Chapter Summary

Location decisions are the strategic decisions that require large financial investments and they are irreversible in nature. A number of factors like market related factors, tangible or cost factors and intangible or qualitative factors, affect and are affected by the location choice.

Models and techniques such as break-even analysis, factor rating technique, and transportation method of linear programming help managers in making location decisions. Since these models work on quantitative basis; therefore the influence of qualitative factors should be considered by managers to decide the location choice.

The physical disposition of the facilities of a plant is referred to as the plant layout. The basic types of layouts are: process layout, product layout, fixed-position layout, cellular manufacturing layout and hybrid layout. A process layout is the layout in which similar machinery are grouped together.

In product layout the machines are arranged according to the progressive steps by which a product is made. In a group technology layout, dissimilar machines are grouped into cells, and each cell functions like a product layout within a larger job shop or process layout. In a fixed layout, all the necessary men, materials, and equipment are brought a fixed location where the product is actually manufactured.

A hybrid or combination layout constitutes combination two or three types of layouts. In case of designing service layouts, there exist two types based on the degree of customer contact. One is designed around the customer service and the other around the technology, processing of physical materials, and production efficiency.
