Abstract: Flexibility has been recognized as a key competitive advantage for any manufacturing newlineorganization. It is particularly important in the current manufacturing environment with the newlinegrowing dominance of high mix and low volume production. newlineFrom the survey of worldwide research, it is found that most of the researchers have newlinetaken Flexible Manufacturing Systems (FMS) as highly flexible and highly automated newlinesystems essentially operating in a real time control mode. However, this capability is capital newlineintensive and many SMEs of India and other developing economies cannot afford this. For newlinesuch organizations, there is a need to evolve the introduction of automation in the decision newlineand information systems in a phased manner. To develop such kind of FMS, it is more newlineimportant to fix proper levels of flexibility and automation and to decide which type of newlineflexibility should be used to optimize the performance within the constraints of cost. newlineThe objective of this research effort is to identify the right levels of flexibility, newlineintegration and automation on the theme of Semi-Automated Flexible Manufacturing newlineSystems. A SAFMS employs an online control strategy that may not be real time. In other newlinewords, it may be associated with alternative modes of decision and information delays. The newlinelevels of these delays depend upon levels of automation. An SAFMS is viewed as newlinerepresenting FMS system under phased development from the point of view of levels of newlinecomputerization at operational levels. newlineA discrete event simulation model was developed to study the performance of a newlineSAFMS with various levels of flexibility and automation. Different scenarios have been newlineinvestigated with respect to the design and operation of SAFMS. Initially, the facilities such newlineas machines and transportation systems are assumed to be continuously available without breakdowns. In the subsequent scenarios, it is assumed that there are inherent delays in newlinecapturing the shop floor status and taking control decisions.
