Production Model | Projective Solutions

By: Projective Solutions  09-12-2011

The Production Model lies at the heart of a Projective scheduling system.  This model details the physical workings of the plant including operating rules, product routings, process times, materials and resource requirements.  Constraints such as lot sizing, resource shift patterns, batch constraints, travel/transfer times, and setup considerations are captured in detailed knowledge tables.

The Production Model is validated against historical production data to ensure that the system accurately depicts the capabilities of the plant. This ensures that the resultant schedules are realistic at the shop-floor or process level.

The Production Model can be developed using one of several techniques, depending on what is most appropriate for the problem at hand.  Methodologies available include:

  • Discrete-event simulation modeling
  • Constraint-based modeling
  • Mathematical model formulation

In some cases, a discrete-event simulation model reflecting plant operations  and constraints may be a secondary output of the development process.  This model can be used in an offline capacity for what-if scenario analysis and process improvement projects.

Other products and services from Projective Solutions


User Interface | Projective Solutions

Our interface allows your team to work with the plan, modifying and testing based on your experiences, and manually overriding it in the case of unexpected situations. These tools can support multiple users spread throughout different departments and facilities, providing a valuable communication and collaboration tool.


Planning Engine | Projective Solutions

Projective typically provides weighted planning routines to allow the end user to test multiple plans and adjust planning methods based on current business conditions. Our consultants draw on the knowledge of your planning team and a library of optimization techniques and heuristics to design routines specific to your processes.


Data and Integration | Projective Solutions

Projective’s development teams are experienced with several database platforms and will build your application database using whichever is currently in use within your business. These data links are typically triggered on-demand by the planning team, but can also be configured to work in real-time or based on timed updates.


Scheduling | Projective Solutions

The pages in this section detail the Projective approach to Scheduling problems, building upon the four quadrants of the Projective toolkit; Production Model, Scheduling Engine, Data & Integration, and User Interface. Projective Scheduling Solutions generate detailed, station or machine-specific schedules on a minute-by-minute basis that consider performance at both the station and facility level.


Capacity Model | Projective Solutions

This model is developed prior to the start of any planning efforts, providing the project teams with invaluable insight into how the overall system actually works. The Capacity Model is an integral part of Projective’s planning systems, capturing the detailed workings of the process. The completed Capacity Model is used as a base for development of the Planning Engine.


Solutions | Projective Solutions

Detailed, minute-by-minute schedules by machine or production centers, including all relevant details on changeover times, downtimes, machine settings, and resource requirements. Applications: Allocating orders to multiple facilities; planning raw material requirements based on current order forecast. Scope: Generally include a wide process view, considered at a somewhat limited level of detail.
