Model sieciowy wykorzystania maszyn rolniczych przy wykonywaniu prac agrotechnicznych

Some of ways of reducing farm machines operating costs are rational machinery assemblage. composition and optimal farm jobs assignment. Optimization solution for this tasks can be done by solving network programing task. Relations between machines and field work lead to a relational database data model. A basic generalized network path of many machines working simultaneously is created and all quantitative dependencies are established. Depending on field work type three types of path are identified, and incorporated into final cumulative network model. This structure has served the author for optimization calculations on real empirical data, which can attest usefulness of the model.
