Abstract In today's competitive global market, effective utilization of industrial resources play a vital role. Here lies the importance of efficient layout or re-layout of the industry. The physical arrangement of all the departments, storage areas, utilities areas must be critically planned to avoid the wastages and the bottlenecks.
This paper presents a case study undertaken to develop the efficient plant layout by using Systematic Layout Planning (SLP) technique, The basic analysis of existing layout was done by establishing relationship of different activities in the process flow. The material flow analysis was done by considering load matrix and cost matrix. After analysis of existing plant layout, three alternative layouts are developed by using SLP technique. The efficient plant layout developed has resulted in 55.25% savings in material handling distance and about 16.66% increase in productivity.
Keywords Plant layout, SLP, load matrix, relationship
In competitive environment, productivity of the industrial unit has got ultimate importance. Efficient plant layout is one of the effective tool to enhance the productivity. Most plant layouts are designed for initial conditions of the business. However these layouts provide many bottlenecks during growth period. Hence as long as capacity grows, it has to adapt the internal and external changes for which efficient re- layout is necessary.
Many researchers have provided a number of techniques to optimise the layouts. The quantitative and the qualitative measure of the techniques may differ, however the objectives are same. Hence the selection of a best alternative technique is a matter of justification.
To design or redesign the facility layout of a manufacturing process, it is possible to apply many techniques. Each one is based on a specific idea and goal to be achieved. The comparison can be made based on the production process parameters such as material flow, material handling cost, time, throughput etc.
In the case study of a small scale textile industry, the Systematic Layout planning technique is used to develop three alternative layouts. SLP is one of the most frequently used methods in the layout design of the facilities. It includes three specific phases :
Data collection and analysis
Searching among the possible layout solution.
Evaluating alternatives and selecting the best layoutt.
This paper refers to a small scale Textile Industry manufacturing Turkish towels and napkins.
The manufacturing process involves the flow of material as shown in the figure (1)
Figure 1: Manufacturing Process
MOTION AND TRANSPORTATION
The term motion is used for movement of people and transportation for the movement of the material. Quantitative data was obtained to calculate the total distance travelled in terms of motion and transportation during the manufacturing process of existing plant layout. (Table 1). The table represents the distance between different locations for each major process in the manufacturing. The data serves as the baseline and is useful in determining the degree of closeness necessary between different departments for material flow. Efforts are made in the layout design to place the departments, having more material flow, close to each other to minimize the material handling cost. It was seen that in the existing plant layout (Fig. 2) the work flow was not optimum due to poor adjacency of the departments.
The various departments shown in the layout are
H .R .Office
Raw material storage
Power loom section
Development of alternatives by using SLP
By applying SLP technique and considering the constraints three possible alternative plant layouts A, B and C were developed as shown in Figure 2. The motion and
transportation in modified plant layouts A,B and C are analysed and presented in the table 2.

Comparing the results of new developed layous A,B and C with existing layout, it is observed that :
Layout A results in 785.85 meters savings in total distance. ( 39.91% )
Layout B results in 1175.85 meters savings in total distance ( 55.23% )
Layout C results in 1120.85 meters savings in total distance ( 52.65% )
In new layouts A,B and C all the departments are systematically arranged so that efficient material flow is obtained.
Maximum material flow distance is saved in plant layout B ( 55.23%)
Plant layout C is provided with effective utilization of available floor space in weaving section and thereby increasing the production by 33.33%
Plant layout C is also provided with the flexibility to adapt Auto looms in weaving section which will result in great
savings in labour requirement so that 31 labours are not required.
Automation of material handling is suggested by using trolleys and beam lifting devices.
