Procedure in Production Flow Analysis
The procedure in PFA has the following steps.
- Machine classification : Classification of machines is depend on the operation that might be performed on them. A machine type is assigned to machines able of performing similar operations.
- Checking part list & production route information: For each of the parts, information on the operations to be taken and the machines needed to perform each of these operations is checked out carefully.
- Factory flow analysis : It comprise a micro level examination of flow of components through machines. Therefore, it permits the problem to be decomposed into a number of machine-component groups.
- Machine-component group analysis: It analysis suggested manipulating the matrix to form cells.
Several researchers have been subsequently built algorithm to solve the family- formation difficulty for manufacturing cell design. In PFA, a big matrix generally termed as incidence is constructed. Each of rows represents an OP code, and each of columns represents a component. We might define the matrix as Mij, where i refer the optiz code and j refer components for instance Mij=1 if component j has OP code i; or else Mij = 0. The objective of PFA is to bring together those components that require the similar set of OP codes in clusters.
