The production schedule may be prepared manually, semi-automatically or automatically. The complexity of VENDO.ERP, cohesion of cooperating modules and access to data stored in them enable maximum use of information stored in the system and ensure high level of scheduling automation.
The quality of the prepared schedule largely depends on the data used as its basis.
Continuous recording of production progress is extremely important from the point of view of efficiency and effectiveness of the prepared schedule. The recorded data allow the accepted schedule to be updated, provide information on the actual condition of order execution and ensure control over every stage of the production process. This is particularly important if unplanned events occur, not included in the schedule and influencing its further execution.
Forward scheduling – The goal of this strategy is to determine the start and the end dates for production operations, with the former date used as the initial value. In this case, the sorting algorithm starts ordering production operations starting from the date specified as the start date for order execution.
Backward scheduling – The goal here is to determine the start date for the first production operation, with the end date for the entire order used as the input date. In order to achieve this goal, we need to thoroughly specify the duration of individual operations taking into account availability of individual resources and breaks and standstills planned during the operations. The probability of other, unplanned events potentially influencing the actual order execution time should also be taken into account.
Prepared production schedules are presented as interactive Gantt graphs. This is a simple and transparent method of presenting:
may be fast, easy and efficient. Reliable data preparation and overseeing its continuous updates is a required condition. The adequately high quality of processed data and its conformity with the actual state of affairs guarantee the adequately high quality of the prepared schedule and increase the chance of executing the order according to the accepted schedule.
