Abstract
This work presents two proposed heuristic schemes for the manufacturing plant layout planning as a simple approaches capable to solve the large scale problems. Each approach searches to find the sub-optimum relative arrangement of departments, minimizing the total material handling costs and considers the fundamental layout planning parameters which can be outlined as : The material handling cost emmitted from each department, departments ranks among job sequencing, departments areas and departments shapes
The first technique is the Multi-Index approach, it represents a layout
. construction heuristic technique I searches over ranking the departments in a sequence according to a planning factor designed through a multi-indexing procedure over •the above mentioned planning parameters, where the recieYing department should be assigned to the first rank in the resulted sequence. With the resulted sequence departments should be arranged in the plant site in a line pattern, rectilinear pattern and a mixed mode pattern as required gMng the sub-
,optimum relative arrangement.
The second technique is the Node-Exchange approach , it represents a layout construction heuristic technique starts with any initial departments sequence r this sequence starts with the recieYing department. This method manipulates the planning parameters to utilize the total flow cost between departments pairs and searches over an iterative procedure of exchanging the departments sequences assigning the recieving department to the first rank of fixed sequence.’ The method considers that each department in an intermediate sequence lies under two potential polarities: the first one corresponds its interacting to the leading departments group, while the other one corresponds its
interacting to the following departments group. With the resulted sequence departments should be arranged in the plant site in line pattern , rectilinear pattern, and mixed mode pattern as required gMng the sub-optimum relative arrangement.
Both the first and the second techniques were evaluated among CRAFT & MICRO-CRAFT solutions, where the results appeared that the second approach is more effecient than the first approach. taking into consideration that both the two methods consider the real shape of departments
