A Systematic Transition To Flexible Manufacturing, Sema E. Alptekin, Daniel L. Webber Dec 1988

A Systematic Transition To Flexible Manufacturing, Sema E. Alptekin, Daniel L. Webber

Industrial and Manufacturing Engineering

The transition from basic automation to flexible manufacturing is an expensive and tedious procedure. It requires meticulous planning and almost clairvoyant forecasting to insure that the initial flexibility obtained is sufficient to allow growth and expansion in the future. This paper will suggest a systematic and methodological approach to achieve optimal flexibility and describe the present results of its application to an ongoing system transformation. Conclusions based on existing levels of completion are presented along with identification of critical and non critical flexibility requirements. The considerations and steps taken are summarized in a procedural format which may then be applied ...

Proposed Scheduling Methods For Printed Circuit Board Assembly, Tali Freed, Ezey M. Dar-El, Oded Z. Maimon

Industrial and Manufacturing Engineering

The current practice in the assembly of electronic components on printed circuit boards (PCB's) is serial production, a process characterized by very long set-up times.

However. with the advent of efficient on-line process information, new production control methods are now possible. This paper proposes two new production methods - the Grouped Set-up (GSU) method and the Sequence-Dependent Scheduling (SDS) method, which can significantly reduce set-up times.

It is shown that the GSU always performs better than the SDS method in terms of total production flow (throughput). while the SDS performs better than the GSU method in terms of work-in-process (WIP ...
