MODELO DE INVENTARIOS PARA EL SERVICIO POST-VENTA DE REFACCIONES A UNA RED DE TELECOMUNICACIONES

Abstract

The after-sales service is an important source of revenue and pro t for OEM (Original Equipment Manufacturer) Telecom rms. A good performance of the after-sale service provides a competitive advantage for the OEM rms against their competitors, whether for the acquisition of new customers or retaining existing ones. However, the design and management of the aftersales service face up diverse challenges. This research work supports the after-sales service by developing a mathematical inventory model that leverage the availability of spares versus the service availability of the telecom network in case of an equipment failure. In so doing, (i) the system is de nied through the Viable System Model methodology, (ii) the time series of the supply chain are analyzed by using fractals and complex networks tools and the system is characterized by a heavy tail distribution, (iii) and considering last outcome the demand is modeled in the inventory model by a discrete stable proces. The built model provides an alternative in literature to model demand with a heavy tail distribution versus the used of Poisson process.
