The design and planning of resilient supply chains is a major challenge due to the increasing complexity of these systems that operate in a global market and therefore are more exposed to disruptions. In the present work a design and planning model that integrates demand uncertainty is applied to five supply chain structures that are submitted to different types of disruptions. Disruptions are ...

BACKGROUND For mothers who have just given birth, the postpartum hospital stay is meant to promote an environment where resting, healing and bonding can take place. New mothers, however, face many interruptions throughout the day including multiple visitors and noise caused by medical equipment, corridor conversations and intercom announcements. This paper argues that disruptions and noise on a...

  In this paper an Ant Colony (ACO) algorithm is developed to solve aircraft recovery while considering disrupted passengers as part of objective function cost. By defining the recovery scope, the solution always guarantees a return to the original aircraft schedule as soon as possible which means least changes to the initial schedule and ensures that all downline affects of the disruption are ...

Verpleging het uit ’n maatskaplike behoefte aan sorg vir siekes ontstaan. Verskeie groepe en individue het deur die eeue heen ’n verreikende invloed op die ontwikkeling van verpleging gehad en dit uitgebou tot die professie wat ons vandag ken. In die moderne wêreld oefen veral ontwikkeling in tegnologie ’n groot invloed uit — vergelyk byvoorbeeld die toekomstige rol van rekenarisering op gesond...

Circadian rhythm disorders (CRD) result from modern lifestyles characterized by long exposure time to blue light, shift-work, chronic stress and night-time social activities. The disruption of circadian rhythms represents an individual risk factor in the development various diseases, including neurodegenerative ones. Simultaneously, demographic ageing is associated with rising incidence disease...

-From a discussion of the disruption process, it is concluded that this process plausibly consists of the onset of a fine grain turbulence. This turbulence must be able to produce the large 1 aly values of the inductive electric field which are associated with the reorganization of the c at poloidal flux Y(r) and the current density Z(r) on the magnetic surfaces of radius r. It is then plausibl...

This paper considers the reliable multi-product multi-vehicle multi-type link logistics network design problem (RMLNDP) with system disruptions, which is concerned with facilities locating, transshipment links constructing, and also allocating them to the customers in order to satisfy their demand on minimum expected total cost (including locating costs, link constructing costs, and also expect...
