What is GD.findi?

GD.findi is a revolutionary production simulator that innovates production process system planning and factory floor plan planning.


With conventional production simulators, each case of production process planning requires a specialist to undertake the time-consuming process of developing a simulation program tailored to that individual situation. On the other hand, GD.findi does not require programming to work. Simply by using our superior graphic user interface, onsite factory engineering staff can develop factory floor plans or production process plans on their own. Then they can immediately execute simulations. GD.findi has introduced such innovative engineering to the manufacturing field.
By employing GD.findi, users can virtually construct not only manufacturing facilities, but also distribution centers or service facilities such as medical care organizations. That allows them to craft appropriate productivity-enhancement policies. The results of such simulations facilitate visual confirmation of optimum layout, the order of production implementation, plant and equipment performance, inventory space, delivery routes and delivery methods, as well as team building among the work force.

These operations ensure fast and effective consensus building within teams. As a result, users can smoothly and without delay implement factory floor planning, equipment design, procurement, education and training of staff, as well as other steps needed to get production up and running.
Furthermore, not only can these results be confirmed visually, they are also recorded numerically. Therefore, they can be compared with draft designs using various types of KPI (key performance indicators). As this numerical data can be used for computing product costs, compiling estimates, etc., that also facilitates the establishment of appropriate prices.
What makes possible these outstanding results is the fact Lexer Research, the creator of GD.findi, has accumulated a wealth of engineering expertise over many years. GD.findi is a simulation technology guaranteed to deliver manufacturing and logistical knowledge and solution methods from management circles to the factory floor.

Why do we say that GD.findi is such a trailblazing simulator?


imageAs those who have used them well know, conventional simulators can definitely be complicated and demanding. "This is a real pain to use!"

Conventional simulators make use of animation to produce results that are easy to understand visually. Although people tend to think that data input is also easy to handle, behind the scenes it can actually prove quite troublesome.

Why should that be so?

Actually, what happens behind the scenes with conventional simulators is that software programming has to be carried out separately for each factory. Moreover, since various assumptions naturally change, changes to the software program often become necessary.
Consequently, with this outdated approach, it takes a considerable amount of time even for a professional simulation programmer to accomplish the task.
The result is that they cannot be used effectively in engineering planning, and in many cases are used as nothing more than presentation tools. All too often, they end up not being utilized at all.

Programmer have to write specific control program.

imageConventional simulators are difficult to use.
Well then, what makes GD.findi truly revolutionary?

With GD.findi, a member of the engineering staff who is not a simulation programmer can perform the necessary operations.

Why should that be so?

GD.findi requires two types of data for simulations: the production process (the manufacturing sequence) and the floor plan (layout). For both, mouse operations are sufficient to accomplish all setup steps.
Moreover, since the data for the production process and the floor plan are established independently, the operator can verify the results of revisions through cut-and-try testing of various assumptions.Thus, hypothesis analysis and estimation work becomes much more efficient.

Special Features

Simple operations

Since an easy-to-understand GUI (graphical user interface) is provided, factory engineering staff can carry out simulations after only a few hours of training.


With this service, a client is not dependent on its own IT environment. Since a company that is determined to do business globally can make use of GD.findi from anywhere in the world, it can perform simulations in timely manner and share information concerning simulation results globally. In other words, GD.findi makes possible production system designing without limitations of space or time.

Professional services

Our consultants, who are well versed in production systems and actual plant conditions, provide conscientious consulting services to our customers. From various angles they propose ways to put "production system simulations" to work, to ensure appropriate responses to management issues and on-site problems within the manufacturing sector.

GD.findi helps you to solve the problems in production system design.

Technicians who design the production system should efficiently conduct a great deal of verification while always having conflicting goals of "cost reduction" and "improvement of productivity."
GD.findi supports such technicians and enables to complete quick and efficient design.

Production system analysis by GD.findi

"Material Flow Chart" which is giving an awareness of problems

The material flow chart is an overlapped of progress graph, Gantt chart (ガントチャート), and cycle diagram, and it is also a very effective tool for the analysis of production system. We recognize the production system as "item to be flowed" (station) and "flowing items" (materials) and by overlaying the behavior of both items (subject and object), it enables to support the understanding of the production system.
