In this paper, we describe privacy-preserving protocols for a scheduling service in eHealth applications. The scheduling mechanism that we propose protects sensitive information that are handled by the system. However, it still allows for a fair distribution of tasks and restricting the task assignment to caregivers with specific qualifications.

Abstract This paper establishes an improved optimization model of logistics distribution vehicle scheduling based on “Stranger Problem”, which the common vehicle scheduling model does not consider, by defining two parameters named “Strange Degree” and “Strange Coefficient”, and makes a experimental computation by using improved C-W algorithm. The computational results prove the feasibility and ...

In this paper, we propose an aanity-based self scheduling scheme (ABS) for software shared memory system. In this scheme, the static aanity between processor and initial data distribution is considered when scheduling, and the synchronization overhead is reduced greatly when load imbalance occurs. Comparized with previous schemes, ABS performs better in metacomputing environment.

In this paper, we discuss a new decision-support system for scheduling paper manufacturing and distribution. Scheduling production and distribution of paper is an extremely complex task requiring the consideration of numerous constraints and objectives. Problem complexity is compounded by process interactions wherein the scheduling of one stage of the production process may negatively impact do...

heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

Bacterial self-replication is a complex process composed of many de novo synthesis steps catalyzed by a myriad of molecular processing units, e.g., the transcription-translation machinery, metabolic enzymes, and the replisome. Successful completion of all production tasks requires a schedule-a temporal assignment of each of the production tasks to its respective processing units that respects o...

Abstract Forecasting electrical energy demand and consumption is one of the important decision-making tools in distributing companies for making contracts scheduling and purchasing electrical energy. This paper studies load consumption modeling in Hamedan city province distribution network by applying ESN neural network. Weather forecasting data such as minimum day temperature, average day temp...
