5. Reconfigurable Manufacturing System (RMS) :<br />

Proceedings <strong>of</strong> the National Conference on<br />

Trends and Advances in Mechanical Engineering,<br />

<strong>YMCA</strong> <strong>University</strong> <strong>of</strong> <strong>Science</strong> & <strong>Technology</strong>, Faridabad, Haryana, Oct <strong>19</strong>-<strong>20</strong>, <strong>20</strong>12<br />

The reconfigurable manufacturing systems are prepared for specific way <strong>of</strong> manufacturing or modification (Rogers<br />

et al, <strong>20</strong>03).The reconfigurable manufacturing systems are those systems that are designed for Rapid change <strong>of</strong><br />

structure as well as hardware and s<strong>of</strong>tware components. In other words, the reconfiguration is the process <strong>of</strong><br />

changing the present configuration to a new one, which may involve changing the set <strong>of</strong> processes. .RMS goes<br />

beyond the objectives <strong>of</strong> FMS by permitting the reduction <strong>of</strong> Lead-time for realizing new systems and reconfiguring<br />

new systems. It has more flexibility in changing as per demands.<br />

5.1 Benefits <strong>of</strong> reconfigurable manufacturing system<br />

Following are the derived benefits <strong>of</strong> RMS<br />

1 Increased product quality<br />

2 Increased product varieties<br />

3 Minimize lead- time <strong>of</strong> realizing new system<br />

4 Ease prototype developments<br />

5 Providing more flexibility<br />

6 Fast in upgrading and quick action in new technology<br />

5.2 Disadvantages <strong>of</strong> reconfigurable manufacturing system<br />

1 Expensive system<br />

2 Expansive controls<br />

3 Difficult set up <strong>of</strong> machines<br />

4 Difficult selection <strong>of</strong> machine way <strong>of</strong> process and modules<br />

5 Difficult measurement or comparisons for changeability, reconfigurablity<br />

6 Difficult to prepare prototype model<br />

6. Different techniques <strong>of</strong> JIT, RMS and FMS:<br />

From the literature review and according to (Burbidge, et al.<strong>19</strong>91), Reconfigurablity and flexibility can be developed<br />

by adopting different techniques as follows:<br />

1 Control<br />

2 Measuring technique<br />

3 Estimating technique<br />

Minimize wastage <strong>of</strong> money, material, time and other…<br />

Increase production flexibility and customer satisfaction<br />

JIT<br />

FMS + RMS<br />

Provide only production flexibility<br />

7. Factors that affect the implementation <strong>of</strong> JIT, reconfigurable and flexible Systems design<br />

For design any manufacturing system, there are so many factors that can be in mind:<br />

1 Proper Implementation<br />

In the industry, it should be proper implementation for JUST-IN-TIME process and its working output.<br />

2 Cooperate<br />
