In the context of equipment leasing, maintenance service is usually bundled with leased and offered by lessor as an integrated package under a lease contract. The then responsible to prescribe effective policy keep operational in economical way. This paper investigates upgrade preventive (PM) strategies for industrial during successive usage-based contracts consideration warranty period, from lessor's perspective. accelerated failure time model age reduction are adopted capture effect usage...
Conventional preventive maintenance (PM) strategies under two-dimensional (2D) warranties are usually age-based or usage-based, which means that the implementation of PM activities is based solely on item age usage. In this paper, a new strategy, called 2D proposed for items sold with warranty. Under preventively maintained every K units L usage, whichever occurs first. The marginal approach used to describe effect and usage reliability by treating as random function age. Besides,...
Traditional maintenance planning problems usually presume that preventive (PM) policies will be executed exactly as planned. In reality, however, maintainers often deviate from the intended PM policy, resulting in unpunctual executions may reduce effectiveness. This article studies two imperfect with for infinite and finite horizons, respectively. Under former actions are periodically performed system is preventively replaced at last instant. The objective to determine optimal number of...
Abstract Background To provide safety data for efalizumab, a recombinant humanized monoclonal IgG 1 antibody, in adults with chronic plaque psoriasis. Methods A 12‐week, Phase IIIb, randomized, double‐blind, parallel‐group, placebo‐controlled trial. At 58 study sites the USA and Canada, 686 patients moderate to severe psoriasis received an initial conditioning dose of efalizumab 0.7 mg/kg subcutaneously (SC) followed by either 11 weekly doses SC or matching placebo. Main outcome measures...
Anti-inflammatory cytokine IL-10 produced and released from collagen–silica nanocomposites is capable of modulating macrophage phenotype in a 3D inflammation model.
Background Microvascular invasion (MVI) is a risk factor influencing the survival rate of patients with mass‐forming intrahepatic cholangiocarcinoma (IMCC). Purpose To investigate whether diffusion‐weighted imaging (DWI) could be useful in predicting MVI IMCC. Study Type Retrospective. Subjects Eighty surgically resected single IMCC (21 MVI‐positive lesions and 59 MVI‐negative lesions). Field Strength/Sequence Preoperative hepatic MRI (1.5T), including T 1 ‐ 2 ‐weighted images (T WI, WI),...
In this paper, we propose a descent derivative-free method for solving symmetric nonlinear equations. The is an extension of the modified Fletcher-Reeves (MFR) proposed by Zhang, Zhou and Li [25] to It can be applied solve large-scale equations due lower storage requirement. An attractive property that directions generated are residual function. By use some backtracking line search technique, sequence function values decreasing. Under appropriate conditions, show globally convergent....
We investigate a condition-based group maintenance problem for multi-component systems, where the degradation process of specific component is affected only by its neighbouring ones, leading to special type stochastic dependence among components. formulate into factored Markov decision taking advantage this property, and develop value iteration algorithm efficiently approximate optimal policy. Through both theoretical analyses numerical experiments, we show that can significantly reduce...
Postoperative delirium is a common complication in older patients, with poor long-term outcomes. This study aimed to investigate risk factors and develop predictive model for postoperative patients after major abdominal surgery. retrospectively recruited 7577 aged ≥ 65 years who underwent surgery between January 2014 December 2018 single hospital Beijing, China. Patients were divided into training cohort (n = 5303) validation 2224) univariate multivariate logistic regression analyses build...
Introduction The prevalence of dental caries (DC) among students in developing countries has increased at an alarming rate, and nutritional status been shown to be associated with DC children adolescents inconsistent conclusions. We aimed understand the trends aged 7, 9, 12, 14 years explore relationship between status. Methods recruited 16,199 China by multi-stage, stratified, random sampling methods from 2010 2019. Permanent were measured using Decay, Loss, Filling (DMF) index rate....
In this paper, a pre‐sale upgrade model is developed for repairable used products sold with two‐dimensional warranty policies. Two kinds of regions are considered, that is, rectangular and L‐shaped regions. The marginal approach to describe the effect age usage on product reliability by treating as random function age. optimal policy determined minimize dealer's total expected servicing cost which sum cost. Analytical properties solutions also investigated. Furthermore, five‐step presented...
