Equipment uptime dictates revenues

On the Coefficients of Variation of Uptime and Downtime in Manufacturing Equipment

It was reported in the literature that the coefficients of variation of uptime and downtime of manufacturing equipment are often less than 1. This technical paper is intended to provide an analytical explanation of this phenomenon. Specifically, it shows that the distributions of uptime and downtime have the coefficients of variation less than 1 if the breakdown and repair rates are increasing ...

Uptime Improvements for Photovoltaic Power Inverters

For optimum performance, the expansion of solar energy installations requires a robust and reliable infrastructure of panels, inverters and system control. Because of the geographically distributed and sometimes remote deployment of these solar power installations, reliability and performance is paramount to wider-scale adoption of these systems. Thus, it is very important to monitor the perfor...

Optimal design of uptime-guarantee contracts

Uptime-guarantee maintenance contracts reflect the obligation of service providers to maintain full functionality of equipment in certain fractions of working time in a period. In this paper, we study the optimal design of uptime-guarantee contracts for a service provider who does not know the customer’s exact valuation for having the equipment up and running per unit of working time. We first ...

Subnational Revenues: Realities and Prospects

The traditional theory of fiscal federalism prescribes a very limited tax base for subnational governments. The only "good" local taxes are said to be those (1) that are easy to administer locally, (2) that are imposed solely (or mainly) on local residents, and (3) that do not raise problems of "harmonization" or "competition" between subnational governments or between subnational and national ...
