Key words

  • Change from forecast to confirmed

  • Available to promise and free slack

  • Bottleneck process

  • Engineering changes / Re-engineering



In job-order production, a rough plan is formed at the inquiry stage, a delivery promise is made, and the order is received.

This production method is characterized by the facts that reengineering after order entry is required, and that engineering changes and process changes frequently occur during production.

This may cause a number of issues.

  • A veteran planner is often responsible for planning single handedly, which makes it difficult to properly take into account current loads.
  • The planner lacks the resources to perform progress management of projects currently in production and to re-plan according to engineering changes.
  • He devotes time to the projects whose due date is getting near, and as a result lateness frequently occurs.

Such a situation leads to opportunity losses and drops in customer satisfaction.


You can solve these problems by using the Asprova production scheduler, which allows you to carry out planning with high speed.

Title, summary, and total duration of each video
68.00 Introduction

Job-order production is a type of production wherein the product is engineered after the order is entered, and procurement to production and installation are managed.
We will describe the features of job-order production and the method of utilization of the production scheduler for this purpose based on the machining and assembly model.
68.01 Master data settings and finite capacity scheduling

We will explain about the required master and order information while creating an assembly process schedule.
You can create a plan by simply registering the master and order information and clicking a button.
68.02 Free slack and move time

In job-order production, delays may occur due to a variety of reasons such as engineering changes, so a reasonable margin of time is needed.
You can create a production schedule that takes into account free slack and wait time.
68.03 Finite capacity planning and manpower planning

The bottleneck processes in the assembly department are the final assembly process and the test process.
Finite capacity planning based on the number of machines and the number of workers is effective for processes that require planning accuracy, such as bottleneck processes.
68.04 Order details

The order Gantt chart allows you to easily grasp the overall plan and progress by allowing you to extract sales orders and their associated production orders.
The pegged order Gantt chart is useful if you want to check all the sales orders.
68.05 Make-to-stock production and job-order production

In the case of job-order production, the engineering work is carried out after order entry.
In the forecast stage, a standard product master is used to create a plan.
I will explain the change from forecast to confirmed, and the creation of the master for the confirmed order.
68.06 Relationship between machining plan and assembly plan

The schedule of machining process is created based on the assembly process schedule.
Because the assembly process input items are produced during the machining process, the assembly process schedule is handed to the machining process for scheduling.
68.07 Reflection of results and progress management

I will describe what to do with the production scheduler, taking the example a delay in the arrival of raw materials.
With Asprova, you can detect delivery delays due to a variety of factors, and quickly reflect measures such as free slack, production time and shift adjustments to the plan.
