|The most efficient use of resources is
a goal for most industries, but especially capital
intensive industries such as pulp and paper. Efficient
utilisation of resources can be aided by smart scheduling
and optimisation of cost functions, to maximise
profitability without generating excessive work in
process, or inventory.
Scheduling Systems can be provided for short to medium term scheduling and simulation which determine the maximum plant production rate consistent with constraints on:
These systems are intended as an aid to production coordinators, and operators, to determine the most appropriate production rates which maximise production and minimise production rate changes.
A model of the process is built graphically to define the system. With no limiting constraints, the system model will calculate production rates to achieve and maintain the levels in the intermediate storages that will best cope with unplanned shuts upstream or downstream of each storage.
If the production rates required to match product demand are outside of minimum or maximum production ranges, best use will be made of the available capacity in the intermediate storages to maintain production.
If production is limited by raw material supply or effluent handling throughput, the maximum production rate is calculated according to the available raw material.
The Pro-Plan Process Scheduling System is based on the following philosophy:
Improved scheduling will result in less shutdowns due to storage capacity constraints - and consequently greater plant throughput over time.
