yarn tenacity is one of the most important properties in yarn production. this paper addresses modeling of yarn tenacity as well as optimally determining the amounts of the effective inputs to produce yarn with desired tenacity. the artificial neural network is used as a suitable structure for tenacity modeling of cotton yarn with 30 ne. as the first step for modeling, the empirical data is col...

Vitamin A enriched rice (Golden Rice) is a cost-efficient solution that can substantially reduce health costs. Despite Golden Rice being available since early 2000, this rice has not been introduced in any country. Governments must perceive additional costs that overcompensate the benefits of the technology to explain the delay in approval. We develop a real option model including irreversibili...

Surveillance, and Reconnaissance) solutions for network-oriented defense will improve operational capabilities, flexibility and cost efficiency. The realization can be evolutionary, starting with networking of existing systems.

A novel procedure to find cost-optimal sensor networks is proposed. Cost is minimized subject to qualibing constraints that are related to certain requirements of data reconciliation. One basic qualibing constraint is a desired level of precision of reconciled values for a selected set of variables. Since precision requirements lead to multiple solutions, other qualifying constraints are propos...

In this paper, we will describe the planner UPWARDS, competing in the sixth international planning competition. Our primary focus will be on the novel contributions of the planner: in particular, the application of symmetry breaking, mobile analysis and tunnel macros in sequential cost-optimal SAS+ planning. A brief outline of UPWARDS itself is then

This paper analyses the importance of productive specialisation in explaining cost efficiency differences between banking companies. Taking as reference the Spanish banking sector during the period 1985-96, the study shows that if cost efficiency measurements are corrected for the effect of different specialisation by the estimation of separate frontiers for four different groups of competitors...

This paper is concerned with the problem of controlling a truncated general immigration process, which represents a population of harmful individuals, by the introduction of a predator. If the parameters of the model satisfy some mild conditions, the existence of a control-limit policy that is average-cost optimal is proved. The proof is based on the uniformization technique and on the variatio...

In the traditional cost-efficiency model, the information about each decision unit includes inputs, outputs, and the input prices are fixed and specific. In practice, the price of the inputs often fluctuates at different times, and these prices for the decision-making unit are time-dependent. By the traditional method, the efficiency of decision units is impossible in the presence of time-depen...

The future of manufacturing is here, compliments of intelligent machines that enable people, processes, products and infrastructure to seamlessly coordinate, creating finished goods that are more time-and cost-efficient to produce — and meet, if not exceed, customer expectations.

New and increasingly advanced data services are driving up wireless traffic, which is being further boosted by growth in voice applications in advanced market segments as the migration from fixed to mobile voice continues. Meanwhile, difficult market conditions have caused a number of operators to delay making substantial investments in upgrading their networks to higher capacity technology. In...
