GPS^® 64bit

Planning system of materials and resources with finite capacity.

 

The business goals are increasingly demanding, both in terms of products and services. It is neccessary to define the delivery dates in a reliable way and constantly test them.

Planning systems are able to support companies effectively and timely in these challenges.

 

GPS^® is a system that, starting with MRP II methodologies:

• has innovative techniques to reallocate in time (forward planning) critical events and all others it constrian.

• highlights the time-unreachable goals, delays, and all other events that help create the problem.

• integrates with all the management systems from which receives the data.
• is available on different platforms (IBM Mainframe, AS/400, iSeries, Unix, Windows).

 

The Modules

 

GPS 64b is enriched with new modules, based on its own tecniques of operations research, which allow a better use of materials and resources optimizing this way the production plans.

 

 

  

GPS^® MAO

Material Allocation Optimization

To successfully launch into production is important to check beforehand the availability of parts and allocate stock to production events which require them, and take into account their completeness for each order.

This task is further complicated in the presence of multilevel BOM in case you want to focus on the assignment of materials to all of the oreders that are able to go through, through the chain of posts until the finished products, therefore reducing material stocks in process.

 

The use of traditional applications, which use heuristics based on the destination of materials by priority or requested date, very often lead to unsatisfactory results because they are not able to find the optimal solution that identifies the most "feasible" orders.

The MAO module is able to allocate component stocks to orders in order to maximize its use.

There is also a MAO version that integrates with PRM (Pegging Relationship Management) in order to successfully create target bonds (pegging) for those orders to which stock was allocated. This serves to homogenize the planning process within the RCP (Raw Capacity Planning) module.

GPS^® SRP 

Surplus Reduction Planning

Every planning system, even if based on MRP (Material Riquirment Planning) techniques, can generate stock of components and/or semi-finished products which are then not used, not required by the orders.
This situation, for different reasons can generate:
Production plans cancellation or modification, customer orders cancellation or modification, batching parameters with which the system was modeled (minimum and multiple quantities), scrap or increased rates to take account of the production efficiencies.

SRP responds to the need of identifying the unrequired stock, to enhance it, and by analyzing the companies BOMs, to propose orders of production and of purchase for realizing finished products using the remaining materials.
At the same time, the stock reduction value, the purchase cost and the production cost of com ponents, needed to complete the product, are highlighted for each finished product batch.

The parameters and the filters on which the process is based, are set by the user (type of finished product to consider for minimum and maximum, maximum cost to be incurred, ect.) as well the process which can be developed by simulation, and it can interactively iterate several times in a way that the optimal solution can be achieved.

A few years ago, these operations were considered impossible, but thanks to the newest technologies, they are now possible for everyone. The responding time is exellent (just a few seconds), and this is also because the application fully uses the 64 bit addressing and the parallel calcultaion.

GPS^® MPS

Master Production Schedule

Allows, starting from sales forecasts, the formation of a production plan consistent with the availability of resources and materials. Operates on multiple time periods whose amplitude is set parametrically.
There are two levels of detail: by product family and product.
An interface with the commercial environment is available for comparing the plans in place with the backlog, and for automatically going from aggregated plans to plans per item.
The main available functions are:

• sales forecasts creation and management
• production aggregated plan formulation and management (per family)
• production detailed plan generation nad managemnet (per item)
• link to the backlog

GPS^® MRP

Material Requirements Planning

It is the most widespread materials planning methodology used by most companies in the world.
The software was projected to easily integrate with any management system form which it is able to get the data (BOMs, routing, stock, production and purchases)
The application complies with international standards, in more offers the following features:

• actual processing and simulation, with an unlimited number of versions
• planning by commit or warehouse, according to the management parameters of each part
• ability to calculate production lead times starting with routing or items data
• management of factory calendars linked to productive resources
• dating of employees requirements with the starting date of the routing phase to which they are intended
• "exhaustion" technique changes management
• sensitivity to the constraints of homogeneity of batch components

GPS^® PRM

Pegging Relationship Management

The module is based on a reticular planning technique that helps to overcome the constitutional limits of MRP:

• lack of "leeway" (start and end date are carefully calculated "at latest")
• lack of reactive mechanism which, in case of critical materials or resources, allow effects determination in advance

Using events that are already available in the MRP and reallocating stock and orders to the priority-based requirements, the system is able to:

• determine the constraints between events
• calculate the dates "as soon as possible" for each order
• identify the critical paths
• repositioning the citical events on a timely “forward"
  

We can highlight three types of situations from the comparison between "at the latest" MRP dates, and those "as soon as possible" from PRM:

• operation for which the two dates coincide: there are no margins for their execution
• operation for which "at the latest" dates are more than those of "as soon as possible": the difference is the tolerance (margin) allowed in the execution
• operation for which "at the latest" dates are before those of "as soon as possible": this is the case of delays

The most significant features, among the other ones, are:

• difining realistic dates for reaching the goals established by independent requirements
• support to the reminder (the system shows what is needed and to which is intended)
• automated proposition of production launches based on the availability of components

 From the foregoing, it is clear that the PRM module is a prerequisite for making a proper production resources planning.

GPS^® RCP

Raw Capacity Planning 

The module aims to develop a production plan, consistent with the availability of materials and production capacity.
For finished products (singles or groups) capacitive "macro constraints" and batching rules are defined.
The analysis is carried out over several production periods, parametrically defined.
Taking into account the availability of materials (for each period, at whatever level of BOM), defined by the MRP-PRM and the "macro constraints", the system determines production orders "feasible" in the period under review.
In case there is not sufficient capacity, orders are moved to lower priority in the next period. If the saturation of resources are not reached, orders of following periods are anticipated, as long as they have the necessary availability of materials.

GPS^® CRP

Capacity Requirements Planning 

Using production orders already in place and those proposed by MRP, this module is able to define the load profile of resources, thus generating the capacity requirements plan.
PRM ensures the consistency of temporal events: the forward repositioning of the critical paths causes realistic resource consumption forecasts (there are no oreders in the past,and no orders in the future with prerequisites in the past).
The calculation is made by adding every order to its production process; the system provides the level of saturation, in differetn periods, for each resource, with two versions:

• activities located "at the latest"
• activities located "as soon as possible"

highlighting, in both cases, the situation of overload and underutilization.
It is interesting to note that the vision "as soon as possible" offers the scenario with more capacity utilization, and that possible situations of non-use are unsolvable because of the lack of materials.

GPS^® FCP

Finite Capacity Planning

This application is intended to relocate production activities over time taking into account the profiles of availability of resources involved.
For all orders, it is made a reservation timed at "as soon as possible" of the resources demanded, so that they are destinated based on priority.
Before sending late opreations, the system attempts to divert on possible alternatives.
In case the availability is not sufficient to honor all the activities included in the analysis period, the lower priorities are moved forward.
This repositioning in chronological order is reversed, by implosion, and the business requirements are covered.
The finite capacity planning provides some important directions:

• start and end dates of the orders realistically calculated, taking into account the actual plants availability highlighting delays
• evaluation of the medium-term goals coverage dates
• interception of "bottlenecks" with the consequences on the finished products
