This paper considers a multi-product newsboy system that produces multiple products for fulfilling independently uncertain demands, which share the same production capacity. To deal with possible shortage of limited capacity, productions can be outsourced. We consider two outsourcing strategies: zero lead time outsourcing, and nonzero lead time outsourcing. The structural properties and solutio...

Today's progressively complex healthcare landscape increasingly demands leaders who are adept at managing change in uncertain environments. Representing this country's largest group of healthcare workers, RNs influence how research translates to practice and ensure quality patient outcomes. Doctoral programs provide prospective nursing students with opportunities to pursue degrees focused on re...

It is predictable that the precipitous decline in the number of available children for adoption will find many Illinois couples pursuing the surrogate route, as has happened in other states. The current uncertain status of Illinois law regarding surrogate contracts demands legislative focus and direction. To prevent protracted litigation as in other jurisdictions and to prevent injustices to th...

A significantdbut underutilizeddwater resource is reclaimed water, i.e., treated wastewater that is reintroduced for various purposes. Especially in water scarce regions, reclaimed water is often the only remaining source of water to meet increasing population and water demands. In this paper, we develop a newmodel formulation for the cost-effective branched reclaimed water network design and s...

this article proposes composition of fuzzy sets theory with discrete-event simulation and puts it into application in order to model uncertain activity duration in simulating a real-world system. the purpose of this paper is to assess the usefulness of fuzzy simulation for modeling uncertain activity duration, especially when insufficient or no sample data is available. in this research, fuzzy ...

This paper develops a single wholesaler and multi retailers mixture inventory distribution model for a single item involving controllable lead-time with backorder and lost sales. The retailers purchase their items from the wholesaler in lots at some intervals throughout the year to meet the customers’ demand. Not to loose the demands, the retailers offer a price discount to the customers on the...

The vehicle scheduling problem (VSP) is a problem of interest to many researchers and practitioners. The general VSP is concerned with minimizing the total distance associated with a fixed set of vehicle routes by determining which vehicles will satisfy the demands at various customer locations. The design of most general distribution systems usually involves the assignment of permanent custome...
