It is possible to use the same matrix concept but with a differrent perspective.
Factors such as the transferred weight or the number of routes executed.
These matrixes will help to make the decision of the relative location of the departments in the factory plant
Muther’s 8 factors. Wait factor
This factor covers the study of the three main warehouses
Raw materials, work-in-process and final product.
This factor objective is to determine the required space by each one of the warehouses.
Due to the magnitude of the warehouse study, a specific layout project must be outlined.
Because the warehouse layout is closely related with its management (planning and control), it will not be studied in this book.
Muther’s 8 factors. Service factor
Analyze two different characteristics.
The study of environmental workspace conditions
Brightness, noises, smells, minimum working space.
Decide what the acceptable parameters are with respect the OHSA regulations and the Labor Risks Prevention Law.
The working conditions are analyzed, but concerning the plant service staff.
These services are mainly, quality, logistics and maintenance.
Minimum maneuver space for the forklift trucks or other special equipment used.
Muther’s 8 factors. Building and change factors
Analyzes the actual useful surface of the building.
The plant shape, the columns, the window situation for ventilation, and areas of possible extension.
The surface area covered by gantry cranes limits the number of layout alternatives.
The proposed layout will not be valid forever.
The factor intends to observe, from a critical point of view, the adopted solution.
The application of this factor is without a doubt the most difficult part of the study.
Ask for future company plans.
This chapter has demonstrated how material flow can significantly be improved by means of layout analysis. In this kind of improvement projects, the study of the current situation allows to identify constraints that reduce the number of possible alternatives to be considered. The proposed improvements will reduce the material flow, allowing the company to raise the one-piece-flow proposed by the Lean Manufacturing philosophy.
