The main difference between planning and scheduling is that planning determines what and how much should be done, while scheduling defines who and when operations will be performed. When an operations schedule is executed, each operation on the production path is scheduled for the resource that is specified for the operation. In addition, the duration of each operation is specified in the production route. If a resource group is specified for an operation, the schedule reserves capacity in the group.
However, unlike task scheduling, operations scheduling doesn't select specific resources for the group. If you are working with limited capacity, scheduling depends on the availability of resources needed to complete production. The operation schedule follows the sequence of operations specified in the production path. Programming reserves the capacity of resource groups, depending on the operating times defined in the production route.
The sum of the available capacity of the resources involved determines the capacity of the resource group. Capacity reserves that already exist for resources are considered unavailable capacity. If there is not enough capacity available for production, production orders may be delayed or even stopped. You can also specify the efficiency you expect from the resources involved in production.
Efficiency is specified as a percentage of the resource. The efficiency percentage adjusts the performance of the resource. This setting affects the time reserved for the resource. The delivery times of operations that use the resource are also adjusted accordingly.
Before starting any work, it is necessary to plan because, when things are well planned, the desired results can be achieved. The main components of operations programming are programming direction, resource capacity, and material optimization. The operations schedule also drives master planning and determines material requirement calculations. After executing the operations schedule, the status of the production order is Scheduled and all operations are scheduled in the order specified by the production route.
If you want to include more details in the schedule, such as information about current capacity, you can schedule tasks after executing the operations schedule. Unlike task scheduling, operations scheduling doesn't divide operations along the production path into tasks. In addition, depending on the type of design and work, such as the workshop, batch production or mass production, the techniques of programming systems differ. In the same way, in the case of production, it is important to plan in advance, since it provides us with the parameters to implement the control of activities and suggests if there are any discrepancies.
Production planning involves evaluating and determining the resources needed in the production process to achieve the intended objective. We use programming to plan the use of factory equipment and resources and also to define processes and the purchase of materials. It involves determining the schedule and order of the project's operations and its assembly to determine the total time for its completion. If you use master planning and multi-threaded operations scheduling, finite capacity will not be taken into account.
