Origin of Scheduling

Scheduling has been an everyday thing to the common man—for work and other personal activities. It’s now a thing that we automatically do for its mandatory significance to everyone. After all, we live in a fast-paced world. Without a schedule, things might get a little bit chaotic.

We can only assume that scheduling started since time began; for without time, there will be nothing to schedule. The very point of scheduling is to do things in an orderly, timely manner. Time is an essence whose beginning cannot be empirically proven—yet. It would be very hard to know the exact origin of scheduling because it is an innate human ability. If we fly light years to the modern era, the art of scheduling can be traced back to the invention of the bar chart, one of the most common tools for scheduling. Many credit the bar chart invention to William Playfair (1759 – 1823), the Scottish Engineer and political economist who founded the graphical method of statistics; however, there is still much to uncover because of some discoveries with regards to early writings that use charts that are somewhat similar to the bar chart.

The Gantt chart

In 1910, a man named Henry Gantt developed a bar chart that illustrates a project schedule.
These charts contain information such as the beginning and end dates of the so-called terminal / summary elements of a project. This, of course, consists of the work breakdown structure, generally defined as “a deliverable oriented decomposition of a project into smaller components.”

Modern Scheduling for Production

Throughout the years, with the advent of computers and different types of software, scheduling has been made easy. For manufacturers who handle big amounts of data, this might not be the case as some relied on hand-to-paper scheduling and other software that are not specifically designed for production scheduling.

Then, as man furthered his knowledge in scheduling, a manufacturing process called Advanced Planning and Scheduling (commonly referred to as APS or advanced manufacturing) was developed. To define it simply, APS is a management process “by which raw materials and production capacity are optimally allocated to meet demand.” If one talks about efficiency in production scheduling, APS is the key to success. There’s a lot of software that are specifically developed for APS. Asprova, the leading APS solution provider in Japan characterizes the Production Scheduler as something that “creates production schedules quickly for multiple items and multiple processes, realize visualized management, even shorten lead times, reduce inventory, enhance delivery rate, and increase customer profit.”
