appropriate number of workers for peak periods.
Business finances - This aspect involves:
a. monitoring the income, expenses, and earnings of the program,
b. distributing the earnings to the various organizations involved in running the school center.
NOTE: Most programs will not make a profit if time and set-up costs are considered, but there are avoided costs such as reduced tipping fees at the landfill or incinerator because of lowered volumes of trash.
1. Raw data involving the three aspects mentioned above must be obtained from the individual operating the school center. Once the data are obtained, the programs should be developed and continually modified to accurately reflect the operation of the recycling center.
2. Daily or weekly entries should be made in the program to keep track of the center's operations.
3. Periodic printouts of the three aspects of the center should be made available to the individuals in charge of running the recycling center. The information provided will enable them to make sound decisions concerning the center's operations.
List three operations involved in a school recycling center which might be efficiently handled by a computer program.
Who could develop and process a computer program for a recycling center in your school?
Once a computer program for a recycling center has been established, estimate the savings in time to operate the center.
