In order to solve closed-loop logistics network design problem in the low-carbon economic environment, in this paper, queuing theory is used to calculate the amount of storage of reverse logistics nodes and interval number is used to describe the uncertainty of the logistics network, a bi-objectives logistics network design model which minimum the total cost and carbon emissions of logistics ne...

In this paper provides the results of research on the development of the method of constructing a model of customs procedures in terms of the theory of queuing systems based on their description by means of functional modeling IDEF0. The technique is based on use of the integrated IDEF0 models and theory of queuing systems with the ability to transition from a description of the system in IDEF0...

Environmental stress testing (EST) is a reliability test for the semiconductor products that is concerned with how products perform its intended functions under some environmental conditions. Planning, implementation and delivery schedules are affected by the outcome of these tests and it is crucial to determine the throughput of the EST process. In this paper we present an efficient modified a...

In this paper, we investigate a call-admission and handoffcontrol framework for multi-tier cellular networks. We first propose and compare Call-Admission Control (CAC) algorithms based on the cell-dwelling time, by studying their impact on the handoff-call dropping and new-call blocking probabilities and the channel partitioning between the two tiers. Our results show that a simple, cell-dwelli...

Structural reliability is an important method to measure the safety performance of structures under influence uncertain factors. Traditional structural analysis methods often convert limit state function polynomial form whether structure invalid. The parameters mainly exist in intervals. This requires a lot calculation and difficult achieve efficiently. In order solve this problem, paper propos...

Optimization of computer communication network based on reliability theory is problem with multiple constrained conditions. Based on the analysis of reliability theory of computer communication theory, this research discussed the multiobjective optimal model in computer communication network combining with principle of multi-objective optimal design and completed a set of analysis on network co...
