SELECTED EXCEL DEVELOPMENT PROJECT

Production & Machine Scheduler

A macro-driven Excel production system that schedules jobs by machine and hour. The VBA contains logic to insert a task into an already occupied machine, shift following jobs and update the underlying TASKS records—not simply recolor a timetable.

THE KEY AUTOMATION

What happens when a machine is already booked?

A new order can affect every job queued behind it. Instead of manually editing dozens of dates, the workbook includes VBA routines designed to manage those related changes.

Choose a machine and job

Select a customer, part, processing step, machine, quantity and desired starting time.

Inspect occupied time

The add / modify routines inspect jobs already assigned to the selected machine and handle insertion paths.

Recalculate subsequent work

For affected jobs, VBA calculates revised start and finish times and updates records in the TASKS table.

Rebuild the daily board

A separate macro renders the machine-by-hour schedule, colored priority blocks and job details.

ACTUAL EXCEL SCREENS

The scheduling workflow, screen by screen

These are the uploaded workbook screenshots, not browser simulations. The top-level machine board already contains example jobs; the forms show how those jobs can be registered or modified.

Daily machine board

Machines appear as columns and scheduled hours as rows. Green, yellow and red work blocks make job allocations visible at a glance.

Add a production task

Register customer, part, step, quantity, start, priority and machine. VBA handles database insertion and scheduling calculations.

Modify an existing task

Change a job assignment or timing from the dedicated form. The workbook includes code to adjust impacted schedules.

Configure customer and part

Define part processing steps and setup times for reuse by the machine scheduling system. This original screenshot shows an empty input form.

INSIDE THE WORKBOOK

More than a timetable

The workbook combines a machine database, configurable part steps, task entry, priority settings, scheduling calculations, date navigation and completed-task history.

Production records

The TASKS table contains job IDs, customer, part, quantities, work steps, assigned machine and date/time fields.

Planning tools

Dedicated forms for adding, modifying and archiving tasks reduce manual edits to the underlying database.

Operational visibility

Visual blocks make machine workload, priorities and available hours easier to review.

Scope and verification

These capabilities were checked in the supplied macro source. The VBA was not executed in Excel during this website build, and some scheduling edge cases (including rollover and overlapping time ranges) still require operational testing. The screenshots contain example production jobs.
