Abstract : This report describes a computer program entitled 'Simulation for Harvesting of Aquatic Plants (SHAP),' and provides instructions and guidelines in planning for mechanical harvesting of plant-infested areas. The model provides a stochastic simulation that evaluates the harvesting system. SHAP utilizes linear programming theory for network flow analysis and queuing theory and is designed for using minimal input data in a conversational manner; that is, the user interacts directly with the program and receives output immediately. The model has been verified using field data collection records. The terrain subroutine organizes irregularly shaped plant-infested areas to be harvested into a distance-flow network (grid). The harvesting subroutine directs the harvesting procedure., The harvester (Aqua- Trio Equipment Co.) mows the aquatic plants; the transporter loads the plants and takes them to the conveyor located on the shoreline. The plants are then transferred from the transporter, via the conveyor, onto a dump truck for disposal at a convenient location. When the mowing, transporting, and disposal operations area complete, the statistics of time and queing operations for each component are computed. Operational costs are complied for each component (default 1977 dollars), including labor, supplies, and power costs required by the harvesting system. No prior experience with computer programming is required since all commands necessary to use SHAP are presented in this report. (Author)
