With the advent of the smart grid, new challenges arise for electricity distribution. In particular, reliable power distribution will become evermore dependent upon information and communication technology (ICT). With this increasing dependency comes a need for a deeper understanding of the availability of those ICT components that maintain the power grid. This paper presents a study in which a...

Firms that rely on functioning mission-critical equipment for their businesses cannot a¤ord signi…cant operational downtime due to system disruptions. To minimize the impact of disruptions, a proper incentive mechanism has to be in place so that the suppliers provide prompt restoration and recovery services to the customer. A widely adopted incentive mechanism is performance-based contracting (...

The Impact of Teams on Output, Quality and Downtime: An Empirical Analysis Using Individual Panel Data To investigate the size and the timing of the direct impact of participatory arrangements on business performance, we assemble and analyze extraordinary daily data – for rejection, production and downtime rates for all operators in a single plant during a 35 month period, more than 77,000 obse...

In this paper, lean buffering (i.e., the smallest level of buffering necessary and sufficient to ensure the desired production rate of a manufacturing system) is analyzed for the case of serial lines with machines having Weibull, gamma, and log-normal distributions of upand downtime. The results obtained show that: (1) the lean level of buffering is not very sensitive to the type of upand downt...

A method is offered to estimate downtime (the time to restore a facility to operability, not total repair time) for second-generation performance-based earthquake engineering. It applies in cases where downtime is primarily controlled by nonstructural systems (although red-tagging and lifeline failure are addressed); restoration begins immediately after the earthquake; and components are repair...

There is a significant desire by patients to reverse the signs of aging caused by photodamage. Numerous procedures for facial skin rejuvenation have been developed in an attempt to minimize the erythema, dyspigmentation, and rhytides associated with photoaging. The initial procedures developed for facial rejuvenation involve skin resurfacing via complete ablation of layers of skin. Of these pro...

PT Bintara Tani Nusantara merupakan suatu perusahaan manufaktur yang bergerak dibidang industri Pengelolahan Kelapa Sawit. Pada saat produksi permasalahan sering terjadi adalah mesin screw press mengalami downtime. Downtime pada mengakibatkan proses akan terganggu atau dapat berhenti beroperasi stasiun kerja selanjutnya. Untuk mencegah terjadinya downtime, perlu menerapkan sistem perawatan guna...

Photodamage is one of the most common reasons that patients visit a dermatologist's office. Carbon dioxide (CO(2)) laser resurfacing has always been the gold standard for reversing photodamage. Because of the relatively high incidence of side effects and the prolonged downtime associated with CO(2) resurfacing, new technologies have emerged to address photodamage. Portrait skin regeneration (PS...

Fault trees have long been used to estimate failure risk in earthquakes, especially for nuclear power plants (NPPs). One interesting application is that one can assess and manage the probability that two facilities - a primary and backup - would be simultaneously rendered inoperative in a single earthquake. Another is that one can calculate the probabilistic time required to restore a facility ...

This paper uses a discrete event simulation based direct method that allows an availability requirement to be used to predict required logistics, design and operation parameters. Parameters that affect both downtime and uptime are addressed in this paper.
