Batch production scheduling is the practice of planning and scheduling of batch manufacturing processes. Although scheduling may apply to traditionally continuous processes such as refining, [ 1 ] [ 2 ] it is especially important for batch processes such as those for pharmaceutical active ingredients, biotechnology processes and many specialty ...
Batch applications are still critical in most organizations in large part because many common business processes are amenable to batch processing. While online systems can also function when manual intervention is not desired, they are not typically optimized to perform high-volume, repetitive tasks.
Batch production is a method of manufacturing where the products are made as specified groups or amounts, within a time frame. A batch can go through a series of steps in a large manufacturing process to make the final desired product.
Scheduling and choosing the actual work to be started in the manufacturing facility" [1] Setting up and delivering production orders to production facilities. [5] In order to develop production plans, the production planner or production planning department needs to work closely together with the marketing department and sales department.
A job scheduler is a computer application for controlling unattended background program execution of jobs. [1] This is commonly called batch scheduling, as execution of non-interactive jobs is often called batch processing, though traditional job and batch are distinguished and contrasted; see that page for details.
Available-to-promise (ATP) is a business function that provides a response to customer order inquiries, based on resource availability. [1] It generates available quantities of the requested product, and delivery due dates. Therefore, ATP supports order promising and fulfillment, aiming to manage demand and match it to production plans.
All these factors contribute to long lead times, ultimately resulting in waste throughout the enterprise such as excessive forecasting, planning, scheduling, expediting, work in progress (WIP), finished goods costs and obsolescence. These increase the overall costs and lower the organization's competitiveness.
In computer science the problem of job shop scheduling is considered strongly NP-hard. In a job shop, product flow is twisted. A typical example would be a machine shop, which may make parts for local industrial machinery, farm machinery and implements, boats and ships, or even batches of specialized components for the aircraft industry.
