In many manufacturing application the system reliability performance is a key issue in order to obtain the best performance of the equipment. The paper focuses on the reliability enhancement of complex systems containing redundant architecture using the Reliability Importance (RI) methods in order to evaluate the weight of each element on the whole system reliability. The first part of the paper is...
This work aims at systematically characterizing urban mobility. There are several possible approaches to the problem but this work focus on reducing commuting times and emissions using the current infrastructures and without increasing the cost to the end user and doing so in an effective and sustainable way. A set of pairs of destinations and origins was chosen to represent usual commutes and cover...
The growth of electricity demand in Argentina leads to the system expansion in generation, transmission and distribution networks in that country. Regarding distribution networks, a typical problem arises when a distribution company or a large customer must choose the location of its electrical substations; because this decision will determine the total cost of the installation. With the aim of minimize...
This paper proposes a cost-aware opportunistic relaying scheme to minimize total cost in decoding and forwarding (DF) relay networks with power constraints. In the proposed scheme, a relay is selected such that it costs minimally among relays which correctly decode the signal from the source and have sufficient power to transmit the signal to the destination. We derive the outage probability and the...
This paper makes a system research on the Animation derivatives evaluation process and methods and analyzes the main problems of design evaluation, meanwhile putting forward of constraint condition Animation derivatives evaluation system and model based on cost control and function. From three dimensions it devises nine secondary indexes and forty four triple the evaluation index system, combining...
Analyzed and evaluated the impact of quality and value indexes the result of the life cycle of the product. Formalized the optimization procedures of quality / value parameters of model structure for the achievement of pre-performance caused by the objective function.
It has been found that significant benefits can be achieved if suppliers are involved in the early phase of new product development process. However, in practice, this approach do not always bright in the desired benefits, if does not have a negative influence on the buyer firm's performance. Trying to solve this problem, this paper describes a new management model based on a multicriteria sorting...
Since the value measurement to knowledge-based economy has become a powerful tool, it is necessary to expose a theory analysis on value measurement to the technology-based knowledge product (the VMTKP). Based on the costs and benefit, we create the measurement formula, and build the value measurement model for the VMTKP. Whatpsilas more, analysis to the related influence factors, variables and parameters...
The earned value measure is introduced into the cost and schedule control of warship planned maintenance for the over budget and schedule delays problem. The flowchart and application range of earned value measure is summarized. The application procedure of the earned value measure in the cost and schedule control of warship planned maintenance is given. Then the over budget and schedule delays are...
