Abstract

Evaluating and selecting supplies are critical activities in the process of purchasing and supplying materials. Many manufacturing and service organiza tions operate in a con stantly changing business environmen t and occasionally have to reconsider their steps in terms o f supplier selection. This paper offers a methodology that takes into accoun t the im- pact of a dynamic business environment on the supplier selection process. This methodology represents an applicable tool supported by decision for the planned selection of a single supplier that changes with time out of a supplier group over a finite planning ho rizon. The suggested methodology has been tested in a large Israeli organization-Clalit Health Services, which comprises large-scale logistical entity working with hundreds of suppliers on an ongoing basis. Our analysis of application results shows that the suggested strategy of switching suppliers over a predefined planning ho-rizon according to the business environment forecast is over 10% more efficient compared to a strategy that does not change the leading supplier throughout the planning horizon. This average improvement is translated into expected efficiency gains on most operative dimensions which represent selection parameters, such as cost per unit, supply lead-time, reputation and more. Nevertheless, some of their value is lost due to some dimensions.
