Revision of Layout

Revision of Layout

A good plant layout involves not only designing and installing the layout for the first time but also revision of existing layout.

The best layout becomes obsolete over a period of time if it is unchanged for number of years.

Revisions ranging from minor alterations to a complete dismantling of existing structure and installation of a new layout becomes necessary.

Reasons for Revision

Expansion Technological advancements Improvement in the layout.

Expansion

It is a natural feature of any industrial establishment. A plant may expand if:-

Increase in the output of existing product

Introduction of a new product in the same line

Diversification of the lines of activity.

Technological advances

Industrial research is a insurance against obsolescence of products.

Replacement of labour by machines Developments in fuel and energy Developments in process Development in materials Improvements in product design Advancement in information technology

Improving the layout

Layout needs constant attention from the management. The limitations in a layout go unchecked for two reasons:-

The evils of a poor layout are a hidden cost not revealed even by the best accounting method.

Even if they are revealed, the management will be unwilling to initiate remedial steps.

The defects to be rectified are:

Materials and work in progress move at a lower rate than expected

Materials handling costs are high There are delays in production schedule There is increased cost of production and

reduced operational efficiency

Layout Planning

Designing and installing a layout for the first time and its subsequent revision may be looked after by engineering and planning department.

The process of preparing a layout is an art as well as science, inspite of advances made in the use of layouts.
